Abstract
1,224,298. Heat pipes. EUROPEAN ATOMIC ENERGY COMMUNITY (Euratom). 19 Nov., 1969 [5 Dec., 1968], No. 56688/69. Heading F4U. A heat pipe whose heat carrier is in the solid state at start up is partially bridged by at least one auxiliary heat pipe to increase the initial transmission of heat along the main pipe. The auxiliary heat pipe(s) may be formed in the wall of the main pipe, may be secured internally or externally to the wall of the main pipe, or may be located along the axis of the main pipe so as to heat the wall of the latter by radiation. A plurality of auxiliary heat pipes may be thermally connected in series, and each pipe of the series may be thermally connected either at its ends or over its whole length to the main pipe. A second series of auxiliary pipes may be staggered with respect to the first series so as to bridge the joints between the pipes of the first series. If it is undesirable to heat the main pipe above the melting temperature of its heat carrier, the auxiliary pipe(s) will be arranged along the axis of the main pipe or on fins extending externally from the wall of the main pipe.
