Abstract

The invention discloses a method for designing the structure of a tree-shaped heat pipe through particle swarm evolution and application. According to the method, the evaporation section of the tree-shaped heat pipe is designed through the steps of geometric modeling of the tree-shaped heat pipe, establishment of the target function for designing the tree-shaped heat pipe according to the requirements of thermal design, calculation of the target function through the particle swarm evolutionary algorithm and the like, and the tree-shaped heat pipe structure with the good heat transfer characteristic can be obtained. According to the structure, the heat dissipation capacity of the whole heat pipe in some areas with large heat flow density can be improved by increasing the distribution density of the micro-channels in the areas, and wide research prospects are achieved.

Description

technical field [0001] The invention belongs to the field of heat dissipation equipment or heat exchange equipment, and in particular relates to a method and application for designing the structure of a tree-shaped heat pipe by particle swarm evolution. Background technique [0002] In recent years, the application of electronic products and electronic equipment has become more and more extensive, and some electronic components and integrated circuits are usually used in the manufacture of them.
