Problems solved by technology

At present, the mainstream parallel-flow evaporator adopts a rectangular structure, including a plurality of straight flat tubes arranged side by side. The straight flat tubes are separated by pleated fins, and the refrigerant inlet and outlet ends of the straight flat tubes are connected to the header. , the shortcomings are: the rectangular structure occupies a large area, especially the stacked parallel flow with multiple straight flat tubes stacked, which increases the thickness, which is extremely unfavorable for the layout of small cars; moreover, the parallel flow evaporates The straight flat tube used in the device is easy to expand or vibrate and deform under certain harsh conditions, which affects the circulation of the refrigerant; again, for the straight flat tube, the refrigerant stroke is short and the cooling efficiency is not high enough, and in some working environments Vehicles have a large demand for refrigeration and have higher requirements for refrigeration efficiency; in addition, the production process of pleated fins is complicated, and brazing is difficult, and flat tubes, headers, and fins are mostly assembled manually, which is difficult to assemble

Embodiment Construction

[0018] refer to Figure 1-5 A vortex parallel-flow counter-current evaporator for automobile air-conditioning, comprising a cylindrical shell 1, the cylindrical shell 1 is provided with a plurality of vortex-shaped flat tubes 8 arranged in parallel, and each vortex-shaped flat tube The tubes 8 are separated by fins 9, and the inner side of the cylindrical housing 1 is provided with slots connected with the fins 9; Adjacent vortex layers are sealed and connected to the fins 9 on both sides to form a refrigerant channel for heat exchange with the refrigerant. The inlet and outlet of each refrigerant channel are connected to each other, and the inlet and outlet of each refrigerant channel The outlets are respectively connected to each other, and the refrigerant in the refrigerant passage and the brine in the brine passage flow in reverse directions. The outermost end of the scroll-type flat tube 8 is arranged with a first header 4 communicating with the outlet of each refrigeran...

Abstract

The invention relates to a vortex parallel flow countercurrent evaporator for an automotive air conditioner, which comprises a plurality of vortex type flat tubes, wherein the vortex type flat tubes are arranged in parallel, extended to form a vortex shape and separated by fins; refrigerant runners are formed in cavities of the vortex type flat tubes; the adjacent vortex layers of individual vortex type flat tubes are in sealing connection by the fins on two sides to form secondary refrigerant runners exchanging heat with refrigerants; inlets and outlets of each refrigerant runner are communicated with one another respectively; the inlets and outlets of each secondary refrigerant runner are communicated with one another respectively; and the refrigerants in the refrigerant runners and secondary refrigerants in the secondary refrigerant runners flow reversely. The vortex parallel flow countercurrent evaporator for the automotive air conditioner has a simple structure, occupies a small area, is difficult to deform by stress, vibration, thermal expansion and the like under severe conditions to influence the sections of the runners, makes smooth the circulation of the refrigerant, remarkably increases the travel of the refrigerant, improves the refrigeration efficiency and greatly reduces machining difficulties.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to a parallel-flow vortex counter-flow evaporator. Background technique [0002] The car air-conditioning evaporator is one of the core components of the car air-conditioning system. The design of the evaporator directly affects the performance of the air-conditioning system and affects the compactness of the vehicle. At present, there are many types of evaporators used in automotive air conditioners, mainly including tube-sheet type, tube-belt type, stacked type, parallel flow type, etc. Early automotive air-conditioning evaporators were generally of tube-sheet structure, and then developed into tube-belt structure until the current mainstream parallel-flow or even stacked parallel-flow evaporators. [0003] With the development of automobile industry and automobile air-conditioning industry, automobile air-conditioning evaporators are developing in the direction of high...
