The invention provides a sealing mechanism and a two-phase water-cooling heat dissipation device thereof, particularly a sealing mechanism and a two-phase water-cooling heat dissipation device that can apply pressure evenly and effectively avoid structural deformation.

The traditional immersed water-cooling equipment places the objects to be cooled in the storage space of the tank, and then installs the cover plate on the tank to cover the storage space, and uses the water-cooling device in the water-cooling equipment for cooling; however, the water-cooling device The cooling liquid will vaporize due to heating, so the cover of the water-cooling equipment needs to provide stable pressure and adhesion to the tank to prevent gas from escaping. The cover has first and second opposite sides. The first side is close to the pivot mechanism, and the pivot mechanism is used to rotatably set the cover plate in the tank; the second side is far away from the pivot mechanism, and the user can apply force on the second side or on the cover plate. section other than the first side to open or close the cover. When the cover is closed in the tank, it will first press the section of the annular washer close to the pivot mechanism; only when the second side of the cover is closed, will it press the other section of the annular washer away from the pivot mechanism. section. Uneven stress on the ring gasket will cause inconsistent compression. Furthermore, a linkage mechanism is provided on the cover plate to fix the cover plate to the tank body to prevent gas from escaping. However, the linkage mechanism is prone to structural deformation due to excessive pressure difference between the inside and outside of the tank body. Therefore, when closing the cover of traditional immersed water-cooling equipment, shortcomings such as the ring gasket falling out of the installation groove of the tank body, the cover plate bending and deforming due to force, or the linkage mechanism structural deformation may occur, thus affecting the performance of the immersed water-cooling equipment. Air tight effect.

The restraining member 16 can be disposed around the periphery of the groove body 14 . Other structural components are not the focus of the design of the present invention, so they will not be described in detail.

The heat emitted by the heating element 20 is absorbed by the heat dissipation medium 18 , causing the heat dissipation medium 18 to convert from the liquid phase to the gas phase. After the gas phase heat dissipation medium 18 discharges the heat, it is converted into the liquid phase heat dissipation medium 18 through condensation.

The sealing mechanism 24 can be engaged with the restraining member 16 to press the cover plate 22 to ensure that the cover plate 22 can tightly seal the opening of the tank body 14, effectively preventing leakage of the liquid or gas phase heat dissipation medium 18.

It is worth mentioning that the casing 12 can selectively provide grooves (not marked in the drawings) around the groove body 14, and an elastic member slightly larger than the groove is placed in the groove (not marked in the drawings). . The sealing mechanism 24 drives the cover plate 22 to vertically press the elastic member, allowing the elastic member to deform under pressure and fill the groove tightly, ensuring that when a pressure difference occurs between the inside and outside of the casing 12, the elastic member will not be affected by the gas phase heat dissipation medium 18 The impact and excessive deformation cause the heat dissipation medium 18 to leak out of the tank body 14 .

The first end 401 of the third connecting member 40 can also selectively form a sliding hole 407, and the second connecting member 38 can also selectively use a plug (not marked in the drawings) to be slidably inserted into the sliding hole 407, so that the second connecting member 38 can be slidably inserted into the sliding hole 407. The connecting member 38 can maintain linear motion when the third connecting member 40 rotates. As shown in FIG. 6 , correspondingly, the sliding holes 441 can be formed on one or both of the two opposite ends of the fourth connecting member 44 (for example, the position near the free end pivot point 443 ). The second connecting member 38 and the second limiting structure 46 can be slidably inserted into the sliding hole 441 using a pin (not marked in the drawings); therefore, when the fourth connecting member 44 rotates, the second connecting member 38 and the second limiting structure 46 are slidably inserted into the sliding hole 441 . The bit structure 46 can maintain linear motion.

In addition, the cover plate 22 may also optionally include a guide member 50, and the guide member 50 is a hollow channel.
