1. Technical Field
The present disclosure relates to chassis assemblies, and more particularly to an enclosure with a airflow guiding duct.
2. Description of Related Art
A fan is generally mounted in an chassis of an electronic device, such as a computer, for dissipating heat generated from electronic components in the electronic device. An airflow guiding duct is usually mounted in the chassis, for guiding the airflow, increasing efficiency of the fan of bringing the heat out of the chassis. The airflow guiding duct of related art is mounted in the chassis with fasteners, such as screws or bolts. This method for mounting the airflow guiding duct involves many fasteners and adds cost of labor. Thus, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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.”
Referring to
The chassis 10 includes a bottom plate 11, a rear plate 13, and a front plate 15. The rear plate 13 and the front plate 15 extend from two opposite sides of the bottom plate 11. The rear plate 13 and the front plate 15 are substantially perpendicular to the bottom plate 11. The bottom plate 11 defines two rectangular holes 113. Two pivot pieces 111 are located on the bottom plate 11. Each of the two pivot pieces 111 extends from an edge of each of the two rectangular holes 113. The two pivot pieces 111 are substantially parallel to each other and perpendicular to the bottom plate 11. Each of the two pivot pieces 111 defines a cutout 1113. The cutout 1113 includes a wide portion 1111 and a narrow portion 1112. The wide portion 1111 has a first extending direction. The narrow portion 1112 has a second extending direction. In one embodiment, the first extending direction is substantially vertical, and an obtuse angle is defined between the first extending direction and the second extending direction. A positioning piece 115, between the two pivot pieces 111, is located on the bottom plate 11, to block the airflow guiding duct 30 in a particular location.
The rear plate 13 defines a ventilation area 131 and two apertures 132 at two corners of the ventilation area 131. Two latch pieces 133 extend from an edge of each of the two apertures 132. Each of the two latch pieces 133 defines a latch hole 1331. The two latch pieces 133 are parallel to each other and perpendicular to the rear plate 13. The rear plate 13 further defines two positioning holes 137 located on opposite sides of the ventilation area 131. A first distance between the two latch pieces 133 is substantially equal to a second distance between the two positioning holes 137.
The airflow guiding duct 30 includes a frame 31, a top wall 32, a bottom wall 33, and two sidewalls 35. The frame 31 defines an opening 311. The top wall 32 and the bottom wall 33 extend from opposite sides of the frame 31. The two sidewalls 35 extend from the other two opposing sides of the frame 31. The fan 50 can be secured to the frame 31 via a plurality of locking members 60 and is surrounded by the top wall 32, the bottom wall 33, and the two sidewalls 35. The airflow guiding duct 30 guides an airflow from the fan 50 through the opening 311 to the chassis 10. The airflow guiding duct 30 further includes two pivot posts 351 and two resilient pieces 353. A pivot post 351 protrudes from each of the two sidewalls 35. The resilient pieces 353 extend from the sidewalls 35. A protrusion 3531 is located on distal end of each of the two sidewalls 35. A positioning tab 355 extends from each of the two sidewalls 35. A third distance between the two resilient pieces 353 is equal to the second distance. A fourth distance between the positioning tabs 355 is equal to the second distance.
Referring to
In disassembly, the two resilient pieces 353 are resiliently deformable to allow disengagement of each protrusion 3531 from each latch hole 1331. The airflow guiding duct 30 is rotated around the two pivot posts 351 in a second direction opposite to the first direction, until each protrusion 3531 disengages from the latch pieces 133, thus the airflow guiding duct 30 is in the second position. The airflow guiding duct 30 is easily detachable from the chassis 10.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
