Heat exchanger element of large surface

Abstract

Large surface heat exchanger element composed of two metal plates provided with half spheroidal cavities, juxtaposed and united as to conform a sealed space in such way that the so conformed space provides resistance to internal or external pressure similar to a set of interconnected spherical wessels.

         2 . A heat exchanger element of large surface comprising:
 a first plate having a polygonal shape, spheroid cavities, and edges;   a second plate having a polygonal shape, spheroid cavities, and edges, the first plate is juxtaposed with the second plate forming a polyspherical space between the plates;   a first set of fasteners to connect the plates at a contact point on the respective polygonal bases;   a second set of fasteners to seal the plates at the edges forming a sealed space between the plates;   an input pipe located on a first side of the polyspherical space; and   an output pipe located on a second side of the polyspherical space.
