Technical Field

[0001] The utility model belongs to the technical field of server liquid cooling, in particular to a server hard disk liquid cooling structure. Background Art

[0002] The server has high-speed CPU computing power, long-term reliable operation, strong I / O external data throughput capacity and better scalability. According to the services provided by the server, generally speaking, the server has the ability to respond to service requests, provide services, and guarantee services. The server is an important data processing hardware product, which has important application support in the fields of AI intelligence, big data processing, edge computing, etc. Its manufacturing process is complex and the quality control is strict.

[0003] The heat dissipation methods of server internal components are generally divided into two categories: air cooling and liquid cooling. As the power consumption of server internal components gradually increases, air cooling is increasingly unable to meet the server heat dissipation needs, and liquid cooling is increasingly being used.

[0004] At present, the most widely used is indirect liquid cooling, that is, cold plate liquid cooling. There are not only CPU cold plate liquid cooling and DIMM cold plate liquid cooling, but also hard disk cold plate liquid cooling. The traditional hard disk heat dissipation method is air cooling. As the power consumption of the hard disk increases, the required fan speed is also getting higher and higher. The problem that comes with it is that the aerodynamic noise causes the hard disk read and write rate to decrease or even drop the disk. Therefore, how to solve the problems of high PUE of the hard disk air cooling method and the continuous increase of fan speed leading to the decrease of hard disk read and write rate are technical problems that technical personnel in this field need to solve urgently. Utility Model Content

[0005] In order to solve the problem that the hard disk reading and writing rate decreases due to the high PUE of the hard disk air cooling heat dissipation method and the continuous increase of the fan speed, the utility model provides a server hard disk liquid cooling structure.

[0008] A further improvement of the utility model is that a first heat-conducting pad is provided between the stopper and the water collector.

[0009] A further improvement of the utility model is that a limiting protrusion capable of positioning and installing the first thermal pad is provided on a side of the stop portion close to the water collector.

[0010] A further improvement of the utility model is that a second heat conductive pad is provided on a side of the hard disk cold plate close to the hard disk.

[0011] A further improvement of the utility model is that a clamping portion capable of clamping and limiting the hard disk is provided on a side of the stop portion away from the hard disk cold plate.

[0012] A further improvement of the utility model is that one end of the engaging portion close to the water collector is chamfered.

[0013] A further improvement of the utility model is that one end of the hard disk cold plate away from the stop portion is connected and installed with the hard disk through a first screw.

[0014] A further improvement of the present invention is that a hard disk bracket capable of being locked and installed with a chassis is connected to one end of the hard disk away from the water collector; the hard disk bracket is connected and installed with the hard disk via the first screw.

[0015] A further improvement of the utility model is that the hard disk cold plate includes a first cold plate and a second cold plate; a groove for engaging with the second cold plate is provided on the inner side of one end of the first cold plate close to the water collector; the stopper is integrally arranged with the second cold plate; the first cold plate is made of aluminum plate, and the second cold plate is made of copper plate.

[0029] The server hard disk liquid cooling structure is suitable for the E1.S hard disk in the 1U server. The hard disk cold plate 5 is fixedly connected to the hard disk 4. The heat of the hard disk 4 is conducted through the hard disk cold plate 5, and the heat transfer is strengthened through the heat pipe 57. The heat is transferred to the water collector 3 through the stopper 54. The circulating water in the water collector 3 (water inlet pipe 31, water outlet pipe 32) takes away the heat, thereby realizing efficient heat dissipation of the hard disk 4, reducing the PUE value, reducing noise, and avoiding the problem of reduced read and write rate of the hard disk 4. The hard disk cold plate 5 is small in size and is independently set from the water collector 3, which is convenient for maintenance of the liquid cooling module; there is no water in the hard disk cold plate 5, the flow resistance of the entire module is reduced, and the risk of liquid leakage is small; and the number of hard disk cold plates 5 can be flexibly configured according to the shipment volume of the hard disk 4, effectively realizing cost reduction. The overall structure is simple, easy to implement, and practical.

