<p>A communicaiton device is provided. The device includes the electronic apparatus. An exterior flue in the communication device runs through the two surfaces of the device. The two outer surfaces of the exterior flue are in contact with the outer environment by setting the exterior flue which extends from the crust of the communication device to the inner of the communication device in the communicaiton device. The heat produced by the electronic apparatus in the communication device is transferred to the crust of the communication device and the side wall of the exterior flue by radiation, conduction or the air convection in the inner of thecommunication device. Then The heat is transferred to the outer environment by radiation, conduction or the outer air convection of the crust of the communication device and the outer surface of the exterior flue. The heat emission area of the outer surfaces of the communication device is increased and the heat emission efficiency of the outer surfaces of the communication device is improved and the heat emission performance of the communication device is improved as a result of the existence of the exterior flue.</p> |
