Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

As the power density of the devices increases, their need for cooling efficiency also increases. Taking the field of computing services as an example, with the development of cloud computing, big data and chip technologies, the power of a chip of a device in some servers can reach more than 500W, so that the heat flux density is significantly increased, and the heat dissipation requirements of the devices cannot be met by the traditional air cooling heat dissipation mode. In order to meet the heat dissipation requirements of high power density equipment, heat dissipation technologies such as immersion liquid cooling and the like are beginning to be applied in the industry. The existing cabinets for deploying equipment are generally designed according to an air-cooling heat dissipation mode, and the cabinets still have a large market share, but the related art cannot be compatible with equipment adopting immersion liquid-cooling heat dissipation in the cabinets, so that the application of the equipment adopting immersion liquid-cooling heat dissipation is greatly limited.

The embodiment of the disclosure provides a liquid cooling device and a liquid cooling system, which aim to solve at least one of the above technical problems in the prior art.

The embodiment of the present disclosure provides a liquid cooling apparatus, fig. 1 shows a schematic view of the liquid cooling apparatus provided by the embodiment of the present disclosure, and as shown in fig. 1, the liquid cooling apparatus 100 includes at least one liquid cooling module 1, and further includes a cabinet 2, a main liquid supply pipe 3, and a main liquid return pipe 4. The liquid cooling module 1 comprises a cooling box 12, a liquid inlet branch 13 and a liquid outlet branch 14. Here, the first heat-generating component 11 is a component (or equipment) that needs to be cooled. The first heat-generating component 11 may be an IT device, such as a high power density server or other high power IT devices, and the specific type of the first heat-generating component 11 is not limited by the embodiments of the disclosure.

The cooling tank 12 is configured to accommodate a cooling medium and the first heat generating component 11, and specifically, the first heat generating component 11 is disposed inside the cooling tank 12 and at least partially immersed in the cooling medium, so that the first heat generating component 11 is in direct contact with the cooling medium, and the cooling medium can absorb heat of the first heat generating component 11, thereby cooling the first heat generating component 11. It is understood that the size and shape of the cooling box 12 may be customized according to the size and shape of the first heat-generating component 11. The material of the cooling box 12 may be a metal plate, such as 304 stainless steel plate. Above the cooling box 12, interfaces for power supply, monitoring, network, etc. may also be provided, which are used to connect with the first heat generating component 11 inside the cooling box 12, and which require corresponding sealing measures to ensure that the cooling medium does not leak.

In the embodiment of the present disclosure, the cooling medium may be a phase-change cooling medium or a single-phase cooling medium, and the cooling medium does not chemically react with the cooling tank 12, the first heat generating component 11, and the like. Wherein, the phase-change cooling medium can be low boiling point fluoride, etc., and the single-phase cooling medium can be high boiling point fluoride, silicon oil, etc.

The liquid inlet branch 13 and the liquid outlet branch 14 are respectively communicated with the cooling box 12, external cooling media can flow into the cooling box 12 through the liquid inlet branch 13, and the cooling media in the cooling box 12 can flow out of the cooling box 12 through the liquid outlet branch 14 after absorbing heat, so that circulation of the cooling media is realized. Particularly, liquid cooling module 1 sets up in the inside of the cabinet body 2, and main feed pipe 3 and main liquid return pipe 4 can penetrate the inside of the cabinet body 2, and main feed pipe 3 communicates with liquid inlet branch 13 of liquid cooling module 1, and main liquid return pipe 4 communicates with liquid outlet branch 14 of liquid cooling module 1. Cooling medium can flow into the liquid inlet branch 13 of each liquid cooling module 1 through the main liquid supply pipe 3 and then flow into the cooling box 12 through the liquid inlet branch 13; the cooling medium in the cooling box 12 flows into the main liquid return pipe 4 through the liquid outlet branch 14 and is discharged through the main liquid return pipe 4, so that the circulation of the cooling medium is realized.

The liquid cooling apparatus 100 provided by the embodiment of the present disclosure includes a cooling module, which can package a heat generating component to be cooled in the cooling box 12, and realize a circulation process of an external cooling medium in the cooling box 12 through the liquid inlet branch 13 and the liquid outlet branch 14, so as to cool the heat generating component. It can be seen that each liquid cooling module 1 in the above liquid cooling apparatus 100 may be a relatively independent immersion cooling system, and heat generating components using immersion liquid cooling may be arranged in the cabinet without greatly modifying the existing cabinet, which is helpful for popularization and use of components with high power density.

In the embodiment of the present disclosure, the position of the liquid inlet branch 13 may be higher than the position of the liquid outlet branch 14, so as to ensure that the inside of the cooling box 12 can always retain a certain height of the cooling medium, so that the first heat generating component 11 may be at least partially immersed in the cooling medium, and the cooling efficiency of the first heat generating component 11 is improved.

Fig. 2 is a schematic diagram of a liquid cooling module according to an embodiment of the disclosure, and as shown in fig. 2, the cooling box 12 includes a bottom plate 121, a top plate 122, and a plurality of side plates. It is to be understood that the number of side plates of the cooling box 12 may be determined based on the shape of the cooling box 12, for example, when the cooling box 12 is shaped as a rectangular parallelepiped, the cooling box 12 may include 4 side plates.

The first heat generating component 11 is placed on the bottom plate 121. Here, the first heat-generating component 11 may be directly fixed on the bottom plate 121, and the first heat-generating component 11 may also be disposed on the bottom plate 121 through some medium (e.g., a pad), and the embodiment of the present disclosure does not specifically limit the manner in which the first heat-generating component 11 is disposed on the bottom plate 121.

