Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a water-cooled heat dissipation plate for a server. Background Art

[0002] A water-cooled radiator refers to a radiator that uses a liquid to be forced to circulate under the drive of a pump to take away the heat of a computer CPU. This radiator has the advantages of being quiet, having stable temperature reduction, and being less dependent on the environment, and is widely used in computer accessories.

[0003] Existing water-cooled radiators usually include a water-cooled radiator and a water-cooled head. The water-cooled radiator and the water-cooled head are connected by a water-cooled pipe. The water-cooled pipe includes an inlet pipe and an outlet pipe. The inlet pipe introduces low-temperature liquid from the water-cooled radiator into the water-cooled head. After passing through the water-cooled head, the low-temperature liquid increases in temperature and becomes high-temperature liquid, which then flows back into the water-cooled radiator through the outlet pipe for cooling. Such a cycle is used to quickly dissipate the heat of the CPU.

[0004] Among them, the utility model with the application number 202322065757.6 discloses a side-access water-cooled radiator, which includes a first water tank and a second water tank arranged opposite to each other, and a plurality of heat dissipation pipes arranged between the first water tank and the second water tank. A liquid flow channel is arranged on one side between the first water tank and the second water tank. The two ends of the liquid flow channel are respectively communicated with the first water tank and the second water tank. An inlet and an outlet are arranged at the liquid flow channel. A baffle is arranged between the inlet and the outlet to realize the one-way circulating flow of the liquid in the water-cooled radiator; by arranging a liquid flow channel on one side of the first water tank and the second water tank, and at the same time arranging an inlet and an outlet at the liquid flow channel, it is convenient to arrange the inlet and the outlet at the long side of the water-cooled radiator, so that the travel for installing the inlet pipe and the outlet pipe of the water-cooled radiator is shortened, thereby improving the aesthetics after the installation of the water-cooled radiator and reducing the blockage of the water-cooled pipe to the air duct in the chassis.

[0005] The existing water-cooled plate is composed of an upper plate and a lower plate. The lower plate is formed with a water-cooled flow channel. When the upper plate and the lower plate are welded, it is a flat welding. After flat welding, its sealing performance is relatively general. The water-cooled liquid in the water-cooled flow channel is easy to overflow from the gap, resulting in a liquid leakage phenomenon, which affects the use effect. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a water-cooled heat dissipation plate for a server in view of the deficiencies of the prior art.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

The welded plate is formed with a water-cooled flow channel for the circulation of water-cooled liquid. The water-cooled flow channel includes a flow channel and a water storage cavity. A first sealing protrusion with a first height for welding is formed on the periphery of the water-cooled flow channel. A second sealing protrusion with a second height for welding is formed on the periphery of the first sealing protrusion. The first height is less than the second height. The welded cover plate is provided with a shovel tooth structure coaxially aligned with the water storage cavity. The shovel tooth structure protrudes from the bottom surface of the welded cover plate. After the welded plate and the welded cover plate are welded, the shovel tooth structure is located in the water storage cavity.

[0009] Further: The flow channel includes a first flow channel for the water-cooled liquid to enter the water storage cavity and a second flow channel for the water-cooled liquid to discharge out of the water storage cavity. Both the first flow channel and the second flow channel are communicated with the water storage cavity.

[0010] Further: The shovel tooth structure includes a plurality of shovel tooth plates arranged parallel to each other at intervals. The shovel tooth plates are arranged along the width direction of the water storage cavity. The length of the shovel tooth plate is less than the width of the water storage cavity.

[0011] Further: There is a front gap for the water-cooled liquid to flow between the shovel tooth plate and the rear wall of the water storage cavity, and there is a rear gap for the water-cooled liquid to flow between the shovel tooth plate and the front wall of the water storage cavity. The front gap is communicated with the first flow channel, and the rear gap is communicated with the second flow channel.

[0012] Further: The distance between two adjacent shovel tooth plates is the same.

[0013] Further: One end of the welded plate and the welded cover plate is connected with a joint seat. There are a first joint hole and a second joint hole at the bottom of the joint seat.

[0016] Further: The welded plate is formed with a plurality of bottom connection holes, and the welded cover plate is formed with a plurality of top connection holes coaxially matched with the bottom connection holes.

[0017] The beneficial effects of the present utility model: When the welded plate and the welded cover plate are brazed, the first sealing protrusion of the welded plate is integrally formed and connected with the welded cover plate, which can seal and separate the water-cooled flow channel to prevent the leakage of water-cooled liquid. At the same time, the second sealing protrusion formed on the periphery of the first sealing protrusion is integrally formed and connected with the welded cover plate, which can further seal and separate the water-cooled flow channel, and further reduce the probability of water-cooled liquid leakage.

[0031] The present utility model will be described in detail below with reference to the accompanying drawings.

