摘要
随着新型绝热材料的研究及应用,防护热板装置已广泛用于测量各个领域绝热材料的导热系数,从航天到化工、从能源到建筑,防护热板装置都发挥着重要的作用。总结了防护热板装置国内外的最新研究进展;探讨了在低温液体贮存和运输领域,防护热板装置测量的技术问题及应用前景。
with the rapid development and applicaion of new thermal insultions, the guarded hot plate apparatus for the measurement of themal insuhions was received more attention in fields of aerospace, chemical engineering, thermal science and architectural engineering. The recent progress on different kinds of guarded hot plate apparatus was first reviewed. The guarded hot plate apparatus operating down to liquid nitrogen temperature（ - 196℃ ） was proposed to measure the the thermal conductivities of thermal insulations, which were used for cryogenic liquid storage and transport. The design and construction of the guarded hot plate apparatus were also introduced.
