[0024] In addition, one end of the discharge pipe 424 located at the bottom of the upper cover 42 is inserted and connected to the suction pipe 10, and the suction pipe 10 is arranged in the cavity of the container 41. The other end of the exhaust pipe 421 away from the upper cover 42 is connected to the gas container 5. The exhaust pipe 421 cooperates with the exhaust valve 8 on the mounting plate 3 to effectively discharge the helium released from the reaction in the thermal conductive gel into the gas container 5 through the exhaust pipe 421.

[0025] In addition, scale lines 411 are provided on the side wall of the container 41 , and the scale lines 411 are convenient for operators to observe the amount of the thermal conductive gel in the container 41 .
