COOLING DEVICE
Document Type and Number:
Japanese Patent JP2022114153
Kind Code:
A
Abstract:
To provide a cooling device that can efficiently cool a high-temperature cylindrical workpiece.SOLUTION: A cooling device 9 according to the present invention that cools a workpiece by bringing a pair of relatively low-temperature heat receiving blocks 11 and 12 into contact with the outer peripheral surface of a relatively high-temperature cylindrical workpiece 7 includes a pair of heat receiving blocks 11 and 12 and a pair of drive mechanisms 31 and 32. The pair of heat receiving blocks 11 and 12 are opposed to each other in the movement direction orthogonal to the axis of the workpiece 7, and have a plurality of heat receiving portions H capable of contacting the outer peripheral surface of the workpiece 7, and the plurality of heat receiving portions have a semi-cylindrical shape as a whole. The pair of drive mechanisms 31 and 32 reciprocate the pair of heat receiving blocks 11 and 12 between a contact position in contact with the workpiece 7 and a spaced position away from the workpiece 7. Each of the heat receiving blocks 11 and 12 has a plurality of heat-receiving fins, the tips of the heat-receiving fins are respectively the heat receiving portions 11 and 12, and the heat-receiving fins are separated from each other by slits.SELECTED DRAWING: Figure 1
