The first chamber is provided with a movable pressure bearing 406 on the surface facing the fan assembly 1; the second chamber is provided with an air outlet communicating with the outside world; when the fan assembly 1 blows air to the pressure bearing 406, the bearing The pressing member 406 is compressed by the air pressure to compress the first chamber, and the sealing structure 405 moves in the direction of pressing the second chamber, and the cooling liquid 408 in the first chamber flows into the liquid cooling channel 4024 .

It should be noted that the sealing structure 405 in this specific embodiment may be a structure such as a sealing ring, a sealing rubber plug, etc., which are determined according to actual conditions and will not be repeated here.

The cooling liquid 408 mentioned in this specific embodiment is generally liquid cooling liquid 408 such as cooling liquid 408 and pure water.

The liquid cooling channel 4024 can be arranged on the heat dissipation body 402 or the lower cover 403 , or the liquid cooling channel 4024 can be formed in the space surrounded by the heat dissipation body 402 and the lower cover 403 , or other suitable arrangement methods.

The fan assembly 1 and the radiator assembly 4 can be arranged in the direction shown in FIG. The fins 4022 and the carrier disposed in the first through hole 4025 blow air.

In the process of using the water-cooled auxiliary heat dissipation device provided in this specific embodiment, when the heat-generating element dissipates heat efficiently, the fan assembly 1 blows air toward the radiator assembly 4, and the airflow velocity flowing through the heat dissipation fins 4022 of the heat dissipation body 402 increases, which can Realize air cooling and heat dissipation; at the same time, the fan assembly 1 can blow air to the carrier, and the larger airflow pressure acts on the surface of the carrier, so that the carrier moves in the direction of compressing the first chamber in the first through hole 4025, and the first chamber There is cooling liquid 408 in the chamber. When the pressure-bearing member 406 moves toward the direction of compressing the first chamber, the first chamber is squeezed and the cooling liquid 408 is released at the same time. The cooling liquid 408 flows out to the liquid cooling channel 4024.

At the same time, the cooling liquid 408 is heated and vaporized to realize liquid cooling and heat dissipation; The melted coolant 408 is liquefied and accumulated in the liquid flow channel due to the temperature drop, the fan assembly 1 rotates at a lower speed, and the downward redundant air volume is not enough to push the pressure-bearing part 406 to move, and the sealing structure 405 resets under the action of external force and squeezes the first A cavity pushes the cooling liquid 408 in the liquid cooling channel 4024 to flow back and be absorbed by the compression structure 407 until the pressure bearing member 406 returns to the top.

The water-cooled auxiliary heat dissipation device provided in this specific embodiment can realize liquid cooling and air-cooled heat dissipation at the same time, which can effectively improve the heat dissipation efficiency compared with only the air-cooled heat dissipation device; reduce the noise problem caused by the excessively high speed of the fan assembly 1, and improve user experience; in addition, the coolant 408 is located in the sealed first chamber, which can avoid the problem of radiator liquid leakage.

In a specific embodiment, the first through hole 4025 is provided with a compression structure 407 that can absorb or release the cooling liquid 408. When the pressure bearing 406 is compressed by the pressure force of the first chamber, the compression structure 407 is compressed to release the cooling liquid. 408 , when the pressure bearing part 406 is reset, the compression structure 407 recovers and absorbs the cooling liquid 408 .

As shown in Figure 2, the compression structure 407 is arranged in the first through hole 4025, and the compression structure 407 is filled with the coolant 408, the heat dissipation efficiency of the heating element is low, the speed of the fan assembly 1 is low, and the pressure bearing part 406 has no When moving due to the pressure of the airflow blown out by the fan assembly 1, the coolant 408 is absorbed in the compression structure 407 and does not release; the heat dissipation efficiency of the heating element is high, the speed of the fan assembly 1 is high, and the pressure bearing 406 is blown out by the fan assembly 1 When the compression structure 407 is moved downward under the pressure of the air flow, the compression structure 407 is squeezed to release the cooling liquid 408, and the cooling liquid 408 flows out into the liquid cooling channel 4024 to realize liquid cooling and heat dissipation. When the heat dissipation efficiency of the heating element is reduced, the fan assembly 1 stops blowing or the rotation speed of the fan assembly 1 is insufficient to move the pressure bearing 406, the vaporized coolant 408 is liquefied and accumulated in the liquid cooling channel 4024, and the sealing structure 405 is Under the action of air pressure or external pressure, return to the original position, squeezed by the sealing structure 405, the first chamber is compressed, the pressure-bearing part 406 moves upward, the compression structure 407 restores its original volume, and at the same time absorbs the previously released cooling liquid 408, The cooling liquid 408 in the liquid cooling channel 4024 is sucked into the compression structure 407 again.

