Definitions

  • the invention relates to a motor vehicle with a drive motor which generates waste heat, in particular an internal combustion engine, with a coolant circuit and with a latent heat store which can be arranged in this coolant circuit.
  • Latent heat stores are known which are able to store the heat supplied to them with high efficiency over considerable periods of time.
  • motor vehicles it is known, for example, from the publications briefly explained below in detail, to store the cooling water heat with the most compact and relatively light and inexpensive latent heat storage device, in order, on the one hand, for example after a night, after a weekend or after a week of downtime of the motor vehicle, in particular in the colder season to have warm air for the window defrosting and / or the cabin heating.
  • the cooling water heat can also be stored for preheating the cooling water in the engine or the engine oil, in order to make it easier to start the engine and to at least significantly reduce the warm-up time with its negative effects.
  • the first-mentioned application is a safety and comfort measure
  • the second application is a measure to reduce fuel consumption, pollutant emissions and wear and tear of the engine by avoiding or shortening its warm-up.
  • the cooling water in the insulating container which does not have a reheating device can cool completely, so that a warm start is not possible.
  • the frequent draining and refilling of the cooling water in spite of the pump is complex, can lead to cooling water loss and contamination and to accelerated corrosion.
  • DE-A-33 41 097 shows an insulating vessel installed in a motor vehicle, into which the cooling water can be pumped in and out by means of a pump.
  • the insulating vessel can be provided with an electrical heater that can be operated from an external (domestic) power network.
  • the insulating vessel takes up a lot of installation space, which is often not available stands, and for reheating an external power source must be available near the parked motor vehicle, which is often not the case.
  • DE-A-29 30 269 and 27 10 037 it is disclosed to provide a transportable or exchangeable heat store on the motor vehicle for absorbing the waste heat of the engine;
  • the hot heat storage device can be used separately from the motor vehicle for house and apartment heating, it can also be used for the auxiliary heating of the motor vehicle and can be heated by heating sources other than the engine.
  • the storage medium of the heat store usually a proportion of cooling water, can be pumped into the house and apartment heating systems.
  • the heat accumulator can optionally be heated from a cooling water secondary circuit via heat exchangers. An engine cold start cannot be avoided by means of these devices, and extensive, fixed installations are required to absorb the heat from the motor vehicle.
  • DE-A-26 35 632 discloses storing the cooling water and exhaust gas heat in insulated heat stores of the motor vehicle in order to preheat the engine after long periods of inactivity; other uses of the heat are also proposed. However, it is not shown how this should be done in detail.
  • the heat accumulator should be arranged in the vehicle or a trailer that can be coupled and be chargeable from the cooling water via heat exchangers or heat exchange circuits and from the exhaust gas heat. At stationary stations, the heat accumulator should be emptied or the trailer uncoupled or replaced, the heat should be used elsewhere. The cold start problem or vehicle preheating has not been addressed.
  • DE-A-32 06 239 describes a cell system for heat storage devices that are fixed to the vehicle or mobile, for absorbing the engine waste heat Proposed, the heat accumulator possibly separately in individual vehicle warming areas assigned to be accommodated in otherwise unusable vehicle compartments. Long-term heating should be achieved from engine standstill, cold start problems after long idle times are not addressed.
  • DE-A-33 26 572 finally proposes a portable, possibly with a handle, heat accumulator which can be electrically charged in the house and can then give off its heat to the vehicle interior heating. No use of engine waste heat is intended.
  • the latent heat store can be easily separated into the coolant circuit by means of self-closing, manually operated valve couplings, that the latent heat accumulator can be easily removed in a space (trunk) of the motor vehicle that is not otherwise required during a large part of the period of use of the motor vehicle, - That the latent heat store has at least one handle for its manual transport, and - That the latent heat storage includes an electrical heating cartridge that can be connected to a domestic power supply.
  • the invention thus consists in that the latent heat accumulator is accommodated in the trunk of a car or in other vehicles at a location where this latent heat accumulator is not very annoying, so that it can be removed at any time and without great effort.
  • a car driver can have the latent heat storage in his trunk in the cold season, which is not fully used during daily trips, for example to work or other short trips.
  • the latent heat storage can be removed from the vehicle like a suitcase.
  • the latent heat storage is closed its easy handling with a handle and with plug-in, self-locking coolant line connections and to heat it up after a long period of use with a house heating element.
  • the motor vehicle 1 designed as a passenger car has an internal combustion engine 2 as the drive motor, which can be cooled by means of a coolant circuit; the cooler, fan and other additional devices for the internal combustion engine 2 are not shown.
