Description

Technical Field

[0001] This utility model relates to the field of server hard drive rack technology, and in particular to a server hard drive rack with liquid cooling. Background Technology

[0002] Server hard drive racks are structural components used to install and secure hard drives. They are typically located at the front of the server chassis and use brackets to neatly arrange multiple hard drives and connect them to the server motherboard or backplane interface, enabling data transfer and power supply between the hard drives and the main system.

[0003] An existing server storage system hard drive heatsink (publication number: CN210983183U) has at least the following drawbacks: Although the above device dissipates heat from the hard drive by moving the fan, traditional air cooling methods have problems such as low heat dissipation efficiency and difficulty in eliminating local hot spots. Especially when the hard drive is continuously read and written, deployed on a large scale, or when edge space is limited, the problem of hard drive overheating becomes more prominent, leading to a decrease in device performance, a decrease in stability, or even hard drive damage. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a server hard drive rack with liquid cooling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A server hard drive rack with liquid cooling includes a bracket. Two partitions are fixed inside the bracket, and support plates are fixed to the top and bottom surfaces of the two partitions. The bracket has a heat dissipation structure for cooling the hard drive. The heat dissipation structure includes two flow cavities formed inside the bracket. Each of the two partitions has two heat dissipation cavities, which are respectively connected to the two flow cavities. A connecting hole is formed between the two heat dissipation cavities. A radiator is located below the bracket, and an inlet pipe and a drain pipe are fixedly connected between the radiator and the two flow cavities.

[0007] As a further embodiment of this utility model, a number of fans are fixed on the bottom surface of the radiator, and a water pump is fixedly connected to one side of the radiator, with the water pump connected and fixedly connected to the water inlet pipe.

[0008] As a further embodiment of this utility model, a number of heat-conducting pads are fixed on the top surface of the partition and the inner bottom surface of the bracket.

[0009] As a further embodiment of this utility model, a plurality of threaded grooves are provided on one side of both the bracket and the support plate.

[0010] As a further embodiment of this utility model, two fixing plates are fixed on both sides of the bracket, and a connection hole is provided on one side of each fixing plate.

[0011] As a further embodiment of this utility model, each of the four corners of the top surface of the radiator is fixed with a pad, and the top of the pad is fixed to the bottom surface of the bracket.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This server hard drive rack, through its heat dissipation structure, uses a water pump to deliver coolant from the radiator through an inlet pipe to the flow chamber and heat dissipation chamber within the rack. The coolant forms a circulation path on the left and right sides through connecting holes, dissipating heat from the top surface of the partition. The heated coolant returns to the radiator through a drain pipe. The radiator is located on the fan exhaust side and provides forced cooling, thereby achieving continuous liquid cooling of the hard drives, effectively improving heat dissipation efficiency, preventing hard drive overheating, and ensuring stable system operation.

[0023] Reference Figures 1-5 A server hard drive rack with liquid cooling includes a bracket 1. Two partitions 2 are fixed inside the bracket 1. Support plates 3 are fixed to the top and bottom surfaces of the two partitions 2. The bracket 1 has a cooling structure for heat dissipation of the hard drive. The cooling structure includes two flow chambers 201 inside the bracket 1. Two heat dissipation chambers 202 are formed inside each of the two partitions 2. The two heat dissipation chambers 202 are respectively connected to the two flow chambers 201. A connecting hole 203 is formed between the two heat dissipation chambers 202. A radiator 204 is located below the bracket 1. An inlet pipe 205 and a drain pipe 206 are fixedly connected between the radiator 204 and the two flow chambers 201. The radiator 204 is existing technology. Coolant is filled inside the radiator 204, the flow chambers 201, the heat dissipation chambers 202, the inlet pipe 205, and the drain pipe 206.

