Description

Technical Field

[0001] This utility model relates to the field of liquid cooling equipment technology, and more specifically, to a baffle plate for a liquid cooling box and a liquid cooling box. Background Technology

[0002] For equipment that generates a large amount of heat, liquid cooling can be used for heat dissipation. For example, liquid-cooled enclosures can be used in various applications such as cooling cabinets in the electronics industry, integrated circuit cooling, communication equipment room cooling, aggregation equipment room cooling, data center cooling, and energy storage battery cooling systems. Liquid-cooled enclosures utilize coolant flowing through channels within the enclosure to remove the heat generated by the equipment, achieving a good cooling effect.

[0003] In related technologies, the liquid-cooled housing includes a base plate, side plates, and a baffle plate. The left and right sides of the base plate are vertically connected to the side plates, and the front and rear sides of the base plate are vertically connected to the baffle plate. These components together form the main structure of the liquid-cooled housing. The base plate has multiple through-flow cooling channels, and the baffle plate also has cooling channels. The side of the baffle plate facing the base plate has flow channel interfaces corresponding to the cooling channels on the base plate. When the baffle plate is connected to the base plate, the flow channel interfaces of the baffle plate are connected to the cooling channels of the base plate, forming a complete cooling channel loop. To achieve better cooling performance, the cooling channels of the baffle plate can be further divided, creating a tortuous, reciprocating layout or partially altering the flow direction of the coolant.

[0004] Currently, the cooling channel partitioning method for headplates involves welding a metal block into the cooling channels to create the required structure. Since the welding area is inside the cooling channels, the channels must first be cut open from the outside of the area to be sealed before inserting the metal block through the cut and welding it in place. Welding defects can affect the sealing performance of the liquid cooling tank, potentially leading to coolant leakage and safety hazards. Utility Model Content

[0005] In order to overcome the problem of potential coolant leakage caused by welding defects in the baffle plate of the liquid cooling box in the prior art, the first aspect of this utility model provides a baffle plate for a liquid cooling box.

[0006] The second aspect of this utility model provides a liquid cooling box.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a baffle plate for a liquid cooling box, comprising a plate body and a first sealing member, wherein a first cooling channel is provided inside the plate body, and the first cooling channel is provided with multiple channel interfaces, and the first sealing member is tightly fitted to the first cooling channel to divide the first cooling channel into at least two channel segments, each of the channel segments having the channel interface.

[0008] In this invention, a first sealing component is tightly fitted into the first cooling channel, thereby dividing the first cooling channel into at least two channel segments. Each channel segment is equipped with a channel interface for assembling the liquid cooling box to form the designed channel loop. Compared to the existing method of using welded metal blocks to separate the cooling channels, this solution avoids weld seams at the separation points, reducing the overall number of weld seams and thus lowering the risk of coolant leakage.

[0009] Furthermore, it also includes fasteners, wherein the plate body has a first fixing hole, the first sealing member has a second fixing hole, and the fastener passes through the first fixing hole and is connected to the second fixing hole.

[0010] In this solution, fasteners serve to connect and position the first sealing element within the first cooling channel.

[0011] Furthermore, the first cooling channel extends along the first direction, and both ends of the first cooling channel are respectively tightly connected with second sealing components.

[0012] In this solution, the two ends of the first cooling channel can be sealed by the second sealing component, reducing the generation of weld seams and avoiding the problem of coolant leakage due to welding defects.

[0013] Furthermore, the first sealing member has a threaded blind hole facing the first direction.

[0014] In this design, the external threaded rod can be connected to the first sealing member through the first threaded blind hole, so that the first sealing member can be pushed to the installation position in the first cooling channel by the threaded rod. After installation, the threaded rod can be rotated in the opposite direction to remove it.

[0015] Furthermore, a second cooling channel is provided inside the plate body and above the first cooling channel, and the second cooling channel is connected to the channel sections located on both sides of the first sealing member.

[0016] In this solution, by setting a second cooling channel above the first cooling channel, the coolant in the first cooling channel overflows into the second cooling channel, which at least partially prolongs the coolant flow time and improves the cooling effect. At the same time, it also makes the coolant distribution from the second cooling channel into the other end of the first cooling channel more uniform.