  • the trunk 3 of the motor vehicle 1 there is a latent heat store 4, which occupies a considerable space in the trunk 3.
  • the latent heat store 4 is switched on by means of coolant lines 5 in the main circuit or in a secondary circuit of the coolant circuit for the internal combustion engine 2, two coolant lines 5 are expediently provided in a manner not shown, one of which coolant heated by the internal combustion engine 2 supplies the latent heat store 4 and the other of which Promotes coolant from the latent heat storage 4 back to the internal combustion engine 2.
  • the latent heat store can absorb a considerable proportion of the coolant quantity of the motor vehicle in its well-insulated interior, or it can also be designed in such a way that it contains a well-insulated heat store that can be heated by the hot coolant flowing through it and the stored heat flowing through it to the cold one Can release coolant again.
  • the latent heat store 4 is equipped with two self-closing, manually operable valve couplings 6 and 7, to which the coolant lines 5 for the supply and discharge of the coolant can be connected by means of corresponding, also self-locking counter-couplings 9; It is expedient if the latent heat storage 4 and the two coolant lines 5 are each provided with a plug and a receiving part for the couplings, such that the two coolant lines 5 can be coupled directly to one another by means of the mating couplings 9, bypassing the latent heat accumulator 4. To enable these coupling processes, at least one of the end sections of the coolant lines 5 that can be connected to the latent heat store 4 is designed as a hose line 10.
  • the latent heat accumulator 4 is easily detachably mounted in the trunk 3 of the motor vehicle 1 in a manner not shown, for example it can be held by tensioning straps which can be easily closed and tensioned and also released again manually by means of snap, tension or quick fasteners.
  • the latent heat store 4 is provided with a handle 11.
  • the internal combustion engine 2 When the internal combustion engine 2 is running, it generates waste heat which is dissipated by the internal combustion engine through the coolant circuit.
  • the coolant heated by the waste heat flows through one of the coolant lines 5 to the latent heat accumulator 4 and releases at least part of the waste heat therein; the latent heat store 4 is thereby heated.
  • the coolant then flows back to the internal combustion engine 2 through the other of the coolant lines 5.
  • a conventional cooler can be used in this coolant circuit or in a coolant circuit parallel thereto, the flow of the coolant is expediently generated by at least one coolant pump.
  • the coolant can also flow through a conventional heat exchanger, which is used for air conditioning the cabin and / or cooling the engine oil.
  • the motor vehicle After the motor vehicle has been parked for a longer period of time, in particular overnight or even a few days during the cold season, the motor vehicle, together with its internal combustion engine 2 and the coolant, cools down with the exception of the latent heat accumulator 4 and the amount of coolant contained therein or the heat accumulator located therein ; the latent heat accumulator 4 together with the coolant or heat accumulator located in it, on the other hand, cools only extremely slowly, so it maintains the operating temperature of the internal combustion engine 2 at least approximately over longer periods, for example the periods mentioned.
  • a coolant flow through the coolant lines 5 begins, whereby the hot or heated coolant located in the latent heat store 4 is conveyed to the internal combustion engine 2 and heats it up very quickly to a considerable mixing temperature.
  • the internal combustion engine 2 thus reaches a considerable temperature very quickly after start-up; it does not have to warm up to this mixing temperature starting from the starting temperature.
  • a mixing temperature can be set, which can expediently be 1/3 to 3/4 above the starting temperature in the temperature range from the starting temperature to the operating temperature. It is obvious that a rapid rise in temperature up to values considerably above freezing can be achieved in this way even in very cold weather and cooling of the entire motor vehicle, with the exception of the latent heat store 4, to temperatures in the range of -20 ° Celsius.
  • a coolant flow through the coolant lines 5 can be interrupted until the internal combustion engine 2 has reached its full operating temperature. Only then is the coolant flowing through the coolant lines 5 again released so that the latent heat storage 4 is heated up to the operating temperature again. This ensures that the internal combustion engine 2 quickly reaches its full operating temperature, starting from the mixing temperature.
  • a special coolant pump which can be driven, for example, by the on-board battery, can be inserted into the coolant lines 5.
  • This coolant pump is to be put into operation before starting the internal combustion engine 2 until a heat balance between the latent heat accumulator 4 and the previously cooled internal combustion engine 2 is reached. If the internal combustion engine 2 is then started, this starting process already takes place at the mixing temperature, so that on the one hand the starting process itself is made considerably easier and on the other hand the cold-running phase of the internal combustion engine is avoided until this mixing temperature is reached, as occurs in the starting process explained above, which means that there are additional advantages in terms of fuel consumption, engine oil consumption, wear and pollutant emissions.
