Embodiment Construction

[0026] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, and are described in detail as follows:

[0027] Please refer to image 3 As shown, the fan frame of the axial flow cooling fan of the present invention includes a frame body 10 , a bearing seat 20 and several stator blades 30 . The two ends of the frame body 10 form an air inlet 11 and an air outlet 12 respectively; the bearing seat 20 is located at the air outlet 12 of the frame body 10; The inner peripheral wall of the frame body 10 enables each of the vanes 30 to be arranged radially around the receiving portion 20 . Also, the main technical feature of the fan frame of the present invention is that each of the stationary vanes 30 has an included angle (θ) between each other, and each of the included angles (θ) has an angl...

Abstract

The invention relates to a fan frame of an axial-flow type cooling fan. The fan frame comprises a frame body, a bearing seat and a plurality of static blades, wherein an air inlet and an air outlet are formed in the frame body; the bearing seat is located at the air outlet of the frame body; one end of each static blade is connected with the bearing seat, and the other end of each static blade is connected with an inner side circumferential wall of the frame body; besides, an included angle is formed between every two adjacent static blades, each included angle has an angle value, and a plurality of included angles formed by a plurality of static blades respectively have more than two kinds of angle values, so that the static blades can be ranked at different intervals. Therefore, when airflow passes through the static blades, noises with the same vibrational frequency are difficult to produce.

Description

technical field [0001] The present invention relates to a fan frame structure, in particular to a fan frame of an axial flow cooling fan with stator blade design. Background technique [0002] At present, the fan wheels of common heat dissipation fans on the market all have several blades, and each of the blades has an included angle with each other, and the angles of each of the included angles are exactly the same. Therefore, when the blades of the fan wheel drive the airflow to perform heat dissipation, noise (tone) of the same vibration frequency is likely to be generated, and the noise of a single frequency is further formed through the transmission of air. [0003] For example, China Taiwan Application No. 97132907 "Heat Dissipation Fan Wheel" invention patent, the blades of the fan wheel are designed to have different angles between the blades, so that the fan wheel drives the external air flow for heat dissipation. The blades are less likely to generate noise (Tone)...
