Abstract

The invention discloses a double-laminated-blade axial flow fan which comprises a fan assembly, wherein the fan assembly comprises a middle connecting piece and double-laminated blades, each double-laminated blade comprises a first connecting blade, a second connecting blade and an arc-shaped connecting piece, each arc-shaped connecting piece comprises a first connecting section, a middle connecting section and a second connecting section, and each arc-shaped connecting piece is in an N or S shape; the first connecting blade is provided with a first arc-shaped tail end, and the second connecting blade is provided with a second arc-shaped tail end. The design of the double-laminated blades is adopted, the balance stability and strong wind pressure of the fan blades during operation are achieved, the unbalance amount of the fan blades is greatly reduced, the N-shaped or S-shaped arc-shaped connecting blades are connected with the tail portions of the first connecting blades and the tail portions of the second connecting blades, wind shear resistance is reduced, and therefore, vibration generated by the fan is reduced, and overall noise generated during operation of the fan is lowered. Noise can be reduced while wind power and wind pressure are improved, and the problem that noise cannot be reduced while wind power and wind pressure are improved is solved.

Description

technical field [0001] The invention relates to the field of radiators, in particular to an axial flow fan with double laminated blades. Background technique [0002] At present, in the electronics industry, the heat emitted by electronic components is immeasurable, especially the electronic chip, which controls the operation status of the entire electronic system; the heat energy will cause serious damage to the components themselves, and will also accelerate the aging of peripheral devices. reduce its service life. The radiator can reduce the temperature of the components, and the fan, as an active cooling component commonly used in the cooling system, is indispensable in the radiator; it plays a vital role in the entire cooling process; so the performance of the fan is directly related to The thermal performance of the radiator. [0003] However, the existing radiators have the following disadvantages: [0004] 1. For the heat dissipation fan in the traditional radiato...
