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.

Abstract

The invention provides a movable type automobile air conditioner evaporator with a sufficient refrigerating effect. The movable type automobile air conditioner evaporator comprises a flow collecting pipe system, an evaporation heat exchange device, a fin movement device and a control system, wherein the flow collecting pipe system is vertically arranged; the evaporation heat exchange device is arranged in the middle part of the flow collecting pipe system, and is provided with flat pipes, a louver fin I, a louver fin II, an auxiliary heat exchange cavity and a wiping block; the flat pipes aretransversely arranged, and are connected with the flow collecting pipe system; the adjacent louver fin I and louver fin II are slantwise arranged between the adjacent flat pipes in a V shape; the auxiliary heat exchange cavity and the wiping block are arranged on the louver fin I and the louver fin II; the fin movement device is connected with the flat pipes; a crossing pipe is arranged at the side surface of the flow collecting pipe system. The movable type automobile air conditioner evaporator has the advantages that the automation degree is high, and the functions are simple and practical;by arranging the movable scraping and wiping functions, the condensate and dirt on the louver fin I and the louver fin II can be cleaned, so as to improve the heat exchange efficiency.

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 with sufficient refrigeration. 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 resis...
