Buried waterproof heat dissipation type electrical cabinet

Abstract

The invention discloses a buried waterproof heat dissipation type electrical cabinet which comprises a foundation, wherein an equipment groove is formed in the upper end face of the foundation, a cover plate is installed at a groove opening of the equipment groove, an electric power element is installed in the equipment groove, and a heat exchange pipe is arranged outside the electric power element in a winding mode. According to the invention, when the power element works at a high load and generates a large amount of heat in a short time, a driving agent absorbs the heat to cool the equipment groove again, and meanwhile, the driving agent drives a movable plate to move downwards to generate high pressure in a driving area and generate negative pressure in a driven area after absorbing the heat, so that the cooling liquid in the driving area flows through a heat exchange pipe, then heat dissipation and cooling can be further carried out on the power element, and the power element is prevented from being damaged due to overheating.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an underground waterproof and heat dissipation electrical cabinet. Background technique [0002] Electrical cabinets are generally used for the control of large-scale electrical equipment or power transfer. In order to save space and ensure electricity safety, some electrical cabinets are usually installed underground. This method can also prevent the fire from spreading to other equipment when the electrical cabinet fails and catches fire. , At the same time, due to the less underground air circulation, the fire in the electrical cabinet is easier to control. [0003] However, when the electrical cabinet is used, it will gradually emit heat according to its operating load, especially at night and other peak electricity consumption periods, when the electrical cabinet operates at high load and emits a large amount of heat in a short period of time. If it cannot be dis...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the traditional buried electrical cabinet in the prior art is used, a large amount of heat energy is generated in a short period of time during the peak period and cannot be discharged in time, thereby affecting the normal use of the power components inside the electrical cabinet. In the installation groove of the electrical cabinet, there is a shortcoming that accumulated water is easy to corrode the shell of the electrical cabinet, and a buried waterproof and heat-dissipating electrical cabinet is proposed.
