Abstract

The present application describes a computer server. The computer server includes a plurality of layers of fixed plates each having at least one corresponding component provided thereon. An air inlet and an air outlet are provided on side panels of an outer shell of the server case. A first set of fans is provided on an inward-facing side of the air inlet, and a second set of fans is provided on an inward-facing side of the air outlet. The first set of fans and the second set of fans generate a high-pressure airflow from the air inlet to the air outlet. The computer server further comprises at least one first heat sink and a second heat sink, wherein the at least one first heat sink is connected to a heat generating component on the plurality of layers of fixed plates.
