Summary

An attempt to mix carbon fiber and a metal hydride (MH) bed was discussed, to enhance the heat transfer performance of a pure MH bed heat exchanger. The effective thermal conductivity of MH bed with and without carbon fiber was measured using an unsteady state method and compared. As the best result, 3 per cent mass mixing carbon fiber data exhibited conductivity that was 4 times larger than that of the pure MH bed. Finally, the simple refrigerator model was modified and the influence of adding the carbon fiber on the real refrigeration effect was analyzed by using a numerical calculation.
