[0024] Example 1, as Figures 1-4As shown, a cutting fluid backflow cooling device includes a cooling box 1, a backflow pipe 2 is arranged on the upper side of the cooling box 1, the backflow pipe 2 extends to the upper side of the inside of the cooling box 1, and a splash structure is connected to the bottom of the backflow pipe 2. The used cutting fluid flows back along the backflow pipe 2 to the inside of the cooling box 1 for cooling. The splash structure splashes the cutting fluid in the backflow pipe 2 to the lower side of the inside of the cooling box 1. The splash structure includes a communication pipe 6 and a splash disc 7, the bottom of the communication pipe 6 is connected to the splash disc 7, the bottom side of the communication pipe 6 is provided with a communication hole 8, the cutting fluid flows through the backflow pipe 2 and the communication hole 8 to gather on the splash disc 7, and then falls from the periphery of the splash disc 7. The cutting fluid is splashed to the lower side of the inside of the cooling box 1 through the splash structure, which increases the contact area of the cutting fluid and the air, thereby accelerating the heat dissipation speed of the cutting fluid. During the splashing process, the cutting fluid is dispersed into fine droplets, which fall under the action of gravity and exchange heat with the air, which helps to quickly reduce the temperature of the cutting fluid.

[0025] A cooling cavity 3 is arranged below the cooling box 1, the cooling cavity 3 is provided with a cooling pipe 4 which penetrates left and right, and a cooling fan 5 is arranged on the side of the bottom of the cooling box 1, which blows the gas in the cooling pipe 4 to flow. The backflow cutting fluid is accumulated in the cooling cavity 3 below the cooling box 1 through splashing, and the cooling fan 5 is started to drive the cooling pipe 4 to cool. After the cutting fluid is accumulated in the cooling cavity 3 through splashing, it not only dissipates heat through natural convection of air, but also is directly affected by the flowing gas in the cooling pipe 4. The cooling fan 5 blows the gas in the cooling pipe 4 to flow, which accelerates the air flow in the cooling cavity 3, thereby enhancing the heat exchange between the cutting fluid and the air and improving the cooling efficiency. The combination of the two makes the cooling effect of the cutting fluid more significant.

[0026] Example 2, in combination Figures 5-6The embodiment has the same parts as embodiment 1, and the difference is that the splashing structure in the embodiment comprises a communicating pipe 6 and a splashing part 9, the splashing part 9 is close to the tubular structure as a whole and communicates with the communicating pipe 6, a first slot body 10 and a second slot body 11 are arranged in the middle of the splashing part 9 and penetrate the splashing part 9 from front to back, a first splashing disc 12 is arranged on the first slot body 10, a second splashing disc 13 is connected to the bottom of the second slot body 11, and the first splashing disc 12 and the second splashing disc 13 are coaxially arranged. The returned cutting fluid falls on the first splashing disc 12 and the second splashing disc 13 from above the communicating pipe 6 and the splashing part 9, the diameter of the second splashing disc 13 is greater than that of the first splashing disc 12, and this design makes the cutting fluid form a layered effect during splashing. The cutting fluid is first preliminarily dispersed by the first splashing disc 12, and then is further finely dispersed on the second splashing disc 13, so that the contact area of the cutting fluid and air is increased, and the cooling efficiency is improved. The layered splashing makes the cutting fluid form more fine droplets in the cooling cavity 3, the droplets continuously fall under the action of gravity and exchange heat with air, and the heat in the cutting fluid is effectively dissipated into the air. Due to the design of the first splashing disc 12 and the second splashing disc 13, the cutting fluid can be uniformly distributed in different areas of the cooling cavity 3 during splashing, so that the excessive concentration or absence of the cutting fluid in a certain area is avoided, and the uniformity of the cooling effect is ensured.

[0027] In order to further optimize the splashing effect, a center through hole 14 is arranged in the middle of the first splashing disc 12 and penetrates the first splashing disc 12 from top to bottom, and the outer wall of the first splashing disc 12 is in an arc structure, a tapered block 15 is arranged above the middle of the second splashing disc 13, the center through hole 14 arranged in the middle of the first splashing disc 12 allows part of the cutting fluid to pass directly, so that the accumulation of the cutting fluid on the first splashing disc 12 is reduced, and the cooling efficiency caused by excessive accumulation is avoided. The tapered block 15 can guide the cutting fluid to be more uniformly distributed on the second splashing disc 13, which helps to reduce the splashing range of the cutting fluid during splashing. In the embodiment, the shape of the cooling pipe 4 is a spiral structure, and the design of the spiral structure makes the length of the cooling pipe 4 greatly extended in the limited space, so that the contact area between the cutting fluid and the cooling pipe 4 is increased, and the heat exchange efficiency is improved.
