Definitions
- the present invention relates to a coolant pump according to the preamble of claim 1 and a method therefor according to the preamble of claim 22.
- a short circuit or bypass circuit is provided in modern internal combustion engines, with which heated coolant coming from the engine can be returned directly to the engine via the coolant pump.
- the warm-up phase of the engine is shortened during a cold start, the cylinder tube is warmed up quickly after the cold start, and the tribologically optimal temperature can be regulated.
- the coolant pumps have built-in electronic as well as electrical components, such as the electric motor that drives the pump impeller or the electronic components, sensors, converters or control loops that allow control and / or regulation of the engine speed, the pump power, the valve position or other functions have a limited temperature tolerance and are therefore not subject to unlimited high temperatures.
- Components that are affordable at a reasonable price, approved in motor vehicle construction and available in sufficient quantities can sometimes only be operated at a maximum of up to 120 ° C. This threatens the rapid heat death of such electrical and / or electronic components.
- the pump motor and the pump shaft are arranged coaxially to the longitudinal axis of the pump housing.
- the pump shaft is arranged coaxially to the longitudinal axis of the pump motor, but this assembly is arranged asymmetrically or eccentrically in the pump housing, which may lead to cost advantages in the manufacture of the housing.
- the concentric or coaxial variant is preferred, since it is much simpler to build, easier to implement due to the symmetries, and offers the greatest advantages in terms of flow technology and is probably the cheapest solution in terms of cost.
- the flow channel which is delimited by the outer wall of the motor housing comprising the pump motor and the facing inner wall of the pump housing, has an annular cross section.
- coolant which can be sucked in by the cooler through the inlet, can be guided past the pump motor in a jacket flow that surrounds the motor housing in a ring.
- the heat generated by the electric motor is advantageously dissipated uniformly all around. A point or partial surface heating or so-called "hot spots" are thus excluded. This ensures permanent, reliable operation at temperatures that are compatible with the pump motor.
- the plastic pump housing and the valve slide can be manufactured particularly cheaply, for example, using the plastic injection molding process. Post-processing of these components is advantageously not necessary.
- coolant pump according to the invention offers the further advantage that a low priming delivery rate is already required to achieve a desired RieljJr throughput is sufficient. This means that pump motors with low electrical power consumption can also be used.
- the coolant pump according to the invention has the further advantage that, when the valve is in the "cooler open” position, there is no reduction in the maximum delivery cross section, so that for this reason too, a low delivery rate is sufficient for the circulation of the coolant, so that the electric pump therefore also has an im Compared to commercially available electric pumps, lower power consumption can be produced.
- valve spool designed as a cylindrical sleeve is its relatively simple kinematics, so that a switching movement in the longitudinal direction can be implemented without problems.
- This offers the further advantage that a continuous mixture of bypass and inlet can be realized by a simple linear movement, namely a longitudinal displacement, so that there is a direct, in particular linear, connection between the valve position or orifice opening and the mixing ratio and the current position of the valve spool , which can be mapped easily and without any special effort.
- Expansion element is made of wax. Its melting point is around 85 ° C. Its temperature-dependent change in volume can then be done via a separate
- the CPU or control unit of the pump can issue commands or voltage signals to the coil carrier and the pump motor, so that the desired or required valve position is continuously adjusted and an interrogated engine speed is recorded.
- a correspondingly miniaturized or adapted variant of the slide valve can be used to control the return flow from a heater, a transmission oil heat exchanger or the like.
- the control unit ensures that the valve is briefly switched to the "cooler inlet open” and “bypass closed” positions, the coolant present flows briefly and then the valve is returned to its original position, so that fresh, completely cooled cooling medium from the cooler then encloses and cools the electric pump. Accordingly, even in the case of a cold start and the switch position “bypass open” which is present for some time and which is selected in order to keep the warm-up phase of the motor vehicle internal combustion engine as short as possible, there is no fear of endangering the electronic components. Due to the sliding seat valve variant, all mixtures are possible. The slide seat valve can be infinitely adjusted. There are no movement gaps that would be difficult to seal.
