In theory, heat pipe thermal conductivity can range from 4,000 to 100,000 W/m-K. In reality, the range for electronics cooling appliions is more like 1,500 to 50,000 W/m-K. This is still an enormous improvement over the thermal conductivity of solid copper (390 W/m-K) or solid aluminum (200 W/m-K). This difference makes heat pipes an
Materials”. PPI’s Technical Report 3 (TR-3) describes the methodology for establishing a pipe material’s hydrostatic design basis. The hydrostatic design basis, HDB, for a thermoplastic materials is the long-term hoop tensile stress that the material can be expected to withstand for 100,000 hours at a specific temperature.
