    摘要: The present invention discloses an impactor with a cooled impaction plate capable of efficiently separating aerosols by cooling the impaction plate below a temperature of fluid inflowing into the impactor and a method for classifying and collecting the aerosols using the same. The impactor with a cooled impaction plate according to the present invention comprises: an accelerating nozzle for accelerating movement of the aerosols; an impaction plate for changing the flowing direction of the aerosols by means of impacting the aerosols exhausted from the accelerating nozzle, and for collecting the aerosols which are out of the flowing path of the aerosols and have larger inertia than critical value, wherein the impaction plate is installed apart from an outlet of the accelerating nozzle; and cooling means for cooling the impaction plate below a temperature of fluid inflowing into the impactor, wherein the cooling means is fixedly installed at the impaction plate.
