1. Technical Field
The present disclosure relates to heat dissipation in an electronic device, and particularly, to an airflow guide for heat dissipation applied in an electronic device.
2. Description of the Related Art
An electronic device (for example, a computer or a server) can consist of many parts such as a disk drive, a power supply, a motherboard and electronic components such as memory, IC components, CPU (central processing units), and others, assembled on the motherboard. Heat generated by the electronic components of the electronic device requires prompt dissipation. As performance parameters of the components increase, the generated heat increases commensurately. Therefore, the electronic device usually includes a fan, which is provided with an airflow guide, to dissipate the heat generated by the electronic components.
A typical airflow guide is fixed in a computer case, and a fan is provided with the airflow guide to dissipate excess heat. The airflow guide can be disposed on the CPU and the power supply. The airflow guide includes a top cover and two side covers. The side covers extend perpendicular to opposite ends of the top cover respectively. The side covers and the top cover cooperatively define an air inlet adjoining the CPU and an air outlet adjoining the power supply. However, for different sizes of electronic components, various airflow guides having different configurations may be required. For example, a single-core CPU and a dual-core CPU require different lengths of the airflow guide.
Therefore, there is room for improvement within the art.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views, and all the views are schematic.

The first top plate 11 is substantially rectangular, and includes two engaging portions 112 and a receiving portion 115. The two engaging portions 112 are defined in opposite sides of the first top plate 11 respectively. In the illustrated embodiment, each engaging portion 112 is a T-shaped groove. The receiving portion 115 is defined in the adjoining side of the first top plate 11. The second top plate 13 is at least partially received in the receiving portion 115. The first top plate 11 further defines two positioning holes 113 in the opposite sides of the first top plate 13 adjacent to the two engaging portions 112. The two positioning holes 113 communicate with the receiving portion 115.
The second top plate 13 is substantially rectangular, and includes two limiting pins 131 arranged at opposite sides of the second top plate 13. The two limiting pins 131 are received in the two positioning holes 113 of the first top plate 11. The second top plate 13 defines two positioning holes 132 in the opposite sides of the second top plate 13. The second top plate 13 further defines a receiving groove 135 in a side of the second plate 13 adjacent to the two positioning holes 132. The receiving groove 135 communicates with the two positioning holes 132.
The third top plate 15 is substantially rectangular, and includes two limiting protrusions 151 arranged at opposite sides of the third top plate 15. The two limiting protrusions 151 are respectively received in the two positioning holes 132 of the second top plate 13.

The base plate 21 is substantially rectangular, and defines two positioning holes 212 in opposite sides of the base plate 21 and a holding portion 215 in the other adjoining side of the base plate 21. The two positioning holes 212 communicate with the holding portion 215. The sliding plate 23 is at least partially received in the holding portion 215. The base plate 21 further includes two fixing portions 213 disposed in opposite ends of one of the opposite sides of the base plate 21 adjacent to the holding portion 215. The two fixing portions 213 are received in the corresponding engaging portions 112 of the first top plate 11. In the illustrated embodiment, each fixing portion 213 is a T-shaped protrusion.
The sliding plate 23 is substantially rectangular, and includes two limiting shafts 231 and two connecting portions 232. The two limiting shafts 231 are disposed on opposite ends of a side surface of the sliding plate 23 away from the connecting portions 232. The two connecting portions 232 are disposed on two adjoining corners of an outer surface of the sliding plate 23. Each connecting portion 232 defines a shaft hole 235.
The revolving plate 25 is substantially rectangular, and includes two revolving shafts 251. The two revolving shafts 251 are disposed on opposite ends of the revolving plate 25, and received in the two shaft holes 235 of the sliding plate 23, respectively.

It is to be understood that the engaging portion 112 of the first top plate 11 can also be a latching groove, and correspondingly, the fixing portion 213 of the base plate 21 is a hook received in the engaging portion 112 in the form of the latching groove. The revolving plate 25 can also be rotatably connected to the sliding plate 23 by a hinge. The third top plate 15 and the revolving plate 25 can also be omitted.
Finally, while the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
