The invention discloses a cooling system and related components of a hydrogen fuel cell, and relates to the field of heat dissipation, and the cooling system is characterized in that a heat exchanger vaporizes liquid hydrogen input from a liquid hydrogen storage device at a first input end into gaseous hydrogen and outputs the gaseous hydrogen to a third pipeline; cooling the cooling liquid in the first pipeline based on the heat absorbed in the vaporization conversion process and outputting the cooling liquid to the second pipeline; the first pipeline is used for conveying cooling liquid after the hydrogen fuel cell is cooled; the second pipeline is used for conveying the cooling liquid cooled in the heat exchanger so as to dissipate heat of the hydrogen fuel cell; the third pipeline transmits gaseous hydrogen to the hydrogen fuel cell; and the cooling device is used for carrying out secondary cooling on the cooling liquid in the second pipeline. The heat dissipation process is divided into two parts, in the heat exchanger, liquid hydrogen is vaporized into gaseous hydrogen to take away a part of heat, and cooling liquid is cooled; the cooling device conducts secondary heat dissipation on the cooling liquid passing through the heat exchanger, the working power of the cooling device is reduced, and then working noise and energy consumption are reduced.

    本发明公开了一种氢燃料电池的冷却系统及相关组件,涉及散热领域,包括:换热器将第一输入端由液氢存储装置输入的液态氢汽化为气态氢输出至第三管道,基于汽化转换过程中吸收的热量将第一管道中的冷却液降温并输出至第二管道;第一管道传输为氢燃料电池降温后的冷却液;第二管道传输在换热器中降温后的冷却液,以为氢燃料电池散热;第三管道传输气态氢至氢燃料电池;冷却装置对第二管道中的冷却液进行二次降温。将散热的过程分为两部分,在换热器中由于液态氢汽化为气态氢会带走一部分热量,对冷却液降温;冷却装置对经过换热器的冷却液进行二次散热,对于冷却装置本身降低了工作功率,进而降低了工作噪声和能耗。
