Abstract
The invention relates to a heat exchanger, constituted by a plurality of superposed units, each unit being constituted by a cylinder provided with outer fins and inner fins. The tightening of the units on one another effects a seal between a space inside the units and an outer space. Fluids circulate respectively inside and outside. The units are of sufficiently short dimension to allow an easy shaping of ribs and particularly of inner ribs. The invention is more particularly applied to the exchange of heat between two gaseous fluids.
Claims9
A heat exchanger which comprises a plurality of hollow cylindrical units, superposed contiguously on a common axis, said units having outer fins distributed on the outer periphery thereof and inner fins on the inner periphery thereof, said outer and inner fins extending outwardly and inwardly, respectively from said periphery in planes parallel to the direction of superposition of the cylindrical units and parallel to said common axis, the interior space defined by each of said hollow cylindrical units providing a first channel for circulation of a fluid along the longitudinal axis of the cylinders, and an envelope in which said cylindrical units are positioned, the inner wall of said envelope defining, with the outer wall of the superposed cylinders, a second channel for the circulation of a fluid along said axis.
The heat exchanger of claim 9, wherein the inner fins of each of said cylindrical units are constituted by ribs forming partitions in the space inside the cylinder.
