A microtube-strip module, consisting of a plurality of parallel rows of microtubes, metallurgically bonded to rectangular header tubestrips, is encapsulated in solid metal in such a way as to leave at least one major surface exposed in a manner suitable for metallurgical bonding to an objective surface requiring heat transfer. Fluid connections are provided perpendicular to the objective surface to facilitate parallel manifolding of a plurality of these modules with high surface coverage. The device is intended for ultra high thermal flux applications, especially in aerospace and in controlled thermonuclear fusion, for the efficient transfer of heat between an objective surface and a working fluid, especially high pressure helium gas.
