... 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...
