    Abstract

    This paper presents the application of CFD modelling to predict the thermal performance of a cross flow heat pipe based air to water heat exchanger. The investigated heat exchanger is equipped with six wickless water-charged heat pipes with a single pass flow pattern on the air side and two flow passes on the water side. For the purpose of CFD modelling, the heat pipes were considered as solid devices of a known thermal conductivity, which is estimated from comprehensive experimental investigation on these heat pipes under the whole testing range. The CFD results were validated using a full scale system and it was found that the modelling predictions are within 10% of the experimental results.
