Description

Technical Field

[0001] The invention relates to the technical field of server heat dissipation, and in particular to a liquid cooling heat dissipation device for a server chassis. Background Art

[0002] A server is a specific IT device that provides computing power and runs software applications in a network environment. It provides computing or application services to other clients (such as personal computers, smart phones, ATM machines and other terminal devices) in the network. Generally speaking, servers have the ability to respond to service requests, provide services, and ensure services.

[0003] When processing large amounts of data, the internal components of the server, such as the CPU, GPU, and memory, consume electricity and convert it into heat energy, causing the server to generate a lot of heat. To address the problem of large amounts of heat generated by server operation, common auxiliary server heat dissipation methods on the market generally include air cooling and liquid cooling. Liquid cooling uses a pump to make the coolant in the heat pipe flow through the heat source of the server, absorbing and taking away the heat from the server heat source, thereby achieving the purpose of lowering the server temperature. However, the liquid cooling system of most servers on the market has its heat pipes installed inside the server chassis. When the server is running, the overall temperature inside the chassis will rise, causing the coolant in the heat pipe to absorb the temperature inside the chassis in advance before flowing through the heat source of the server, thereby reducing the heat absorption of the server heat source by the coolant, which needs to be improved.

The upper ends of the lifting rod 18 and the telescopic rod 19 are fixedly connected with a ring 20, and the ring 20 is movably sleeved on the outer side of the positioning shaft 17.

[0026] Working principle: When the server of the chassis body 1 is running, the heat sink 3 attached to the server heat source absorbs the heat of the server heat source, and the water pump 5 drives the cold water to circulate in the water cooling tube 4. When the circulating cold water flows to the connection part between the water cooling tube 4 and the heat sink 3, the cold water absorbs the heat of the heat sink 3 and takes the heat away, assisting the heat dissipation of the server heat source. Since the water cooling tube 4 is located outside the chassis body 1, it will not be affected by the internal temperature of the chassis body 1, and can effectively prevent the cold water from absorbing heat in advance when flowing through the heat sink 3, effectively improving the efficiency of cold water-assisted server heat dissipation; After the cold water flows into the radiator 6 , the multiple fans 8 are operated to blow air to the radiator 6 , which can quickly reduce the water temperature in the radiator 6 .

[0027] Example 2: Please refer to Figure 3 , Figure 5 , Figure 6 This embodiment further explains Example 1, the liquid filling component includes a flexible conduit 21 fixedly installed at the lower end of the hollow box 9 and interconnected therewith, a sleeve 22 is installed on the outer side of one end of the flexible conduit 21 away from the hollow box 9, and the sleeve 22 is fixedly installed on the outer side of the chassis body 1 through a positioning seat, a flexible conduit 23 is installed on the lower side of the sleeve 22, a one-way valve 24 is fixedly installed between the flexible conduit 21 and the flexible conduit 23 and the sleeve 22, and the end of the flexible conduit 23 away from the sleeve 22 is fixedly connected to a liquid storage tank 25, and the liquid storage tank 25 is used to store low-concentration alcohol.

[0028] A top cover 26 is threadedly mounted on the upper end of the sleeve 22, a piston 27 is movably embedded inside the sleeve 22, a pressure rod 28 is fixedly embedded at the center of the upper end of the piston 27, and the pressure rod 28 passes through the top cover 26, an anti-slip groove is provided on the outer side of the top cover 26, a pressure block 29 is fixedly connected to the upper end of the pressure rod 28, a spring 30 is movably sleeved on the outer side of the pressure rod 28, and both ends of the spring 30 are movably abutted against the top cover 26 and the pressure block 29 respectively, and the upper end surface of the pressure block 29 is movably abutted against the pressure plate 16.

[0029] In this embodiment: during the operation of the server, personnel can control the operation of the lifting rod 18, and the operation of the lifting rod 18 drives the hollow box 9 and the tampon 11 to move downward. When the pressure plate 16 on the hollow box 9 moves downward to resist the pressure block 29 and continues to move downward, the pressure plate 16 will drive the piston 27 to move downward inside the sleeve 22 through the pressure block 29. During this process, the low-concentration alcohol inside the sleeve 22 will be squeezed into the hollow box 9 through the flexible conduit 1 21. Since the interior of the hollow box 9 is full of liquid, the quantitative low-concentration alcohol in the hollow box 9 will flush open the rubber valve 15 in the embedded tube 14, and then enter the tampon 11 through the through hole on the fixed plate 10. After the quantitative low-concentration alcohol inside the hollow box 9 is squeezed out, the rubber valve 15 in the embedded tube 14 will close under its own elastic performance; After the low-concentration alcohol enters the tampon 11, it will wet the tampon 11. In the process of the lifting rod 18 driving the tampon 11 to move upward, the low-concentration liquid alcohol can be applied to the surface of the heat sink 3 and the water-cooling tube 4. The heat dissipation effect of the water cooling mechanism can be further improved through the evaporation and heat absorption performance of the low-concentration alcohol.

[0033] In this embodiment: when the lifting rod 18 drives the sliver 11 to move upward and away from the heat sink 3, and moves to the connecting plate 32 and continues to move upward, since the gear 31 is meshed and connected with the connecting plate 32 through a plurality of tooth blocks 33, the connecting plate 32 can drive the gear 31 and the hollow box 9 to rotate 90° clockwise through the tooth block 33 during the upward movement of the gear 31, so that the sliver 11 rotates to the upper side of the hollow box 9. Under the condition that the fixed plate 10 and the sliver 11 are plugged and unplugged with the hollow box 9, personnel can easily disassemble and replace the sliver 11 to avoid excessive accumulation of dust on the sliver 11. When the lifting rod 18 drives the hollow box 9 to move downward, the connecting plate 32 will drive the gear 31 to rotate and reset through a plurality of tooth blocks 33; During the rotation of the gear 31 and the positioning shaft 17, the hemispherical part of the pin 34 will be embedded in the corresponding hemispherical slot 36 under the drive of the spring 2 35, so as to position the positioning shaft 17 and the hollow box 9, and prevent the hollow box 9 from rotating during the process of disassembling and assembling the cotton strip 11 or wiping the heat sink 3 with the cotton strip 11.
