Abstract:
[Problem] To suppress deterioration of air-conditioning efficiency in a vehicle air-conditioning device that cools a motor for driving a blower, using air in a unit introduced by the blower. [Solution] A vehicle air-conditioning device comprises a temperature-adjusted blowing unit that cools or heats air introduced into a housing and blows the air into a vehicle interior, and an air-introducing unit that introduces outside air and/or vehicle-interior air into the housing, the temperature-adjusted blowing unit having a partition wall that partitions the inside of the housing into a first region and a second region, a filter that purifies air passing through the first region and the second region, and a heat exchange unit that cools air that has passed through the filter, the air-introducing unit having a first blowing unit that introduces air into the first region, a second blowing unit that introduces air into the second region, and a drive unit that rotates and drives the first blowing unit and the second blowing unit coaxially, the drive unit being located on the side containing the first blowing unit among the first blowing unit and the second blowing unit and the side containing the first region among the first region and the second region, and the drive unit being provided with a drive unit cooling flow path that guides air between the filter and the heat exchange unit in the first region to the drive unit.
