[0001] The present application relates to the technical field of automobile air conditioner evaporator, in particular to high-efficiency automobile evaporator. BACKGROUND

[0002] The function of automobile evaporator is generally to cool the high-temperature and high-pressure refrigerant vapor discharged by compressor, so that it is condensed into high-pressure refrigerant liquid; the refrigerant changes from liquid state to gaseous state (i.e. evaporates), absorbs a large amount of heat around, and then the low-temperature and low-pressure refrigerant vapor enters the compressor; the process is repeated to achieve the purpose of low temperature, providing a comfortable driving environment for passengers in summer, reducing the fatigue intensity of the driver, and improving the driving safety.

[0003] The existing automobile evaporator is generally composed of a box, a pipe and a fin. The pipe and the fin are usually welded and fixed in the traditional evaporator, and the pipe and the fin are connected internally to increase the heat exchange efficiency, so that the position of the fin is fixed and the size of the ventilation and heat dissipation gap cannot be effectively changed, which is not conducive to heat dissipation and adjustment.

[0004] Therefore, we propose a high-efficiency automobile evaporator. SUMMARY

[0010] Preferably, the communication assembly further comprises a gear fixedly connected with the middle part of the U-shaped pipe, a limiting sleeve fixedly connected with the telescopic heat dissipation cylinder, a toothed plate slidingly matched with the gear in the limiting sleeve, and a pressing frame made of rubber and fixedly connected with one end of the toothed plate and abutting against the telescopic heat dissipation cylinder.

[0012] Preferably, the wiping assembly comprises a plurality of pressing rods in an inclined distribution, the pressing rods are rotationally connected with the movable rod through torsional springs, and wiping rods are fixedly connected with the end portions of the pressing rods and movably matched with the telescopic heat dissipation cylinder.

[0014] Preferably, the movable rod is in a rectangular structure in cross section, and the movable rod slides in the limiting frame to avoid self-rotation of the movable rod.

[0015] Compared with the prior art, the present application has the following beneficial effects:

[0018] When the automobile air conditioner stops working, the telescopic heat dissipation cylinder is controlled to reset by the motor, so that the wiping rods wipe the surface of the telescopic heat dissipation cylinder again, and the leeward surface of the telescopic heat dissipation cylinder is prevented from being prone to mildew and peculiar smell due to moisture not being wiped dry for a long time.
