| 摘 要： | 分析散热器传热过程及安装装饰罩对散热器传热影响的理论因素,确定散热器传热的物理及数学模型。应用FLUENT软件对未加装饰罩及安装三种装饰罩的室内空气流场进行温度场和速度场模拟,并将安装三种装饰罩后散热量与明装散热器散热量进行对比。结果表明:用于模拟的三种装饰罩中,安装隔栅型装饰罩的散热器散热量最小,安装百叶窗Ⅱ型装饰罩的散热器散热量最大,两种情况下散热量相差近15%。

| Abstract: | The thesis has analysed and discussed the heat transfer process, the effect of different covers on heat transfer process in theory. This thesis has established the rational physical and mathematical models and has simulated the steady state distribution of indoor air temperature and velocity under different radiators＇ decorative covers in virtue of the software FLUENT, has figured out the thermal out- put of radiator under three different radiators＇ decorative covers. According to the numerical results, separated fence is the worst one and window shade II is the best decorative cover . Difference of the thermal output between the two kinds of cases is nearly 15%. |
