Transversely actuated piezoelectric bellows heatsink

摘要

A transversely actuated piezoelectric bellows heatsink (TAPBH) has a linkage that includes multiple rigid sections coupled by flexible joints. A first fixed support is affixed to a first end of the linkage, and a piezoelectric element is mechanically coupled to a second end of the linkage. A diaphragm is mechanically affixed to a first side of the linkage, and an air enclosure, having an open area, is affixed to the diaphragm. A second fixed support is mechanically affixed to a second side of the linkage. Cyclic power from the power supply causes the piezoelectric element to expand and contract to force the linkage to expand and contract in an analogous manner, thus causing the diaphragm to move in an amplified motion to cause air to enter and be expelled from the air enclosure via air valves.

1. A transversely actuated piezoelectric bellows heatsink (TAPBH) comprising:
a linkage, wherein the linkage comprises a plurality of rigid sections coupled by flexible joints; a first end of the linkage affixed to a first fixed support; a piezoelectric element mechanically coupled to a second end of the linkage; a diaphragm mechanically affixed to a first side of the linkage; an air enclosure having an open area affixed to the diaphragm; and a second side of the linkage, wherein a second fixed support is mechanically affixed to the second side of the linkage, wherein cyclic power from a power supply causes the piezoelectric element to expand and contract to force the linkage to expand and contract in an analogous manner, thus causing the diaphragm to move in an amplified motion to cause air to enter and be expelled from the air enclosure via air valves.
