<P>PROBLEM TO BE SOLVED: To provide a heat exchanger for an LPI vehicle that prevents internal pressure of a cylinder from increasing by causing LPG fuel to flow in the cylinder after decreasing the temperature of the LPG fuel by conducting mutual heat exchange between refrigerant that circulates in an air conditioning system and the LPG fuel returned to the cylinder from an engine. <P>SOLUTION: The heat exchanger for an LPI vehicle has a mechanism to cool high-temperature LPG fuel returned from the engine in an LPI vehicle that uses LPG fuel, and includes: a radiator in which a plurality of plates are stacked to form the first to third connection flow paths, first to third working fluids flow into first to third connection flow paths respectively, pass the first to third connection flow paths so that the mutual heat exchange is conducted, and the first to third working fluids supplied to the first to third connection flow paths respectively do not mix mutually and circulate; first to third inlets that are formed on one surface of the radiator, connected to the first to third connection flow paths respectively, and supply the first to third working fluids to the first to third connection paths respectively; and first to third outlets that are formed on the other surface of the radiator in correspondence with the first to third inlets respectively, connected to the first to third connection flow paths respectively, and discharge the first to third working fluids from the first to third connection flow paths respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
