a numerical and experimental investigation of flowand heat transfer in a gas- liquid thermosyphon heat
exchanger "THE" with built in heat pipes and aluminum plate fins for moderate Reynolds numbers has been
carried out.. It's module is composed of 6"rows" and 15"columns" copper pipes with aluminum plate fins with
dimensions of 130cm "height", 47cm "width" and 20cm "depth" . The tubes have been filling by water with filling
ratio of 30%, 50% and 70%. The density and thickness of fins are 300 fin/m and 0.4mm, respectively. The
configuration of tubes is in-line with 30mm pitch. This paper presents the distribution of temperature and thermal
performance of "THE" by using CFD modeling. A good comparison of the present CFD modeling results for the
modeling thermosyphon heat exchanger with experimental results of hydrodynamic and thermal behavior
achieved.
