The coolant is circulated in the S-shaped heat dissipation pipe, the first guide groove and the second guide groove through the first water pump and the second water pump. When the temperature of the coolant rises and the volume increases, the anti-overflow box can effectively adjust the liquid level to avoid pipe rupture caused by excessive pressure. The air first passes through the dustproof net to filter out most of the dust, then enters the water through the air delivery pipe to clean and filter small particles of dust, and then enters the dust removal water tank to replenish air, which effectively reduces the situation where dust carried in the air adheres to the blades of the heat dissipation fan and affects the heat dissipation efficiency, ensures the long-term stable operation of the heat dissipation system, and extends the service life of the heat dissipation fan and other components.

The started heat dissipation fan 7 transports the air inside the dust removal water tank 24 through the guide air duct 23 and the air inlet 9 to the inner side of the heat dissipation bracket 5 to cool the first heat dissipation fin 6.

[0029] See also Figure 1-Figure 7One end of the first input pipe 32 away from the first heat conducting plate 3 is connected to the input end of the first water pump 16 through a hose, one end of the first output pipe 33 away from the first heat conducting plate 3 is connected to the end of the first output branch pipe 20 away from the output branch connecting pipe 19 through a hose, one end of the second input pipe 37 away from the second heat conducting plate 4 is connected to the input end of the second water pump 18 through a hose, one end of the second output pipe 38 away from the second heat conducting plate 4 is connected to the end of the second output branch pipe 21 away from the output branch connecting pipe 19 through a hose, the first water pump 16 and the second water pump 18 respectively pump the coolant inside the first heat conducting plate 3 and the second heat conducting plate 4 to the inside of the overflow prevention box 11 through the hose, and while the coolant inside the first heat conducting plate 3 is pumped away, the coolant inside the S-shaped heat dissipation pipe 22 is transported to the inside of the first heat conducting plate 3 through the first output branch pipe 20 connected with the hose, and the S-shaped heat dissipation pipe 22 extracts the coolant inside the overflow prevention box 11, thereby forming a coolant circulation.

[0030] Working principle: During use, firstly, the sealing cover 26 is opened by external force, and then water is injected into the dust removal water tank 24 through the water injection pipe 25, and the water level is above the bottom end of the air delivery pipe 28, and then the sealing cover 26 is installed on the top end of the water injection pipe 25, and then the dust-proof and breathable net 13 is taken out by external force and the coolant is injected into the anti-overflow box 11 through the pressure balance pipe 12, and then the first water pump 16 and the second water pump 18 are started by the controller 10 to fill the S-shaped heat dissipation pipe 22, the first guide groove 30 and the second guide groove 35 with the coolant inside the anti-overflow box 11. After being filled with coolant, the water level of the coolant inside the anti-overflow box 11 is located in the middle of the anti-overflow box 11, and then the dust-proof and breathable net 13 is installed inside the pressure balance pipe 12;

[0031] In a computer host that needs heat dissipation, the heat dissipation mechanism 1 is installed outside the chassis, and the side of the first heat conductive plate 3 away from the second heat dissipation fin 31 is installed on the graphics card, and the side of the second heat conductive plate 4 away from the third heat dissipation fin 36 is installed on the outside of the motherboard CPU. When the computer is started, the graphics card and CPU in the computer generate heat, and the heat generated by the graphics card is absorbed by the first heat conductive plate 3. Part of the heat absorbed by the first heat conductive plate 3 is absorbed by the coolant inside the first heat conductive plate 3, and the other part is absorbed by the third heat dissipation fin 36 and diffused into the air for heat dissipation. The heat dissipation system is turned on by the controller 10, and the first water pump 16 and the second water pump 18 respectively pump the coolant inside the first heat conductive plate 3 and the second heat conductive plate 4 to the inside of the anti-overflow box 11 through the hose, and the coolant inside the first heat conductive plate 3 is pumped away through the hose The connected first output branch pipe 20 transports the coolant in the S-shaped heat dissipation pipe 22 to the inside of the first heat conducting plate 3. The S-shaped heat dissipation pipe 22 extracts the coolant in the anti-overflow box 11, thereby forming a coolant circulation. When the coolant temperature rises, the volume increases, the liquid level in the anti-overflow box 11 rises, and the excess air in the anti-overflow box 11 is discharged through the dust-proof and breathable net 13. The coolant flowing back to the anti-overflow box 11 transfers heat to the first heat dissipation fin 6 during the process of flowing to the output branch connecting pipe 19 through the S-shaped heat dissipation pipe 22. The first heat dissipation fin 6 diffuses the heat into the air. The started heat dissipation fan 7 accelerates the air flow and discharges the air outside the first heat dissipation fin 6, thereby cooling the coolant in the S-shaped heat dissipation pipe 22. The heat dissipation working mode of the second heat conducting plate 4 is the same as the heat dissipation mode of the first heat conducting plate 3.

[0032] The started cooling fan 7 transports the air inside the dust removal water tank 24 through the guide air duct 23 to the inner side of the heat dissipation bracket 5 to cool the first heat dissipation fin 6. At this time, the air pressure inside the dust removal water tank 24 is reduced, and the external air enters the interior of the air box 29 through the filtration of the dustproof net 27. Under the action of atmospheric pressure, the air inside the air box 29 is transported to the interior of the dust removal water tank 24 through the air delivery pipe 28. Since the water level inside the dust removal water tank 24 is higher than the bottom end of the air delivery pipe 28, the air entering through the air delivery pipe 28 enters the interior of the dust removal water tank 24 to replenish air after being filtered in the water. The external air filters out most of the dust through the dustproof net 27, and then small particles of dust are filtered out through water cleaning, thereby removing dust from the air and reducing the dust carried in the air from adhering to the fan blades of the cooling fan 7 to affect the heat dissipation efficiency.
