Abstract:

A heat exchanger provides simplicity, compactness, and high efficiency through a construction that includes an elongated tube structure comprising three rows of flattened multiport tubing, with a first row of tubing and a third row of tubing sandwiching a second row of tubing. The second row of tubing terminates in opposite ends on which are received refrigerant fittings and respectively. The first and third rows of tubing each include a run abutting and in heat exchange relation with the tubing. Opposing ends of the tubing extend about refrigerant fittings and and are received in refrigerant fittings. The tubing includes parts and extending about the refrigerant fittings and and terminating in opposite ends. The ends are also in fluid communication with fittings.
