摘　　要：管翅式冷凝器做为冷藏陈列柜中制冷系统的关键部件,其主要的发展方向是轻量化、紧凑化、小型化。本文采用5mm小管径铜管替代原有9.52 mm铜管,并对其结构参数进行优化设计,设计了两款小管径冷凝器。通过数值模拟计算两个小管径冷凝器和传统大管径冷凝器在不同工况条件下的换热量和压降。计算结果表明:小管径冷凝器2表现提升显著,换热量相较于原有冷凝器平均提升了16%~47%,压力降下降了34%~38%,相较于原有冷凝器有较大提升,验证了利用小管径替代技术实现对冷藏陈列冷凝器的优化及应用是可行的。As the key component of the refrigeration system in the refrigerated display cabinet, the main development direction of the tube fin condenser is lightweight, compact and miniaturization. In this paper, 5mm small-diameter copper tube is used to replace the original 9.52 mm copper tube, and its structural parameters are optimized. Two small-diameter condensers are designed.Through numerical simulation, the heat exchange and pressure drop of two small-diameter condensers and traditional large-diameter condensers under different working conditions are calculated. The calculation results show that the performance of small diameter condenser 2 is significantly improved, the average heat exchange is increased by 16%~47% compared with the original condenser,and the pressure drop is reduced by 34%~38%. Compared with the original condenser, it is greatly improved, which verifies that it is feasible to realize the optimization and Application of refrigerated display condenser by using small diameter substitution technology.
