The object of this invention is to provide a multi fan cooling unit. In this unit, a plurality of fans are rotatable at the same time, while a support column together with the fans is rotatable on its vertical axis at an angle of 360 DEG . A plurality of fan shafts are rotatably set in the hexagonal inner pipe of the support column at different heights while being angularly spaced at regular intervals, with a fan mounted to the outside end of each of the fan shafts. The fan shafts are commonly connected to a fan drive motor by a single transmission belt, thus being rotatable at the same time by the fan drive motor. The support column together with the fans is rotatable on its vertical axis at an angle of 360 DEG by a column drive motor without twisting the electric wires of the two motors. The air currents from the fans thus uniformly blow in all directions, and so this multi fan cooling unit improves its operational effect. This multi fan cooling unit is also simplified in its construction, and is reduced in its volume and size, so that the unit can be easily and effectively placed in a limited space. |
