摘　　要：通过建立热管的简化热阻模型,采用数值计算的方法模拟了热管的动态蓄冰。模拟结果与实验结果吻合。同时,对热管冷凝段和蒸发段的长度比为1:2和1:4两种形式进行了数值模拟比较。结果表明,1:4的布置形式更优。Based on thermal resistance model of heat pipe, numerical simulation is done to study ice cold storage process using heat pipe. Experimental data of temperature is compared with simulation＇ s. The results show that they are agreed well. Meanwhile, two heat pipes which has different length proportions of condensing section and evaporating section are investigated during simulation of freezing process. It is concluded that the heat pipe which proportion is 1：4 behaves better than the heat pipe which proportion is 1：2.
