The refrigerant in the refrigeration system is directly output and evaporated into the target control element (heat exchanger) for heat exchange, thereby cooling the target control object. The heat exchange capacity is generally more than 5 times higher than that of the fluid (gas) transported into the heat exchanger, which is especially suitable for applications where the heat exchange area of the heat exchanger is small but the heat exchange is large. It can also be used such as gas capture, the refrigerant is directly passed into the trap to evaporate, and through the condensation effect on the surface of the trap, it is quickly inferior to the gas in the air.

There is a certain residual gas in the high vacuum environment where the oil diffusion pump is used, more than 80% of which are water vapor, oil vapor and other high boiling point steam, but the ability to remove residual gas is low, the time is long, and all residual gas is The gas is also a source of contamination of the workpiece, which affects the yield and quality of the product. The ultra-low temperature direct cooler is the best choice to solve this kind of problem.

The working principle of the direct-cooling ultra-low temperature refrigerator: a refrigeration coil that can reach below -120°C is placed in the vacuum chamber or the pump port of the oil diffusion pump, and the vacuum system is quickly captured by the low-temperature condensation effect on its surface. of residual gas. Thus, the vacuuming time is greatly shortened (60-90% of the vacuuming time can be shortened), and a clean vacuum environment is obtained.
