PURPOSE:To eliminate the influence of cross wind to stabilize the control of a wind quantity by hanging from a top board at righthand and lefthand both sides of a case, providing a shielding plate for covering the upper part of a V-shapedly arranged heat exchangers, opening an inlet thereunder and providing a wind shielding plate from the bottom of a ravine between heat exchangers. CONSTITUTION:Heat exchangers 6 are V-shapedly arranged from the left upper part of a case 2 to the right upper part thereof through the downward of a fan 5, shielding plates 2a are provided over the upper part of the heat exchangers 6 on both the sides of right and left of the case 2 and an inlet 3 is opened thereunder. The upper part of the heat exchangers 6 is protected from cross wind by the shielding plates 2a. The cross wind passing through the heat exchanger 6 of the one hand by a wind screening plate 8 provided on a V-shaped ravine is prevented from flowing in the heat exchangers 6 of the other hand. Accordingly, the production of disturbances of correspondence of wind quantity control and pressure control by the cross wind can be prevented and the wind quantity control can stably be performed. Particularly, when the upper end of the screening plate 8 and the lower end of the shielding plates are overlapped each other, further effects are exhibited. |
