Definitions
- Heat exchanger block and a method for wetting a heat exchanger block
- the invention relates to a heat exchanger block and to a method for wetting a heat exchanger block according to the preamble of the independent claims 1 and 13.
- Heat exchangers are used in refrigerators, e.g. in ordinary
- the laminated heat exchangers serve, like all types of heat exchangers, to transfer heat between two media, for example, but not only, to transfer from a cooling medium to air or vice versa, as is known, for example, from a classic household refrigerator in which heat is released to the ambient air via the heat exchanger for generating a cooling capacity in the interior of the refrigerator.
- the ambient medium outside the heat exchanger e.g. Water, oil or often simply the ambient air, which absorbs heat or transfers heat to the heat exchanger, for example, is either cooled or heated accordingly.
- the second medium may e.g. be a liquid refrigerant or heat transfer or a vaporizing or condensing refrigerant.
- the surrounding medium e.g. the air, a much lower heat transfer coefficient than the second medium, e.g. the coolant used in the
- Heat exchanger system circulates. This is compensated by greatly different heat transfer surfaces for the two media:
- the medium with the high heat transfer coefficient flows in the tube, which on the outside by thin sheets (ribs, fins) has a greatly enlarged surface at which the heat transfer, for. takes place with the air.
- Fig. 1 shows a simple example of such a known laminated heat exchanger 41 '.
- such a laminated heat exchanger 41 'by a plurality of cooling fins 413' is formed, whereby the heat exchange surface T can be massively increased.
- the cooling means 6 ' In the operating state flows through the coolant lines 411 'a heating means 6', so that the heating means 6 'mainly via the cooling fins 413' with the environment, usually with the ambient air 5 'can exchange heat by the ambient air 5' as Transportfluidum 5 'for transport the heat, for example, by means of a fan in the direction of the arrow 5 'according to FIG. 1 by the heat exchanger 41' is transported.
- the lamellar spacing is chosen differently for different applications. However, purely thermodynamically, it should be as small as possible, but not so small that the air-side pressure loss is too large. An economic optimum is about 2 mm, which is a typical value for condenser and recooler.
- FIG. 2 To illustrate the construction of the heat exchanger 41 'according to FIG. 1, a detail of a plan view from direction R to the heat exchanger is shown schematically in FIG. 2. Particularly important are the collar 414 ', through which the coolant lines 411' are guided, since this ensures that the cooling fins 413 'comply with a defined distance d'.
- the efficiency is essentially determined by the fact that the heat that is transferred between the fin surface and the air, must be transmitted through heat conduction through the fins to the pipe. This heat transfer is all the more effective, the higher the conductivity or the thickness of the lamella, but also the smaller the distance between the tubes. This is called the lamella efficiency.
- As a lamellar material is therefore nowadays predominantly aluminum used, which has a high thermal conductivity (about 220 W / mK) to economic conditions.
- the pipe pitch should be as small as possible, but this leads to the problem that you need many pipes.
- Many pipes mean high costs because the pipes (usually made of copper) are considerably more expensive than the thin aluminum fins.
- minichannel or microchannel heat exchangers have been developed, which are manufactured according to a completely different process and almost correspond to the ideal of a laminated heat exchanger: many small tubes with small spacings.
- the microchannel heat exchanger employs extruded aluminum sections which have very many small channels with a diameter of e.g. about 1 mm.
- the MicroChannel heat exchanger block 1 'of Fig. 3 is formed by two known per se heat exchanger 42' in the form of extruded profiles 42 '.
- the two extruded profiles 42 'of FIG. 3 are preferably in thermal contact with a corrugated cooling fin 413', so that the heat medium 6 'carried by the microchannels 421' will be heat with the transport fluid 5 ', preferably air 5'. which, for example, with a fan, not shown in the direction of the arrows 5 'is transported through the heat exchanger block 1', can exchange better.
- a heat exchanger block 1 ' In practice, a heat exchanger block 1 ', depending on the required heat output, already manage with a single extruded profile 42' as a central heat exchange element.
