Abstract
In a vehicle air conditioner, an electrical heating member is disposed integrally with a heating heat exchanger including a core portion and upper and lower tanks. An electrical connection portion of the electrical heating member is disposed on a downstream air side of the lower tank of the heating heat exchanger. Therefore, the lower tank of the heating heat exchanger can restrict water from being covered onto the electrical connection portion of the electrical heating member. Thus, an electrical short circuit in the electrical connection portion is prevented, while air flow resistance is restricted from being increased.
Claims14
An air conditioner for a vehicle comprising:
- an air conditioning case for defining an air passage through which air flows;
- a heating heat exchanger disposed in said air conditioning case for heating air passing therethrough, said heating heat exchanger including
- a core portion having a plurality of tubes through which a fluid flows and a plurality of fin members connected to said tubes, and
- a first tank portion disposed at a lower side of said core portion to communicate with said tubes;
- and
- an electrical heating member disposed integrally with said heating heat exchanger, wherein:
- said electrical heating member includes an electrode plate portion integrated with said core portion, and an electrical connection portion through which electrical power of an outer electrical circuit is supplied to said electrode plate portion;
- said electrical connection portion is disposed on a downstream side position of said first tank portion in an air flow direction;
- and
- said electrical connection portion has a bottom surface higher than a bottom surface of said first tank portion by a predetermined distance.
