Abstract

The invention provides a heat dissipation system for a complete vehicle matching a hydraulic retarder, comprising an engine and a cooling circuit system connected to a cooling channel of the engine, the cooling circuit system is provided with a hydraulic retarder; the outlet pipe of the hydraulic retarder An auxiliary cooling pipeline is connected in parallel on the upper side, and a control module for controlling the conduction of the hydraulic retarder when the outlet water temperature of the hydraulic retarder exceeds a predetermined value is arranged on the auxiliary cooling pipeline. The outlet pipe of the hydraulic retarder is connected in parallel with the auxiliary cooling pipeline, and the control module monitors the water temperature, and when the monitored outlet water temperature exceeds a predetermined value, the auxiliary cooling pipeline is turned on, so that the auxiliary cooling pipeline intervenes in the cooling In the loop system, the cooling work is performed together, thereby improving the cooling capacity of the vehicle cooling system and meeting the cooling requirements of the vehicle cooling system. The invention also provides an automobile.

Description

technical field [0001] The invention relates to the technical field of engine cooling systems, and more specifically, relates to a cooling system for a complete vehicle matching a hydraulic retarder and an automobile. Background technique [0002] The hydraulic retarder is a kind of automobile retarder that reduces the speed of the vehicle through a hydraulic device. It is a device that uses liquid damping to produce the retarder effect. [0003] At present, the hydraulic retarder of the whole vehicle will not have high water temperature under the condition of climbing and heavy load, but it is easy to have high water temperature when the hydraulic retarder is turned on when going downhill. Factors such as the vehicle weight, when the hydraulic retarder is turned on, the energy is converted from mechanical energy into thermal energy, and the thermal energy is then taken away through the cooling system. However, the vehicle cooling system cannot meet the heat dissipation req...
