A multifunctional fan

Abstract

The invention discloses a multifunctional fan. The multifunctional fan comprises a driving motor, blades and a water cooling device, wherein an output shaft of the driving motor is connected with the blades; the water cooling device comprises an evaporator; the evaporator comprises multiple fins; gaps are formed between adjacent fins; the multiple fins are annularly distributed at the outer peripheries of the blades; the evaporator is connected with a water tank for holding cooling liquid; a transfusion port is formed in the water tank; and the water tank is connected with a refrigerating device and a water tank for conveying the cooling liquid to the evaporator. The multifunctional fan, provided by the invention, can cool air in use, so that the temperature of the air finally exhausted by the blades is lower, the excellent heat transfer and evaporation heat absorption effect can be achieved, and the cooling effect is obvious; and in particular, the multifunctional fan is suitable for cooling in high-temperature bad environments.

Description

technical field [0001] The invention relates to the technical field of fan equipment, in particular to a multifunctional fan. Background technique [0002] The electric fan belongs to a kind of electrical appliance used for cooling. Its cooling principle is realized by heat conduction and liquid evaporation. The structure mainly includes a motor and fan blades. The motor drives the fan to rotate to increase the air flow rate. At the same time, part of the heat of the human body is taken away through heat conduction; or the sweat on the surface of the human body accelerates evaporation to achieve cooling and bring people a cool feeling in summer. [0003] However, the cooling of the electric fan must be carried out based on the relatively low air temperature. If the weather is hot and the air temperature is high, the wind blown by the fan blades is hot air. The heat exchange between the hot air and the human body and the effect of accelerating sweat evaporation are both Not ...

Problems solved by technology

[0003] However, the cooling of the electric fan must be carried out based on the relatively low air temperature. If the weather is hot and the air temperature is high, the wind blown by the fan blades is hot air. The heat exchange between the hot air and the human body and the effect of accelerating sweat evaporation are both Not obvious, that is, the cooling effect is not obvious, therefore, the purpose of cooling and heat dissipation cannot be achieved

Therefore, the electric fans commonly used at present are used when the air temperature is high, and the cooling effect is not good.

[0004] At the same time, the current commonly used electric fans can only sweep the wind in a certain area, and the sweeping range is limited to a certain extent.

Moreover, the function of the electric fan is single, and the noise is relatively large when the fan blades rotate, which cannot meet people's needs.