- a plurality of extruded profiles 42 ' can also be provided simultaneously in a single heat exchanger block 1', which are connected to each other in suitable combinations, for example via and to each other, for example with each other are soldered, which is not shown for reasons of clarity in Fig. 3.
- extruded profiles may e.g. be made easily and in a variety of forms from a variety of materials in suitable extrusion.
- other methods of making microchannel heat exchangers are known, such as e.g. the assembly of suitably shaped profile sheets or other suitable methods.
- Microchannel heat exchangers have become established in mobile use during the 90s.
- the low weight, the low block depth and the limited dimensions required here are the ideal ones
- Car radiator and condenser and evaporator for Automobile air conditioning systems are today almost exclusively realized with mini-channel heat exchangers.
- This method has numerous problems in practice and is in little demand by the customer for a variety of reasons.
- cooling water can not be effectively transferred to the entire heat exchange surface of the heat exchanger.
- targeted application of cooling water is indicated in many applications. For example, in a condenser in which the upper part is used as a heater to take into account that this upper part must not be wetted because of the high temperatures occurring.
- the object of the invention is therefore to provide an improved heat exchanger block, in particular hybrid heat exchanger, which overcomes the problems known from the prior art.
- the invention thus relates to a heat exchanger block comprising a heat exchanger arranged between an inflow surface and an outflow surface, such that heat exchange between a transport fluid and a heat medium flowing through the heat exchanger in the operating state, the transport fluid can be fed via the inflow surface of a heat exchange surface of the heat exchanger, with the heat exchange surface can be brought into flowing contact, and over the Outflow of the heat exchanger is weg1700bar again.
- a perforated coolant lance is provided, so that a coolant can be introduced via the coolant lance between two heat exchange surfaces of the heat exchanger.
- Heat exchange between heat exchanger and transport fluid, e.g. between the heat exchanger and air, which is passed through the heat exchanger, can be significantly improved by a coolant, which is preferably but not necessarily water, via a coolant lance directly into the interior of the heat exchanger on the
- Heat exchanging surfaces is spent in the heat exchanger.
- a perforated tube or a perforated or porous tube is provided on the heat exchanger block, with which the coolant between two heat exchange surfaces of the heat exchanger can be introduced.
- the heat exchange surfaces of the heat exchanger can be wetted in a targeted and controlled manner with coolant.
- coolant Depending on how the refrigerant lances are placed in the heat exchanger, thus, for example, over the entire heat exchanger, a very uniform cooling performance can be adjusted.
- a non-uniform distribution of the cooling capacity in the heat exchanger block can also be achieved by other measures become. It is thus possible, for example, for different coolant lances to be used in different regions of the heat exchanger block, which supply different amounts of coolant to the different regions.
- the different coolant lances may have different perforations, eg have different large perforations or holes through which the coolant is introduced between the two heat exchange surfaces.
- the cooling capacity in a heat exchanger block according to the invention can be controlled and / or regulated simply and efficiently, for example by controlling the working pressure of the coolant as a function of time and / or as a function of location in all or in certain coolant lances / or regulated.
- the coolant lances Since the coolant is brought into the heat exchanger in the place where it is needed immediately, it can be very easily and efficiently dosed, and it does not need to be worked in particular with multiple excess water. In many cases, therefore, eliminates a drip pan, since no excess water is obtained in the operating condition. As a result, the formation of polluted aerosols is substantially prevented and valuable coolant saved. Even the time-consuming cleaning of excess cooling water is eliminated.
- the wetting method proposed by the present invention is thus that, for example, in a laminated heat exchanger, replacing a first row of tubes in the direction of air by refrigerant lances in the form of tubes or porous tubes provided with small holes or nozzles making up the Wetting water, so the coolant exits and is introduced into the disk pack. So that the wetting water can be distributed well on the surfaces of the lamellae, the perforation of the first row of tubes of the lamellae or collar, that is executed without spacers.
- the pipes or hoses used as coolant lances are preferably not expanded or otherwise fixed, but are loosely inserted.
