Specifically, a sealing rubber ring is arranged at the joint of the output conduit 4 and the output port 3 or the joint is connected in a dispensing manner, so that liquid is prevented from overflowing from the joint of the output port 3 and the output conduit 4.
The float 5 is accommodated in the accommodating space 11 and floats on the liquid, and is used for monitoring the pressure degree of the gas in the container 1 and guiding part of the gas out to relieve the pressure in the container 1 when the gas pressure is higher. Specifically, when the external device equipped with the liquid-cooled circulating heat dissipation system 100 has high working power, the generated heat is correspondingly increased, at this time, the heat absorbed by the liquid-cooled circulating heat dissipation system 100 is large, and the temperature of the liquid flowing into the container 1 is high, so that the temperature of the gas in the container 1 is increased, the pressure is increased, the gas can be led out through the buoy 5, and the phenomenon that the liquid exchange of the whole liquid-cooled circulating heat dissipation system 100 is affected due to too large gas pressure is avoided.

The automatic pressure relief function is realized, and the air pressure in the accommodating space 11 is ensured not to influence the input and output of the liquid due to overhigh pressure.
Specifically, in the present embodiment, when the gas pressure in the housing space 11 is too high, the gas pressure presses the float 5, and the gas is sent to the hose 7 through the opening 511 of the float 5 and then to the pressure reducing device 6, and when the gas pressure is greater than the opening threshold of the pressure reducing device, the gas enters the float 5 and is discharged through the pressure reducing device 6.
Of course, the liquid-cooled circulation heat dissipation system 100 may further include the input conduit 8, and the input conduit 8 is inserted into the input port 2 to connect the liquid-cooled circulation pipe 20, so as to introduce the liquid in the liquid-cooled circulation pipe 20 into the container 1. Specifically, a sealing rubber ring is arranged at the joint of the input conduit 8 and the input port 2 or the joint is connected in a dispensing manner, so that liquid is prevented from overflowing from the joint of the output port 3 and the output conduit 4.
The arrangement of the above structure makes the liquid cooling circulation heat dissipation system 100 or the container 1 set at any angle, the liquid inlet 41 of the output conduit 4 is always located below the liquid level of the liquid, and a pump valve device can be arranged outside the liquid cooling circulation system 100 to pump the liquid in the container 1 and enter the liquid cooling circulation pipeline 20 for heat dissipation circulation.
