PLATE-TYPE HEAT EXCHANGER AND AIR CONDITIONING SYSTEM FOR VEHICLE HAVING THE SAME

A plate-type heat exchanger including a body plate, an upper plate, and a lower plate. The body plate includes a plurality of alternately stacked plates, a space between the plurality of plates having a first heat exchange passage through which a first refrigerant of high temperature and high pressure flows, and a second heat exchange passage through which a second refrigerant of low temperature and low pressure flows. A heat exchange between the first refrigerant and the second refrigerant is performed in the body plate. The upper plate is bonded to a front side of the body plate and having a first inlet hole through which the first refrigerant is introduced and a first outlet hole through which the second refrigerant is discharged. The lower plate is bonded to a rear side of the body plate and having a second inlet hole through which the second refrigerant is introduced and a second outlet hole through which the first refrigerant is discharged.
