Reactor parallel air cooling heat-removal system

Abstract

The present invention discloses a reactor parallel air cooling heat-removal system. The system comprises a cabinet body, and a machine-side reactor and a grid-side reactor arranged at the internal portion of the cabinet body, wherein the machine-side reactor is adjacent to the grid-side reactor, and the machine-side reactor and the grid-side reactor are arranged in parallel at the bottom portion of the cabinet body; the system comprises a fan and a water and wind heat exchanger; the water and wind heat exchanger is arranged at one side close to the machine-side reactor, and a wind cavity is arranged between the water and wind heat exchanger and the machine-side reactor; and the fan is fixed on the water and wind heat exchanger, and an air outlet of the fan directly faces an air inlet of the water and wind heat exchanger. The reactor parallel air cooling heat-removal system can effectively perform cooling, and is low in cost and high in reliability.

Description

technical field [0001] The invention relates to the technical field of device heat dissipation, in particular to a parallel air-cooled heat dissipation system for reactors. Background technique [0002] As the power level of electrical cabinets increases, the heat dissipation of electrical equipment becomes more and more important, especially for heat dissipation solutions such as reactors or transformers that generate large amounts of heat. If the heat dissipation problem of reactors with high heat generation cannot be effectively solved, not only will the reactors themselves be overheated and damaged, but also the heat dissipation of the entire cabinet will deteriorate, affecting the reliability of other thermally sensitive components. [0003] In the prior art, there are mainly the following types of heat dissipation solutions for reactors with high heat generation: [0004] Existing technology 1. Sacrifice the protection level of the cabinet body, open holes on the door...

AI Technical Summary

Problems solved by technology

This solution, compared with the above prior art 1 and prior art 2, solves the problems of the protection level of the cabinet being destroyed, the reactor with the built-in water cooling plate has high cost and low reliability, etc., but it also has some other disadvantages, One is that the water-air heat exchanger is installed on the front door of the cabinet, which causes the front door panel of the cabinet to protrude and affect the appearance; the other is that it adopts the method of installing the reactor on the machine side and the reactor on the grid side up and down. Due to the weight of the reactor The reactor located above is very inconvenient for installation and subsequent maintenance; the third is that the cooling air turns into hot air after passing through the reactor below, which is not conducive to the heat dissipation of the reactor above and other heat-sensitive components
