Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a cross-flow cooling tower in which a hot water flow-down heat exchanger is filled in the cooling tower body directly below the upper water tank, the hot water flow-down heat exchanger includes a plurality of hot water flow-down heat exchangers. A passage dedicated to the cooling water flow and a substantially horizontal tunnel-shaped air dedicated flow path formed between these passages exclusively for the cooling water flow are provided, and the inlet of each air dedicated flow path is connected to the cooling tower main body. It opens to the outside air intake provided in the cooling tower, and its discharge port opens to the cooling tower exhaust passage.
The upper end of the passage dedicated to the cooling water flow is an inlet for the cooling water, and the lower end thereof is an opening for distributing the cooling water to the filling material filled below the hot water flowing down type heat exchanger. A cooling tower having a function of preventing white smoke generation, characterized in that the discharge port of the air flow path also opens into the cooling tower exhaust passage. (2) White smoke generation according to claim 1, wherein the width of the cooling water passage is approximately 1/2 to 1/3 of the width of the air passage. Cooling tower with prevention function. (3) The cooling tower having a white smoke generation prevention function according to claim 2, wherein the passage exclusively for cooling water flow and the passage exclusively for air are formed in a wave-like meandering manner in the vertical direction. (4) The hot water flowing-down type heat exchanger is formed integrally with the upper water tank, and the lower end of the cooling water flow-only passage forms a bottom water sprinkling port of the upper water tank. A cooling tower that has the function of preventing white smoke generation as described in the section. (5) The ceiling wall of the air-only flow path is an upwardly convex round ceiling wall that connects the cooled water inlets formed at the upper ends of the adjacent cooled water flow-only passages. A cooling tower having a white smoke generation prevention function as described in item 3. (6) The outlet of the air-only flow path has an opening/closing damper whose lower end is hinged, and the upper end thereof extends into the cooling tower exhaust passage when the opening/closing damper is opened. A cooling tower having a white smoke generation prevention function as claimed in claim 5, wherein the opening/closing damper is formed.
