摘要
The present invention relates to an internal heat exchanger double-tube structure of an air conditioning system having an alternative refrigerant applied thereto for heat exchange between a low-temperature low-pressure refrigerant discharged from an evaporator and a high-temperature high-pressure refrigerant discharged from an condenser, the double-tube structure including: an inner pipe having a channel through which the low-temperature low-pressure refrigerant discharged from the evaporator flows; and an outer pipe surrounding the inner pipe and having a channel through which high-temperature high-pressure refrigerant flows, wherein the inner pipe has a spiral groove forming a channel on an outer side thereof, and the spiral groove is a recessed groove for generating a vortex that increase a channel volume where high-temperature high-pressure liquid flows inward and reduces a vortex of flowing fluid.
