Description
Technical field
The utility model belongs to field of automobile, specially refers to the generating equipment of automobile.
Background technology
The high-temp waste gas that the automobile engine burning produces contains higher energy, but automobile exhaust gas all is directly to be discharged in the atmosphere through blast pipe at present, has caused the waste of energy.Simultaneously, automobile must utilize engine to generate electricity again, to satisfy the needs of cruising and vehicle mounted electrical apparatus, has so just increased the consumption of fuel oil, also environment has been caused more pollution naturally.The energy that how to make full use of in the waste gas of automobile generates electricity, and reduces fuel consume and environmental pollution, is the problem that a motor-dom is all being explored.
Seebeck (Seeback) effect is called first thermoelectric effect again, and it is meant the pyroelectric phenomena that cause two kinds of voltage differences between material owing to two kinds of different electric conductors or semi-conductive temperature contrast.In the loop of two kinds of metal A and B composition, if make the temperature difference of two contact points, then in the loop electric current will appear, be called thermocurrent.
The utility model content
The purpose of this utility model is to propose a kind of automobile-used semiconductor thermo-electric generation apparatus that utilizes the Seebeck effect generating, to make full use of the energy of automobile exhaust gas, reduces fuel consume and environmental pollution.
The bottom surface of automobile-used semiconductor thermo-electric generation apparatus of the present utility model is a heat-conducting plate, described heat-conducting plate is close to the outer wall of the aiutage that is fixed on automobile, be furnished with a plurality of P type semiconductor thermoelectric elements and N type semiconductor thermoelectric element on the heat-conducting plate, described P type semiconductor thermoelectric element and N type semiconductor thermoelectric element interleaved series form series circuit, and the two ends of series circuit link to each other with two outputs of this Blast Furnace Top Gas Recovery Turbine Unit (TRT).
Utilize P type semiconductor thermoelectric element and N type semiconductor thermoelectric element as the generating main body, the electric current that other conductors of its current ratio that produces under the identical temperature difference produce wants big, the energy utilization ratio height; When engine operation, the exhaust tube wall of automobile is in the condition of high temperature always, Blast Furnace Top Gas Recovery Turbine Unit (TRT) is fixed on exhaust tube wall by the heat-conducting plate of its bottom surface, make the temperature of bottom surface of P type semiconductor thermoelectric element and N type semiconductor thermoelectric element be higher than the temperature of its end face far away, according to Seebeck effect, can produce thermocurrent in the above-mentioned thermoelectric element, a plurality of P type semiconductor thermoelectric elements and N type semiconductor thermoelectric element interleaved series, make the electric current in the circuit strengthen greatly, can be applied to the miniature electrical equipment on the automobile, thereby reach the purpose that the energy that utilizes the automobile high-temp waste gas reduces fuel consume and environmental pollution.
For improving the heat utilization efficiency of Blast Furnace Top Gas Recovery Turbine Unit (TRT), described P type semiconductor thermoelectric element and N type semiconductor thermoelectric element are strip, are vertically mounted on the heat-conducting plate, and its bottom surface and heat-conducting plate are close to.Thermoelectric element is a strip, and its bottom surface and heat-conducting plate are close to, and can strengthen the temperature difference at thermoelectric element two ends, strengthens the electric current that is produced.
For further strengthening the temperature difference at thermoelectric element two ends, the end face of described P type semiconductor thermoelectric element and N type semiconductor thermoelectric element is provided with fin; Be provided with the heat radiation gap between described P type semiconductor thermoelectric element and the N type semiconductor thermoelectric element.
