[0026] On the one hand, the utility model lays a cooling pipe 4 on the gasket 3, and circulating coolant is passed into the cooling pipe 4 to cool the guide rail 2 above it; on the other hand, the utility model sets an air cooling structure inside the slider 1 to cool the slider 1 during its movement.

[0027] Specifically, the air cooling structure includes an air inlet 11 opened at the top of the slider 1, air outlets 12 opened at both ends of the slider 1, and an air cooling channel 13 connecting the air inlet 11 and the air outlet 12. The air inlet 11 is connected to the fan through a connecting pipe 14. Furthermore, a plug for closing the air outlet 12 is provided in the air outlet 12.

[0028] On the one hand, by blowing air through the air cooling channel 13 by the fan, the inside of the slider 1 can be cooled and cooled. On the other hand, by blowing air through the air inlet 11 to the air outlet 12, the slider 1 can be powered and the movement speed of the slider 1 can be increased. Specifically, when the slider 1 slides to the front, the air outlet 12 at the front of the slider 1 can be blocked, and the air outlet 12 at the rear can be discharged. At this time, the reaction force will give the slider 1 forward power, promoting the acceleration of the slider 1; and vice versa.

[0029] Furthermore, the air outlets 12 are symmetrically arranged on both sides of the slider 1 .

[0030] In one embodiment of the present invention, reference is made to Figure 2 The upper wall of the slide groove is provided with a ventilation groove 15 along the length direction of the slider 1, and the ventilation groove 15 is connected to the air cooling channel 13.
