摘要：
A method for cleaning surfaces of a finned heat exchanger, wherein compressed air and water are used for cleaning and the compressed air is supplied to a jet nozzle (1), which has a section (7) converging to a constriction (6) and a subsequent diverging section (8), and the water or another liquid substance is fed into the flow of compressed air preferably upstream of the jet nozzle (1), or in a different embodiment upstream of, in or downstream of the constriction (6) in the jet nozzle. The jet nozzle (1) is directed at the cavity in a finned heat exchanger formed by the fins. The jet penetrates the cavity between adjacent fins for the purpose of cleaning the fin surfaces.
