Description

Improvement of vortex fan structure

The novel creation relates to an improved vortex fan structure which is a vortex fan structure for diversion.

Generally, the vortex fan widely used in the market rotates by the internal impeller, and illuminates the airflow for heat dissipation, and most of them concentrate and improve only the airflow generated by the impeller, but ignore a large amount of vortex airflow around the vortex channel. At this time, it is easy to generate a high pressure value for the impeller, and finally, noise is increased and the air flow is destroyed to reduce the efficiency of the impeller, thereby affecting the practicability of the structure.

In view of the above-mentioned shortcomings, the creators of this novel believe that they have the urgent need to make corrections. They have been engaged in the design and manufacture of related products for many years, and they have always adhered to the excellent design concept, and researched and created the above disadvantages. After continuous efforts, the new eddy current fan structure was improved, which improved the product's efficiency by correcting the excellent product structure.

The main purpose of the novel creation is to improve the drawbacks of the conventional vortex fan. The disadvantage is that when a large amount of vortex airflow surrounds the vortex channel, it is easy to generate a high pressure value to the impeller, which ultimately causes noise and damages the airflow. The phenomenon of reducing the efficiency of the impeller has a considerable improvement in the practicality.

In order to achieve the purpose of the previous disclosure, the novel creation is an improved vortex fan structure. The utility model comprises a trolley and an auxiliary plate. The fan frame is mainly composed of a substrate, a through pipe, an air flow passage and a combined plate. The base of the substrate has a substrate opening, and a through pipe extends upward around the opening of the substrate. A vortex channel is formed in the through pipe for the device to be an impeller, and the vortex channel is outwardly opened with a plurality of vortex-like air flow passages, and the air flow passage is an arc-shaped passage and the flow direction of the gas generated by the impeller Consistently, the structure can discharge part of the vortex airflow to the outside by the airflow passage around the vortex channel, so as to avoid a large amount of vortex airflow generating a higher pressure value to the impeller in the vortex channel, thereby improving the impeller operation. The noise generated, and effectively improve the efficiency of the impeller, increase the value and practicability of the product, and thus enhance its practical value.

The novel creation system relates to a structure improvement of a vortex fan, [refer to the first figure], which comprises: a fan frame (1), mainly composed of a substrate (11), a through pipe (12), an air flow passage (13) and a composite plate ( 14) composed of a substrate (11) [Please refer to the second figure] The substrate (11) has a substrate opening (111) at the center thereof, and a through tube (12) extends upward around the substrate opening (111), [please refer to the third figure together] A vortex channel (121) is formed in the through pipe (12) for the device to be an impeller (2), and the vortex channel (121) is outwardly opened with a plurality of vortex-like airflow channels (13), and the airflow channel (13) ) is an arc-shaped passage that coincides with the flow direction of the gas generated by the impeller (2), and is provided with a composite plate (14) disposed at the other end of the through pipe (12) and on the composite plate (14) A composite plate opening (141) is provided, the composite plate opening (141) corresponding to the vortex channel (121), allowing gas to pass through the substrate opening (111), the vortex channel (121) and the composite plate opening (141); the impeller (2) Mainly composed of a hub (21) and a blade (22), a hub (21) is disposed in the vortex channel (121), and a motor (211) is disposed in the hub (21) to Providing a power source for the operation of the impeller (2), and a plurality of blades (22) are disposed around the outer circumference of the hub (21). When the hub (21) is driven by the motor, the blades are combined. Moving, to generate airflow.

The improved vortex fan structure of the present invention is implemented, and [see the fourth figure] when the motor (211) is driven by electric power, the hub (21) and the blade (22) can be driven to rotate to one side, and the blade ( 22) When rotating in the vortex channel (121), the airflow generated by the blade (22) can form a vortex around the vortex channel (121), when the vortex formed by the airflow is wound around the airflow channel (13) Part of the vortex flow can be discharged to the outside with the arc-shaped air flow passage (13) to avoid a large amount of vortex flow in the vortex passage (121) to cause a higher pressure value on the impeller (2), and Produce noise and Destruction of the direction of the airflow.
