Description

technical field

[0001] The invention relates to the field of heat exchanger structures, in particular to a heat exchanger structure optimization method based on a hot-melt type gas-liquid two-phase heat exchange structure. Background technique

[0002] The traditional heat exchanger structure design relies on the manufacturing process of subtractive manufacturing, and it is difficult to manufacture more complex shapes, which limits the further improvement of related heat exchange efficiency to a certain extent. Although the relevant design relies on reducing the unit spacing and increasing the corrugated plate to effectively increase the relevant contact area, it still cannot get rid of the fact that the heat transfer area is smaller than the material area. It is impossible to make full use of the material area, resulting in a certain waste.

[0003] At the same time, in today's standardization and maturity of the plates, the constraints of the process have also led to the ...
