Background

At the present stage, air conditioners are widely used in thousands of households and industries. When the air conditioner is used for air temperature adjustment, a compressor or a motor is operated to generate a large amount of heat to be directly discharged into air, and energy waste is caused.

Disclosure of Invention

In order to recycle the heat that the air conditioner operation produced, the utility model provides an utilize air conditioner thermoelectric generation's module.

The utility model provides a pair of utilize module of air conditioner thermoelectric generation, including thermoelectric generation piece, contravariant module, prevent module and battery against the current, the thermoelectric generation piece respectively with contravariant module, battery electric connection, the contravariant module with prevent module electric connection against the current.

And part of direct current generated by the thermoelectric generation piece is stored in a storage battery, part of direct current is converted into 220V or 380V alternating current through the inverter module, and the alternating current is transmitted to the anti-reflux module through filtering and the like and finally output to electric equipment for use. The anti-backflow module (also called as anti-reverse module) mainly prevents other power supplies from flowing back to the power generation module.

Further, still include the conducting strip, the conducting strip with thermoelectric generation piece is connected. The heat conducting sheet is close to the high-temperature side generating the heat source, and heat is transferred to the thermoelectric generation sheet through heat transfer.

Further, the thermoelectric generation piece is made of N-type and P-type thermoelectric conversion materials, one end of the N-type and P-type thermoelectric conversion materials is combined, and the other end of the N-type and P-type thermoelectric conversion materials is open-circuited. One end of the N-type thermoelectric conversion material and the P-type thermoelectric conversion material which are combined is arranged on the high-temperature side of a motor, a compressor, a heater or a fin and the like, the other end of the open circuit is arranged on the low-temperature side of an air outlet of an air conditioner and the like, and due to the fact that the thermal excitation effect of the high-temperature side is strong, the concentration of holes and electrons is higher than that of the low-temperature side, the holes and the electrons are diffused to the low-temperature end under the driving of the carrier concentration gradient, and.
