| Abstract: | Laser communication terminal is a new signal transmission carrier. The equipment-s optics-device parts bring high heat dissipation, and require higher equality and stability of the temperature. It is a challenge for thermal control. According to the characteristic of the laser communication terminals and the rule of outer space heat flux, a new way for thermal control was designed as the following: heat-conducted plate and heat pipe were adopted for heat transfer of high heat-flux parts, and high precision temperature control methods were applied for key parts. A numerical simulation was investigated in uttermost cases by thermal desktop analysis software, and the results prove the design correct. |
