[0018] As Figures 1 - 5 shown, the present utility model discloses a cooling tower with a cooling water temperature control device, including:

[0019] Cooling tower body 1 and top heat dissipation device 2, and the top heat dissipation device 2 is fixedly connected to the center of the upper end of the cooling tower body 1. A temperature control device 3 is arranged inside the cooling tower body 1, and the front end of the cooling tower body 1 is connected to a water outlet water pump box 5 through a water outlet pipe 4; The top heat dissipation device 2 includes a connecting pipe 21. The connecting pipe 21 is fixedly connected to the center of the upper end of the cooling tower body 1. Through the connection between the top heat dissipation device 2 and the cooling tower body 1, the heat dissipation function can be realized; The temperature control device 3 includes a return pipe 31. The return pipe 31 is fixedly arranged inside the cooling tower body 1. Through the cooperation between the temperature control device 3 and the cooling tower body 1, the cooling water can be sprayed and cooled through the cooling tower body 1.

[0020] Embodiment 1: Please refer to Figures 1 to 4 , it can be seen that in order to better exert the heat dissipation function of the cooling tower body 1, heat dissipation holes are opened at the upper end of the cooling tower body 1 to cooperate with the top heat dissipation device 2, and heat is dissipated by volatilization under the action of the top heat dissipation device 2. A heat dissipation cavity is opened inside the cooling tower body 1 to cooperate with the temperature control device 3, and a connection hole is opened in the cooling tower body 1 to cooperate with the temperature control device 3 and the water outlet pipe 4, so that the cooling tower body 1 provides basic conditions for the use of other structures. A cross support plate 22 is fixedly connected inside the connecting pipe 21. The cross support plate 22 supports a heat dissipation motor box 24 through eight groups of support rods 23. A fan 25 is rotatably connected to the bottom of the heat dissipation motor box 24. The cross support plate 22 is provided with a rotating groove hole to cooperate with the heat dissipation motor box 24. Through the cooperation between the cross support plate 22 and the support rods 23, the heat dissipation motor box 24 can stably drive the fan 25 to rotate and operate at the upper end. The middle end of the return pipe 31 is connected to a regulating valve 32, and the upper end of the return pipe 31 is connected to a connecting support pipe 33. Eight groups of dripping heat dissipation pipes 34 are arranged between the connecting support pipes 33, so that the cooling water is sprayed out through the dripping heat dissipation pipes 34, increasing the heat dissipation capacity of the cooling tower body 1. The bottom of the connecting support pipe 33 and the dripping heat dissipation pipe 34 is fixedly connected to a connecting rod 35, and the two ends of the bottom of the connecting rod 35 are fixedly connected to two groups of side support columns 36, so that the dripping heat dissipation pipes 34 stably spray cooling water under the support of the connecting rod 35 and the side support columns 36. The bottom of the regulating valve 32 is electrically connected to a control circuit pipe 37. The return pipe 31 is L-shaped, the connecting support pipe 33 is U-shaped, and the bottom of the dripping heat dissipation pipe 34 is provided with a plurality of water flow spraying holes to spray water downward.

An electric telescopic rod 322 is connected to the upper end of the fixed sleeve block 321, and a switch plate 323 is connected to the bottom of the electric telescopic rod 322. Grooves that cooperate with the switch plate 323 are formed inside the fixed sleeve block 321 and the electric telescopic rod 322. The electric telescopic rod is controlled to expand and contract through the control circuit tube 37, and then the switch plate 323 is driven to open and close, completing the temperature control process.

[0022] Working principle: When the cooling tower is in use, when the temperature of the cooling water drops below 22 degrees, temperature adjustment and control are required. The electric telescopic rod 322 is controlled through the control circuit tube 37 to make the electric telescopic rod 322 contract. Then, the switch plate 323 is pulled to open the closed pipeline, so that during the flow of the cooling water through the return pipe 31, part of the cooling water does not spray to the lower part through the drip cooling pipe 34 but directly flows out to increase the temperature of the cooling water, thereby achieving the control effect.
