Description

Technical Field

[0002] A reactor is a component used to regulate the energy between inductance and capacitance in a circuit. It is usually used in power systems, and its main function is to control current, voltage and power factor. The reactor can reduce the current in the circuit, stabilize the voltage, eliminate harmonics, etc.

[0003] When using a reactor, in order to ensure that the components will not be damaged by overheating, a heat dissipation structure is usually used for heat dissipation. The heat dissipation structure can use fan cooling, thermal conductive sheets, heat sinks, etc. to effectively dissipate the heat generated by the reactor to keep the components within a suitable operating temperature range. This can improve the reliability and service life of the reactor. However, most common heat dissipation methods are for heat dissipation on the outside of the reactor, and cannot effectively dissipate the heat inside the reactor. The reactor cannot be effectively cooled, and long-term high temperature will also affect the reliability and service life of the reactor. Therefore, a reactor with an improved heat dissipation structure is required. Utility Model Content
