The noise caused by the operation is also significantly less than that of the air cooling system. It is commonly used for heat dissipation of high-power and high-heat-flux electronic equipment and has become a key technology in the development and application of electronic equipment systems.

[0003] In order to improve the space utilization and achieve the optimal refrigeration effect in a limited space, the liquid cooling source usually adopts a modular refrigeration air conditioner with a ring-shaped multi-surface air inlet. Due to the special structure of this modular air conditioner, dust, sand, and condensate water and other debris may deposit inside the air conditioner and cannot be effectively discharged, which may affect the service life of the air conditioner and even cause the air conditioner to malfunction.

[0004] The existing solution generally opens several water flow holes at the bottom of the air conditioner to discharge dirt. However, when the liquid cooling source is working, external gas can directly enter the inside of the liquid cooling source through the water flow holes, which may cause air leakage and result in poor heat exchange efficiency of the liquid cooling source. SUMMARY

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0024] like Figs. 1 to 4 The liquid cooling source shown includes a base 1 and a heat exchange component 2. The heat exchange component 2 is arranged in a ring on the base 1, and an air outlet channel 3 is formed on the inner side of the heat exchange component 2. A portion of the base 1 forms the first end face of the air outlet channel 3. The liquid cooling source also includes a sealing structure 4. A drain port 11 is provided on the base 1 forming the first end face. The sealing structure 4 is located at the drain port 11 and has both an open, connected state and a closed state. By using the sealing structure 4 to seal the drain port 11, the liquid cooling source switches to the open state when it needs to drain to ensure reliable draining, and switches to the closed state when the liquid cooling source is working. In this case, external gas cannot directly enter through the drain port 11, effectively avoiding air leakage and thus effectively ensuring the heat exchange efficiency and reliability of the liquid cooling source.

[0025] Specifically, the closed structure 4 includes a sealing plate 41, which is movably disposed on the base 1. When the closed structure 4 is in the closed state, the sealing plate 41 is attached to the base 1. At this time, the sealing plate 41 seals the drain outlet 11 by closing the end of the drain outlet 11, preventing gas from flowing through the drain outlet 11.

[0026] As an implementation, the sealing plate 41 is rotatably arranged on the side of the base 1 away from the air outlet channel 3, and when the closed structure 4 is switched to the communication state, the sealing plate 41 rotates downward of the base 1. Since the sealing plate 41 has its own weight, when the closed structure 4 is switched to the communication state, the sealing plate 41 can rotate under the action of its own weight, thereby achieving the purpose of opening the pollution outlet 11.

[0027] The sealing plate 41 is provided with a counterweight structure 42. The counterweight structure 42 is used to increase the weight of the sealing plate 41 to ensure the reliable rotation of the sealing plate 41.

[0028] At the same time, since the pollution outlet 11 is located in the air outlet channel 3, the fan of the liquid cooling source can form a negative pressure in the air outlet channel 3, so that there is also a negative pressure at the pollution outlet 11, which can adsorb the sealing plate 41 on the base 1, thereby ensuring the sealing effect of the sealing plate 41 on the pollution outlet 11 and avoiding the problem of air leakage of the pollution outlet 11.

[0029] In order to ensure the reliable sealing of the sealing plate 41 on the pollution outlet 11 and enable the closed structure 4 to be freely switched between the communication state and the closed state, the closed structure 4 further comprises a driving mechanism 43 arranged on the base 1, and the sealing plate 41 is connected to the driving mechanism 43. The driving mechanism 43 can drive the sealing plate 41 to move to achieve the closing and opening of the pollution outlet 11, thereby improving the automation degree of the liquid cooling source.

[0030] Specifically, the driving mechanism 43 comprises a magnetic force mechanism, the sealing plate 41 can close the pollution outlet 11 under the action of the magnetic force generated by the magnetic force mechanism, and the detection mechanism is electrically connected to the magnetic force mechanism. The sealing plate 41 is made of a material that can be attracted by magnetic force, or a material structure that can be attracted by magnetic force is arranged on the sealing plate 41, so that the sealing plate 41 can move under the action of the magnetic force of the magnetic force mechanism. The material that can be attracted by magnetic force includes iron and iron products, magnets, etc.