[0032] As Figures 1-3 shown, a server water-cooled heat dissipation plate includes a water-cooled plate 1. The water-cooled plate 1 includes a welding plate 11 and a welding cover plate 12 which are brazed and welded. The welding plate 11 is formed with a plurality of bottom connection holes 14, and the welding cover plate 12 is formed with a plurality of top connection holes 13 that are coaxially matched with the bottom connection holes 14. After welding, the welding plate 11 and the welding cover plate 12 are connected through the bottom connection holes 14 and the top connection holes 13 to ensure the stability of the connection.

[0033] The welding plate 11 is formed with a water-cooling flow channel 3 for the water-cooling liquid to flow through. The water-cooling flow channel 3 includes a flow channel and a water storage cavity 31. The periphery of the water-cooling flow channel 3 is formed with a first sealing protrusion 34 with a first height for welding, and the periphery of the first sealing protrusion 34 is formed with a second sealing protrusion 35 with a second height for welding. The first height is less than the second height;

[0034] When the welding plate 11 and the welding cover plate 12 are brazed, the first sealing protrusion 34 of the welding plate 11 is integrally formed and connected with the welding cover plate 12, which can seal and separate the water-cooling channel 3 to prevent the leakage of the water-cooling liquid. At the same time, the second sealing protrusion 35 formed around the first sealing protrusion 34 is integrally formed and connected with the welding cover plate 12, which can further seal and separate the water-cooling channel 3, ensuring the flatness of the welding while further reducing the probability of water-cooling liquid leakage.

[0035] The welding cover plate 12 is provided with a shovel tooth structure coaxially aligned with the water storage cavity 31. The shovel tooth structure protrudes and is formed on the bottom surface of the welding cover plate 12. After the welding plate 11 and the welding cover plate 12 are welded, the shovel tooth structure is located in the water storage cavity 31. After the water-cooling liquid passes through the cold storage cavity, it can contact the shovel tooth structure to dissipate heat from the welding cover plate 12, increasing the contact area and further improving the heat dissipation effect of the welding cover plate 12.

[0036] The flow channel includes a first flow channel 32 for the water-cooling liquid to enter the water storage cavity 31 and a second flow channel 33 for the water-cooling liquid to discharge outward from the water storage cavity 31. Both the first flow channel 32 and the second flow channel 33 are communicated with the water storage cavity 31. The water-cooling liquid enters the water storage cavity 31 through the first flow channel 32 and then flows out through the second flow channel 33 to dissipate heat from the shovel tooth structure in the water storage cavity 31.

[0037] Specifically, the shovel tooth structure includes a plurality of shovel tooth plates 36 arranged parallel to each other at intervals. The shovel tooth plates 36 are arranged along the width direction of the water storage cavity 31. The length of the shovel tooth plates 36 is less than the width of the water storage cavity 31. The shovel tooth plates 36 can contact the water-cooling liquid surface, and the contact area between the water-cooling liquid and the shovel tooth structure is relatively large, which can dissipate the heat accumulated on the welding cover plate 12.

[0038] Further, there is a front gap 37 for the water-cooling liquid to flow between the shovel tooth plate 36 and the rear wall of the water storage cavity 31, and there is a rear gap for the water-cooling liquid to flow between the shovel tooth plate 36 and the front wall of the water storage cavity 31. The front gap 37 is communicated with the first flow channel 32, and the rear gap is communicated with the second flow channel 33. The water-cooling liquid enters the front gap 37 through the first flow channel 32, passes through the gaps between the plurality of shovel tooth plates 36 to fully contact the shovel tooth structure, and after entering the rear gap, converges into the second flow channel 33 and is discharged.

[0039] Preferably, the distance between two adjacent shovel tooth plates 36 is the same.

[0040] One end of the welding plate 11 and the welding cover plate 12 is connected with a joint seat 2. There are a first joint hole 21 and a second joint hole 22 at the bottom of the joint seat 2. The bottom of the joint seat 2 is welded to the welding cover plate 12. The welding cover plate 12 is formed with a water-cooling inlet 15 communicating with the first flow channel 32 and a water-cooling outlet 16 communicating with the second flow channel 33. The water-cooling liquid can enter the first flow channel 32 through the first joint hole 21 of the joint seat 2 and into the water-cooling inlet 15 of the welding cover plate 12. Conversely, the water-cooling liquid flowing through the second flow channel 33 is discharged to the second joint hole 22 of the joint seat 2 through the water-cooling outlet 16.

[0041] A first joint cavity 23 communicating with the first joint hole 21 and a second joint cavity 24 communicating with the second joint hole 22 are longitudinally formed in the joint seat 2. A pair of top holes 25 are formed at the top of the joint seat 2, and a pair of side holes 26 are formed at the side of the joint seat 2. According to requirements, the pipeline can be connected to the top holes 25 or the side holes 26 of the joint seat 2 to realize the inflow and outflow of the water-cooling liquid.

[0042] In summary, it can be seen that the present utility model has the excellent characteristics described above, so that it can enhance the efficiency that has never been seen in the prior art during use and has practicability, becoming a product with extremely high practical value.

[0043] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
