Unraveling the Mystery of Equivalent Thermal Conductivities for Heat Pipe and Vapor Chambers
Keywords: vapor chamber, conductivity, heat pipe
Over the many years heat pipes and vapor chambers have been on the market there has been a sort of fog over what the effective conductivities of these devices is. Published numbers for these devices tend to be quite high, >100,000w/mk, and although achievable these numbers are not what a typical thermal conductivity would be in an electronics cooling application. Thermal resistances of these devices will be broken down to where the delta-t for a given application can be estimated and from the estimated delta-t an effective thermal conductivity can be calculated.
