Embodiment Construction

[0009] The automobile cooling system provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0010] The automobile cooling system is used to remove the excess heat generated by the engine through the circulation of the engine coolant, so as to maintain the engine within the normal operating temperature range and avoid damage. The coolant circulation process of the automobile cooling system is usually divided into a large circulation and a small circulation. The small circulation refers to the circulation of the coolant only in the engine, while the large circulation refers to the circulation of the coolant between the engine and the main radiator. The existing The car cooling system usually controls the conversion of large and small cycles through a thermostat. The temperature regulating device usually includes a temperature sensing component, which opens and closes the flow of the liquid through expansion or...

Abstract

The invention provides an automobile cooling system, which comprises a main radiator (1), a controller (18), an auxiliary radiator (13), a reversing valve (10) and a temperature sensor (8), wherein an inlet of the reversing valve (10) is communicated with a water outlet (9) of the main radiator (1), a first outlet and a second outlet of the reversing valve (10) are respectively communicated to a water inlet of an engine (15) through a first pipeline and a second pipeline, the auxiliary radiator (13) is arranged on the second pipeline, the temperature sensor (8) is arranged at the water outlet (9) of the main radiator (1), and the reversing valve (10) and the temperature sensor (8) are respectively and electrically connected with the controller (18); the temperature sensor (8) is used for detecting the value of actual temperature at the water outlet (9); and the controller (18) is used for controlling the reversing valve (10) to act according to the value of the actual temperature at the water outlet (9). The automobile cooling system provided by the invention can meet the demand of higher thermal load of the entire automobile.

Description

technical field [0001] The present application relates to an automobile cooling system. Background technique [0002] Existing automobile cooling systems all realize engine cooling by radiator and fan, to ensure the normal working temperature of engine. With the promotion of new technologies in automobiles and the application of high-power engines, the automobile cooling system must not only cool the engine itself, but also bear greater heat loads, such as from automobile heaters, exhaust purification devices, hydraulic torque converters, hydraulic The heat load of other heat load generating elements such as the hydraulic retarder, especially the hydraulic retarder, generates a much greater heat load than the engine heat load during operation, and these additional heat loads require larger radiators and fans Aids in cooling. Since the matching of car radiators and fans has been basically mature, the height and thickness of radiators and fans cannot be changed much due to t...
