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 30 and a third row of tubing 50 sandwiching a second row of tubing 40. The second row of tubing 40 terminates in opposite ends 42,44 on which are received refrigerant fittings 46 and 48 respectively. The first and third rows of tubing 30, 50 each include a run abutting and in heat exchange relation with the tubing 40. Opposing ends 32, 34 of the tubing 30 extend about refrigerant fittings 46 and 48 and are received in refrigerant fittings 36, 38. The tubing 50 includes parts 52 and 54 extending about the refrigerant fittings 46 and 48 and terminating in opposite ends 56, 58. The ends 56, 58 are also in fluid communication with fittings 36, 38.
