Abstract
A heat dissipation system of a portable electronic device is provided. The heat dissipation system includes a body and at least one fan. A heat source of the portable electronic device is disposed in the body. The fan is a centrifugal fan disposed in the body. The fan has at least one flow inlet, at least one flow outlet, and at least one spacing portion. The flow outlet faces toward the heat source, and the spacing portion surrounds the flow inlet and abuts against the body, so as to isolate the flow inlet and the heat source in two spaces independent of each other in the body.
