Description

Technical Field

[0001] This utility model relates to the field of heat dissipation, specifically an integrated heat dissipation plate. Background Technology

[0002] With the rapid development of technology, more and more technologies are entering our lives. With the advent of big data, server equipment is also gradually being used. Server equipment requires busbars to power the entire server rack. The copper plate in the server rack is also called a busbar. The busbar generates heat when it carries a strong current.

[0003] Existing copper plates typically rely on natural heat dissipation, but this method has low heat dissipation efficiency. In the high temperatures of summer, natural heat dissipation can cause the copper plate to overheat and lead to short circuits, resulting in system crashes and significant impact. Existing technologies also include water-cooled plates for heat dissipation, but water-cooled plates have high thermal resistance and low heat dissipation efficiency. Furthermore, prolonged use requires maintenance of water-cooled plates, which is time-consuming and labor-intensive. Summary of the Invention

The busbar plate has two or more connection holes, which communicate with the flow groove, and each connection hole corresponds to a connection component. The connecting component is connected to a liquid delivery pipe and is in communication with the flow channel. By adopting the above technical solution, the problem of poor heat dissipation of existing busbars is solved. Coolant is delivered through the liquid delivery pipe. When the coolant flows through the flow channel, it absorbs the heat generated by the busbar. When the coolant flows out of the flow channel, it carries away the heat from the busbar, thereby achieving the purpose of heat dissipation for the busbar. The heat dissipation effect is good, and the structure is simple.

[0020] 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.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1 , Figure 3 and Figure 4The integrated heat sink includes a busbar plate 1. A flow channel 2 is formed through the interior of the busbar plate 1, and two or more sets of connecting components 3 are installed on one side of the busbar plate 1. Insulation and sealing components 4 are installed at both ends of the flow channel 2 to insulate and seal both ends of the flow channel 2. The busbar plate 1 has two or more connecting holes 5, which communicate with the flow channel 2, and each connecting hole 5 corresponds to a connecting component 3. A fluid delivery pipe 6 is connected to the connecting component 3, and the fluid delivery pipe 6 communicates with the flow channel 2 through the connecting component 3. In this embodiment, an insulating diamond wear-resistant layer is provided on the inner wall of the flow channel 2.

[0023] In this embodiment, the busbar plate 1 is made of copper plate, which has better thermal conductivity.

[0024] Please see Figure 1 In this embodiment, there are two sets of busbars 1, and an insulating sheet 7 is provided between the two sets of busbars 1. The two sets of busbars 1 are symmetrically arranged with respect to the insulating sheet 7. The insulating sheet 7 can prevent the busbars 1 from making contact during operation, thus avoiding the problem of short circuit.

[0025] Please see Figure 1 In this embodiment, there are two sets of connecting components 3. As a preferred embodiment, the two sets of connecting components 3 are respectively located at the two ends of the flow channel 2 near the first and second ends, ensuring that the coolant entering the flow channel 2 from the connecting components 3 flows through the entire flow channel 2 as much as possible before flowing out.

[0026] Please see Figure 3 and Figure 5 In this embodiment, the connecting assembly 3 includes: a connecting pipe 31, a fixing pipe 32, and an external pressure end cap 33. The fixing pipe 32 is fixed at the connecting hole 5. One end of the connecting pipe 31 passes through the fixing pipe 32 and the connecting hole 5 in sequence and extends into the flow channel 2. The outer wall of the connecting pipe 31 is provided with a protruding structure 35. The external pressure end cap 33 is sleeved on the outer wall of the connecting pipe 31 and is pressed against one side of the protruding structure 35. The other side of the protruding structure 35 is pressed against the end of the fixing pipe 32 away from the infusion pipeline 6. As a preferred embodiment, the outer wall of the fixing pipe 32 is provided with external threads, and the inner wall of the external pressure end cap 33 is provided with internal threads. The fixing pipe 32 and the external pressure end cap 33 are threadedly connected, and the connection between the fixing pipe 32 and the busbar plate 1 is sealed to avoid leakage at the connection between the fixing pipe 32 and the busbar plate. In addition, the connecting assembly 3 also insulates the flow channel 2 and the coolant in the flow channel 2 from the busbar plate 1.

