Problems solved by technology

[0002] At present, most of the subcooled parallel flow condensers used in automotive air-conditioning systems use four-flow common flow channels, but this kind of common flow channels does not make full use of the heat exchange capacity of the condenser.

Embodiment Construction

[0016] figure 1 and figure 2 It is a schematic structural diagram of the flow channel of a novel parallel flow condenser for automobiles of the present invention, including a header 1, an inlet 6 for the inflow of the refrigerant is arranged near the middle of the header 1, and the upper and lower ends of the header 1 are respectively provided with a refrigerant supply. Outgoing upper outlet 2 and lower outlet 3.

[0017] It also includes a transition pipe 4, and both the upper outlet 2 and the lower outlet 3 communicate with the transition pipe 4; Half of the flat tubes at the inlet 6 extend to the upper outlet 2 and the lower outlet 3 respectively. The flat tube extends in an "S" shape.

[0018] In order to further verify the heat exchange effect, rapid prototyping parts were made according to the above flow channels and the prior art flow channels, respectively, and the following data were obtained as a reference after performance testing:

Abstract

The invention discloses a novel automobile parallel flow condenser channel. The novel automobile parallel flow condenser channel comprises a pick- up tube (1), an entrance (6) used for the inflowing of refrigerant is arranged around the middle part of the pick- up tube (1), the upper end of the pick- up tube (1) and the lower end of the pick- up tube (1) are connected with a upper exit (2) and a lower exit (3) respectively, and the upper exit (2) and the lower exit (3) are used for the inflowing of refrigerant. The gas with high temperature and high pressure can participate in the heat transfer sufficiently in a top and bottom bipartition mode after entering the condenser, heat exchanger efficiency of the condenser is improved greatly, and the heat exchange capability is improved greatly without adding fins and flat pipe.

Description

technical field [0001] The invention relates to the technical field of novel automobile air conditioners, in particular to a novel automobile parallel flow condenser flow channel. Background technique [0002] At present, most of the subcooled parallel-flow condensers used in automotive air conditioning systems use four-pass common flow channels, which do not fully utilize the heat exchange capacity of the condenser. [0003] The heat exchange capacity of the parallel flow condenser mainly depends on the fins, flat tubes and headers. With the development of science and technology, the space in the front cabin of the whole vehicle is becoming more and more compact, and the assembly space left for the condenser is not large. Therefore, How to improve the heat exchange efficiency of the condenser is imminent, and it is also a development direction of the heat exchanger in the future. [0004] The general design principle of the flow passage of the condenser is: with the flow o...
