System and method for vapor chamber directional heat dissipation for a piezoelectric keyboard assembly

A method of assembling a heat dissipation system integrated with a haptic piezoelectric keyboard for an information handling system comprising:

• disposing each of a plurality of piezoelectric sensors across one of a plurality of cavities formed between the piezoelectric sensors and a vapor chamber;
• affixing a contact foil layer operably coupled to the plurality of piezoelectric sensors to fix the position of each of the plurality of piezoelectric sensors with respect to the contact foil layer and edges of the cavities supporting the piezoelectric sensors;
• operably connecting a keyboard controller to each of the plurality of piezoelectric sensors via tracers on a surface of the contact foil layer to receive actuation signals and deliver return haptic feedback control signals to generate haptic events at keys of the haptic piezoelectric keyboard;
• affixing the contact foil layer to a bottom surface of a coversheet of an assembly of the haptic piezoelectric keyboard;
• affixing the vapor chamber to a base chassis formed of a C-cover and a D-cover to dissipate heat horizontally away from the coversheet and keys of the haptic piezoelectric keyboard;
• and
• operably connecting the controller to a processor.

An integrated heat dissipation system for a haptic piezoelectric keyboard of an information handling system comprising:

• a base chassis formed of a C-cover affixed to a D-cover to house the haptic piezoelectric keyboard assembly, a processor, and a vapor chamber support layer;
• the vapor chamber support layer thermally coupled to a haptic piezoelectric keyboard assembly and the processor to direct heat away from keys of the piezoelectric keyboard of the C-cover and toward a vertical edge of the base chassis;
• the piezoelectric keyboard assembly comprising:
• a plurality of piezoelectric sensors disposed across the vapor chamber support layer;
• a contact foil layer, for detecting deformation of one of the plurality of piezoelectric sensors and registering a keystroke, affixed to the plurality of piezoelectric sensors and the vapor chamber support layer and to provide a haptic feedback control signal to generate a haptic response to the keys of the piezoelectric keyboard;
• wherein the contact foil layer is affixed to a bottom surface of the C-cover.
