Cooling system for vehicle

Abstract

The invention discloses a cooling system for a vehicle. The cooling system for the vehicle comprises a high-temperature cooling loop and a low-temperature cooling loop, wherein the high-temperature cooling loop comprises an engine water jacket; a water outlet 1 of the engine water jacket is connected with a high-temperature heat radiator and a warm air core body; the high-temperature heat radiatorand the warm air core body are connected with two water inlets of an electronic thermostat; a water outlet of the electronic thermostat is connected with an inlet of a high-power electronic water pump. a water outlet of the high-power electronic water pump is connected with a water inlet of the engine water jacket; a water outlet 2 of the engine water jacket is connected with the other water inlet of the high-power electronic water pump through an engine oil cooler; a low-temperature heat dissipation loop comprises a low-power electronic water pump; a water outlet of the low-power electronicwater pump is connected with water inlets of a water-air intercooler and a turbocharger; water outlets of the water-air intercooler and the turbocharger are connected with a water inlet of a low-temperature heat radiator; and a water outlet of the low-temperature heat radiator is connected with a water inlet of the low-power electronic water pump. The cooling system for the vehicle is beneficial for increasing the temperature rise rate of an engine and reducing the pollutant emission.

Description

technical field [0001] The invention belongs to the technical field of vehicle cooling, and more specifically, the invention relates to a vehicle cooling system. Background technique [0002] As modern automotive engines adopt more compact designs and greater power per unit volume, the degree of strengthening is getting higher and higher, and the heat generated by the engine has also increased significantly. At present, all enhanced engines are faced with how to solve the cooling and heat balance problems of high power density engines. While meeting the continuously increasing power output, they must also have good economy, and the increasingly stringent emission standards have also put forward requirements on the cooling system. new requirements. [0003] The design of modern engine cooling systems has fully considered warm-up, cooling efficiency, exhaust emission control, fuel utilization, and interior heating. The working performance of the cooling system directly affec...

AI Technical Summary

Problems solved by technology

At present, there are more or less the following problems in the cooling system of existing fuel vehicles: the system is difficult to degas, and the manual filling time is longer during after-sales maintenance, especially the semi-closed structure cooling system; the cold start time of the engine is longer, which increases fuel consumption and Emission of pollutants; in the non-hot season environment, under a certain load condition, the equilibrium water temperature of the cooling system is low, resulting in a decline in the power economy of the vehicle; in the warm season environment, under severe working conditions, the equilibrium water temperature of the cooling system is high Even call the police, the deterioration of vehicle emissions has intensified, and the power economy has dropped significantly
