Abstract (en)
[origin: WO2007136379A1] A spiral flat tube heat exchanger comprising a first flat tube and a second flat tube thermally coupled to the first flat tube, the first flat tube and the second flat tube forming substantially concentric spirals. A first fluid flows through the first flat tube in a first flow direction, and second fluid flows through the second flat tube in a second flow direction. The flat tubes preferably contain microchannels to increase heat transfer efficiency.
