Abstract

A method and apparatus for separately supporting and sealing a heat pipe within a heat exchanger. For support, the heat pipe with fins thereon passes through a support grid which consists of a series of rings secured or interconnected together. The fins of the heat pipe rest upon these rings of the support grid thereby supporting this region of the heat pipe. To seal these heat pipes in order to prevent any gas escape from the heat exchanger, a tubesheet with openings therein is placed over the ends of the heat pipe. These openings are oversized thus a considerable gap exists between the tubesheet and the heat pipe. This gap is covered or sealed by use of a cover disk which tightly fits around the heat pipe and spans across this gap before it is removably secured to the tubesheet. By this fashion, once the cover disk is removed from the tubesheet, it is a relatively easy task to then remove the tubesheet and the heat pipe from the heat exchanger for maintenance or repair purposes.
