[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0015] The utility model outer machine cooling tower is mainly made for the improvement of the defects of the current industrial cooling tower using the snake pipe to spray cooling water, on the one hand, the cooling is not ideal, on the other hand, impurities and attachments are easy to produce on the surface of the snake pipe.

[0016] As shown in Figure 1 and Figure 2 An environmental protection, fast heat dissipation outer machine cooling tower is combined by a closed outer machine casing, the outer machine casing 1 is square or circular, the hot and cold water exchange is carried out in the tower shell 1, and cold air is output; the cooling tower is usually placed outdoors, so the environment is very bad, and the cooling tower is matched with the indoor working inner machine to work; the top surface of the outer machine casing 1 is provided with a cooling fan 2, and the inner side circumferential wall of the outer machine casing 1 is sequentially provided with an evaporator layer 7, a water curtain layer 8 and an outermost air inlet dust layer 9 from inside to outside. The evaporator layer 7 and the water curtain layer 8 constitute double layers to reduce the air temperature and the refrigerant temperature.

[0017] The inner bottom of the outer machine casing 1 is provided with a water tank 5, and the water tank 5 is provided with a water pump 4.

[0018] The top surface of the water curtain layer 8 is respectively provided with a water spray pipe 3, the water spray pipe 3 is connected with the water pump 4, water in the water spray pipe 3 is directly sprayed to the surface of the water curtain layer 8, the air in the inner part of the outer machine casing 1 is cooled, and the water on the water curtain layer 8 flows back to the water tank.

[0019] The evaporator layer 7 is composed of a plurality of curved copper pipes laid in a plane, the copper pipes are filled with freon, and one end of the curved copper pipe is connected with an expansion valve (the working principle of the expansion valve is a known technology in the air conditioning field) through the copper pipe outlet hole 10. The other end of the curved copper pipe is connected with a titanium tube 6, the titanium tube 6 is extended to the water tank, and is always placed in the water tank 5, so that the curved copper pipe is further cooled, and the titanium tube 6 is not easy to be corroded in water.
