High-efficiency cooling fan and air-funnel blade thereof

Abstract

A fan blade having an air-funnel structure. By providing a plurality of embedded air funnels on the blade, and on the basis of the effect of the increase in flow velocity due to the change in the cross-section of an airflow channel, the cooling capability of the fan is significantly enhanced. The fan blade can not only provide a more comfortable use experience, but also achieve good energy saving and noise reduction effects, and meets the air circulation and temperature regulation requirements under various environmental conditions.

Description

[0001] High-efficiency cooling fan and its wind funnel blade

[0002] Patent specification

[0003] TECHNICAL FIELD

[0004] The present invention relates to an improved fan design, particularly a blade with an embedded wind funnel structure, which aims to enhance airflow speed to improve cooling efficiency, suitable for various occasions requiring air circulation and cooling.

[0005] BACKGROUND

[0006] Traditional fans mainly rely on electric motors to drive the rotation of the blades to generate airflow, achieving the effect of ventilation and heat dissipation. However, with the improvement of people's quality of life, the traditional fan design has not been able to meet the demand for high-efficiency cooling. In order to improve this situation, some attempts have appeared on the market, such as increasing fan power or changing blade shape, but these methods often come with problems such as increased noise and increased energy consumption.

[0007] SUMMARY

[0008] The present invention proposes a new fan blade design - "wind funnel" blade, which embeds a specially designed wind funnel structure on the basis of traditional blades, uses physical principles (i.e. high-speed airflow carries away more heat), adjusts the cross-sectional area ratio of the airflow channel, so that the normal temperature air can accelerate when passing through the blade, thereby effectively improving the local wind speed and achieving better cooling effect.

[0009] TECHNICAL SCHEME

[0010] 1. The blade / wind funnel is made of high-strength lightweight material to ensure that it does not deform when rotating at high speed. 2. According to the size of the blade, there are several wind funnel structures distributed on the blade, with the large end facing the inlet direction and the small end facing the outlet direction.

[0011] 3. The wind funnel is designed with a smooth transition curve inside to reduce airflow resistance and ensure smooth airflow. 4. By optimizing the geometric parameters of the wind funnel (such as length-diameter ratio, opening angle, etc.), the airflow acceleration efficiency is further improved.

[0012] 5. The blade is installed with a wind deflector to adjust the direction and range of airflow.

[0013] 6. The motor of the fan uses a temperature sensor and control system to automatically adjust the working state of the fan, further improving energy saving and noise reduction effect.

[0014] ADVANTAGEOUS EFFECTS

[0015] -Enhanced cooling effect: Compared with ordinary fans, the invention can increase the local wind speed by at least 100%, thereby achieving better cooling effect.

[0016] -Energy saving and noise reduction: Due to the use of efficient airflow guiding mechanism, the required power consumption is lower under the same cooling effect, and the noise generated by high load operation of the motor is also reduced.

[0017] -Wide range of applications: Whether it is for household or commercial use, it can be flexibly applied to, for example, car water tank, high-energy battery pack, etc., and is particularly suitable for rapid cooling demand in high-temperature environment in summer.

[0018] DETAILED DESCRIPTION

[0019] In the actual manufacturing process, first of all, according to the design drawing, select the appropriate materials and processing technology, complete the preliminary modeling of the fan blade and the air funnel;

[0020] Then the air funnel and the fan blade are prepared by injection / blow molding / metal welding, etc., and the overall balance correction is carried out to ensure smooth operation; finally, it is assembled on the fan body, and after performance test, it can be put into use.
