Description

Technical Field

[0001] The utility model relates to the field of server heat dissipation, in particular to a through pump and a server. Background Art

[0002] Currently, some data centers primarily use air cooling for server heat dissipation. However, with the increasing demand for high-density computing power and energy conservation and consumption reduction in data centers, liquid-cooled servers are gradually replacing traditional air-cooled servers. In this context, beyond simply adopting servers designed for liquid cooling, how to modify existing air-cooled servers to improve their heat dissipation performance and overall energy efficiency has become a critical issue facing those skilled in the art. Utility Model Content

[0003] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention provides a through-pump and a server, which improve the heat dissipation performance and overall energy efficiency of the server without requiring major modifications to the server.

[0004] In order to achieve the above-mentioned object, the present invention adopts the following technical solutions in the first aspect:

[0005] A through-pump for liquid cooling of a server, wherein the server comprises a mounting channel, the through-pump comprises a pump body having a liquid inlet and a liquid outlet opposite to each other, and the through-pump further comprises a fixed housing;

[0006] The fixed housing includes a first fixing seat and a connecting portion for detachably connecting to the mounting channel;

[0008] In the axial direction of the pump body, one side of the connecting portion is connected to the first fixing seat, and the connecting portion is located outside the first through hole.

[0009] The through-pump of the present application is used to modify the air-cooled server and improve the heat dissipation efficiency. The basic principle is to install the through-pump in the installation channel of the air-cooled server. After the modification, the air-cooled server performs efficient heat exchange with the heat source through the liquid cooling medium in the liquid cooling cabinet. Specifically, the through-pump includes a pump body, a fixed shell and a connecting part. The pump body is provided with a liquid inlet and a liquid outlet, and an impeller is arranged between the liquid inlet and the liquid outlet. The liquid cooling medium is transported from the liquid inlet to the liquid outlet in the pump body by the action of the impeller, and then is ejected to the heat source inside the server through the coolant in the installation channel, thereby enhancing heat exchange and improving the overall heat dissipation effect.

[0010] The fixed housing includes a first mounting base, whose connection portion connects to the mounting channel's mounting bracket via a snap-fit ​​structure, facilitating installation and removal. The first through-hole in the pump body can be docked with either the liquid inlet or outlet, ensuring smooth flow of the cooling medium. This design allows the through-pump to effectively utilize the existing mounting channel space within air-cooled servers, minimizing modifications to the existing structure and reducing retrofit costs.

[0011] Compared to traditional immersion liquid cooling solutions, this solution optimizes coolant flow, avoiding uneven flow and localized heat dissipation, thereby improving overall cooling efficiency. Furthermore, the direct-flow pump's housing design is compatible with the installation channel, making it suitable for a wide range of air-cooled server models. This reduces customization requirements, simplifies the modification process, and improves efficiency and operability.

[0018] The sleeve is sleeved outside the pump body, and the other side of the pump body in the axial direction is mounted on the end surface of the second fixing seat, and the second through hole is sleeved on the other of the liquid inlet and the liquid outlet.

[0019] Optionally, the fixed shell further includes a drainage sleeve arranged on the second fixing seat and surrounding the second through hole; one side of the drainage sleeve is aligned with the second fixing seat and fits with the other side to extend outward along the axial direction of the pump body.

The embodiments described in the embodiments are intended to explain the present invention and are not to be construed as limiting the present invention.

[0031] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] In the description of the present invention, unless otherwise specified, "a plurality of" means two or more, and "a number of" means one or more.

[0034] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0035] like Figure 1-4 As shown, a through pump is shown, which is used for liquid cooling of servers, and is mainly used for installation in the installation channel of the server during the process of converting an air-cooled server into a liquid-cooled server. The through pump includes a pump body 100 and a fixed shell. The pump body 100 has a relative liquid inlet 111 and a liquid outlet 112, and an impeller is provided between the liquid inlet 111 and the liquid outlet 112. When the air-cooled server modified with the through pump is immersed in the liquid cooling cabinet 510 and the liquid cooling medium completely immerses the impeller, the impeller can transport the liquid cooling medium from the liquid inlet to the liquid outlet and inject it at a certain speed toward the heat source in the air-cooled server during operation, so that the liquid cooling medium and the heat source can fully exchange heat, so as to more effectively remove heat from the inside of the server, thereby improving the overall heat dissipation efficiency.

[0036] The fixed housing includes a first fixing base 200 and a connecting portion 210 for removably connecting to the mounting channel. For example, one side of the connecting portion 210 is integrally connected to the first fixing base 200, and the other side has a connecting end. The connecting end can be removably connected to a fixing bracket within the mounting channel when the first fixing base 200 is installed within the mounting channel. For example, the connecting end can be an elastic clip 211 or a snap-fit ​​structure. Accordingly, the fixing bracket within the mounting channel is provided with a structure that is compatible with the connecting end.

