Definitions

  • the invention relates to a heat exchanger for at least one heat transport medium, as is used, for example, as a radiator for heating air flowing into the interior of a motor vehicle.
  • the invention furthermore relates to a coolant circuit and to an air treatment device for vehicles using a heat exchanger of this type.
  • Heat exchangers are used, inter alia in motor vehicles, for different tasks.
  • heat exchangers for cooling the engine are used in a further sense, for example as coolant coolers, oil coolers, exhaust gas coolers and charge air coolers.
  • a further customary field of use of heat exchangers in motor vehicles is the controlling of the temperature of the air supplied to the passenger compartment. Use is made here of heat exchangers, for example in the form of evaporators, condensers (or gas coolers), internal heat exchangers and radiators.
  • heat exchangers of this type exist in very different structural forms and types of installation. If at least one at least partially liquid heat transport medium is used in heat exchangers, as is the case, for example in coolant coolers or radiators, the problem may arise of accumulations of air in the heat exchanger which may possibly have a negative effect on the flow rate or the uniform distribution of the heat transport medium in the heat exchanger. This applies in particular in the case of heat exchangers which are installed upright.
  • One possibility is to set up the heat exchanger, for example by means of a flat installation position or a corresponding arrangement of feed and return openings, in such a manner that air accumulating in the heat exchanger can escape from the heat exchanger or, for example when the system is at a standstill, does not accumulate at all.
  • One problem with heat exchangers set up in such a manner is that certain types of installation (such as, for example, an upright installation of the heat exchanger) or certain designs of the supply openings for the heat transport medium are de facto excluded.
  • this is often problematic, since the construction space in the front part of the motor vehicle generally has very constricted dimensions and certain configurations of the heat exchanger are sometimes unavoidable because of the other engine compartment subassemblies.
  • a further solution possibility is to permit a certain degree of accumulations of air in the heat exchanger and to trust that, at a certain flow rate of heat transport medium, the accumulations of gas in the heat exchanger will be carried along by the heat transport medium through the heat exchanger.
  • a problem with this is that, in particular at low flow rates of heat transport medium, the effectiveness of the heat exchanger may be reduced by the accumulation of air both as seen from the aspect of absolute power and from the uniformity of the heat output. The latter, in particular, may lead to thermal distortions and, especially because of the non-uniform distribution of heat to the radiator surface, may be disadvantageous when treating air for the passenger compartment.
  • a further problem is that, because of the accumulations of gas, the radiators have a tendency to form noise, which is disadvantageous especially with components arranged in the vehicle interior (such as, for example, in the case of the radiator of an air-conditioning system).
  • the present invention therefore sets itself the object of developing a heat exchanger with at least one ventilation device in such a manner that the known problems with heat exchangers known from the prior art are at least partially eliminated or at least reduced.
  • the invention makes it the object to propose a heat exchanger which is simple and cost-effective to construct and produce and nevertheless permits as extensive ventilation as possible without an excess amount of undesirable noises occurring.
  • the ventilation device it is preferable also to form the ventilation device at a distance from at least one feed opening in the heat exchanger.
  • a type of additional “ventilation circuit” can be provided especially in the upper part of the radiator, said ventilation circuit running, in particular, through the critical regions of the heat exchanger and, as a result, being able to particularly effectively ventilate the heat exchanger.
  • care has to be taken here to ensure that a relatively low flow rate is selected for this additional ventilation circuit such that the efficiency of the heat exchanger does not substantially decrease.
  • the distance between at least one ventilation device and at least one feed opening and/or between at least one ventilation device and at least one return opening is at least 10 mm, preferably at least 15 mm, particularly preferably at least 20 mm and, in particular, at least 25 mm.
  • the proposed values have proven favorable.
  • other numerical values are also conceivable. In particular—even with other figures occurring in this specification—in the case of (semi-)intervals and discrete values, all of the numerical values are to be regarded as disclosed and usable as desired.
  • At least one feed opening and at least one return opening are arranged adjacent to each other. This can ensure a compact construction and a simple installation, but also particularly effective ventilation.
  • At least one ventilation device is arranged at a distance from the direct connecting section between at least one feed opening and at least one return opening.
  • the ventilation device is arranged as far as possible away from the direct connecting section between feed opening and return opening.
  • the invention can be used particularly advantageously with heat exchangers which are arranged upright and have, advantageously, at least one coolant tank preferably located at the top.
  • heat exchangers of this type accumulations of gas easily occur and, with the use of the present invention, they can be particularly effectively eliminated.
  • a bottom depth deflection is a “deflection” of the heat transport medium taking place at the bottom at depth.
  • the “depth” refers to the throughflow direction of the second fluid, such as, in particular, air to be heated for a vehicle interior.
  • At least one ventilation device is designed in the form of one or more openings.
  • the openings can be configured, in particular, as recesses and are preferably formed in a heat exchanger partition which is customarily present in any case, preferably in an upper region of a partition.
  • the openings can have any desired shape.
  • Recesses which are circular, semicircular, lenticular, square, rectangular, concave, semi-lenticular and/or slot-like (in each case guided horizontally, vertically and/or obliquely) have proven worthwhile. Dimensions of up to 5 mm, preferably 1 to 4 mm, particularly preferably 2 to 3 mm, have proven worthwhile as typical sizes. However, in particular in the case of slots, lengths of 5 to 15 mm, preferably 6 to 12 mm, in particular 8 to 10 mm, may also prove favorable.
  • the openings are a molded configuration which is advantageously formed in a coolant tank, preferably in a coolant tank located at the top of the heat exchanger.
  • the openings are particularly preferably provided in a contact region between partition and coolant tank wall, in particular in a region located at the top of the coolant tank.
  • the opening may also be located in the region of an optionally present connecting seam of the coolant tank.
  • a further advantageous constructional form can be produced if at least one ventilation device has at least one flow-limiting means which is designed, in particular, as a baffle, as a tube, as an integrally formed flange and/or as a hydrodynamic flow-limiting means.
  • the proposed radiators at least in regions in which accumulations of gas may occur, should not, as far as possible, have any sharp edges and other constructional geometries which may lead to undesirable noises.
  • the proposed development can also make it possible to reduce the noises further by it being possible for the flows which occur to be reduced in particular in terms of velocity and/or flow rate.
  • a hydrodynamic flow-limiting means is understood quite generally as meaning means in which a hydrodynamic banking-up pressure of the heat transport medium flowing through the heat exchanger is used in order to limit other flow paths, in particular of the material flowing through the ventilation devices.
  • At least one ventilation device as an external ventilation device outside the heat exchanger body and/or the coolant tank.
  • the ventilation device here can be arranged, for example, as far as possible away from the passenger compartment or in regions in which only few noises occur or the noises which occur are transmitted only to a reduced extent into the motor vehicle interior.
  • flange region which is optionally formed separately.
  • Said flange region can be provided in the feed or return line, for example at a certain distance from the heat exchanger.
  • this distance between flange and radiator—and therefore the distance of the ventilation device from the radiator— is generally relatively small, and is customarily 10-50 mm, for example 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm or 50 mm.
  • the coolant circuit has the corresponding advantages in analogous form.
  • the air treatment device for motor vehicles with at least one heat exchanger in accordance with one of the abovementioned embodiments.
  • the air treatment device which can additionally have, for example, an evaporator for cooling inflowing air, then has the described advantages in analogous form.
  • a heat exchanger, a coolant circuit or an air treatment device according to one of the above-described embodiment possibilities to the effect that at least one ventilation device is formed with respect to at least one subassembly of the heat transport medium circuit and/or with respect to the entire heat transport medium circuit in the region of a location which is mounted at a geodetically locally high point and/or essentially in the region of the location mounted at the geodetically highest point.