Specifically, the compression structure 407 can be configured as a hygroscopic sponge.

When the compression structure 407 is a hygroscopic sponge, the hygroscopic sponge is arranged in the first through hole 4025, and the hygroscopic sponge absorbs the coolant 408, the heat dissipation efficiency of the heating element is low, the speed of the fan assembly 1 is low, and the pressure bearing part 406 is not affected by the fan. When the pressure of the airflow blown out by the component 1 moves, the coolant 408 is absorbed by the moisture-absorbing sponge and does not release it. When the heating element dissipates heat efficiently and the fan speed increases, the pressure-bearing part 406 moves downward under the pressure of the airflow blown out by the fan component 1 to squeeze and absorb moisture. When the sponge is used, the moisture-absorbing sponge is squeezed and deformed to release the cooling liquid 408, and the cooling liquid 408 flows out into the liquid cooling channel 4024 to realize liquid cooling and heat dissipation. When the heat dissipation efficiency of the heating element is reduced, the fan assembly 1 stops blowing or the rotation speed of the fan assembly 1 is insufficient to move the pressure bearing 406, the vaporized coolant 408 is liquefied and accumulated in the liquid cooling channel 4024, and the sealing structure 405 is Under the action of air pressure or external pressure, it is reset to its original position, squeezed by the sealing structure 405, the first chamber is compressed, the pressure-bearing part 406 moves upward, and the moisture-absorbing sponge recovers its original volume, and at the same time absorbs the cooling liquid 408 released before, so that The cooling liquid 408 in the liquid cooling channel 4024 is sucked into the hygroscopic sponge again.

Specifically, the hygroscopic sponge can be configured to have a structure similar in shape to the first through hole 4025, so that the hygroscopic sponge can completely fill the first through hole 4025, increasing the volume of the hygroscopic sponge, thereby increasing the moisture absorption capacity and improving the heat dissipation efficiency.

Of course, the compression structure 407 can also be set to be similar to the syringe structure, the coolant 408 is stored in the syringe structure, the pressure bearing member 406 is connected with the piston rod of the syringe structure, the syringe structure is arranged in the first through hole 4025, and the heating element The heat dissipation efficiency is low, and the fan speed is low. When the pressure-bearing part 406 does not move due to the airflow pressure blown out by the fan assembly 1, the coolant 408 is absorbed in the injector structure and does not release. When the heating element dissipates heat efficiently, the fan speed increases. When the pressure-bearing member 406 moves downward under the pressure of the airflow blown out by the fan assembly 1 to squeeze the piston rod of the syringe structure, the piston rod moves downward, squeezing the cooling liquid 408 in the syringe structure, so that the cooling liquid 408 flows out to the liquid cooling channel Inside the 4024, liquid cooling is realized. When the heat dissipation efficiency of the heating element is reduced, the fan assembly 1 stops blowing or the rotation speed of the fan assembly 1 is insufficient to move the pressure bearing 406, the vaporized coolant 408 is liquefied and accumulated in the liquid cooling channel 4024, and the sealing structure 405 is Under the action of air pressure or external pressure, return to the original position, squeezed by the sealing structure 405, the first chamber is compressed, the pressure-bearing part 406 moves upward, the piston rod of the syringe structure returns to the original position, and at the same time absorbs the previously released coolant 408 , the cooling liquid 408 in the liquid cooling channel 4024 is sucked into the injector structure again, and the compression structure 407 can also be other structures that meet the requirements, which will not be repeated here.

