Problems solved by technology

[0002] When high-frequency harmonics flow through the reactor, the reactor will generate a large amount of magnetic flux, which will cause local overheating of the reactor or the structural parts of the system cabinet, which will have an adverse effect on the reactor or the system. In addition, the air-core reactor is It is composed of a single coil winding, and there is no iron core in the middle of the coil, which has a large external magnetic leakage and has a great impact on the electromagnetic environment around the reactor.

Abstract

The invention discloses a heat radiation reactor, comprising a heat radiation base and two coil windings, wherein each coil winding comprises two hollow iron columns, coils wound on the iron columns, and clamping plates arranged at the both ends of the coil windings; the heat radiation base is provided with a cooling block and a resin molding body; and the heat radiation base covers the two coil windings. With the adoption of the manner, the heat radiation reactor provided by the invention has the advantages of simple and compact structure, small noise in a working process, high heat radiation property and high vibration attenuation property.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a cooling reactor. Background technique [0002] When high-frequency harmonics flow through the reactor, the reactor will generate a large amount of magnetic flux, which will cause local overheating of the reactor or the structural parts of the system cabinet, which will have an adverse effect on the reactor or the system. In addition, the air-core reactor is It is composed of a single coil winding, and there is no iron core in the middle of the coil, which has a large external magnetic leakage and has a great impact on the electromagnetic environment around the reactor. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a heat dissipation reactor, which can have the advantages of simple and compact structure, low noise during operation, high heat dissipation performance and high vibration attenuation performance.
