Description

Technical Field

[0001] The utility model relates to the technical field of immersion liquid cooling and heat dissipation, in particular to a cooling medium distribution structure and a liquid cooling device. Background Art

[0002] A liquid-cooled cabinet is a cabinet that uses liquid cooling technology to cool the server. When in use, the server needs to be immersed in the coolant inside the cabinet, and most of the heat is taken away by the liquid circulating medium to achieve heat dissipation and cooling.

[0003] The liquid cooling medium of existing liquid cooling cabinets generally enters from the center of the bottom of the cabinet and cannot be quickly and evenly dispersed throughout the bottom of the cabinet, thus affecting the heat dissipation efficiency of the liquid cooling system. Due to the uneven distribution of the cooling medium, some servers may receive too much cooling, while others may receive insufficient cooling, resulting in uneven cooling, which may also cause hot spots in the cabinet and increase the risk of equipment failure. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model provides a cooling medium distribution structure and a liquid cooling device to ensure that the cooling medium can be quickly and evenly distributed to the bottom of the entire liquid cooling cabinet, improve the heat dissipation efficiency, and avoid the occurrence of hot spots.

[0005] In order to achieve the above-mentioned purpose, as one aspect of the utility model, a cooling medium distribution structure is provided, including a liquid inlet pipe, a first liquid collecting cavity and a second liquid collecting cavity. The liquid inlet pipe is used to be arranged on the outside of the liquid cooling cabinet. The first liquid collecting cavity is used to be arranged at the bottom of the liquid cooling cabinet, and the first liquid collecting cavity is connected to the liquid inlet pipe. The second liquid collecting cavity is arranged above the first liquid collecting cavity, and the bottom of the second liquid collecting cavity is connected to the top of the first liquid collecting cavity. A plurality of liquid outlets are arranged on the cavity wall of the second liquid collecting cavity, and the plurality of liquid outlets are distributed along a first direction, and the liquid outlets are used to be connected one-to-one with a plurality of servers in the liquid cooling cabinet.

[0006] Applying the above embodiment, after the cooling medium enters the first liquid collecting cavity from the liquid inlet pipe, it is first dispersed along the first direction (i.e., the length direction of the first liquid collecting cavity), undergoes the first uniform flow in the first liquid collecting cavity, then enters the second liquid collecting cavity from the first liquid collecting cavity for the second uniform flow, and finally flows to multiple servers respectively through multiple liquid outlets distributed along the first direction.

[0007] It can be understood that the cooling medium enters the second liquid collecting cavity from bottom to top, so the entry process is to first evenly cover the first liquid collecting cavity located below, and then flow upward from the second liquid collecting cavity. Therefore, when the cooling medium undergoes two uniform flows and flows out from the liquid outlet of the second liquid collecting cavity, uniform liquid discharge can be achieved at each liquid outlet along the first direction, avoiding the situation in the prior art where some servers obtain more cooling liquid and some servers obtain less cooling liquid. The cooling medium in this embodiment is evenly and quickly dispersed to the bottom of the liquid cooling cabinet, so that each server can be evenly cooled, avoiding the occurrence of hot spots, and making the server dissipate heat evenly and with high heat dissipation efficiency.

[0008] Compared with the existing technology where the coolant enters from the center of the bottom of the cabinet, the new design allows the coolant to cover the entire bottom area more quickly, thereby improving the cooling efficiency. It ensures that the cooling medium can be quickly and evenly distributed to the bottom of the entire liquid-cooled cabinet, improving the heat dissipation efficiency and avoiding hot spots.

[0009] Optionally, one of the top of the first liquid collecting chamber and the bottom of the second liquid collecting chamber is formed with a connecting structure, and the other has multiple liquid inlets, and the connecting structure is connected to the multiple liquid inlets to connect the first liquid collecting chamber and the second liquid collecting chamber.

[0010] Optionally, the communication structure is arranged at the top of the first liquid collecting cavity, and the plurality of liquid inlets are arranged at the bottom of the second liquid collecting cavity.

[0011] Optionally, the plurality of liquid inlets are arranged at equal intervals along the first direction.

[0012] Optionally, the number of the liquid inlets is greater than the number of the liquid outlets.

[0013] Optionally, the connecting structure is an opening, and a length direction of the opening is parallel to the first direction.

[0014] Optionally, the cross-sectional shape of the first liquid collecting cavity is rectangular.

[0015] Optionally, the cross-sectional shape of the second liquid collecting cavity is rectangular.

[0016] As a second aspect of the utility model, a liquid cooling device is also provided, which includes a liquid cooling cabinet and the cooling medium distribution structure described in the above embodiment, the liquid inlet pipe is arranged on the side wall of the liquid cooling cabinet, and the first liquid collecting cavity is arranged at the bottom of the liquid cooling cabinet; the liquid cooling cabinet is used to place the server.

