Abstract

This reactor apparatus is capable of having both the excellent heat dissipating characteristics and insulating characteristics. The heat dissipating characteristics of the reactor apparatus are improved by having a metal plate (300), which has high heat dissipating characteristics, in direct contact with the whole surface of the bottom surface portion (204) of a case (200), which is formed of an insulating resin, and which houses the whole coil (120) of a reactor. A heat dissipating adhesive is applied to and hardened between the bottom surface portion (204) and the metal plate (300). Furthermore, the metal plate (300) is fixed to the bottom surface portion (204) by means of braces (400).

Description

technical field [0001] The present invention relates to a reactor device including a coil. Background technique [0002] In recent years, a plug-in HEV (Hybrid Electric Vehicle, hybrid electric vehicle) or EV (Electric Vehicle, electric vehicle) has gradually become popular. EVs or plug-in HEVs are equipped with on-board charging equipment that converts external AC power into DC and outputs it to the vehicle's battery. [0003] A reactor device including a coil is mounted on an HEV or EV on-board charging facility for improving power factor, smoothing, or the like. [0004] For a reactor device for an on-board charger for HEV or EV, a very high voltage of around 400 volts is applied. Therefore, the coil becomes high temperature due to heat generation. At this time, in order to prevent the coil in the car charger from overheating, it is important to provide the reactor device with very high heat dissipation. At the same time, it is also important to provide reliable elect...
