Description

Technical Field

[0001] The utility model belongs to the field of server heat dissipation, in particular to a server heat dissipation structure. Background Art

[0002] The heat dissipation principle of the server can be simply summarized as: transferring the heat generated inside the server to the external environment. The heat inside the server mainly comes from the work of components such as the processor, memory, and hard disk. These components will generate a lot of heat when working. If the heat is not dissipated in time, the server temperature will rise, thereby affecting the performance and life of the server.

[0003] In order to solve the problem of server heat dissipation, existing servers usually use fan cooling and liquid cooling;

[0004] Fan cooling: Multiple fans are usually installed inside the server, which achieve heat dissipation by sucking in external air and exhausting hot air outside the server;

[0005] Liquid cooling: By circulating the coolant, heat is transferred from the inside of the server to the external environment. Liquid cooling usually requires the installation of water pumps, radiators and other equipment, so the cost is relatively high.

[0006] During the fan cooling process, when the fan draws air into the server, the air will first be filtered through the filter of the server's air inlet duct. As the fan cooling time increases, dust on the outside of the server's air inlet duct filter will gradually accumulate. If the staff does not clean it in time, the fan cooling air intake will be insufficient, which will affect the server's cooling effect. Utility Model Content

[0033] The utility model is further described below in conjunction with the accompanying drawings.

[0034] like Figure 1 and 5 As shown, the utility model provides a server heat dissipation structure, including:

[0035] The shell 2 has a left air guide channel 5 and a right air guide channel 7 on both sides of the inner wall of the shell 2, and a left air guide hole 6 and a right air guide hole 3 on both sides of the outer wall of the shell 2 near the bottom thereof, the left air guide channel 5 is connected with the left air guide hole 6, and the right air guide channel 7 is connected with the right air guide hole 3;

[0036] A server body 1, which is located inside the housing 2 and between the left air guide channel 5 and the right air guide channel 7;

[0037] The fixing frame 8 is located at the top of the housing 2 , and a gas introduction mechanism for inhaling air is arranged inside the fixing frame 8 .

[0038] Furthermore, filters for filtering air dust are installed inside the left air guide hole 6 and the right air guide hole 3.

[0039] Furthermore, the gas introduction mechanism includes a controller 4, a first air guide hole 13 and a second air guide hole 14, the controller 4 is installed on the front surface of the shell 2, the first air guide hole 13 and the second air guide hole 14 are both opened inside the fixed frame 8, and fans 15 are installed inside the first air guide hole 13 and the second air guide hole 14, wherein the fan 15 inside the first air guide hole 13 and the fan 15 inside the second air guide hole 14 have opposite air outlet directions, and both fans 15 are electrically connected to the controller 4.

[0040] Furthermore, a sealing component for controlling the sealing of the first air guide hole 13 and the second air guide hole 14 is provided on one side of the fixed frame 8; the sealing component includes a forward and reverse motor 10 and a baffle 9; the forward and reverse motor 10 is fixed on one side of the fixed frame 8, and a screw 12 is installed on the transmission shaft of the forward and reverse motor 10; the baffle 9 is located on the front surface of the second air guide hole 14, and the top and bottom of the baffle 9 are slidably connected to the fixed frame 8 through slide rails, and a connecting tube 11 is fixed to the front surface of the baffle 9 through a connecting block, and the connecting tube 11 is threadedly connected to the screw 12.

[0041] Specifically, a limit block is set at one end of the screw rod 12 relative to the transmission shaft of the forward and reverse motor 10, one end of the limit block is fixed to the fixed frame 8, and the limit block and the screw rod 12 are rotatably connected through a sleeve to prevent the baffle 9 from falling off the slide rail during movement.

[0042] Specifically, the aperture of the first air guide hole 13 is equal to the aperture of the second air guide hole 14, and an elastic sealing ring is provided on one side of the baffle 9. The diameter of the elastic sealing ring is larger than the aperture of the second air guide hole 14. The use of the elastic sealing ring can further improve the sealing performance of the baffle 9 to the first air guide hole 13 and the second air guide hole 14.

[0043] Through the above technical solution:

[0044] When in use, the controller 4 periodically (equivalent to every certain period of time) controls the forward and reverse motor 10, so that the transmission shaft of the forward and reverse motor 10 drives the screw rod 12 to rotate clockwise and counterclockwise, thereby controlling the baffle 9 to block the first air guide hole 13 and the second air guide hole 14;

[0045] When the baffle 9 blocks the second air guide hole 14, the controller 4 will also issue a stop command to the fan 15 inside the second air guide hole 14. At the same time, the fan 15 inside the first air guide hole 13 will be turned on. At this time, the first air guide hole 13 is in a connected state with the left air guide channel 5 and the right air guide channel 7. Therefore, after the fan 15 inside the first air guide hole 13 is turned on, air will be sucked in from the right air guide hole 3 (when the air enters the right air guide hole 3, it will be filtered by the filter inside the right air guide hole 3, thereby ensuring that the air entering the device is clean). After that, the air will pass through the right air guide channel 7, the first air guide hole 13, and the left air guide channel 5 in sequence and finally be discharged through the left air guide hole 6. When the air is discharged through the left air guide hole 6, the filter inside the left air guide hole 6 will be backblown, thereby removing dust on the filter inside the left air guide hole 6, so as to improve the cleanliness and air intake when the air enters the left air guide hole 6 later.

[0046] When the baffle 9 blocks the first air guide hole 13, the process is opposite to that when the baffle 9 blocks the second air guide hole 14, and will not be described in detail here. The main process can be briefly described as: "air will be sucked in from the left air guide hole 6, and then the air will pass through the left air guide channel 5, the second air guide hole 14, the right air guide channel 7 in sequence and finally be discharged through the right air guide hole 3". The effect of this process is: when the air is discharged through the right air guide hole 3, the filter screen inside the right air guide hole 3 will be backblown, thereby removing dust on the filter screen inside the right air guide hole 3, so as to improve the cleanliness and air intake when the air enters the right air guide hole 3 later;

[0047] With the cooperation of the two, the air flow can flow from the outside of the server to continuously dissipate heat for the server, and the direction of the air flow can be switched regularly. During the switching process, the filter at the initial "air inlet hole" (i.e., the left air guide hole 6 and the right air guide hole 3 in this scheme) can be backblown, thereby improving the cleanliness of the air entering the device, so as to reduce the impact of filter dust on the air intake required for heat dissipation of the device, thereby enabling the server to dissipate heat efficiently for a long time.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
