Title:
PORTABLE HEAT RADIATION MEASURING DEVICE AND HEAT DIAGNOSIS METHOD
Document Type and Number:
Japanese Patent JP2023110473
Kind Code:
A
Abstract:
To provide a portable heat radiation measuring device and a heat diagnosis method having increased accuracy.SOLUTION: A portable heat radiation measuring device including a cylindrical roller surface part 20 provided rotatably around a rotating shaft 10, and a heat radiation sensor 50 for measuring heat radiation from an inner surface of the roller surface part is used. A heat diagnosis method includes: a first heat conduction process of bringing an outer surface 41 of a first part 21 of a roller surface part into contact with a first part of a target surface, and performing heat conduction of the first part of the roller surface part and the first part of the target surface; a first measurement process of measuring heat radiation from an inner surface of the first part of the roller surface part by the heat radiation sensor; a second heat conduction process of rotating the roller surface part around the rotating shaft, bringing an outer surface 42 of a second part 22 adjacent to the first part of the roller surface part into contact with a second part adjacent to a first part of a target surface, and performing heat conduction of the second part of the roller surface part and the second part of the target surface; and a second measurement process of measuring heat radiation from an inner surface of the second part of the roller surface part by a heat radiation sensor.SELECTED DRAWING: Figure 4B
