A heat sinkA is disposed on a circuit board, an air duct is disposed on the heat sink, external cooling air is supplied by the fan attached to the sink air inlet of the heat sink and the air duct inlet of the air duct. Cooling air flowing out of the air duct outlet of the air duct comes into contact with the magnetic component mounted on the circuit board.

Electronic appliance and power conversion apparatus

An electronic equipment cooling device is provided, which has housing in which heat-generating components are housed, and which can cool surfaces of the housing. A blower fan blows air toward the surfaces via a chamber room. An inclined flat plate-like partition portion is provided inside the chamber room so as to distribute a desired amount of air corresponding to a heat generating ratio of the respective surfaces.

Electronic equipment cooling device and power converter having electronic equipment cooling device

Provided is a cool air flow space in which cool air, that is generated by an inner fan disposed inside a housing, flows in the housing. An attachment member mounts a magnetic component on a bottom portion of the housing at a position within the cool air flow space. The attachment member includes a top plate and a pair of legs that extends downward from the top plate and that is fixed to the bottom portion.

Magnetic component cooling structure and power converter having the same

A cooling device includes a plurality of side wall fins formed on an outer surface of a first side wall of a housing, and a plurality of bottom fins formed on a bottom surface of a bottom portion of the housing. A cover member covers the side wall fins and bottom fins from an outer side to form side wall and bottom cooling channels. A chamber is provided that forms a fluid introduction chamber in a direction facing a second side wall so as to communicate with the side wall cooling channel and the bottom cooling channel. A coolant supply device is externally attached to the chamber so as to supply a coolant to the fluid introduction chamber. The side wall fins and the bottom fins are formed in predetermined shapes to adjust an amount of the coolant in the side wall cooling channel and the bottom cooling channel.
