The novel external large-air-volume fan comprises a second fixing frame, supporting frames are symmetrically installed in the second fixing frame, a driving motor is fixedly installed at the end, away from the second fixing frame, of each supporting frame, and a supporting plate is fixedly installed on the upper surface of each driving motor. The upper end of the supporting plate is fixedly connected with a condensation pipe, one end of the condensation pipe is fixedly connected with a water inlet pipe, the water inlet pipe penetrates through the second fixing frame, extends out of the second fixing frame and is fixedly connected with a rainwater collecting box, a filtering pipe is fixedly installed on the rainwater collecting box, and a collecting hopper is fixedly installed on the upper surface of the filtering pipe. After rainwater is collected, the rainwater is used for cooling the fan, the service life of the fan is prolonged, and the resource utilization rate is increased. 本实用新型公开了风机技术领域的一种新型外置大风量风机，包括第
