Problems solved by technology

[0012] However, if figure 2 As shown, the shape of the fan shroud assembly 20 for a vehicle is generally not a symmetrical shape, and because of the limitation of space for installation to the vehicle, the space between the tapered mouth 21 forming the anti-eddy current serrations and the position of the outer edge of the shroud become

Embodiment Construction

[0044] best practice

[0045] Hereinafter, the fan shroud assembly according to the present invention as described above will be described in detail with reference to the accompanying drawings.

[0046] like image 3 As shown, the fan shroud assembly 1 according to the present invention is generally composed of a fan 150 and a shroud 160 .

[0047] First, the fan 150 is a rotary fan that transmits blown air to the heat exchanger of the vehicle while being rotated by the motor 110, and includes: a hub 120, blades 130 and a fan ring 140, and the shroud 160 includes: a cone Shaped mouth 200 , motor assembly part 300 and fixing piece 400 .

[0048] First, in order to move air by means of the fan 150, the tapered opening 200 forms an air blowing portion 100, which is a space in which a predetermined central area of ​​a plenum portion is hollow.

[0049] The electrode assembly part 300 is a part for assembling the motor for driving the fan 150 , and is located in the central area...

Abstract

The present invention relates to a fan shroud assembly and, more specifically, to a fan shroud assembly comprising: vortex-preventing saw-teeth which are arranged along a predetermined inner circumferential surface of a ventilating unit so as to maintain a predetermined gap with a blade end part or a band end part of a fan, and which are formed in a saw-toothed shape, wherein both a first area in which the vortex-preventing saw-teeth are formed and a second area from which the vortex-preventing saw-teeth are removed are formed, thereby generating vortexes of ventilated air due to a reduction in pressure fluctuation and thus effectively reducing noise.

Description

technical field [0001] The present invention relates to a fan shroud assembly, in particular to a fan shroud assembly comprising anti-eddy current sawtooth and formed with a first area and a second area, wherein the anti-eddy current sawtooth is along the inner peripheral surface of the air supply part The predetermined area is arranged at a predetermined distance from the end of the fan blade or the end of the fan ring and is formed in a zigzag shape, the first area is an area formed with anti-eddy current serrations, and the second area is an area with anti-eddy current serrations removed Therefore, the transferred air generates a vortex as the amount of pressure fluctuation becomes smaller, thereby effectively reducing noise. Background technique [0002] In the engine that generates the actual driving force of the vehicle, a large amount of heat energy is generated in the process of converting chemical energy into kinetic energy. If such heat energy is excessively gener...
