Abstract: In view of the internal heat dissipation problem caused by the power loss of high-power microwave power supply, a heat dissipation scheme combining forced water cooling and forced air cooling is designed. Firstly, through the analysis of the structure, flow field and thermal field inside the case, the heat dissipation design of high-power microwave power supply is carried out; Then, the three-dimensional model of high-power microwave power supply box is established and simplified; Finally, the fluid-structure coupling heat transfer simulation analysis is carried out using ANSYS simulation software to optimize the structure design of high-power microwave power supply, meet its heat dissipation requirements, and solve the heat dissipation problem of heating devices.
