<p>The invention provides an auxiliary cooling device for cooling air that enhances the cooling efficiency of a heat radiation fin of an air-cooled condenser at high-temperature times such as summer, capable of preventing scales from adhering on the radiation fin surface and thereby preventing deterioration of the heat exchange efficiency during air-cooled operation and preventing corrosion of the radiation fin. A cooling mat 21 is disposed close to the radiation fin of the condenser at a predetermined distance, and intake air to the condenser is cooled by having cooling water run down the cooling mat 21. A water spray trough 22 is disposed on the upper portion of the cooling mat 21, and a plurality of cooling water outlets 43 are formed horizontally on the interior of the water spray trough, so that the cooling water discharged from the cooling water outlet 43 collides and splashes against an inner wall surface 22W of the water spray trough 22 and runs down to the upper portion of the coolingmat 21. Fibers constituting the coolingmat 21 are coated with at least either an antibacterial agent or an antifouling agent. When the fibers are coated with the antibacterial agent, the propagation of bacteria and fungus on the cooling mat can be prevented. When the fibers are coated with the antifouling agent, the dirt etc. can be removed easily from the mat and the mat can be maintained clean.</p> |
