AI Technical Summary

Problems solved by technology

Multiple creases generate a lot of folding stress, and if the folding stress cannot be released well, it will easily lead to loosening of the overlapping parts, such as figure 1 shown
This is detrimental to the assembly and welding quality of the heat exchanger, which is not conducive to improving the heat transfer efficiency of the heat exchanger

Embodiment Construction

[0033] The parallel flow heat exchanger using the multi-channel folded flat tube according to the present invention can be applied to, but not limited to, the field of refrigeration and air conditioning, the field of electronic cooling, the field of power equipment cooling, or the field of generator cooling.

[0034] The multi-channel folded flat tube according to the invention is generally made of multi-layer composite aluminum material, preferably formed by a rolling process. The multi-layer composite aluminum material is flexible in design. Compared with extruded flat tubes, it has better mechanical properties and anti-corrosion capabilities, and also has the potential to reduce the weight of products.

[0035] The preferred embodiment of the multi-channel folded flat tube for heat dissipation of parallel flow heat exchanger according to the present invention will be referred to below Figure 2-4 to describe.

Abstract

The invention provides a multi-channel folded flat tube, which includes a first member and a second member which are formed separately and assembled together, the first and second members respectively have a flat section and a flat section connected with the flat section and attached to the flat section meandering section, the meandering sections of the first and second members are arranged laterally side by side and form a plurality of channels extending longitudinally between the flat sections of the first and second members, the flat sections of the first and second members Defining two opposing main walls constituting said multi-channel folded flat tube, wherein the first and second members include snap-fit ​​structures formed of their own material, by which the first and second members are secured to the Together to form the multi-channel folded flat tube.

Description

technical field [0001] The invention relates to a multi-channel folded flat tube for heat dissipation, especially a multi-channel folded flat tube used in the field of parallel flow heat exchangers. Background technique [0002] Parallel flow heat exchangers are more and more widely used in related fields such as automotive air conditioners, household air conditioners and even heat pump units because of their advantages such as small air side resistance, high heat transfer efficiency, wide application range, and easy recycling. They can also be used to cool electronic equipment or generator equipment, etc. [0003] The aluminum alloy extruded microchannel flat tube is the main component of the parallel flow heat exchanger. However, the precision extrusion of aluminum alloy is difficult and costly, and the material options are limited. In practical applications, corrosion is its main failure mode. [0004] US patent US 7657986B2 discloses a method of manufacturing condense...
