Abstract
In a vehicle air conditioner, a temperature sensor is disposed on a tank of an evaporator to contact the tank. In addition, the temperature sensor is disposed at a tank position separated from a refrigerant inlet and a refrigerant outlet. Accordingly, a downstream space of the evaporator can be effectively used, and the size of the air conditioner can be reduced while the temperature of the evaporator can be accurately detected using the temperature sensor.
Claims8
An air conditioner for a vehicle, comprising:
- an evaporator for cooling air passing therethrough by performing heat exchange with refrigerant flowing therein, the evaporator having a core portion for performing the heat exchange and a tank for distributing refrigerant into and for collecting refrigerant from the core portion;
- a temperature detector for detecting a temperature of the evaporator, the temperature detector being disposed on the tank;
- an air conditioning case defining an air passage through which air flows into a passenger compartment of the vehicle, wherein:
- the evaporator is disposed in the air conditioning case to approximately cross an entire sectional area of the air passage;
- and
- the temperature detector is disposed between a tank surface of the tank of the evaporator and the air conditioning case in a direction perpendicular to a flow direction of air gassing through the evaporator.

- and
- a temperature detector for detecting a temperature of the evaporator, the temperature detector being disposed on the tank, wherein:
- the evaporator is constructed to be divided into at least two parts in a flow direction of air passing through the evaporator, and to be divided into at least two parts in a width direction approximately perpendicular to the flow direction of air;
- the tank has a first tank portion connected to a refrigerant inlet from which refrigerant flows into the evaporator, a second tank portion from which refrigerant is discharged to an outside of the evaporator to define a refrigerant flow direction, and a third tank portion disposed between the first tank portion and the second tank portion in the refrigerant flow direction;
- and
- the temperature sensor is disposed to contact the third tank portion.