[0017] Furthermore, the second cooling channel extends along the first direction, and both ends of the first and second cooling channels are connected to a second sealing member. The second sealing member has an upper protrusion and a lower protrusion. The upper protrusion is tightly fitted to the end of the second cooling channel, and the lower protrusion is tightly fitted to the end of the first cooling channel.

[0018] In this solution, the upper and lower protrusions of the second sealing member can simultaneously seal the ends of the first and second cooling channels.

[0019] Furthermore, the second sealing member has a chamfer at one end facing the main body of the plate.

[0020] In this solution, a chamfer is provided at one end of the second sealing element to facilitate the insertion of the second sealing element into the end of the flow channel for sealing.

[0021] Furthermore, both the first sealing element and the second sealing element are rubber blocks.

[0022] In this design, rubber blocks are used to adhere to the inner wall of the flow channel, which provides a good sealing effect.

[0023] Furthermore, the plate body has an inlet and an outlet that are connected to the first cooling channel.

[0024] In this design, an outlet and an inlet are provided to facilitate connection to an external coolant circulation system.

[0025] A liquid cooling box includes a base plate, side plates, and any of the aforementioned baffle plates. The base plate has multiple third cooling channels running through it in a front-to-back direction. The baffle plates are vertically connected to the front and rear sides of the base plate, and the side plates are vertically connected to the left and right sides of the base plate. Adjacent baffle plates and side plates are fixedly connected to each other, and each channel interface is connected to the corresponding third cooling channel.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] I. The baffle plate for liquid cooling tank of this utility model uses a first sealing component to separate the flow channel. Compared with the existing method of separating the cooling flow channel with welded metal blocks, this solution can avoid the generation of weld seams at the separation position, and can reduce the number of weld seams overall, thereby reducing the risk of coolant leakage.

[0028] Second, the baffle plate for liquid cooling tank of this utility model, by using a second separator to seal the ends of the first and second cooling channels, can avoid the problem of coolant leakage due to welding defects compared to the end sealing method.

[0029] Third, the liquid cooling box of this utility model, due to the use of the above-mentioned baffle plate for assembly, can reduce the generation of weld seams, thereby reducing the problem of coolant leakage caused by welding defects. Attached Figure Description

[0047] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0048] Example 1

[0049] refer to Figures 1 to 3This is the first embodiment of the present invention. This embodiment discloses a baffle plate for a liquid cooling box, including a plate body 1 and a first sealing member 2. The plate body 1 has a first cooling channel 11 inside, and the first cooling channel 11 has a plurality of channel interfaces 12. The first sealing member 2 is tightly fitted into the first cooling channel 11 to divide the first cooling channel 11 into at least two channel segments, and each channel segment has a channel interface 12.

[0050] In this embodiment, the first sealing element 2 is tightly fitted into the first cooling channel 11, thereby dividing the first cooling channel 11 into at least two channel segments. Compared with the existing method of dividing the cooling channel by welding metal blocks, this solution can avoid the generation of weld seams at the dividing position, and can reduce the number of weld seams overall, thereby reducing the risk of coolant leakage.

[0051] In related technologies, since the welding area is usually located inside the cooling channel, it is necessary to first cut the cooling channel from the outside of the location to be sealed, then insert the metal block through the cut and weld it in place. This processing method is relatively complex, resulting in low production efficiency and increasing the number of welds. In this embodiment, the first sealing member 2 can be inserted into the predetermined position in the first cooling channel 11 for tight fitting, thereby achieving the separation of the first cooling channel 11 and improving processing efficiency.

[0052] Specifically, when the baffle plate is placed vertically, the first cooling channel 11 extends horizontally to the inner bottom of the baffle plate, and each channel interface 12 extends horizontally to one side perpendicular to the first cooling channel 11. In this embodiment, the first sealing member 2 is installed in the middle of the first cooling channel 11, dividing the first cooling channel 11 into two different channel segments to achieve different functions of liquid inlet and outlet. The first cooling channel 11 can have an L-shaped cross-section, and the first sealing member 2 is similarly L-shaped to the first cooling channel 11. The first sealing member 2 can be made of a deformable material, and its size is slightly larger than the cross-sectional size of the first cooling channel 11, thus enabling a tight fit and sealing separation of the first cooling channel 11. The first sealing member 2 is made of a deformable and corrosion-resistant material such as rubber, providing good sealing within the first cooling channel 11. For example, silicone rubber is used when the coolant is an aqueous solution of ethylene glycol, and fluororubber is used when the coolant is a fluorine carbide solution. The rubber hardness can be selected in the range of Shore hardness 40 to 70, the rubber temperature resistance range is -40℃ to 280℃, and the rubber has an aging resistance service life of 10 years.

