Radiating system of vehicle matching hydraulic retarder and vehicle

Abstract

The invention provides a radiating system of a vehicle matching hydraulic retarder, which comprises an engine and a cooling loop system connected with an engine cooling channel; a hydraulic retarder is arranged on the cooling loop system; a water outlet pipe of the hydraulic retarder is linked with an assistant cooling pipeline in parallel, and a control module for controlling its conduction is arranged on the assistant cooling pipeline when the water effluent temperature of the hydraulic retarder exceeds a preset value. The assistant cooling pipeline is linked to the water outlet pipe of thehydraulic retarder in parallel, and water temperature is monitored by the control module; when the monitored effluent temperature exceeds the preset value, the assistant cooling pipeline is conducted,thus the assistant cooling pipeline is connected to the cooling loop system to cool together, the cooling ability of the vehicle radiating system is improved, and the cooling requirement of the vehicle cooling system is satisfied. The invention further provides a vehicle.

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...

AI Technical Summary

Problems solved by technology

However, the vehicle cooling system cannot meet the heat dissipation requirements, and it is necessary to increase the heat dissipation capacity of the vehicle cooling system. Generally, the ways to increase the heat dissipation capacity of the vehicle cooling system include increasing the diameter of the fan, increasing the heat dissipation area of ​​the water tank, or increasing the water flow of the cooling system Wait

[0004] However, due to the limitation of the engine room of the whole vehicle, the increase of the fan and the water tank is small, and the increase of the water flow will not improve the heat dissipation capacity of the cooling system, and it will increase the fuel consumption of the engine.
