| 车载蓄冷板是充冷式冷藏车的重要组成部分,缩短蓄冷板充冷时间对提高冷链物流的效率具有重要作用。本文提出了一种热管换热蓄冷板,模拟研究了蓄冷板充冷冻结过程,并通过实验研究进行了对比分析,验证了理论模型的可靠性。利用正交试验方法研究了热管管径、管间距、通道内载冷剂流速以及雷诺数对蓄冷板充冷性能的影响。结果表明,常规单层厚度为50mm左右蓄冷板,热管管径7mm、管间距39mm、通道内载冷剂流速1.2m/s、雷诺数3.89为最优参数。将最优参数下的导换热的蓄冷板的充冷性能与相关文献报道的结果相对比,蓄冷板的充冷时间大大缩短。 |

| Abstract: |
| The vehicle mounted cold storage plate is an important part of a refrigerated vehicle, and shortening the charging time of the cold storage plate plays an important role in improving the efficiency of cold chain logistics. This study proposes a heat pipe heat exchange and cold storage plate, and simulates the freezing performance of the cold storage plate, such as the freezing time. Through experimental research and comparative analysis, the reliability of the theoretical model is verified. The influence of heat pipe diameter, tube spacing, refrigerant channel flow rate and refrigerant channel Reynolds number on the charging performance of the cold storage plate was studied by orthogonal test method. The results show that the optimal diameter of the heat pipe of the cold storage plate is 7 mm, the tube spacing is 39 mm, the flow rate of the refrigerant channel is 1.2 m/s, and the Reynolds number of the refrigerant channel is 3.89. Comparing the freezing performance of the thermal storage plate under the optimal structure with the results reported in relevant literature, the freezing time of the thermal storage plate has been significantly shortened. |
