A heat dissipating device includes a housing and a fan unit. The housing has a top wall, a bottom wall opposite to the top wall, and a lateral wall that interconnects the top and bottom walls. Each of the top, bottom and lateral walls is formed with at least one vent hole therethrough. The fan unit is mounted in the housing for circulating air within the housing. The fan unit is operable so as to allow cool air to flow into and heated air to flow out of the housing through the vent holes in the top, bottom and lateral walls.
