The following embodiments are used to illustrate the utility model.
[0028] A distributed cooling component, such as Figure 1 , Figure 2 As shown, it includes a fixed part for controlling the position of the immune cell container and a sealing plate adjustment plate for achieving the sealing purpose, the fixed part includes a freezing box 10, the cavity of the freezing box 10 is hollow, the sealing plate adjustment plate includes a connecting plate 15, the cavity of the connecting plate 15 is hollow, a sealing plate 16 is fixedly installed on the bottom wall of the connecting plate 15, and a clamping device for sealing the freezing box 10 is arranged in the cavity of the connecting plate 15, the clamping device includes a limiting rod 21 for connecting the connecting plate 15 with the freezing box 10 and a moving block 19 for controlling the movement of the limiting rod 21.
[0029] During the specific working process, the main material of the freezing box 10 is stainless steel. Stainless steel has strong toughness and can effectively protect the immune cells in the cavity. The cavity of the connecting plate 15 is hollow, so the corresponding connecting plate 15 is light in weight, which allows the staff to easily pick up the connecting plate 15. The locking device arranged in the cavity of the connecting plate 15 enables the connecting plate 15 to be locked with the freezing box 10, and the purpose of sealing the freezing box 10 is achieved through the bottom arrangement of the connecting plate 15.
[0030] like Figure 2 As shown, a sealing groove 13 is provided on the top wall of the freezing box 10, and the sealing groove 13 is T-shaped. Connecting grooves 14 are provided on the inner walls on both sides of the sealing groove 13. There are two connecting grooves 14 in total, and the two connecting grooves 14 are in parallel. The position of the sealing groove 13 corresponds to the position of the connecting plate 15.
[0031] During the specific working process, the sealing groove 13 opened on the top of the freezing box 10 corresponds to the position of the connecting plate 15, and the connecting groove 14 opened on the inner wall of the sealing groove 13 is used to connect with the locking device, thereby achieving the purpose of connecting the sealing groove 13 and the connecting plate 15.
[0032] like Figure 2-Figure 4 As shown, there are two limit rods 21, and the two limit rods 21 are movably installed in the cavity of the connecting plate 15. The position of the limit rod 21 corresponds to the position of the connecting groove 14. The limit rod 21 is movably installed in the corresponding connecting groove 14 cavity. The limit rods 21 all penetrate the connecting plate 15, and a movable rod 20 is fixedly installed on the top wall of one end of the limit rod 21 extending into the cavity of the connecting plate 15. A movable groove 18 is provided on the top wall of the connecting plate 15, and the position of the movable groove 18 corresponds to the position of the movable rod 20. The movable rod 20 is movably installed in the movable groove 18 cavity. The movable rod 20 all penetrates the corresponding movable groove 18, and a moving block 19 is fixedly installed on the top wall of the movable rod 20. The moving blocks 19 are movably installed on the top wall of the connecting plate 15. A spring 22 is fixedly installed on the outer wall of one end of the limit rod 21 extending into the cavity of the connecting plate 15, and the other end of the spring 22 is fixedly connected to the inner wall of the connecting plate 15.

When the limit rod 21 moves into the cavity of the connecting groove 14, the purpose of connecting the connecting plate 15 and the freezing box 10 is achieved.
[0034] like Figure 4 As shown, a volatilization tube 17 is fixedly installed on the top wall of the connecting plate 15 for volatilizing and discharging the nitrogen liquid in the cavity of the freezing box 10. The volatilization tube 17 is L-shaped, and the volatilization tube 17 passes through the corresponding connecting plate 15 and the sealing plate 16 and extends into the corresponding cavity of the freezing box 10.
[0035] During the specific working process, the volatilization tube 17 passes through the connecting plate 15 and the sealing plate 16. When the connecting plate 15 is connected to the cavity of the sealing groove 13, the volatilization tube 17 extends into the cavity of the freezing box 10. The nitrogen liquid in the cavity of the freezing box 10 evaporates outward through the volatilization tube 17, thereby stabilizing the air pressure in the cavity of the freezing box 10 to prevent the air pressure from being too high or too low, causing the freezing box 10 to deform and affecting the freezing of the immune cells in the cavity of the freezing box 10.

[0037] In the specific working process, the nitrogen liquid pipe 11 runs through the freezing box 10. When the nitrogen liquid needs to be supplemented in the cavity of the freezing box 10, the nitrogen liquid tank is connected to the valve 12, and the valve 12 is opened to transport the nitrogen liquid to the cavity of the freezing box 10 through the nitrogen liquid pipe 11, thereby ensuring that the nitrogen liquid in the cavity of the freezing box 10 is sufficient. By setting the limiting holes 24, there are several limiting holes 24, and the limiting holes 24 limit the position of the corresponding tube body 25, so as to control the tube body 25 to be vertical in the cavity of the freezing box 10.

A tube cap 26 is movably installed on the top wall of the tube body 25. The tube body 25 and the tube cap 26 are threadedly connected. Scales 27 are arranged on the outer wall of the tube body 25. The scales 27 are evenly distributed on the outer wall of the corresponding tube body 25. Ceramic beads 28 are arranged in the cavity of the tube body 25. There are several ceramic beads 28, and adsorption holes are opened on the outer wall of the ceramic beads 28.
[0039] In the specific working process, the tube body 25 is sealed by the tube cap 26, and the position of the solution set in the cavity of the tube body 25 is observed through the scale 27, and the ceramic beads 28 are provided with adsorption holes to facilitate the adsorption of immune cells.
