a numerical and experimental investigation of flow and 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.
