HEAT EXCHANGER IN PARTICULAR FOR SOLAR APPLICATIONS, WITH IMPROVED DESIGN

摘要

Heat exchanger in particular for solar heat applications. The heat exchanger is composed of one or more, preferably plate-like, flat elements (2) each with one or more integrated tubes (3) with channels (13) for a heat exchanging fluid. The elements (2) are each at their respective ends interconnected by means of inlet, respectively outlet manifolds, or manifold tubes (4). Each of the ends of the plate-like element (2) with the integral tube (3) is formed by cutting alongside the integral tube (3) making recesses (6) on each side of the tube (3) and notches (7) forming two or more tabs (8, 9) stretching beyond the tube (3) and which are bent and formed such that the resulting, projecting shape (10), conform closely to the outside profile of the manifold tube (4) making the solution self-jigging, easy to assemble and with accuracy and high performance.
