Title:
放熱機構を有するインバータ装置
Document Type and Number:
Japanese Patent JP6807988
Kind Code:
B2
Abstract:
An inverter device (10) includes a casing (1), a heat source element (2), a heat dissipation structure (3) and a fan (4). The casing (1) has a base (11) and a cover (12) covering the base (11). An internal and an external surface (122) are defined on the cover (12). The inner surface is disposed corresponding to the base (11). The heat source element (2) is disposed in the casing (1) and arranged on the base (11). The heat dissipation structure (3) is thermal connected with the internal surface (121). The fan (4) is accommodated in the casing (1) corresponding to the heat dissipation structure (3). An air flow in the casing (1) is accelerated by the fan (4), and the heat dissipation structure (3) absorbs heat from the air flow in the casing (1) and thermal conductively transfers to the external surface (122) of the cover (12). A heat dissipation efficiency of the inverter device (10) is thereby improved and the inverter device (10) is thereby more durable.
