The invention discloses an intelligent heat dissipation method for a high and low voltage switchgear, which comprises a switchgear body. Frame, support plate, heat dissipation fins, heat dissipation pipes, water inlet pipe, water outlet pipe, the first partition, the first drying plate, the second partition, the second drying plate and the third partition, the top shell has a heat dissipation device, including Cooling fan, ventilation flexible pipe, ventilation pipe, dust-proof net, electric rod, open slot in the rear shell, beam, guide sleeve, left vertical beam, right vertical beam, lily window assembly, electric push rod in the bottom shell, upper There is a drive rack, as well as a controller and an external cooling device. The invention can take away a large amount of heat generated by the equipment through the heat dissipation pipes on the left and right sides of the shell, absorb moisture to the maximum, can generate swirling flow, avoid heat dissipation dead angles, and can intelligently adjust the angle of the louvers to realize intelligent control of water circulation.
