Heat dissipation electrical cabinet for electrical automation

The invention is applicable to the field of electrical automation, and provides a heat dissipation electrical cabinet for electrical automation, which comprises a cabinet body, and further comprises acooling liquid circulation assembly used for enabling cooling liquid to circulate in the cabinet body to absorb heat in the cabinet body; a cavity; a rotor, movably arranged in the cavity and enabling the cavity to form at least two groups of dynamically closed air cavities, and the air cavities being communicated with the cooling liquid circulation assembly; an eccentric driving assembly, used for driving the rotor to eccentrically rotate in the cavity, so that the volume of each air cavity is changed, and the cooling liquid circularly circulates between the air cavities and the cooling liquid circulating assembly. The rotor rotates in the cavity in a manner of being attached to the inner wall of the cavity, the formed air cavity circularly sucks in and discharges cooling liquid, and then the cooling liquid circ
