Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chassis heat dissipation, and more particularly to an independent hydraulic and electric control driven intelligent temperature control heat dissipation system. BACKGROUND

[0002] The heat dissipation system is an important part of the vehicle chassis, which realizes the cooling of the vehicle power assembly, especially for the chassis of special vehicles, considering its special purpose, it is necessary to ensure the performance stability and reliability in the extreme high temperature environment. In order to meet the requirements of high power and high mobility of the chassis of special vehicles, the chassis usually adopts a high-power power assembly, and the power system often operates under full power and high load conditions, especially the space of the chassis is relatively closed, which is easy to cause multi-source heat flow coupling interference. The traditional heat dissipation mode cannot quickly and efficiently cool the power unit, so that the power unit components are in a critical thermal load state for a long time, and the internal unit cannot be stabilized, which cannot guarantee the stable work of the chassis. In addition, for the chassis of special vehicles with limited size and rear-mounted power unit, the layout space of the heat dissipation system is limited, and the mode of directly driving the heat dissipation fan by the engine cannot be matched and installed. Therefore, for the chassis of special vehicles with high power, closed space, compact layout and rear-mounted power unit, the heat dissipation system needs to ensure quick and efficient cooling in limited installation space to maintain the thermal balance of the power system.

[0003] At present, the heat dissipation system of the chassis of special vehicles is generally driven by the engine flywheel to drive the heat dissipation fan, and the strong cold wind generated by the high-speed rotation of the fan exchanges heat with the cooling liquid flowing through the radiator. For the engine equipped with an air intake turbocharger, a intercooler is also needed to cool the pressurized air. The radiator and the intercooler are designed in a front-rear stacking manner, that is, the strong cold wind first blows through the radiator with cooling liquid, and then blows through the intercooler with pressurized air, which causes the cold wind to be heated before blowing through the intercooler, and the cooling effect of the pressurized air is reduced. Moreover, the front-rear stacking design increases the thickness of the heat dissipation module, increases the resistance of the cold wind blowing through it, and also does not have the ability to control the heat dissipation power according to the environmental conditions. Therefore, for the chassis of special vehicles with high power and closed space, the transmission heat dissipation mode cannot realize quick and efficient cooling, and for the power unit with limited size and rear-mounted, the heat dissipation fan cannot be directly installed at the tail of the engine, so that the traditional heat dissipation system is no longer suitable for the layout.
