Document Type and Number:
Japanese Patent JP2006509637
Kind Code:
A
Abstract:
The cross section of the single extended piece is shaped like a fish spine, with oblique hollow fishbones (12-14), forming parallel symmetrical pairs from a common central channel (16). The internal thickness of the fishbones is very small, as is the space between them and the thickness of the central channel. Each symmetrical pair of longitudinal fishbones forms one modular pipe of the piece The common central channel is in all the planes of symmetry of the stack of longitudinal fishbones in the piece. These symmetrical pairs contain rectilinear central elements to connect the ends together by two hollow connectors each formed from two returnable surfaces. The axes of the stack of connectors are the same as those for the two feed collectors for each modular pipe and one end of each collector ends by one of the two connection pipes of the piece. Outline of a modular heat exchanger as described above, with a stack of biconvex vents like an accordeon. Multiple exchanger modules can be installed in an envelope made of two half-shells which completely enclose the enchangers whilst controlling the spaces between them. Each half-shell encloses a longitudinal half of an exchanger or the assembly of several exchangers and has a half-tube connector at each end. The edges of the half-shells are welded together and the half-connectors are welded to the connections of the exchanger(s). ALSO CLAIMED is a mould for fabricating the rough exchanger and a method for fabricating the exchanger, as well as a method for fabricating the rough exchanger in metal and a method for finishing it, together with a machine-tool making the exchanger from a mould.
