MINIATURE ACTUATOR INTEGRATION FOR LIQUID COOLING

摘要

A device for cooling integrated circuits on circuit boards. A base placed proximate the element to be cooled contains an actuator that forces a cooling liquid through a plurality of channels that dissipate heat generated by the element. The base with the actuator, liquid and channels is sealed with a top. Preferred actuators are electric motors, and MEMS such as electrostatic actuators and piezoelectric actuators. The base has a large surface area relative to the thickness of the chamber The ratio of the surface area to thickness may range from about 40:1 to about 5:1.
