Question: What is the physical meaning of the heat transfer coefficient? Answer: The physical meaning of the heat transfer coefficient K is the amount of heat transferred by a fluid per unit area and per unit time for every one-degree change in temperature; that is, K = Q/SΔTm. The unit is W/m2·°C. Where: Q represents the heat transfer rate, in W ； S --- heat transfer area, m2 △tm--- average temperature difference,℃
The heat transfer coefficient was previously referred to as the overall heat transfer coefficient. **The current standard specifications uniformly refer to it as the heat transfer coefficient. The heat transfer coefficient K value refers to the amount of heat transferred per square meter in one hour under stable heat transfer conditions, when there is a temperature difference of 1 degree (K, °C) between the air on either side of the building envelope; the unit is watts per square meter per degree (W/㎡·K, with K being replaceable by °C).
The heat transfer coefficient K value refers to the amount of heat transferred per square meter in 1 hour under stable heat transfer conditions, when there is a temperature difference of 1 degree (K, °C) between the air on either side of the building envelope; the unit is watts per square meter per degree (W/㎡·K, with K being replaceable by °C)
The physical meaning of the heat transfer coefficient K is the amount of heat transferred per unit time through a unit area of heat transfer when there is a temperature difference of 1 K between two fluids; its unit is J/(s·m·K)

The thermal conductivity represents the ability to conduct heat; it is a thermal property of a material, and numerically it equals the heat flux per unit temperature gradient. The higher the thermal conductivity, the faster the heat conduction.
