A power cabinet with an adjustable mounting structure

Abstract

A power cabinet with an adjustable installation structure, including an induced draft fan assembly on the top of the cabinet body, a plurality of rotating disk assembly components arranged from top to bottom inside the cabinet body, and the outer sides of the left and right side panels of the cabinet body are fixed There is a splint, and the splint is enclosed with the corresponding side plate to form a ventilation cavity. The top of the left ventilation cavity is connected to the atmosphere, and the right ventilation cavity is provided with a ventilation pipe. The upper end of the ventilation pipe is connected with the induced draft fan assembly. There are a plurality of air outlet holes from the bottom. Each rotary disc group includes a ventilation tube, No. 1 and No. 2 rotary discs with the same structure. Electronic components are fixed on the outer wall of the ventilation tube. , The inner wall of the installation through hole on the right side plate is matched, the inner side of the left rotating disk is connected with the inner side of the right rotating disk through a ventilator, and a through groove is opened in the center of the rotating disk, and the two ends of the through groove are respectively It communicates with the ventilation cavity and the ventilator. This design realizes efficient heat dissipation of all electronic components in the cabinet and avoids wind loss.

Description

technical field [0001] The invention belongs to the field of electric power engineering, in particular to a power cabinet with an adjustable installation structure. Background technique [0002] With the continuous development of power distribution intelligence, 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 power cabinets, and the more precise The higher the requirements for the use environment of components, such as the requirements for temperature, humidity, dust and other environments, especially the requirements for temperature. The high-power devices in the power cabinet will release a lot of heat when they work, and these heat must be dissipated in time. If the heat dissipation is poor, it will damage the service life and safety of the power devices. [0003] At present, the power cabinet usually adopts the method...

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.

[0003] At present, the power cabinet usually adopts the cooling method of the induced draft fan to collectively dissipate heat and cool down all the electrical components inside it. However, due to the limited number of induced draft fans, only the electrical components on the side close to the induced draft fan have a better heat dissipation effect, and those far away from the induced draft fan The heat dissipation effect of electrical components is not good, resulting in uneven heat dissipation inside the power cabinet, which will affect the normal operation of electrical components over time, and the existing device lacks auxiliary heat dissipation devices for cables, resulting in a lot of heat accumulated at the cables, causing safety problems.