The liquid inlet branch 13 and the liquid outlet branch 14 are arranged on corresponding side plates in the cooling box 12, external cooling media can flow into the cooling box 12 through the liquid inlet branch 13, and the cooling media in the cooling box 12 can flow out of the cooling box 12 through the liquid outlet branch 14 after absorbing heat, so that circulation of the cooling media is realized. It should be noted that the liquid inlet branch 13 and the liquid outlet branch 14 may be disposed on the same side plate of the cooling box 12, for example, as shown in fig. 2, the side plates of the cooling box 12 include a first side plate 123, and the liquid inlet branch 13 and the liquid outlet branch 14 may be disposed on the first side plate 123. Of course, the liquid inlet branch 13 and the liquid outlet branch 14 may be disposed on different side plates of the cooling box 12, for example, as shown in fig. 2, a second side plate 124 is further included in a plurality of side plates of the cooling box 12, the liquid inlet branch 13 is disposed on the first side plate 123, and the liquid outlet branch 14 is disposed on the second side plate 124.

Alternatively, the position of the liquid outlet branch 14 may be higher than the first heat generating component 11 in the same cooling module, which may ensure that the cooling medium retained by the cooling tank 12 is higher than the first heat generating component 11, so that the first heat generating component 11 is completely immersed in the cooling medium, further improving the cooling efficiency of the first heat generating component 11.

In the disclosed embodiment, as shown in FIG. 2, the cooling box 12 further includes a partition 125. The partition 125 may guide a flow direction of the cooling medium in the cooling box 12, and specifically, the partition 125 is disposed between the top plate 122 and the bottom plate 121, the partition 125 may partition the interior of the cooling box 12 into a first cavity 126 and a second cavity 127, and the first cavity 126 and the second cavity 127 may communicate with each other. Wherein, the first cavity 126 is located between the bottom plate 121 and the partition 125, the second cavity 127 is located between the top plate 122 and the partition 125, the liquid inlet branch 13 is communicated with the first cavity 126, and the liquid outlet branch 14 is communicated with the second cavity 127, it can be understood that the first heat generating component 11 is placed inside the first cavity 126. External cooling medium can flow into the first cavity 126 of the cooling tank 12 through the liquid inlet branch 13, so that the first heating component 11 is completely immersed in the cooling medium, and after the cooling medium in the first cavity 126 absorbs heat of the first heating component 11, the cooling medium can flow into the second cavity 127, and then flows out of the cooling tank 12 through the liquid outlet branch 14, so as to realize circulation of the cooling medium.

In the disclosed embodiment, the partition 125 includes a first end and a second end disposed opposite. The first end is connected with the first side plate 123, and the liquid inlet branch 13 and the liquid outlet branch 14 are disposed on the first side plate 123. The communication ports 128 of the first and second cavities 126, 127 are adjacent the second end. The above arrangement can extend the flow path of the cooling liquid in the cooling tank 12 so that the cooling medium flows completely through the first heat generating component 11 and then flows out of the cooling tank 12. As shown in fig. 2, arrows in the cooling tank 12 of fig. 2 indicate the flow path of the cooling medium, and the liquid outlet branch 14 is communicated with the second cavity 127, it can be understood that the first heat-generating component 11 is located inside the first cavity 126. The external cooling medium can flow into the first cavity 126 of the cooling tank 12 through the liquid inlet branch 13, so that the first heating component 11 is completely immersed in the cooling medium, and the cooling medium flowing into the liquid inlet branch 13 flows into the second cavity 127 through the communication port 128 after completely flowing through the first heating component 11, so that the utilization rate of the cooling medium can be significantly improved.

As shown in fig. 1, since the liquid inlet branch 13 and the liquid outlet branch 14 of each liquid cooling module 1 are located on the same side of the cooling box 12 (both disposed on the first side plate 123), the main liquid supply pipe 3 and the main liquid return pipe 4 are located on one side of the inside of the cabinet 2 close to the first side plate 123, which can simplify the structural layout in the cabinet 2.

Optionally, in the disclosed embodiment, the second side panel 124 is further included in the plurality of side panels of the cooling box 12. The second side plate 124 is adjacent to and spaced apart from the second end of the partition 125 by a predetermined distance, and the second side plate 124 and the second end enclose a communication opening 128. Specifically, as shown in fig. 1, the first side plate 123 and the second side plate 124 of the cooling box 12 are disposed opposite to each other, and when the first end of the partition 125 is connected to the first side plate 123, the second end of the partition 125 is directed toward the second side plate 124. The distance between the first side plate 123 and the second side plate 124 is greater than the distance between the first end and the second end of the partition 125. Therefore, when the first end of the partition 125 is connected with the first side plate 123, the second end of the partition 125 cannot contact the second side plate 124, so that the second side plate 124 is spaced apart from the second end of the partition 125 by a predetermined distance, thereby forming the communication port 128 between the second side plate 124 and the second end of the partition 125.

Optionally, in the disclosed embodiment, the second side panel 124 is further included in the plurality of side panels of the cooling box 12.

Specifically, the partition plate 125 has the same shape and the same size as the shape defined by the side plates of the cooling box 12, and each side of the partition plate 125 is hermetically connected to a corresponding side plate of the cooling box 12, so that a communication port 128 is formed in the partition plate 125 to communicate the first cavity 126 with the second cavity 127, wherein the communication port 128 is located in a region of the partition plate 125 near the second end.

Optionally, in the embodiment of the present disclosure, an electrically operated valve 15 is disposed on the liquid inlet branch 13, and the electrically operated valve 15 controls the flow rate of the cooling medium in the liquid inlet branch 13.
