[0037] See also Figure 2 and Figure 8 In the figure, the front and rear ends of the heat sink 4 are both fitted with positioning frames 3, and the two positioning frames 3 are fixedly connected to the inner wall of the box body 1; specifically, the setting of the positioning frame 3 facilitates the installation of the heat sink 4 at a designated position in the box body 1 (that is, better heat dissipation is achieved under the premise of ensuring a reasonable layout of the space in the box body 1).

[0038] Working principle: When the server is running, the cooling fan 19 in each of the eight hole slots 6 on the heat sink 4 will operate normally, thereby cooling the components inside the box 1. When the circuit or components inside the box 1 emit smoke due to a fault, the two smoke sensors 30 on the box cover 2 will capture the smoke particles and trigger an alarm signal. Since the servo motor 5 on the mounting base 33 is electrically connected to the two smoke sensors 30, any smoke sensor 30 that captures smoke particles can trigger the servo motor 5 to start working. The output shaft of the servo motor 5 will rotate and drive the connecting shaft 8 to rotate on the U-shaped plate 35. The connecting shaft 8 will drive the four worms 12 thereon to rotate. The four worms 12 will drive the corresponding worm wheels 11 to rotate. The worm wheels 11 will drive the rotary switches on the corresponding inert gas tanks 10 to rotate, and the valves of the four inert gas tanks 10 will all be opened (it should be noted that the servo motor 5 is equipped with a control switch). When the smoke sensor 30 is triggered, the signal will be transmitted to the controller, and the controller will start the servo motor 5. The controller can also control the start and stop of the servo motor 5, that is, the servo motor 5 will stop running after the valves of the four inert gas tanks 10 are opened. This is common knowledge and will not be elaborated on). Then, the inert gas in the inert gas tanks 10 in the four slots 7 can be released outward in the corresponding hole grooves 6 through the L-shaped air ducts 13 on each of them and through the two nozzles 22 on the L-shaped air ducts 13. The inert gas can be blown toward the rear of the interior of the box 1 under the action of eight cooling fans 19, so that an oxygen-deficient environment is formed in the rear of the interior of the box 1, thereby curbing the further development of smoke and fire. Therefore, the heat dissipation device not only plays a role in heat dissipation when the server is operating normally, but also plays a role in extinguishing smoke and fire when the server fails and produces smoke and fire. It integrates the heat dissipation and fire extinguishing mechanisms into one, reducing the occupation of the internal space of the box 1.

[0039] When the connecting shaft 8 is driven by the servo motor 5 to rotate, it will also drive the four gears 14 thereon to rotate, and the four gears 14 will drive the corresponding racks 15 to move upward, and the four racks 15 will drive the connecting plates 16 on them to move upward, and the four connecting plates 16 will drive the connecting rods 17 on them to move upward in the inner wall of the heat sink 4 (in this process, the springs 18 between the four connecting plates 16 and the heat sink 4 will be stretched on the corresponding connecting rods 17), and one of the connecting rods 17 will move upward to leave the front end of the corresponding annular plate 29 The annular plate 29 moves forward without the restriction of the connecting rod 17 and is subjected to the force of the spring 28 (the spring 28 is originally in a compressed state) between the cooling fan 19 and the annular plate 29. The annular plate 29 drives the sleeve 25 to slide forward on the outer wall of the connecting column 24 on the cooling fan 19. The sleeve 25 drives the multiple support rods 27 thereon to move forward. In the process of the multiple support rods 27 moving forward, the front ends of the multiple support rods 27 gradually move away from each other and drive the blades 9 on each of them to move in their corresponding rectangular The plurality of blades 9 will be transformed from the original storage state to the expanded state (it should be noted that the plurality of blades 9 in the storage state will be in the hole groove 6 to the minimum extent, and the air passing through the hole groove 6 will be less blocked, and the normal operation and heat dissipation effect of the heat dissipation fan 19 will not be affected. Because the connecting plate 16 is pulled by the spring 18, the connecting rod 17 and the connecting rod 20 can be prevented from moving upward when the server is operating normally. The blades 9 are unfolded, and only when the connecting shaft 8 rotates can the multiple blades 9 be unfolded through a series of linkage effects). When the heat dissipation fan 19 rotates, it will drive the connecting column 24 to rotate, the connecting column 24 will drive the ring 34 to rotate, the ring 34 will drive the multiple rectangular blocks 26 thereon to rotate, and the multiple rectangular blocks 26 will drive the blades 9 on each of them to rotate. The multiple blades 9 are symmetrically arranged with the multiple blades of the heat dissipation fan 19, that is, the multiple blades 9 will blow a part of the inert gas released by the nozzle 22 in the hole groove 6 toward the front of the inside of the box body 1.

[0040] At the same time, the upward movement of the connecting rod 17 will also drive the concave rod 23 to move upward in the hole groove 6 located above, and the concave rod 23 will drive the connecting rod 20 to move upward in the inner wall of the heat sink 4. Similarly, the upward movement of the connecting rod 20 will also cause the multiple blades 9 in the hole groove 6 located below to unfold. Similarly, the upward movement of the other three connecting rods 17 will also produce the same linkage effect, so that the multiple blades 9 in the other hole grooves 6 can all be unfolded, so that the front of the interior of the box body 1 will also form an oxygen-deficient environment due to the blowing of inert gas, thereby forming an oxygen-deficient environment inside the entire box body 1, further curbing the development of smoke and fire, and further ensuring the effect of extinguishing smoke and fire. The heat dissipation device of the server can play a smoke and fire extinguishing role as soon as the internal circuits or components of the server smoke and catch fire, timely and minimize further damage to the server, and provide convenience for timely remediation of the server.
