An evaporator for a capillary pumped loop, has a a tubular wick for containing coolant liquid centrally therein, the body of the wick being saturated with the liquid coolant b a tubular heat exchanger for receiving said wick and c one or more longitudinal vapor channels between said wick and said heat exchanger, for transporting a vapor of the working liquid out of the evaporator where this tubular wick comprises a porous organicinorganic composite made by the sol-gel process. By replacing the conventional polyethylene wick with the composite wick, smaller pores, greater porosity, greater thermal stability, and other advantages are secured.
