What Is Thermal Resistance?

Thermal resistance refers to the ratio between the temperature difference between the ends of the object and the power of the heat source when heat is transmitted on the object. The unit is Kelvin per watt (K / W) or Celsius per watt (° C / W).

Thermal resistance

When heat is transmitted on the object, the ratio between the temperature difference between the two ends of the object and the power of the heat source, the unit is Kelvin per watt (K / W) or Celsius per watt (° C / W), that is,

In the above formula,

Is the temperature at one end of the object,

The temperature of the other end of the object and

Is the power of the heating source.

When heat is inside an object

The resistance of heat on the heat flow path reflects the size of the heat transfer capacity of the medium or between the medium, indicating that the 1W heat caused

The resistance of microorganisms to heat is called heat resistance, which refers to the lethal time of microorganisms under certain conditions (mainly temperature). Relative thermal resistance is the ratio of the lethal time of a microorganism under a certain condition to the lethal time of another microorganism under the same conditions. ^[2]
