[0045] As shown in the drawings, Figure 1 and Figure 2As shown in the drawings, in one embodiment, the cooling mechanism 100 further comprises a filter 190, which is arranged on the first circulating pipeline 140 and located between the liquid storage device 120 and the second heat exchange end of the heat exchanger 200. Specifically, in this embodiment, the filter 190 is arranged in front of the liquid inlet of the liquid cooling device 20, which ensures the cleanliness of the cooling liquid in the subsequent pipeline, avoids impurities in the cooling liquid from entering the internal pipeline of the liquid cooling device 20, causes pipeline blockage and corrosion, prolongs the service life of the heat exchanger 240 and the liquid cooling device 20, and ensures the cooling efficiency of the liquid cooling system 10.

[0046] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in one embodiment, the cooling mechanism 100 further comprises a one-way valve 141, which is arranged on the first circulating pipeline 140 and located between the water pump 110 and the liquid cooling device 20.

[0047] As shown in the drawings, Figure 1 and Figure 2 As shown in the drawings, in one embodiment, the cooling mechanism 100 further comprises a cold storage energy storage device 130, which is located between the liquid cooling device 20 and the second heat exchange end of the heat exchanger 200. It can be understood that the liquid cooling system 10 ensures the stable temperature of the cooling liquid entering the liquid cooling device 20 through the cold storage energy storage device 130, which is not affected by the external environment, thereby ensuring the efficient operation of the liquid cooling device 20. At the same time, the first temperature sensor 131 arranged on the pipeline above the cold storage energy storage device 130 monitors the temperature change in real time and feeds back to the control device. The control device adjusts the working state of the refrigeration mechanism 200 according to the information fed back by the first temperature sensor 131, optimizes the cooling effect, and thereby prolongs the service life of the liquid cooling device 20.

[0048] Specifically, in this embodiment, the cold storage energy storage device 130 is embedded with cold storage materials, which realizes energy absorption and release by relying on the material properties of the cold storage materials, thereby ensuring the stable temperature of the cooling liquid entering the liquid cooling device 20, which is not affected by the external environment, thereby ensuring the efficient operation of the liquid cooling device 20.

[0049] It should be noted that, as shown in the drawings, Figure 1 Figure 2 Figure 3 in other embodiments, the cold storage energy storage device 130 can be omitted. The application range of the cold storage materials is not limited to the cold storage energy storage device 130. For example, the cooling liquid contains cold storage energy storage materials, so that the cooling liquid itself has the effect of energy storage, such as wax, fatty acid, polyether, etc.

[0050] Specifically, the working principle of the liquid cooling system 10 is as follows:

[0051] The refrigeration mechanism 200 first compresses the refrigerant to a high-temperature and high-pressure gaseous state through the action of the compressor 210. Then, the high-pressure gas is introduced into the condenser 220 to be condensed and heat-released and converted into a liquid state. After absorbing excess liquid through the dryer 280, the refrigerant enters the throttling expansion device 230 and then flows into the heat exchanger 240 to exchange heat with the cooling mechanism 100. Finally, the refrigerant returns to the compressor 210, thereby starting a new round of refrigeration cycle. In this process, the second temperature sensor 260 and the second pressure sensor 270 monitor the temperature and pressure conditions inside the second pipeline in real time to ensure stable operation of the system.

[0052] On the other hand, the cooling mechanism 100 of the liquid cooling system 10 drives the cooling liquid flowing out of the liquid cooling device 20 outlet into the liquid storage device 120 through the water pump 110 for storage and absorption of thermal expansion and contraction. After filtration through the filter 190, the cooling liquid enters the heat exchanger 240 pipeline to exchange heat with the refrigeration mechanism 200, and then enters the cold storage liquid storage device 120 to achieve and maintain the preset temperature standard. Finally, the cooling liquid enters the cooling pipeline of the liquid cooling device 20 to complete its cooling task and enter the next cooling cycle. During the entire operation of the cooling mechanism 100, the first temperature sensor 131 and the first pressure sensor 132 monitor the temperature and pressure changes of the cooling liquid entering the liquid cooling device 20 in real time, and the flow meter 180 monitors the flow rate in the first circulation pipeline 140. In addition, the third temperature sensor 150 and the third pressure sensor 170 also monitor the temperature and pressure of the return liquid in synchronization to ensure that the circulation state of the cooling liquid is optimal.

[0053] It should be noted that the monitoring method of all the temperature sensors and pressure sensors and the control method of the control device described above all belong to the prior art, and the present application only protects the connection relationship and positional relationship of the elements.

[0054] The present application also provides a liquid cooling device 20 comprising the liquid cooling system 10 of any one of the above embodiments.

[0055] In this embodiment, the two ends of the first circulation pipeline 140 of the liquid cooling system 10 are connected to the liquid inlet and liquid outlet of the liquid cooling device 20, respectively, so that the cooling liquid circulates in the cooling pipeline of the liquid cooling device 20 to carry away heat. The cooling liquid is driven to circulate by the water pump 110 to ensure that the liquid cooling device 20 continuously and efficiently dissipates heat and maintains stable operation of the system. At the same time, the temperature of the system is monitored in real time by the temperature sensor, and the control device is fed back, so as to adjust the liquid cooling system 10 to the optimal cooling effect, thereby prolonging the service life of the liquid cooling device 20.

[0056] Compared with the prior art, the present disclosure has at least the following advantages:

[0057] 1. The liquid cooling system integrates cooling, refrigeration and control devices to achieve efficient cooling of liquid cooling equipment. By circulating the cooling liquid in a closed loop, the device effectively absorbs and transfers heat, ensuring stable temperature of the liquid cooling equipment and improving cooling efficiency.

[0058] 2. The liquid cooling system has a built-in first temperature sensor and control device to monitor the temperature of the cooling liquid in real time. The control device controls the refrigeration mechanism by monitoring the data, and intelligently adjusts the temperature of the cooling liquid through the cooperation of the compressor, condenser, throttling expansion device and heat exchanger, reducing energy consumption and improving cooling performance.

[0059] 3. The control device dynamically adjusts the flow and temperature of the cooling liquid according to the feedback of the first temperature sensor and the operating load of each device, optimizes the efficiency of the cooling mechanism, and at the same time maintains the cooling liquid within the appropriate temperature range, effectively protecting the liquid cooling equipment and system, and prolonging the overall service life.

[0060] The above-described embodiments only express several embodiments of the present disclosure, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the disclosed patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which are within the scope of the present disclosure.
