Problems solved by technology
[0003] However, due to the long axial length of the cross-flow fan blade, the airflow flowing to the cross-flow fan blade is very easy to axially channel along the internal hollow structure of the cross-flow fan blade.
Especially in the state where the fan inlet is partially blocked or the air intake is poor, due to the difference in pressure at the axial position, the air flow will be very serious
The axial movement of the above-mentioned airflow can easily cause the vibration of the cross-flow fan blade, and the energy efficiency is relatively low

The invention discloses a fan and a cross-flow fan blade. The cross-flow fan blade comprises a fan blade body (1) and further comprises flow channeling prevention partitions (2) arranged in the inner hollow structure of the fan blade body (1) and used for axially dividing the inner hollow structure. According to the cross-flow fan blade, the flow channeling prevention partitions are arranged in the inner hollow structure of the fan blade body to play the role of axially dividing the inner hollow structure. Even under the circumference that the pressure at the axial position in the cross-flow fan blade is uneven, and airflow moves axially and flows along the inner hollow structure, after the airflow meets the flow channeling prevention partitions, airflow channeling can be interrupted, the airflow is forced to be thrown out from the corresponding position of the fan blade body, and further, axial airflow channeling is prevented. Therefore, the air input and the air output at the same axial position of the fan blade body are basically the same, vibration of the cross-flow fan blade is effectively reduced, and the energy efficiency ratio is improved.
Description
technical field [0001] The invention relates to the technical field of air supply, in particular to a fan and cross-flow fan blades thereof. Background technique [0002] Due to its low noise and large air output, cross-flow fan blades are widely used in external hanging machines and some cabinet machines. The blades of the cross-flow fan blade are arranged along the axial direction of the cross-flow fan blade, so that the cross-flow fan blade has an inner hollow structure. [0003] However, due to the relatively long axial length of the cross-flow fan blade, the airflow flowing towards the cross-flow fan blade can easily flow axially along the inner hollow structure of the cross-flow fan blade. Especially in the state where the fan inlet is partially blocked or the air intake is poor, due to the difference in pressure at the axial position, the air flow will be very serious. The axial movement of the above-mentioned air flow can easily cause the vibration of the cross-flo...
