Description

Technical Field

[0001] This utility model relates to the field of computer heat dissipation technology, and more specifically, to a computer backplane circulating liquid cooling interface device. Background Technology

[0002] The basic principle of a liquid cooling system is to use liquid as a heat conduction medium to transfer the heat generated by the heat source to the coolant in the liquid cooling circulation pipe. Then, the coolant carrying heat is circulated through the liquid cooling bellows and the liquid pump to the external water cooling or air cooling system for discharge. The coolant in the liquid cooling radiator is cooled by a chiller or fan, and then it is circulated back to the liquid cooling circulation pipe near the heat source for heat absorption.

[0003] When the liquid cooling circulation pipe is connected to the external liquid cooling bellows, a threaded circulation connection is usually used for fixed connection, and then the internal coolant circulates. However, in order to replace the coolant or repair the cooling components, it is necessary to separate the liquid cooling circulation pipe and the liquid cooling bellows. The two are only connected by threaded engagement. Over time, the threaded structure of the threaded connection between the two will wear, which will make the connection unstable and lead to coolant leakage. The leaked coolant may damage electronic components.

[0004] Therefore, a computer backplane circulating liquid cooling interface device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a computer backplane circulating liquid cooling interface device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a computer backplane circulating liquid cooling interface device, including a back cooling base plate and a liquid cooling circulation pipe. One end of the liquid cooling circulation pipe is fixedly connected to a discharge connector pipe, and the other end of the liquid cooling circulation pipe is connected to an inlet connector pipe. A connecting pipe seat is fixedly provided at one end of both the discharge connector pipe and the inlet connector pipe. A second connecting ring is inserted into each of the two connecting pipe seats. A connector head is fixedly connected to one end of each of the two second connecting rings. A liquid cooling corrugated pipe is connected to the end of each of the two connector heads away from the second connecting rings. A double sealing component is provided on each of the two connecting pipe seats and the two second connecting rings.

[0007] Preferably, the dual sealing assembly includes a sealing rubber gasket, an annular sealing airbag, an air supply pipe, and a micro air pump. A sealing rubber gasket is fixedly disposed on one side of the second connecting ring, and the sealing rubber gasket is located on the outside of the connector. A connecting piece is screwed into one end of the connecting pipe seat. A first connecting ring is fixedly disposed inside the connecting pipe seat. An annular sealing airbag is disposed on the surface of the first connecting ring near the second connecting ring. A micro air pump is installed on the outer wall of the connecting pipe seat, and the output end of the micro air pump is connected to the annular sealing airbag through the air supply pipe.

[0008] Preferably, the connecting piece is located on one side of the sealing rubber gasket, and the surface of the connecting piece away from the sealing rubber gasket is provided with raised textures to increase the friction between the hand and the connecting piece.

[0009] Preferably, the raised texture is made of rubber, and several of the raised textures are evenly distributed in a circular pattern on the surface of the connecting piece.

[0010] Preferably, the liquid cooling circulation pipe is located inside the back cooling substrate, and the discharge connector pipe and discharge connector pipe provided at both ends of the liquid cooling circulation pipe extend out of the side of the back cooling substrate.

[0011] Preferably, a mounting cover is provided on the outer wall of the connecting pipe seat, and the surface of the mounting cover is provided with heat dissipation vents. The mounting cover is placed on the outside of the micro air pump.

[0012] Preferably, the outer side of the connecting piece is provided with an external thread, and the inner side wall of one end of the connecting tube seat is provided with an internal thread that is threadedly connected to the connecting piece.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared to existing technologies, this computer backplane circulating liquid cooling interface device uses a miniature air pump to input gas into an annular sealed airbag, causing the miniature air pump to inflate. The inflated miniature air pump compresses the first and second connecting rings on both sides, improving the sealing performance of the connection between the discharge connector pipe, the inlet connector pipe and the connector, and the liquid cooling bellows, thus preventing leakage of coolant from the liquid cooling circulation pipe and the liquid cooling bellows. At the same time, the compressed first connecting ring causes the connecting pipe seat and the connecting piece to move away from the connector. The moving connecting piece then further compresses the sealing rubber gasket set between the second connecting ring and the connecting piece, thereby further improving the sealing performance of the connection between the discharge connector pipe, the inlet connector pipe and the connector, and the liquid cooling bellows. This structure has a double sealing structure, which can improve the sealing performance of the connection between the liquid cooling circulation pipe and the liquid cooling bellows, thereby preventing leakage of coolant from the liquid cooling circulation pipe and the liquid cooling bellows, which could damage the internal electronic components of the computer.

[0021] Example 1

[0022] As attached Figures 1 to 4 The computer backplane circulating liquid cooling interface device shown includes a back cooling base plate 1 and a liquid cooling circulation pipe 2. One end of the liquid cooling circulation pipe 2 is fixedly connected to a discharge connector pipe 16, and the other end of the liquid cooling circulation pipe 2 is connected to a discharge inlet connector pipe 17. One end of the discharge connector pipe 16 and the discharge inlet connector pipe 17 are both fixedly provided with a connecting pipe seat 3. The liquid cooling circulation pipe 2 is located inside the back cooling base plate 1, and the discharge connector pipe 16 and the discharge inlet connector pipe 17 at both ends of the liquid cooling circulation pipe 2 extend out of the side of the back cooling base plate 1. A second connecting ring 7 is inserted into each of the two connecting pipe seats 3. A connector head 4 is fixedly connected to one end of each of the two second connecting rings 7. A liquid cooling corrugated pipe 5 is connected to the end of each connector head 4 away from the second connecting ring 7. A double sealing assembly is provided on each of the two connecting pipe seats 3 and the two second connecting rings 7.

