摘要
从理论上对空心砌块的传热过程进行了研究 ,指出它内部存在两种传热方式 :交界面附近区域是对称二维温度场 ,该域内既有壁面温差方向的传热又有上下之间相互转换的对称传热。在非交界面附近区域内是一维温度场下的传热。鉴于整个砌块传热的复杂性 ,其当量导热热阻只有测试才行。另外 ,又从提高砌块隔热保温效果出发 。
A theoretical study of process of heat transformation of hollow masonry block is presented,it is pointed out its two internal ways of heat transformation:one is that there is a symmetric two\|dimensional temperature field near the boundary area in which there is heat transformation in the direction of difference in temperature as well as symmetric heat transformation happening between two sides,the other is that there is heat transformation in a one\|dimensional temperature field in the non\|boundary area.Because of the complexity of heat transformation of the entire masonry block,its equivalent conductible heat resistance can only be acquired by testing.The correct ways of drilling holes and utilization with the aim of increasing the effect of heat insulation and preservation of masonry block is also given here.