[0027] Please see Figure 3 and Figure 5A silicone sleeve 34 is fitted onto the outer wall of the connecting pipe 31, covering the outer wall of the protruding structure 35. When the external pressure end cap 33 is pressed against one side of the protruding structure 35, the silicone sleeve 34 seals the connection between the external pressure end cap 33 and the protruding structure 35, preventing coolant leakage at the connection. When the other side of the protruding structure 35 is pressed against the end of the fixing pipe 32 away from the connecting hole 6, the silicone sleeve 34 seals the connection between the fixing pipe 32 and the protruding structure 35, further preventing coolant leakage at the connection. The silicone sleeve 34, placed between the connecting pipe 31 and the external pressure end cap 33, also provides insulation, preventing the external pressure end cap 33 from becoming conductive.

[0028] Please see Figure 5 In a preferred embodiment, the protruding structure 35 is a protruding ring. Of course, in other embodiments, the protruding structure 35 can be two or more protrusions, and the protrusions are optionally spaced equally apart.

[0029] Please see Figure 6 In this embodiment, the insulating sealing assembly 4 includes: a compression block 41, a sealing block 42, and a sealing ring 43. The sealing block 42 is installed at the end of the flow channel 2, and the sealing ring 43 is sleeved on the outer wall of the sealing block 42. The compression block 41 is provided on the side of the sealing block 42 away from the flow channel 2, and the compression block 41 is fixedly connected to the busbar plate 1. In a preferred embodiment, the compression block 42 is fixedly connected to the busbar plate 1 by bolts. The insulating sealing assembly 4 insulates and seals both ends of the flow channel 2, preventing short circuits caused by leakage of coolant inside the flow channel 2. At the same time, the insulating sealing assembly 4 itself achieves insulation, so that the flow channel 2 and the coolant inside the flow channel 2 are insulated from the busbar plate 1. While the compression block 41 is fixed to the busbar plate 1, it compresses the sealing block 42, so that the sealing block 42 stably seals the end of the flow channel 2, improving the sealing performance of the flow channel 2.

[0030] In this embodiment, the compression block 41 is a rubber block. Of course, in other embodiments, the compression block 41 can be a plastic block or other blocks with a certain degree of elasticity.

[0031] Please see Figure 1 In this embodiment, a terminal block 8 is provided on the outer side of the busbar 1.

[0032] Please see Figure 5 In this embodiment, the inner wall cross-section of the flow channel 2 is trapezoidal. The trapezoidal shape of the flow channel 2 increases the heat dissipation area, thereby enabling better heat dissipation of the busbar plate 1. In other embodiments, the inner wall cross-section of the flow channel 2 can also be square, circular, or other shapes.

[0033] Please see Figure 3 and Figure 5 In this embodiment, please refer to the specific details. Figure 4 One end of the infusion pipeline 6 is connected to the connecting pipe 31, and the other end is connected to an external liquid supply device or liquid collection device. A fastening ring 36 is provided on the outer wall of the connecting pipe 31. The connecting pipe 31 is fixedly connected to the infusion pipeline 6 through the fastening ring 36. The fastening ring 36 can fix the connecting pipe 31 to the infusion pipeline 6 and prevent leakage between the infusion pipeline 6 and the connecting pipe 31.

[0034] In practical operation, the present invention is as follows: at least one set of connecting components 3 has an external liquid supply device connected to its liquid delivery pipe 6. The coolant enters the flow channel 2 from the at least one set of connecting components 3. After flowing through the flow channel 2, the coolant is output from the liquid delivery pipe 6 of at least another set of connecting components 3 to the liquid collection device, thereby removing the heat from the busbar and achieving heat dissipation.
