Abstract

The previous research on ultra-high power laser was mostly focused on discharge tubes and resonator. However, little attention was focused on the heat exchange performance, which is also an essential technology to ensure the long time stable work of the CO₂ laser. The purpose of this paper is to characterize the heat exchange performance of CO₂ laser and to supply the method of heat exchanger design. Considering the inner heat cycle and characteristics of the 10 KW fast axial flow CO₂ laser which is under development, various types of heat exchangers were compared, rectangle finned heat exchanger was chosen as the laser radiator, in light of the prominent heat transfer capacity and compact structure. Further more, this paper also established the heat balance equation, calculated the heat transfer capacity. The results indicate that the rectangle finned circle tube heat exchanger which has been chosen is suitable to 10 KW fast axial flow CO₂ laser.
