Integrated plate-type heat exchanger

Abstract

An integrated plate-type heat exchanger includes: a condenser configured to condense refrigerant by heat exchange between first coolant and the refrigerant; a chiller configured to cool second coolant by heat exchange between the refrigerant passing through the condenser and the second coolant; an internal heat exchanger configured to facilitate heat exchange between the refrigerant coming from the condenser and the refrigerant coming from the chiller; an expansion valve configured to expand the refrigerant discharged from the internal heat exchanger; a connecting plate unit positioned between the internal heat exchanger and the chiller to form a flow path for the refrigerant; and one or more refrigerant outlets to discharge the refrigerant from the connecting plate unit. The connecting plate unit comprises first and second connecting plates positioned to adhere to each other. The first and second connecting plates include one or more through holes for movements of the refrigerant between the internal heat exchanger, the chiller, the expansion valve, and the refrigerant discharge port, and one or more refrigerant spaces for movement of the refrigerant between the first and second connecting plates.
