The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits. The distribution cabinet provides protection, monitoring and control for the circuit. It has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function and no restrictions on the site. It is widely used, but the distribution cabinet will generate heat after use, and the internal temperature of the distribution cabinet will rise. Excessive temperature will seriously affect the service life of the internal circuit components. Therefore, a heat sink is used to dissipate the heat of the distribution cabinet.

[0003] In the existing patent 202210593475.0, a heat dissipation distribution cabinet is disclosed, including a cabinet, and a heat conducting plate installed inside the cabinet, a partition is provided on one side of the heat conducting plate, a plurality of heat dissipation pipes are provided on the partition, and a fan is installed on the top of the cabinet. The present invention can accelerate the speed of heat dissipation inside the cabinet through the arrangement of the heat conducting pipe, the heat conducting plate, the fan, the dustproof plate and the first through hole, avoid the accumulation of heat inside the cabinet and improve the heat dissipation effect, and when in use, the heat dissipated by the equipment installed on the heat conducting plate and the heat inside the cabinet are transferred to the heat dissipation pipe through the heat conducting plate, and then the fan is used to blow air to the plurality of heat dissipation pipes, thereby cooling the heat dissipation pipe, and the air entering and exiting the cabinet will be discharged through the first through hole, thereby completing the heat dissipation process, and during the cooling process, the partition will divide the interior of the cabinet to prevent the air entering from the outside from blowing into the equipment installed on the heat conducting plate.

[0004] In the above structure, heat dissipation inside the cabinet can be achieved, but the structure is relatively complex. The gathering of multiple devices will generate more heat around the cabinet, which is not conducive to the discharge of heat inside the cabinet. Instead, it will increase the temperature of the cabinet and reduce the service life of the equipment and the distribution cabinet. Utility Model Content

[0006] Based on the above purpose, the utility model provides a heat dissipation structure of a distribution cabinet, including a cabinet body, a heat dissipation port is opened on the cabinet body, a cover plate is slidably installed on the cabinet body at the heat dissipation port, a dustproof plate is slidably installed on the cabinet body at the heat dissipation port, the cover plate and the dustproof plate are symmetrically arranged, a driving mechanism is installed on the cabinet body, a transmission assembly is arranged on the cabinet body, the driving mechanism drives the cover plate and the dustproof plate to move through the transmission assembly, a heat dissipation assembly is installed on the cabinet body, and the heat dissipation assembly is used to dissipate the heat in the cabinet body, wherein when the temperature in the cabinet body rises, the dustproof plate is forced to slide to the heat dissipation port to reduce the temperature in the cabinet body, and the cover plate is forced to be hidden in the cabinet body.

[0011] Preferably, the dustproof plate is provided with a plurality of densely arranged heat dissipation and dustproof holes, and the heat dissipation and dustproof holes prevent dust from entering the cabinet.

[0012] The beneficial effects of the utility model are as follows: the dustproof plate and the cover plate are installed at the corresponding positions of the heat dissipation port, and the driving mechanism and the transmission component are matched and installed on the cabinet. When the temperature inside the cabinet is high, the driving mechanism is started, and under the action of the transmission component, the cover plate and the dustproof plate are driven to move in opposite directions synchronously, so that the cover plate is gradually hidden inside the cabinet, and at the same time, the dustproof plate is forced to be exposed to cover the heat dissipation port.
