| 摘要 |
The invention is a hybrid cooling tower (1) for a hybrid cooling system; the hybrid cooling tower comprising - a tower shell (4) being supported by tower shell legs (16) above a ground level, providing an air intake between the ground level and a lower edge of the tower shell (4); - a wet cooled segment (3) arranged inside of the tower shell (4) and having wet cooling cells (8) arranged at a distance from the tower shell (4) and receiving cooling air through the air intake and via first louvers; - wet fans (9) arranged on top of the wet cells (8) for inducing upwards humid air exhaust flow; - a dry cooled segment (2) being arranged outside of the tower shell (4) above said air intake for wet cells (8), the dry cooled segment (2) having air coolers being arranged as vertical cooling deltas (5) around the tower shell (4) equipped with second louvers for controlling cooling air inlet, the dry cooled segment (2) being supported by cooling delta legs (15), the tower shell (4) having inlet openings (20) arranged along the dry cooled segment (2) for the air warmed up by the dry cooled segment (2); and - dry fans (7) arranged in at least some of the inlet openings (20) of the tower shell (4), for inducing mechanical draft for the dry cooled segment (2) and for driving air warmed up by the dry cooled segment (2) into mixture with the humid air exhaust flow; wherein the tower shell (4) has a height of at least 2 times that of the cooling deltas (5) for inducing a natural draft; and wherein the hybrid cooling tower (1) further comprises an inside cover (12) defining an air duct space (11) between the air intake and the wet cells (8), the inside cover (12) separating ambient air streaming towards the wet cells (8) and the warmed up air entering the tower shell (4) via said inlet openings (20). |
