Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
For use in a heat exchanger, means for disposing a first fluid to have heat exchange with a second fluid, comprising: a continuous, integral, formed sheet of heat exchange material having a first area, a second area spaced therefrom to provide a laterally bounded fluid flow space therebetween having inlet and outlet ends, and a third area in said flow space between said first and second areas having a first side portion contiguous with said first area and an opposite side portion contiguous with said second area, means providing displaced turbulence producing portions of said sheet at said third area in said flow space, and means adjacent said ends joinIng said first and second areas in fluid confining relationship enclosing said third area for causing said sheet to define an enclosed fluid passage between said inlet and outlet ends for conducting a first fluid to have heat transfer association with a second fluid through said formed sheet.
Claim 2
Dependent Claim
157 words
For use in a heat exchanger, means for disposing a first fluid to have heat exchange with a second fluid, comprising: a continuous, integral, formed sheet of heat exchange material having a first area, a second area spaced therefrom to provide a laterally bounded fluid flow space therebetween having inlet and outlet ends, and a third area in said flow space between said first and second areas having a first side portion contiguous with said first area and an opposite side portion contiguous with said second area, means providing displaced turbulence producing portions of said sheet at said third area in said flow space, and means adjacent said ends joinIng said first and second areas in fluid confining relationship enclosing said third area for causing said sheet to define an enclosed fluid passage between said inlet and outlet ends for conducting a first fluid to have heat transfer association with a second fluid through said formed sheet.
Claim 3
Dependent Claim
37 words
The heat exchanger of claim 1 wherein there are provided a plurality of said displaced portions on opposite sides of said third area, some of said portions engaging said first area and others engaging said second area.
Claim 4
Dependent Claim
21 words
The heat exchanger of claim 2 wherein said displaced portions comprise projections having flat peaks engaging said first and second areas.
Claim 5
Dependent Claim
34 words
The heat exchanger of claim 1 wherein said means joining said first and second areas comprise flange areas on said formed sheet engaging adjacent portions of said sheet to enclose substantially said third area.
Claim 6
Dependent Claim
25 words
The heat exchanger of claim 1 wherein said heat exchanger is substantially tubular with said first, second and third areas being substantially concentric cylindrical sections.
Claim 7
Dependent Claim
52 words
The heat exchanger of claim 5 wherein there are provided a plurality of said displaced portions on opposite sides of said third area, some of said portions engaging said first area and others engaging said second area, and said displaced portions comprise projections having flat peaks engaging said first and second areas.
Claim 8
Dependent Claim
34 words
The heat exchanger of claim 6 wherein said means joining said first and second areas comprise flange areas on said formed sheet engaging adjacent portions of said sheet to enclose substantially said third area.
