POWER MODULE AND AIR CONDITIONER

摘要

An efficient heat diffusing structure comprising a power module having a mounting substrate that has a high thermal conduction efficiency. The mounting substrate is comprised of a mounting surface on which an electric power circuit for controlling electric power is mounted, and a heat dissipating surface that has a corrugated section formed thereon that serves to dissipate heat. This heat diffusing structure allows the size of the device to be reduced, and also allows costs to be reduced.
