ABSTRACT:
A double cross counterflow heat exchanger of the continuous plate type is formed of a continuous sheet of heat conductive material folded upon itself on fold regions in opposite directions alternately to define a plurality of substantially parallel, mutually spaced sheet portion, substantially each sheet portion thereby being located between first and second adjacent sheet portions with the fold regions being located at the lengthwise ends of each sheet. Each sheet portion has a pair of edge sections perpendicular to the fold which joins two sheets, the portions of which edge sections, of the two sheets, most distant from the joining fold are sealed together to define a fluid flow channel, each of the channels having first and second fluid transmitting openings located at the sides of each channel, and a third fluid transmitting opening located at the end of each channel opposed to the fold sealing the opposite end of each channel.
