The thermal resistance of a heat sink is one of the key indicators for evaluating the performance of a heat sink. The lower the thermal resistance, the better the heat transfer capability of the heat sink.

Thermal resistance testing is usually performed using either the thermal conduction method or the thermal resistance method. The thermal conduction method evaluates the thermal conductivity of a material by measuring the rate at which heat is conducted through the material. The thermal resistance method calculates the thermal resistance value by measuring the temperature difference and heat flow between the two sides of the material.

As a global manufacturer and supplier of heat sinks, Lori provide professional heat sink thermal resistance testing services. Heat sink thermal resistance testing not only measures the total thermal resistance of a heat sink, but also analyzes the individual components of the heat sink. We can pinpoint the radiator's heat dissipation surface and heat radiation area through the professional heat sink thermal resistance test instrument, and further find out the reasons for the poor heat dissipation effect of the heat sinks. In addition, it is possible to compare different types and materials of heat sinks, thus providing the user with a basis for optimizing the design of the heat sink.
