AUTOMOBILE AIR-CONDITIONING DEVICE

PURPOSE:To make it possible to efficiently conduct air-condition in the passenger compartment, irrespective of start and stop of an engine by attaching an electronic cooling element to one end part of a heat pipe coupling between a communication dust and the outside of the passenger compartment so as to communicate the heat absorbing part side of the electronic cooling element with the inside of the communication dust while communicating the heat radiating part side thereof with the outside of the passenger compartment. CONSTITUTION:Air W1 from the passenger compartment or ambient air W2 sucked through an intake-air port 4 or 5 is turned into cool air W3 by being cooled under cooling action of heat absorbing fins 13 provided on a metal plate 12c serving as a heat absorbing part of an electronic cooling element 12 in a communication duct 6, and is then blown into the passenger compartment from a blow-out port 3 so that the cool air W21 conducts air-condition in the passenger compartment. During cooling, the temperature of the metal plate 12b side serving as a heat radiating part of the electronic cooling element 12 becomes high, but this temperature is radiated through the contact between heat radiating fins 15 coupled to heat radiating fins 14 provided on the metal plate 12b through the intermediary of a heat pipe 11, and the ambient air. With this arrangement, cooling action by the air absorbing part 12c may be always ensured, thereby it is possible to effectively conduct air-condition.
