Problems solved by technology

[0007] However, in the case of this vehicle air conditioner, since the low-temperature outside air is heated by the heater core and then blown out from the defroster opening to the front windshield, a large amount of thermal energy is required for heating. (energy), so that the dehumidification of the indoor air by the air conditioner cannot be carried out

Abstract

To provide an air conditioner for a vehicle includes an evaporator, a heater core, an air conditioning passage, an inside air introduction passage, an outside air introduction passage, and a heat pipe. In the air conditioning passage, a ventilation portion of the heater core is disposed downstream from a ventilation portion of the evaporator. Through the heat pipe, heat is transferred from a hightemperature portion on the inside air introduction passage side to a low temperature portion on the outside air introduction passage side due to evaporation and condensation of a refrigerant. The heatpipe is provided in the evaporator to straddle a position facing the inside air introduction passage and a position facing the outside air introduction passage.

Description

technical field [0001] The present invention relates to a vehicle air conditioner equipped with a dehumidification function. Background technique [0002] Most vehicle air conditioners are equipped with: an evaporator, which absorbs heat from the conditioned air through a refrigeration cycle; (heater) etc. to heat the air-conditioned air. Such an air conditioner for a vehicle can appropriately control the temperature and humidity in the vehicle compartment by combining heat absorption by the evaporator and heating by the heater core. [0003] However, when the heating operation is performed in cold weather, the inside of the front glass (front glass) may be fogged due to water vapor exhaled from the occupant or moisture carried in clothing or the like in the vehicle cabin. In this case, by blowing dehumidified and heated air from an opening of a defroster of the vehicle air conditioner, it is possible to remove frost on the windshield. [0004] However, when the temperatu...