[0037] For example, in the axial direction of the pump body 100 , a connection point between one side of the connecting portion 210 and the first fixing seat 200 is located outside the first through hole.

[0038] The first fixing base 200 has a mounting end surface 220, which is provided with a first through hole 221. One axial side of the pump body 100 is mounted on the mounting end surface 220, and the first through hole 221 is sleeved over one of the liquid inlet and the liquid outlet. For example, the first through hole 221 is sleeved over the liquid inlet, which extends axially outward and passes through the first through hole 221.

[0039] The inline pump in this embodiment features a first fixing base 200 that not only secures the inline pump but also adapts to and detachably connects to the installation channel of the air-cooled server. This allows for the conversion of an air-cooled server into a liquid-cooled server, effectively utilizing the space left by the fan removal in the installation channel within the air-cooled server. This not only improves space utilization but also enhances overall heat dissipation.

[0040] While existing immersion liquid cooling solutions offer better heat dissipation, they can also suffer from uneven coolant flow and poor localized heat dissipation. The inline pump in this embodiment, installed in the existing installation channel space within the air-cooled server, optimizes the coolant flow direction and velocity, effectively removing heat from the server and improving overall heat dissipation efficiency.

[0041] The pump's housing is designed to fit the installation channel, utilizing a connection structure similar to or common to the original fan module. This allows it to be compatible with a wide range of air-cooled server models and specifications, reducing customization requirements during the retrofit process. Furthermore, since no major server modifications are required, the retrofit process is relatively simple, reducing both cost and time.

[0042] For example, the first fixing base 200 includes a rectangular mounting plate and side plates surrounding the mounting plate. The four side plates are located on the same side of the mounting plate in the thickness direction, and the opposite side of the mounting plate forms the mounting end surface 220 of the first fixing base 200. A first through hole 221 is provided in the center of the mounting plate.

[0043] When one side of the pump body 100 is fixed to the mounting end surface 220, the cylindrical liquid outlet of the pump body 100 extends from the first through-hole 221 in the center of the mounting plate. Four side plates surround the liquid outlet and extend a certain distance in the direction of liquid discharge. This not only prevents turbulent flow caused by the simultaneous operation of multiple liquid outlets when multiple through-pumps are installed side by side, but also extends a certain length to adapt to the size of the mounting channel, optimizing the liquid flow path.

[0044] In some embodiments, in the radial direction along the pump body 100, the first fixing seat 200 has a size that is adapted to the installation space of the installation channel, so that when the first fixing seat 200 is installed in the installation channel, one end of the first fixing seat 200 in the radial direction is against the inner wall of the installation channel, and the connecting portion 210 at the other opposite end is cooperatively connected with the installation portion located on the inner wall of the installation channel, such as a snap-on connection.

[0045] In some embodiments, the connecting portion 210 includes an elastic clip 211. The elastic clip 211 is in the shape of a plate or sheet. In its length direction, one end of the elastic clip 211 is a root and the other end is a free end. Its length direction, that is, the extension direction, is consistent with the radial direction of the pump body 100. In the axial direction of the pump body 100, the root of the elastic clip 211 has a certain width, and one side of its width direction is integrally connected to the first fixing seat 200. The setting plane of the elastic clip 211 is almost flush with the outer surface of the first fixing seat 200, so that when it is inserted into the installation channel, the outer surface of the first fixing seat 200 can adapt to the mating surface of the installation channel, and the clip portion of the free end of the elastic clip 211 can cooperate with the limiting portion in the installation channel, thereby achieving a fixed connection between the first fixing seat 200 and the installation channel and preventing it from loosening.

[0046] For example, the width of the mounting plate is slightly larger than the diameter of the pump body 100. In the axial direction of the pump body 100, one of the side plates is a side plate, one side of which extends in the opposite direction of the mounting plate toward the liquid inlet on the other side of the pump body 100. A hollow portion is provided on the side plate, which runs from one side of the base of the elastic clip 211 to the other side, defining the elastic clip 211.

[0047] In some embodiments, the pump body 100 is further connected to a plug terminal 110, which is used to electrically connect to a power cord within the installation channel to supply power to the pump body 100. A mounting slot 213 for securing the plug terminal 110 is provided on one side of the connecting portion 210 in the radial direction of the pump body 100. The plug terminal 110 is installed in the mounting slot 213 with the plug end of the plug terminal 110 facing outward.

