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. |
