[0021] In order to make the objectives, technical solutions and beneficial effects of the present invention more clear, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0022] like Figure 1-7 As shown, the present invention provides a circulating water energy-saving and high-efficiency heat dissipation device, comprising a hydraulic pump Ⅰ1, a heat dissipation tube Ⅰ2, a heat dissipation tube Ⅱ3, a connecting pipe 4, and a hydraulic pump Ⅱ5; one end of the hydraulic pump is connected to the circulating water outlet of the production equipment through the connecting pipe 4, and the other end is connected to the top of the heat dissipation tube Ⅰ2 through the connecting pipe 4; the heat dissipation tube Ⅰ2 is installed on the top of the heat dissipation tube Ⅱ3, and the bottom of the heat dissipation tube Ⅰ2 is provided with a water outlet to connect with the heat dissipation tube Ⅱ3; the bottom of the side wall of the heat dissipation tube Ⅱ3 is connected to the hydraulic pump Ⅱ5 through the connecting pipe 4, and the hydraulic pump Ⅱ5 is connected to the circulating water inlet of the production equipment; a stirring device 6 for pre-dissipating the circulating water is installed in the heat dissipation tube Ⅰ2; a diffusion device 8 for dispersing water is installed at the top of the heat dissipation tube Ⅱ3 through a plurality of connecting rods 7, and the diffusion device 8 is a cylindrical triangular prism structure that passes through from top to bottom, and the side wall of the diffusion device 8 is evenly provided with a plurality of through holes that are convenient for water flow dispersion. When the heat dissipation device is working, under the action of the hydraulic pump Ⅰ1, the circulating water in the production equipment flows out from the production equipment through the hydraulic pump Ⅰ1 and the connecting pipe 4 into the heat dissipation tube Ⅰ2. The stirring device 6 stirs and dissipates the circulating water in the heat dissipation tube Ⅰ2 to reduce the temperature of the circulating water. Then the circulating water that has undergone preliminary cooling flows into the heat dissipation tube Ⅱ3 from the water outlet opened at the bottom of the heat dissipation tube Ⅰ2, passes through the diffusion device 8, and the diffusion device 8 disperses the water and flows down along the diffusion device 8 with a triangular prism structure. The through holes provided on the side wall of the diffusion device 8 facilitate the dispersion of the water flow and fall to the bottom of the heat dissipation tube Ⅱ3. Under the action of the hydraulic pump Ⅱ5, the cooled circulating water in the heat dissipation tube Ⅱ3 is sent back to the production equipment for heat exchange. In the process of the circulating water being dispersed and falling, the contact area between the circulating water and the air increases, which accelerates the heat exchange rate, thereby reducing the temperature of the circulating water. Through this cooling method, the consumption of electric energy is reduced, energy is saved, and costs are reduced.

[0023] like Figure 4As shown, the stirring device 6 includes a motor Ⅰ61, a stirring rod 62, and a stirring blade 63. The motor Ⅰ61 is installed on the top of the heat dissipation tube Ⅰ2. The upper end of the stirring rod 62 is rotatably installed on the top of the heat dissipation tube Ⅰ2 and is transmission-connected to the motor Ⅰ61. The stirring blade 63 is evenly installed on the side wall of the stirring rod 62. The stirring rod 62 is driven to rotate by the motor Ⅰ61, and the stirring rod 62 drives the stirring blade 63 to rotate. The stirring blade 63 stirs the circulating water in the heat dissipation tube Ⅰ2 to dissipate heat, thereby preliminarily reducing the temperature of the circulating water, so as to facilitate the next step of heat dissipation and improve the cooling effect of the circulating water.

[0024] like Figure 2-5 As shown, the upper end of the connecting rod 7 is connected to the outer ring of the bearing 9 installed at the top of the heat dissipation tube II 3, and the diffusion device 8 is located below the water outlet at the top of the heat dissipation tube II 3. The fan blade 10 is installed in the diffusion device 8. When the circulating water in the heat dissipation tube I 2 that has been stirred and cooled flows downward from the bottom into the heat dissipation tube II 3, the circulating water impacts the diffusion device 8, causing the water flow to disperse, which is beneficial to cooling. At the same time, the water flow hits the fan blade 10, causing the fan blade 10 to drive the diffusion device 8 to rotate along the bearing 9, causing the water flow to disperse to all sides, increasing the contact surface between water and air, which is beneficial to the heat exchange between the circulating water and the air and improving the heat dissipation efficiency.

[0025] like Figure 5 As shown, the fan blades 10 are evenly mounted on the side walls of the fixed shaft 11 installed in the diffuser 8, and the upper and lower ends of the fixed shaft 11 are connected to the inner wall of the diffuser 8 through the mounting rods 12. The fixed shaft 11 on which the fan blades 10 are mounted is fixedly connected to the inner wall of the diffuser 8 through the mounting rods 12 at the upper and lower ends, so that the fan blades 10 rotate when impacted by the water flow, and the fan blades 10 drive the diffuser 8 to rotate together, so that the water flow passing through the diffuser 8 is subjected to an outward centripetal force, so that the water flow diverges outward, and the heat dissipation efficiency is improved.

