The invention relates to a double-circulation cooling
system with an electronic
supercharger positioned in a high temperature cooling
system. The double-circulation cooling
system comprises a high temperature circulating cooling system and a low temperature circulating cooling system, wherein the high temperature circulating cooling system comprises an expansion water tank, a high temperature radiator, an engine cooling
water jacket, a first water pump, an electronic
thermostat, an engine oil cooler, the electronic
supercharger and an
air heater; and the low temperature circulating cooling system comprises an expansion water tank, a low temperature radiator, a
turbocharger, a second water pump, an
intercooler and a BSG. According to the double-circulation cooling system, the two circulating cooling systems are arranged, and the high temperature radiator and the low temperature radiator are arranged, so that the requirements of different to-be-cooled parts on the
cooling temperature are effectively guaranteed; besides, in the technical scheme, the volume of the cooling system is not increased; and in the low temperature circulating cooling system, the BSG, the
turbocharger and the
intercooler are arranged in parallel, so that the
pressure difference of the parts is guaranteed to be stable.
