Abstract
This utility model relates to the field of capacitor technology and discloses a capacitor with a heat dissipation structure. The capacitor, a first outer shell, and a second outer shell are provided with a mounting mechanism. An auxiliary mechanism is provided on the top of the capacitor. The mounting mechanism includes a slot and a long plate. Insert plates are fixedly connected to the four sides of the left side of the first outer shell. A movable plate is inserted into the square slot. A connecting seat is fixedly connected to the movable plate on the side away from the second outer shell, and a trapezoidal seat is fixedly connected to the movable plate on the side closer to the second outer shell. This capacitor with a heat dissipation structure, through the insertion and engagement of the insert plates and slots, and the structural design of the trapezoidal seat inserting into the trapezoidal slot, combined with screws fixing the connecting seat and the long plate, enables rapid installation and disassembly of the first and second outer shells. This structure ensures a tight fit between the outer shell and the capacitor to optimize the heat dissipation path, while mechanical locking prevents loosening due to vibration during operation, thus balancing installation convenience and structural stability.
