ABSTRACT:
A method and apparatus is described for cooling molten cones of glass drawn from a fiber glass manufacturing bushing for the purpose of removing heat from the cones of glass during formation. The heat removal means utilized involves flat, platelike fins or bars of metal connected to a common header through which heat transfer fluid is circulating. The platelike member has incorporated therein wick material on the interior, peripheral surfaces thereof. The wick contains a liquid therein which is vaporized rapidly during heat removal and condensed within the interior of the platelike members and redeposited on the wick for continuous circulation of fluid in the fin during operation. The wick material and the fluid associated therewith contained in the platelike member is sealed in the platelike member to prevent dissipation therefrom. Embodiments showing the utilization of configurations of fins other than the platelike member are described and a method of providing for a vertical temperature gradient below the bushing tips over a given distance are also described.
