Problems solved by technology

At present, more advanced automobile air conditioning systems mostly use parallel flow evaporators to improve the heat exchange effect of the evaporators. However, when the parallel flow evaporators work, a large amount of condensed water is often generated, which is attached to the louver fins and flat tubes of the evaporator. A certain resistance is formed, which affects the circulation of the air and also reduces the heat exchange effect between the air and the louver fins
The general parallel flow evaporator is treated with hydrophilic treatment on the surface, and by reducing the contact angle between the liquid droplets and the fins, the condensed water exists in the state of a water film, thereby reducing the resistance of the air side of the evaporator to a certain extent, but This method cannot completely eliminate the influence of condensed water, and its hydrophilic coating is easy to fall off due to the influence of welding high temperature, etc.

Embodiment 1

[0030] As shown in the drawings of the description, a new type of automobile air-conditioning evaporator includes a header system 1, an evaporation heat exchange device 2, a fin movable device 3, a condensed water treatment system 51 and a control system; the header system 1 Placed vertically, the side is provided with a liquid inlet pipe 4 and a liquid outlet pipe 5; the evaporation heat exchange device 2 includes flat pipes 6, louver fins I7, louver fins II8, ports 9, auxiliary heat exchange chambers 10, wipers Block 11, movable connection block 12, track I13, movable buckle 14, port movable cover 19, limit buckle I21, limit buckle II22, push-pull spring cavity 25, push-pull spring 26, dial ball 27, fulcrum buckle 28 and Drainage groove 35; the flat tube 6 is placed horizontally in the middle of the header system 1; the louver fin I7 is inclined to the right, and the louver fin II8 is inclined to the left, forming a "V"-shaped arrangement in the adjacent between the two flat...

Embodiment 2

[0038] The structure and principle of this embodiment 2 are basically the same as that of embodiment 1, the difference is that the evaporation heat exchange device 2 also includes a limiting plate 20; the limiting plate 20 is arranged behind the port movable cover 19; The buckle I 21 is arranged on the limiting plate 20 and faces the movable cover 19 of the port. The function of the limit plate 20 is to support the limit buckle I21 and play the role of limit.

Embodiment 3

[0040] The structure and principle of this embodiment 3 are basically the same as that of embodiment 1, the difference is that the evaporation heat exchange device 2 also includes a roller 23 and a track II 24; the movable cover 19 and the track II 24 are arranged in the flat tube 6; The port movable cover 19 is inserted into the track II 24 through the roller 23 arranged at the bottom. The roller drives the port movable cover to move on the track II.

Abstract

The invention provides a novel vehicle air conditioner evaporator. The novel vehicle air conditioner evaporator comprises a header pipe system, an evaporation heat exchange device, a fin movable device, a condensate water processing system and a control system. The header pipe system is vertically placed. The evaporation heat exchange device is arranged in the middle of the header pipe system andprovided with flat pipes, louvered fins I, louvered fins II, auxiliary heat exchange cavities and wiping blocks. The flat pipes are transversely placed and connected with the header pipe system. Eachlouvered fin I and the adjacent louvered fin II form a V shape and are obliquely arranged between the corresponding adjacent flat pipes. The auxiliary heat exchange cavities and the wiping blocks arearranged on the louvered fins I and the louvered fins II. The fin movable device is connected with the flat pipes. The evaporation heat exchange device is connected with the condensate water processing system. The novel vehicle air conditioner evaporator is high in degree of automation and good in using effect, the vehicle air conditioner evaporator can be automatically cleaned, and the refrigerating effect of a vehicle air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioners, and in particular relates to a novel automobile air conditioner evaporator. Background technique [0002] The automotive air conditioning system is a device that cools, heats, ventilates and purifies the air in the cabin, and is one of the signs to measure whether the car has complete functions. The evaporator is a key component in the automotive air-conditioning unit, and its structure, material properties and manufacturing process affect the working efficiency of the entire air-conditioning system. At present, more advanced automobile air conditioning systems mostly use parallel flow evaporators to improve the heat exchange effect of the evaporators. However, when the parallel flow evaporators work, a large amount of condensed water is often generated, which is attached to the louver fins and flat tubes of the evaporator. A certain resistance is formed, which affects the ci...
