[0032] Working principle: This utility model is provided with a head 13 and a shell 11. A first flange 16 is symmetrically welded to both ends of the shell 11. A second flange 15 is welded and fixed to one end of the head 13. The first flange 16 and the second flange 15 are fixed by connecting bolts 12. A sealing groove 25 is formed on the side wall of the first flange 16, and a sealing ring 26 is embedded in the sealing groove 25 to ensure the connection and sealing of the first flange 16 and the second flange 15. Fixing discs 8 are symmetrically welded to both ends of the inner cavity of the shell 11, and several tubes 10 are uniformly welded and fixed between the two fixing discs 8. A liquid carbon dioxide inlet pipe 7 is welded and connected to one side wall of the head 13, and a gaseous carbon dioxide outlet pipe 14 is welded and connected to the other side wall of the head 13. A refrigerant inlet pipe 20 is welded to one side of the inner cavity of the shell 11, and a refrigerant outlet pipe 21 is welded to the other side of the inner cavity of the shell 11. When liquid carbon dioxide is introduced into the inner cavity of the end cap 13 through the liquid carbon dioxide inlet pipe 7, the liquid carbon dioxide can evenly enter each tube 10. At this time, the refrigerant is introduced through the refrigerant inlet pipe 20 and rapidly exchanges heat with the liquid carbon dioxide through the tube 10, causing the liquid carbon dioxide to evaporate rapidly and absorb heat, thus rapidly cooling the refrigerant. The refrigerant with cooling capacity is then discharged through the refrigerant outlet pipe 21 for use, while the evaporated gaseous carbon dioxide is discharged through the gaseous carbon dioxide outlet pipe 14. After being pressurized and condensed by the compressor, it can be recycled. The shell 11 and The outer wall of the end cap 13 is bonded with a heat insulation layer 9 to reduce the loss of cold energy and improve the efficiency of cold energy utilization, making it more practical. This utility model includes a mounting base 1, an end cap 13, and a shell 11. Mounting blocks 18 are symmetrically welded to both sides of the mounting base 1, and mounting bolts 19 are screwed onto the mounting blocks 18. The mounting base 1 can be fixedly installed using the mounting blocks 18 and mounting bolts 19. The mounting base 1 has an inner cavity 2, and a clearance slot 22 penetrating the mounting base 1 is opened at the top of the mounting cavity 2. A connecting block 4 is slidably fitted into the clearance slot 22. The shell 11 is fixedly welded to the top of the connecting block 4, and an adjusting plate 3 is welded to the bottom of the connecting block 4.

A guide slide sleeve 5 is welded and fixed to the other side of the adjusting plate 3, and the guide slide rod 6 is sleeved inside the guide slide sleeve 5. Therefore, when the user rotates the adjusting screw 23 by adjusting the knob 17, the adjusting plate 3, along with the connecting block 4, can be moved up and down along the direction of the guide slide rod 6, thereby pushing the housing 11 to move up and down. This facilitates the adjustment of the docking height of the liquid carbon dioxide inlet pipe 7, the gaseous carbon dioxide outlet pipe 14, the refrigerant inlet pipe 20, and the refrigerant outlet pipe 21, thus broadening the installation applicability.More practical.
