The heating member 91 pushes the vertical rod 92 to move, the vertical rod 92 pushes one of the heating sheets 8 to enable the heating sheet 8 to be far away from the water absorbing layer 4 opposite to the vertical rod 92, meanwhile, the vertical rod 92 moves and drives the two sliding blocks 931 to be far away from each other through the hinge rod 93, the two heating sheets 8 fixedly connected with the two sliding blocks 931 are far away from the water absorbing layer 4 on the cabinet body 1, and the function that the three heating sheets 8 on the vertical side wall of the cabinet body 1 are synchronously close to the water absorbing layer 4 or are synchronously far away from the water absorbing layer 4 is achieved.
The implementation principle of the intelligent control system of the switch cabinet in the embodiment of the application is as follows:
when the temperature of the components in the cabinet body 1 is high and the humidity of the external environment is low, the fan 2 works and sends external air into the cabinet body 1 through the first pipeline 21, so that the circulation of the air in the cabinet body 1 is accelerated, and the components in the cabinet body 1 are radiated; when the temperature of the components in the cabinet 1 is high and the humidity of the external environment is high, the fan 2 sends the external air into the dehumidifier 3 through the second pipeline 22, the dehumidifier 3 condenses the moisture in the external air into condensed water, and sends the dried air into the cabinet 1 to dissipate the heat of the cabinet 1; meanwhile, the condensed water in the dehumidifier 3 is pumped by the pump body 5 to soak the water absorbing layer 4, the water absorbing layer 4 is arranged outside the cabinet body 1, and the wet water absorbing layer 4 evaporates to absorb heat to further dissipate the heat outside the cabinet body 1.
When the temperature information of the cabinet body is smaller than the low-temperature reference temperature information, the temperature in the cabinet body 1 is too low, at the moment, the heating element 91 drives the heating sheet 8 to move to be abutted against the water absorption layer 4, the heating sheet 8 starts to work, and the outer wall of the cabinet body 1 is insulated, so that the temperature of the cabinet body 1 is not too low easily; when the cabinet temperature information is equal to the low-temperature reference information, the cabinet 1 is kept at a constant temperature by controlling the temperature of the heating sheet 8; when if cabinet body temperature information is greater than high temperature reference temperature information, heating member 91 promotes vertical pole 92 and removes, and vertical pole 92 promotes one of them heating plate 8 and makes it keep away from rather than the layer 4 that absorbs water that corresponds to, and vertical pole 92 removes and drives two sliders 931 through articulated rod 93 and keep away from each other simultaneously, and two heating plates 8 with two slider 931 fixed connection keep away from the layer 4 that absorbs water on the cabinet body 1 for the evaporation of moisture on the layer 4 that absorbs water is difficult for influencing to heating plate 8.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
