Description

Technical Field

[0001] The present invention relates to the field of computers, and more particularly to a highly efficient immersion liquid cooling server and data center. Background Art

[0002] In the era of big data, the performance requirements for servers are getting higher and higher, and the heat generated by their chips has increased accordingly. Correspondingly, the heat dissipation problem has become a key issue. The usual air cooling mode can no longer meet the needs, and most solutions use water cooling to dissipate heat. At present, the immersion liquid cooling solution in the data center is a non-phase change method. It generally adopts a cabinet structure and uses an insulating coolant. It exchanges heat with an external plate heat exchanger through a water pump circulation. The other end of the plate heat exchanger has an outdoor cooling tower or chiller to provide cooling capacity, and finally realizes the step-by-step transfer of heat and discharges it to the outdoors. This solution has the following disadvantages. Because the immersion liquid cooling adopts a liquid non-phase change heat transfer method, the heat exchange efficiency is low, and the entire chassis cannot flexibly select server nodes that adapt to different loads and working conditions.

[0033] Embodiments of the present disclosure are described below. However, it should be understood that the disclosed embodiments are merely examples, and other embodiments may take various alternative forms. The drawings are not necessarily drawn to scale; certain features may be exaggerated or minimized to show the details of specific components. Therefore, the specific structural and functional details disclosed herein should not be interpreted as limiting, but merely as a representative basis for teaching those skilled in the art to use the present invention in various ways. As will be understood by those of ordinary skill in the art, the various features shown and described with reference to any one of the figures may be combined with the features shown in one or more other figures to produce embodiments that are not explicitly shown or described. The combination of features shown provides representative embodiments for typical applications. However, various combinations and modifications of features consistent with the teachings of the present disclosure may be desirable for certain specific applications or embodiments.

[0034] Based on the above objectives, a first aspect of an embodiment of the present invention provides an embodiment of a high-efficiency immersion liquid cooling server. Figure 1 Shown is a schematic diagram of the highly efficient immersion liquid cooling server.

[0035] like Figure 1 As shown in , the high-efficiency immersion liquid cooling server may include:

[0036] A box 1, wherein the box 1 is configured as a sealed structure, and a server 2 is placed in the box 1;

[0037] A first liquid 3 is placed at the bottom of the box 1 and immerses the server 2;

[0038] a second liquid 4, wherein the density of the second liquid 4 is lower than that of the first liquid 3 and the second liquid 4 is insoluble in the first liquid 3, and the second liquid 4 is placed on the upper part of the first liquid 3 and in contact with the first liquid 3;

[0039] The liquid inlet 5 and the liquid outlet 6 are arranged at the upper part of the box body 1 . The liquid inlet 5 is configured to allow the second liquid 4 to flow into the box body 1 , and the liquid outlet 6 is configured to allow the second liquid 4 to flow out of the box body 1 .

[0040] Two types of immersion cooling liquids are set in the box. The second liquid on the upper part is a non-volatile liquid with light density. The inlet and outlet of the second liquid are reserved on the left and right sides of the top of the box to form a liquid circulation with the external loop. The lower layer is a low-boiling volatile first liquid. The first liquid will undergo a phase change when heated. The two liquids form a clear boundary due to density and immiscibility. When the first liquid cools the heating components, it changes phase and turns into gas. The gas floats up to the bottom of the second liquid on the upper layer and undergoes heat exchange before turning into the first liquid again. The first liquid always circulates internally in the lower layer, and the second liquid at the top also seals the gas, solving the pollution and cost caused by the volatilization of the first liquid after it turns into gas.

[0041] The multi-node server is immersed in the first liquid and arranged in parallel. A temperature sensor is arranged inside the server to automatically adjust the flow rate of the second liquid according to the temperature signal, increase convective heat exchange, and enhance heat exchange. In addition, a selective film is installed at the liquid outlet to prevent gas volatilization, provide secondary protection, and avoid environmental pollution. The present invention achieves a significant improvement in heat exchange efficiency through phase change heat exchange and enhanced convective heat exchange, thereby ensuring the safe operation of the heat-generating components in the entire server and increasing their service life.

[0042] Through the technical solution of the present invention, the problem of uneven liquid inflow to nodes of conventional liquid-cooled servers can be avoided, the internal heat dissipation efficiency of the server can be improved, higher equipment heat exchange efficiency, higher energy efficiency ratio and lower chip surface temperature can be obtained, and the server performance can be greatly improved.

[0043] In a preferred embodiment of the present invention, it also includes:

[0044] The liquid replenishment port is arranged at the bottom of the box body, and is configured to replenish the first liquid into the box body. After the first liquid changes into gas, the gas will rise, making the total amount of the first liquid smaller. At this time, the amount of the first liquid needs to be appropriately increased through the liquid replenishment port.

[0045] In a preferred embodiment of the present invention, the first liquid is configured to undergo a phase change and become a gas when the first liquid is heated, and the gas becomes the first liquid when it is cooled. When the first liquid cools the heating component, it undergoes a phase change and becomes a gas, and the gas floats up to the bottom of the upper second liquid and undergoes heat exchange before becoming the first liquid again. The first liquid always circulates internally in the lower layer, and the second liquid at the top simultaneously seals the gas, thereby solving the pollution and cost caused by the volatilization of the first liquid after it becomes a gas.

[0046] In a preferred embodiment of the present invention, it also includes:

[0047] The selective film is arranged on the liquid outlet, and the selective film is configured to prevent the first liquid from volatilizing out of the box after being phase-changed into gas. The selective film can prevent gas volatilization, provide secondary protection, and avoid environmental pollution.

[0048] In a preferred embodiment of the present invention, it also includes:

[0049] A temperature sensor is disposed on the server, and the temperature sensor is configured to detect the temperature of the server;

[0050] The controller is configured to receive the temperature of the server detected by the temperature sensor, and adjust the flow rate of the second liquid into and out of the box body based on the temperature value. According to the received temperature sensing signal, the controller can control the electric regulating valve, and according to the control strategy, can automatically adjust the flow rate of the second liquid, increase or decrease the heat exchange between the first liquid and the second liquid, so as to match the different load requirements of the server.

[0051] The present invention adopts a high-efficiency immersion liquid cooling server solution design, so that when the internal component structure of the server is certain, the liquid phase change heat transfer and internal circulation flow can be used to avoid the problem of uneven liquid inflow in conventional liquid cooling server nodes. Convective heat transfer is enhanced by two liquids. In addition, the flow rate of the liquid inlet can be intelligently adjusted according to the temperature signal. Through optimized design, the internal heat dissipation efficiency of the server is increased by more than 30%, thereby obtaining higher equipment heat exchange efficiency, higher energy efficiency ratio and lower chip surface temperature, which greatly improves computing density and performance.
