Title:
INVERTER-INTEGRATED ELECTRIC COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2012/056983
Kind Code:
A1
Abstract:
Provided is an inverter-integrated electric compressor that utilizes an inexpensive and simple structure to effectively cool high heat-producing electrical components disposed on a control circuit board, and that can simultaneously be made more compact and lighter. A control circuit board (25) constituting an inverter (21) serves as a thermally-conductive substrate. One surface of the control circuit board (25) is installed in a heat transferable manner on a heat-dissipating planar part (31) disposed on a housing (2), while heat-producing electrical components (39) are disposed in a heat transferable manner on the other surface of the control circuit board (25). The control circuit board (25) is provided with a substrate body (41) comprising an insulator, and heat-conducting through members (42) comprising a good thermal conductor filled through in the thickness direction of the substrate body (41). One end of the heat-conducting through members (42) is positioned in a heat transferable manner on the heat-dissipating planar part (31), and the electrical components (39) are positioned in a heat transferable manner on the other end.
