Although it is heated and supplied, baffle plates are provided between the heat transfer fins of the air cooler and before and after the heat transfer fins so that the air flow passes through the air cooler in a meandering direction. Then, even if the front-back width of the support frame or the front-back width of the air cooler is narrowed, the cooling capacity of the air is maintained, so that the installation area can be further reduced. In addition, the support frame, such as a square pipe-shaped steel material with a rectangular cross section, guarantees the support strength,
In addition, any material may be used as long as it can form the left and right side surfaces of the chamber. Needless to say, publicly known means may be appropriately used for fixing the air cooler, the electric heater, the top plate, the side plate, and the like fixed to the frame to the frame. For example, the air cooler may be fixed to the sleeve portions 2a, 3a of the frame via appropriate mounting pieces provided on the left and right side plates of the air cooler, instead of hanging from the top plate portion.
