Benefits of technology

This patent is about a new structure for a water-cooling radiator that prevents the air pressure inside the radiator from getting too high, which can cause leakage. The structure is called a piston-based pressure reduction system, and it is connected to the cooling liquid in the radiator. When the pressure inside the radiator is too high, the piston moves to release the pressure, so that the air pressure does not get too high. This prevents liquid leakage and ensures the radiator operates safely and efficiently.

Problems solved by technology

However, after the radiators operate in a high-temperature environment for a period of time, a high pressure will be generated in the radiators; and once the high pressure in the radiators reaches a certain value, poor-sealing parts of the radiators will be cracked, which in turn results in liquid leakage of the radiators.
1. Although the maturity of the manufacturing process has decreased the leakage rate, the leakage risk has yet to be eradicated, and computer hardware will be burned once a liquid leakage occurs.
2. If the interior of the radiators is in a high-pressure state for a long time, the components such as seal rings will be in a fatigue state all the time, and the leakage probability becomes larger gradually over time.
3. Pure sealing reinforcement will make the radiators more complex and increase costs and also limits design and manufacturing in many aspects.

embodiment 1

[0040]As shown in FIG. 1, a piston-based pressure reduction structure used for a water-cooling radiator comprises a shell 11 and a piston structure 2, wherein the piston structure 2 is movably arranged in the shell 11. A pressure release hole 12 is formed in one end of the shell 11, and an inner cavity of the shell 11 is communicated with cooling liquid in the water-cooling radiator via the pressure release hole 12. A vent hole 13 communicated with the external atmosphere is formed in the other end of the shell 11. The side wall of the piston structure 2 is tightly attached to the inner wall of the shell 11 and is slidably connected with the inner wall of the shell 11. The piston structure 2 is used for isolating the vent hole 13 from the pressure release hole 12.

[0041]In this solution, the position of the piston structure 2 in a normal state is shown in FIG. 4; as the internal pressure, such as an air pressure or a hydraulic pressure, can be applied to one end face of the piston st...

embodiment 2

[0044]As shown in FIGS. 4, 5, and 6, a water-cooling radiator comprises a water cooler 3, a water block 4, and a water pump, wherein the water cooler 3 is communicated with the water block 4. According to the water-cooling radiator, cooling liquid absorbs heat via the water block 4, and the cooling liquid is delivered by the water pump into the water cooler 3; and the cooling liquid in the water-cooling radiator flows through the water cooler 3 to be cooled. The water-cooling radiator further comprises a piston-based pressure reduction structure 1 which comprises a shell 11 and a piston structure 2, wherein the piston structure 2 is movably arranged in the shell 11; a pressure release hole 12 is formed in one end of the shell 11, and an inner cavity of the shell 11 is communicated with the cooling liquid in the water-cooling radiator via the pressure release hole 12; a vent hole 13 communicated with the external atmosphere is formed in the other end of the shell 11; the side wall of...

embodiment 3

[0047]As shown in FIG. 7, this embodiment differs from embodiment 2 in the following aspects: the shell 11 is connected into the water block 4 or is integrally formed in the water block 4, and the cooling liquid in the water block 4 flows through the inner cavity of the shell 11 via the pressure release hole 12; and in addition, the piston limiting part 14 is a cover plate structure and is provided with a plurality of through holes 11 allowing screws to penetrate through, the shell 11 is provided with corresponding screw holes, and the piston limiting part 14 is installed on the shell 11 with screws. Compared with embodiment 2, the shell 11 is arranged at a different position in this embodiment, while the pressure release way and the pressure release effect of this embodiment are the same as those of embodiment 2 and will not be detailed anymore herein.
