Novel combined vehicle double-circulation cooling system

Abstract

The invention belongs to the technical field of vehicle cooling and heat dissipation, and discloses a novel combined vehicle double-circulation cooling system. The system is composed of a high-temperature circulating cooling system and a low-temperature circulating cooling system, a low-temperature radiator and a hydraulic oil radiator are arranged in parallel on a cooling air cooling flowing path, and then a high-temperature radiator is further arranged in a series mode on the path, so that a combined mode of arranging the radiators in the front row and the rear row is formed; the high-temperature circulating cooling system is mainly composed of an engine, an engine water pump, a transmission oil radiator and the high-temperature radiator; and the low-temperature circulating cooling system is mainly composed of the low-temperature radiator, a low-temperature circulating pump and a water-cooling intercooler. According to the system, the working temperature requirements of all the systems of a vehicle are considered, the cooling requirements of all heat sources are met, the radiators on the cooling air flowing path achieve heat exchange with cooling air in a series-parallel combination mode, the number of the radiators is reduced, the manufacturing cost of the cooling system is reduced, the cooling efficiency of the cooling air is improved, and the energy consumption of the vehicle cooling system is reduced.
