It has high mechanical strength, toughness, good heat resistance and high thermal intensity, low shrinkage, good curing characteristics.
它具有机械强度高、韧性好、耐热性好及高的热强度、低收缩性、固化性好等特点。
The results show that the closed finned tube is much more excellent than the opening finned tube on gross heat, heat of unit volume and metal thermal intensity with the same geometric parameters.
观察发现,几何参数相同时,封闭式翅片形式在总散热量、单位体积散热量和金属热强度方面均优于开放式翅片形式。
As a result, heat dissipating capacity, metal thermal intensity and free convection heat transfer coefficient of the longitudinal closed finned tube are higher than those of the open finned tube.
结果表明,封闭式纵向翅片管的散热量、金属热强度以及自然对流换热系数都要高于开放式翅片管。
