PROBLEM TO BE SOLVED: To provide an air-cooling mechanism which is arranged in a housing and contributes to prolongation of a service life of a filter by removing iron power in the ambient air before passing the filter in the air-cooling mechanism arranged in the housing.SOLUTION: A housing 2 includes: a display device 3 mounted on a front opening and closing lid 4; a base 6 in which an electronic component 7 is mounted on an inner back face; an exhaust fan 8 and support pipes 5a, 5b arranged on a ceiling part upper surface 2-1; a coil unit 14 arranged on a lower part opening 9; and a filter 15 arranged above the coil unit. The coil unit 14 includes: a lower holding plate 11 having a plurality of holding part suction ports 16; an upper holding plate 12 having a plurality of holding part exhaust ports 17; cylindrical bodies 13 whose air passage suction ports are connected to the holding part suction ports 16 and whose air passage exhaust ports are connected to the holding part exhaust ports 17 to form air passages of the ambient air; and coils 23 which are wound around the outer peripheral surfaces of the cylindrical bodies 13 and in which electric conduction and shutdown can be performed. |
