针对研制的千瓦级快速轴流高功率CO2激光器的内部循环热交换工作过程,建立了热量的平衡方程;针对激光器工作的特点,比较分析了几类热交换器的

Inner heat cycle of designed kW fast axial flow CO 2 laser is discussed, and the heat balance equation is eastablished. Technical key of heat exchanger for this kind of laser is given, and compared with several other kinds of heat exchangers. Rectangle fin circle tube heat exchanger is chosen as the laser′s radiator, and its conducting heat is calculated. The result indicates that the rectangle fin circle tube heat exchanger which has been chosen is suitable to our kW fast axial flow laser.
