ABSTRACT:
A three row condenser for cooling alternative refrigerants for use in automotive air conditioning systems has a continuously formed U-bend tube forming the air inlet to the condenser at a point upstream of second and third rows of like tubes each interconnected by parallel heat conducting cooling fins; the high pressure vapor inlet flow to the condenser is substantially equally distributed into the first, second and third rows and refrigerant flow in the first and second rows of tubes is combined upstream of the outlet of the condenser to provide a series connected tube pattern for increasing the flow velocity through outlet portions of the first and second rows of tubes so as to improve the efficiency of energy transfer between the refrigerant flow through the condenser and the air flow across the air fins therein.
