Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a strong hybrid electric vehicle heating system principle schematic of the present invention.(water-circulating)
Fig. 2 is coil arrangement scheme drawing in the exhaust system among the present invention.
Among the figure: 1. air-conditioning, 2. coil pipe, 3. pipe in the exhaust muffler.
The specific embodiment
Abundant for the cooling water expansion tank heating that makes the coil pipe of flowing through, the coil pipe 2 in the described exhaust system is coiled on interior 3 pipes of exhaust muffler.Cooling water expansion tank circulates in coil pipe.
In order to control the opening and closing of solenoid directional control valve accurately, be provided with temperature sensor in the described solenoid directional control valve.
Water pump is as the propulsion source of cooling-water cycle in the total system; Solenoid directional control valve play change cooling water flow to effect.
If water temperature is lower than 85 ℃, solenoid directional control valve first port closing then, promptly main cycle radiator-water box branch road is closed, cooling water flow heater via core.Coil pipe in driving engine and the exhaust system is arranged in parallel, and is communicated with water pump, solenoid directional control valve and the heater core coil pipe in flowing back to driving engine and exhaust system successively, forms water-flow circuit.If open blowing engine this moment, the cooling water expansion tank heat of then flowing through in the heater core is brought into heating in the car.
If water temperature reaches 85 ℃, then solenoid directional control valve makes the conducting of radiator-water box side branch road, and electromagnetic valve two outlets all are in conducting state, the conducting of main cycle radiator-water box branch road, and radiator-water box dispels the heat to driving engine.
Blowing engine, PTC and heater core all are in air conditioning HVAC inside.Electro heat and cooling water expansion tank heat both energy and are superimposed and can comparatively fast satisfy human body heating demand.
At circuit control system, Circuits System is made of air-conditioner controller and each sensor, and the components and parts work of being correlated with of air-conditioner controller major control a/c system sends to VMS with relevant information synchronously, the opening and closing of VMS control driving engine, and the commutation of responsible solenoid directional control valve control.
Further, for better explanation, be example with the Auto automatic operation mode of air-conditioning, this tail gas heating system principle of work and working process is described.
As depicted in figs. 1 and 2, when air-conditioning panel is in the Auto pattern, air-conditioner controller can by design temperature and indoor and outdoor temperature sensor acquisition to temperature signal judge whether to need to open PTC heating.If begin condition when precondition satisfies air-conditioning, then air-conditioner controller can send a PTC start signal to car load VMS, car load VMS is through logic determines, whether current car load condition satisfies the PTC unlocking condition, if satisfy the PTC unlocking condition then can allow car load blowing engine relay and the adhesive of PTC relay, PTC starts working.Air-conditioner controller can come internal outer circulation blender door to adjust according to design temperature and indoor and outdoor temperature sensor temperature state simultaneously.In PTC work, VMS also can send a start signal to generator set, generator set enters the generating mode of operation, water pump is started working, and the cooling water flow freeing pipe inner coil pipe of flowing through again after generator set absorbs certain heat is because the engine exhaust emission temperature is higher, the cooling water expansion tank secondary is heated in the coil pipe, after the heater core of flowing through again, heat by blowing engine bring into indoor after inflow engine once more, play the effect that promotes engine operating temperature as early as possible.
Be accompanied by the continuous rising of Engine Coolant Temperature; when the water temperature of the solenoid directional control valve of flowing through reaches 85 ℃; solenoid directional control valve two outlets all are in opening; radiator-water box direction also branch road is opened; this moment, cooling water flow was taken away heat under the effect of radiator fan and face velocity through radiator-water box; cooling water expansion tank flows back to driving engine again afterwards, plays the effect of protection driving engine.This system can make more stable the maintaining about in the of 85 ℃ of Engine Coolant Temperature by the adjusting to the electromagnetic valve aperture, can satisfy indoor occupant's heating demand more fully.Because the second use of engine exhaust tail gas comparatively fast raises Engine Coolant Temperature, can improve the effect of car load defrosting-defogging rapidly simultaneously.
Existing strong hybrid electric vehicle utilizes the PTC heating, meets the heating effect that the passenger requires in order to reach, and adopts High-Power PTC, basically about 2000 watts.Single heating, PTC work-hours length has a strong impact on the continuation of the journey mileage of car load.And the high-power electric appliance power consumption is too fast, easily causes storage battery degree of depth power shortage, influences storage battery service life.