- the electromagnet is opposite the valve sleeve with rod seals
- the housing of the pump motor can be made of metal, for example aluminum or another noble metal that is particularly good heat conductor. This ensures optimal heat dissipation from the electrically operated pump motor to the coolant flowing around it.
- Fig. 6 is a 3D view of the pump shown in Figs. 2 to 5;
- the electrical coolant pump 1 with an integrated directional valve shown schematically in simplified form with a symbol in FIG. 1, is further explained in detail in different variants in FIGS. 2 to 8.
- 2 shows a first exemplary embodiment of a coolant pump 1 in longitudinal section.
- the coolant pump housing 14 is divided into two in this embodiment. It consists of a first housing part 16 and a second housing part 18. Both housing parts 16 and 18 are firmly connected to each other with a ring-shaped clip, clamp or clip 20, tightly closing.
- the housing 14 can also be made in three or more parts or also in one part with a cover.
- valve slide 72 is also used as the armature 74 of an electro-actuating magnet 76 which actuates the valve slide 72.
- the valve slide 72 is on its radially outer side by means of Rod seals 77 performed with Abslxeifrfunktion and sealed against the housing 14 or against the other neighboring components.
- the electric actuating magnet 76 has the aforementioned armature 74 and a coil carrier 78 which is arranged in the pump housing 14 and which surrounds the armature 74.
- the armature 74 is formed by the cylindrical sleeve 72 so that it is made of metal.
- the sleeve 72 can also be made of plastic and have metallic sections forming the armature 74.
- the associated coil 80 is arranged on the coil carrier 78.
- the coil 80 is in turn surrounded by an iron yoke 82 arranged radially outside the coil 80.
- an annular iron yoke 84 Radially inside, an annular iron yoke 84, which is arranged between the coil carrier 78 and the armature 74 and is designed in an annular manner and influences the characteristic curve, is integrated.
- the rod seals 77 are also arranged between the coil carrier 78 and the valve slide 72 designed as an armature 74, a rod seal 77 directly adjoining the iron yoke
- FIG. 6 The exemplary embodiment of a coolant pump 1 shown in FIGS. 2 to 5 is illustrated in FIG. 6 in a three-dimensional view for a better understanding of the spatial assignment of the nozzles or the components.
- Pump impeller 32 in addition to the coolant electric motor 26 via a drive wheel 106 arranged outside the pump housing 14.
- the drive wheel 106 is aligned coaxially with the pump shaft 30 and can be mechanically coupled to the pump shaft 30 via a freewheel 108.
- the pump shaft 30 has an additional ches bearing 110 in the right end of the housing part 18 in this illustration.
- the pump impeller 32 can be driven in addition to the electric motor 26 from the outside, for example via a belt or a pinion.
- the coolant pump 1 can thus be driven primarily mechanically via the drive wheel 106, which is designed, for example, as a belt wheel.
- the drive wheel 106 is decoupled from the pump shaft 30 via the freewheel 110.
- FIG. 8 The variant of the coolant pump 1 shown in longitudinal section in FIG. 7 is illustrated in FIG. 8 in a three-dimensional view for better understanding of the spatial assignment of the components.
- FIGS. 9 to 11 A further variant of a coolant pump 1 is shown in FIGS. 9 to 11.
- the further variant of a coolant pump 1 shown in FIG. 9 in longitudinal section and in FIG. 10 in an enlarged detail and in FIG. 11 in a three-dimensional view from the outside corresponds essentially to the coolant pump 1 discussed in FIGS. 1 to 6 or equivalent
- FIGS. 9 to 11 The exemplary modifications shown in FIGS. 9 to 11 with regard to the drive of the directional control valve 40, which is explained in more detail here, via an expansion element 112 can also be correspondingly transferred to the coolant pump variants shown in FIGS. 1 to 6 and to FIGS. 7 and 8.
- the alternative shown in FIGS. 9 to 11 of driving the directional valve 40 via an expansion element 112 uses the change in volume of the expansion element 112 as a function of the temperature of the coolant mixture flowing through it in the pressure port 34.
- wax is used as the expansion element 112, for example.
- the wax used here has a melting point of around 85 ° C.
- the wax is present as a wax element 112 solidified in the cold state.
