In figure: 1, insulating substrate, 2, seal ring, 3, conductive filler material layer, 4, heat exchange duct, 5, N-type thermoelectric film layer stretches out pin, and 6, P type thermoelectric film layer stretches out pin, 7, housing, 8, through hole, 9, N-type thermoelectric film layer, 10, P type thermoelectric film layer, 11, heat exchanger, 12, positive electrode, 13, thermal-protective coating and 14, negative electrode.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technological scheme: a kind of tail gas electricity generating device of automobile, comprise N-type thermoelectric film layer 9, P type thermoelectric film layer 10 and heat exchanger 11, N-type thermoelectric film layer 9 is arranged on the below of housing 7, housing 7 is provided with the through hole 8 evenly arranged, the lower-left end of N-type thermoelectric film layer 9 is provided with N-type thermoelectric film layer and stretches out pin 5, the right-hand member of N-type thermoelectric film layer 9 is provided with negative electrode 14, the below of N-type thermoelectric film layer 9 is provided with insulating substrate 1, the below of insulating substrate 1 is provided with seal ring 2, thermal-protective coating 13 is installed between seal ring 2, P type thermoelectric film layer 10 is arranged on the top of heat exchange duct 4, the left upper end of P type thermoelectric film layer 10 is provided with P type thermoelectric film layer and stretches out pin 6, N-type thermoelectric film layer stretches out pin 5 and stretches out pin 6 with P type thermoelectric film layer and dock, the right-hand member of P type thermoelectric film layer 10 is provided with positive electrode 12, heat exchanger 11 is made up of conductive filler material layer 3 and heat exchange duct 4, heat exchange duct 4 is arranged on the inside of conductive filler material layer 3.
Working principle: during use, this tail gas electricity generating device of automobile is installed, heat exchange duct 4 docks with the exhaust port of automobile, vehicle exhaust enters heat exchanger 11, carry out the transmission of heat, heat finally passes to P type thermoelectric film layer 10, the temperature of P type thermoelectric film layer 10 is higher than N-type thermoelectric film layer 9, from Thomson effect, when in metal, temperature is uneven, the free electron of temperature eminence is larger than the free electron kinetic energy of temperature lower, thermodiffusion can be produced, therefore free electron spreads from temperature is high-end to temperature low side, pile up in low-temperature end, thus electric field is formed in conductor, draw into a potential difference, generation current.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
