DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the objectives, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0026] To solve the technical problem in the prior art that the cooling mechanism of the turntable cannot effectively cool the coolant after heat absorption, thereby affecting the heat absorption efficiency of the coolant, the present utility model provides a shaft system cooling turntable structure, which can cool the coolant after heat absorption, thereby ensuring the subsequent working efficiency of the coolant.
[0027] It should be noted that the shaft system cooling turntable structure described in the present utility model is used in but not limited to the turntable field, etc. For the convenience of description, in the present utility model, only the case where the shaft system cooling turntable structure is applied to the turntable field is taken as an example for description, and the principle of the shaft system cooling turntable structure applied to other types of equipment is essentially the same as that applied to the turntable field, and will not be elaborated here one by one.
[0028] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of the shaft system cooling turntable structure in an embodiment of the present utility model. The shaft system cooling turntable structure includes a body 1 and a cooling mechanism 4; a driving end 2 is arranged inside the body 1, and the output end of the driving end 2 extends to the outside of the body 1 and is connected to a turntable 3; the cooling mechanism 4 includes a housing 41, a spiral tube body 42, a liquid guiding end 43, a cooling box 44 and an air cooling end 45; the housing 41 is installed outside the body 1 and forms a heat dissipation chamber between the housing 41 and the outer wall of the body 1. A spiral tube body 42 is arranged in the heat dissipation chamber. One end of the spiral tube body 42 is connected to the liquid guiding end 43, and the other end is connected to the cooling box 44. The water pumping end of the liquid guiding end 43 is communicated with the cooling box 44. The air cooling end 45 is installed outside the cooling box 44 and is used to provide cold air into the cooling box 44.
[0029] In this embodiment, by arranging the housing 41 outside the body 1, and keeping a gap between the housing 41 and the body 1 to form a heat dissipation chamber, a spiral tube body 42 is arranged in the heat dissipation chamber, and the coolant in the cooling box 44 is extracted through the liquid guiding end 43 and made to move spirally in the spiral tube body 42 to adsorb the heat generated inside the body 1 when the driving end 2 operates. After the coolant adsorbs the heat, it flows back into the cooling box 44 again, and a refrigeration area is formed in the cooling box 44 through the air cooling end 45 to cool the coolant after heat absorption, thereby ensuring the subsequent heat absorption effect of the coolant.
[0030] In one of the embodiments, please refer to Figure 2 , to further improve the heat dissipation effect on the driving end 2, a plurality of ventilation holes 11 are opened at the lower end of the body 1. The driving end 2 includes a motor 21, a shaft body 22, a rotor 23 and a stator 24; the motor 21 is installed at the lower end of the body 1, and the output end of the motor 21 is connected to the shaft body 22. The upper end of the shaft body 22 is connected to the turntable 3. The outside of the shaft body 22 is connected to the rotor 23. The stator 24 is installed inside the body 1 and is located outside the rotor 23.
[0031] In this embodiment, a plurality of ventilation holes 11 are circumferentially formed at the lower end of the body 1, which has the effect of dissipating heat from the motor 21, so that the temperature generated during its operation can be discharged outward, thereby avoiding the situation where the temperature of the environment where the motor 21 is located is too high.
[0032] In one of the embodiments, please refer to Figures 1-3 , to improve the cooling effect of the device on the coolant, a plurality of heat conducting fins 411 are circumferentially arranged on the outer periphery of the body 1. One end of the heat conducting fin 411 penetrates through the housing 41 and is arranged below the spiral tube body 42. The liquid guiding end 43 includes a circulating pump 431 and a water guiding pipe 432; the water pumping end of the circulating pump 431 is communicated with the cooling tank 44 through the water guiding pipe 432, the water discharging end of the circulating pump 431 is communicated with one end of the spiral tube body 42, and the cooling tank 44 includes a first box body 441, a second box body 442 and a serpentine tube body 4421; the first box body 441 is a water storage tank, the second box body 442 is a refrigeration box, the end of the water guiding pipe 432 extends into the first box body 441, the end of the spiral tube body 42 extends into the second box body 442 and is connected to the serpentine tube body 4421, the end of the serpentine tube body 4421 extends into the first box body 441, a heat insulation layer 4422 is arranged on the inner wall of the second box body 442, and the air cooling end 45 is used for refrigerating the inside of the second box body 442. The air cooling end 45 includes a box body 451, a fan 452, a conduit 453, a mounting shell 454 and a semiconductor refrigeration sheet 455; the box body 451 and the mounting shell 454 are both mounted on the outer wall of the second box body 442, and a fan 452 is arranged inside the box body 451. The box body 451 is communicated with the mounting shell 454 through the conduit 453, and a semiconductor refrigeration sheet 455 is arranged inside the mounting shell 454. The mounting shell 454 is communicated with the second box body 442 through an air duct 456. The refrigerating surface of the semiconductor refrigeration sheet 455 is arranged inside the mounting shell 454, and a plurality of cold conducting sheets 4551 are mounted on the refrigerating surface. The heating surface of the semiconductor refrigeration sheet 455 is arranged outside the mounting shell 454. Water inlets and outlets are respectively formed on the side surface of the first box body 441, and valves are arranged on both the water inlets and outlets.
[0033] In this embodiment, a heat conduction fin 411 is arranged inside the machine body 1, and the heat conduction fin 411 penetrates through the machine body 1 and is located below the spiral tube body 42, facilitating the introduction of the heat inside the machine body 1 into the heat dissipation chamber, and the heat is carried away by the coolant inside the spiral tube body 42. After the coolant absorbs heat, it enters the serpentine tube body 4421 of the second box body 442. The wind provided by the fan 452 is used to introduce the cold air generated by the cooling surface of the semiconductor refrigeration sheet 455 into the second box body 442. Since a heat insulation layer 4422 is arranged inside the second box body 442 to enhance the cold insulation effect inside the second box body 442, when the coolant flows in the serpentine tube body 4421, it can be effectively cooled, thus avoiding the coolant temperature from being too high. The serpentine tube body 4421 is provided to extend the flow time of the coolant inside the second box body 442, enabling it to fully contact the cold air, and finally entering the first box body 441 for storage. The circulating pump 431 and the water guide pipe 432 are used to repeatedly extract it, and by opening a water inlet and a water outlet on the first box body 441, it is convenient to add or discharge the coolant.
[0034] To better understand the present utility model, the following is a detailed description of the technical solution of the present utility model in conjunction with Figures 1 to 5 When the driving end 2 drives the turntable 3 to rotate, a large amount of heat is generated when the driving end 2 operates. The heat is introduced into the heat dissipation chamber through the heat conduction fin 411, and the circulating pump 431 is driven. The circulating pump 431 and the water guide pipe 432 cooperate to extract the coolant in the first box body 441 and introduce it into the spiral tube body 42, where it spirally flows inside the housing 41 to carry away the heat. The coolant that adsorbs the heat enters the serpentine tube body 4421 in the second box body 442. The wind provided by the fan 452 is used to introduce the cold air generated by the cooling surface of the semiconductor refrigeration sheet 455 into the second box body 442. Since a heat insulation layer 4422 is arranged inside the second box body 442 to enhance the cold insulation effect inside the second box body 442, when the coolant flows in the serpentine tube body 4421, it can be effectively cooled, avoiding the coolant temperature from being too high. The cooled coolant flows back into the first box body 441 for subsequent recycling. This device is simple to operate and can effectively dissipate heat and cool down the inside of the equipment, greatly improving the service life of this device.
