At this point, the piston 204 is stationary in the chamber 208. When the coolant in the liquid cooling system 1 is reduced to reduce the hydraulic pressure, the magnetic repulsion generated between the first magnetic region 210 and the second magnetic region 212 pushes the piston 204, thereby injecting the coolant 22 in the chamber 208.

At this point, the piston 204 is stationary in the chamber 208. When the coolant in the liquid cooling system 1 is reduced to cause the hydraulic pressure to decrease, the magnetic repulsive force generated between the first magnetic region 210 and the second magnetic region 212 pushes the piston 204, and the second magnetic region 212 and the third magnetic region The magnetic attraction generated between 214 pulls the piston 204, thereby injecting the coolant 22 in the chamber 208 into one of the liquid cooling head 10, the radiator 12, the pump 14, the reservoir 16 and the line 18. . When the magnetic repulsion force generated between the first magnetic region 210 and the second magnetic region 212, the magnetic attraction generated between the second magnetic region 212 and the third magnetic region 214 and the hydraulic pressure generated by the coolant 22 are again balanced, the piston 204 The move will stop.

In this embodiment, the third magnetic region 214 is detachably disposed at one of the bottoms of the housing 200. When the user wants to replenish the liquid replenishing mechanism 20' with the cooling liquid 22, the third magnetic region 214 may be detached from the bottom of the housing 200 to avoid the occurrence between the second magnetic region 212 and the third magnetic region 214. The magnetic attraction hinders the replenishment of the coolant 22.

The chamber 308 is in communication with the liquid outlet 3000 and houses a coolant 32. In practical applications, the coolant 32 can be water or other liquid. The piston 304 is movably disposed in the chamber 308. The washer 306 is sleeved on the outer wall of the piston 304 and abuts against the inner wall of the housing 300. Thereby, the washer 306 prevents the coolant 32 from entering the space between the cover 302 and the piston 304.

When the liquid replenishing mechanism 30 is connected to one of the liquid cooling head 10, the radiator 12, the pump 14, the reservoir 16 and the pipe 18 in FIG. 1, the liquid outlet 3000 and the liquid cooling head 10, the radiator 12 The pump 14 and the liquid storage tank 16 are in communication with one of the pipelines 18 such that the coolant 22 in the chamber 308 can be filled to the liquid cooling head 10, the radiator 12, the pump 14, and the reservoir via the liquid outlet 3000. The tank 16 is in one of the conduits 18.

The housing 300 has a first magnetic region 310, and the piston 304 has a second magnetic region 312, wherein the position of the first magnetic region 310 corresponds to the position of the second magnetic region 312.

It should be noted that the magnetic pole of the first magnetic region 310 facing one end of the second magnetic region 312 may be an N pole or an S pole, and the magnetic pole of the second magnetic region 312 facing one end of the first magnetic region 310 may be an S pole or a N pole. Extreme, depending on the application. In this embodiment, the first magnetic region 310 can be a magnetically conductive material (eg, iron or other metal), a magnet, or an electromagnet, and the second magnetic region 312 can be a magnet.

When the liquid replenishing mechanism 30 is assembled and the chamber 308 contains the cooling liquid 32, the magnetic attraction generated between the first magnetic region 310 and the second magnetic region 312 is balanced with the hydraulic pressure generated by the cooling liquid 22. At this time, the piston 304 is stationary in the chamber 308. When the coolant in the liquid cooling system 1 is reduced to reduce the hydraulic pressure, the magnetic attraction generated between the first magnetic region 310 and the second magnetic region 312 pulls the piston 304, thereby injecting the coolant 22 in the chamber 308. The liquid cooling head 10, the radiator 12, the pump 14, the reservoir 16 and the line 18 are in one of them. In other words, the liquid replenishing mechanism 30 of the present invention can automatically replenish the cooling liquid when the cooling liquid is insufficient, thereby preventing the liquid cooling system 1 from being damaged due to insufficient cooling liquid. When the magnetic attraction generated between the first magnetic region 310 and the second magnetic region 312 and the hydraulic pressure generated by the coolant 22 are again balanced, the piston 304 stops moving.

In this embodiment, the first magnetic region 310 is detachably disposed at one of the bottoms of the housing 300. When the user wants to replenish the liquid replenishing mechanism 30 with the cooling liquid 32, the first magnetic region 310 may be detached from the bottom of the housing 300 to avoid the magnetic generated between the first magnetic region 310 and the second magnetic region 312. The suction hinders the replenishment of the coolant 32.

In summary, the present invention can selectively connect the liquid replenishing mechanism to one of the liquid cooling head, the radiator, the pump, the liquid storage tank and the pipeline, and reduce the coolant to make the hydraulic pressure in the liquid cooling system. When lowered, the liquid replenishing mechanism can use the magnetic repulsion and/or magnetic force to drive the piston to move, thereby injecting the coolant in the chamber into the liquid cooling system. In other words, the liquid replenishing mechanism of the present invention can automatically replenish the cooling liquid when the cooling liquid is insufficient, thereby preventing the cooling system from being damaged due to insufficient cooling liquid.
