[0002] With the increasing popularity of electronic devices and the continuous improvement of their performance, the heat dissipation of servers has become particularly important. Although the traditional air-cooling heat dissipation method can meet the heat dissipation needs to a certain extent, its heat dissipation effect is often difficult to meet the requirements in application scenarios such as high-density server clusters, high-performance computing, and artificial intelligence. Liquid-cooled servers are a new type of heat dissipation solution. By injecting liquid (such as water or other coolants) into the server, the liquid's efficient thermal conductivity is used to remove the heat of the server through heat exchange, thereby achieving a more efficient heat dissipation effect.

[0003] However, in the actual application of liquid-cooled servers, the design of radiators still faces many challenges. As one of the core components of liquid-cooled radiators, the design of heat dissipation fins directly affects the heat dissipation efficiency. Traditional heat dissipation fin designs often have problems such as large water resistance of fins and low heat dissipation efficiency, which limits the heat dissipation performance. Especially in high-density server clusters, these problems are more prominent and seriously affect the stability and service life of the server. Therefore, we have made improvements to this and proposed a bidirectional folded fin water channel structure for the liquid-cooled server temperature plate. Summary of the invention

[0034] As recorded in the background technology, in the actual application of liquid-cooled servers, the design of the radiator still faces many challenges. The design of the heat sink, as one of the core components of the liquid-cooled radiator, directly affects the heat dissipation efficiency. The traditional heat sink design often has problems such as large water resistance of the sink and low heat dissipation efficiency, which leads to limited heat dissipation performance. Especially in high-density server clusters, these problems are more prominent and seriously affect the stability and service life of the server.

[0035] In order to solve this technical problem, the utility model provides a bidirectional folded tooth water channel structure of a temperature equalizing plate of a liquid cooling server.

[0036] Specifically, please refer to Figure 1-Figure 4 The bidirectional folded tooth water channel structure of the liquid cooling server temperature plate specifically includes:

[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] Example 1, please refer to Figure 1-Figure 4 The liquid cooling server temperature equalizer has a bidirectional folded tooth water channel structure, including a base 1, a VC temperature equalizer 4 is arranged at the bottom of the base 1, the VC temperature equalizer 4 includes a first groove 401 opened at the bottom of the base 1, a second groove 402 is opened at the top of the inner cavity of the first groove 401, and a cover plate 406 is installed in the first groove 401. The VC temperature equalizer 4 can quickly transfer the heat generated by the chip to the base 1, thereby significantly improving the heat dissipation efficiency.

[0043] Further, such as Figure 4 As shown, the outer dimensions of the second groove 402 are smaller than those of the first groove 401 , and two steps are provided at the connection between the first groove 401 and the second groove 402 , and the cover plate 406 is provided between the first groove 401 and one of the steps to limit the cover plate 406 .

[0044] Further, such as Figure 4 As shown, a rat-tail opening 404 is further provided at the bottom of the base 1 , and a rat-tail pipe 405 is installed in the rat-tail opening 404 . The rat-tail opening 404 is used to achieve communication between the second groove 402 and the rat-tail pipe 405 .

[0045] Further, such as Figure 4 As shown, a third groove 403 is further provided at the bottom of the base 1 , and the third groove 403 is communicated with the rat tail opening 404 . The third groove 403 can facilitate installation of the rat tail tube 405 in the rat tail opening 404 .

[0046] Further, such as Figure 3 As shown, a protective plate 407 is fixedly connected to one side of the cover plate 406 , and the protective plate 407 is plugged into the inner wall of the third groove 403 , so that the third groove 403 can be sealed by the protective plate 407 .

[0047] Further, such as Figure 4 As shown, a support assembly is disposed between the second groove 402 and the cover plate 406 , and the support assembly is used to support the cover plate 406 .

[0048] Further, such as Figure 4 As shown, the support assembly includes a plurality of support columns 408, one end of the support column 408 is fixedly connected to the top of the inner cavity of the second groove 402, and the other end of the support column 408 is in contact with the cover plate 406. The support column 408 can support the cover plate 406 to provide stability for the entire structure and prevent deformation such as depression caused by vacuum extraction and expansion due to heat. The support column 408 can ensure that the shape and structure of the VC temperature equalizing plate 4 can remain stable when subjected to temperature changes and pressure changes, thereby ensuring the stability and durability of the thermal conduction and heat dissipation performance.

[0050] The arrangement of the first coolant water channel and the second coolant water channel realizes the structure of the bidirectional folded tooth water channel component 3, which can increase the cross-sectional area of ​​the water channel, reduce the water flow resistance, thereby increasing the water flow speed and enhancing the efficiency of heat exchange; and enables the bidirectional folded tooth component 31 to distribute heat more evenly, improve the heat dissipation efficiency, and thus effectively reduce the temperature of the server motherboard chip; due to the reduction of water flow resistance, the overall pressure drop is also reduced, thereby improving the operating efficiency of the system, and by reducing the temperature and pressure drop, the burden on the radiator is reduced, thereby extending the service life of the radiator.

The folding tooth bodies 311 are U-shaped, and two folding tooth bodies 311 are staggered and connected together to form a bidirectional folding structure, which can increase the cross-sectional area of ​​the water channel, reduce the water flow resistance, and increase the water flow speed. Due to the reduction in water flow resistance, the overall pressure drop is also reduced, thereby improving the operating efficiency of the system. By reducing the temperature and pressure drop, the burden on the radiator is reduced, thereby extending the service life of the radiator.

[0053] Further, such as Fig. 9 As shown, the number of the second coolant channels disposed inside the bidirectional folding tooth assembly 31 is three. For ease of understanding, this application uses A to represent the second coolant channel, and Fig. 9 It is marked in that the setting of the first coolant water channel and the second coolant water channel enables the bidirectional folded tooth assembly 31 to distribute heat more evenly, improve the heat dissipation efficiency, and thus effectively reduce the temperature of the server motherboard chip.
