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

[0027] As shown in the accompanying drawings of the description, a movable automobile air-conditioning evaporator includes a header system 1, an evaporation heat exchange device 2, a fin movable device 3 and a control system; the header system 1 is placed vertically, and the side A liquid inlet pipe 4 and a liquid outlet pipe 5 are provided; the evaporation heat exchange device 2 includes a flat pipe 6, a louver fin I7, a louver fin II 8, a port 9, an auxiliary heat exchange chamber 10, a wiper block 11, and a movable connection Block 12, track I13, movable button 14, port movable cover 19, limit button I21, limit button II22, push-pull spring chamber 25, push-pull spring 26, dial ball 27, fulcrum buckle 28 and drainage groove 35; The flat tubes 6 are placed horizontally in the middle of the header system 1; the louver fins I7 are inclined to the right, and the louver fins II8 are inclined to the left, forming a "V"-shaped arrangement and arranged on two adjacent flat tubes 6;...

Embodiment 2

[0034] 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

[0036] 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 movable automobile air conditioner evaporator. The movable automobile air conditioner evaporator comprises collecting pipe systems, an evaporating heat exchange device, fin moving devices and a control system; the collecting pipe systems are vertically arranged; the evaporating heat exchange device is arranged between the collecting pipe systems and provided with flat pipes, louver fins I, louver fins II, auxiliary heat exchange cavities and scraping blocks; the flat pipes are transversely arranged and connected to the collecting pipe systems; every adjacent louver finI and louver fin II are obliquely arranged in a 'V' shape between the corresponding adjacent flat pipes; the auxiliary heat exchange cavities and the scraping blocks are arranged on the louver fins Iand the louver fins II; the fin moving devices are connected to the flat pipes. The movable automobile air conditioner evaporator has the advantages that the automation degree is high, the function is simple and practical, and the fin moving devices drive the louver fins I and the louver fins II to scrape one another, thereby being capable of effectively removing condensed water and dirt on the evaporator, and being suitable for the installation and use of the parallel flow evaporator in a current automobile air conditioner..

Description

technical field [0001] The invention belongs to the technical field of automobile air conditioners, and in particular relates to a movable type 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...
