摘要
针对氢燃料电池汽车在运行过程中排放热量多、散热系统体积大等问题,设计并搭建了模拟氢燃料电池散热系统的实验测试装置,采用相变介质HFE-7100作为系统循环工质,研究流道布局和流程数对平行流冷凝器散热量和压降的影响。结果表明:在相同流程数条件下,流道布局采用非对称布局4流程(12-9-7-4)平行流冷凝器的散热性能优于对称布局4流程(8-8-8-8)结构,而在非对称布局条件下,采用3流程(15-11-6)平行流冷凝器的散热性能优于4流程(12-9-7-4)结构。总体而言,采用非对称布局3流程(15-11-6)的平行流冷凝器更适合氢燃料电池散热系统。
Aiming at the problems of much heat emission and large volume of cooling system during the operation of hydrogen fuel cell vehicle,an experimental test device simulating the cooling system of hydrogen fuel cell was designed and constructed,and the phase change medium HFE-7100 was used as the circulating medium of the system to investigate the effects of flow channel layout and flow path number on heat dissipation and pressure drop of the parallel flow condenser.The results show that,under the condition of the same number of flow paths,the cooling performance of the parallel flow condenser with asymmetric layout 4-flow(12-9-7-4)is better than that of the symmetric layout 4-flow(8-8-8-8)structure,whereas under the condition of asymmetric layout,the cooling performance of the parallel flow condenser with 3-flow(15-11-6)is better than that of the 4-flow(12-9-7-4)structure.Overall,the parallel flow condenser with an asymmetric layout 3-process(15-11-6)is more suitable for the hydrogen fuel cell cooling system.