[0053] In some embodiments, the first sealing element 2 can be disposed at other locations in the first cooling channel 11, and the number of the first sealing elements 2 can be set according to requirements to divide the first cooling channel 11 into more channel segments to suit different channel design requirements.

[0054] refer to Figure 6 , Figure 7 and Figure 11 The baffle plate also includes a fastener 3. The main body 1 of the plate has a first fixing hole 13, and the first sealing member 2 has a second fixing hole 21. The fastener 3 passes through the first fixing hole 13 and is connected to the second fixing hole 21. The fastener 3 can play a role in connection and positioning, and reinforce the first sealing member 2 in the first cooling channel 11.

[0055] Specifically, the fastener 3 can be a pin, the diameter of which matches the first fixing hole 13 and the second fixing hole 21, to further fix the first sealing member 2. In other embodiments, the fastener 3 can also be a screw, bolt, etc., and can also be fixed by gluing, snap rings, etc.

[0056] refer to Figure 3 and Figure 12 The first cooling channel 11 extends along the first direction, and each end of the first cooling channel 11 is tightly connected with a second sealing member 4. The second sealing member 4 can be made of the same material as the first sealing member 2, such as silicone rubber or fluororubber. The second sealing member 4 can seal both ends of the first cooling channel 11, reduce the generation of weld seams, and avoid the problem of coolant leakage due to welding defects.

[0057] refer to Figure 6 , Figure 7 and Figure 11The first sealing member 2 has a threaded blind hole 22 facing the first direction. The first cooling channel 11 is provided through the first direction. Before the end of the first cooling channel 11 is closed, the first sealing member 2 can be inserted into the first cooling channel 11 from the end. Specifically, an external threaded rod is threaded into the first threaded blind hole 22 to connect with the first sealing member 2, so that the first sealing member 2 can be moved to the installation position in the first cooling channel 11 by pushing the threaded rod. After installation, the threaded rod can be rotated in the opposite direction to remove it. For example, in this embodiment, the length of the threaded rod is at least half the length of the first cooling channel 11, so that the first sealing member 2 can be pushed into any position in the first cooling channel 11 from the two ends of the opening through the threaded rod, for example, the first sealing member 2 can be installed in the middle of the first cooling channel 11. During installation, the position of the first sealing member 2 can be estimated according to the insertion depth of the threaded rod. At the same time, the position of the first sealing block can be seen through the first fixing hole 13 and the channel interface 12 to facilitate installation. Since the first cooling channel 11 is through in the first direction, it will not affect the entry and exit of the threaded rod.

[0058] refer to Figure 2 and Figure 3 In this embodiment, the plate body 1 has an inlet 15 and an outlet 16 that are connected to the first cooling channel 11. The inlet 15 and the outlet 16 are respectively located in the channel sections on both sides of the first sealing member 2, corresponding to the inlet and outlet parts of the first cooling channel 11, and the outlet 16 and the inlet 15 are provided to facilitate connection to an external coolant circulation device.

[0059] Example 2

[0060] refer to Figures 4 to 10 This is the second embodiment of the present invention. This embodiment is similar to Embodiment 1, except that in this embodiment, as... Figure 9 As shown, a second cooling channel 14 is provided inside the plate body 1 and above the first cooling channel 11. The second cooling channel 14 is connected to the channel sections located on both sides of the first sealing member 2.

[0061] Specifically, a connecting port 17 is provided between the first cooling channel 11 and the second cooling channel 14, with the two connecting ports 17 respectively located above the channel sections on both sides of the first sealing member 2. For example, when coolant enters the left channel section of the first cooling channel 11, the coolant overflows from the upper connecting port 17 into the second cooling channel 14 after filling, and then flows down from the right connecting port 17 into the right channel section of the first cooling channel 11. By setting the second cooling channel 14 above the first cooling channel 11, compared to the coolant flowing directly from left to right, this design allows for a more uniform distribution of coolant in the right channel section, thereby improving the cooling effect.

