The temperature sensor is hoisted in the liquid cooling box 1 through a rope, when the temperature detected by the temperature sensor is too high, the control system controls the electric telescopic rods above the partition boards 12 positioned at two sides of the section to work, the racks are driven to move through the electric telescopic rods, the through holes of the first water chestnut board 14 and the second water chestnut board 15 positioned at different rows on one partition board 12 face the same direction under the driving of the upper gear 10 and the lower gear 9, the through holes of the first water chestnut board 14 and the second water chestnut board 15 positioned on the two partition boards 12 face opposite directions, the through grooves of the first water chestnut board 14 and the second water chestnut board 15 are closed, so that the cooling liquid in the high temperature section is prevented from flowing into the low temperature section, and the temperature transmission is further blocked; through the position adjustment of the first diamond plate 14 and the second diamond plate 15, the driving pipe 11 can extract the cooling liquid in the high-temperature interval, so that the replacement of the cooling liquid in the high-temperature interval is accelerated, and the temperature of the server in the interval is rapidly reduced. When the temperature in the high temperature interval is reduced or the cooling liquid in the high temperature interval is pumped for a period of time, the first diamond plate 14 or the second diamond plate 15 is reset under the drive of the driving pipe 11, and after waiting for a period of time, if the temperature in the high temperature interval is still higher than the set cooling temperature, the through holes on the first diamond plate 14 and the second diamond plate 15 face the same direction again.
After the upper end cover of the liquid cooling box 1 is installed, the inside of the liquid cooling box 1 is in a sealed state, the air pressure is normal pressure, and as the server is installed in the liquid cooling box 1, the temperature in the liquid cooling box 1 is higher than the temperature in the second-stage box 24, so that the air pressure in the liquid cooling box 1 is higher than the air pressure in the second-stage box 24, a refrigerating sheet is installed in the second-stage box 24, after the refrigerating sheet works, the temperature in the second-stage box 24 is reduced, so that the air pressure in the second-stage box 24 is further reduced, and the air pressure difference between the liquid cooling box 1 and the second-stage box 24 is increased; the centrifugal fan 26 is driven by the rotating motor to rotate, the centrifugal fan 26 is connected with the converging tube 27 through a rotary sealing ring, when the centrifugal fan rotates rapidly, the air flow velocity outside the fan blades is high, so that the air inside the fan blades flows outwards, the centrifugal fan 26 generates low pressure, the cooling liquid in the liquid cooling box 1 flows through the driving tube 11, the branch tube 5, the main tube 6, the transmission tube 3, the liquid inlet tube 22, the radiating tube 29 and the converging tube 27 under the action of air pressure difference, finally flows into the centrifugal fan 26, and continuously sprays the cooling liquid into the secondary box 24 under the action of centrifugation, the cooling liquid continuously flows into the centrifugal fan 26 under the action of the pressure difference, and the cooled cooling liquid is pumped back to the liquid cooling box 1. When the reflux pump needs to be replaced, the valve is temporarily closed, the rotating motor drives the centrifugal fan 26 to rotate, the low pressure generated by the centrifugal fan 26 and the low pressure generated by the refrigerating sheet in the secondary tank 24 can temporarily play a role of a pump, the cooling liquid is pumped from the liquid cooling tank 1 to the secondary tank 24, the non-stop operation during the replacement of the reflux pump is achieved, after the replacement of the reflux pump is completed, the valve is opened, and the reflux pump is still used as a power source for driving the cooling liquid to circularly flow.
When the rotating motor needs to be replaced, the rotating motor is directly disassembled, and the reflux pump pumps the cooling liquid or air in the secondary tank 24, so that the air pressure in the secondary tank 24 is lower than the air pressure in the liquid cooling tank 1, and the cooling liquid in the liquid cooling tank 1 still flows into the branch pipe 5, the main pipe 6, the transmission pipe 3, the radiating pipe 29 and the secondary tank 24 under the action of air pressure difference, so that the rotating motor is replaced without stopping operation.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
