In a device for recuperating heat from a clothes drier, the combination of a heat exchanger with cross streams comprising a pack of facially opposed heat exchange surfaces defining therebetween a plurality of open ended channels in which a stream of a relatively cold medium - air - is passed through one set of channels in heat exchange relationship with a second air stream from a drier passing through another set of channels, such channels terminating in a surface area corresponding to the hypothenuse section of a triangular corner closed box able to catch fluid from said exchanger, the four boxes at inlets and outlets forming hermetic cells with tight joints and able to separate humid air from dry warm air and including motor means of air circulation.
