The invention relates to an integrated reactor module. In the integrated reactor module, a shell and a base hold a reactor and a cooling fan therein and a cooling air channel is formed around the reactor. The integrated reactor module has the structure that: the reactor is fixedly arranged on the base; the bottom of the shell is connected with the base through a fixing supporting foot; radiating vents are arranged on the shell above the reactor; a cooling fan is arranged in the shell above the reactor and corresponding to the radiating vents; the terminal of the reactor and the power terminal of the cooling fan are arranged on the shell; lead wires in the reactor and the cooling fan are correspondingly connected with external circuits through the terminals; a circle of radiating vents are arranged at the combined part between the bottom of the shell and the base; and a radiating air channel is arranged between the reactor and the inner wall of the shell around the reactor.
