Embodiment Construction

[0027] First, see the figure 1 and figure 2 , depicts an exemplary embodiment of a multi-bundle flattened tube-fin heat exchanger 10 according to the present invention. As depicted here, the heat exchanger comprises a first tube bank 100 and at least a second tube bank 200 arranged after the first tube bank 100 . Each of the first tube bundle 100 and the second tube bundle 200 includes a first manifold 102, 202 extending along a vertical axis and a second manifold 104, 204 also extending along a vertical axis. It should be appreciated that the multi-bundle flattened tube-fin heat exchanger 10 disclosed herein may include more than two tube bundles.

[0028] The first manifold 102 and the second manifold 104 of the first tube bundle 100 are spaced apart from each other, with a plurality of heat exchange tube sections 106 (which are at least a first tube section and a second tube section) in spaced parallel relationship in the first The manifold 102 extends longitudinally th...

Abstract

A multiple tube bank heat exchanger includes a first tube bank (100) including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship and a second tube bank (200) including at least a first and a second flattened tube segments extending longitudinally in spaced parallel relationship. The second tube bank (200) is disposed behind the first tube bank (100) with a leading edge of the second tube bank spaced from a trailing edge of the first tube bank. A continuous folded plate fin extends between the first and second flattened tube segments of both of said first tube bank and said second tube bank.

[0001] Cross References to Related Applications [0002] U.S. Provisional Application Serial No. 61 / 416,145, filed November 22, 2010, entitled "Multiple Tube Bank Flattened Tube Finned Heat Exchanger" and claims priority to it right and interest, the entire content of said application is incorporated herein by reference. field of invention [0003] The present invention relates generally to heat exchangers, and more particularly to flattened tube and fin heat exchangers. Background of the invention [0004] Heat exchangers have long been used as evaporators and condensers in heating, ventilation, air conditioning, and refrigeration (HVACR) applications. Historically, these heat exchangers have been round tube and plate fin (RTPF) heat exchangers. However, flattened tube-sheet-fin heat exchangers are increasingly used in industry, including the HVACR industry, due to their compactness, structural rigidity, lower weight and Lower refrigerant costs required.
