Machine room heat dissipation device

The utility model belongs to the technical field of heat dissipation devices, and particularly relates to a machine room heat dissipation device which comprises a supporting table, a shell, a protective shell and a filtering window, the shell is fixedly connected to the upper surface of the supporting table, the protective shell is fixedly connected to the upper surface of the shell, the filteringwindow is embedded in the side face of the protective shell, and a first ventilation plate is embedded in the upper surface of the shell. The utility model is advantageous in that the structure is simple, a refrigeration bin and a water pump are arranged; when people need to reduce the temperature in the shell, the temperature in the shell is reduced; when people need to cool the interior of theshell, the temperature in the shell can be lowered; people need to control the constant-temperature refrigerating element to operate through the control switch during decoration. And then people onlyneed to control the water p
