Abstract

1,044,952. Finned heat exchange elements. COMMISSARIAT A L' ENERGIEATOMIQUE. July 10, 1963 [July 24, 1962], No. 27320/63. Heading F4S. - [Also in Division G4-G6] A heat exchanger comprises fins arranged with respect to the direction of flow of cooling fluid in chevron pattern, spirally, polyzonally or transversely with induced flow, the subchannels between the fins being distributed regularly in successive similar groups, successive sub-channels in a group being alternately larger and smaller in depth and/or width than the preceding sub-channel. In one embodiment (Fig. 4, not shown), a sheath 4 is provided with fins 5, 6 arranged in a chevron pattern with intermediate longitudinal passages 7, 8 devoid of fins. The sub-channels are alternately deep (sub-channels 10, 11) and less deep (sub-channels 12, 13). In an alternative arrangement (Fig. 3, not shown), the fins are alternately wide (2a) and narrow (2b) and the sub-channels alternately wide and deep (3a) and narrow and less deep (3b). The fins may be of rectangular or trapezoidal section and the bases of the sub-channels may be flat, concave or convex. With such fin arrangements, particularly in the application to a nuclear reactor fuel element, there is a decrease in the bending movement and in the temperature at the base of the fins compared with conventional fin arrangements, enabling a metal possessing better neutronic qualities but poorer mechanical characteristics to be used and for the temperature at the base of the fins to be increased to obtain an improved output from the reactor.
