Abstract

1472551 Heat exchanger fins VARIAN ASSOCIATES 11 Nov 1974 [12 Nov 1973] 48785/74 Heading F4S [Also in Division H1] Heat transfer fins 13 extend generally radially outwardly and longitudinally in arcuate array from a device 11 such as the anode assembly of an electron beam tube, klystron, or travelling wave tube, to be cooled by an air stream flowing over the fins, each fin being corrugated into a wave-like geometry in which the corrugations increase in amplitude as their distance from the longitudinal axis of the device 11 increases, and the air flow being confined to the fin assembly by a cylindrical baffle 17. The corrugations may be sinuous as shown in Fig. 1 or angular as shown in Fig. 3. The fins may be entirely radially directed (as shown) or they may be of involute shape. The arrangement is said to provide a vortex action of the cooling air near the outer surface of the device 11 as shown by the arrows in Fig. 1. The fins, which may be perforated, are preferably of copper of aluminium, each fin being brazed into a corresponding groove 14 in the surface of the device 11.
