Ventilation heat radiation device for low voltage complete set device

Abstract

The invention discloses a ventilation heat radiation device for a low voltage complete set device, comprising a cabinet body; the low voltage complete set device is arranged inside the cabinet body; two side walls of the cabinet body are provided with a plurality of heat radiation grids which are uniformly distributed; the outside of the heat radiation grids is provided with a self-dropping blind louver air openings which are fixed on the wall of the cabinet body; the lower ends of the self-dropping blind louvers shield the heat radiation grids; the upper ends of the two sides of the cabinet body are respectively provided with an air inlet and an air outlet; the lower part of the cabinet body is provided with a temperature sensor; and the temperature sensor is connected to the controller. The invention detects the temperature inside the low voltage complete device through the temperature sensor, and transmits the temperature signal to the controller which controls a blower to start up. The heat inside the low voltage complete set device is transmitted out through heat radiation grids, and the self-dropping blind louver air openings are automatically opened. The waterproof housing prevents the rain from going inside the cabinet and guarantees the moisture going inside the cabinet to be discharged through air circulation, which is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a ventilation and cooling device for low-voltage complete equipment. Background technique [0002] In the prior art, due to the intelligentization and intensification of low-voltage complete sets of equipment, a large number of heating components are installed in the cabinet, and the channels and spaces for heat dissipation are limited. The heat emitted by the heating components cannot be discharged in time when they are working, resulting in High temperature accelerates the aging and damage of components and insulating parts in the cabinet, and even causes electrical short circuit accidents in severe cases, affecting the surrounding switchgear, thus affecting the safe and stable operation of the power grid. In view of this, the inventor has developed a low-pressure complete set of ventilation and heat dissipation device that overcomes the above-mentioned d...
