High Performance Heat Transport Device utilizing Phase Change (Application to Heat Spreader for Electronic Device Cooling)
The higher performance of the electronic devices causes the higher heat generation density, and it requires the high performance cooling technology. So far, this cooling is performed by using fins (extended heat transfer surfaces). We are inventing a new heat transport device utilizing phase change (evaporation/condensation) which can give much higher heat transport performance due to the convective and latent heat transfer.
