In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] This embodiment provides a cabinet liquid cooling system, which can indicate the flow of liquid in each liquid cooling plate, so that operation and maintenance personnel can track the working status of the liquid cooling plate and perform timely repairs on problematic liquid cooling plates.

[0040] Specifically, Figure 1-Figure 4 As shown, the cabinet liquid cooling system includes a liquid cooling plate, a manifold and a flow state indication module. Among them, there are multiple liquid cooling plates, each of which includes a liquid inlet and a liquid outlet. The manifold includes a liquid supply pipe 100 and a liquid return pipe. The liquid supply pipe 100 is provided with multiple liquid supply branches 110, and the liquid supply branches 110 are arranged one-to-one with the liquid cooling plates, and each liquid supply branch 110 is connected to a liquid inlet. The liquid return pipe is provided with multiple liquid return branches, and the liquid return branches are arranged one-to-one with the liquid cooling plates, and each liquid return branch is connected to a liquid outlet. A flow state indication module is correspondingly arranged for each liquid supply branch 110, and the flow state indication module is used to indicate the flow state of the coolant in each liquid supply branch 110.

[0041] When the cabinet liquid cooling system is working, the low-temperature coolant enters the liquid supply pipe 100 through the inlet of the liquid supply pipe 100, and then flows into the corresponding liquid cooling plate from the liquid supply branch pipe 110. After the coolant in the liquid cooling plate exchanges heat with the components that need to dissipate heat, it flows into the return pipe from the liquid outlet of the liquid cooling plate through the return branch pipe, and the high-temperature coolant flows out through the outlet of the return pipe. In this process, the flow state indication module can indicate the flow state of the coolant in each liquid supply branch pipe 110, and the coolant in the liquid supply branch pipe 110 will flow into the corresponding liquid cooling plate. Therefore, the flow state indication module is used to monitor the flow state of the liquid in each liquid cooling plate, which is convenient for the operation and maintenance personnel to track the working state of the liquid cooling plate, and can also promptly find the problematic liquid cooling plate so that the liquid cooling plate can be promptly repaired, thereby improving the operation and maintenance reliability and maintenance timeliness of the cabinet liquid cooling system.

[0042] It is worth noting that the high-temperature coolant flowing out of the outlet of the return pipe will exchange heat with the refrigeration equipment, so that the temperature of the coolant is reduced and then transported to the liquid supply pipe 100 to achieve circulating cooling.

[0043] Optionally, the liquid supply branch pipe 110 and the liquid inlet, as well as the liquid return branch pipe and the liquid outlet can be connected via a soft connecting pipe.

[0044] Optionally, continue to see Figure 2 and Figure 4 The flow state indication module includes a transmission shaft 210, an impeller 220 and an indicator 230. The transmission shaft 210 is sealed and penetrates the wall of the liquid supply pipe 100, and the transmission shaft 210 can rotate around its own axis. The impeller 220 is arranged at one end of the transmission shaft 210 placed in the liquid supply pipe 100, and the liquid in the liquid supply pipe 100 enters the liquid supply branch pipe 110 corresponding to the impeller 220 after passing through the impeller 220. The indicator 230 is arranged at one end of the transmission shaft 210 placed outside the liquid supply pipe 100, and the indicator 230 rotates synchronously with the impeller 220.

[0045] The working principle of the flow state indication module is as follows:

[0046] The coolant flowing into the liquid supply branch pipe 110 will first pass through the impeller 220 and then enter the corresponding liquid supply branch pipe 110. Whenever the coolant passes through the impeller 220, it will drive the impeller 220 to rotate. The rotation of the impeller 220 will drive the transmission shaft 210 connected thereto to rotate. The rotation of the transmission shaft 210 will drive the indicator 230 connected thereto to rotate. The rotation of the indicator 230 indicates that the coolant in the liquid cooling plate connected to the liquid supply branch pipe 110 flows normally.

[0047] The flow state indication module has a simple structure and is easy to install, and the indication sensitivity of the indicator 230 is relatively good.

