Energy-saving heat dissipation type high-low voltage power cabinet

Abstract

The invention belongs to the field of electric power cabinets, and particularly relates to an energy-saving heat dissipation type high-low voltage power cabinet which comprises a bottom plate. The upper surface of the bottom plate is fixedly connected with a cabinet body, the front face of the cabinet body is movably connected with a front cover plate, and the upper surface of the cabinet body is fixedly connected with a sunshade roof. According to the energy-saving heat dissipation type high-low voltage power cabinet, an arc-shaped plate is arranged, when external airflow passes through, the arc-shaped plate guides cold air at the bottom upwards, according to the Bernoulli principle, the baffle plate is opened under the pressure difference effect, the density of the cold air is larger than that of hot air, the cold air naturally sinks, the external airflow pushes the cold air to flow out of the rectangular grooves; under the action of the inclined plate, the cold air rises, the cold air absorbs heat and expands in the equipment, the hot air naturally rises and flows out from the bottoms of the cooling fins, heat in the equipment is taken out accordingly, the temperature in the equipment is controlled through flowing of air inside and outside the electric power cabinet, and the problem that the temperature in a traditional electric power cabinet is prone to being accumulated and rising is solved.

Description

technical field [0001] The invention belongs to the field of power cabinets, in particular to an energy-saving and heat-dissipating high-voltage and low-voltage power cabinet. Background technique [0002] The power cabinet is also called the power distribution cabinet, which is the collective name of the motor control center. It can be used in the occasions where the load is relatively dispersed and there are few circuits, and it can also be used in the motor control center where the load is concentrated and there are many circuits. The main function is to provide protection, monitoring and control to the load. [0003] When the traditional power cabinet is placed outdoors, because the power cabinet is mostly made of metal, in summer, the surface and interior of the equipment are easy to absorb heat, coupled with the heat generated by the internal electrical appliances of the equipment, the power cabinet is very easy to spontaneously ignite at high temperature.

Problems solved by technology

[0003] When the traditional power cabinet is placed outdoors, because the power cabinet is mostly made of metal, in summer, the surface and interior of the equipment are easy to absorb heat, coupled with the heat generated by the internal electrical appliances of the equipment, the power cabinet is very easy to spontaneously ignite at high temperature. Most of the cabinets are metal box structures, lacking heat dissipation devices inside, low heat dissipation efficiency, and poor heat dissipation effect. Generally, heat dissipation devices are installed on the outside, but the heat dissipation device will also consume part of the power, wasting energy, and the heat dissipation device will also generate heat when it is working. heat
