Example Embodiment

[0035] Example 1

[0036] Such as Figure 1-3 As shown, a multifunctional fan includes a drive motor 1, a fan blade 2 and a water cooling device, and the output shaft of the drive motor 1 is connected to the fan blade 2;

[0037] The water cooling device includes an evaporator 3. The evaporator 3 includes a plurality of fins. There are gaps between adjacent fins. The plurality of fins are annularly distributed on the periphery of the fan blade 2. The evaporator 3 is connected to contain the cooling liquid. The water tank 4 is provided with a liquid infusion port 5 on the water tank 4, and the water tank 4 is connected with a refrigeration device and a water pump 6 for delivering cooling liquid to the evaporator 3.

[0038] The air is supplied by driving the motor 1 and the fan blades 2. However, the combination of a water cooling device can further send out cold air, that is, wind with a lower air temperature. Specifically, when in use, the cooling device cools the coolant in the wa...

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 ...