During specific use, when the heat dissipation efficiency of the heating element is low, the fan speed is low, and the pressure-bearing member 406 is not moved by the airflow pressure blown out by the fan assembly 1, the cooling liquid 408 is absorbed in the compression structure 407 and does not release , when the heating element dissipates heat efficiently, the speed of the fan assembly 1 increases, and the pressure-bearing member 406 moves downward under the pressure of the airflow blown out by the fan assembly 1 to squeeze the first chamber, the compression structure 407 is squeezed to release the cooling liquid 408, so that the cooling The liquid 408 flows out into the liquid cooling channel 4024, the cooling liquid 408 is heated and vaporized, the compression structure 407 continues to release the cooling liquid 408, the cooling liquid 408 flowing through the liquid cooling channel 4024 continues to flow into the annular chamber, and the gasified cooling liquid 408 can also flow to the annular chamber to realize liquid cooling and heat dissipation. When the fan assembly 1 rotates at a high speed and the pressure-bearing member 406 presses the first chamber downward, the pressure in the first chamber increases due to the cooling fluid 408 released while the first chamber is being squeezed and vaporized by heat. The sealing structure 405 moves in the direction of squeezing the second chamber, so that the space in the first chamber in the annular chamber increases, so that the cooling liquid 408 enters the annular space between the columnar structure 4033 and the inner wall of the second through hole 4026. chamber, the coolant 408 gasifies while absorbing heat to increase the pressure in the first chamber, and the sealing structure 405 moves to the direction of squeezing the second chamber under pressure; when the heat dissipation efficiency of the heating element decreases, the fan assembly 1 stops When the speed of the blower or the fan assembly 1 is insufficient to move the pressure-bearing part 406, the vaporized coolant 408 is cooled and liquefied, and accumulates in the liquid cooling channel 4024, and the sealing structure 405 returns to its original position under the action of air pressure or external pressure , being squeezed by the sealing structure 405, the first chamber is compressed, the pressure-bearing member 406 moves upward, the compression structure 407 restores its original volume, and at the same time absorbs the cooling liquid 408 released before, so that the cooling liquid 408 in the liquid cooling channel 4024 is again Inhaled into the compression structure 407.

During the specific use of the water-cooled auxiliary heat dissipation device in this specific embodiment, the cooling liquid 408 can flow into the annular chamber between the columnar structure 4033 of the lower cover 403 and the inner wall of the second through hole 4026 of the heat dissipation body 402, and can The contact area between the cooling liquid 408 and the lower cover 403 and the heat dissipation main body 402 is effectively increased, thereby improving heat dissipation efficiency.

In order to make the sealing structure 405 reset smoothly, an elastic member 404 may be provided to provide power for resetting the sealing structure 405 . One end of the elastic member 404 abuts against the sealing structure 405 , and the other end abuts against the upper cover 401 .

As shown in Figure 3, the upper cover 401 and the lower cover 403 are fastened on opposite ends of the heat dissipation body 402 respectively. When it is not enough to move the pressure bearing part 406, the sealing structure 405 is reset to its original position under the action of the elastic force of the elastic part 404. Entering the second chamber through the air outlet, the sealing structure 405 moves toward the first chamber, and squeezes the first chamber to increase the air pressure in the first chamber until the pressure-bearing member 406 faces the side of the first chamber The pressure received is greater than the pressure on the side of the pressure bearing 406 facing the fan assembly 1, the pressure bearing 406 moves to the side close to the fan assembly 1, the compression structure 407 recovers and absorbs the previously released cooling liquid 408, making the liquid cooling channel The coolant 408 at 4024 is sucked into the compression structure 407 again. When the pressure-bearing member 406 moves downwards and squeezes the first chamber under the pressure of the airflow blown out by the fan assembly 1, the cooling fluid 408 that is released while the first chamber is being squeezed is heated and vaporized, and the air pressure in the first chamber increases. , to push the sealing structure 405 to move in the direction of squeezing the second chamber. When the sealing structure 405 moves in the direction of squeezing the second chamber, it needs to overcome the elastic force of the elastic member 404 to deform the elastic member 404.
