Girder steel cooling device

The utility model discloses a girder steel cooling device, including aluminum plate, aluminum plate is the U -shaped form, and the aluminum plate parcel of U -shaped form is on the girder steel, and the aluminum plate's of U -shaped form opening deviates from large -current cable, and aluminum plate is equipped with the material outward for the passageway of the non - conducting material of non - magnetic?materials preparation, the cross -section of passageway is rectangular ring shape, installs updraft ventilator at the end of passageway, and the air -blast device is installed to the initiating terminal of passageway. The utility model discloses a girder steel cooling device has aluminum plate through wrapping up on the girder steel, aluminum plate has high conductivity, produces induced -current and induced magnetic field, offsets the magnetic field of large -current cable production, makes the magnetic field of passing the girder steel reduce by a wide margin, and the induced current of production also red
