[0026] On the inner cavity walls on both the front and rear sides of the outer shell 1, current-limiting plates 10 are fixed. The current-limiting plates 10 are bent in the middle and the angle between the plate surfaces is an acute angle. Through the structural setting of the current-limiting plates 10, it is beneficial to restrict the flow direction of the air flow, which is beneficial to the realization of the subsequent air flow stirring effect. A fan 11 is fixed on the right side wall of the outer shell 1, and a wind collecting cylinder 12 is fixed on the inner cavity wall on the right side of the outer shell 1.

[0028] The convection mechanism includes a servo motor 3 fixed to the bottom of the inner cavity of the protective shell 2, two support rods 4 and a support block 7. The output shaft of the servo motor 3 is fixed with a rotating shaft 5. The outside of the rotating shaft 5 is rotatably connected with the support rods 4. By setting the rotation connection with the two support rods 4, it is beneficial to the stability of the rotation of the rotating shaft 5 and the stability of the operation of the overall mechanism.

At the same time, through the movable connection of the displacement shaft at the top of the swing rod 8 in the rotating block 6, the up and down swing of the swing rod 8 is completed, which is beneficial to the realization of the air flow stirring function and further beneficial to improving the heat dissipation effect.

[0030] An annular groove is formed on the outer surface of the rotating block 6. Through the setting of the annular groove, it is beneficial to realize the left and right displacement of the displacement shaft in the annular groove, and further beneficial to the stability of the up and down displacement of the convection block 9. The top of the swing rod 8 is rotatably connected with a displacement shaft. The displacement shaft is located in the annular groove and is slidably connected with the annular groove. The swing rod 8 is located between the movable through holes. A convection block 9 extending to the inside of the outer shell 1 is fixed on the right side of the swing rod 8. The convection block 9 has an arched structure that protrudes up and down and is concave in the middle. Through this structural setting, it is beneficial to relieve the blowing force of the air flow on the convection block 9, and further beneficial to increasing the heat dissipation effect of the power supply.

Through the setting of the heat dissipation component 13 and the limiting component 14, it is beneficial to disassemble and assemble the heat dissipation plate 1303, which is beneficial to the convenient use of the device.

[0032] Please refer to Figure 4 Figure 4 , to achieve the convenient disassembly function of the heat dissipation plate 1303, the heat dissipation component 13 in this embodiment includes two left and right baffles 1301 that fit against the top of the housing 1. By arranging the baffles 1301, it is beneficial to provide a top support for the movable rod 1405 and facilitate the subsequent realization of the disassembly function. A plate body 1302 is fixed between the two baffles 1301, and a heat dissipation plate 1303 is fixed inside the plate body 1302. By arranging the heat dissipation plate 1303, it is beneficial to discharge the heat inside the housing 1, and thus beneficial to the heat dissipation of the power supply. A rotating rod 1305 is rotatably connected to the back of the plate body 1302, a rotating knob 1304 is fixed to the back of the rotating rod 1305, and the rotating rod 1305 passes through the fixed block 1401 and is fixed to the axis of the gear 1402.

[0033] By arranging the baffles 1301, it is beneficial for the top of the housing 1 to provide a top support for the heat dissipation component 13, realizing the support of the overall heat dissipation component 13.

[0034] Please refer to Figure 5 Figure 5 , to limit the heat dissipation plate 1303, the limiting component 14 in this embodiment includes a fixed block 1401 fixed to the bottom of the heat dissipation plate 1303. Two movable rods 1405 are rotatably connected to the left and right baffles 1301 respectively, and the tops of the two movable rods 1405 are in contact with the inner cavity wall of the top of the housing 1. By arranging the contact of the movable rods 1405, it is beneficial to prevent the heat dissipation plate 1303 from easily falling off when subjected to an upward force and beneficial to the stability of the overall device. Displacement plates 1403 are fixed to the opposite sides of the two movable rods 1405, limiting plates 1404 are fixed to the tops of the two displacement plates 1403, and a gear 1402 is meshed between the upper and lower displacement plates 1403.

[0035] In this embodiment, the rotating rod 1305 drives the gear 1402 to rotate. Under the action of the meshing force, the displacement plate 1403 is displaced towards the middle, which is beneficial to realizing the clamping restriction of the movable rod 1405 on the heat dissipation plate 1303. At the same time, by arranging the limiting plate 1404, it is beneficial to the stability of the operation of the overall component.

[0036] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0037] The working principle of the above embodiment is as follows:

[0038] The fan 11 is started to send airflow into the housing 1. At the same time, the servo motor 3 is started to drive the rotating shaft 5 and the rotating block 6 to rotate. The annular groove on the rotating block 6 rotates, driving the swing shaft on the top of the swing rod 8 to move left and right, thereby causing the swing rod 8 to swing upward or downward, causing the convection block 9 to swing at an angle. When the airflow passes through the wind collecting tube 12, the power supply is cooled. The airflow is collected by the current limiting plates 10 before and after the power supply. The airflow is stirred by the swinging action of the convection block 9, so that the power supply is subjected to secondary heat dissipation of the airflow. Finally, the airflow is discharged through the heat dissipation plate 1303 on the top plate. When there are many impurities on the heat dissipation plate 1303 that need to be cleaned, the rotating knob 1304 can be turned to drive the rotating rod 1305 to rotate, thereby causing the gear 1402 to rotate. Through the meshing action, the displacement plate 1403 is driven to move toward the middle, so that the movable rod 1405 returns to the right side of the baffle 1301, and then the plate body 1302 is taken out upward as a whole, so that the heat dissipation plate 1303 is disassembled. This device has a simple structure, is easy to use as a whole, and has a good heat dissipation effect.
