A multiple tube bank heat exchanger includes a first tube bank including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship and a second tube bank including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship. The second tube bank is disposed behind the first tube bank with a leading edge of the second tube bank spaced from a trailing edge of the first tube bank. A continuous folded fin extends between the first and second flattened tube segments of both of said first tube bank and said second tube bank.

Flattened tube finned heat exchanger and fabrication method

A method is disclosed for assembling a flattened tube multiple tube bank heat exchanger that includes a first tube bank and a second tube bank, each bank including a plurality tube segments extending longitudinally in spaced parallel relationship. A spacer clip is installed on a longitudinally extending edge of each heat exchange tube segment arrayed in a first layer of tube segments. A plurality of heat exchange tube segments are arrayed in a second layer in engagement with the spacer clips installed on the tube segments of the first layer.
