ABSTRACT:
A stacked plate heat exchanger is disclosed which includes heat exchange plates arranged in stacked relation, each of the plates including a peripheral flange. Each plate includes two types of flow openings, one type being formed as part of a depression therein, the other being substantially coplanar with the plate surface. The flow openings within the depressions adjoin the coplanar flow openings of the plate positioned immediately therebelow. Additional projections and depressions are formed between the flow openings of each plate to support it against similar projections and depressions formed in adjacent plates. A turbulator is positioned between and helps support each adjoining pair of heat exchange plates. Fluid is introduced to the heat exchanger by means of a nozzle having a base portion locked between a top plate and one of the heat exchange plates.
