Wind energy feedback type fan

Abstract

Wind energy of various existing fans is directly wasted and is not provided with a recovery device. According to the scheme, a wind energy direct reutilization mode is adopted, and the purpose of saving energy is achieved. The scheme comprises a power fan, a motor or a power main shaft, a planetary gear and other transmission devices, an energy absorption fan and the like. According to the scheme, a fan system such as an air conditioner adopts a through shaft motor or a power main shaft, wind energy of a fan of the air conditioner and the like is recycled through another energy absorption fan, the speed is increased through a gear and the like, and then the wind energy is fed back to the motor or the power main shaft, so that the purpose of energy conservation is achieved. A certain requirement is made for the transmission ratio of the gear, and effective feedback needs to be guaranteed. Part of electric energy of the fan can be saved.

Description

Technical Field

[0001] Manufacturing of electric fans, refrigerators, and air conditioners. Background Technology

[0002] Existing electric fans, refrigerator fans, and air conditioner fans all directly blow air or dissipate heat to the outside environment without any energy-saving measures. This solution, however, utilizes the airflow energy of the fans directly to achieve energy conservation. Summary of the Invention

[0003] This solution mainly consists of a power fan, a motor or power spindle, planetary gears or other transmission devices, and an energy-absorbing fan. Detailed Implementation

[0004] This solution employs a through-shaft motor or power spindle, with a power fan mounted at one end and a planetary gear or other transmission device at the other end. Another set of energy-absorbing fans is mounted on this planetary gear or other transmission device. When the power fan rotates, the generated wind energy is absorbed by the energy-absorbing fans and fed back to the power shaft via the planetary gear or other transmission device. By setting the angle of the energy-absorbing fans to determine the rotation direction, the obtained wind energy can be positively fed back to the motor or power spindle; and by accelerating through the planetary gears or other transmission device, the obtained energy can be effectively fed back to the power shaft.

[0005] Potential problems:

[0006] The transmission ratio of planetary gears and other transmission devices has certain requirements. That is, the rotational speed after the speed increase through the planetary gears and other transmission devices must exceed the rotational speed of the power shaft in order to effectively transfer the acquired wind energy.

[0007] If necessary, an overspeed clutch should be used.

[0008] Beneficial effects:

[0009] Based on the principles of this scheme, the wind energy from fans such as air conditioners can be directly recovered and reused without the need for power generation. Theoretically, this can save a portion of electrical energy without intermediate energy consumption and eliminate the need for generators, batteries, or other such devices.

Claims

1. A method for recycling the wind energy of a refrigerator or air conditioner fan. The principle is to use a planetary gear or other transmission to recycle the wind energy of the refrigerator or air conditioner fan through another energy-absorbing fan and directly feed back to the driving shaft, thereby achieving the purpose of energy saving.
