Abstract
Provided is a heat transfer device which has a function of generating power through vibration of capillary grooves having a thin piezoelectric film deposited thereon, in addition to a heat transfer function of discharging heat transferred from a heating element to the outside.
Claims7
A heat transfer device comprising:
- a vaporization unit including multi-channel capillary grooves which vaporize a working fluid through heat transferred from an external heating element so as to generate vapor;
- and
- a condensation unit that condenses the vapor of the working fluid vaporized by the vaporization unit and then returns the condensed liquid to the vaporization unit,
- wherein the multi-channel capillary grooves have a piezoelectric thin film deposited thereon, and vibrate due to the vapor of the vaporized working fluid such that power is generated from the multi-channel capillary grooves.
