Title:
ELECTRIC POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/070715
Kind Code:
A1
Abstract:
A housing (2) of an electric power source device (1) has a front face panel (21) having formed therein an air suction hole (33), a rear face panel (22), two side face panels (23, 24), a bottom plate (25), a top plate (26) having formed therein an air discharge opening (36), and a partition plate (28). The partition plate (28) partitions the space in the housing (2) into a front face-side space (30) and a rear face-side space (31). The partition plate (28) has an air flow opening (32) for interconnecting the spaces (30, 31). The electric power source device (1) has, in the front face-side space (30), a capacitor (56), a heat sink (52) having a cooling hole (53) formed therein, a semiconductor element (51) placed on the surface of the heat sink (52), an air discharge device (81) capable of discharging air in the rear face-side space (31) to the outside of the housing (2), and a leading member (91) for interconnecting the air flow opening (32) and one opening of the cooling hole (53).
