Among them, the immersion liquid cooling has higher cooling efficiency and better cooling effect, and is widely applied.

[0046] Please refer to Figures 1-2 The integrated liquid cooling cabinet 100 comprises a cabinet body 1, a liquid cooling device 2, a pipeline structure 3 and an electric control device 4, the inner cavity of the cabinet body 1 is divided to form a plurality of installation cavities arranged in a horizontal direction, the plurality of installation cavities comprise a first installation cavity, a second installation cavity and a third installation cavity; the liquid cooling device 2 comprises an immersion box 21 arranged in the first installation cavity, the inner cavity of the immersion box 21 is filled with cooling liquid, and is used for placing hardware equipment immersed; the pipeline structure 3 is arranged in the second installation cavity, the pipeline structure 3 is communicated with the inner cavity of the immersion box 21, and is used for communicating with an external cooling tower; the electric control device 4 is arranged in the third installation cavity, and the electric control device 4 is electrically connected with the liquid cooling device 2 and the pipeline structure 3.

[0049] It should be noted that in the actual installation of the device, the arrangement direction of the plurality of installation cavities can be the front-back direction or the left-right direction, and the utility model does not limit this.

[0050] The main heat dissipation principle of the integrated liquid cooling mechanism in the utility model is that the server or the switch and other hardware devices are placed in the liquid cooling cabinet to work, and the cabinet is injected with cooling liquid to soak the hardware devices; the cooling liquid of the liquid cooling cabinet is circulated through the external cooling tower, so that the hardware devices are cooled and cooled during work.

[0051] Further, please refer to Figure 5 and Figure 6 , the pipeline structure 3 includes a heat exchanger 31, a first flow path 32 and a second flow path 33, the first flow path 32 passes through the heat exchanger 31, and both ends of the first flow path 32 are communicated with the inner cavity of the immersion tank 21; the second flow path 33 passes through the heat exchanger 31, and both ends of the second flow path 33 are used to communicate with the external cooling tower. The second flow path 33 and the external cooling tower form a circulating loop, the low-temperature cooling liquid provided by the cooling tower passes through the heat exchanger 31 under the transportation of the second flow path 33, exchanges heat with the cooling liquid in the first flow path 32, and then is cooled again in the cooling tower, and the first flow path 32 and the immersion tank 21 form a circulating loop, the first flow path 32 leads out the cooling liquid in the immersion tank 21, obtains low-temperature cooling liquid after passing through the heat exchanger 31, and then is transported back into the immersion tank 21. It should be understood that the first flow path 32 and the second flow path 33 are two flow paths that are not communicated with each other and are independent of each other.

[0052] In the utility model, the heat exchanger 31 adopts a plate heat exchanger 31.

[0053] Specifically, the liquid inlet of the first flow path 32 corresponds to the upper part of the immersion tank 21, and the liquid outlet of the first flow path 32 corresponds to the bottom of the immersion tank 21.

[0054] Considering the compact arrangement of the space, the corresponding pipeline of the first flow path 32 and the second flow path 33 should be designed with multiple turns, so as to adapt to the installation space with smaller volume.

[0055] In order to detect the pipeline condition, temperature sensors b and / or pressure sensors a and / or flow meters c are arranged on the first flow path 32 and the second flow path 33. In the embodiment, the first flow path 32 is provided with a centrifugal pump near the liquid outlet, and the pressure sensor a and the temperature sensor b are arranged between the centrifugal pump and the corresponding liquid outlet, and the flow meter c is arranged between the liquid inlet of the first flow path 32 and the heat exchanger 31. The second flow path 33 should be provided with an automatic exhaust valve to exhaust the pipeline, and the temperature sensor b and the pressure sensor a are arranged on the liquid outlet side of the second flow path 33.

