<p><P>PROBLEM TO BE SOLVED: To provide a fan heat dissipator for reducing aerodynamic noise. <P>SOLUTION: The fan heat dissipator includes: a housing with a device air intake and a device air outlet installed therein; and a fan installed in the housing and having a fan intake and a fan outlet. A noise-reducing outlet is located adjacent to the fan outlet of the housing. A portion of airflow is discharged through the noise-reducing outlet in a process in which the airflow enters in the housing from the device air intake, passes through the fan intake and the fan outlet in turn, and is discharged from the device air outlet. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