[0024] In this embodiment, several fans 207 are fixed to the bottom surface of the radiator 204, and a water pump 208 is fixedly connected to one side of the radiator 204. The water pump 208 is connected and fixedly connected to the water inlet pipe 205. Through the heat dissipation structure, the user installs and fixes the bracket 1 to the external frame of the server, so that one end of the bracket 1 is precisely connected to the hard drive interface inside the server. Then, the user inserts multiple hard drives into the bracket 1 in sequence and arranges them neatly, so that the hard drive interfaces are connected to the server connection port set in the bracket 1. After the system starts, the fans 207 and the water pump 208 run synchronously. The water pump 208 continuously delivers the coolant in the radiator 204 to the bracket through the water inlet pipe 205. In the flow chamber 201 and heat dissipation chamber 202 on the right side, the coolant flows through the connecting hole 203 in the heat dissipation chamber 202 and enters the flow chamber 201 and heat dissipation chamber 202 on the left side, forming a closed circulation cooling path. This effectively covers and cools the top area of ​​the partition 2. Subsequently, the coolant that has absorbed heat flows back to the radiator 204 through the drain pipe 206. The radiator 204 is located on the exhaust side of the fan 207. When the fan 207 is running, it provides forced cooling, thereby achieving continuous circulation and cooling of the coolant in the hard drive tray. This structure effectively improves the heat dissipation efficiency during hard drive operation, avoids damage to the hard drive due to excessive temperature, and ensures the stability and service life of the equipment.

[0025] In this embodiment, a number of thermal pads 301 are fixed on the top surface of the partition 2 and the inner bottom surface of the bracket 1. The thermal pads 301 are silicone pads with high thermal conductivity, which have good flexibility and compressibility, and can form an effective heat conduction path between the bottom surface of the hard drive and the partition 2, thereby further improving heat dissipation efficiency.

[0026] In this embodiment, both the bracket 1 and the support plate 3 have several threaded grooves 4 on one side. The conventional way to insert a hard drive is to first fix the hard drive to the small bracket, and then insert the small bracket and the hard drive into the bracket 1. After the hard drive is inserted into the bracket 1, the user can fix the small bracket to the bracket 1 with bolts and threaded grooves 4 to ensure the stability of the hard drive after insertion.

[0027] In this embodiment, two fixing plates 5 are fixed on both sides of the bracket 1. Each fixing plate 5 has a connecting hole 501 on one side. The user can use bolts to pass through the connecting hole 501 and use nuts to fix the bracket 1 to the outer frame of the server, thereby completing the installation of the bracket 1.

[0028] In this embodiment, the top four corners of the radiator 204 are fixed with pads 6. The top of the pads 6 is fixed to the bottom of the bracket 1. The pads 6 can reserve air intake space between the radiator 204 and the bracket 1 to ensure the operation of the fan 207.

[0029] Working Principle: During use, the user installs and fixes bracket 1 onto the external frame of the server, ensuring that one end of bracket 1 precisely aligns with the hard drive interface inside the server. Then, the user inserts multiple hard drives into bracket 1 sequentially and arranges them neatly, ensuring the hard drive interfaces align with the server connection ports within bracket 1. After system startup, fan 207 and water pump 208 operate synchronously. Water pump 208 continuously pumps coolant from radiator 204 through inlet pipe 205 to the flow chamber 201 and heat dissipation chamber 202 on the right side of bracket 1. The coolant flows through the connecting hole 203 within heat dissipation chamber 202, entering the flow chamber 201 and heat dissipation chamber 202 on the left side, forming a closed-loop cooling path. This effectively covers and cools the top area of ​​partition 2. Subsequently, the coolant, having absorbed heat,... The coolant flows back to the radiator 204 via the drain pipe 206. The radiator 204 is located on the exhaust side of the fan 207. When the fan 207 is running, it provides forced cooling, thereby achieving continuous circulation and cooling of the coolant in the hard drive tray. The thermal pad 301 is a high thermal conductivity silicone pad with good flexibility and compressibility, which can form an effective heat conduction path between the bottom surface of the hard drive and the partition 2, further improving the heat dissipation efficiency. After the hard drive is inserted into the bracket 1, the user can fix the small bracket to the bracket 1 with bolts and threaded grooves 4 to ensure the stability of the hard drive after insertion. The user can use bolts to pass through the connecting hole 501 to fix the bracket 1 to the server outer frame, thereby completing the installation of the bracket 1. The spacer 6 can reserve air intake space between the radiator 204 and the bracket 1 to ensure the operation of the fan 207.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