  • the flow cross section for the coolant flowing through in the front region 7 of the upper coolant tank 4 may firstly be constricted for the coolant flowing through, and therefore the heating power of the radiator 1 can decrease.
  • a different distribution of heat along the radiator surface 20 may occur, which accordingly leads to different heating of the air A flowing through, which is correspondingly disadvantageous.
  • FIG. 4 A plurality of suitable partitions 6 which are provided with corresponding ventilation devices are illustrated in FIG. 4 .
  • FIG. 4A illustrates a partition 6 which is of continuous design and can be used, for example, in conjunction with an external ventilation device 21 (see FIG. 8 ).

Even if the figures each only illustrate a single recess 22 , it is also possible for a plurality of recesses which are preferably arranged along the upper edge of the partition 6 to be provided. Diameters of 1, 2, 3 or 4 mm (round or half-round) or 1, 2 or 3 mm for the shorter axis and 2, 3, 4 mm for the longer axis (oval or semi-oval) are appropriate typical dimensions.

  • the baffle 23 in particular if it is arranged in the rear region 8 of the upper coolant tank 4 , can also use a hydrodynamic back pressure. The latter is produced by the flow which emerges from the flat tubes 11 and is indicated by an arrow E.
  • An advantage of said flow E is that it depends on the flow rate of coolant through the radiator 1 .
  • a relatively high difference in pressure is produced between feed 9 and return 10 and therefore between front part 7 and rear part 8 of the upper coolant tank 4 , which would result in a correspondingly high flow rate through the recess 22 .
  • This high flow rate can be reduced by the hydrodynamic effect described.
  • the flow rate through the recess 22 can be reduced with the aid of the baffle 23 and therefore, in particular, the velocity of gas and/or coolant passing through can be reduced. This may, in particular, have a noise-reducing effect.
  • FIG. 6A , 6 B illustrate a further flow-limiting device in the form of a flange or projection 26 , at the lower end 27 of which a ventilation device 28 is formed. Advantages can also arise here, in particular on account of the above-described hydrodynamic effect which may occur. Furthermore, the projection 26 can optionally be produced in a particularly simple and cost-effective manner by shaping the material of the partition 6 by deformation.
  • FIG. 7 shows a further conceivable embodiment of a flow-limiting device in the form of a tube 29 provided with a centrally arranged recess (not visible in the figure).
  • the tube 29 is bent in the form of a “twisted S”, and therefore the entry 31 of the tube 29 runs horizontally, while by contrast the exit 32 of the tube 29 runs vertically, such that hydrodynamic effects can be used particularly advantageously.
