Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structures, specifically a heat dissipation structure for a power distribution board. Background Technology

[0002] With the advent of big data, electronic products are now frequently used, and server equipment requires busbars for circuit connections. Busbars are also called busbar boards in servers, and they generate heat during prolonged use.

[0003] Existing busbars typically rely on natural heat dissipation, but this method is inefficient. In the high temperatures of summer, natural heat dissipation can cause the busbars to overheat and short-circuit, leading to system shutdowns and significant disruptions. This necessitates manual maintenance, further impacting usability. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a heat dissipation structure for a power distribution board to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A heat dissipation structure for a power distribution board, characterized in that it includes a busbar plate and a water-cooled plate, wherein the number of busbar plates is two sets, and an insulating sheet is disposed between the two sets of busbar plates; the two sets of busbar plates are symmetrically arranged relative to the insulating sheet. The busbar plate has a groove on the side away from the insulating sheet, and the water-cooling plate is installed in the groove; an insulating and heat-conducting layer is provided between the groove and the water-cooling plate; the insulating and heat-conducting layer is a diamond plating layer or an electrophoretic coating layer. The water-cooled plate is provided with at least one set of water inlet connection components and at least one set of water outlet connection components on the side away from the groove; the water inlet connection components and the water outlet connection components are respectively located at both ends of the water-cooled plate.

[0006] By adopting the above technical solution, the water-cooled plate and the busbar plate achieve insulation and efficient heat conduction simultaneously through the insulating and heat-conducting layer, enabling safe and efficient heat dissipation for the busbar plate. Furthermore, the insulating and heat-conducting layer further facilitates heat conduction, allowing the water-cooled plate to better absorb the heat generated by the busbar plate and dissipate heat effectively.

[0007] This invention is further configured such that the two water-cooled plates are either interconnected or independent. In high-power applications requiring high heat dissipation efficiency, the two water-cooled plates are configured to be independent, i.e., connected in parallel, allowing for independent heat dissipation and thus high efficiency. In low-power applications where heat dissipation efficiency is less critical, the two water-cooled plates are connected in series. Coolant flowing from one plate enters the other plate through its inlet connector, meaning the coolant flows sequentially through both plates.

[0008] This utility model is further configured such that the water inlet connection assembly includes a water inlet connection pipe and a water inlet connector; one end of the water inlet connector is connected to the water-cooled plate, and the other end is connected to the water inlet connection pipe; the water inlet connector connects the water-cooled plate and the water inlet connection pipe. The water inlet connection pipe is externally connected to a coolant supply device, and the coolant enters the water-cooled plate through the water inlet connection pipe and the water inlet connector. This design is simple in structure, low in cost, and has good sealing performance.

[0009] This utility model is further configured such that the water outlet connection assembly includes a water outlet connection pipe and a water outlet connector; one end of the water outlet connector is connected to the water-cooled plate, and the other end is connected to the water outlet connection pipe; the water outlet connector connects the water-cooled plate and the water outlet connection pipe. The water outlet connection pipe is externally connected to a coolant recovery device. The coolant, after absorbing heat in the water-cooled plate, flows out of the water-cooled plate through the water outlet connector and the water outlet connection pipe, ultimately carrying away heat and achieving heat dissipation. The structure is simple, the cost is low, and the sealing performance is good.

[0010] The present invention is further configured such that at least one set of limiting components is provided on the side of the water-cooled plate away from the groove; the limiting component includes a limiting plate, which is perpendicular to the water-cooled plate; the limiting plate is connected to the busbar plate by bolts. The limiting components limit the water-cooled plate, thereby improving its structural stability.

[0011] The present invention is further configured such that the water-cooled plate has an inlet mounting hole and an outlet mounting hole on the side away from the groove; the inlet connector is connected to the water-cooled plate through the inlet mounting hole; and the outlet connector is connected to the water-cooled plate through the outlet mounting hole.

