Low Noise Air Cooling

There is described an arrangement of air inlets and outlets in opposing walls of a fan-cooled electronics housing, which arrangement provides increased cooling effectiveness with decreased noise.

In Fig. 1, a side cut-away view, a housing 1 having two sections 2 and 3 is shown. The larger section 2 contains the electronics which provide the main function of the device housed. Fan 4 is located in plate 5 which is connected to housing 1 by seals 6. Sections 2 and 3 are separated by the plate 5.

Air is taken in through grille 7, traverses the electronics in section 2, and is discharged into section 3. Air is discharged from section 3 of housing 1 through grille 8. The holes comprising grille 8 are misaligned with fan 4 to provide an acoustic baffle 9. Air passes through the housing, as indicated by stream lines
10.

The total air flow through housing 1 is improved as a result of eliminating the possibility of recirculation. The noise level is significantly reduced as a result of baffle 9.