[0062] refer to Figure 9 and Figure 12 The second cooling channel 14 extends along the first direction. Both ends of the first cooling channel 11 and the second cooling channel 14 are connected to second sealing members 4. Each second sealing member 4 has an upper protrusion 41 and a lower protrusion 42. The upper protrusion 41 is tightly fitted to the end of the second cooling channel 14, and the lower protrusion 42 is tightly fitted to the end of the first cooling channel 11. The upper protrusion 41 and the lower protrusion 42 of the second sealing member 4 can simultaneously seal the ends of the first cooling channel 11 and the second cooling channel 14.

[0063] Specifically, a latch is provided between the upper protrusion 41 and the lower protrusion 42 of the second sealing member 4, and a partition inner wall is provided between the first cooling channel 11 and the second cooling channel 14. The latch engages with the side of the partition inner wall, thereby sealing the upper protrusion 41 and the lower protrusion 42 at the ends of the first cooling channel 11 and the second cooling channel 14 respectively.

[0064] refer to Figure 12 The second sealing member 4 has a chamfer 43 at one end facing the plate body 1. By providing a chamfer 43 at one end of the second sealing member 4, it is easier to insert the second sealing member 4 into the end of the flow channel for sealing.

[0065] Since a liquid cooling box typically only requires one set of inlet 15 and outlet 16, the baffle plate in this embodiment may not have inlet 15 and outlet 16 when assembled into a liquid cooling box. Of course, in other embodiments, inlet 15 and outlet 16 can also be adjusted according to actual needs.

[0066] Example 3

[0067] Reference 1 to Figure 14 This embodiment discloses a liquid cooling box, including a base plate 200, a side plate 300, and a baffle plate 100 as disclosed in Embodiments 1 and 2. The base plate 200 has a plurality of third cooling channels 201 that run through it in the front and back direction. The baffle plate 100 is vertically connected to the front and rear sides of the base plate 200, and the side plate 300 is vertically connected to the left and right sides of the base plate 200. Adjacent baffle plates 100 and side plates 300 are fixedly connected to each other. Each channel interface 12 is connected to the corresponding third cooling channel 201.

[0068] like Figure 13 As shown, the lower ends of the baffle plate 100 and the side plate 300 are connected to the base plate 200. The base plate 200, the side plate 300, and the baffle plate 100 together form the main structure of the liquid cooling box, and the coolant flows between the cooling channels of the base plate 200 and the baffle plate 100. The baffle plate 100 is of two types, using the baffle plate 100 disclosed in Embodiments 1 and 2 respectively.

[0069] refer to Figure 14 , Figure 14 This is a cross-sectional view of the flow channel at the bottom of the liquid cooling box. Taking the illustrated direction as an example, the lower part of the diagram shows the front side of the liquid cooling box, and the upper part shows the rear side. The front baffle plate 100 adopts the baffle plate 100 structure disclosed in Embodiment 1, and the rear baffle plate 100 adopts the baffle plate 100 structure disclosed in Embodiment 2. Combined with... Figure 3 and Figure 14 The coolant enters from the inlet 15 into the first cooling channel 11 on the left side of the front baffle plate 100, and then enters the corresponding third cooling channel 201 of the base plate 200 through the channel interfaces 12. The coolant in the base plate 200 flows in the direction of the arrows shown in the figure. Figure 9 and Figure 14 When the coolant enters the first cooling channel 11 of the left part of the rear baffle plate 100, it enters the second cooling channel 14 of the rear baffle plate 100 through the connecting port 17, and then enters the first cooling channel 11 of the right part through the connecting port 17 from the second channel. Then it enters the corresponding third cooling channels 201 on the right side of the bottom plate 200 from the channel interfaces 12, and finally flows out from the outlet 16 through the first cooling channel 11 of the front baffle plate.

[0070] refer to Figure 14 The side plate 300 covers the side of the bottom plate 200 and the end of the baffle plate 100 located in the first cooling channel 11. Fixing the side plate 300 further reinforces the second sealing member 4, preventing it from dislodging and improving sealing. The bottom plate 200, side plate 300, and baffle plate 100 can be connected by welding. In this embodiment of the liquid cooling box, because the baffle plate 100 disclosed in Embodiments 1 and 2 is used, the number of weld seams in the baffle plate 100 can be reduced, thereby reducing the risk of coolant leakage.
