摘要
分别从改变翅片厚度和换热管规格2个方面对翅片式换热盘管整体换热性能和成本的影响进行分析和实验研究。结果表明,只减小翅片厚度或减小换热管规格均会导致换热器的整体换热性能下降,若保持相同换热量,则可能需要用更多的换热原材料,而这会导致换热器成本的增加。
The influence of changing the thickness of fin ＆ the diameter of heat exchanger tube on heat transfer performance and its cost is analyzed and tested. The result shows that just reducing the thickness of fin or the diameter of heat exchanger will decrease the whole performance of the heat exchanger. It needs more the heat exchanger material to keep the heat transfer rate which will increase the cost of the heat exchanger.
