Description

Technical Field

[0001] This utility model relates to the field of server heat dissipation technology, and in particular to a wind-cooled heat dissipation mechanism for a network server. Background Technology

[0002] The physical components of a network server generally include a processor, hard drive, memory, system bus, etc. As a node in the network, the server is closely related to our daily life. For example, we often use mobile phones and laptops to obtain information, communicate with the outside world, and enjoy entertainment. All of these require connection and transmission through the server. When the server is working, it will generate a lot of heat. In order to prevent excessive temperature from causing hardware failure or system crash, the server is equipped with a heat dissipation device.

[0003] Traditional server internal air cooling achieves heat dissipation by directly blowing air onto heat-generating components (such as CPU, GPU, and memory). However, forced airflow carries dust that settles on the circuit board surface, reducing insulation performance and posing a short-circuit risk. Therefore, this solution proposes an air cooling mechanism for network servers that uses a combined air-cooling and liquid-cooling system. The liquid cooling medium acts as a heat conduction intermediary, directing air cooling onto the liquid cooling circuit rather than directly contacting electronic components, thus achieving efficient and low-dust heat dissipation. Utility Model Content

[0004] This invention provides a wind-cooling heat dissipation mechanism for a network server to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A network server air-cooling heat dissipation mechanism includes a server chassis, a server motherboard mounted on the inner side wall of the server chassis, a heat sink fixedly connected to the outer side of the server chassis, multiple vertically penetrating air-cooling channels on the heat sink, an outlet cavity and an inlet cavity respectively opened in the top and top side wall of the heat sink, neither of the outlet cavity nor the inlet cavity is connected to the air-cooling channels, multiple capillary channels are opened in the heat sink, each capillary channel is connected to the outlet cavity and the inlet cavity at both ends respectively, the multiple capillary channels surround the multiple air-cooling channels, and an air intake device is provided on the top of the heat sink; A liquid outlet pipe is fixedly connected to the side wall of the liquid outlet chamber, and one end of the liquid outlet pipe extends into the server chassis. A connecting pipe is fixedly connected to the side wall of the liquid inlet chamber. A liquid pump is provided at the bottom of the server chassis. One end of the connecting pipe extends into the server chassis and communicates with the liquid outlet end of the liquid pump. A suction pipe is fixedly connected to the suction end of the liquid pump.

[0006] The air intake device includes an air guide tube with a circular opening at the top and a rectangular opening at the bottom. The bottom of the air guide tube is fixedly connected to the upper side of the heat sink. The top ends of the multiple air-cooling channels are located inside the bottom opening of the air guide tube. A support plate is fixedly connected to the top of the air guide tube, and a motor is fixedly connected to the bottom side of the support plate. The output shaft of the motor is fixedly connected to a fan blade.

[0007] The heat sink is made of stainless steel.

[0008] Each of the aforementioned air-cooling channels has spiral ribs on its inner sidewall.

[0009] The server chassis is filled with a heat-conducting fluid, which is a fluorinated liquid.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Equivalent to traditional single air-cooling heat dissipation, this device uses air-cooling-liquid-cooling composite heat dissipation, with fluorinated liquid as the heat conduction medium. The air cooling is applied to the liquid cooling circuit of the capillary channel, and the airflow flows in a spiral with the wall, which improves the cooling effect of the fluorinated liquid in the capillary channel and achieves efficient and low-dust heat dissipation.

The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0015] Please see Figures 1 to 7 In this embodiment of the utility model, a network server air-cooling heat dissipation mechanism includes a server chassis 5, a server motherboard 7 installed on the inner side wall of the server chassis 5, and heat-generating components such as CPU, GPU, and memory on the server motherboard 7. The server chassis 5 is filled with a heat-conducting liquid, which is a fluorinated liquid. A heat sink 1 is fixedly connected to the outer side of the server chassis 5. The heat sink 1 is made of high thermal conductivity stainless steel. Multiple vertically penetrating air-cooling channels 15 are opened on the heat sink 1. Spiral protrusions 14 are provided on the inner side wall of each air-cooling channel 15. An outlet cavity 16 and an inlet cavity 11 are respectively opened in the top and top side wall of the heat sink 1. The outlet cavity 16 and the inlet cavity 11 are not connected to the air-cooling channels 15. Multiple capillary channels 13 are opened in the heat sink 1. The two ends of each capillary channel 13 are connected to the outlet cavity 16 and the inlet cavity 11 respectively. The multiple capillary channels 13 surround the multiple air-cooling channels 15. An air intake device is provided on the top of the heat sink 1. A liquid outlet pipe 6 is fixedly connected to the side wall of the liquid outlet chamber 16. One end of the liquid outlet pipe 6 extends into the server chassis 5. A connecting pipe 10 is fixedly connected to the side wall of the liquid inlet chamber 11. A liquid pump 9 is provided at the bottom of the server chassis 5. One end of the connecting pipe 10 extends into the server chassis 5 and communicates with the liquid outlet end of the liquid pump 9. A suction pipe 8 is fixedly connected to the suction end of the liquid pump 9.

[0016] Specifically, the air intake device includes an air duct 2, which has a circular opening at the top and a rectangular opening at the bottom. The bottom of the air duct 2 is fixedly connected to the upper side of the heat sink 1. The tops of multiple air-cooling channels 15 are located inside the bottom opening of the air duct 2. A support plate 4 is fixedly connected to the top of the air duct 2, and a motor 3 is fixedly connected to the bottom side of the support plate 4. A fan blade 12 is fixedly connected to the output shaft of the motor 3. The airflow generated by the motor 3 driving the fan blade 12 will enter the multiple air-cooling channels 15 through the air duct 2. The airflow can cool the fluorinated liquid in the capillary channel 13 through heat exchange in the air-cooling channel 15.

[0017] The working principle of this utility model is as follows: When in use, first start the motor 3 and the liquid pump 9. The liquid pump 9 drives the fluorinated liquid that absorbs heat in the server chassis 5 through the suction pipe 8 and the connecting pipe 10 into the liquid inlet chamber 11. Then, after being cooled by multiple capillary channels 13, it enters the liquid outlet chamber 16 and finally flows back into the server chassis 5 through the liquid outlet pipe 6, so as to achieve continuous heat dissipation inside 5. When the fluorinated liquid passes through the capillary channel 13, the airflow generated by the motor 3 driving the fan blade 12 will enter the multiple air-cooling channels 15. The airflow cools the fluorinated liquid in the capillary channel 13 through heat exchange. At the same time, when the airflow passes through the spiral protrusions 14 on the side wall of the air-cooling channel 15, the spiral protrusions 14 make the airflow spiral when it comes into contact with the wall. The spiral flow can accelerate the heat exchange between the airflow and the wall, and improve the cooling effect of the fluorinated liquid in the capillary channel 13.