[0026] like Figure 6As shown, the top of the heat dissipation tube Ⅰ2 and the heat dissipation tube Ⅱ3 are connected with a heat dissipation tube 13, and a plurality of condensing tubes 14 are evenly connected to the heat dissipation tube 13. The condensing tube 14 passes through the heat dissipation tube 13 from top to bottom. The bottom of the connection between the heat dissipation tube 13 and the condensing tube 14 is connected with a return pipe 15, and the other end of the return pipe 15 is connected to the connecting pipe 4 between the heat dissipation tube Ⅱ3 and the hydraulic pump Ⅱ5. The heat dissipated by the circulating water in the heat dissipation tube Ⅰ2 and the heat dissipation tube Ⅱ3 is dissipated to the outside from the heat dissipation tube 13, thereby taking away the heat and reducing the temperature of the circulating water. The hot air dissipated from the heat dissipation tube 13 carries a large amount of water vapor. When the heat is dissipated, a large amount of water will be lost. When the hot air passes through the condensing tube 14 in the heat dissipation tube 13, due to the low temperature of the condensing tube 14, the water vapor in the hot air condenses on the outer wall of the condensing tube 14, flows downward along the condensing tube 14, flows into the return pipe 15, flows back to the connecting pipe 4, and flows back to the production equipment together with the cooled circulating water, thereby reducing the water loss.

[0027] like Figure 7 As shown, the side wall of the heat dissipation tube II3 is connected to two centrally symmetrical air inlet tubes 16, which are tangent to the side wall of the heat dissipation tube II3. A fan 17 for blowing air into the heat dissipation tube II3 is installed in the air inlet tube 16. The fan 17 blows the outside air into the heat dissipation tube II3, and the blowing direction is tangent to the inner wall of the heat dissipation tube II3, so that the wind direction rotates along the inner wall in the heat dissipation tube II3 and blows out from the heat dissipation tube 13, so as to take away the heat and improve the heat dissipation efficiency of the circulating water.

[0028] like Figure 7 As shown, the fan 17 is mounted on a cross mounting frame 18 provided at the end of the air inlet tube 16, and is in transmission connection with a motor II 19 mounted on the cross mounting frame 18. The motor II 19 drives the fan 17 to rotate, blows outside air into the heat dissipation tube II 3 to take away the heat, and the cross mounting frame 18 facilitates outside air to enter the heat dissipation tube II 3.

[0029] like Figure 6 As shown, a reduction cylinder 20 having a larger diameter than the heat pipe 13 and coaxial with the heat pipe 13 is provided at the connection between the heat pipe 13 and the condenser pipe 14. The condenser pipe 14 passes through the reduction cylinder 20, and the return pipe 15 is connected to the bottom of the reduction cylinder 20. When the hot air in the heat pipe 13 flows through the reduction cylinder 20, the hot air flow rate slows down due to the increase in the diameter of the reduction cylinder 20, and the contact area between the hot air and the condenser pipe 14 increases, which is conducive to the condensation of water vapor in the hot air on the surface of the condenser pipe 14, and flows back to the connecting pipe 4 from the return pipe, thereby improving the condensation effect of the water vapor.

[0030] Working process:

[0031] When the heat dissipation device is working, under the action of the hydraulic pump Ⅰ1, the circulating water in the production equipment flows out from the production equipment through the hydraulic pump Ⅰ1 and the connecting pipe 4 into the heat dissipation tube Ⅰ2. The stirring device 6 stirs and dissipates the circulating water in the heat dissipation tube Ⅰ2 to reduce the temperature of the circulating water. Then, the circulating water that has undergone preliminary cooling flows into the heat dissipation tube Ⅱ3 from the water outlet opened at the bottom of the heat dissipation tube Ⅰ2, passes through the diffusion device 8, and the diffusion device 8 disperses the water and flows down along the diffusion device 8 with a triangular prism structure. The through holes arranged on the side wall of the diffusion device 8 facilitate the dispersion of the water flow. At the same time, the water flow hits the fan blades 10, so that the fan blades 10 drive the diffusion device 8 to rotate along the bearing 9, so that the water flow is dispersed to the surroundings, increasing the contact surface between the water and the air, thereby facilitating the heat exchange between the circulating water and the air. The circulating water falls into the heat dissipation tube At the bottom of Ⅱ3, under the action of hydraulic pump Ⅱ5, the circulating water cooled in heat dissipation tube Ⅱ3 is sent back to the production equipment for heat exchange; fan 17 blows outside air into heat dissipation tube Ⅱ3, and the blowing direction is tangent to the inner wall of heat dissipation tube Ⅱ3, so that the wind direction rotates along the inner wall in heat dissipation tube Ⅱ3 and blows out from heat dissipation tube 13, so as to take away the heat and reduce the temperature of circulating water. The hot air emitted from heat dissipation tube 13 carries a large amount of water vapor. While the heat is dissipated, a lot of water will be lost. When the hot air passes through the condenser tube 14 in the heat dissipation tube 13, due to the low temperature of the condenser tube 14, the water vapor in the hot air condenses on the outer wall of the condenser tube 14, flows downward along the condenser tube 14 into the return pipe 15 and flows back to the connecting pipe 4, and flows back to the production equipment together with the cooled circulating water, thereby reducing the water loss.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