[0023] Specifically, when using the liquid-cooled bellows 5, the connectors 4 at both ends of the liquid-cooled bellows 5 are connected to the discharge connectors 16 and inlet connectors 17 at both ends of the liquid-cooled circulation pipe 2. First, the second connecting rings 7 at one end of the two connectors 4 are inserted into the connecting pipe seats 3 connected to the discharge connectors 16 and inlet connectors 17. Then, the connecting piece 9 on the outside of the connector 4 is rotated to screw the connecting piece 9 and the connecting pipe seat 3 into a fixed connection. A double sealing component is provided between the two connecting pipe seats 3 and the two second connecting rings 7 respectively, so as to achieve a high sealing connection performance between the liquid-cooled circulation pipe 2 and the liquid-cooled bellows 5, thereby avoiding leakage of coolant in the liquid-cooled circulation pipe 2 and the liquid-cooled bellows 5, which could cause damage to the internal electronic components of the computer.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the dual-sealing assembly includes a sealing rubber gasket 8, an annular sealing airbag 10, an air supply pipe 11, and a miniature air pump 12. A sealing rubber gasket 8 is fixedly disposed on one side of the second connecting ring 7, located outside the connector 4. A connecting piece 9 is screwed onto one end of the connecting tube seat 3, located outside the connector 4, and has an external thread on its outer side. An internal thread, connecting to the connecting piece 9, is provided on the inner wall of one end of the connecting tube seat 3. A first connecting ring 6 is fixedly disposed inside the connecting tube seat 3. An annular sealing airbag 10 is disposed on the surface of the first connecting ring 6 near the second connecting ring 7. A miniature air pump 12 is installed on the outer wall of the connecting tube seat 3, and a mounting cover 14 is provided on the outer wall of the connecting tube seat 3. A heat dissipation vent 15 is provided on the surface of the mounting cover 14, which covers the miniature air pump 12. The output end of the miniature air pump 12 is connected to the annular sealing airbag 10 via the air supply pipe 11, and the air pump 12 supplies air to the annular sealing airbag 10. Gas is input into the sealed airbag 10, causing the micro air pump 12 to inflate. The inflated micro air pump 12 compresses the first connecting ring 6 and the second connecting ring 7 on both sides, improving the sealing performance of the connection between the discharge connector pipe 16, the inlet connector pipe 17 and the connector 4 and the liquid-cooled bellows pipe 5, thus preventing leakage of coolant in the liquid-cooled circulation pipe 2 and the liquid-cooled bellows pipe 5. At the same time, the compressed first connecting ring 6 drives the connecting pipe seat 3 and the connecting piece 9 to move away from the connector 4. The moving connecting piece 9 further compresses the sealing rubber gasket 8 set between the second connecting ring 7 and the connecting piece 9, thereby further improving the sealing performance of the connection between the discharge connector pipe 16, the inlet connector pipe 17 and the connector 4 and the liquid-cooled bellows pipe 5. This structure has a double sealing structure, which can improve the sealing performance of the connection between the liquid-cooled circulation pipe 2 and the liquid-cooled bellows pipe 5, thereby preventing leakage of coolant in the liquid-cooled circulation pipe 2 and the liquid-cooled bellows pipe 5, which could cause damage to the internal electronic components of the computer.

[0027] In a preferred embodiment, the connecting piece 9 is located on the side of the sealing rubber gasket 8, and a raised texture 13 is provided on the surface of the connecting piece 9 away from the sealing rubber gasket 8 to increase the friction between the hand and the connecting piece 9. The raised texture 13 is made of rubber material, and several raised textures 13 are evenly distributed in a circle on the surface of the connecting piece 9. The setting of the raised texture 13 makes it convenient to rotate the connecting piece 9 through the position of the raised texture 13, so that the connecting piece 9 can be screwed into the connecting tube seat 3.

[0028] In this embodiment, the miniature air pump 12 is a commercially available device known to those skilled in the art. It can be customized or a specific model can be selected according to actual needs. Here, we are simply using it without making any structural or functional improvements, and we will not go into detail about it here.

[0029] The working process of this utility model is as follows: First, the second connecting ring 7 at one end of the two connectors 4 can be inserted into the connecting pipe seat 3 connected to one end of the discharge connector pipe 16 and the inlet connector pipe 17. Then, the connecting piece 9 on the outside of the connector 4 is rotated to screw the connecting piece 9 and the connecting pipe seat 3 into a fixed connection. Next, gas is input into the annular sealing airbag 10 through the micro air pump 12, which causes the micro air pump 12 to inflate. The inflated micro air pump 12 will squeeze the first connecting ring 6 and the second connecting ring 7 on both sides, improving the sealing performance of the connection between the discharge connector pipe 16, the inlet connector pipe 17 and the connector 4 and the liquid-cooled bellows 5, and preventing the leakage of coolant in the liquid-cooled circulation pipe 2 and the liquid-cooled bellows 5. Simultaneously, the squeezed first connecting ring 6 will cause the connecting tube seat 3 and connecting piece 9 to move away from the connector 4. Then, the moving connecting piece 9 will further squeeze the sealing rubber gasket 8 set between the second connecting ring 7 and the connecting piece 9, thereby further improving the sealing performance of the connection between the discharge connector pipe 16, the inlet connector pipe 17 and the connector 4, and the liquid cooling bellows 5. This structure has a double sealing structure, which can improve the sealing performance of the connection between the liquid cooling circulation pipe 2 and the liquid cooling bellows 5, thereby avoiding the leakage of coolant in the liquid cooling circulation pipe 2 and the liquid cooling bellows 5, which could cause damage to the internal electronic components of the computer. The above is the working principle of this computer backplane circulating liquid cooling interface device.
