Embodiment
The type of automobile warm-air source consumption new energy is researched and developed, is diversified.Wherein electric energy is changed into using solar energy
Or it is the new technology developed rapidly in the recent period again that heat energy, which is used for warm wind source,.Heavy caliber solar energy heat collection pipe（Generally use glass material
Matter, more than bore φ 100mm）One of technical characteristic be that it can work under horizontal positioned state, to angle of incidence of sunlight
Degree does not require that this just creates condition for its application on all kinds of pure electric automobiles too much.To a certain specific region, when
Between, the irradiation energy of sunshine is and to be sunlighted the receptor area of thing directly proportional.Every automobile has one closely
The roof of horizontal plane, it is different and different with the type of car that it is sunlighted area.The area of sedan is minimum, bus and
All kinds of van areas are larger, high using degree.But sunshine per unit area irradiation energy be it is limited, though bus
So there is very big daylighting area, but in-car space of taking is big, Cheng Yuanduo；It is also more to the demand of warm wind amount；And van（Except spy
Outside kind vehicle such as refrigerator car）Existing larger roof area, cab space but very little, can be by more heavy caliber solar energy collection
Caused heat concentrates on a relatively small space and used after heat pipe parallel connection, is that more satisfactory one kind can apply vehicle.
The embodiment of electric automobile in the utility model：As depicted in figs. 1 and 2, the electric automobile includes car body and thereon
The heating installation of setting, heating installation include along liquid medium flow direction be sequentially connected and formed loop be used for lie in a horizontal plane in car
The solar thermal collector on top, for heat in liquid medium to be changed to the warm air radiator 8 into air-flow, for driving liquid to be situated between

Speed controls by controller 11, heat-exchanger pump 6 and controller 11 itself power consumption 100W or so, only accounts for the 1/ of the energy consumption of electric heater 7
10.When every morning, vehicle brought into operation, residual temperature when water temperature is vehicle lay-off yesterday in heavy caliber solar energy heat collection pipe 9, lead to
Very close to ambient air temperature.Now the water in thermal-collecting tube 9 is in minimum.With the irradiation of sunshine, heavy caliber solar energy heating
Pipe 9 will soon make water few in pipe be rapidly heated, before the preset temperature of warm air radiator 8 is not reaching to, electrical heating
Device 7, with the collective effect of heavy caliber solar energy heat collection pipe 9, makes water in system heat up still in heating with full power state.Controller 11
By the output signal of temperature detector 5, water temperature in warm air radiator 8 is perceived at any time, with the rise of water temperature in system, is gradually reduced electricity
The power of heater 7 or heat time, until stopping electrical heating.After electric heater 7 is stopped, in heavy caliber solar energy heat collection pipe
Under 9 effects, if water temperature continues to rise in system, instruction is sent under the effect of controller 11, corresponding magnetic valve is opened, by water supply tank
Cold water in 10 fills into heavy caliber solar energy heat collection pipe 9, adjusts water temperature, makes it stable in predetermined temperature.Stop transporting in vehicle
After row, the hot water that is cooled in thermal-collecting tube 9 by variable heat-exchanger pump 6 squeeze into water supply tank 10 store it is stand-by.As long as former car warm wind is dissipated
The hot power of device 8 is appraised and decided, and calculates accurate, roof area using rationally, the length of thermal-collecting tube 9, radical apolegamy are suitable, and controller 11 is to water
Warming answers numerical value and magnetic valve, variable heat-exchanger pump 6, electric heater 7, water compensating valve, logic control proper, is meeting that vehicle traveling will
On the premise of asking, electrical heating can consume energy reduction more than 50%, it is fine through test effect.
Heavy caliber solar energy heat collection pipe 9 is used in parallel, and thermal-arrest in-pipe flow maintains circulation by variable heat-exchanger pump 6, becomes calorimetric
The controlled device 11 of water pump 6 controls.When vehicle brings into operation, water capacity is less in heavy caliber solar energy heat collection pipe 9, and water temperature is relatively low,
As sunshine irradiates, water temperature is rapidly heated in pipe, when not reaching 8 preset temperature of warm air radiator, makees in controller 11
Under, electric heater 7 is in heating with full power state, with water in heavy caliber solar energy heat collection pipe collective effect heating system.With
The rise of water temperature, under the signal function that temperature detector 5 provides, controller 11 can send instruction, be gradually reduced electric heater 7
Power or heat time, until stopping electrical heating.After electrical heating stops, if water temperature continues to rise in system, making in controller 11
Under, magnetic valve 1 is opened, the inner cold water of water supply tank 10 is filled into heavy caliber solar energy heat collection pipe 9, water temperature is adjusted, makes it stable
In predetermined temperature, after vehicle is out of service, the first magnetic valve 1, the 3rd magnetic valve 3 are closed, and the 4th magnetic valve 4 is opened, and become calorimetric
Water in system is squeezed into water supply tank 10 by water pump 6.In whole work process controller by input and output control node A1, A3, A4,
A5, A6, A7 respectively with the temperature detector 5 on the first magnetic valve 1, the 3rd magnetic valve 3, the 4th magnetic valve 4, warm air radiator 8, variable
Heat-exchanger pump 6, electric heater 7 electrically connect to induction signal and perform function node, them is worked by the control logic of setting.Finally
Reach and make full use of heavy caliber solar energy heat collection pipe to act on, reduce ancillary apparatus energy resource consumption, increase the mesh of vehicle continual mileage
