Abstract:
1. A method for fabricating a thermal spreader, comprising: laminating a plurality of layer portions together to fabricate a mechanically flexible substrate; providing an internal channel within the mechanically flexible substrate, the internal channel configured for containing an electrically-conductive liquid, the internal channel being further configured to allow for closed-loop flow of the electrically-conductive liquid within the internal channel; integrating a pump with the mechanically flexible substrate; fabricating a plurality of rigid metal inserts; forming a plurality of extension portions on a surface of each rigid metal insert included in the plurality of rigid metal inserts; connecting the plurality of rigid metal inserts to the mechanically flexible substrate; and coating an electrically-conductive liquid contact surface of one or more of the plurality of rigid metal inserts with a layer of alkali silicate glass, the electrically-conductive liquid contacting surface of each rigid metal insert configured to contact the electrically-conductive liquid within the internal channel.
