Abstract: Dynamically modifiable air movers can be modified during operation of a computing system to allow the performance of the fan (air flow, air flow split between exhausts) to be adjusted based on a workload being performed by the system. The physical modifications that an air mover can undergo are physical in nature and include adjusting the placement of one or more cutwaters, expanding or contracting an expandable portion of the fan housing, covering or uncovering an exhaust to provide or remove cooling to memory components, and moving a slidable strip to extend or withdraw from an exhaust. Causing one or more of these physical modifications to be made can be performed in response to the system determining that a temperature, rate of temperature change, power consumption level, rate of power consumption level change of the system or system components exceeds or has dropped below a threshold level.

The radiation shield includes a wall secured to the support structure, a vacuum bag on the wall, where the vacuum bag has an inside air pressure less than an air pressure outside the vacuum bag, and a lid. The air pressure inside the vacuum bag is less than the atmospheric pressure outside the vacuum bag. When the vacuum is created in the vacuum bag, the vacuum bag deforms and compresses to help provide a vacuum-based mechanical loading that helps to create an applied load on the one or more radiation sources by the lid.

Abstract: Low-profile fasteners with springs that are either integrated with the fastener or are a physically separate component can provide a more evenly distributed load to a heat transfer device, such as a vapor chamber or a heat pipe. The low-profile fasteners do not increase the height of the base of a mobile computing device as the spring and the portion of the fastener that extends past the spring fit within a recess or cavity of the heat transfer device. The spring can be a diaphragm spring, a wave spring, or another suitable spring. The use of low-profile fasteners with springs to fasten a heat transfer device to a mainboard may allow for designs with a smaller mainboard area, which can leave room for a larger thermal management solution (which can increase cooling capacity) and allow for a greater thermal design power for the system.
