Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in Fig. 2 the motor vehicle warming circulatory system of the present invention includes electronic water pump, electronic water pump and gas-liquid heat-exchange
Constituted with warm air heater in circulation loop, circulation loop and be provided with coolant, electronic water pump can drive coolant to pass sequentially through
Gas-liquid heat-exchange, warm air heater simultaneously return to electronic water pump, gas-liquid heat-exchange can with high temperature motor-vehicle tail-gas occur heat exchange with
The heat of high temperature motor-vehicle tail-gas is absorbed, the heat that warm air heater is absorbed using gas-liquid heat-exchange heats for crew module.
Further, electronic water pump is connected with compensation tank, and coolant is stored in compensation tank, and coolant can be from compensation water
Case is filled into electronic water pump.Blowdown piping is provided with circulation loop, blowdown piping is preferably provided at circulation line
High point, to discharge the gas in circulation loop.
Thus, the origin of heat of crew module's heating is in the Waste Heat Recovery of motor-vehicle tail-gas, and electronic water pump can drive coolant
Circulated, by a gas-liquid heat-exchange by the heat recovery in motor-vehicle tail-gas into coolant, warm air heater utilize
The heat that coolant absorbs is heated for crew module, finally transfers heat to crew module, and the heating is circulated from engine cool system
It is independent in system, it is not necessary to rely on engine-cooling system, engine warm-up time is shortened, engine water pump is also reduced
Energy consumption.
Further, PTC auxiliary electro-heat elements are additionally provided with circulation loop, auxiliary electro-heat element and warm air heater are simultaneously
