Abstract

In this paper, the finite element analysis method is used to simulate the heat dissipation effect of the water-cooling channel in a conical mirror when high power laser (10⁴ W level) is irradiated on it. Several important factors affecting the heat dissipate, such as the inlet flow velocity, loaded laser power and the mirror material, are analyzed systematically. The temperature distribution of the conical mirror with the parameters’ variation is obtained, and the relationship between the above parameters and the temperature results are discussed. Finally, based on the thermal analysis of the water-cooling channel structure of the conical mirror under high power laser, we can find that the water-cooling channel structure can greatly improve the cooling capacity and effectively achieve heat dissipation of the conical mirror.
