PROBLEM TO BE SOLVED: To provide a small heat exchanger requiring no power for recovering heat from fluid without pressure such as hot waste water. SOLUTION: A falling liquid film is formed outside a horizontal heat transfer tube to increase heat transfer rate. A straightening vane is provided so as to prevent invalid droplets generated when the horizontal heat transfer tubes are combined in a multi-stage manner. COPYRIGHT: (C)2011,JPO&INPIT
