The thermal conductivity indicates the strength of heat conduction, representing the heat flux per unit temperature gradient. The convective heat transfer coefficient reflects the system’s ability to conduct heat by convection; the higher this value, the faster the convective heat transfer rate. Its value equals the convective heat transfer rate per unit area of heat transfer per unit temperature difference.

The thermal conductivity indicates the strength of heat conduction, representing the heat flux per unit temperature gradient. The convective heat transfer coefficient reflects the ability of a system to transfer heat by convection; the higher this value, the faster the convective heat transfer rate. Its value equals the convective heat transfer rate per unit area of heat transfer per unit temperature difference.
The thermal conductivity is one of the important parameters that reflect a material’s heat conduction properties. Its value represents the amount of heat transferred per unit area per unit time when there is a temperature difference of one unit between two planes separated by a unit length, and its unit is watts per meter-kelvin (W/m*K).
It refers to the amount of heat transferred per second through an area of 1 square meter, in a material 1 meter thick, under stable heat transfer conditions, when there is a temperature difference of 1 degree (K, °C) between its two surfaces.
It has good thermal conductivity, and its molecular vibration energy is relatively high
