I don't understand why they are blowing air over the chip - why not use a https://en.wikipedia.org/wiki/Heat_pipe https://en.wikipedia.org/wiki/Heat_pipe ? They can be made extremely thin and work much better than air.
Maybe even combine the piezoelectric idea with a heat pipe to increase thermal flow.
- ororroro 4y agoThe diagram is misleading. The use case seems to be to directly vent air from the device which already has a passive cooling design. Drawing that air from near the chip maximizes the temperature delta and thus efficiency. Not sure how novel it is considering things like https://www.curiejet.com/en/product/micro-pump/air-pump-and-micro-blower https://www.curiejet.com/en/product/micro-pump/air-pump-and-... already exist.
