  • In order to solve the problem of heat conduction of a solar simulation xenon lamp array used in a vacuum tank, a special heat conduction mechanism for xenon lamps is designed by using a heat pipe technology. The heat conduction ability of the cooling system is calculated, and the results indicate that the temperature change ΔT of liquid nitrogen cooling system is 2.074 1 K, lower than a super cooling temperature of 4 K, which points out that the liquid nitrogen cooling system can export the heat of solar simulation xenon lamp array out from the vacuum tank. A heat conduction mechanism is designed, and the finite element analysis is used to carry out thermal simulation analysis. The thermal simulation analysis results show that the temperatures for the anode and cathode of xenon lamp and the bulb of xenon lamp are about 100 ℃ and 655 ℃, respectively. Moreover, the temperatures of an optical integrator and mirror are both about 200 ℃ and the temperature of an ellipsoidal mirror is about 135 ℃, which meets the normal working conditions for a long period. The results obtained prove that the thermal design is feasible and reasonable.