  • the usual window defrosting or cabin heating can be put into operation, which delivers effectively heated air at this early point in time.
  • a special heat exchanger 12 shown in dashed lines in FIG. 1 can of course also be arranged in the coolant line 5 which conveys the hot coolant stored or heated in the latent heat accumulator 4 in the direction of the internal combustion engine 2 before or during the starting process of the internal combustion engine 2 .
  • the window defrosting air or cabin heating air can be heated particularly quickly and effectively when the motor vehicle is started up.
  • a magnetic valve can be provided in the coolant line section 5 between the heat exchanger 12 and the internal combustion engine 2 immediately after the heat exchanger 12, through which the internal combustion engine output of the heat exchanger 12 can be shut off from the internal combustion engine 2 and connected to the coolant line 5 returning to the latent heat store 4.
  • the latent heat store 4 occupies a considerable volume of the trunk 3.
  • the still free volume of the trunk 3 is sufficient during many trips, for example trips to the workplace, to events, excursions or short trips.
  • the counter-couplings 9 are uncoupled from the valve couplings 6 and 7 of the latent heat accumulator 4 and, depending on the design of the coolant circuit, leave separately or coupled together.
  • the self-closing valves in the mating couplings 9 and the valve couplings 6 and 7 prevent coolant from escaping from the coolant lines 5 or the latent heat accumulator 4.
  • the latent heat store 4 can be parked at a suitable location, for example in a garage or a basement.
  • the entire trunk volume 3 of the motor vehicle 1 is now available and can be used accordingly.
  • the advantages offered by the latent heat storage 4 must be dispensed with here, unless the internal combustion engine 2 was started before the start of the dismantling process of the latent heat storage 4.
  • the latent heat accumulator 4 can be re-installed in the trunk 3 after the journeys that require the entire trunk volume have been completed, for example, to be fastened by means of the tensioning straps and to be classified into the coolant circuit by means of the valve couplings 6 and 7 and counter-couplings 9.
  • the latent heat store 4 can be arranged in a different way from FIG. 1 at other suitable locations on the motor vehicle, it does not have to be mounted in the trunk 3. It is conceivable, for example, that it is removably mounted in a space section of the motor vehicle cabin that is only rarely used, in the loading space of a transporter or in another place.
  • the latent heat store 4 In order to facilitate the handling of the latent heat store 4, it can be divided into several individual latent heat stores, hereinafter referred to as individual stores, in a departure from the illustration according to FIG.
  • the individual stores can be designed as disks cut out from the latent heat store 4 according to FIG. it is only necessary to provide each individual store with a handle. This results in addition to Advantages described above the advantage that after separating the individual memories, they are relatively small and light and are accordingly easy to handle.
  • the assembly and disassembly as well as the transport of the latent heat storage is made much easier by this subdivision.
  • the subdivision of the latent heat store 4 into separate individual stores offers the possibility of switching these individual stores on to one another in series or in parallel and in this case in any combination in the coolant circuit. This makes it possible to achieve different compensation temperatures in the individual stores when heat is emitted from the latent heat store, as a result of which a particularly high compensation temperature can be achieved in the internal combustion engine 2 or heat exchanger 12.
  • the latent heat store 4 or at least one of the individual stores can contain an electrical heating cartridge which can be connected to a domestic power supply. After a long period of non-use, the heated latent heat store or individual store can be heated by means of this heating cartridge when it is installed in the vehicle or - mostly - when it is removed and parked in the garage or a cellar, whereby the advantages described above can be achieved when the vehicle is started up. Even a new latent heat storage device can be installed in one by means of such a heating cartridge before it is first installed Motor vehicle are heated and thus immediately offers the corresponding advantages.
  • the motor vehicle (1) is equipped with a latent heat exchanger (4) which can be arranged in its coolant circuit.
  • the latent heat store (4) is arranged in the coolant circuit having the coolant lines (5) in an easily separable manner and is easily removable in a space that is usually not otherwise required during the time of use of the motor vehicle, for example the trunk (3) of the motor vehicle (1). If the space of the motor vehicle (1) mentioned is required for other purposes, for example for luggage, the latent heat store (4) can be separated from the coolant circuit in a simple manner by means of manually operable valve couplings and dismantled from the motor vehicle and stored at a suitable location, for example in a garage or a cellar room will.
  • the latent heat store (4) is provided with at least one handle (11) for its simple, manual transport and can be heated up from the domestic power supply by means of a built-in heating cartridge after a long shutdown period.
