Embodiment Construction
[0086] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. The design method proposed by the present invention can optimize the design of the liquid flow channel layout for various heat dissipation structures. The heat dissipation area is uniformly generated in the following, and a point on the boundary of the area is a heat sink. Taking the problem as an example, the present invention will be described.
[0087] refer to figure 1 , a topology optimization design method for a cold plate liquid flow channel of a power electronics integrated module, comprising the following steps:
[0088] 1) Initialization of the adaptive growth of the cold plate liquid flow channel:
[0089] 1.1) Construction of the growth area: the base structure (radiation area) and its thermal load boundary conditions are as follows figure 2 As shown; the size of the area is 40mmX40mm; the heat is uniformly generated in the area, and the ...
