Abstract
A vacuum oven or vacuum furnace is disclosed having a heat distribution sleeve that conforms to the shape of an interior heating chamber. The heat distribution sleeve may be of generally annular shape, like a ring, and located in a substantially regularly spaced and offset relationship from a heating element located within walls adjacent the interior heating chamber. The heat distribution sleeve includes a thermal conductive material which absorbs and re-radiates heat emitted from the heating element, thereby providing more consistent and regular radiation fields for heating treating a work piece that is loaded on a work holding tray and, upon the vacuum oven being in an operational position, the work piece is located within the furnace chamber.
