[0023] Please refer to Figures 1, 2, and 3. The spray mechanism 8 includes a water pump 81. Two symmetrically distributed water pumps 81 are fixedly installed on the right end of the tower body 1. A water inlet pipe 82 is provided at the bottom of the water pump 81 and is fixedly connected to the water tank 7. A drain pipe 83 is provided on the right end of the water pump 81 and is fixedly connected to the box body 11. The drain pipe 83 is rotatably connected to the spray pipe 4. A motor 84 is fixedly installed on the right end of the box body 11. The output end of the motor 84 is rotatably connected to the box body 11. A rotating seat 85 is fixedly connected to the left end of the output end of the motor 84. A gear 1 86 is fixedly connected to the left end of the rotating seat 85. A gear 2 87 meshes with the outside of the gear 1 86. The gear 2 87 is fixedly sleeved on the outside of the spray pipe 4. By designing the spray mechanism 8, uniform spraying of cooling water can be achieved.
[0024] Please refer to Figures 1, 2, and 4. The locking mechanism 9 includes a groove 91. The rotating seat 85 has a groove 91 inside. A retaining ball 92 is movably fitted inside the groove 91. There are multiple grooves 91, which are arranged in a ring and evenly distributed inside the rotating seat 85. By designing multiple grooves 91, the retaining ball 92 can roll into the grooves 91 at different positions. A limiting seat 93 is movably fitted on the outside of the retaining ball 92. The limiting seat 93 is fixedly connected to the housing 11. A slider 94 is movably fitted on the outside of the retaining ball 92. A sliding rod 95 is fixedly connected to the top of the slider 94.

[0025] The specific implementation process of this utility model is as follows: When it is needed to spray, the water pump 81 draws water into the water tank 7 through the water inlet pipe 82, and then the spray water is transported into the spray pipe 4 through the drain pipe 83. Finally, the cooling water is sprayed through the nozzle 5 to achieve spray cooling of the heat exchange pipe 12.
[0026] During the spraying process, when the motor 84 is working, the output end of the motor 84 can drive the rotating seat 85 to rotate, the rotating seat 85 drives the gear 1 86 to rotate, the gear 1 86 will drive the gear 2 87 to rotate, the gear 2 87 will drive the spray pipe 4 to rotate, and the spray pipe 4 will drive the nozzle 5 to rotate. The spraying angle of the nozzle 5 can be adjusted, so that the cooling water can cover the heat exchange tube 12 more evenly, improve the heat exchange efficiency, and improve the cooling effect.
[0027] When the rotating seat 85 rotates, the arc surface of the groove 91 inside the rotating seat 85 will squeeze and push the retaining ball 92, causing the retaining ball 92 to roll upward. The retaining ball 92 will drive the slider 94 and the sliding rod 95 to move upward. The slider 94 can squeeze the spring 96, which can then separate the retaining ball 92 from the groove 91. When the rotating seat 85 has finished rotating and needs to spray at a fixed point through the nozzle 5, the elasticity of the spring 96 will give the slider 94 a downward counterforce, which can push the retaining ball 92 into the groove 91 at another position. With the insertion and cooperation of the retaining ball 92 and the groove 91, the stationary rotating seat 85 can be limited, thereby achieving the purpose of limiting the stationary spray pipe 4 and the nozzle 5, and preventing the nozzle 5 from shaking due to external forces, which would affect the spray heat exchange effect on the heat exchange tube 12.
