| 摘 要： | 用焓法模型建立了冷板融冰过程的数学模型，采用控制容积法对方程进行离散化，并用三对角矩阵算法求解出各节点的焓值和温度，分析了冷板厚度和车内空气温度对冷板融冰过程的影响；结果表明，冷板中心融解缓慢，冷板厚度对融冰过程影响比车内空气的影响大，减少冷板厚度将大大减少融冰时间。

| Abstract: | The mathematical model of hold-over plate during melting period was developed by using enthalpy method.The equation was discreted by using control volume method.The enthalpy and temperature of every node was calculated by using tridiagonal-matrix algorithm(TDMA).The effect of thickness of hold-over plate and temperature of indoor air towards the melting period of hold-over plate was analyzed.The results show that the ice of central hold-over plate melts slowly,the effect of thickness of hold-over plate is more than the effect of temperature of indoor air,and the discharging time will be reduced seriously by shortening the thickness of hold-over plate. |
