چکیده:

Hydrodynamic and thermal performance of a heat pipe heat exchanger depends on a number of parameters such as heat pipe diameter, bundle geometry, orientation, fin spacing and size, etc. In this paper experimental and theoretical research has been carried out to investigate the pressure drop across tube bundle of an air to liquid thermosyphon heat pipe heat exchanger (THPHE). According to experimental data and the other methods, a new correlation for THPHE with individual finned tubes and in-line geometry has been introduced. The error of pressure drop for 40 experimental points in the new correlation is less than %15. It indicates that the new correlation possesses an acceptable accuracy in the prediction of pressure drop.
