The surface of the first driven synchronous shaft 204 The first synchronous transmission belt 205 is movably connected, and the surface of the second driven synchronous shaft 206 is movably connected to the second synchronous transmission belt 207. The rear side of the mounting box 1 is fixedly installed with a mounting frame 201, and the motor 202 is fixedly installed on the rear side of the mounting frame 201. The output end of the mounting frame 201 is fixedly connected to the active synchronous shaft 203, and the active synchronous shaft 203 is movably connected to the middle end of the rear side of the mounting box 1. The first synchronous transmission belt 205 and the second synchronous transmission belt 207 are both movably connected to the active synchronous shaft 2 03, the bottom of the first driven synchronous shaft 204 and the second driven synchronous shaft 206 are fixedly installed with a connecting rod 208, the surfaces of the two connecting rods 208 are fixedly installed with a driving bevel gear 209, the ten driving bevel gears 209 are meshed with the surfaces of the ten driven bevel gears 210, and circular shells 214 are fixedly installed on the left and right sides of the inner cavity of the installation box 1 and on the outside of the ten heat dissipation blades 213, and dust filters 215 are fixedly installed on the inner sides of the ten circular shells 214.

[0029] By setting up a heat dissipation mechanism 2, through the output of the motor 202, the active synchronous shaft 203, the first driven synchronous shaft 204 and the second driven synchronous shaft 206 cooperate with each other, so that the connecting rod 208 drives the driven bevel gear 210 to rotate, and the heat dissipation blade 213 rotates, and the air outside the installation box 1 is drawn into the inner cavity of the installation box 1, so that the wind blows through the surface of the power supply card body 4 and dissipates heat.

[0033] When the utility model is working: when the power supply card body 4 is running, the active synchronous shaft 203 rotates through the output of the motor 202. At this time, the active synchronous shaft 203 cooperates with the second synchronous transmission belt 207 and the first synchronous transmission belt 205.
