The invention belongs to the technical field of internet information, and particularly relates to an internet information service management system which comprises a server cabinet, a cabinet door is hinged to the server cabinet through a hinge, a handle is fixedly connected to the cabinet door, and four rectangular openings are formed in the server cabinet; through the structural design of the cooling heat dissipation cabinet, when a temperature sensor in the server cabinet senses that the temperature in the server cabinet is high, the temperature sensor transmits information to a PLC, the PLC starts a first fan and opens a first electromagnetic valve, the first fan blows air into a first shell, the air enters a water tank through a first L-shaped pipe, and the temperature in the server cabinet is lowered. A large amount of water is contained in the water tank, the water cools incoming air, the air becomes cold air, and the cold air is blown into the server cabinet through the rectangular opening and the filter screen plate to cool and dissipate heat in the server cabinet, so that the function of quickly cooling and dissipating heat in the server cabinet is realized.
