Abstract
Improved resistance to pressure caused deformation in header and tank construction utilized in heat exchangers is achieved by providing domes, preferably exteriorally convex, in the header surfaces of the header and tank construction. These domes are located in the area between the holes in such constructions through which tubes extend.
Claims2
A heat exchanger comprising:
- spaced generally parallel header and tank constructions;
- each of said header and tank constructions having elongated, spaced, tube receiving holes in a header surface thereof;
- the holes in one header surface being aligned with and facing corresponding holes in the other header surface;
- and
- elongated open ended, flattened tubes extending between and into said header and tank constructions through aligned ones of said holes;
- the portions of each header surface between said holes including exteriorly convex domes defined by compound curves to thereby provide increased resistance to deformation as a result of force exerted by a pressurized fluid within said header and tank construction.
