空心环支承菱形翅片管油冷凝器传热性能

Investigation on heat transfer performance of oil condenser with lozenge fin tubes supported by rings

以柴油蒸气为工质,通过对比试验,研究1种壳程结构采用空心环管间支承的新型油冷凝器的传热性能,得到了2种油冷凝器的总传热系数和壳侧冷凝对流传热系数随热负荷变化的关系曲线。在本实验研究的条件范围内,空心环支承菱形翅片管油冷凝器具有较好的冷凝传热效果。

?Taking diesel oil vapor as work fluid,condensing performance of a new oil condenser has been investigated through experiments.Experimental results indicate that condenser with lozenge fin tubes supported by rings shows satisfactory condensing heat transfer characteristics and has a splendid future when applied in petroleum industry.
