Understanding the mechanism of heat transfer and effectively dissipating heat is important! Here we introduce various methods for measuring thermal properties.
Due to factors such as "miniaturization = fanless design" and "widespread use of power devices = increased heat generation," thermal issues have become important. Thermal conductivity measurement can be broadly classified into two categories: "steady-state method" and "transient method." The steady-state method provides direct thermal conductivity values and requires relatively large samples. The transient method can measure thermal diffusivity and thermal effusivity, and it is possible to measure with relatively small samples. We provide further detailed explanations, so please take a look at the PDF download below. 【Characteristics of the "Steady-State Method" and "Transient Method"】 ■ Steady-State Method - Direct thermal conductivity can be obtained - Requires relatively large samples ■ Transient Method - Can measure thermal diffusivity and thermal effusivity - Can measure with relatively small samples - Requires specific heat capacity and density *For more details, please refer to the PDF document or feel free to contact us.
