| 摘 要： | 对多孔材料在低温下的传热特性进行了试验研究,试验结果表明在填充多孔材料以后夹板表面低温维持时间明显增加,主要原因是由于多孔材料的参与改变了传热特性,且材料的密度与其传热特性有着密切的关系。在一定范围内,随着多孔材料密度的增大,其传热特性不断增强。

| Abstract: | A study on heat transfer characteristic of porous material under the low temperature was introduced.The experimental result testified that the low temperature maintaining time increases obviously after filling in the porous material which changes the heat transfer characteristic.It is found that there is a consanguineous relation between heat transfer characteristic and material density.With the decrease of porous material's density,the heat transfer characteristic is enhanced continuously. |

| Keywords: | Porous material Heat transfer characteristic Material density |
