Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat dissipation equipment, in particular to a liquid cooling water distribution device capable of precisely distributing flow. BACKGROUND

[0002] With the continuous increase of power and density of data centers, liquid cooling technology has become a mainstream solution due to its high-efficiency heat dissipation capability. In a data center liquid cooling system, a liquid cooling manifold is the "distribution center" of the cooling liquid, which precisely guides the cooling liquid to each piece of liquid cooling plate, each server cabinet, or collects the return water to the heat exchanger. Its performance directly determines the heat dissipation efficiency, reliability, energy consumption level and long-term maintenance cost of the entire cooling system.

[0003] As shown in Figure 1 , the manifold, as the terminal flow distribution unit of the liquid cooling cabinet, has a fundamental influence on the flow distribution of the liquid cooling server. Balanced distribution is the current mainstream distribution method. The current liquid cooling cabinet manifold connects the inlet and outlet of the liquid cooling server through a UQD joint and a hose.

[0004] The existing liquid cooling manifold has the following problems:

[0005] 1. The manifold does not actively balance the flow, so the flow allocated to each server cannot well meet the heat dissipation demand.

[0006] 2. When the local server is overheated or the server computing power on the entire rack is not balanced, the local high temperature will be balanced by the lower cooling liquid flowing out of other servers. At this time, the heat dissipation problem may be hidden. SUMMARY

[0007] In view of the defects in the prior art, the purpose of the present application is to provide a liquid cooling water distribution device capable of precisely distributing flow. The liquid cooling water distribution device can precisely distribute the flow of cooling liquid and can timely find the heat dissipation risk server, thereby avoiding the abnormal high temperature of the cooling liquid circuit of the individual server being balanced by the temperature of the cooling liquid circuit of the remaining normal servers, which may cause the false appearance of normal overall temperature, and ensuring active safety.

[0008] To solve the above problems, the technical scheme of the present application is as follows:

[0009] A liquid cooling water distribution device capable of precisely distributing flow, comprising a liquid cooling manifold, an electromagnetic valve and a temperature sensor, the electromagnetic valve being arranged at the water inlet of the liquid cooling manifold, and the temperature sensor being arranged at the water outlet of the liquid cooling manifold for detecting the temperature of the water outlet. The electromagnetic valve adjusts the flow of the water inlet according to the temperature data of the temperature sensor, thereby precisely distributing the flow of the cooling liquid, so that the servers with different power consumptions obtain the corresponding flow of the cooling liquid for heat dissipation.

[0010] Preferably, when the temperature sensor value is higher than the set value, the electromagnetic valve is opened, and vice versa, so as to realize accurate distribution of the cooling liquid flow.

[0011] Preferably, when the server does not work, the electromagnetic valve is completely closed.

[0012] Preferably, the temperature sensor obtains the outlet cooling liquid temperature of each server, avoids that the high-temperature outlet water is balanced by other low-temperature outlet water, and thus discovers the server with heat dissipation risk in time.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] 1. The liquid cooling water distribution device can accurately distribute the cooling liquid flow.

[0015] 2. The present application can discover the server with heat dissipation risk in time, avoid that the cooling liquid circuit of the individual server is abnormally high-temperature and balanced by the cooling liquid circuit of the remaining normal server, so as to cause the false appearance of the overall normal temperature, and ensure active safety.

[0016] 3. The cold energy is not wasted, so that the PUE of the data center can be reduced. BRIEF DESCRIPTION OF DRAWINGS

[0023] When the server of the present layer has no work, the solenoid valve can be completely closed. When the temperature sensor value is higher than the set value, the solenoid valve is opened, and vice versa, so as to realize the function of accurately distributing the cooling liquid flow, so that the overall heat dissipation efficiency of the liquid cooling server is improved.
