Description
Technical field
The utility model relates to a kind of electricity generating device, and the high temperature and the temperature difference between the external temperature of utilizing automotive residual heat to produce produce direct current energy by the thermo-electric generation sheet, belong to field of renewable energy technology.
Background technique
Automobile is the main consumption approach of petroleum-based energy, along with the worsening shortages vehicle energy saving of petroleum-based energy in the world seems more and more important.The temperature of motor exhaust surpasses 600 ℃, if with its direct discharging, can cause a large amount of heat-energy losses, cooling water can reach 100 ℃ through temperature behind the motor, if it is discharged into the atmosphere by wind-cooling heat dissipating, can cause the loss of heat energy.The thermo-electric generation sheet that utilizes semi-conductive thermoelectric principle to make can produce direct current when producing the temperature difference, the temperature difference is big more, and the electric energy of generation is big more.Simple in structure, easy for installation, stable, efficient advantages of higher that the device of automotive residual heat thermo-electric generation has, existing vehicle can be installed and used this device through a little change.China utility model patent CN20081024042.0 discloses and has utilized blast duct for vehicle to carry out the device of thermo-electric generation, it adopts air-cooled, because the very high speed wobble of exhaust gas temperature, thermal diffusivity is difficult to reach requirement, do not add yet and indicate concrete mounting point, so generating efficiency and stability are not high in actual motion.
Summary of the invention:
For overcoming the deficiencies in the prior art and defective, the purpose of this utility model provides that a kind of thermal diffusivity is good, good stability, automotive residual heat electricity generating device that generating efficiency is high.The technical solution of the utility model is as follows:
A kind of automotive residual heat electricity generating device, comprise automobile exhaust pipe (1), thermo-electric generation sheet (2), water-cooling tube (3), copper guide plate (4), aluminium post (5), low melting alloy (6), aluminum component (7), Sealing (8), pressure governor (9), voltage stabilizer (10), controller (11), described thermo-electric generation sheet (2) is wrapped in the outside of outlet pipe (1), water-cooling tube (3) is wrapped in the outside of thermo-electric generation sheet (2), the high temperature face of thermo-electric generation sheet (2) contacts with outlet pipe (1), and the low temperature face of thermo-electric generation sheet (2) contacts with water-cooling tube (3).
