【摘要】 通过建立太阳辐射模型，计算了不同时刻轿车各车窗表面接受的太阳直射辐射与散射辐射量．根据车室内部结构，将车室分为３４个相互独立的表面，应用积分法计算了３４个面之间的角系数，利用修正的Ｇｅｂｈａｒｔ方法，对通过窗户透入室内的太阳辐射在内表面上的分配进行了计算．求得的交换系数可用于求解包括壁面长波辐射在内的各表面之间的动态辐射换热更多还原

【Abstract】 By a model of solar radiation, the incident solar energy on car windows was calculated. According to the geometric characteristic of the car, its inner surface was distributed with 34 different parts. The Gebhart net radiation method was modified to calculate the solar energy distribution on those surfaces. The emissivity of material was taken away from the exchange coefficient, but considered as a term of radiation source. The solar energy incident on inner surfaces was computed. The Gebhart exchange coefficients were calculated to accelerate the numerical simulation of energy exchange by radiation combined with conduction of the car body and convection heat transfer inside the passenger compartment.更多还原
