The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Referring to Fig. 1, a kind of heating device of electric automobile, be provided with the fule heater 1 that is used for the auxiliary air conditioner heating in the electronlmobil, air-conditioning comprises air-conditioning heater core 37 and air conditioner blower 38, fule heater 1 connects fuel tank, fule heater 1 inside is provided with H Exch, described H Exch interlocks water pump 33 by internal water, water pump 33 connects expansion tank 32 by pump water inlet 34, described H Exch connects H Exch coolant outlet pipe 35 1 ends by the internal water cover simultaneously, H Exch coolant outlet pipe 35 other ends connect air-conditioning water inlet 36, and air-conditioning water outlet 39 connects expansion tank 32 by air-conditioning coolant outlet pipe 31.
Adopt heating device of electric automobile of the present invention, use, be used by fule heater and electric air-conditioning in the area of severe cold, warm oneself, defrosting, demist, electric air-conditioning need not to use the PTC heating, thereby has saved the energy of battery, the tractive performance of the car load of assurance.
Referring to Fig. 2 and Fig. 3, fule heater 1 connects fuel tank 9 by fuel feed pipe 6, fuel tank 9 is provided with weight valve 10, weight valve 10 connects canister 12 by freeing pipe 11, canister 12 connects minipump 4 by fuel-steam pipe 5, minipump 4 connects fuel-steam pipe admission port 2 by vacuum pump outlet fuel-steam pipe 13, and fuel-steam pipe admission port 2 is located on the air inlet pipe end of fule heater 1, and air inlet pipe is to be used for to supplying air in the combustion chamber.
Referring to Fig. 4, be provided with the inner fuel-steam pipe 14 of temperature booster in the fule heater, the inner fuel-steam pipe of temperature booster 14 1 ends connect fuel-steam admission port 2, and the other end stretches in the combustion chamber 15 of fule heater.
Combustion chamber 15 is provided with exhausr port 17, fuel-steam is behind minipump 4 desorptions, be introduced in the process of combustion chamber 15 by the fuel-steam admission port 2 after the fule heater transformation of the way, set off an explosion for avoiding steam and Air mixing body to be lighted at the some spark of the motor generation that is not inhaled into the combustion-supporting fan 18 of combustion chamber 15 causes, event needs to increase inner fuel-steam pipe 14 in fule heater, the gasoline burning together after light-up plug/flame probe activates after 16 introducings atomize with spray bar with it.
The vacuum groundwork of minipump is as shown in Figure 5: the centering type circular movement of motor 21, make pump in-to-in barrier film 23 do reciprocating by link-type mechanical device 22, thereby to the formation vacuum (negative pressure) of compressing, stretches of the air in the pump chamber 24 of fixed volume, produce difference of pressure at pump bleeding point 27 places and external atmosphere pressure, under action of pressure, press (suction) to go into pump chamber 24 by bleeding point barrier film 28 gas, discharge from pump exhaust inlet 25 by exhausr port barrier film 26 again.Diaphragm material uses the oil resistant fluorosioloxane rubber.
Minipump of the present invention also can adopt commercially available minipump, as Chengdu is that the model that sincere electric mechanical center produces is series mini vacuum pumps such as VM8001, VM7002, need to change commercially available minipump barrier film into the fluorosioloxane rubber material, make its interface make the structure that to dock with car load fuel-steam pipeline fast joint into.
As a kind of preferred, be provided with controller in the fule heater, can control the opening and closing of minipump by the hole controller.
A kind of heating device of electric automobile fuel-steam recoverying and utilizing method may further comprise the steps:
(1) weight valve and the freeing pipe of the fuel-steam that produces of the fuel tank that fule heater is used in the electronlmobil on fuel tank enters canister and is adsorbed storage;
(2) fuel-steam of Chu Cuning is introduced into the minipump pump chamber from canister by the fuel-steam pipe again when minipump work desorption;
(3) fuel-steam is behind the minipump desorption, and it is burned to enter combustion chamber from the fuel-steam admission port of fule heater.
Wherein, when fule heater is worked, open by the controller control minipump of fule heater;
When minipump open canister fuel-steam desorption finished after, the controller control minipump of fule heater is closed, controller also is used for this body running of control heater.
The present invention is to be weight valve, the canister reservation of fuel tank with the traditional vehicle fuel feeding, selected canister is carried out canister active carbon resistance test, thereby measure the degree of vacuum of canister under the desorption condition of loading and the relation curve of desorption flow, according to the measurement parameter of these experiments, a kind of oil resistant steam newly developed, produce negative pressure and flow simultaneously and all satisfy miniature minipump the requirement of canister desorption; When the subprogram of revising the fule heater controller realizes fule heater work to the start and stop control of minipump, thereby replaced the unlatching closure function of conventional gasoline car electromagnetic valve; On the fule heater admission line, increase the fuel-steam interface again, motionless body also need not the die sinking tool, draw one section pipeline to the fuel atomizing chamber from this interface, like this fuel-steam is introduced canister by pipeline from the fuel tank weight valve, again from canister introducing minipump and to fule heater, control minipump time opening during fule heater work, the fuel-steam after realization fuel-steam and the fule heater atomizing is introduced into combustion chamber and burns together.
When existing fule heater product is installed on the conventional gasoline car on the market, only getting oil from former car fuel tank during work gets final product, do not influence the process of the fuel-steam desorption recycling of conventional gasoline car fuel tank breathing, fuel-steam is after being adsorbed onto canister and storing from the fuel tank weight valve, is open at by the ECU control electromagnetic valve that desorption is recycled under the inner suction function that produces of engine air inlet tube again.But when existing fule heater is used on the electronlmobil, when using Fuel Petroleum, because of no driving engine can provide negative pressure; Under the negative pressure mode of operation at fule heater body admission port place less than 100Pa, also far can't reach canister fuel-steam desorption 80000Pa left and right sides negative pressure requirement, adopt apparatus and method of the present invention, well solved fuel tank self breathing and caused fuel oil evaporation discharging and recycling problem.
Above-described embodiment, the present invention specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
