Abstract (en)

[origin: EP2336701A2] The assembly includes a heat exchanger assembly (20) including a plurality of tubes (32) extending between first and second manifolds. A plurality of fins (42) extend back and forth between and long the tubes (32) in a continuous patch and define a plurality of legs (48) extending between the tubes (32). Each of the legs (48) includes a plurality of front long louvers (52) for conveying a stream of air through the legs. Each of the legs further defines a plurality of main spoilers (56) between the front long louvers (52) and the back edges (44,46) of the legs (48) for inducing turbulence in the stream of air with each of the main spoilers (56) having a spoiler height in the range of 50 to 90 percent of the long louver height and each of the main spoilers (56) having a spoiler length in the range of 10 to 35 percent of the long louver length.
