In some embodiments, a piezoelectric actuator is coupled to a blade having a rake shape. The blade may include a base with two or more prongs extending therefrom. At least a portion of one or more prongs may be positioned between the fins of a heat sink. Other embodiments are disclosed and claimed.
1. An apparatus, comprising:
a single piezoelectric actuator;
a blade having a rake shape coupled to the actuator and including a base portion with flat prongs extending therefrom in a same plane; and
a heat sink having a base and a plurality of protruding fins,
wherein at least a portion of the flat prongs is positioned between the fins of the heat sink at an angle that is transverse to a plane of the base of the heat sink.
2. The apparatus of claim 1 , wherein at least one prong includes an edge having one or more notches along the edge.
3. The apparatus of claim 1 , wherein at least one prong includes a hole through the prong.
