The advantages are: firstly, by mounting the water pump, heating element, and outlet pipe on the bracket, the installation of these components is more convenient and the layout is neater, resulting in a compact installation of all parts; secondly, by positioning the inlet pipe and bracket on opposite sides below the water tank, the inlet and outlet components are separated, leading to a neater overall spatial layout.

This invention belongs to the field of fuel cell thermal management technology, and particularly relates to a battery cooling system and its control method based on a microtube bundle heat exchanger and countercurrent collision jet atomization. The system includes: a fuel cell stack, a microtube bundle heat exchanger connected to the fuel cell stack via a coolant circulation loop, a cathode drainage recovery unit, and a countercurrent collision jet atomization unit comprising a fan and an atomizing spray module.
