Efficient heat dissipation electric power cabinet for electric power engineering

Abstract

The invention discloses an efficient heat dissipation electric power cabinet for electric power engineering. The cabinet comprises a base, and supporting legs are respectively fixed at four corners of the bottom surface of the base. According to the efficient heat dissipation electric power cabinet for the electric power engineering of the invention, each electric component is installed in an independent cylinder, so that the purpose of directly cooling each electric component in a one-to-one manner can be achieved, and the circulation process of cooling water in an inner cavity of a first arc-shaped plate can be achieved through a submersible pump, so that the cooling effect on air circulating in a ventilation pipe is effectively achieved; the air blown to the electrical components through the ventilation pipe is cooled, the heat dissipation effect of the electrical components is improved; slow rotation of each cylinder can be achieved at the same time through a motor, the air can be blown to each part of the electrical components in all directions, the heat dissipation effect of the electrical components is further improved; and in addition, due to the function of blowing air around the electric components in all directions, the amount of dust adsorbed on the electric components can be effectively reduced.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to a high-efficiency heat dissipation power cabinet for electric power engineering. Background technique [0002] With the continuous development of intelligent power distribution, the requirements for power cabinets are getting higher and higher, such as PLC control cabinets, frequency conversion cabinets, etc., more and more precision components and power devices are used inside the power cabinets, and the more precise The more components have higher requirements on the use environment, such as the requirements on temperature, humidity, dust and other environments, especially the requirements on temperature. The high-power devices in the power cabinet will release a lot of heat when they work, and the heat must be dissipated in time. If the heat dissipation is not good, it will damage the service life and safety of the power devices. The current power cabinet adopts fan ...

Problems solved by technology

The high-power devices in the power cabinet will release a lot of heat when they work, and the heat must be dissipated in time. If the heat dissipation is not good, it will damage the service life and safety of the power devices.

The current power cabinet adopts fan cooling method to collectively dissipate heat and cool down all the electrical components in the power cabinet. However, due to the limited number of fans, only the electrical components near the fan have a better heat dissipation effect, and the electrical components far away from the fan have better heat dissipation. The effect is not good, resulting in uneven heat dissipation inside the power cabinet, which will affect the normal operation of electrical components over time, and in the process of cooling through the wind, even if there is a dust-proof filter, the dust doped in the outside air will enter more or less In the power cabinet, most of the dust is adsorbed on the electrical components, causing the electrical components to heat up and seriously affecting the normal operation of the electrical components