[0048] Further, see Figure 2 In order to reduce the obstruction of the impeller 220 on the coolant entering the liquid supply branch 110, in this embodiment, the liquid supply pipe 100 includes a confluence chamber 101 extending along the length direction of the liquid supply pipe 100 and a plurality of branch chambers 102 connected to the confluence chamber 101, the confluence chamber 101 is connected to the inlet of the liquid supply pipe 100, the liquid supply branch 110 is connected to the branch chamber 102, and the impeller 220 is arranged in the branch chamber 102. That is, the coolant entering from the inlet of the liquid supply pipe 100 will enter the confluence chamber 101, and after being decompressed and uniformly flowed by the confluence chamber 101, it will enter each branch chamber 102, and then enter the corresponding liquid supply branch 110. In addition, the impeller 220 and the liquid supply branch 110 are arranged at opposite ends of the branch chamber 102 in the direction perpendicular to the liquid supply pipe 100. In this way, the obstruction effect of the impeller 220 on the flow of the coolant is reduced, which is conducive to ensuring the flow rate of the coolant in the liquid cold plate.

[0049] In this embodiment, the direction perpendicular to the liquid supply pipe 100 is Figure 3 The arrow points in the direction.

[0050] Optionally, continue to see Figure 1 and Figure 2 In this embodiment, the liquid supply pipe 100 is arranged horizontally, and the diversion chamber 102 is arranged below the confluence chamber 101. Of course, in other embodiments, the arrangement direction of the liquid supply pipe 100 can also be other, and it can be arranged according to actual needs, and this application does not make specific limitations.

[0051] Optionally, in one possible embodiment, the indicator 230 may be a pointer. In another possible embodiment, the indicator 230 may also be an indicator wheel. In other possible embodiments, the structure of the indicator 230 may also be other, which can be set according to actual needs, and the present application does not make specific limitations.

[0052] Furthermore, the indicator 230 may be coated with a striking color, such as red, for easy observation.

[0053] Further, see Figure 4 The outer cover of the indicator 230 is provided with a transparent protective cover 240. By providing the transparent protective cover 240, on the one hand, it can ensure that the state of the indicator 230 can be observed through the transparent protective cover 240, so as to monitor the flow state of the coolant in the liquid cooling plate; on the other hand, the indicator 230 can be protected, reducing the risk of damage to the indicator 230.

[0054] Further, see Figure 1 and Figure 3In a possible embodiment, a first automatic exhaust valve 300 is provided at the end of the liquid supply pipe 100. By providing the first automatic exhaust valve 300, the excess gas in the liquid supply pipe 100 can be automatically exhausted, so that the liquid supply pipe 100 is filled with coolant to ensure smooth flow of coolant in each liquid supply branch pipe 110.

[0055] In other possible embodiments, a second automatic exhaust valve may also be provided at the end of the liquid return pipe.

[0056] In this embodiment, a first automatic exhaust valve 300 is provided at the end of the liquid supply pipe 100, and a second automatic exhaust valve is provided at the end of the liquid return pipe.

[0057] This embodiment also provides a liquid cooling cabinet, including a cabinet body, a plurality of servers arranged in the cabinet body and the above-mentioned cabinet liquid cooling system, wherein the liquid cooling plates of the cabinet liquid cooling system are arranged in a one-to-one correspondence with the servers, and each liquid cooling plate is used to dissipate heat for a server.

[0058] Since the liquid cooling cabinet adopts the above cabinet liquid cooling system, the heat dissipation reliability is high.

[0059] Optionally, the liquid supply pipe 100 and the liquid return pipe may be fixed to the inner wall of the cabinet by bolt connection.

[0060] Furthermore, the cabinet body includes a cabinet door, and the flow state indication module of the cabinet liquid cooling system is arranged opposite to the cabinet door. By arranging the flow state indication module opposite to the cabinet door, the staff can intuitively obtain the coolant flow information in each liquid cooling plate through the flow state indication module when opening the cabinet door.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
