HOUSING STRUCTURE OF ELECTRIC DEVICE AND EXPLOSION-PROOF TYPE DEVICE

摘要

PROBLEM TO BE SOLVED: To effectively radiate heat generated by an electric device housed in a housing.SOLUTION: A camera module 20 equipped with a camera 21 is inserted into a body 11 of an explosion-proof container 10 through a front surface side opening part 11A in the body 11. The camera module 21 includes a holder 23 where the camera 21 is attached to an attachment part 23A through a plate 22, and a first heat radiation part 23B made of a heat conduction material is formed at a part of the holder 23. The first heat radiation part 23B makes surface contact with the interior of the body 11. Heat mainly generated by the camera 21 is conducted from the plate 22 to the first heat radiation part 23B via the attachment part 23A. Then, the heat is conducted to the body 11 to be efficiently radiated to the exterior.
