Abstract

This invention relates to a parallel evaporator for vehicle air conditioner. It includes integral type fin flat-tube, fin, multi-holes flat-tube, upper collecting pipe, lower collecting pipe, baffle, inlet pipe and outlet opening. Several parallel and communicated integral type fin flat-tubes are composed of multi-holes flat-tubes and fins. The multi-holes flat-tube and fin are emerged together. The superior end of flat-tube connects to the upper collecting pipe. It inferior end connects to the lower collecting pipe. The upper collecting pipe is divided into fluid inlet-outlet cavity and fluid turning cavity by inner baffle. The fluid inlet-outlet cavity is divided into fluid inlet and outlet cavities by inner baffle. The right side of fluid inlet cavity has inlet pipe. The left side of fluid outlet cavity has outlet pipe. The lower collecting pipe is divided into left and right fluid turning cavities by inner baffle. This invention increases the integral heat transferring efficiency and anti-shock capacity of the parallel fluid evaporator. It also reduces the output air temperature difference of each point at the air output side.

Description

[Technical Field] [0001] The invention relates to a parallel flow evaporator for automobile air conditioners, in particular to a structure and flow arrangement form of a parallel flow evaporator for automobile air conditioners. [Background technique] [0002] The automobile air conditioning system is one of the important accessories of the automobile that meets the comfort and driving safety of the passengers in the car. The evaporator is one of the important components in the automobile air conditioning system, its heat exchange effect will directly affect the performance of the entire system, and its weight and size will also affect the compactness of the vehicle. In order to improve the heat exchange efficiency of the vehicle air conditioner evaporator and reduce the space required for its installation, its structure has been developed from the finned tube type and the tube belt type to the stacked type and parallel flow type. The stacked evaporator is a U-shaped plate heat ex...
