Zusammenfassung: | PURPOSE:To efficiently cool electric parts by providing a separating plate at the nozzle, which separates an electric parts chamber from a heat-exchange chamber. CONSTITUTION:A cylindrical nozzle 72 for forming a passageway for air sent by a blower has a separating plate 72B separating an electric parts chamber in which electric parts are placed from a heat-exchange chamber in which a heat exchanger is placed. With this arrangement in a heat exchange unit, the heat of the electric parts is easily transmitted to the separating plate 72B, partition part 72C, and nozzle part 72A, since these parts are integrally formed of metal; moreover the nozzle 72 is cooled by the air passing through the nozzle part 72A. As a result, the electric parts can be cooled efficiently. |
