The invention relates to a heat exchanger structure optimization method based on a hot-melt type gas-liquid two-phase heat exchange structure, which includes the following steps: S1: according to the hot-melt type gas-liquid two-phase heat exchange structure and based on sine and cosine functions, construct a heat exchanger Melt-type gas-liquid two-phase heat transfer function; S2: Carry out three-dimensional modeling to construct the heat transfer unit. S3: Repeat step S2, adjust parameters, and obtain the optimal unit body that meets the preset gas-liquid volume ratio condition; S4: Obtain the aggregate unit composed of the optimal unit body through rapid iterative array; S5: Repeat step S4, Obtain the optimized set with the best surface area and quality; S6: Perform stress optimization; S7: Perform 3D printing optimization; S8: Integrate the optimized set to obtain the final heat exchanger structure. Compared with the prior art, the present invention adopts a hot-melt type gas-liquid two-phase heat exchange structure, which breaks through the selection of traditional design structure modes, and achieves double breakthroughs in heat transfer efficiency and weight.
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...
