Description

A cooling power distribution cabinet

technical field

The utility model belongs to the field of electric power equipment, in particular to a heat dissipation power distribution cabinet.

Background technique

In the field of power distribution cabinets, due to the installation of a large number of connectors and various electronic components in the power distribution cabinet, and the existence of a large number of wires, the total resistance of the power distribution cabinet is very high, because it will A large amount of heat is emitted, which makes the temperature of the power distribution cabinet suddenly increase, and the power distribution cabinet is often compact in structure, small in space and closed, so the heat dissipation effect of the power distribution cabinet generally cannot achieve the desired effect. Especially during the peak period of use, the failure of the power distribution cabinet to dissipate heat in time can easily lead to damage to components in the power distribution cabinet, and even fire and other accidents.

Utility model content

The purpose of this utility model is to provide an AC low-voltage power distribution cabinet in order to solve the problems mentioned in the above-mentioned background technology.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A heat dissipation power distribution cabinet, comprising a cabinet body, characterized in that heat dissipation windows are respectively provided on the side walls and the top plate of the cabinet body, and a heat dissipation device is arranged in the heat dissipation window, and the heat dissipation device includes an electric fan, and the fan protection cover, a fixed plate, and a movable plate, the fixed plate is fixedly installed on the heat dissipation window, the electric fan is arranged on the side of the fixed plate close to the inside of the cabinet, the fan guard is arranged on the periphery of the electric fan, and the The fixed plate is provided with a rotating shaft in the middle of the side facing the outside of the cabinet, the movable plate is connected to the fixed plate through the rotating shaft, a plurality of first cooling holes are arranged on the fixed plate, and the movable plate is provided with The first cooling holes correspond to the second cooling holes, the power switch of the electric fan is a rotary switch, and one end of the rotating shaft is fixedly connected to the rotary switch.

Compared with the prior art, the beneficial effects of the utility model are as follows: by setting the heat dissipation window on the power distribution cabinet, an electric fan, a fixed plate and a movable plate are sequentially arranged on the heat dissipation window from the inside to the outside, wherein the movable plate and the fixed plate are respectively The first cooling hole and the second cooling hole are provided, and the first cooling hole and the second cooling hole are connected and closed by rotating the movable plate, wherein the power switch of the electric fan is a rotary switch, and one end of the rotating shaft is fixedly connected with the rotary switch. The rotary switch of the electric fan is controlled by the rotation of the movable plate. When the movable plate rotates until the first and second cooling holes are aligned and communicated, the electric fan starts to dissipate heat when it is powered on. The number of cooling windows can be selected according to the temperature, which can not only dissipate heat in a timely and effective manner, but also close the fan and cooling holes when the temperature is low and does not need heat dissipation, which can also achieve energy saving and dust prevention.
