Abstract

A heat exchanger has a first flow path communicating fluid into a turning flow path at a first mitered interface. The turning flow path has a second mitered interface for communicating fluid from the turning flow path into a return flow path. The first flow path extends in a nominal direction toward the turning flow path. First flow passages within the first flow path and return flow passages in the return flow path are provided by walls having alternating sections which extend in opposed angular directions relative to nominal directions. Sizes of a portion of passages at the interfaces are different such that some passages are larger than other openings into other passages.

First claim

The invention claimed is:

1. A heat exchanger comprising:
a first flow path for communicating fluid into a turning flow path at a first mitered interface, said turning path having a second mitered interface for communicating fluid from said turning flow path into a return flow path;
the return flow path extends in a nominal direction away from the turning flow path, said first flow path extends in a first nominal direction toward said turning flow path, first flow passages withi…
