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.Claims:
1. (canceled)
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.
Description:
FIELD OF THE INVENTION
[0001] The present inventions relates to a heat exchanger element of large surface.
BACKGROUND OF THE INVENTION
[0002] The heat exchangers that operate with internal pressure, for example in water tube boilers, generally includes tubes of various shapes and in such amounts as to provide the area required to exchange the amount heat that is intended. In these equipment the of heat exchange is directly proportional to the number of tubes of the same diameter, carrying a linear relationship between the size and the ability of heat exchange.
SUMMARY OF THE INVENTION
[0003] The objective of the present invention is to provide an element of heat exchanger of large surface, replacing sets of pipes, in such a way to enable the construction of more compact heat exchangers providing a larger exchanging area per furnace volume.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] The FIGURE shows a heat exchanger element according to an embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0005] Referring to the drawing:--two metal plates 1 and 2 having half spheroidal cavities 3 and polygonal bases 4. The polygonal base having any suitable number of sides, as for example, square or pentagonal.
[0006] The two plates 1 and 2 are specularly juxtaposed in such a way that the half spheroidal cavities 3 conform a interconnected polyspherical space 5.
[0007] Plates 1 and 2 when juxtaposed are fastened together at the contact points 6 of the polygonal bases by any suitable fastening elements 7 such as welding, rivets, screws, etc, as well the plates edges 8, making pressure tight the so created polispherical space.
[0008] Input pipe 8 and output pipe 9 allow the circulation of the fluid to heat or cool.
[0009] This constructive layout behaves, when subjected to internal or external pressure similar to the way several interconnected spherical vessels behave, providing a large surface pressure resistant element.
