ABSTRACT:
A heat exchanger uses a skeleton forming of a lattice of first and second bars to provide a box-like structure. Blocking bars are arranged between gaps in the first and second bars to provide a blocking surface to divert airflow around a portion of the heat exchanger core. A brazing material is used in the assembly of the core and the skeleton, which includes the blocking bars.
