Method and apparatus for reducing thermal fatigue in heat excharger core

摘要

A heat exchanger (10) uses a skeleton forming of a lattice of first and second bars (36, 38) to provide a box-like structure. Blocking bars (44) are arranged between gaps (42) in the first and second bars (36, 38) to provide a blocking surface to divert airflow around a portion of the heat exchanger core (12). A brazing material (46) is used in the assembly of the core (12) and the skeleton, which includes the blocking bars (44).
