Abstract
The utility model discloses a heat returning device of an automobile air-conditioning, comprising an aluminum cylinder. The aluminum cylinder is provided with a first through hole for evaporator outlet refrigerants to pass and a second through hole for condensate liquid which is discharged from a condenser and flows in a direction opposite to that of the evaporator outlet refrigerants. The first through hole and the second through hole are disposed side by side. The evaporator outlet refrigerants and the condensate liquid discharged from the condenser conduct reverse flow in the first through hole and the second through hole. The low temperature and low pressure refrigeration steam discharged by the evaporator and the high temperature and high pressure condensate liquid discharged by the condenser conduct heat exchange through the aluminum heat returning machine while flowing. Accordingly, heat returning by the refrigerants can be realized, the change of the parameter of the refrigerants in a cycling system can be reduced, and the performance of the automobile air-conditioning can be guaranteed.
Description
Technical field
The utility model relates to air conditioning for automobiles field, is specifically related to a kind of air conditioning for automobiles regenerative apparatus.
Background technology
Automotive air-conditioning system provides the functions such as refrigeration, heating, defrosting and demist for automobile, it has become one of automobile important accessory of car room passenger comfort and drive safety.The performance parameter of cold-producing medium in each parts of air conditioner cooling cycle system directly affects the performance of air-conditioning.Due to the particularity of mounted air conditioner system operation, it is larger that it is affected by vehicle operating, causes cold-producing medium parameter in systemic circulation to change greatly, although adopt the measures such as a series of temperature controls, affects still more violently, and then has influence on heat pump performance.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cold-producing medium parameter in the circulatory system that can effectively reduce to change, and guarantees the air conditioning for automobiles regenerative apparatus of heat pump performance.
To achieve these goals, the technical solution adopted in the utility model is:
This air conditioning for automobiles regenerative apparatus, comprises aluminium cylinder, establishes side by side the first through hole passing through for evaporator outlet cold-producing medium and discharge for the condenser contrary with described evaporator outlet refrigerant flow direction the second through hole that condensate liquid passes through on described aluminium cylinder.
Described the first through-hole aperture is identical with evaporator outlet pipeline aperture, and described the second through-hole aperture is identical with condensator outlet pipeline aperture.
On described aluminium cylinder outer wall, be enclosed with thermal insulation layer.
Described the first through hole and the second through hole two ends are respectively the sealed interface of the use that is tightly connected.
Described aluminium cylinder is cylinder.
Described the first through hole and the second through hole are all arranged on the axially upper of aluminium cylinder, and described the first through hole and the second through hole parallel setting.
The utility model has the advantage of: this air conditioning for automobiles regenerative apparatus, evaporator outlet cold-producing medium and condenser are discharged condensate liquid reverse flow in the first through hole and the second through hole; The HTHP condensate liquid that the low-pressure low-temperature refrigeration steam that evaporimeter is got rid of and condenser are discharged is in mobile, and logical peraluminous regenerator carries out exchange heat, reaches the object of cold-producing medium backheat; And then reduce the variation of cold-producing medium parameter in systemic circulation, guaranteed the performance of air conditioning for automobiles.
Accompanying drawing explanation
The content of below each width accompanying drawing of the utility model description being expressed and the mark in figure are briefly described:
Fig. 1 is the perspective view of the utility model air conditioning for automobiles regenerative apparatus;
Fig. 2 is the sectional view of Fig. 1 air conditioning for automobiles regenerative apparatus;
Mark in above-mentioned figure is:
1, aluminium cylinder, the 2, second through hole, the 3, second through hole.
The specific embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figures 1 and 2, this air conditioning for automobiles regenerative apparatus, comprise aluminium cylinder 1, on aluminium cylinder 1, establish side by side the first through hole 2 passing through for evaporator outlet cold-producing medium and discharge for condenser the second through hole 3 that condensate liquid passes through, evaporator outlet cold-producing medium is discharged condensate stream to contrary with condenser, and the two carries out exchange heat, aluminium good heat-transfer in flow process, gaseous refrigerant is sucked before compressor overheated, liquid refrigerant enters before throttling arrangement excessively cold.
Preferably the first through hole 2 apertures are identical with evaporator outlet pipeline aperture, and the second through hole 3 apertures are identical with condensator outlet pipeline aperture.
On aluminium cylinder 1 outer wall, be enclosed with thermal insulation layer, thermal insulation layer is made by heat-insulating material, further guarantees the effect of cold-producing medium heat exchange.
The first through hole 2 and the second through hole 3 two ends are respectively the sealed interface of the use that is tightly connected, the first through hole 2 and the second through hole 3 two ends be processed into install corresponding radially or the form of end face seal.
Preferably aluminium cylinder 1 is cylinder, and aluminium cylinder 1 is aluminium bar, draws materials easily, and cost of manufacture is low; More being conducive to whole air-conditioning system efficiently moves.
The first through hole 2 and the second through hole 3 are all arranged on the axially upper of aluminium cylinder 1, and preferably the first through hole 2 and the second through hole 3 parallel setting, can guarantee heat transfer effect like this.
This air conditioning for automobiles regenerative apparatus, evaporator outlet cold-producing medium and condenser are discharged condensate liquid in the first through hole 2 and the interior reverse flow of the second through hole 3; The HTHP condensate liquid that the low-pressure low-temperature refrigeration steam that evaporimeter is got rid of and condenser are discharged is in mobile, and logical peraluminous regenerator carries out exchange heat, reaches the object of cold-producing medium backheat; And then reduce the variation of cold-producing medium parameter in systemic circulation, guaranteed the performance of air conditioning for automobiles.
The utility model specific implementation is not subject to the restrictions described above, as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out, all within protection domain of the present utility model.
