发明名称 HEAT EXCHANGER WITH PARALLEL FLOWING FLUIDS
摘要 A heat exchanger is disclosed using a plurality of stacked plate pairs consisting of face-to-face mating plates with each plate having a peripheral flange and annular inner and outer primary bosses. Each boss has a portion thereof located in a common first plane with the peripheral flange. An annul ar secondary boss has a portion thereof located in a second plane spaced from t he first plane. Intermediate areas between the inner and outer primary bosses have spaced-apart portions to form inner flow passages. Both the primary and secondary bosses have openings formed therein for the passage of heat exchanging fluids. In back-to-back plate pairs, the secondary bosses are joined and the openings therein communicate to define a manifold for a second of these fluids. The inner and outer primary bosses include radially extending ribs formed about the circumference of each boss and extending substantially acro ss the boss. These ribs are located between the openings formed in the boss and form cross-over passages that permit the second fluid to flow across the primary bosses and through the inner flow passage. There are also rectangula r versions of the heat exchanger having at least first and second elongate primary ridges and at least one elongate secondary ridge.
