COOLING STRUCTURE OF ELECTRIC POWER UNIT

摘要

PROBLEM TO BE SOLVED: To provide a cooling structure of an electric power unit which cools a battery module and an inverter with a simple structure while improving rigidity of a plate-like member supporting the battery module or the inverter.SOLUTION: A power source unit 7 includes a center plate 24 which is housed in a case body 21 while sandwiched by opening ends and allows an inverter 12 to be placed thereon. The center plate 24 is formed into an irregular shape in which recesses and protrusions alternately continue. The center plate 24 and the opening ends form communication holes allowing an interior part of the case body 21 to communicate with an exterior part of the case body 21.SELECTED DRAWING: Figure 2
