The invention discloses a multiparameter coupling droplet evaporation experiment channel. The channel is circular and comprises a fan section, a temperature adjustment section, a pressurization section, a flow adjusting section, a flow stabilizing section and an experimental section which are sequentially connected end to end, and an operation console, a heater and a radiation determinator are arranged in a test section. Compared with the prior art, the channel disclosed by the invention has the advantages that a fan, a heating wire and a booster pump are respectively connected with a controlsystem, power of the fan, the heating wire and the fan is controlled by virtue of a signal of an acquirer, and realization of stable states of wind speed, temperature and pressure in an evaporation chamber can be facilitated; the radiation determinator is mounted on a lifting operation console and at the same height with the lifting operation console, and radiation degree change in an evaporationprocess can be determined; a flow adjusting grating is arranged at a bend, so that airflow disturbance in the channel is smaller; a flow adjusting layer is arranged in the flow adjusting section, so that inlet air of the experimental section is more uniform; and a glass window is arranged in the outer wall of the evaporation chamber, and droplet form change in the evaporation process can be monitored in real time.
