An insertable contact body for one medium or several media, e.g. for heat exchangers, cooling towers, scrubbers or the like, which body is composed of sheets (10, 12; 20, 22; 28; 32) provided with folds or corrugations. The sheets are arranged adjacent one another in such a manner that the folds in adjacent sheets extend angularly relative one another. The sheets are arranged at a distance from one another, whereby a major part of those folds which form an angle with each other are separated from one another by an interspace between their crest without the same bearing against one another. This is preferably accomplished by means of distance members (18; 24; 30; 34), by which the sheets are kept at the said distance.

Insertable contact body

In an evaporative cooler having a casing, a multi-layer type contact body and means for supplying water to selected channels in the contact body, the top edges of the contact body are formed to define outwardly widened openings communicating with only selected channels in the body. The water supply means supplies water to only some of the openings so that alternating channels on the contact body are passed with both water and air and the remainder only with air. As a result the formation of mist at the discharge end of the cooler can be avoided.