[0031] like Figure 4-6 As shown, a first heat conductive pad 53 is provided between the stopper 54 and the water collector 3. The first heat conductive pad 53 is used to achieve close fit with the water collector 3 and efficient heat conduction, and the first heat conductive pad 53 has a certain amount of compression. After the hard disk 4 and the hard disk connector on the hard disk backplane 2 are plugged in place, the first heat conductive pad 53 can be compressed by 0.4 mm to ensure reliable contact fit.

[0032] Among them, Figure 6 As shown, a stopper 54 is provided on one side (rear side) of the water collector 3 with a limiting protrusion 58 capable of positioning and installing the first thermal pad 53. The first thermal pad 53 is effectively and precisely positioned by four limiting protrusions 58, thereby ensuring the accuracy and reliability of the installation of the first thermal pad 53.

[0033] Furthermore, in order to ensure efficient heat transfer between the hard disk 4 and the hard disk cold plate 5 , a second heat conductive pad is provided on a side of the hard disk cold plate 5 close to the hard disk 4 .

One end of the hard disk cold plate 5 away from the stopper 54 is connected and installed with the hard disk 4 through a first screw 7. The clamping portion 55 and the stopper 54 can effectively clamp and limit the rear of the hard disk 4, and the hard disk cold plate 5 is connected and installed with the front of the hard disk 4 through the first screw 7, thereby ensuring the reliability of the connection between the hard disk 4 and the hard disk cold plate 5.

[0035] In order to ensure smooth installation of the hard disk cold plate 5 and the hard disk 4 into the chassis 1 , one end of the engaging portion 55 close to the water collector 3 is chamfered to play a guiding role.

[0036] Among them, Figure 4 As shown, the hard disk 4 is connected to one end away from the water collector 3 with a hard disk bracket 6 that can be locked and installed with the chassis 1; the hard disk bracket 6 is connected and installed with the hard disk 4 through the first screw 7. The hard disk bracket 6 can achieve reliable engagement with the chassis 1, ensuring the reliability of the connection between the hard disk 4 and the hard disk connector on the hard disk backplane 2. And the two first screws 7 can realize the convenient and reliable connection and installation of the hard disk cold plate 5, the hard disk 4 and the hard disk bracket 6.

[0037] Among them, Figure 5-6 As shown, the hard disk cold plate 5 includes a first cold plate 51 and a second cold plate 52; a notch for engaging with the second cold plate 52 is provided on the inner side of one end (rear end) of the first cold plate 51 close to the water collector 3; the stopper 54 and the clamping part 55 are integrally arranged with the second cold plate 52; the first cold plate 51 is made of an aluminum plate, and the second cold plate 52 is made of a copper plate. The copper plate has a higher thermal conductivity than the aluminum plate, and is heavier than the aluminum plate, which effectively ensures efficient heat transfer and achieves lightweight.

[0038] Among them, Figure 6 As shown, the first cold plate 51 and the second cold plate 52 are fixedly connected by welding and the second screw 8. The reliability of the connection between the first cold plate 51 and the second cold plate 52 is achieved.

[0039] In the server hard disk liquid cooling structure, the hard disk cold plate 5 is fixedly connected with the hard disk 4. The heat of the hard disk 4 is conducted through the hard disk cold plate 5, and the heat is transferred to the water collector 3 through the stopper 54. The heat is taken away by the circulating water in the water collector 3 (water inlet pipe 31, water outlet pipe 32), thereby realizing efficient heat dissipation of the hard disk 4, reducing the PUE value, reducing noise, and avoiding the problem of reduced read and write rate of the hard disk 4. The hard disk cold plate 5 is small in size and is independently set from the water collector 3, which is convenient for maintenance of the liquid cooling module; there is no water in the hard disk cold plate 5, the flow resistance of the entire module is reduced, and the risk of leakage is small; and the number of hard disk cold plates 5 can be flexibly configured according to the shipment volume of the hard disk 4, effectively realizing cost reduction.
