Improvement of thermal performance of spiral heat exchanger on hydrogen storage by adding copper fins
چکیده انگلیسی

The reaction time of hydrogen in metal-hydride vessels (MHVs for short) is strongly influenced by the heat transfer from/to the hydride bed. In the present work an experimental study of the geometric and the operating parameters of a finned spiral heat exchanger has been carried out to identify their influence on the performance of the charging process of the MHV. The experimental results show that the charge time of the reactor is considerably reduced, when finned spiral heat exchanger is used. In addition, the effect of different parameters (flow mass and temperature of the cooling fluid, applied pressure of hydrogen in the case of absorption and desorption) has been discussed and obtained results show that a good choice of these parameters is important.


► The storage of hydrogen in metal hydride reactor is influenced by the heat transfer.
► The kinetic of the two reactors studied depends on the temperature and the pressure.
► The added finned spiral reduced the charge time of the reactor.
