Claims

[Claims for Utility Model Registration] 1. A plurality of closed heat exchangers are arranged vertically and hierarchically under the upper water tank of the cooling tower, and the supply section and discharge section of each closed heat exchanger are connected to each other. Each header is detachably connected to a corresponding common supply header or discharge header, and the discharge header is located closer to the outside air intake of the cooling tower, and the supply header is located closer to the exhaust port of the cooling tower. In the cooling tower, the upper water tank is a first water tank near the outside air intake;
A supply pipe that is divided into at least two water tanks including a second water tank near the exhaust port and supplies spray water to at least the second water tank is equipped with an on-off valve, and below the boundary between the two water tanks, In the hierarchical closed heat exchanger group, a water droplet removal section is vertically interposed between the outside air intake port and the exhaust port, and a water droplet removal section is provided on the air flow downstream side of the water droplet removal section. A cross-flow cooling tower characterized in that spray water guide bodies for distributing and supplying spray water to a closed heat exchanger portion located below a second water tank are arranged along a water droplet removal section. 2 A filling plate is interposed between the upper and lower straight pipes for heat exchange in the closed type heat exchanger group located below the first water tank, and the heat in the closed type heat exchanger group located below the second water tank is A plurality of heat exchange fins are attached to the replacement straight pipe section in parallel with the air flow direction at intervals, and the spray water guide body is integrally formed at the upstream end of these fins. A cross-flow cooling tower according to claim 1 of the utility model registration claim characterized by: 3. The cross-flow cooling tower according to claim 1, wherein the spray water guide body is a flat spray water guide fin. 4. The water droplet removal section is constructed by arranging a plurality of synthetic resin plates in parallel and forming an air passage between adjacent synthetic resin plates through which the air taken in from the outside air intake port flows toward the exhaust port side, A request for registration of a utility model characterized in that the air passage consists of a straight passage parallel to the direction of air flow, and a bent passage that communicates with the straight passage and is bent at at least one place in a horizontal or vertical plane. A cross-flow cooling tower according to item 1. 5 The depth dimension of the entire water droplet removal section in the air flow direction is approximately one-third of the total depth dimension of the closed heat exchanger.
The cross-flow type cooling tower according to claim 1 of the utility model registration claim, characterized in that the cooling tower is of a certain degree. 6. The cross-flow type cooling tower according to claim 4, wherein each of the air passages on the air inlet side and the air outlet side in the water droplet removal section are the straight passages. 7. Each of the air passages on the air flow inflow side and the air flow outflow side in the water droplet removal section is the bent passage,
The cross-flow type cooling tower according to claim 4, wherein each air passage in the intermediate portion is a straight passage. 8. The cross-flow cooling tower according to claim 1, wherein the supply pipes for the first and second water tanks are each provided with an on-off valve. 9. The cross-flow cooling tower according to claim 1, wherein the opening/closing valve of the second water tank is an electromagnetic valve that opens and closes in response to the outlet temperature of the lower water tank of the cooling tower.
