ABSTRACT:
An electronic device is provided having a bimetallic fluid circulator for circulating fluid coolant in relation to electrical circuitry to provide enhanced heat exchange. The fluid circulator includes a first thin sheet exhibiting a first coefficient of thermal expansion and the second thin sheet dissimilar from the first thin sheet and exhibiting a second CTE that is substantially different than the first CTE. The first and second thin sheets are bonded together. The first and second thin sheets expand and contract at different rates based on changes in temperature such that the first and second thin sheets change shape to create a fanning motion to circulate the fluid and thus cool the electrical device.
