DETAILED DESCRIPTION

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] As shown in the figure, Figure 1 Figure 5 A composite finned tube evaporative air cooler assembly, comprising a tower box 1, a plurality of composite finned tube bodies 2 are fixedly connected inside the tower box 1, and a spray pipe 3 is fixedly connected above the composite finned tube bodies 2, a spray head 4 is fixedly connected to the bottom surface of the spray pipe 3, and a water trap 5 is fixedly connected above the spray pipe 3, a fan 6 is fixedly connected above the water trap 5, a water collecting tank 7 is fixedly connected to the bottom of the tower box 1, and a pump body 8 is fixedly connected to the right side wall of the water collecting tank 7, and a conveying pipe 9 is fixedly connected between the pump body 8 and the spray pipe 3;

[0023] The principle of the composite finned tube evaporative air cooler assembly is as follows:

[0024] The hot fluid flows in the composite finned tube body 2, and after the fan 6 is started, a large amount of air is sucked into the tower box 1, and the air exchanges heat with the hot fluid in the pipe when flowing through the composite finned tube body 2, and carries away part of the heat, thereby preliminarily reducing the temperature of the hot fluid. At the same time, the pump body 8 sends the water in the water collecting tank 7 to the spray pipe 3 through the conveying pipe 9, the water is sprayed out from the spray head 4, and a water film is formed on the surface of the composite finned tube body 2. When the air continues to flow through the wet surface of the composite finned tube body 2, the water absorbs heat and begins to evaporate. Water evaporation requires a large amount of latent heat of vaporization, which is mainly derived from the heat transferred to the surface of the composite finned tube body 2 through the pipe wall and the heat of the air itself, thereby further strengthening the cooling effect and greatly reducing the temperature of the hot fluid. During the heat and humidity exchange process between the air and the water film, part of the water vapor will rise with the air flow, and the water trap 5 can effectively separate the water vapor carried in the air to avoid excessive loss of water. At the same time, the water is also washed into the water collecting tank 7 for recycling, while ensuring that the humidity of the discharged air meets the requirements to prevent affecting the surrounding environment. With the continuous evaporation of water, the water in the water collecting tank 7 will decrease, and new water can be continuously supplied to maintain the stability of the spraying and cooling process.
