The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] like Figures 1 to 13 As shown, a server heat dissipation control system includes a base plate 1 and a cabinet 2 mounted on the base plate 1. A support plate 4 for supporting a server 3 is installed inside the cabinet 2. An exhaust fan 5 and a guide assembly 6 driven by the exhaust fan 5 are installed below the support plate 4.

The guide assembly 6 includes an air supply plate 61. An air intake assembly 9 is installed on one side of the cabinet 2. The exhaust assembly 7 blows air into the cabinet 2 through the spiral blades 71 driven by the exhaust fan 5. The cooling assembly 8 cools the air. The guide assembly 6 dissipates heat from the server 3 by guiding the cold air through the air supply plate 61. The air intake assembly 9 exhausts hot air from inside the cabinet 2.

[0038] It is worth mentioning that, such as Figure 7 and Figure 8As shown, the air extraction assembly 7 further comprises a partition 72 fixedly arranged in the cabinet 2, a plurality of passages 73 fixedly arranged at the bottom of the cabinet 2, a filter screen 74 fixedly arranged at one end of the passages 73, and the helical blades 71 are fixedly arranged in the passages 73. The air extraction fan 5 is arranged on the partition 72. In use, when the server 3 needs to be cooled, the air extraction fan 5 is rotated. Negative pressure is generated below the air extraction fan 5, and external air is extracted into the cabinet 2 through the passages 73 and the helical blades 71, and then is blown to the server 3 by the air extraction fan 5 for cooling.

[0039] It should be emphasized that, as Figure 9 shown, the cooling assembly 8 comprises a water inlet pipe 82 and a water outlet pipe 83 fixedly connected between the helical blades 71, and a cooling tank 84 fixedly arranged between the water inlet pipe 82 and the water outlet pipe 83. The cooling tank 84 is provided with a water pump on one side. The helical blades 71 are provided in a hollow structure and can accommodate a cooling medium. In use, when the air flows into the passages 73, the water pump flows water into the helical blades 71 through the water inlet pipe 82. After heat exchange with the air, the water flows into the cooling tank 84 through the water outlet pipe 83, is cooled, and then flows into the helical blades 71 again to circulate, so that the air is fully heat-exchanged under the action of the helical blades 71, and the cooling effect is improved.

[0040] It should be further explained that, as Figure 3 shown, the bearing plate 4 is provided with a through slot 10 and a plurality of heat dissipation holes 11.

[0041] It is worth mentioning that, as Figures 10 to 13As shown, the guide assembly 6 further comprises a rotating shaft 62 rotatably arranged on the cabinet 2, a gear 63 fixedly arranged on the rotating shaft 62, a blowing cavity 64 formed in the blowing plate 61, a first rotating shaft 65 fixedly arranged on the shaft of the air suction fan 5, a first bevel gear 66 fixedly arranged on the first rotating shaft 65, a second rotating shaft 67 rotatably arranged on the cabinet 2, a second bevel gear 68 fixedly arranged on one end of the second rotating shaft 67, a cam 69 fixedly arranged on the other end of the second rotating shaft 67, a rack 610 slidably arranged in the cabinet 2, a guide rod 611 fixedly arranged on the rack 610, a spring 612 fixedly arranged between the cabinet 2 and the rack 610, the rotating shaft 62 is fixedly connected with the blowing plate 61, the first bevel gear 66 is engaged with the second bevel gear 68, the guide rod 611 cooperates with the cam 69, the blowing cavity 64 cooperates with the through slot 10, in use, when the air suction fan 5 rotates, the first bevel gear 66 and the second bevel gear 68 drive the second rotating shaft 67 and the cam 69 to rotate, the cam 69 drives the rack 610 to move upwards while pressing the spring 612, the gear 63, the rotating shaft 62 and the blowing plate 61 are driven to rotate downwards, so that the front end of the blowing plate 61 is flush with the bearing plate 4, at this time, the cold air flows into the through slot 10 from the blowing cavity 64, and flows out from the other end of the through slot 10, thereby sufficiently cooling the bottom of the server 3, at the same time, under the action of the blowing plate 61, the cold air flows along the lower surface of the blowing plate 61 to the space between the bearing plate 4 and the server 3 for heat dissipation; when the cam 69 and the rack 610 are disengaged, the spring 612 drives the rack 610 to descend, thereby driving the blowing plate 61 to flip upwards, so that there is a gap between the blowing plate 61 and the bearing plate 4, so that when the air suction fan 5 blows air, the air can flow upwards more, thereby ensuring that the server 3 above also has the same heat dissipation effect.

[0042] Further, as shown in Figure 10 the air suction assembly 9 comprises a plurality of return air plates 91 fixedly arranged in the cabinet 2, a plurality of mounting grooves 92 formed in the cabinet 2, a return air fan 93 arranged in the mounting groove 92, and a filter plate 94 fixedly arranged on the mounting groove 92, wherein the return air fan 93 is turned on and off at the same time as the air suction fan 5, in use, the cold air flows to the space below the bearing plate 4 under the guidance of the blowing plate 61, and then flows to the return air fan 93 under the guidance of the return air plate 91, and the return air fan 93 discharges the hot air outside the cabinet 2.

[0043] In addition, as shown in Figure 9As shown, the flow direction of air on the spiral blade 71 is opposite to the flow direction of water in the spiral blade 71, when the water flows into the spiral blade 71 from the water inlet pipe 82, the water temperature is always the lowest, when the water flows to the other end of the spiral blade 71, the water temperature gradually increases, and when the external air flows into the spiral blade 71 from the channel 73, the temperature difference between the air and the water is the smallest at this time, therefore, the air gradually cools down in the process of continuous flow, so that the air can fully exchange heat.

[0044] Further, as shown in the drawings, Figure 2 The bearing plate 4 is provided with a rubber pad, which protects the server 3.

[0045] Working process

[0046] When the server 3 needs to be cooled, the air suction fan 5 rotates, and the negative pressure is generated below the air suction fan 5, so that the external air is sucked into the cabinet 2 through the channel 73 and the spiral blade 71, at this time, the water pump flows the water into the spiral blade 71 through the water inlet pipe 82, exchanges heat with the air, and then flows into the cooling box 84 through the water outlet pipe 83 to be cooled and then flows into the spiral blade 71 to circulate, then the air suction fan 5 drives the second rotating shaft 67 and the cam 69 to rotate through the first bevel gear 66 and the second bevel gear 68, the cam 69 drives the rack 610 to move upwards, drives the gear 63, the rotating shaft 62 and the air supply plate 61 to rotate downwards, so that the front end of the air supply plate 61 is flush with the bearing plate 4, at this time, the cold air flows into the through slot 10 from the air supply cavity 64, and flows out from the other end of the through slot 10, and fully cools the bottom of the server 3, at the same time, when the air suction fan 5 blows, the cold air flows along the lower surface of the air supply plate 61 to the space between the bearing plate 4 and the server 3 to be cooled; when the cam 69 and the rack 610 are disengaged, the rack 610 descends, drives the air supply plate 61 to flip upwards, and there is a gap between the air supply plate 61 and the bearing plate 4, so that when the air suction fan 5 blows, the air can flow upwards more, so as to ensure that the server 3 above can also be cooled, then the cold air flows to the space below the bearing plate 4, and then flows to the return air fan 93 under the guidance of the return air plate 91, and the return air fan 93 discharges the hot air out of the cabinet 2.
