Article Preview

In this paper, heat transfer model is assumed in coaxial radial heat pipe(CRHP) firstly. To verify the model , visualization and performance experiment are studied. Visualization experiments of CRHP are done under different filing radio of 20%, 30%, 35% and inclined angles of 0°(horizontal), 5°, 10°, 15°, 20°. Visualization experimental results show that CRHP of horizontal and 30% filling ratio is better on thermal characteristics. Its heat transfer model is preliminary analyzed from experimental phenomena. In performance experiment , the kind of CRHP is used to test heat transfer characteristics. The temperatures of the outside wall of outer pipe are determined and drawn diagrams. Lastly, heat transfer model is corrected anew by analyzing experimental datas.
