Claims

[Scope of utility model registration request]

A heat exchanger that exchanges heat with refrigerant vaporized through an expansion valve, low-pressure piping that leads the refrigerant from this heat exchanger to a compressor, and electric power that supplies power through a semiconductor element to drive the compressor, etc. An air conditioner comprising a conversion device, a heat absorbing member attached to the semiconductor element, and a heat radiating member that is thermally coupled to the adsorption member and cooled by a refrigerant passing through the low pressure pipe.
