The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions where the load is relatively dispersed and there are fewer circuits. It distributes the electrical energy of a circuit of the upper-level distribution equipment to the nearest load.

[0003] A power distribution cabinet usually contains multiple electronic devices, which will generate a lot of heat when working at high load for a long time. If the heat is not dissipated in time, it will continue to accumulate in the cabinet, causing the working environment temperature of the electronic devices to rise, affecting their normal operation.

[0014] 1. The heat dissipation device for the power distribution cabinet is provided with an air inlet, an air outlet, a dust screen, a connecting strip, a motor, a fan blade and a heat dissipation outlet. The fan blade is rotated by starting the motor so that outside air enters from the air inlet and flows into the cabinet from the air outlet. Thus, the circulation speed of the air inside the cabinet is accelerated by the simultaneous rotation of multiple fan blades, and the high-temperature gas is discharged from the heat dissipation outlet, thereby reducing the temperature and ensuring the normal operation of the electronic components. When the fan blades rotate, the dust screen can prevent dust from entering the cabinet along with the air, thereby preventing dust from causing a short circuit. The staff can pull the dust screen to slide the connecting strip out of the slide rail to complete the removal of the dust screen, thereby facilitating the staff to clean and replace the dust screen and avoiding dust clogging the mesh holes and affecting air circulation due to long-term use.

[0015] 2. The heat dissipation device for the power distribution cabinet is provided with a telescopic rod, a buffer spring, a protective plate, a movable handle, a fixed block, a V-shaped groove, a groove, a connecting spring and a card block. When the side of the cabinet is hit, the protective plate will be pushed by the impact force generated by the collision, thereby compressing the telescopic rod and the buffer spring, buffering the impact force generated by the collision and avoiding damage to the cabinet. After the bellows is pushed into the bottom plate, the staff can push the movable handle to move in the slide groove, so that the fixed block can squeeze the card block into the groove and compress the connecting spring. When the movable handle moves to the end of the slide groove, the connecting spring rebounds and pushes the card block into the V-shaped groove, thereby fixing the fixed block and the movable handle to prevent the bellows from sliding and falling.
