Zusammenfassung: | The compatibility of Ba(OH)2?8H2O with aluminum alloy and copper after 50
heating cycles was studied using SEM and high power X-ray diffraction
technique. Analyze the effect of temperature on thermal stability. The
results show that Ba(OH)2?8H2O has some corrosion resistance to aluminum
alloys and is similar with copper. The Ba(OH)2?8H2O/foam copper phase
transition composites were prepared by a simple vacuum adsorption filling
method. The experimental process of phase change energy storage device with
and without copper foam was established, and the continuous heat transfer
and transformation of Ba(OH)2?8H2O/foam copper phase change composites were
carried out at room temperature. The results show that compared with pure
Ba(OH)2?8H2O, Ba(OH)2?8H2O/foam copper phase converter has faster heat
transfer and better thermal conductivity, effectively reducing the
supercooling effect of Ba(OH)2?8H2O. Heat transfer experiment at high
temperature shows that the heat capacity of Ba(OH)2?8H2O/foam copper phase
changes with the increase of temperature. When the temperature of the zone
is higher than the material phase changes in temperature, some insulation
measures should be taken for phase shifting components. |
