Title:
AXIAL-FLOW TYPE ELECTRONIC RADIATOR FAN
Document Type and Number:
WIPO Patent Application WO/2010/081294
Kind Code:
A1
Abstract:
An axial-flow type electronic radiator fan includes a fan blade (5) and a motor. The fan blade (5) is formed in multi-stage blade structure or single-stage blade structure. The single-stage blade structure is that all of the fan blades are formed into an integral component, or that the blades are axially cut into two sections, or that the blades are respectively arranged on several integral components. Due to the structure of the fan blade, the cascade solidity and the rated bending angle of the fan blade could be improved, the eddy current loss caused by the air flow separation on the back of the blade could be decreased, and the performance of the fan could be improved.