- the coil spring 73 shown in the embodiments according to FIGS. 1 to 8, which is provided there to guarantee a fail-safe position of the directional valve 40. can be seen is now used in the directional control valve variant shown here to achieve a closing function and is no longer used to generate a fail-safe position.
- the valve slide 72 is in the relaxed state of the spring 127 in a “bypass open” or “cooler inlet closed” position. Heating the expansion element 112 made of wax and the resulting volume expansion of the wax accordingly leads to a curvature of the membrane 116 and thus to a change in the volume of the storage container 118, which ultimately results in a shift of coolant 120 from the storage container 118 into the cylinder space 126 results.
- the cooling and / or heating elements are assigned to the expansion element 112, which are not shown here.
- the volume can be actively expansion of the expansion element 112 can be influenced in order, if necessary, to set different control states of the directional control valve 40 than those which would arise on their own.
- the coolant 120 can be introduced into the storage chamber 118 or into the system through a filling opening 130 which can be closed with a screw plug 128.
- the expansion element 112 made of wax is so dimensionally stable in the cold state that it can be installed as a finished component when the pump 1 is assembled. Sealing rings 132 or the like serve to seal the valve slide 72 against the housing 14.
- FIG. 10 shows particularly clearly how the spring 127 forms a pair of forces with the expansion element 112 via the transmission medium 120 and generates a permanent counterforce to the expansion element 112.
- Commercial expansion wax can be used for the expansion element 112.
- the transmission medium or coolant 120 can be a water / glycol mixture.
- the hydraulic system 134 formed from the storage space 118 filled with coolant 120, connecting lines 122 and 124 and cylinder space 126 is filled with excess pressure without bubbles when the coolant pump 1 is installed.
- the wax element 112 made of wax is inserted into the housing 14 during the assembly of the pump 1, specifically in the space 136 by the metallic cylinder jacket 114, which limits the radial play of the impeller 32 and the inner wall of the elastomer membrane 116, is therefore hermetically delimited.
- the wax has a melting point of approx. 85 ° C.
- the wax 112 can be influenced via a heating and / or cooling element.
- the variant of the coolant pump 1 shown in longitudinal section in FIG. 9 and in enlarged partial section in FIG. 10 is illustrated in FIG. 11 in a three-dimensional view for a better understanding of the spatial assignment of the components.
- the design of the wax element is tailored to the structural conditions of the coolant pump.
- the directional valve, which is ultimately hydraulically driven with the expansion element, advantageously has a similar effect to an electrically controllable thermostat.
- the components of a vehicle that have an impact on consumption and emissions are particularly in the spotlight today.
- a map-controlled thermostat is a component that has a positive influence on fuel consumption and the reduction in emissions. Conventional thermostats are set to a fixed opening temperature that cannot be changed.
- the wax element can optionally be additionally heated or cooled.
- a rod heater not shown, can be used for heating. This takes over the heating of the wax element and is in direct contact with the wax.
- the rod heater can be heated, for example, via a resistance wire wound on a ceramic body.
- the thermostat thus formed can be set unheated, for example, to a temperature of 110 ° C. The temperature can be reduced to approx. 70 ° C, for example, by heating. The full opening temperature is thus reached at 15 ° C above the normal opening temperature.
- the response time of the thermostat can be influenced by the heating power, the immersion depth of the rod heating in the wax element, and the surface design of the wax element. In order to be able to test the aforementioned application in the development phase, the applicant developed electronics.
- the present invention for the first time specifies a coolant pump for a coolant circuit of a motor vehicle internal combustion engine, which has at least one cooler circuit and a bypass circuit.
- the coolant pump housing has a suction connection, a bypass connection and a pressure connection, as well as a coolant pump electric motor arranged in the coolant pump housing, the motor housing of which the coolant flows and which drives a pump impeller via a pump shaft, as well as a directional valve integrated in the coolant pump housing.
- the suction nozzle is arranged for the first time in the region of the end of the pump motor facing away from the pump impeller.
- the bypass nozzle is also arranged in an area downstream of the suction nozzle.
- the pressure port is arranged in an area downstream of the bypass port.
