Abstract
A vacuum oven with heat transfer fluid conduits. The oven of the invention generally includes a shell into which a removable rack may be placed. The rack has at least one plate which may be heated or cooled by a plate fluid conduit in contact with the plate and through which a heating or cooling fluid may be passed. Work pieces may be loaded in the rack, the rack placed in the shell, the shell sealed, and a vacuum drawn within the shell. The work pieces loaded on the rack are primarily heated and cooled by conductive and radiant heat transfer because of the limited amount of thermally conductive gases within the shell.
