SOFC热管理系统高温换热器解决方案

随着能源的日趋枯竭和环境恶化，高效、清洁的新型能源开发与利用将成为21世纪能源发展的重要选择，固体氧化物燃料电池(SOFC)是一种将燃料与氧化剂中的化学能直接转换成电能的全固态电化学发电装置，能量转换效率高，可达到60%左右，产生的热进行热电联供效率可达到80%以上，是目前最为前沿、也是技术难度最高的新燃料电池，世界上发达国家普遍把它作为一种战略储备技术。沈氏节能研制的FPHE系印刷板式微通道换热器在SOFC和SOEC系统上的应用已有众多落地案例，近几年公司持续在此领域发力，打磨产品质量，扩大市场占比。

沈氏节能和潍柴合作，研发了船用钛合金中冷器，并应用于船舶动力系统。沈氏节能研发的钛合金中冷器采用板翅式结构，换热器芯体使用真空扩散焊接的方法成型，其原理是将若干层不同厚度的金属薄板经过流道和外形加工后，在真空状态下施加适当的压力与温度，使金属表面充分结合。用这种焊接方法制造的芯体具有无接头、无焊缝、无任何其他类型的潜在故障点等优势，其焊接后的强度，更是能达到母材的95%以上，保障产品的卓越性能。
