PROBLEM TO BE SOLVED: To provide cooling tower equipment capable of being improved in cooling performance. SOLUTION: In a circulation channel 8 formed between cooling tower lines 5 and 6, air, which has come through inlets at both end portions of the circulation channel 8, flows toward the central portion thereof while being sequentially drawn through the air inlets of the cooling towers 4 on the way. However, since a channel cover 7 has a shape of catenoid, in which the cross sections S1 of a circulation channel 8 at both end inlets thereof are set larger than that S2 at the central portion thereof, the flow rate of air in the circulation channel 8 is almost constant over the entire length thereof. As a result, pressure loss until the air is drawn into a cooling tower 4 at the center of the circulation channel 8 is reduced and a predetermined amount of air drawn into each cooling tower 4 for cooling the same is secured.