[0031] The liquid cooling source further comprises a pressure detection mechanism 5 arranged in the air outlet channel 3, and the detection mechanism can detect the pressure in the air outlet channel 3, and the pressure detection mechanism 5 is electrically connected to the driving mechanism 43. When the liquid cooling source is working normally, the pressure in the air outlet channel 3 is negative due to the action of the fan, and when the liquid cooling source stops working, the fan stops working, at which time the pressure in the air outlet channel 3 gradually increases. That is, the working state of the liquid cooling source can cause the pressure in the air outlet channel 3 to change, and the pressure detection mechanism 5 can detect the pressure in the air outlet channel 3 to determine whether the liquid cooling source stops working, and when it stops working, the magnetic force mechanism is powered off to release the sealing plate and open the pollution outlet for pollution.

[0032] The liquid cooling source further comprises a top plate 6, which is arranged on the heat exchange assembly 2, and part of the top plate 6 constitutes a second end surface of the air outlet channel 3. A communication port is arranged on the top plate 6 constituting the second end surface, and the air outlet channel 3 communicates with the outside of the liquid cooling source through the communication port. The gas outside the liquid cooling source enters the air outlet channel 3 after passing through the heat exchange assembly 2, and is finally discharged through the communication port, thereby completing the cooling of the refrigerant in the heat exchange assembly 2.

[0033] The liquid cooling source further comprises a fan 7, which is arranged at the communication port, and the fan 7 has a first rotation direction and a second rotation direction. When the fan 7 is in the first rotation direction, the flow direction of the communication port is from the air outlet channel 3 to the outside air. When the fan 7 is in the second rotation direction, the flow direction of the communication port is from the outside air to the air outlet channel 3.

[0034] The first rotation direction of the fan 7 is the forward rotation of the fan 7, and the second rotation direction of the fan 7 is the reverse rotation of the fan 7.

[0035] The pressure detection mechanism 5 is electrically connected with the fan 7. When the pressure detection mechanism 5 judges that the liquid cooling source stops, the pressure detection mechanism 5 can control the fan 7 to switch to the second rotation direction, so that the outside gas is sucked into the air outlet channel. Since the blow-off port is open, the gas can drive the impurities in the air outlet channel 3 to be blown out of the blow-off port, thereby increasing the blow-off efficiency.

[0036] The liquid cooling source further comprises a stand column 8, one end of which is arranged on the base 1 and the other end of which is arranged on the top plate 6. The stand column 8 is used to connect the top plate 6 and the base 1, thereby ensuring the reliability of the shape structure of the liquid cooling source. Preferably, the number of stand columns 8 is multiple, and each stand column 8 is arranged at a corner of the liquid cooling source.

[0037] The heat exchange assembly 2 comprises an evaporator and a condenser. The condenser is arranged in a ring shape on the base 1, and the inner side of the condenser constitutes the air outlet channel 3. The evaporator is arranged in the air outlet channel 3, and the evaporator and the condenser communicate with each other. Under the action of the fan 7, the fan 7 generates negative pressure in the air outlet channel 3, thereby forcing the gas outside the liquid cooling source to enter the air outlet channel 3 through the condenser, so as to realize the heat exchange between the gas and the refrigerant in the condenser.

[0038] The liquid cooling source further comprises a compressor, which is arranged on the base 1 and located in the air outlet channel 3. The compressor communicates with the evaporator and the condenser. The compressor, the evaporator and the condenser are sequentially connected to constitute a refrigerant heat exchange cycle.

[0039] The heat exchange component 2 further comprises a surface cooler which is annularly arranged outside the condenser.

[0040] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation to the scope of the patent of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
