Description

Heat exchanger structure optimization method based on hot melt gas-liquid two-phase heat exchange structure technical field The present invention relates to the field of heat exchanger structure, especially relate to a kind of based on hot melt type gas-liquid two-phase heat exchange structure. Heat exchanger structure optimization method. Background technique The traditional heat exchanger structural design relies on the manufacturing process of subtractive manufacturing, and it is difficult to make relatively complex shapes, one To a certain extent, the further improvement of the relevant heat exchange efficiency is limited. Although the related design relies on reducing the cell spacing and increasing the ripple The plate method effectively increases the relevant contact area, but still cannot get rid of the fact that the heat transfer area is smaller than the material area. none The method achieves the full utilization of the material area, resulting in a certa...
