NOVELTY - A heat pipe wick is manufactured by positioning metal felt to a metal substrate (5); positioning a metal exoskeleton (20) to the metal felt; applying brazing material between the metal felt and metal substrate, between the metal felt and the porous metal exoskeleton or between the metal felt and metal substrate as well as between the metal felt and the porous exoskeleton; grit blasting elements from metal substrate and/or the porous metal exoskeleton; and applying heat to cause the metal felt to adhere to the porous metal exoskeleton and the metal substrate.    USE - For manufacture of heat pipe wick used in dish Stirling solar engines, in powdered metallurgy or woven wire screens.    ADVANTAGE - The invented method provides a good flow path for working fluid while maintaining durability and structural stability independent of the structure associated with wick material (10). The resulting heat pipe wick exhibits high porosity and permeability and is durable and can withstand, over the long term, mechanical loads and stresses encountered during normal operation.    DETAILED DESCRIPTION - Manufacture of a heat pipe wick involves positioning metal felt adjacent to a metal substrate; positioning a porous metal exoskeleton adjacent to the metal felt between the metal substrate and the porous metal exoskeleton; applying brazing material between the metal felt and metal substrate, between the metal felt and the porous metal exoskeleton or between the metal felt and metal substrate; grit blasting elements from metal substrate and/or the porous metal exoskeleton; and applying heat to cause the metal felt to adhere to the porous metal exoskeleton and the metal substrate. A temperature of 1100degreesC is attained by the metal felt, the metal substrate, and the porous metal exoskeleton during the application of heat.
