Abstract: Disclosed is an air conditioner for a vehicle, the air conditioner having an improved guide structure capable of increasing an air volume by preventing a collision between air flowing through an upper passage and air flowing through a lower passage. The air conditioner for a vehicle comprises: an air conditioning case having an air passage formed therein and an air outlet which includes a defrost vent and a face vent; and a heat exchanger for cooling and a heat exchanger for heating, which are provided in the air passage of the air conditioning case. The air conditioner for the vehicle further comprises: a temperature door arranged between the heat exchanger for cooling and the heat exchanger for heating in order to adjust the degree to which cold air, which has passed through the heat exchanger for cooling, is heated by the heat exchanger for heating; a cold air passage through which cold air that has passed through the heat exchanger for cooling bypasses the heat exchanger for heating; a warm air passage through which cold air that has passed through the heat exchanger for cooling passes through the heat exchanger for heating; a cold air guide unit for guiding the cold air downstream of the heat exchanger for cooling; and a warm air guide unit for guiding the warm air downstream of the heat exchanger for heating.

Abstract: The present invention relates to an air conditioner for a vehicle which can block air introduced through a gap between an evaporator and an air-conditioning case and prevent condensate from overflowing toward a temperature adjusting door when condensate exceeding a drainable amount is generated. The air conditioner for a vehicle includes: an air-conditioning case having an air passageway therein; an evaporator disposed in the air passageway of the air-conditioning case; a drain hole disposed at the downstream side of the evaporator in an air flow direction to discharge condensate to the outside; a first baffle protruding upwardly from the bottom surface of the air-conditioning case; and a fourth baffle protruding upwardly from the bottom surface of the air-conditioning case and formed downstream of the first baffle in the air flow direction, wherein the first baffle and the fourth baffle are formed in such a way that at least some of them are overlapped with each other in the width direction to be formed doubly in the air flow direction.

Abstract: Disclosed is a heat exchanger capable of exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind from the first coolant flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.
