The working principle of the cooling mechanism 7 in this embodiment is as follows: in the process of pushing the connecting plate 702 to drive the cooling pipe 701 to move towards the inside of the cabinet body 2, the return spring 709 is compressed, the first positioning block 711 moves towards the second positioning block 714, the first positioning block 711 is pushed by the second positioning block 714 to rotate after being attached to the second positioning block 714, meanwhile, the rotating shaft and the end plate 712 are driven to rotate, the torsion spring 713 deforms, then the torsion spring 713 resets and drives the rotating shaft and the end plate 712 to rotate and reset, and the first positioning block 711 synchronously rotates and resets and is matched with the second positioning block 714; the interaction of the first positioning block 711 and the second positioning block 714, and the elastic force of the return spring 709 ensure the positioning of the connecting plate 702 and the cooling pipe 701, so that the positions of the first magnet block 703 and the second magnet block 705 are aligned; the first magnet block 703 and the second magnet block 705 generate mutual repulsion force, the first magnet block 703 is pushed to move upwards in the vertical section of the cooling pipe 701 under the action of the mutual repulsion force, the supporting spring 708 is stretched, and the flow of cooling water inside and outside the cabinet body 2 is promoted in the upward movement process of the first magnet block 703, so that the cooling water with higher temperature inside the cabinet body 2 enters the outside of the cabinet body 2 and exchanges heat with outside air through the cooling pipe 701, and rapid cooling is performed; meanwhile, cooling water with lower temperature outside the cabinet body 2 enters the cabinet body 2, so that the cooling effect on hot air inside the cabinet body 2 is improved.
The connecting plate 702 is continuously pushed to drive the cooling pipe 701 to face the inside of the cabinet body 2, so that the first positioning block 711 is separated from the second positioning block 714, then the connecting plate 702 is loosened after the first positioning block 711 is manually rotated, and the connecting plate 702 and the cooling pipe 701 are driven to reset through the resilience force of the reset spring 709; mutual repulsion force between the first magnet block 703 and the second magnet block 705 disappears, the first magnet block 703 moves downwards under the action of gravity and the elastic force of the supporting spring 708 for resetting, and when the first magnet block 703 moves downwards in the resetting state, the flow of cooling water inside and outside the cabinet body 2 is further promoted, so that the cooling water after heat dissipation outside the cabinet body 2 returns to the inside of the cabinet body 2 for heat absorption, and the cooling effect is further improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
