[0002] In the use of CNC machine tools, coolant is needed to cool and protect the cutting position, and then the coolant is returned to the coolant storage tank for recycling. However, after prolonged use, the coolant temperature rises, which reduces the cooling and protection effect. Therefore, a cooling structure is needed to cool the coolant. The reference patent announcement number CN 222221985 U describes a cooling device for CNC machine tools that cools the coolant by installing a cooling box on the side of the coolant storage tank. However, it cannot be installed separately and positioned, making it impossible to directly plug and position for use.

Detailed Implementation
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] like Figure 1-5 As shown, this utility model is a cooling structure for CNC machine tool coolant, including a coolant storage tank 1, which can be installed on the side of the CNC machine tool to allow coolant to flow into the cutting position for tool cooling and protection. A cover plate 11 is installed on the upper end of the coolant storage tank 1, and a protective box 17 is fixedly connected to the upper end of the cover plate 11. This protective box 17 can be directly snapped onto the coolant storage tank 1, allowing for separate installation and positioning, high efficiency and stability, and adaptability to different CNC machine tools. A circulation pipe 12 is fixedly connected to one side of the coolant storage tank 1, and a circulation pump 13 is fixedly connected to the upper end of the circulation pipe 12. A return pipe 14 is fixedly connected to the outlet of the circulation pump 13, allowing coolant to be drawn by the circulation pump 13, circulated upwards, and then returned to the coolant storage tank. Inside the coolant storage tank 1, a flexible hose 15 is fixedly installed at the lower end of the circulation pipe 12, and a perforated ball 16 is fixedly connected to the lower end of the flexible hose 15. The ball 16 can automatically drop to the bottom of the coolant storage tank 1, so that the coolant circulates from the bottom and then flows back to the top. Alternatively, it can be cooled by external heat exchange and then flow back, which is uniform and efficient. A heat exchange component 2 is fixedly connected between the circulation pipe 12 and the return pipe 14, and the heat exchange component 2 is fixedly connected to the inside of the protective box 17. The upper end of the protective box 17 is provided with a blower component 3, and the blower component 3 is located above the heat exchange component 2. By blowing air onto the heat exchange component 2 through the blower component 3, forced ventilation can be used for heat exchange and cooling, thereby improving efficiency. Furthermore, the heat exchange assembly 2 includes a bent pipe 21 and heat exchange plates 22. The two ends of the bent pipe 21 are respectively connected to the ends of the circulation pipe 12 and the return pipe 14, and the heat exchange plates 22 are connected to the outer surface of the bent pipe 21 at equal intervals. The heat exchange plates 22 are fixedly snapped onto the surface of the bent pipe 21, which can increase the number of connection points, thereby increasing the heat exchange area and improving the heat exchange and cooling efficiency. Furthermore, one side of the heat exchange plate 22 is provided with a snap-fit groove 24, and a fixing block 25 is fixedly connected to the surface of the snap-fit groove 24. The snap-fit groove 24 is fixedly connected to the surface of the bent tube 21 through the fixing block 25. After the snap-fit groove 24 is snapped and positioned, the fixing blocks 25 on both sides can assist in supporting the surface of the bent tube 21, increasing the stability of the connection. It can also be manually disassembled for cleaning to avoid surface dust affecting the heat dissipation effect and facilitate maintenance. Furthermore, the lower end of the bend 21 is fixedly connected to a fixing frame 23, which is fixedly connected to the upper surface of the cover plate 11. The bend 21 is fixedly connected by the fixing frame 23, which can support and position it, ensuring the stability of use. Furthermore, the blower assembly 3 includes an adjustment plate 32 and a fan 33. The fan 33 is fixedly installed on the lower surface of the adjustment plate 32, and the adjustment plate 32 is hinged to the side of the protective box 17 via a hinge seat 31. By installing the fan 33 through the hinged adjustment plate 32, it can be aligned directly above the bend 21, thereby blowing air downwards to accelerate air circulation and improve cooling efficiency. After flipping and locking the adjustment plate 32, the interior can be cleaned and maintained. Furthermore, the upper end of the regulating plate 32 is provided with a through groove 34, and a mesh protective plate 35 is fixedly installed inside the through groove 34. Installing the mesh protective plate 35 can isolate and protect the fan 33, ensure the safety of use, and will not affect the air intake ventilation. Furthermore, the surface of the protective box 17 is provided with an inclined air outlet groove 36, and a support plate 37 is fixedly connected to the outer surface of the protective box 17. The support plate 37 is located below the hinge seat 31. By setting the inclined air outlet groove 36, air circulation is facilitated, and the internal structure can also be protected. In practical use, after connecting the cover plate 11 to the upper end of the coolant storage tank 1, the hose 15 and the perforated ball 16 can be inserted into the coolant. The circulation pump 13 is started to draw coolant into the bend 21, and then the coolant flows back to the coolant storage tank 1 from the return pipe 14 at the other end. At the same time, the fan 33 is started to blow air downwards, which can directly blow air onto the surface of the heat exchange fins 22 and the bend 21, forcing internal ventilation and quickly removing heat. When the coolant enters the bend 21 for circulation, it can exchange heat through the surface of the bend 21 and the heat exchange fins 22, thereby achieving cooling. It can be installed as a whole on top of the cold storage tank 1 for use. It is simple and efficient. After use, it can be supported by the hinge seat 31, flipped open to open the adjustment plate 32, and then inverted onto the side support plate 37. The fan 33 can be placed facing upwards for easy maintenance and replacement without interference. At the same time, after opening the protective box 17, the surface of the bend 21 and the heat exchange fins 22 inside can be cleaned to remove dust and ensure heat dissipation effect, which is conducive to maintenance and use.
[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
