Abstract

Abstract A stacked plate heat exchanger (10) is disclosed which includes heat exchange plates (12,12') arranged in stacked relation, each of the plates including a peripheral flange. Each plate (12,12') includes two types of flow openings (20,22), one type (20) being formed as part of a depression therein, the other (22) being substantially coplanar with the plate surface. The flow openings (20) within the depressions adjoin the coplanar flow openings (22) of the plate positioned immediately therebelow. Additional projections (24) and depressions (28) are formed between the flow openings of each plate to support it against similar projections (24') and depressions (28') formed in adjacent plates. A turbulator (34) is positioned between and helps support each adjoining pair of heat exchange plates (12,12'). Fluid is introduced to the heat exchanger by means of a nozzle (52) having a base portion locked between a top plate (36) and one of the heat exchange plates (12,12').

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 240 words
A plate type heat exchanger comprising: a plurality of first heat exchange plates arranged in stacked relation, each of said first heat exchange plates including a heat transfer section, a peripheral flange extending downwardly from said heat transfer section, a first depression extending downwardly from said heat transfer section, said first depression including a first flow opening extending therethrough, a second flow opening defined within said heat transfer section, a first projection extending upwardly from said heat transfer section, and a second depression extending downwardly from said heat transfer section; a plurality of second heat exchange plates arranged in alternating, stacked relation with said first heat exchange plates, each of said second heat exchange plates including a heat transfer section, a peripheral flange extending downardly from said heat transfer section, a first depression extending downwardly from said heat transfer section, said first depression including a first flow opening extending therethrough, a second flow opening defined within said heat transfer section, a first projection extending upwardly from said heat transfer section, and a second depression extending downwardly from said heat transfer section; said first flow opening of at least one of said first heat exchange plates adjoining said second flow opening of at least one of said second heat exchange plates; and said first depression of said at least one of said first heat exchange plates adjoining said first projection of said at least one of said second heat exchange plates.
Claim 2
Dependent Claim 240 words
A plate type heat exchanger comprising: a plurality of first heat exchange plates arranged in stacked relation, each of said first heat exchange plates including a heat transfer section, a peripheral flange extending downwardly from said heat transfer section, a first depression extending downwardly from said heat transfer section, said first depression including a first flow opening extending therethrough, a second flow opening defined within said heat transfer section, a first projection extending upwardly from said heat transfer section, and a second depression extending downwardly from said heat transfer section; a plurality of second heat exchange plates arranged in alternating, stacked relation with said first heat exchange plates, each of said second heat exchange plates including a heat transfer section, a peripheral flange extending downardly from said heat transfer section, a first depression extending downwardly from said heat transfer section, said first depression including a first flow opening extending therethrough, a second flow opening defined within said heat transfer section, a first projection extending upwardly from said heat transfer section, and a second depression extending downwardly from said heat transfer section; said first flow opening of at least one of said first heat exchange plates adjoining said second flow opening of at least one of said second heat exchange plates; and said first depression of said at least one of said first heat exchange plates adjoining said first projection of said at least one of said second heat exchange plates.
Claim 3
Dependent Claim 41 words
A heat exchanger as defined in Claim 1 wherein each of said first heat exchange plates and said second heat exchange plates is substantially rectangular, and each includes a pair of opposing lateral sides and a pair of opposing longitudinal sides.
Claim 4
Dependent Claim 33 words
A heat exchanger as defined in Claim 2 wherein each of said first and second flow openings of said first heat exchange plates is positioned adjacent to one of the lateral sides thereof.
Claim 5
