  • Publication number: 20200196491
    Abstract: An inverter device includes a casing, a heat source element, a heat dissipation structure and a fan. The casing has a base and a cover covering the base. An internal and an external surface are defined on the cover. The inner surface is disposed corresponding to the base. The heat source element is disposed in the casing and arranged on the base. The heat dissipation structure is thermal connected with the internal surface. The fan is accommodated in the casing corresponding to the heat dissipation structure. An air flow in the casing is accelerated by the fan, and the heat dissipation structure absorbs heat from the air flow in the casing and thermal conductively transfers to the external surface of the cover. A heat dissipation efficiency of the inverter device is thereby improved and the inverter device is thereby more durable.
