In order to understand the technical characterstic of the utility model better, below in conjunction with accompanying drawing this patent is done explanation further, need to prove that embodiment is not the restriction to this patent protection domain.
As shown in Figure 1; The utility model truck tail gas temperature difference electricity generation device; Comprise the exhaust collection passage 5 that is communicated with the truck tail gas outlet pipe, be close to exhaust collection passage 5 high temperature liquid case 6, be close to high temperature liquid case 6 temperature-difference power generation module 7, be close to the low temperature liquid case 9 of temperature-difference power generation module 7; This electricity generating device also comprises radiation system 1 and baffle-box 2; The outlet of said high temperature liquid case 6 is communicated with the inlet of radiation system 1 through hydrothermal solution pipe 11; The outlet of radiation system 1 connects the inlet of baffle-box 2 through separator tube 1-1; Baffle-box 2 outlet connect the inlet of low temperature liquid casees 9 through cool liquid tube 3, the outlet of low temperature liquid case 9 is communicated with the inlet of high temperature liquid case 6 through pipeline, said temperature-difference power generation module 7 is electrically connected with the charging system of truck.
The series connection of temperature-difference power generation module 7 through the thermo-electric generation sheet obtains electric current and the voltage that storage battery is fit to parallelly connected.
In said high temperature liquid case 6, low temperature liquid case 7, radiation system 1, the baffle-box 2 cycle fluid is housed.Said cycle fluid is a liquid, can adopt 1,2-propylene glycol etc.1, the 2-propylene glycol has no toxicity, is mainly used in the aspects such as emulsifier and toothpaste of food, even leak, also has no harm; Burning-point is 421.1 ℃, and much larger than boiling point 188.2 ℃ do not have spontaneous combustion danger; Can not cause corrosion to casing; Fusing point is-59 ℃, under the normal condition, can not freeze; Specific heat is moderate, is 2.49kJ/ (kg. ℃), between the 1.00kJ/ of 4.19kJ/ of water (kg. ℃) and air (kg. ℃), can not be difficult to heating and cooling because of Tai Gao, can be not low because of too yet, can't dispel the heat at temperature difference sheet huyashi-chuuka (cold chinese-style noodles); Low price, convenient and practical.
Said exhaust collection passage 5, high temperature liquid case 6, low temperature liquid case 9 are rectangular configuration, also can adopt other shapes as the case may be certainly.
Said temperature-difference power generation module 7 is the thermo-electric generation sheet, about about 200.Whole temperature-difference power generation module size is 5mm * 140mm * 875mm, and temperature difference sheet model is TEC1-03130T125, when the temperature difference of huyashi-chuuka (cold chinese-style noodles) and hot side reaches 80 ℃; Monolithic temperature difference sheet can obtain the power of 6V * 3A=18W, every chip size, length * wide * height=35mm * 35mm * 5mm; Generating efficiency 4.7%; Resistance is 0.09 Ω, and quality is 36g, and high temperature resistant is 200 ℃.
Low temperature liquid case 9, Dimensions: length * wide * height=875mm * 140mm * 5mm, case is thick to be 2mm, its material is 304 corrosion resistant plates of zinc-plated processing.Long 800mm～the 1000mm of said high temperature liquid case, wide 120mm～140mm, high 30mm～50mm, casing wall thickness 2mm～3mm.
Radiation system 1, the employing radiator of water tank adds the heat radiation form of fan, after the liquid after the cooling comes out from radiation system 1; Enter into baffle-box 2, a joint relief valve 2-1 is stretched out in baffle-box 2 tops, and relief valve 2-1 opening is fixed on the higher position with respect to whole device; And in baffle-box 2 back; A little water pump is arranged, and for cooling circulation liquid provides circulation power, the circulating liquid meeting is automatic cycle owing to heat.Also can on the pipeline of cool liquid tube 3, increase recycle pump, to help acceleration cycle.The Dimensions of baffle-box 2 is: length * wide * height=200mm * 200mm * 50mm; One of its effect is to prevent the violent vaporization of circulating liquid heating; Extruding is perhaps risen and is split exhaust collection passage 5, high temperature liquid case 6, low temperature liquid case 9 etc.; Two be that the circulating liquid that cooling is come out can carry out short stay at baffle-box 2, further in air, reduce the circulating liquid temperature.
Said high temperature liquid case 6 is provided with pressure-limit valve 8, and pressure-limit valve 8 is to cause liquid case blast for fear of line clogging and be provided with, and the voltage limiting value of pressure-limit valve 8 only is higher than barometric pressure a little, can increase the susceptibility of pressure-limit valve.Pipeline in device or the liquid overflow hole of relief valve 2-1 stop up, and pressure-limit valve 8 is reaction rapidly, and the High Temperature Gas liquid mixture is discharged to the external world.
The electric energy that temperature-difference power generation module 7 produces is directly connected to the battery charger of truck.Electric energy is mainly used in two purposes: the electricity consumption of former all electrical equipment of delivery truck; Change the air compressor of truck and air condition compressor into electrodynamic type by the drive-type of motor.
Said high temperature liquid case has the preheating section of being longer than low temperature liquid case, and promptly the length of high temperature liquid case is greater than the length of low temperature liquid case, the equal in length of the length of said temperature-difference power generation module and low temperature liquid case.Circulating liquid generates electricity if get into high temperature liquid case 6 immediately, because heating time is extremely short after coming out from low temperature liquid case 9; The temperature at thermo-electric generation sheet two ends is almost equal; So can produce electric current so hardly. the low temperature liquid inlet of high temperature liquid case 6 lengthening is such the first, can give the circulating liquid preheating that gets into high temperature liquid case 6; Its flow to the temperature difference send out module 7 places reach with respect to the high temperature of low temperature liquid case 9, thereby produce enough electric currents; The second, corresponding low temperature liquid case 9 does not prolong, and can reduce the quantity of thermo-electric generation sheet like this, reduce cost, and the volume that reduces electricity generating device.
Truck tail gas gets into through exhaust collection passages 5 and from exporting 10 from outlet pipe import 4 and discharges, during cryogenic liquides in the high temperature liquid case 6 that both sides are close to be heated as high-temp liquid, this high-temp liquid is that the temperature-difference power generation module of being close to 7 provides hot-side temperature; The high-temp liquid approach hydrothermal solution pipe 11 that comes out from high temperature liquid case 6 gets into radiation system 1; After coming out from radiation system 1, temperature of high-temp liquid reduces, and cushions at baffle-box 2; Get into crogenic box 9 through cool liquid tube 3, the cryogenic liquide in the crogenic box 9 is that temperature-difference power generation module 7 provides cold junction temperature.This cryogenic liquide repeats to get into high temperature liquid case 6 and heats then, so constantly circulation.
Just can realize this patent preferably as stated.
