The ribbed radiator conducts the heat to the environment. The thermo-electric generation piece uses the temperature difference of the high temperature side and the low temperature side to generate the electric energy. The utility model has the advantages of simple structure, convenient installation and credible running, which can save fuel for the vehicle.
Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), and the high temperature and the temperature difference between the ambient temperature that it utilizes blast duct for vehicle to produce produce direct current energy by the thermo-electric generation sheet, belong to new forms of energy or field of renewable energy technology.
Background technology
Vehicle is the main consumption approach of petroleum-based energy, and along with the worsening shortages of petroleum-based energy in the world, automobile energy-saving becomes more and more important vehicle index.Motor exhaust has the temperature above 600 ℃, if with its direct discharging, can cause a large amount of heat-energy losses.The thermo-electric generation sheet that utilizes semi-conductive thermoelectric principle to make has direct current and produces when producing the temperature difference, the temperature difference is high more, and electric energy is big more.The vehicle exhaust pipe differential temperature electricity generating system has advantages such as simple in structure, easy for installation, reliable, and existing vehicle can be installed and used this device through a little change.China utility model patent CN200997576Y discloses the temperature difference electricity generation device that utilizes the automobile exhaust temperature, it establishes semi-conductor thermoelectric material on the outer wall of blast pipe, but its thermoelectric material is an arc, production, installation requirement height and stability are bad, the low temperature face heat dispersion of thermoelectric material is not good, so generating efficiency is not high in actual motion.
The utility model content:
At the deficiencies in the prior art and defective, the purpose of this utility model provides a kind of device that utilizes blast duct for vehicle to carry out thermo-electric generation, and not only production technology is simple, easy for installation to make it, and perfect heat-dissipating, and generating efficiency is higher.
The technical solution of the utility model is as follows:
A kind of device that utilizes blast duct for vehicle to carry out thermo-electric generation, this device comprises blast duct for vehicle 1, blast pipe shell 2, thermo-electric generation sheet 3 and fin radiator 4, it is characterized in that: described blast pipe shell 2 is wrapped in the outside of blast duct for vehicle 1, the inner surface of blast pipe shell 2 closely contacts with blast duct for vehicle, the left surface of the outer surface of blast pipe shell, right flank and bottom surface are the plane, and the high temperature face of described thermo-electric generation sheet 3 is separately positioned on described left surface, right flank and the bottom surface; Described fin radiator 4 is arranged on the low temperature face of described thermo-electric generation sheet 3; The described thermo-electric generation sheet 3 that is arranged on blast pipe shell left surface, right flank and the bottom surface is connected with series connection or series-parallel system each other.
Technical characterictic of the present utility model also is: fill with heat-barrier material the gap between described fin radiator and the blast pipe shell.
The utility model compared with prior art, have the following advantages and the high-lighting effect: because vehicle exhaust pipe shell provided by the utility model adopts planar structure, avoided using the thermo-electric generation sheet of arc, thereby the thermal conduction resistance of plane thermo-electric generation sheet contact-making surface is reduced.The employed fin radiator of the utility model is the low temperature face heat radiation of thermo-electric generation sheet, when vehicle ', and fin radiator and surrounding air generation forced-convection heat transfer, conducting heat strengthens, and these two factors all make thermo-electric generation efficient increase.The apparatus structure that the utility model provides is simple, easy for installation, reliable, can be the vehicle fuel saving.

Among the figure: 1-blast duct for vehicle, 2-blast pipe shell, 3-thermo-electric generation sheet, 4-fin radiator, 5-heat-barrier material.
Embodiment
Below in conjunction with accompanying drawing principle of the present utility model, the course of work and embodiment are further described.
Fig. 1 and Fig. 2 are respectively that the blast duct for vehicle that utilizes that the utility model provides carries out the planar structure schematic diagram and the perspective view of temperature difference electricity generation device, this device comprises blast duct for vehicle 1, blast pipe shell 2, thermo-electric generation sheet 3, fin radiator 4, heat-barrier material 5.Blast pipe shell 2 is wrapped in the outside of blast duct for vehicle 1, and contact closely makes its heat conduction good.Blast pipe shell 2 is made by the good material of heat conductivility.The left surface of the outer surface of blast pipe shell 2, right flank and bottom surface are the plane of low roughness, all place thermo-electric generation sheet 3 on these three planes, and blast pipe shell plane contacts with the high temperature face of thermo-electric generation sheet 3.The low temperature face of the bottom of fin radiator 4 and thermo-electric generation sheet 3 contacts, and the fin arranged direction of fin radiator 4 is favourable crosses each heat-transfer surface of fin with air flow stream in vehicle '.The high and low temperature face of thermo-electric generation sheet 3 is all coated heat-conducting silicone grease to strengthen heat conduction.
The quantity of thermo-electric generation sheet 3 is decided by that Tail Pipe Temperature distributes, and the blast pipe working temperature of thermo-electric generation sheet 3 locas can not surpass the specified maximum temperature of thermo-electric generation sheet 3.Each thermo-electric generation sheet 3 is linked to be circuit in modes such as serial or parallel connections.The space of thermo-electric generation sheet 3 between blast pipe shell 2 and fin radiator 4 adds heat-barrier material 5, makes heat be difficult for transmitting.
When vehicle ', blast pipe 1 discharging high-temperature gas, and fin radiator 4 dispels the heat because of the air forced convection, makes thermo-electric generation sheet 3 high temperature face and low temperature face reach the bigger temperature difference and produce direct current, and direct current is charged into Vehicular accumulator cell by the DC/DC conversion.The electric energy that produces according to thermo-electric generation sheet 3 and the rated voltage of storage battery can be with the generate electricity circuit of sheet 3 of different series and parallel mode combined temperature differences.
