Abstract

High capacity DASD files used in many computer and workstation applications have stringent operating temperature constraints. Machine packaging and DASD accessibility often impose requirements that conflict with the ideal cooling design. The figure illustrates the disclosure of a housing with two integral fans that provide efficient cooling for DASD units while offering easy customer accessibility. DASD units slide in and out of the open end of the housing opposite the closed end (c). The illustrated cooling flow is created by one fan (a) pushing cool air into the housing and the other (b) pulling heated air out of the housing. The push-pull arrangement creates an efficient path by minimizing air loss that would normally leak out an open end if only one fan were used.

Cooling Housing for Direct Access Storage Device (DASD)

      High capacity DASD files used in many computer and workstation
applications have stringent operating temperature constraints.
Machine packaging and DASD accessibility often impose requirements
that conflict with the ideal cooling design.  The figure illustrates
the disclosure of a housing with two integral fans that provide
efficient cooling for DASD units while offering easy customer
accessibility.  DASD units slide in and out of the open end of the
housing opposite the closed end (c).  The illustrated cooling flow is
created by one fan (a) pushing cool air into the housing and the
other (b) pulling heated air out of the housing.  The push-pull
arrangement creates an efficient path by minimizing air loss that
would normally leak out an open end if only one fan were used.
