Title:
Infrared heating equipment and a drying furnace
Document Type and Number:
Japanese Patent JP6225117
Kind Code:
B2
Abstract:
When electromagnetic radiation including infrared radiation is emitted from a filament 41, the infrared radiation passes through the inner pipe 42, reaches a reflection layer 46 that is disposed away from the inner pipe 42 so as to cover only a part of a periphery of the filament 41, and is reflected. At this time, the reflection layer 46 is disposed away from the inner pipe 42, and the reflection layer 46 can be cooled by a coolant flowing through a coolant channel 49. Thus, for example, as compared with a case where the reflection layer 46 is formed on the inner pipe 42, overheating of the reflection layer 46 can be further suppressed. A first outer pipe 44, which transmits infrared radiation, is disposed between the inner pipe 42 and the reflection layer 46. Thus, two layers, which are the inner pipe 42 and the first outer pipe 44, are present between the filament 41 and the reflection layer 46. Accordingly, overheating of the reflection layer 46 can be further suppressed.
