Description

technical field [0001] The invention belongs to the technical field of fuel cell cooling circuit testing, and more particularly relates to a cooling circuit testing device for automobile fuel cells. Background technique [0002] Vehicle fuel cells must maintain low conductivity of their cooling circuits during operation. Excessive cooling liquid conductivity will lead to a series of problems such as vehicle insulation failure and fuel cell efficiency reduction, resulting in fuel cells and the vehicle cannot operate normally. produce a greater security risk. It is therefore crucial to test the ion extraction in the fuel cell cooling circuit and treat it accordingly. At the same time, different from the design requirements of the heat dissipation module of ordinary fuel vehicles and electric vehicles, in order to ensure the stable and efficient operation of the fuel cell system, the vehicle fuel cell heat dissipation module not only needs to consider its heat dissipation capa...
