冷却器面积增加冷却器效能相对增加，冷却器换热量相对减少；氦氙体积比增加冷却器效能先下降后上升，冷却器换热量逐渐上升。

With the increase of cooler area, the efficiency of cooler is relatively increased, and the heat transfer of cooler is relatively reduced. As the volume ratio of helium to xenon increases, the efficiency of the cooler decreases first and then increases, and the heat exchange capacity of the cooler gradually increases.
