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.
