加氢站用印刷电路板式换热器设计

Design of printed circuit heat exchangers for hydrogen refueling stations

印刷电路板式换热器基于固相增材制造扩散焊接工艺,成型产品具有耐高压、耐腐蚀、结构紧凑等优点,本文介绍加氢站用印刷电路板式换热器的设计方法,并在相同负荷条件下对比计算压缩机前氢气预冷换热器、压缩机后氢气冷却器采用印刷电路板式换热器的设计参数,结果表明:印刷电路板式换热器相对螺旋管式换热器和套管式换热器,在产品紧凑度、尺寸、质量等方面都具有优势,更符合加氢站建设需求。

Printed circuit heat exchangers are based on the diffusion welding process of solid phase additive manufacturing,and the molded products have the advantages of high pressure resistance,corrosion resistance and compact structure,The design method of printed circuit heat exchangers for hydrogen refueling stations is introduced,In addition,the design parameters of printed circuit heat exchangers for pre cooling heat exchangers of hydrogen before compressor and hydrogen coolers after compressor are calculated and compared under the same load,The results show that compared with spiral tube exchang ers and double pipe heat exchangers,printed circuit heat exchangers show significant ad vantages at the aspects of product compactness,size and weight,which can better meet the reguirements of hydrogen refueling stations.
