[0013] The technical effects and advantages of the present application are as follows:

[0014] In the present application, the capacitor body is connected with the driving device, so that the capacitor body can supply power to the driving device. The driving device is started by operating the switch by the staff, and drives the fan to rotate, thereby generating upward air force. When the capacitor body operates, the high temperature generated inside is diffused outward. The heat is transferred through the shell and the heat sink. The heat is transferred to the heat sink. The fan blows upward, blows the heat sink, and cools the heat sink. The heat of the capacitor body can be quickly discharged.
