A circulation mechanism 8 is provided on one side of the spindle housing 1, and the circulation mechanism 8 circulates the liquid after absorbing heat, and then cools the liquid through natural temperature and electric assistance to achieve liquid circulation cooling and filtration treatment.

[0022] In this embodiment, the cooling mechanism 5 includes a cooling water tank 4, a diverter pipe 6, a partition panel 12, a thermoelectric cooling sheet 13, a plate fan 14 and an internal cooling chamber 15. The diverter pipe 6 is connected to the left and right sides of the cooling water tank 4. The interior of the cooling water tank 4 is provided with a partition panel 12. The interior of the partition panel 12 is provided with thermoelectric cooling sheets 13 at equal intervals. The bottom end of the cooling water tank 4 is provided with a plate fan 14. The interior of the spindle housing 1 is symmetrically provided with an internal cooling chamber 15. The liquid is diverted by the symmetrically arranged diverter pipes 6, and the liquid is circulated and cooled by two groups of internal cooling chambers 15.

[0023] In this embodiment, the spindle housing 1 is connected to one end of the shunt pipe 6 through an internal symmetrically arranged internal cooling chamber 15 , and the internal equipment of the spindle housing 1 is subjected to heat absorption treatment by the low-temperature liquid inside the internal cooling chamber 15 .

[0024] In this embodiment, the circulation mechanism 8 includes a spiral copper tube 9, a circulation pump 10 and a filter disc 11. The bottom end pipe of the spindle housing 1 is connected to the filter disc 11. The bottom end of the filter disc 11 is connected to the input end of the circulation pump 10. The output end of the circulation pump 10 is connected to one end of the spiral copper tube 9. The other end of the spiral copper tube 9 is connected to one end of the refrigeration water tank 4. The heat-absorbing liquid is injected into the interior of the spiral copper tube 9 through the circulation pump 10, and the heat-absorbing liquid is cooled and refluxed through the spiral copper tube 9.

[0025] In this embodiment, the filter disc 11 is connected to one end of the refrigeration water tank 4 through a spiral copper tube 9 provided at the bottom end.
