Problems solved by technology

[0003] Once the design is frozen, under the same working condition, the flow distribution of each branch is fixed and cannot be distributed according to demand. The increase or decrease of the flow of each branch is mainly controlled by the speed of the pump at the same time, and the relationship with the temperature is only It is adjusted by the change of the speed of the water pump. The low speed of the water pump cannot achieve large flow, and the high speed will generate redundant large flow and cause energy loss.

Abstract

The invention discloses a vehicle cooling system which comprises a radiator, a cylinder body, a cylinder cover, a flow control structure, a heater water return pipeline, an oil cooler water return pipeline, a cooler water return pipeline and a water pump. The flow control structure comprises a water temperature sensor, a control structure body and a main valve structure. According to the vehicle cooling system, the water temperature sensor sends water temperature signals of the heater water return pipeline, the oil cooler water return pipeline, the cooler water return pipeline and a water inlet pipeline of the radiator to the control structure body in time, and according to the water temperature signals, the control structure body flexibly controls the main valve structure to open or close all the pipelines, so that the situation that water flow branch flows in all the pipelines are flexibly controlled is realized, overall on-demand deployment is realized, and unnecessary energy consumption losses are avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle cooling, in particular to a vehicle cooling system. Background technique [0002] The distribution of the traditional cooling system is realized by fixed structural pipelines. In related systems, a double-valve thermostat is generally used to control the large cycle (connected to the radiator branch) and the small cycle (water pump-cylinder block-cylinder head-water pump). The oil cooler, exhaust gas recirculation (EGR) cooler, and front and rear heating air branches are all in a normally open state. Usually, the internal pipe diameter of each branch is designed based on the results of fluid analysis. [0003] Once the design is frozen, under the same working condition, the flow distribution of each branch is fixed and cannot be distributed according to demand. The increase or decrease of the flow of each branch is mainly controlled by the speed of the pump at the same time, and the relationship w...
