Embodiment Construction
[0030] Thermal resistance is a parameter that characterizes the heat dissipation capability of a device. It is the ratio of the temperature difference along the heat flow path of the device to the dissipated power that generates the temperature difference under the condition of thermal equilibrium, that is, the resistance on the heat conduction path, which means that the power heat of 1W is emitted during the heat conduction process. , the temperature difference between the two ends of the thermal circuit. According to the definition of junction-to-case thermal resistance, the parameters to be measured include junction temperature, case temperature and power dissipation. The shell temperature can be directly measured, and the power dissipation can be calculated by applying voltage and current.
