简述铝制板翅式换热器和封头的特殊结构,分析封头的焊接设计、强度计算方法和开孔补强。提出当容器部件难以准确计算时,应先采用验证试验分析,再用对比经验设计的观点。
Briefly describe the special structure of aluminum plate-fin heat exchanger and head, analyze the head design, strength calculation method and hole reinforcement. It is suggested that when the container components are difficult to calculate accurately, we should first use the verification test analysis, and then compare the experience of the design point of view.
