Benefits of technology

The present patent relates to an air blocking apparatus for a server that can improve heat dissipation efficiency. The apparatus includes a bottom plate, a blocking plate, and two ribs to prevent deformation of the blocking plate. The apparatus can be fixed in a chassis when the heat sink is removed. The blocking plate has a vent to provide the same airflow resistance as the fin assembly of the heat sink. The technical effect of the invention is to avoid significant redistribution of airflow through the chassis and decrease heat dissipation efficiency.

Problems solved by technology

Therefore, the empty zones in the server will possibly decrease heat dissipation efficiency in the server.

Embodiment Construction

[0009]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.

[0010]Referring to FIGS. 1 and 2, an exemplary embodiment of an air blocking apparatus can be installed in a server chassis 800, where a heat sink 200 is installed. The chassis 800 defines a plurality of locating holes 801. The heat sink 200 includes a base board 201, and a fin assembly 202 formed on a top side of the base board 201. The base board 201 defines a plurality of mounting holes 2011 to align with the corresponding locating holes 801, thereby allowing a plurality of fasteners, such as rivets or screws, to extend through the mounting holes 2011 and the corresponding locating holes 801 to fix the heat sink 200 to the chassis 800. The fin assembly 202 includes a plurality of fins 203 all paral...

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

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to an air blocking apparatus of a server.[0003]2. Description of Related Art[0004]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.BRIEF DESCRIPTION OF THE DRAWINGS[0005]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 vi...