[0012] The present invention is further provided with a sealing head at each end of the water-cooled plate, which can seal both ends of the water-cooled plate to prevent liquid from flowing out.

[0013] The present invention is further provided with a housing on the side of the busbar away from the insulating sheet; the housing can protect the busbar.

[0014] The present invention is further configured such that the cross-section of the water-cooled plate is trapezoidal. The trapezoidal design of the water-cooled plate increases the contact area with the busbar plate, facilitates installation, and reduces the likelihood of cavitation during the compression of the heat transfer medium, thereby improving its heat dissipation effect.

[0015] The present invention is further configured such that the limiting component includes a limiting plate installed on one side of the busbar plate, and the limiting plate is connected to the busbar plate by bolts.

[0016] In summary, the present invention has the following main advantages: The water-cooled plate and the busbar are insulated from each other by an insulating and thermally conductive layer, achieving efficient heat conduction while ensuring safe and efficient heat dissipation for the busbar. Furthermore, the insulating and thermally conductive layer further enhances heat conduction, allowing the water-cooled plate to better absorb the heat generated by the busbar and dissipate heat effectively. The insulating layer also prevents short circuits between the two busbars during operation. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Example 1 Please see Figures 1-5 This embodiment discloses a heat dissipation structure for a power distribution board, including a busbar plate 1 and a water-cooled plate 2. There are two sets of busbar plates 1, with an insulating sheet 3 between them. The two sets of busbar plates 1 are symmetrically arranged relative to the insulating sheet 3. A groove 4 is formed on the side of the busbar plate 1 away from the insulating sheet 3, and the water-cooled plate 2 is installed in the groove 4. An insulating and heat-conducting layer 5 is provided between the groove 4 and the water-cooled plate 2. The insulating and heat-conducting layer 5 is a diamond plating or an electrophoretic coating. Of course, the insulating and heat-conducting layer 5 is not limited to the above 3 selections; other coating structures with insulating and heat-conducting effects can also be selected. In this embodiment, the water-cooled plate 2 and the busbar plate 1 achieve insulation and efficient heat conduction simultaneously through the insulating and heat-conducting layer 5, achieving safe and efficient heat dissipation for the busbar plate 1. Furthermore, by setting the insulating and heat-conducting layer 5, heat can be better conducted, allowing the water-cooled plate 2 to better absorb the heat generated by the busbar plate 1, thus dissipating heat from the busbar plate 1.

[0021] Please see Figures 1-3 In this embodiment, at least one set of water inlet connection components 6 and at least one set of water outlet connection components 7 are provided on the side of the water-cooled plate 2 away from the groove 4; the water inlet connection components 6 and the water outlet connection components 7 are respectively located at both ends of the water-cooled plate 2.

[0022] Please see Figure 1 In this embodiment, the water inlet connection assembly 6 includes a water inlet connection pipe 61 and a water inlet connector 62; one end of the water inlet connector 62 is connected to the water-cooled plate 2, and the other end is connected to the water inlet connection pipe 61; the water inlet connector 62 connects the water-cooled plate 2 and the water inlet connection pipe 61.

[0023] Please see Figure 2 In this embodiment, the water outlet connection assembly 7 includes a water outlet connection pipe 71 and a water outlet connector 72; one end of the water outlet connector 72 is connected to the water-cooled plate 2, and the other end is connected to the water outlet connection pipe 71; the water outlet connector 72 connects the water-cooled plate 2 and the water outlet connection pipe 71, and the water outlet connector 72 is directly and tightly connected to the water outlet mounting hole 73 to avoid leakage caused by gaps at the connection.

[0024] It should be noted that the water inlet connection assembly 6 enables the coolant to enter while ensuring the sealing of the water-cooled plate 2 and the insulation between the water-cooled plate 2, the coolant, and the busbar plate 1; the water outlet connection assembly 7 enables the coolant to exit while ensuring the sealing of the water-cooled plate 2 and the insulation between the water-cooled plate 2, the coolant, and the busbar plate 1.

