【Abstract】 Describes the construction of vacuum plate insulator and its characteristics,the thickness distribution of the vacuum plate insulator used in the BCD-186 CHS fridge we developed and the composition of composite insulator by which the vacuum plate is made to combine with polyurethane.Then,the insulating properties of polyurethane is conpared with that of composite insulator,such as heat leakage and energy consnmption,when they are applied to the fridge developed.Testing results showed that the heat leakage can be decreased by 12.6% with energy cnsumption decreased by 11.4% if using the composite insulator.Introduces the way to apply the vacuum plate insulator to the thermal insulation of fridge,relevant precautions and its effect.Looks ahead to the applications of the vacuum plate insulator.更多还原
