Technical Field

The invention relates to a heat management system of a new energy automobile, in particular to a flushing-resistant efficient water air intercooler suitable for a hydrogen fuel automobile.

Background

The hydrogen fuel cell converts chemical energy into electrical energy through a catalytic oxidation reaction of hydrogen and oxygen, and generates water without any pollution. The hydrogen fuel cell has the characteristics of cleanness, high efficiency, no pollution, high energy efficiency, high reliability and the like, and the source of the hydrogen is relatively wide, so that the hydrogen fuel cell is an ideal power source with the optimal potential in the future.

The water-air intercooler of a hydrogen fuel automobile is a heat exchanger which cools pressurized air entering a fuel cell stack through cooling liquid consisting of ethylene glycol and water. Because the hydrogen fuel electric pile has high temperature sensitivity, the temperature of the pressurized air entering the electric pile is generally required to be less than 80 ℃, and meanwhile, the energy loss of the pressurized air has high requirement, so that a water air cooler of a hydrogen fuel automobile is required to have high heat exchange quantity and low air side resistance. Besides meeting the heat exchange requirement, ions separated out from the intercooler can influence the insulation resistance of a power system and the service life of the deionizer, and the water-air intercooler of the hydrogen fuel automobile is required to have very low ion separation rate. Ions can be continuously separated out at a welding seam generally, and the separated ions need to be washed by using cleaning equipment, so that the conductivity of a product after loading is ensured.