[0017] The reasoning process of the beneficial effects of the liquid cooling device provided by the present invention and the aforementioned cooling medium distribution structure is similar and will not be repeated here.

[0018] Optionally, the liquid inlet pipe is arranged on the bottom plate of the liquid cooling cabinet.

[0019] Optionally, a base is provided in the liquid cooling cabinet, a top surface of the base is flush with a top surface of the first liquid collecting cavity, and the base is used to place the server.

[0020] Optionally, the base and the first liquid collecting cavity are integrally formed, and the base and the first liquid collecting cavity are separated by a side wall of the first liquid collecting cavity.

[0021] Optionally, the first liquid collecting cavity is arranged in the middle of the liquid cooling cabinet, and the liquid cooling cabinet is provided with the base on both sides of the first liquid collecting cavity; the liquid inlet pipe is arranged on the bottom plate of the liquid cooling cabinet; and the second liquid collecting cavity is provided with a plurality of liquid outlets corresponding to the server on each side.

[0037] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0038] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0039] As one aspect of the present invention, a cooling medium distribution structure is provided. Figures 1 to 7 As shown, the cooling medium distribution structure includes a liquid inlet pipe 101, a first liquid collecting cavity 110 and a second liquid collecting cavity 120. The liquid inlet pipe 101 is used to be arranged outside the liquid cooling cabinet 200. The first liquid collecting cavity 110 is used to be arranged at the bottom of the liquid cooling cabinet 200, and the first liquid collecting cavity 110 is connected to the liquid inlet pipe 101. The second liquid collecting cavity 120 is arranged above the first liquid collecting cavity 110, and the bottom of the second liquid collecting cavity 120 is connected to the top of the first liquid collecting cavity 110. A plurality of liquid outlets 121 are arranged on the cavity wall of the second liquid collecting cavity 120, and the plurality of liquid outlets 121 are distributed along the first direction, and the liquid outlets 121 are used to be connected one-to-one with a plurality of servers 201 in the liquid cooling cabinet 200.

[0040] Specifically, refer to Figure 2 , Figure 6 and Figure 7As shown, the first direction in this embodiment is the arrangement direction of the server 201 in the liquid cooling cabinet 200, and the heights and sizes of the plurality of liquid outlets 121 are equal, so that each liquid outlet 121 can discharge liquid at the same time (the first direction is as shown in FIG. Figure 2 double arrows).

[0041] By applying the above-mentioned embodiment, after the cooling medium enters the first liquid collecting cavity 110 from the liquid inlet pipe 101, it is first dispersed along the first direction (i.e., the length direction of the first liquid collecting cavity 110), undergoes a first uniform flow in the first liquid collecting cavity 110, and then enters the second liquid collecting cavity 120 from the first liquid collecting cavity 110 for a second uniform flow, and finally, the multiple liquid outlets 121 distributed along the first direction flow to the multiple servers 201 respectively.

[0042] It can be understood that the cooling medium enters the second liquid collecting cavity 120 from bottom to top, so the entry process is to first evenly cover the first liquid collecting cavity 110 located below, and then flow upward from the second liquid collecting cavity 120. Therefore, when the cooling medium undergoes two uniform flows and flows out from the liquid outlet 121 of the second liquid collecting cavity 120, uniform liquid discharge can be achieved from each liquid outlet 121 along the first direction, avoiding the situation in the prior art where some servers 201 obtain more cooling liquid and some servers 201 obtain less cooling liquid. The cooling medium in this embodiment is evenly and quickly dispersed to the bottom of the liquid cooling cabinet 200, so that each server 201 can be evenly cooled, avoiding hot spots, and making the heat dissipation of the server 201 uniform and efficient.

[0043] As an optional implementation of the present invention, refer to Figure 3 As shown, one of the top of the first liquid collecting cavity 110 and the bottom of the second liquid collecting cavity 120 is formed with a connecting structure, and the other has a plurality of liquid inlets 122. The connecting structure is connected to the plurality of liquid inlets 122 to connect the first liquid collecting cavity 110 and the second liquid collecting cavity 120. The cooling medium first fills the first liquid collecting cavity 110, then flows out of the first liquid collecting cavity 110 and enters the second liquid collecting cavity 120. It can be understood that the first liquid collecting cavity 110 plays a role of buffering. After being filled with the cooling medium, the cooling medium then evenly enters the second liquid collecting cavity 120 from bottom to top through the connecting structure and the liquid inlet 122. When the liquid level of the cooling medium in the second liquid collecting cavity 120 reaches the position of the liquid outlet 121, the cooling medium can flow out from the liquid outlet 121 and enter the bottom of the server 201, thereby playing a cooling role.

[0044] In a specific implementation of the present invention, the communication structure is disposed at the top of the first liquid collecting cavity 110 , and the plurality of liquid inlets 122 are disposed at the bottom of the second liquid collecting cavity 120 .

