Embodiment Construction

[0042] see figure 1, the heat management system 100 of the hybrid vehicle of the present invention is mainly composed of the engine water circulation system, the motor transmission module oil cooling circulation system and the motor cooling circulation system. Wherein, engine 11 is installed in the engine water circulation system, and engine water circulation system is used for absorbing the heat that engine 11 produces, and engine water circulation system makes use of engine 11 high calorific value, makes the water temperature in engine water circulation system rise rapidly. The oil cooling circulation system of the motor transmission module is connected with the engine water circulation system. After the engine water circulation system absorbs heat, the water temperature rises to heat the oil in the oil cooling circulation system of the motor transmission module, so that the temperature of the oil in the oil cooling circulation system of the motor transmission module increase...

Abstract

The invention provides a heat management system of a hybrid vehicle and the hybrid vehicle. The heat management system of the hybrid vehicle comprises an engine water circulation system, a motor transmission module oil cooling circulation system and a motor cooling circulation system, wherein the engine water circulation system is used for absorbing heat generated by an engine of the vehicle; the motor transmission module oil cooling circulation system communicates with the engine water circulation system to heat an oil liquid in the motor transmission module oil cooling circulation system by using the engine water circulation system; the motor cooling circulation system communicates with the motor transmission module oil cooling circulation system; and the motor cooling circulation system is used for controlling the value of the temperature of the oil liquid in the motor transmission module oil cooling circulation system. According to the heat management system of the hybrid vehicle, by using the engine water circulation system to heat the oil liquid in the motor transmission module oil cooling circulation system, the temperature of the oil liquid is increased, the viscosity of the oil liquid is reduced, and the friction power of the motor transmission module oil cooling circulation system is reduced, and therefore, the oil consumption of the whole vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a thermal management system of a hybrid vehicle and a hybrid vehicle with the thermal management system. Background technique [0002] At present, for the range-extending hybrid electric vehicles, the REDS (motor-transmission module) assembly, which uses the integrated design of the generator, drive motor and transmission module, is combined with the engine to form a range-extender module, and the REDS system adopts an integrated The oil-cooled design greatly improves the power density, which is conducive to the layout of the range extender and the reduction of cost. [0003] However, under low temperature conditions, the REDS system with integrated oil cooling design will increase the fuel consumption of the vehicle due to the low temperature of the engine oil, resulting in high friction work of the REDS system. Contents of the invention [0004] An object of the present inv...
