PURPOSE:To uniform the distribution of the quantities of a cooling air in each pipe by a mechanism wherein perforated plates for adjusting the quantity of a wind are mounted to portions bending in the airway direction of an internal ventilation flue in a ventilating duct in parallel with the discharge direction of the outside air for cooling. CONSTITUTION:A perforated plate 11 for adjusting the quantity of a wind is mounted to a portion bending in the airway 2 direction of a ventilation flue 9 between a parting plate 7 and a side plate 2a of an airway in parallel with the discharge direction of the outside air for cooling. A perforated plate 12 for adjusting the quantity of the air is installed to a portion bending in the airway 2 direction of a ventilation flue 8 between an outside plate 10 of a ventilating duct and the side plate 2a of the airway in parallel with the discharge direction of the outside air for cooling. Thus, the quantities of a cooling wind passing through plural pipes 3 mounted to the airway 2 are equalized, and cooling efficiency can be improved. |
