Benefits of technology

The patent text describes a heat dissipation assembly for electronic devices such as computers. The assembly includes multiple fan assemblies to prevent overheating of components in the devices. Each fan assembly has a shell and a fan with baffles. The baffles are easily swayed by air blown by the fans, which causes the baffles to hit each other. The technical effect of this invention is to prevent damage to electronic devices from overheating caused by excessive heat generated by components.

Problems solved by technology

However, the baffles are easily swayed by air blown by the fans, which causes the baffles to hit each other.

Embodiment Construction

[0012]The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

[0013]FIG. 1 shows an embodiment of a fan assembly 100, which includes a shell 20, two fans 40, and two air shield apparatuses 60.

[0014]The shell 20 includes a front plate 21. The front plate 21 defines two circular receiving spaces 22 in the shell 20. The fans 40 are received in the receiving spaces 22 of the shell 20. An air outlet 212 is defined in the front plate 21 and communicates with each receiving space 22.

[0015]FIGS. 2-4 show that each air shield apparatus 60 includes a substantially rectangular bracket 62, a plurality of baffles 64, and a plurality of connecting members 66.

[0016]The bracket 62 includes a first side plate 621 and a second side plate 622 opposite to the first side p...

Abstract

An air shield apparatus includes a bracket and a number of baffles. The bracket includes a first side plate and a second side plate opposite to the first side plate. The first side plate defines a number of first shaft holes, and the second side plate defines a number of second shaft holes aligning with the first shaft holes. Each baffle includes a blocking piece between the first and second side plates, and two opposite posts protruding out from two opposite ends of the blocking piece. The posts of the baffles are pivotably received in the first shaft holes and the second shaft holes. An inner wall of each shaft hole defines a helical guiding groove. A helical sliding portion winds around each shaft. The sliding portion of each baffle is rotatably received in the corresponding guiding groove of the first and second side plates.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to fan assemblies, and particularly to a fan assembly with an air shield apparatus.[0003]2. Description of Related Art[0004]Electronic devices, such as computers, use heat dissipation assemblies for dissipating heat generated by components therein, thus preventing the components from overheating. The heat dissipation assembly includes a number of fan assemblies blowing air to dissipate heat generated from the electronic devices. Each fan assembly includes a shell, a fan received in the shell, and a number of baffles. Two opposite sides of the shell define a plurality of shaft holes. Two opposite shafts protrude out from two opposite ends of each baffle. The shafts of each baffle are rotatably received in the corresponding shaft holes. However, the baffles are easily swayed by air blown by the fans, which causes the baffles to hit each other.BRIEF DESCRIPTION OF THE DRAWINGS[0005]Many aspects of the present embodi...
