Abstract
A room ventilator structured to define therethrough both a primary airstream and a secondary airstream arranged in heat exchange relationship with each other. A heat exchanger located to have both said primary and secondary airstreams flow therethrough is structured to divide both of said streams into numerous smaller partial airstreams with walls made of high thermal conductivity intermediate the partial airstreams to enhance the heat exchange capacity between the streams. The heat exchanger is designed so that it may be installed in the ventilator in a plurality of reversed positions without impairing its function.
