Energy-saving heat dissipation type low-voltage cabinet

Abstract

The invention relates to the technical field of low-voltage cabinets, in particular to an energy-saving heat dissipation type low-voltage cabinet which comprises a cabinet body, the cabinet body is connected with a cold chamber shell through a connecting frame and a plurality of supporting legs, a cabinet door is installed on the connecting frame, the bottom end of the cold chamber shell is connected with a ground chamber through a supporting plate, and a self-cooling cavity is formed in the ground chamber and internally provided with a self-cooling mechanism. A cooling liquid bin is arrangedin the self-cooling cavity, a cooling pipe is arranged in the cooling cavity, the two ends of the cooling pipe communicate with the interior of the cooling liquid bin, a control pump is installed on the cooling pipe, two main pipes and a plurality of branch pipes are installed in the self-cooling cavity in a communicating mode through an air blower and a suction ventilator, and a plurality of ventilation pipes are installed on the ground chamber in a communicating mode. The other ends of the ventilation pipes extend out of the outside and are provided with a plurality of ventilation openings,filter screen plates are installed at the ventilation openings, secondary filter mechanisms are installed in the ventilation pipes in a sliding mode, the heat dissipation effect is good, energy is saved, meanwhile, the dustproof effect is good, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of low-voltage cabinets, in particular to an energy-saving and heat-dissipating low-voltage cabinet. Background technique [0002] As we all know, the low-voltage cabinet is an auxiliary device used in the power transmission process to control, switch and protect electrical components for safe power transmission. Generally, power supply bureaus and substations use high-voltage cabinets, and then After stepping down the voltage of the transformer, it goes to the low-voltage cabinet, and then to the distribution boxes for each power consumption. The low-voltage cabinet has been widely used in the field of power transmission. [0003] The existing low-voltage cabinet includes a cabinet body, a chamber is arranged in the cabinet body, a plurality of heat dissipation fans are installed in the chamber, a cabinet door is connected to the cabinet body, a ventilation port is provided on the side wall of the cabinet b...

Problems solved by technology

[0004] However, there are still the following defects in the above-mentioned prior art solutions. Although a plurality of cooling fans are convenient to dissipate heat to a certain extent in the cabinet, the plurality of cooling fans will gradually heat up during long-term operation. Not only the cooling effect is poor, but also It consumes more energy, and although the dust-proof board can reduce part of the dust entering the cabinet, the dust-proof effect is not good, and the practicability is low
