Whole vehicle thermal management integrator suitable for hybrid power and pure electric vehicles

Abstract

The invention discloses a whole vehicle thermal management integrator suitable for hybrid power and pure electric vehicles. The whole vehicle thermal management integrator comprises a thermal management integrated valve, a cooling fan, a bypass electromagnetic valve, a cooling module, a whole vehicle thermal management controller, an electric air conditioner, a PTC heater and pipeline accessories. The invention provides a brand-new integrated design architecture specially for a hybrid power and pure electric vehicle thermal management system, and component integration, function integration and control integration are carried out on a heat dissipation module, a heat exchange module and a heating and cooling module which are distributed in traditional thermal management. Heat exchange interconnection and intercommunication among the power battery, the electronic power device, the motor, the internal combustion engine and the cab cabin are achieved by controlling opening and closing of the electromagnetic valves, the heat balance time of the whole vehicle is shortened, and the energy use efficiency is improved. According to the integrated innovative design concept, the number of parts of the thermal management system is reduced, the overall vehicle thermal management space layout is simplified, and a brand new design architecture is provided for the design of the thermal management system of the hybrid power and pure electric vehicle.

Description

technical field [0001] The invention belongs to the field of thermal management design of new energy and energy-saving automobiles, and relates to a heat management integrator suitable for a complete vehicle of hybrid power and pure electric automobiles. Background technique [0002] Power batteries, electronic power devices and drive motors are the core components of new energy and energy-saving vehicles. The thermal management design level of the above components directly affects the driving safety and service life of vehicles. Traditional hybrid and pure electric vehicles are equipped with six sets of thermal management systems: power battery, electronic power device, motor, PTC heater, air conditioner, and internal combustion engine. Each system is independent of each other, and the pipeline layout of the vehicle is complicated and the cost of thermal management is high. [0003] At present, the waste heat utilization rate of the electric drive system of hybrid and pure ...
