... going through and a side channel which is open to the ambient. A convex meniscus is formed in side channel near the T-junction, evaporating/volatizing into the ambient. The consumption of water due to the evaporation is compensated by the supply from the main channel. It is found that for weak...

... of the vapor chambers are all 95mm*70mm*3.2mm. A remote method was used to test the performance of the vapor chambers, where the property of evaporation and vapor transportation will be mainly studied. Results show that the adiabatic resistance (vapor transportation) can be less than 0.05°C/W at high heat flux...
