Flexible service air baffle

A baffle is provided that is usable in an information handling system. The information handling system may have a first compartment at a first elevated pressure that is higher than an ambient pressure and a second compartment at a second elevated pressure that is higher than the ambient pressure. Further, a region adjacent to the first and second compartments and in fluid communication therewith may be operable to receive a removable baffle therein. When the baffle is inserted into the region, it may be operable to maintain the region at a third elevated pressure that is higher than the ambient pressure. However, when not inserted into the region, the baffle may be foldable into a substantially flat shape.

Pressure sensitive adhesive with thermally conductive release tab

Computing devices may require disassembly to repair or replace a defective or damaged component, or to facilitate recycling at the end of the computing device's service life. While pressure sensitive adhesive (PSA) is good at creating secure connections between components within the expected operating conditions of the computing device, PSA resists intentional disassembly of such components. The presently disclosed PSA with thermally conductive release tabs provides a mechanism for effective spot-cooling of the PSA between adhered components. Once the PSA reaches a low temperature threshold, one component may be mechanically separated from another component. This yields potentially faster and easier disassembly of adhered components than prior art techniques.
