Abstract
A portable electronic device includes a main body and a centrifugal fan. The main body includes a bottom wall, an opposite top wall and a side wall connecting the top wall with the bottom wall. The bottom wall, the top wall and the side wall cooperatively define a space in the main body. A groove is defined in the top wall for communicating the space with an outside environment of the main body. The top wall is provided with an active cover plate corresponding to the groove. The cover plate is capable of moving upwardly relative to the top wall to define an air intake between the cover plate and the top wall. A centrifugal fan is received in the space of the main body. The centrifugal fan sucks air into the space from the outside environment via the air intake and the groove.
