Document Type and Number:
Japanese Patent JP5681572
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle air conditioning device capable of preventing an air duct between heat transfer tubes from being blocked by frost formation, and heating performance from being degraded, even in the frost formation.SOLUTION: The vehicle air conditioning device 10A includes: a heat pump circuit 2 including an outdoor heat exchanger 13; a switching meas 12A for switching a flow direction of a refrigerant that flows into the heat pump circuit 3, depending on an air cooling operation time or an air heating operation; and a fan 17 which inhales outside air through the outdoor heat exchanger 13. The outdoor heat exchanger 13 includes a pair of headers which horizontally extend, and a plurality of heat transfer tubes arranged therebetween. One or more partition plates for dividing the heat transfer tubes into a plurality of heat transfer tube groups in which a flow direction of the refrigerant is reversed from each other, are installed inside each of the pair of headers. The fan 17 is arranged so that the center of the fan 17 is located in an area occupied by an evaporation downstream heat transfer tube group in the plurality of heat transfer tube groups.
