1. A vehicle air-conditioner comprising:
- a casing forming an air passage through which air flows toward inside of a vehicle cabin;
a first heat exchanger that is housed in the casing and performs a sensible heat exchange between the air flowing in the air passage and a heating medium flowing through the first heat exchanger; and
a second heat exchanger that is housed in the casing and performs a sensible heat exchange between the heating medium flowing through the second heat exchanger and air that has exchanged sensible heat in the first heat exchanger, wherein the first heat exchanger and the second heat exchanger respectively have a plurality of tubes through which the heating medium flows, a longitudinal direction of the plurality of tubes of the first heat exchanger and a longitudinal direction of the plurality of tubes of the second heat exchanger are the same direction as each other, the casing includes, as the air passage, (i) an inside air passage through which inside air flows toward the inside of the vehicle cabin and (ii) an outside air passage through which outside air flows toward the inside of the vehicle cabin, the first heat exchanger and the second heat exchanger are arranged across both of the inside air passage and the outside air passage, and the longitudinal directions of the plurality of tubes of the first heat exchanger and the second heat exchanger correspond to an alignment direction of the inside air passage and the outside air passage.

Abstract
A vehicle air-conditioner has a casing, a first heat exchanger, and a second heat exchanger. The casing forms an air passage through which air flows toward inside of a vehicle cabin. The first heat exchanger is housed in the casing and performs a sensible heat exchange between the air flowing in the air passage and a heating medium. The second heat exchanger is housed in the casing and performs a sensible heat exchange between the heating medium and air that has exchanged sensible heat in the first heat exchanger. The first heat exchanger and the second heat exchanger respectively have a plurality of tubes through which the heating medium flows. A longitudinal direction of the plurality of tubes of the first heat exchanger and a longitudinal direction of the plurality of tubes of the second heat exchanger are the same direction as each other.
