LOW-PROFILE FASTENERS WITH SPRINGS FOR HEAT TRANSFER DEVICE LOADING

AbstractLow-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.
