Description

Technical field [0001] The invention relates to the field of solid thermophysical property testing, in particular to a device for measuring the thermal conductivity of a heat pipe. Background technique [0002] A high-quality heat pipe has a thermal conductivity that exceeds any known metal. Therefore, the application of heat pipe technology in engineering is becoming more and more popular, not only has achieved significant results in waste heat recovery and energy saving, but also has shown strong vitality in the upgrading of traditional heat and mass transfer equipment and the cooling of non-traditional electronic components. This requires a safe, reliable, easy-to-operate, high-accuracy, and wide-ranging equipment that can measure the thermal conductivity of the heat pipe. [0003] According to the literature, there have been several methods for measuring the heat transfer performance of heat pipes or heat pipe heat exchangers. However, different measurement methods are still ...
