Abstract (en)
A heat exchanger assembly is provided having at least one header, a plurality of spaced apart fluid tubes in hydraulic communication with the header, and a plurality of corrugated fins disposed between the tubes. The corrugated fins include a planar portion (154) having a louver segment (162) defined between a pair of primary slits (164), in which the louver segment (162) includes an intermediate slit (165) splitting the louver segment (162) into a pair of mini-louvers (176. 178). The mini-louvers (176, 178) are counter-offset such that one of the mini-louvers (176, 178) is on one side of the planar portion (154) and the other one of the mini-louvers (176, 178) is on the other side of the planar portion (154). The mini-louvers (176, 178) may be pivoted about their respective junctures such that each of the mini-louver (176, 178) is oblique relative to the planar portion (154).
