Abstract

The invention relates to the field of engineering machinery, and discloses a vehicle cooling system, a control device and a control method of the vehicle cooling system, and engineering machinery. The vehicle cooling system comprises a heat radiator, a first fan, a second fan, an engine cooling pipeline and a hydrodynamic retarder cooling pipeline, wherein the first fan is arranged in a first cooling area of the heat radiator; the second fan is arranged in a second cooling area of the heat radiator; the engine cooling pipeline is connected with the hydrodynamic retarder cooling pipe to form a cooling loop; and the cooling loop is provided with a cooling liquid outlet and a cooling liquid inlet which are respectively communicated with the outlet end and the inlet end of the heat radiator. Compared with the prior art, the cooling effect of the vehicle cooling system can meet cooling requirements under different situations, so that the cooling ability of the system can be guaranteed, the cooling efficiency of the system is improved, and unnecessary energy waste is avoided; in addition, the vehicle cooling system is low in cost and occupies a small space.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a heat dissipation system for a vehicle, a control device and a control method thereof, and an engineering machinery. Background technique [0002] Hydraulic retarder is also called hydraulic deceleration device. Cars use exhaust brake when going down a long slope. Although they can receive a good braking effect, for construction machinery such as cranes with a large tonnage, the effect of using exhaust brake is relatively limited. Therefore, in order to improve braking performance and ensure driving safety, hydraulic retarders are generally installed on large-tonnage construction machinery. [0003] The original cooling system for getting off the car mainly ensures the cooling effect of the engine, but after the hydraulic retarder is installed, because the hydraulic retarder generates a lot of heat during the working process, in order to ensure the normal operation of the h...
