[0002] With the rapid development of information technology, data centers are the core of information storage, processing and transmission. Their operating efficiency and stability are crucial to the normal operation of modern society. The server motherboard chip in the data center is one of the key components for the efficient operation of the data center. However, due to its high degree of integration and high power consumption, the heat dissipation problem of chip heat generating components has become a bottleneck restricting the improvement of server performance.

[0003] Traditional server radiators usually use a shovel-tooth water channel structure. Although this structure can achieve heat dissipation to a certain extent, it has problems such as large water resistance of the internal teeth of the radiator, low heat dissipation efficiency of the heat dissipation teeth, large overall pressure drop, high temperature and short service life. Specifically, the large water resistance leads to a decrease in water flow speed, thereby reducing the efficiency of heat exchange; the low heat dissipation efficiency of the heat dissipation teeth means that the heat dissipation performance of the radiator is not fully utilized; the large overall pressure drop requires the water pump to consume more energy to maintain the stable operation of the system; and excessive temperature directly affects the performance and stability of the server; finally, due to high temperature and large pressure drop, the service life of the radiator will be shortened accordingly. Therefore, we make improvements to this and propose a two-way folded tooth water channel structure for liquid-cooled servers. Summary of the invention

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0034] As recorded in the background technology, traditional server radiators usually adopt a shovel-tooth water channel structure. Although this structure can achieve heat dissipation to a certain extent, it has problems such as large water resistance of the internal teeth of the radiator, low heat dissipation efficiency of the heat dissipation teeth, large overall pressure drop, high temperature and short service life. Specifically, the large water resistance leads to a decrease in water flow velocity, thereby reducing the efficiency of heat exchange; the low heat dissipation efficiency of the heat dissipation teeth means that the heat dissipation performance of the radiator is not fully utilized; the large overall pressure drop requires the water pump to consume more energy to maintain the stable operation of the system; and excessive temperature directly affects the performance and stability of the server; finally, due to the high temperature and large pressure drop, the service life of the radiator will be shortened accordingly.

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

[0036] Specifically, please refer to Figure 1-Figure 9 The bidirectional folded tooth water channel structure of the liquid cooling server specifically includes:

[0037] A base 1 and a protective cover 2 installed on the top of the base 1. The top of the base 1 is also provided with a bidirectional folded tooth water channel component 3 located inside the protective cover 2. The bidirectional folded tooth water channel component 3 includes a plurality of bidirectional folded tooth assemblies 31 arranged side by side and fixedly installed on the top of the base 1. A plurality of first coolant water channels are arranged between the plurality of bidirectional folded tooth assemblies 31, and a plurality of second coolant water channels are arranged inside each bidirectional folded tooth assembly 31.

[0038] The bidirectional folded tooth water channel structure of the liquid-cooled server provided by the utility model has a bidirectional folded tooth component 31, and a plurality of first coolant water channels are arranged between a plurality of bidirectional folded tooth components 31, and a plurality of second coolant water channels are arranged inside each bidirectional folded tooth component 31, so that the structure of the bidirectional folded tooth water channel component 3 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, thereby effectively reducing 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 reducing the burden on the radiator by reducing the temperature and pressure drop, thereby extending the service life of the radiator.

[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 9 The bidirectional folded tooth water channel structure of the liquid-cooled server includes a base 1 and a protective cover 2 installed on the top of the base 1. The top of the base 1 is also provided with a bidirectional folded tooth water channel component 3 located in the protective cover 2. The bidirectional folded tooth water channel component 3 includes a plurality of bidirectional folded tooth assemblies 31 arranged side by side and fixedly installed on the top of the base 1. A plurality of first coolant water channels are arranged between the plurality of bidirectional folded tooth assemblies 31. A plurality of second coolant water channels are arranged inside each bidirectional folded tooth assembly 31. 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. The structure 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 enable the bidirectional folded tooth assembly 31 to distribute heat more evenly, improve the heat dissipation efficiency, and effectively reduce the temperature of the server motherboard chip; due to the reduction of water flow resistance, the overall pressure drop is also reduced, which improves the operating efficiency of the system, reduces the burden of the radiator by reducing the temperature and pressure drop, thereby extending the service life of the radiator, and the first coolant water channel and the second coolant water channel are interconnected, so that the overall contact area with the coolant is greatly increased;

[0043] The provision of the first coolant water channel and the second coolant water channel makes the present application lighter and reduces the cost.

[0044] Further, such as Figure 7-Figure 9 As shown, the bidirectional folding tooth assembly 31 includes a plurality of folding tooth bodies 311, which are connected end to end and staggered with each other. 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.

[0045] 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.

[0046] Further, such as Figure 7-Figure 9 As shown, the bidirectional folding tooth assembly 31 also includes two connecting plates 312 , and the two sides of the bottom of the folding tooth body 311 are fixedly connected to the two connecting plates 312 respectively. The setting of the connecting plates 312 can improve the stability of the connection between the folding tooth bodies 311 .

[0047] Further, such as Figure 4 As shown, the connecting plate 312 between two adjacent bidirectional folded tooth assemblies 31 is fixedly connected to improve the overall firmness and integrity, and the bottom of the connecting plate 312 is fixedly connected to the top of the base 1, so as to facilitate heat exchange with components that need heat dissipation through the base 1.

[0048] Example 2 further optimizes the bidirectional folded tooth water channel structure of the liquid cooling server provided in Example 1. Specifically, Figure 1-Figure 2 As shown, a sealing groove 101 is provided at the top of the base 1 , and the bottom of the protective cover 2 is inserted into the sealing groove 101 . The provision of the sealing groove 101 can improve the sealing performance of the connection between the protective cover 2 and the base 1 .

[0049] Further, such as Figure 2As shown, a liquid inlet 201 is provided on one side of the top of the protective cover 2, and a liquid inlet chamber 203 is provided between the liquid inlet 201, the base 1 and the bidirectional folded tooth water channel component 3. The liquid inlet chamber 203 increases the liquid inlet area of ​​the coolant, which can effectively reduce the flow resistance of the coolant between the base 1 and the protective cover 2, increase the flow speed of the coolant, thereby enhancing the heat dissipation effect and achieving an overall pressure drop.

[0050] Further, such as Figure 2 As shown, a liquid outlet 202 is provided on the other side of the top of the protective cover 2, and a liquid outlet chamber 204 is provided between the liquid outlet 202, the base 1 and the bidirectional folded tooth water channel component 3. The liquid outlet chamber 204 increases the area of ​​the coolant outlet, which can effectively reduce the flow resistance of the coolant between the base 1 and the protective cover 2, increase the flow speed of the coolant, thereby enhancing the heat dissipation effect and achieving an overall pressure drop.

[0051] Example 3 further optimizes the bidirectional folded tooth water channel structure of the liquid cooling server provided in Example 1 or 2. Specifically, Figure 1 As shown, a plurality of mounting holes 102 are provided on the base 1 , and the mounting holes 102 are used for mounting the base 1 , that is, the base 1 can be fixed at a corresponding position by passing bolts through the mounting holes 102 .

[0052] Further, such as Figure 1 As shown, a fool-proof slope 103 is provided at a corner of the base 1 .

[0053] The use process of the bidirectional folded tooth water channel structure of the liquid cooling server provided by the utility model is as follows:

[0054] The coolant enters the liquid inlet chamber 203 from the liquid inlet 201 , then passes through the first coolant water channel and the second coolant water channel and contacts the folding tooth body 311 and the base 1 to achieve heat exchange, and then the coolant reaches the liquid outlet chamber 204 and is discharged from the liquid outlet 202 .
