SUCTION FLOW ENHANCEMENT FOR INTERNAL HEAT EXCHANGER

摘要

An internal heat exchanger includes an inner tube for a flow of a first fluid; an outer tube that is coaxial with the inner tube; a passageway between the inner tube and the outer tube for a flow of a second fluid; and, a flow enhancer inside the inner tube and configured to divert the flow of fluid in the inner tube along a wall of the inner tube.
