Heat-dissipation reactor

Abstract

The invention relates to a heat-dissipation reactor. The heat-dissipation reactor comprises an iron core and a conductive ring, wherein the conductive ring is bent to form a spiral shape and is woundaround the iron core, the conductive ring comprises inner rings and outer rings, the inner rings are inwards attached onto the iron core, the outer rings are outwards expanded, the inner rings and theouter rings are sequentially arranged at intervals along a longitudinal direction, insulation gaps are reserved between the outer rings and the inner rings, and the insulation performance is guaranteed to be stable. The conductive ring is exposed out of air and is in direct contact with the air to dissipate heat, cooling gaps are reserved between the outer rings and a line core, turbulence is formed between the outer rings and the inner rings by combining a fan blowing towards the conductive ring, heat generated by the conductive ring during working can be timely dissipated, and the integralheat dissipation performance is improved. Compared with a traditional technology of which each circle of a solenoid is sequentially attached, the heat-dissipation reactor provided by the embodiment ofthe invention has the advantages that the insulation gaps are formed between the inner rings and the outer rings which are adjacent to each other, the eddy-current loss of an effect of a magnetic field on the conductive ring after energization of the conductive ring is reduced.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a heat dissipation reactor. 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 it occupies. All electric conductors that can carry current have inductance in the general sense. However, the inductance of the long straight conductor is small after electrification, and the magnetic field generated is not strong. Therefore, the existing reactor is generally wound into a solenoid with a wire covered with insulation, which is called an air-core reactor. Later, in order to make the solenoid have greater inductance, an iron core is inserted into the solenoid, which is called an iron core reactor. In the existing iron core reactor, each coil of the solenoid itself sticks to the spiral in turn, and the solenoid sticks to the outside of the iron core. In this way, although the structure b...

Problems solved by technology

In the existing iron core reactor, each coil of the solenoid itself sticks to the spiral in turn, and the solenoid sticks to the outside of the iron core. In this way, although the structure between the solenoid and the iron core is stable, the heat generated by the solenoid is large Part of it will be transferred to the iron core, and the heat will accumulate in the iron core for a long time and cannot be dissipated, and the heat dissipation effect is poor.

Furthermore, if the distance between two adjacent coils of the solenoid is too small, eddy current loss will be formed in the conductor solenoid due to the action of the magnetic field after the solenoid is energized.
