Summary

The effective thermal conductivity of metal hydride (MH) alloy bed being extremely low (about 1 W/m.K), adding carbon fibre to the MH bed is used to enhance the heat transfer performance. In addition, it is clear that the effective thermal conductivity of MH-2 alloy bed is higher than that of MH-1 alloy. The effective thermal conductivity of the MH alloy bed with and without carbon fibre was measured and compared. Adding carbon fibre is useful method for MH alloy's heat transfer enhancement. The effects of driving conditions, heat source temperature, middle cooling temperature and initial system equilibrium pressure are also discussed. Finally, using the above calculation model, the influence of the addition of carbon fibre on the refrigeration performance is analysed. (see also Bulletin of the IIR, ref. 2000-0745 and 2001-2750).
