Abstract
An air blocking apparatus is mounted to a server to replace a heat sink. The heat sink includes a base plate, and a fin assembly formed on the base plate. The fin assembly comprises a number of parallel fins. An air passage is defined in every two neighboring fins. The air blocking apparatus includes a bottom plate and a blocking plate perpendicularly extending up from the bottom plate. The blocking plate is rectangular, with a width and a height of the blocking plate respectively equal to a width and a height of the fin assembly of the heat sink. The blocking plate defines a vent. An area of the vent is equal to a sum of cross sectional areas of all of the air passages taken along a direction perpendicular to the board plate.
Description
- 1. Technical Field
- The present disclosure relates to an air blocking apparatus of a server.
- 2. Description of Related Art
- A server may have many processors, and heat sinks mounted on the processors for heat dissipation. For various reasons, some of the processors in a server may be removed and not replaced, leaving empty zones in the server. Heat-dissipating airflows tend to flow through the empty zones with low airflow resistance, rather than flow through the heat generating components in the server. Therefore, the empty zones in the server will possibly decrease heat dissipation efficiency in the server.
- Many aspects of the present 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 present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an isometric, exploded view of an exemplary embodiment of an air blocking apparatus, a server chassis, and a heat sink. -
FIG. 2 is a sectional view of the heat sink ofFIG. 1 , taken along the line of II-II. -
FIG. 3 is side plan view of the air blocking apparatus ofFIG. 1 . - The 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.
- Referring to
FIGS. 1 and 2 , an exemplary embodiment of an air blocking apparatus can be installed in aserver chassis 800, where aheat sink 200 is installed. Thechassis 800 defines a plurality of locatingholes 801. Theheat sink 200 includes abase board 201, and afin assembly 202 formed on a top side of thebase board 201. Thebase board 201 defines a plurality ofmounting holes 2011 to align with the corresponding locatingholes 801, thereby allowing a plurality of fasteners, such as rivets or screws, to extend through themounting holes 2011 and the corresponding locatingholes 801 to fix theheat sink 200 to thechassis 800. Thefin assembly 202 includes a plurality offins 203 all parallel to thebase board 201, and twoheat pipes 204 extending through thefins 203. Air can flow throughair passages 207 defined between neighboringfins 203 for heat dissipation. A sum of the cross sectional areas of all of theair passages 207 taken along a direction perpendicular to theboard plate 201 labeled II-II is equal to (W×h)×(N−1), wherein W stands for the width of each of thefins 202, h stands for the distance between neighboringfins 203, and N stands for the quantity of thefins 202. - Referring to
FIGS. 1 and 3 , the air blocking apparatus includes abottom plate 10, ablocking plate 20 perpendicularly extending up from thebottom plate 10, and tworibs 30 connected between thebottom plate 10 and theblocking plate 20 to prevent the blockingplate 20 from being deformed. A plurality offixing posts 11 extends downwards from thebottom plate 10. When theheat sink 200 is removed from thechassis 800, the air blocking apparatus can be fixed in the chassis 100, with thefixing posts 11 engaging in the corresponding locatingholes 801 of thechassis 800. Theblocking plate 20 is rectangular, with a width and a height respectively equal to the width and the height of thefin assembly 202 of theheat sink 20. The blockingplate 20 defines avent 21. An area of thevent 21 is equal to the sum of the cross sectional area of theair passages 207, to make resistance to airflow provided by theblocking plate 20 the same as airflow resistance provided by thefin assembly 202 of theheat sink 200. Therefore, when the air blocking apparatus is mounted in thechassis 800 to replace theheat sink 200, lower heat dissipation efficiency caused by significant redistribution of airflow through thechassis 800 can be avoided. - It is to be understood, however, that even though numerous characteristics and advantages of the embodiment have been set forth in the foregoing description, together with details of the structure and function of the embodiment, 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.
