Driver device and air conditioning

Abstract

A driving device (200) that converts electrical energy provided by a power supply into motor-driving electrical energy, comprising: a substrate (1) on which a conductive pattern formed from a metal foil and comprising solder pads (11a, 11b) is provided; a heat-generating component (2) that includes pins (21a, 21b) for connection and is mounted on the substrate (1) by solder bonding the pins (21a, 21b) to the solder pads (11a, 11b); electronic components (13, 14) that are electrically connected to the heat-generating component (2) via the conductive pattern; a housing (3) formed from metal that surrounds the substrate (1); and heat dissipation elements (4a, 4b) for dissipating heat generated by the heat-generating component (2). The heat dissipation elements (4a, 4b) are in contact with the housing (3), with the solder pads (11a, 11b) and with the pins (21a, 21b).
