Novel electric reactor having iron core structure with cooling fins

Abstract

The invention discloses a novel electric reactor having an iron core structure with cooling fins. The novel electric reactor having the iron core structure with the cooling fins. The novel electric reactor comprises an upper iron yoke, an iron core column, a lower iron yoke an d a framework, wherein the iron core column is fixed in the framework; the upper iron yoke and the lower iron yoke are separately fixedly mounted at the upper end and the lower end of the framework; the upper iron yoke is fixedly connected with an upper iron corner through an upper yoke window screw; the lower iron yokeis fixedly connected with a lower iron corner through a lower yoke window screw; and the cooling fins are further arranged on the upper surface of the upper iron yoke. The novel electric reactor having the iron core structure with the cooling fins has the advantages of low temperature rise, high efficiency, attractive appearance and the like, and is convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a novel reactor with an iron core structure and cooling fins. Background technique [0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space where it stands, so the current-carrying electrical conductors are inductive in the general sense. However, the inductance of the current-carrying straight conductor is small, and the magnetic field generated is not strong. Therefore, in the actual reactor, the wire is wound into a helical tube form, which is called an air-core reactor; Inserting the iron core is called iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductors (inductors) and capacitive reactances (capacitors) are collectively referred to as reactors. However, since inductors existed first in the past and were called...

AI Technical Summary

Problems solved by technology

[0006] The temperature rise of the reactor body in the prior art is relatively high. In the design process, the method of increasing the cross-sectional area of ​​the wire is generally used to control the temperature rise. In this way, it is difficult to control the cost of the material and other objective shortcomings; the cost of the material is too high and the efficiency is low; In the design process, the relationship between the thermal load effect and the surface area of ​​the reactor body and the heat dissipation area is not considered.