[0048] In some embodiments, the base of the elastic buckle 211 is provided with a side ear 212, and the mounting slot 213 is provided on the side ear 212. The peripheral wall of the plug-in terminal 110 is provided with a clamping portion adapted to the mounting slot 213. The insertion direction of the plug-in terminal 110 and the insertion direction of the elastic buckle 211 are both consistent with the radial direction of the pump body 100, which can be seen in FIG. Figure 2 .

[0049] When the through pump is inserted into the workstation in the installation channel along its radial direction, the plug-in terminal 110 can be connected to the power cord in the installation channel, and the elastic clip 211 can be connected to the limiting portion in the installation channel. For example, the limiting portion in the installation channel is a limiting groove that cooperates with the elastic clip 211.

[0050] In some embodiments, the fixed housing further includes a second fixing seat 300. The second fixing seat 300 is opposite to the mounting end surface 220 of the first fixing seat 200.

[0051] For example, a second through hole 310 is provided on the end surface of the second fixing base 300 facing the first fixing base 200, and a sleeve 320 surrounding the second through hole 310. One end of the sleeve 320 is connected to the second fixing base 300, and the other end is connected to the mounting end surface 220 of the first fixing base 200.

[0052] For example, the sleeve 320 is sleeved on the outside of the pump body 100, and the other axial side of the pump body 100 is installed on the end face of the second fixing seat 300, and the second through hole 310 is sleeved on the other of the liquid inlet and the liquid outlet.

[0053] For example, the second through hole 310 is sleeved on the liquid inlet of the pump body 100 .

[0054] In some embodiments, the connecting portion 210 is located between the first fixing seat 200 and the second fixing seat 300, and is connected to the second fixing seat 300 on the other side of the connecting portion 210 in the axial direction of the pump body 100. The connecting portion 210 and the second fixing seat 300 abut against each other to form a relatively complete fixed housing, thereby improving the overall strength of the fixed housing.

[0055] In some embodiments, the fixed housing further includes a drainage sleeve 610 disposed on the second fixing seat 300 and surrounding the second through hole 310. One side of the drainage sleeve 610 is aligned with the second fixing seat 300 and the other side is in contact with the second fixing seat 300 and extends outward along the axial direction of the pump body 100.

[0056] For example, the outward extension length of the drainage sleeve 610 is at least half of the side plate of the first fixing seat 200, and is aligned with and matched with the flow channel in the installation channel to form a relatively complete flow channel, thereby optimizing the flow channel and improving the ability to pump liquid cooling medium.

[0057] In some embodiments, the fixed housing further includes a side plate 230. The side plate 230 is positioned between the first fixing seat 200 and the second fixing seat 300. In the axial direction of the pump body 100, one side of the side plate 230 is integrally connected to one of the first fixing seat 200 and the second fixing seat 300. The side plate 230 is provided with notches 231 on both sides in the radial direction of the pump body 100 for inserting fingers into for disassembly.

[0058] For example, the side plate 230 is integrally connected to the first fixing base 200 .

[0059] For example, the side plate 230 is integrally formed with a side plate on the first fixing seat 200 , and the side plate 230 is adjacent to the side plate.

[0060] In some embodiments, the through-hole pump further includes a backing plate 410. A third through hole 411 is defined in the backing plate 410. One side of the backing plate 410 in the thickness direction is in contact with the mounting end surface 220, and the other side of the backing plate 410 is connected to one side of the pump body 100 in the axial direction. The third through hole 411 is disposed over one of the liquid inlet and the liquid outlet.

[0061] For example, the third through hole 411 is sleeved on the liquid inlet.

[0062] like Figure 4 As shown, the present invention further provides a server comprising a cabinet 510, a working element 530 disposed within the cabinet 510, and the aforementioned direct-flow pump. The cabinet 510 is provided with a working fluid inlet and a working fluid outlet. The working element 530 is located between the working fluid inlet and the working fluid outlet.

[0063] A mounting channel bracket 520 is provided between the working element 530 and the working fluid inlet. The through-pump is mounted on the mounting channel bracket 520, and the connecting portion 210 is detachably connected to the mounting channel bracket 520. The liquid inlet of the pump body 100 is in communication with the working fluid inlet, and the liquid outlet of the pump body 100 faces the working element 530.

[0064] For example, the installation channel fixing frame 520 separates the working medium inlet and the air outlet. A plurality of installation stations are provided in the installation channel fixing frame 520. For example, at least one through pump is installed at one of the installation stations.

[0065] By modifying the above-mentioned straight-through pump to the installation channel fixing frame 520 of the air-cooled server, the flow channel structure in the existing air-cooled server can be fully utilized without additional modification to the internal structure of the server, so that the air-cooled server modified with the straight-through pump can be directly placed in the liquid cooling cabinet 510 and used as a liquid cooling server.

[0066] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are included within the scope of the claims.
