However, in such a structure, dust contained in the air, sulfur dioxide gas and the like can be prevented from entering, but when installed in an atmosphere filled with steam or moisture of cutting oil,
A liquid such as oil or water condensed by the radiating fins may travel through the heat pipe and enter the closed casing through a gap between the partition plates. For this reason, there is a problem that the reliability of the electronic components and the like in the housing may be increased, and a leakage accident may occur. Further, there is a problem that the corrosion of the material used in each part significantly progresses due to the influence of moisture. Also, since the wiring lead wire 6 of the fan 31 on the outside air side is drawn into the sealed housing from the outside air side, there is a possibility that oil or water may enter through the wiring lead wire in the same manner as described above. There was a problem.
