Detailed Description
Example 1
As shown in fig. 1-8, a heat dissipation type network cabinet includes a machine body 101 with a central air duct 102 in the middle, and a fan 103 is arranged at the upper end of the central air duct 102. A plurality of side air channels 105 communicated with the central air channel 102 are uniformly distributed in the machine body 101 around the central air channel 102 in an annular shape. The central air duct 103 may be vertically disposed, and the machine body 101 may be provided with multiple layers, each layer including a plurality of side air ducts 105 arranged in an annular shape. A side fan 107 is provided at a position where the side duct 105 communicates with the center duct 102. When the air conditioner is used, the fan 103 and the side fan 107 are started, the side fan 107 pumps the air flow in the side air channel 105 into the central air channel 102, and then the fan 103 pumps the hot air flow in the central air channel 102 out of the machine body 101.
A module storage rack 104 is arranged at one end of the side air duct 105 away from the side air fan 107. The module is placed in the module storage rack 104, after the side fan 107 is started, the airflow dissipates heat of the module, the airflow enters the central air duct 102, and then the airflow is discharged out of the machine body 101 by the fan 103. When the heat generated by a module in a module storage rack 104 is large, the air flow in the corresponding side air duct 105 directly enters the central air duct 102 and is pumped out of the machine body 101, but not enters other side air ducts 105, so that the heat dissipation of other modules can be prevented from being influenced.
A communication air duct which is communicated with the two adjacent side air ducts 105 is arranged in the machine body 101 between the two adjacent side air ducts 105, an air guide pipe 201 is slidably arranged in the communication air duct, and an air inlet 203 is arranged at one side of the air guide pipe 201, which is away from the central air duct 102. And a driving system for removing the baffles 301 arranged at the two ends of the communication air duct when the side fan 107 is damaged, and enabling the air guide pipe 201 to extend into the damaged side air duct 105 of the side fan 107.
When the side air blower 107 in the side air duct 105 is not damaged, the baffle 301 is used for blocking the communication air duct, so that air flows between the adjacent side air ducts 105 are not communicated, and influence of air flows with higher temperature in other side air ducts 105 on module heat dissipation is avoided.
Specifically, the baffle 301 is fixedly connected to a rack one 302. The driving system comprises a controller and a stepping motor electrically connected with the controller, wherein the stepping motor is used for driving the first gear 305 to rotate. Gear one 305 is meshed with gear two 304, gear two 304 is meshed with gear three 303, and gear three 303 is meshed with rack one 302 on one side. Gear one 305 also meshes with gear four 306, gear four 306 meshes with rack one 302 on the other side. Gear four 306 is meshed with gear five 308 and gear five 308 is meshed with gear six 307. A second rack 204 is arranged on one side, close to the central air duct 102, of the air guide pipe 201, and a sixth gear 307 is meshed with the second rack 204.
A temperature sensor 106 electrically connected with the controller is arranged in the side air duct 105.
When the side fan 107 in a certain side air duct 105 is damaged, the hot air in the side air duct 105 cannot be effectively discharged, the temperature in the side air duct 105 can rise, and when the temperature sensor 106 detects that the temperature in the side air duct 105 rises to a set value, the controller controls the stepping motor to drive the first gear 305 to rotate, so that the baffle 301 is removed, and the air guide pipe 201 extends into the side air duct 105 damaged by the side fan 107. Because the air guide pipe 201 is provided with the air inlet 203 on one side away from the central air duct 102, the hot air in the side air duct 105 damaged by the side fan 107 can enter the air guide pipe 201 through the air inlet 203 and then enter the adjacent side air duct 105 through the communication air duct, so that when the side air fan 107 in one side air duct 105 is damaged, the heat dissipation can be carried out on the modules in the side air duct 105.
When the side fans 107 in the two adjacent side air channels 105 are damaged, the two side air channels 105 can extend into the air guide pipe 201 in the same way, so that hot air flows enter the side air channel 105 without damage of the side fans 107 through the sequence of one air guide pipe 201, one communication air channel, the other air guide pipe 201 and the other communication air channel, emergency heat dissipation treatment is performed, and the reaction time is reserved for maintenance personnel.
Example two

The heat conduction plate 111 is internally and uniformly provided with heat conduction air channels communicated with the side air channels 105. By placing the modules in the storage area 112 such that each module has a pair of heat-conducting plates 111 for heat dissipation, the interaction between the different modules due to the difference in heat generation amount can be avoided.

This allows the air flow in the heat conduction channels through each pair of heat conduction plates 111 to be non-intercommunicated in the area of the module storage rack 104, thereby avoiding that the air flow with higher temperature will affect other modules.
Through setting up the heat conduction board 111 that laminates with the module surface to set up the heat conduction wind channel in heat conduction board 111 inside, can increase heat radiating area, thereby improve the radiating effect to the module.

The two ends of the wedge 116 are fixedly connected with a first slider 115 and a second slider 120 respectively. Side wedges 117 are slidably mounted in the module storage rack 104 on two sides of the wedge 116, which are provided with inclined planes, the side wedges 117 are fixedly connected with connecting rods 118, and springs 119 are connected between one ends of the connecting rods 118, which are away from the side wedges 117, and the module storage rack 104. The connection rod 118 is fixedly connected with the heat conductive plate 111. The adjustment mechanism also includes a drive mechanism for driving the sliding of wedge 116.
The wedge 116 is driven to slide by the driving mechanism, so that the wedge 116 pushes the side wedge 117 to move, and the side wedges 117 on two sides can move towards or away from each other under the action of the first spring 119 and the wedge 116, so that the purpose of adjusting the distance between the connecting rods 118 on two sides is achieved, and the distance between each pair of heat conducting plates 111 is adjusted. Spring one 119 is selected to be able to bear the weight of the module.
Specifically, the module storage rack 104 is provided with threaded holes that communicate with the slides 114. The driving mechanism comprises a screw 113 arranged in the threaded hole, and the screw 113 abuts against the first sliding block 115. A second spring 121 is connected between the second slider 120 and the slideway 114. By screwing the screw 113, the screw 113 can push the wedge 116 to move, and the wedge 116 can be helped to return under the action of the second spring 121.
The filter screen 122 covering the heat-conducting air duct is installed on the machine body 101, so that dust, foreign matters and the like can be prevented from entering the heat-conducting air duct, and the heat-conducting air duct is prevented from being blocked.
Example III
Further, one end of the air guide pipe 201 is connected with a guide pillar 205 through a third spring 206, the guide pillar 205 is fixedly connected with a butt joint pipe 207, and a corrugated pipe 208 is connected between the butt joint pipe 207 and the air guide pipe 201. The internal passage 209 of the butt joint pipe is communicated with the internal passage 202 of the air guide pipe through a corrugated pipe 208.
By arranging the butt joint pipe 207, when the side fan 107 in one side air duct 105 is damaged, the air guide pipe 201 extends out, and the butt joint pipe 207 is propped against the baffle 301 which is not removed at the other side of the side air duct 105 under the elastic force of the spring III 206. When the baffle 301 is removed due to damage to the side air blower 107 in the adjacent side air duct 105, the abutting pipe 207 will extend into the adjacent communication air duct on the other side under the spring force of the third spring 206, so as to facilitate the formation of an airflow flow sequence of one of the air guide pipes 201, one of the communication air ducts, the other air guide pipe 201, and the other communication air duct.
