ABSTRACT:
A cooling device provided in a thermal analyzer to cool a heating furnace by heat exchange between a cooling medium and the heating furnace based on direct and uniform gas-to-solid contact, and constructed to facilitate replacement of a sample in the cooled furnace. The cooling device includes a jacket surrounding the heating furnace to define a closed annular space, an inlet formed to introduce cooling medium into the closed space, and an outlet formed to discharge the introduced cooling medium from the closed space. Cooling of the furnace is carried out due to the heat exchange between the cooling medium and the heating surface in the closed space. A top portion of the heating furnace is not covered by the jacket, but is exposed to thereby facilitate the replacement of a sample through the exposed top portion of the heating furnace.