[0025] Please see Figure 2When applied to high-power applications, i.e. applications requiring high heat dissipation efficiency, the inlet connection component 6 and the outlet connection component 7 have the same structure. The two water-cooled plates 2 are set to be independent of each other, which can be understood as the two water-cooled plates 2 being a parallel structure. The two water-cooled plates 2 dissipate heat independently, resulting in high heat dissipation efficiency.

[0026] Please see Figure 3 In this embodiment, at least one set of limiting components 8 is provided on the side of the water-cooled plate 2 away from the groove 4. In this embodiment, there are multiple sets of limiting components 8, and these multiple sets of limiting components 8 are distributed at equal intervals along the water-cooled plate 2, forming a uniform and stable limiting effect on the water-cooled plate 2. Each limiting component 8 includes a limiting plate 81, which is perpendicular to the water-cooled plate 2; the limiting plate 81 is connected to the busbar plate 1 by bolts 82. The limiting plate 81 allows the water-cooled plate 7 to be easily fixed to one side of the busbar plate 1, avoiding the problem of the water-cooled plate 7 separating from the busbar plate 1, thereby enabling the water-cooled plate 2 to better dissipate heat from the busbar plate 1.

[0027] Please see Figure 4 In this embodiment, the water-cooled plate 2 has a water inlet mounting hole 63 and a water outlet mounting hole 73 on the side away from the groove 4; the water inlet connector 62 is connected to the water-cooled plate 2 through the water inlet mounting hole 63; the water outlet connector 72 is connected to the water-cooled plate 2 through the water outlet mounting hole 73. The water inlet mounting hole 63 facilitates the installation of the water inlet connector 62 and the water-cooled plate 2; the water inlet connector 62 and the water inlet mounting hole 63 are tightly connected to avoid leakage at the connection point; the water outlet mounting hole 73 facilitates the installation of the water outlet connector 72 and the water-cooled plate 2.

[0028] Please refer to it again. Figure 4 In this embodiment, a sealing head 9 is provided at each end of the water-cooled plate 2. The sealing head 9 can seal both ends of the water-cooled plate 2 to prevent liquid from flowing out.

[0029] Please refer to Figure 1 , Figure 2 In this embodiment, a housing 10 is provided on the side of the busbar 1 away from the insulating sheet 3, and the housing 10 can protect the busbar 1.

[0030] Please see Figure 5 In this embodiment, the cross-section of the water-cooled plate 2 is set as trapezoidal. The trapezoidal water-cooled plate 2 can increase the contact area between itself and the busbar plate 1, thereby making its heat dissipation effect better. Example 2

[0031] Please see Figure 1 , Figure 3When applied to low-power applications, where heat dissipation efficiency is required, the two water-cooled plates 2 are connected in series. The coolant flowing out of one water-cooled plate 2 enters the other water-cooled plate 2 through the water inlet connection component 6 of the other water-cooled plate 2. In other words, the coolant flows through the two water-cooled plates 2 in sequence.

[0032] Please refer to it again. Figure 1 , Figure 3 Specifically, the water outlet connection pipe 71 of one water-cooled plate 2 and the water inlet connection pipe 61 of the other water-cooled plate 2 share a U-shaped connection pipe, thereby connecting the two water-cooled plates 2 in series.

[0033] Please refer to it again. Figure 1 , Figure 3 During operation, the inlet pipe 61 of one of the water-cooled plates 2 is connected to a coolant supply device. The coolant enters the water-cooled plate 2 from the inlet pipe 61. After flowing through the water-cooled plate 2, the coolant flows from the outlet pipe 71 of the water-cooled plate 2 into the inlet connector 62 of the other water-cooled plate 2, thus entering the other water-cooled plate 2. After flowing through the other water-cooled plate 2, the coolant flows out from the outlet pipe 71 of the other water-cooled plate 2, while carrying away the heat absorbed from the two water-cooled plates 2, thereby achieving heat dissipation of the busbar board.
