Abstract
Description
Technical Field
[0001] The invention relates to the technical field of liquid cooling machines, and in particular to an immersion liquid cooling device. Background Art
[0002] Existing immersion liquid cooling cabinets generally include a cabinet body and multiple servers installed in the cabinet body. The servers in the cabinet body are generally cooled by a liquid cooling system, such as a flow equalization device for an immersion liquid cooling cabinet disclosed in a Chinese patent document with application number 202310827741.6, which specifically discloses a main pipeline horizontally placed in the liquid cooling cabinet, and a number of branch pipelines connected thereto; the branch pipelines are respectively provided with flow control structure groups, including a number of liquid distribution structures and corresponding detection devices, which can distribute coolant according to the detection results. Each branch pipeline is connected to the main pipeline, and liquid is discharged through the liquid outlet holes thereon to cool the cabinet, that is, a centralized pump is used to cool multiple servers through each branch pipeline. The flow rate of each branch pipeline is uneven, which will cause some servers to operate poorly and easily shut down automatically.
[0003] In addition, the internal structure of the existing cabinet is poorly arranged, making it difficult to arrange the liquid cooling system. When multiple servers are working in the cabinet, there may be uneven flow between the servers, resulting in a large difference in the temperature of the chips working between the servers, causing poor server operation status. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an immersion liquid cooling device which improves the uniformity of spraying on each server, reduces the temperature difference between the servers, and improves the operating state of the servers.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] An immersion liquid cooling device includes a cabinet, a cooling liquid supply mechanism, and a plurality of servers arranged in the cabinet. A flow equalizing component is provided on the top of the cabinet. A liquid cooling nozzle is provided above each server. Each of the liquid cooling nozzles is connected to the flow equalizing component through a connecting pipe, and each of the connecting pipes is provided with an on-off valve.
[0007] As a further improvement of the above technical solution:
[0008] The flow balancing component is a flow balancing disk, a liquid inlet is provided at the top center of the flow balancing disk, the coolant supply mechanism is connected to the liquid inlet, a plurality of liquid outlets are provided on the circumference of the flow balancing disk and are evenly spaced around the central axis, and each of the connecting pipes is connected to each of the liquid outlets in a one-to-one correspondence.
[0009] The flow balancing disk is in the shape of a regular polygon, and each of the liquid outlets is respectively arranged on each side of the flow balancing disk.
[0010] The liquid outlets on each side of the flow balancing disk are located at the center of the side.
[0011] The connecting pipe is perpendicular to the corresponding side of the flow balancing plate.
[0012] The on-off valve is a solenoid valve.
[0013] The immersion liquid cooling device also includes a control center. Each of the servers is provided with a temperature detection mechanism. Each of the temperature detection mechanisms and each of the solenoid valves are electrically connected to the control center.
[0014] The control center controls the opening of the corresponding solenoid valve according to the detected temperature of the temperature detection mechanism.
[0015] The cabinet is square in shape, and the servers are arranged in an array along the length direction of the cabinet.
[0016] At least two servers are arranged above each of the servers.
[0017] Compared with the prior art, the advantages of the present invention are:
[0018] The immersion liquid cooling device of the present invention comprises a flow balancing component, a connecting pipe and a liquid cooling nozzle which form a coolant flow balancing mechanism. The flow balancing component evenly distributes the coolant delivered by the coolant supply mechanism to each connecting pipe, and each connecting pipe then sprays the coolant onto each server through the liquid cooling nozzle at the liquid outlet end to cool the server. Under the even flow distribution effect of the flow balancing component, the flow rate of each connecting pipe is even and good. Under the even flow distribution effect of the coolant flow balancing mechanism, the uniformity of spraying to each server is improved, so that the temperature difference between each server is reduced, thereby improving the operating state of the server.
[0019] The immersion liquid cooling device of the present invention further includes a control center, each server is provided with a temperature detection mechanism, each temperature detection mechanism and each solenoid valve are electrically connected to the control center. The control center and the temperature detection mechanism are not shown in the accompanying drawings. The solenoid valve can control the opening and closing of a single channel. When some of the servers are not working, the cooling channel can be closed by the solenoid valve, thereby increasing the flow rate of other servers.
[0020] The immersion liquid cooling device of the present invention has a square cabinet, and the servers are arranged in an array along the length direction of the cabinet. This arrangement of the servers facilitates the arrangement of the cooling liquid flow equalization mechanism, and is well combined with the arrangement of the cooling liquid flow equalization mechanism, which is conducive to avoiding uneven flow between multiple servers in the cabinet, thereby reducing the temperature difference of the chips working between the servers, so that the servers have a good operating state.
