At present, the mechanical ventilation cooling tower is generally adopted as cooling equipment in cooling circulating water, and in the using process of the mechanical ventilation cooling tower, the energy consumption is huge, a part of resources can be lost when the cooling tower splashes water, serious problems such as exceeding standard of noise can be generated, and the problems are solved by developing a novel cooling tower in urgent need. At present, the main equipment for cooling circulating water at home and abroad is a cooling tower, a fan impeller is driven to rotate, and a mode of taking air, dissipating heat and cooling is mechanical transmission, and a mechanical transmission device of the cooling tower is as follows: the device comprises a motor, a water turbine, a speed reducer and a fan (impeller). The flow direction of water and air flow can be divided into a counter-flow cooling tower and a cross-flow cooling tower, the shape can be divided into a square and a rectangle, the square is mainly used for the counter-flow cooling tower, and the rectangle is mainly used for the cross-flow cooling tower. The water distribution mode can be divided into a plurality of modes, such as pipe type water distribution, disc type (pool type) water distribution, groove type water distribution and the like. The cooling tower works according to the principles of contact heat exchange between water and air and evaporative cooling, and the basic principle is that hot water enters a water distribution device at the upper part of the cooling tower through an upper water pipe, then, hot water is uniformly sprayed on the water spraying filler pieces through the water distribution device, the hot water flows downwards along the surfaces of the filler pieces, forming uniform water films on the concave-convex surfaces of the water spraying packing sheets, sucking cold air into the tower from the air inlet under the action of rotation of the fan impeller, penetrating through gaps among the packing sheets, exchanging heat with the water films on the packing sheets, absorbing heat in the water films, simultaneously, because of the negative pressure in the tower, part of water is evaporated, thereby taking away the heat in the water, finally discharging the water out of the tower and dissipating the water into the atmosphere, the hot water with heat taken away is cooled and finally collected into a water collecting basin (pool) at the bottom of the cooling tower to enter equipment needing cooling for the next circulation. In the counter-flow cooling tower, the water flow and the air flow in counter-flow, that is, the air flow enters from the air inlet at the lower part of the cooling tower and then turns to flow vertically upwards, while the hot water is dispersed downwards from the upper water distribution device and flows into the water spraying filler to exchange heat with the cold air flow and then falls into the water collecting basin (pool), the square counter-flow cooling tower generally adopts a tubular water distribution mode to distribute water, the spray heads are distributed on the water distribution pipe, and the hot water is sprayed downwards through the spray heads and sprayed on the water spraying filler. In the cross-flow cooling tower, water flow and air flow in a vertical direction, namely, the air flow enters from air inlets at two sides of the cooling tower and passes through the packing along the horizontal direction, hot water flows out from a nozzle (or a small hole) at the bottom of a water distribution disc at the top of the tower, the hot water is vertically and uniformly sprayed on the water spraying packing, the downward flow exchanges heat with cold air flow passing horizontally, the air flow absorbing heat is sucked by a fan impeller and discharged out of the tower, the hot water radiates heat and is cooled into cold water to fall into a water collecting basin (pool) and enter equipment needing cooling; the two cooling towers are the most widely applied cooling equipment at home and abroad at present.
