| 摘要 |
The invention concerns an elementary heat exchanger comprising a single elongated active monobloc component (10), enclosed in a casing provided with coolant inlet and outlet. The casing consists of two half-shells (11a-b), welded together (98a-b, 114a--b), fixed to the active component. The active component (10) comprises a fishbone cross-section (10a-b), whereof the bones (12a-b) are hollow, oblique, embossed and globally symmetrical. The active component is made from a blank made of resistant material (for example a polymer), in the form of biconvex stiff-walled bellows (33--35-37-39), comparable to those of an accordion whereof the peaks have been struck off (36), narrow bases (38) and a spacing (16) between said bases. |
