The objective of the present invention is to provide a cooling device that is capable of uniform cooling of an article to be processed inserted into a cooling process chamber provided to a continuous sintering furnace. To achieve the objective, a cooling device is adopted that is provided to a continuous furnace that conveys, by means of a plurality of rollers provided in parallel, a plurality of workpieces loaded on a carrying tool stacked in a plurality of stages, and successively subjects the workpieces to a heating process and a cooling processs, wherein the cooling device is provided with: a cooling device that can, in the state of housing the plurality of workpieces, seal/enclose the plurality of workpieces subjected to the heating process; a decompressing device that decompresses the cooling device; a cooling fan that circulates a cooling gas within the cooling device and can adjust the circulation speed thereof; a heat exchanger for cooling the cooling gas; and a graphite sheet that is disposed in a manner so as to enclose the plurality of workpieces within the cooling device. |