- a row of tubes, in particular a first row of tubes of the plate pack of the air-cooled heat exchanger can be provided for example partially or completely with coolant lances. Partial assembly is, as already mentioned, particularly useful if the heat exchanger is used as a condenser and the upper part of the same as a heater, which must not be wetted with coolant because of the high temperatures.
- the regulation of the amount of coolant can be done, if necessary, for example, via the working pressure of the coolant. It is understood that, instead of just equipping the first row of pipes with coolant lances, the coolant lances can also be placed in any meaningful arrangement in the disk pack and can be provided with appropriate perforations.
- filter hoses can also be used, sometimes called sweating hoses, which clean the coolant, ie for example the wetting water, wherein the degree of purity of the filtered coolant depends on the quality of the filter hose.
- the hoses can also be cleaned by rinsing off the filtrate.
- coolant or wetting liquids are used instead of ordinary water, e.g. demineralized or distilled water or otherwise specially modified water or, in very special cases, other refrigerants known to those skilled in the art.
- Microchannel heat exchanger can be inserted. If the refrigerant lances configured as flat tubes work together with the MPE tubes soldered, there would be the danger that the holes of the slits of the flat tube would close with solder and thus would no longer be available for the wetting with coolant.
- the heat exchanger is designed as a laminated heat exchanger, wherein a coolant line is provided in a punched-out cooling plate.
- the coolant lance is provided in a separate bore in the cooling lamella, so that the number of coolant lines is not reduced by the introduction of the coolant lance. It is of course also possible that a coolant line is removed and the coolant lance is provided in the punched-out of the cooling fins.
- the heat exchanger is formed by a multiplicity of microchannels as a microchannel heat exchanger.
- the coolant lance is preferably a tube perforated in the form of holes and / or slots, and is provided in particular in the form of a flat tube.
- a filter hose may be provided as the coolant lance, so that the coolant is automatically cleaned of certain impurities before it is applied to the heat exchange surface.
- a heat exchanger block according to the invention may be formed as a combination block of the laminated heat exchanger and the microchannel heat exchanger. This may be the case, for example, if different conditions prevail at different locations with one and the same heat exchanger block and / or different heat outputs must be provided.
- a cooling device for cooling the heat exchanger in particular a fan for generating or amplifying a gas flow of the transport fluid, may additionally be provided.
- a known control unit for controlling and / or regulating the heat exchanger block, advantageously a known control unit, in particular a control unit with a data processing system for controlling a cooling machine and / or a cooling device and / or the supply of the coolant via the coolant lance and / or an operating or state parameter the heating means and / or another operating parameter of the heat exchanger block may be provided.
- the heat exchanger and / or the entire heat exchanger block made of a metal and / or a metal alloy, in particular of a single metal or a single metal alloy, in particular stainless steel, in particular aluminum or made of a metal alloy, and / or made of a metal combination, for example of aluminum and copper, wherein a sacrificial metal is preferably provided as corrosion protection, and / or wherein the heat exchanger block is at least partially provided with a protective layer, in particular with a corrosion protection layer.
- a heat exchanger block according to the invention may e.g. is a cooler, a condenser or an evaporator for a mobile or stationary heating system, cooling system or air conditioning, in particular a cooler device for a machine, a data processing system or for a building.
- the invention further relates to a method for wetting a heat exchanger block comprising a heat exchanger arranged between an inflow surface and an outflow surface so that the transport fluid is supplied via the inflow surface to a heat exchange surface of the heat exchanger for exchanging heat between a transport fluid and a heat medium flowing through the heat exchanger Heat exchange surface is brought into flowing contact, and is led away over the discharge surface of the heat exchanger again.
- a perforated coolant lance is provided on the heat exchanger block, and a coolant is introduced via the coolant lance between two heat exchange surfaces of the heat exchanger.
- the heat exchanger is a laminated heat exchanger and / or a microchannel heat exchanger, and a regulation of a wetting amount of the coolant is made, and is preferably carried out by adjusting a working pressure of the coolant.
