Parallel flow evaporator applied to automobile air conditioner

Abstract

The invention discloses a parallel flow evaporator applied to an automobile air conditioner. The parallel flow evaporator comprises a front heat exchange module (1) and a rear heat exchange module (2) which are arranged in parallel; and the front heat exchange module and the rear heat exchange module are each composed of an upper evaporation chamber (3), a lower evaporation chamber (5) and multi-port flat tubes (4) connected with the upper evaporation chamber and the lower evaporation chamber. The parallel flow evaporator is characterized in that partition boards a (6) are arranged at the positions, close to the front portions, of the middles of the upper evaporation chambers (3), and partition boards b (7) are arranged at the positions, close to the rear portions, of the middles of the lower evaporation chambers (5); rear portions divided from the lower evaporation chambers (5) through the partition boards b (7) are provided with flow passing holes, and the rear portions of the lower evaporation chambers (5) of the front heat exchange module and the rear heat exchange module are communicated through the flow passing holes; front space and rear space on the front portion of each upper evaporation chamber (3) serve as an air outlet chamber and a liquid inlet chamber respectively; and the liquid inlet chambers are connected with liquid inlet pipes (8), and the air outlet chambers are connected with air outlet pipes (9). According to the parallel flow evaporator, the six-flow evaporation mode is adopted; the structure is compact, and the heat exchange efficiency is improved; and the efficient cooling aim is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and relates to an automobile air-conditioning evaporator, more specifically, the invention relates to a parallel-flow evaporator applied to an automobile air-conditioning. Background technique [0002] With the rapid development of automobile technology, people have higher and higher requirements for automobile comfort, especially automobile air conditioners; at the same time, automobile manufacturers need to provide more efficient products while meeting customer needs in the fierce market competition. The product. [0003] Car air conditioners have become an essential part of cars, and evaporators are important components of car air conditioners. Improvements are being made, but the current evaporator refrigerant flow rate is too small, the utilization rate of refrigerant is not high, and the heat exchange efficiency still cannot meet the requirements.