[0046] As an optional implementation of the present invention, refer to Figure 5 As shown, the number of the liquid inlets 122 is greater than the number of the liquid outlets 121 , thereby increasing the speed at which the cooling medium enters.

[0047] As an optional implementation of the present invention, refer to Figure 4 As shown, the communication structure is an opening 111 , and the opening 111 is at a first junction. The length direction of the opening 111 is parallel to the first direction.

[0048] As an optional implementation of the present invention, refer to Figure 4 As shown, the cross-sectional shape of the first liquid collecting chamber 110 is a rectangle (or a rounded rectangle).

[0049] As an optional implementation of the present invention, refer to Figure 4 As shown, the cross-sectional shape of the second liquid collecting chamber 120 is a rectangle (or a rounded rectangle).

[0050] As an optional implementation of the present invention, the second liquid collecting cavity 120 can be manufactured by blocking both ends of a square tube.

The liquid inlet pipe 101 is used to be arranged outside the liquid cooling cabinet 200. The first liquid collecting cavity 110 is used to be arranged at the bottom of the liquid cooling cabinet 200, and the first liquid collecting cavity 110 is connected with the liquid inlet pipe 101. The second liquid collecting cavity 120 is arranged above the first liquid collecting cavity 110, and the top of the first liquid collecting cavity 110 is provided with an opening 111, and the length direction of the opening 111 is parallel to the first direction. The bottom of the second liquid collecting cavity 120 is provided with a plurality of liquid inlets 122, and the opening 111 is connected with the plurality of liquid inlets 122 to connect the first liquid collecting cavity 110 and the second liquid collecting cavity 120. The second liquid collecting cavity 120 has a plurality of liquid outlets 121 disposed on the cavity wall, the plurality of liquid outlets 121 being distributed along the first direction and being used to be connected one-to-one with the plurality of servers 201 in the liquid cooling cabinet 200. Specifically, the number of the liquid inlets 122 is greater than the number of the liquid outlets 121.

[0053] The cooling medium first fills the first liquid collecting cavity 110, and then flows out of the first liquid collecting cavity 110 and enters the second liquid collecting cavity 120. It can be understood that the first liquid collecting cavity 110 acts as a cache. After being filled with the cooling medium, the cooling medium then enters the second liquid collecting cavity 120 evenly from bottom to top through the connecting structure and the liquid inlet 122. When the liquid level of the cooling medium in the second liquid collecting cavity 120 reaches the position of the liquid outlet 121, the cooling medium can flow out from the liquid outlet 121 and enter the bottom of the server 201, thereby playing a cooling role.

[0056] More specifically, in this embodiment, the liquid cooling cabinet 200 has ten server 201 placement positions, each server 201 placement position is provided with a server 201 , and therefore ten liquid outlets 121 are correspondingly provided on the second liquid collecting cavity 120 .

[0057] When the liquid cooling device provided by the embodiment of the utility model is used to cool the server 201, after the cooling medium enters the first liquid collecting cavity 110 from the liquid inlet pipe 101, it is first dispersed along the first direction (i.e., the length direction of the first liquid collecting cavity 110), performs a first uniform flow in the first liquid collecting cavity 110, and then enters the second liquid collecting cavity 120 from the first liquid collecting cavity 110 for a second uniform flow, and finally, the multiple liquid outlets 121 distributed along the first direction flow to the multiple servers 201 respectively.

[0058] It can be understood that the cooling medium enters the second liquid collecting cavity 120 from bottom to top, so the entry process is to first evenly cover the first liquid collecting cavity 110 located below, and then flow upward from the second liquid collecting cavity 120. Therefore, when the cooling medium undergoes two uniform flows and flows out from the liquid outlet 121 of the second liquid collecting cavity 120, uniform liquid discharge can be achieved from each liquid outlet 121 along the first direction, avoiding the situation in the prior art where some servers 201 obtain more cooling liquid and some servers 201 obtain less cooling liquid.

In this embodiment, the base 202 and the first liquid collecting cavity 110 are two independent structures, which are convenient for assembly and disassembly and later maintenance and cleaning.

[0061] As an optional implementation of the present invention, refer to Figure 4 The base 202 and the first liquid collecting cavity 110 are integrally formed, and the base 202 and the first liquid collecting cavity 110 are separated by the side wall of the first liquid collecting cavity 110 . The base 202 and the first liquid collecting cavity 110 are not connected, and the cooling medium will not enter the base 202 .

[0062] As an extended implementation mode of the present invention, the first liquid collecting cavity 110 can be arranged in the middle of the liquid cooling cabinet 200, and the liquid cooling cabinet 200 is provided with a base 202 on both sides of the first liquid collecting cavity 110; the liquid inlet pipe 101 is arranged on the bottom plate of the liquid cooling cabinet 200; therefore, servers 201 are placed on both sides of the second liquid collecting cavity 120, and the second liquid collecting cavity 120 is provided with multiple liquid outlets 121 corresponding to the servers 201 on each side.