[0056] Furthermore, the first flow path 32 is provided with a first filter device 321 between the heat exchanger 31 and the immersion tank 21, and the second flow path 33 is provided with a second filter device 331 between the heat exchanger 31 and the external cooling tower. The utility model does not limit the specific structure of the filter device, which is arranged on the corresponding flow path and can filter the cooling liquid to improve the stability of the pipeline.

[0057] It should be understood that the arrangement position and the specific structure of the first filter device 321 and the second filter device 331 are determined according to the design requirements of the corresponding flow path.

[0058] Furthermore, the second flow path 33 includes a first branch flow path 33a and a second branch flow path 33b, the first branch flow path 33a passes through the heat exchanger 31 and is connected to the inner cavity of the immersion tank 21 and the external cooling tower respectively, the second branch flow path 33b is parallel to part of the first branch flow path 33a, and the two ends of the second branch flow path 33b are located on the two sides of the heat exchanger 31 respectively; the pipeline structure 3 further includes a valve structure 5, which is used to connect one of the two branch flow paths 33a and block the other. During the operation of the second flow path 33, there are two operation modes, one is to heat exchange the first flow path 32, and the other is not to heat exchange the first flow path 32 without passing through the heat exchanger 31. The valve structure 5 is an electromagnetic valve or a butterfly valve arranged on the two branch flow paths 33a, and the on-off control of the corresponding valve can realize the on-off of one of the branch flow paths, and the valve structure 5 can also be a three-way valve arranged at the intersection of the two branch flow paths 33a, and the utility model does not limit this.

[0059] The control logic of heat exchange is as follows:

[0060] The cooling liquid output from the cooling tower passes through the second flow path 33, and the heat exchanger 31 is used to heat exchange the cooling liquid in the first flow path 32 to reduce the temperature of the cooling liquid in the first flow path 32.

[0061] When the temperature of the cooling liquid in the immersion box 21 is too high, the PLC system of the system control unit sends a signal to the centrifugal pump of the first flow path 32 to increase the flow rate of the cooling liquid in the first flow path 32 and the flow rate of the cooling liquid in the second flow path 33, wherein the flow meter c and the temperature and pressure sensor a on the corresponding flow path monitor the data in real time. When the temperature of the cooling liquid in the immersion box 21 is low, the cooling tower is not needed for heat exchange, and the temperature itself can support the cooling of the hardware device, at which time the PLC control system can cut off the electric control valve on the branch flow path 33a of the heat exchanger 31 to achieve better energy saving.

[0062] In addition, a liquid level sensor is arranged in the immersion box 21, which is considered that the equipment runs for a long time and the cooling liquid is lost. The data detected by the liquid level sensor is transmitted to the PLC control system to prompt the liquid supplementing action.

[0063] Considering that the pipeline has a single water outlet orientation when circulating and conveying the liquid, which makes the low-temperature cooling liquid in the immersion box 21 not uniformly distributed, please refer to Figure 4 The liquid cooling device 2 further comprises a liquid distribution plate 24 arranged on the bottom wall of the inner cavity of the immersion box 21. The liquid distribution plate 24 has a cavity formed inside, and a plurality of water outlets 242 are arranged on the upper surface of the liquid distribution plate 24 and communicate with the cavity and are uniformly distributed. An interface 241 is arranged on the middle part of the side surface of the liquid distribution plate 24 and communicates with the cavity. The interface 241 communicates with the pipeline structure 3, that is, the cooling liquid flows into the interface, uniformly flows out from the bottom of the immersion box 21 through the plurality of water outlets 242, and covers the bottom correspondingly, so as to ensure the uniform introduction of the cooling liquid and make the hardware device uniformly cooled.

[0064] It should be noted that a filter screen is arranged at the interface 241 to filter the cooling liquid when it flows in.

[0065] Further, please refer to Figure 3The immersion box 21 is provided with an open upper end, and the inner cavity of the immersion box 21 is formed with a first cavity 211 and a second cavity 212 distributed in the up-down direction, and the second cavity 212 is used to fill the cooling liquid.
