Background technique

The machine that motor is is mechanical energy by the transformation of energy of a certain form.Its function is that the chemical energy of liquid or gas is converted into heat energy after burning, then heat energy is converted into mechanical energy external outputting power by expansion, and the power of automobile is from motor.Motor is the heart of automobile, for the walking of automobile provides power, is being related to power character, Economy, the feature of environmental protection of automobile.In simple terms, motor is exactly an energy transfer mechanism, by the heat energy of gasoline (diesel oil) or rock gas, by the gas expansion that burns, promotes piston acting in sealing air cylinder, changes mechanical energy into, and this is the most basic principle of motor.All structures of motor are all transformation of energy service, and motor is accompanied by the history that automobile has been passed by more than 100 year, be in design, manufacture, technique or all improving a lot aspect performance, control, but its basic principle does not still change.Radiator claims again radiator, is critical part in automobile cooling system, and its function is distribute heat, cooling water absorbs heat in water jacket, after flowing to radiator, heat is left, return in water jacket and circulation constantly, thereby the motor of automobile can be run well.

But, the tail gas of motor is directly emitted in the external world at present, the air that not only can arrive in our life plays contamination, and heat in tail gas is also discharged in air thereupon, cause a large amount of wastes of thermal energy, reduce to some extent to the distance travelled that makes automobile, energy-conserving and environment-protective performance is not good, there is defect in practicability, exists certain deficiency.

In sum, for the defect of prior art, need especially a kind of electricity generating device that reclaims engine tail gas heat quantity, to solve the deficiencies in the prior art.

Model utility content

Directly be discharged into the deficiency existing in the external world for motor exhaust in prior art, cause a large amount of wastes to heat energy, the utility model proposes a kind of electricity generating device that reclaims engine tail gas heat quantity, novel in design, by the heat recovery of motor exhaust being arrived to radiator the inside, the electric energy transforming by the thermo-electric generation sheet of radiator internal series-connection passes to battery pack after supercharging, to address the deficiencies of the prior art.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of electricity generating device that reclaims engine tail gas heat quantity, comprise motor, radiator, the tail gas output tube of motor is connected with end gas residual heat withdrawer, end gas residual heat withdrawer inside is distributed with heat screen pipe, one port of heat screen pipe connects radiator by heat transport tube, the another port of heat screen pipe is communicated with the outlet pipe of emission, the inside of radiator is distributed with the thermo-electric generation sheet group being in series, and the electricity that thermo-electric generation sheet group produces connects battery pack by electric energy output end mouth through excess current pressurized machine.

A side at the housing of radiator described in the utility model is provided with water inlet, and the opposite side of the housing of radiator is provided with return pipe, and water inlet connects heat transport tube.

Further, thermo-electric generation sheet is uniformly distributed in radiator inside.

The beneficial effects of the utility model are: this product structure is simple, can reclaim the heat in motor exhaust, be delivered to radiator the inside by the heat reclaiming, the heat producing by motor and the heat of recovery heat and the air-cooled obvious temperature difference of water generates water, thermo-electric generation sheet just can generate electricity, increase the distance travelled of automobile with this, and reduce the discharge of tail gas, energy-conserving and environment-protective performance is excellent, novel in design, be a kind of well innovation scheme, have very much marketing prospect.
