为了降低冷藏陈列柜在融霜过程中食品温度的上升和改善柜内温度场分布,设计了带有相变蓄冷材料的热管型搁架,研究其传热性能。结果发现:热管改善了蓄冷搁架前后方向的传热性能,但左右两侧温度分布不均匀。针对此问题提出了在蓄冷搁架内添加肋片进行强化传热,研究结果表明:在蓄冷搁架中添加肋片可以使搁架温度场均匀性得到改善,显著提高蓄冷搁架的蓄冷速率。 In order to reduce the food temperature in refrigerated showcases during defrosting and to improve the temperature distribution in the cabinet, a heat pipe type shelf with phase change thermal storage material was designed to study its heat transfer performance. The results show that the heat pipe improves the heat transfer performance before and after the cold storage shelf, but the temperature distribution on the left and right sides is not uniform. In order to solve this problem, it is proposed to add fins in the storage shelf to enhance the heat transfer. The results show that adding the fins in the storage shelf can improve the temperature uniformity of the shelf and significantly increase the storage cooling rate.
