Heat-dissipation switch cabinet

Abstract

The invention discloses a heat dissipation switch cabinet, which relates to the technical field of switch cabinets, comprising a cabinet body, a cooling fan is arranged on the top of the inner wall of the cabinet, a plurality of air holes are correspondingly provided on the upper bottom surface of the cabinet body and the cooling fan, and the middle part of the side of the inner wall of the cabinet is symmetrical There are horizontal slide rails, and baffles are arranged on the horizontal slide rails. There are multiple strip-shaped cavities inside the baffles and are connected to each other. There are a number of heat dissipation holes on the upper and lower bottom surfaces of the cavities. The pipes are connected to each other. The outer wall of the cabinet is provided with a water pump and a liquid storage bin. The water pump, the liquid storage bin and the pipe are connected in pairs to form a liquid circulation cooling system. The bottom of the cabinet is connected with a cooling plate. The temperature sensor is provided with a controller on the outer wall of the cabinet, and the temperature sensor, the water pump and the cooling fan are respectively connected with the controller. The invention adopts the heat dissipation mode combining liquid circulation cooling and heat dissipation with a heat dissipation fan, and has the characteristics of high heat dissipation efficiency, long service life, simple structure and strong technical versatility.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a heat dissipation switch cabinet. Background technique [0002] In recent years, with the continuous improvement of residents' material living standards, the continuous improvement of my country's industrialization level and informatization level consumes more and more electric energy every year, and the increase in the amount of electricity consumption will inevitably lead to an increase in the current on the transmission line. The increase of the power system will cause more damage to some heating elements in the power system. This situation is especially evident in some of our country's substations. [0003] The heat generated by the electrical equipment itself and the electrical related parts between them and the bus bar or cable is greater than its heat dissipation. In particular, the heating of high-current electrical equipment has been an old problem in power line...

AI Technical Summary

Problems solved by technology

[0005] (1) The cable contacts in the switchgear generate a lot of heat and are located in the corner of the cable room. The air is not easy to flow. There is also a partition on the top to stop the hot air from rising, resulting in the accumulation of heat and hot air. It is difficult to Exhausting the hot air here outside the switch cabinet, the power consumed by the fan is out of proportion to the heat dissipation effect, resulting in energy waste, and at the same time, the high temperature of key components in the switch cabinet will also cause a lot of additional power consumption;

[0006] (2) According to the temperature change of the equipment in operation, the operation of the exhaust fan must be controlled manually, which increases the manpower
