By Norman Quesnel Senior Member of Marketing Staff Advanced Thermal Solutions, Inc. (ATS) Electric vehicles (EV) fall into two main categories: vehicles where an electric motor replaces a combustion engine and vehicles that feature a combustion engine assisted by an

electric motor.

They are relatively inexpensive, once a design is made the manufacturing is highly automated, and, in most cases, aluminum is the material used.

PUSH PIN HEAT SINKS

Push pin material available in 10 sizes from 9-20mm in length. Lightweight, aluminum HS extruded from AL6063 for optimal heat transfer and finished with blue anodization. Heat sinks pre-assembled with phase-changing material for increased thermal performance. Double-sided thermal tape and no TIM options available to meet application specific THERMAL INTERFACE MATERIAL Advanced Thermal Solutions, Inc. (ATS) engineers have received several questions from customers about the phase-change material that comes standard on the base of all ATS heat sinks. Engineers have asked whether imperfections on the surface of the grey foil that protects the phase-change material, such as dents or wrinkles, have a significant impact on the thermal interface material

THERMAL RESISTANCE

R TIM is the thermal resistance of the thermal interface material. R f is the total thermal resistance through the fins. The final term in Equation 1 represents the resistance of the fluid, e.g. air, going through the heat sink where m is the mass flow rate and C p is the heat capacity of the fluid. As Equation 2 shows, R cond and R conv are 5G DEVICES AND THERMAL MANAGEMENT By Norman Quesnel, Senior Member of Marketing Staff Advanced Thermal Solutions, Inc. (ATS) Qpedia 107, Featured Article.

THERMAL RESISTANCE

Figure 5 shows a graph of the total thermal resistance of the heat sink, R hs and spreading resistance, R s as a function of base thickness for copper and aluminum material. (Note that the final term from Equations 1 and 10 is ignored because it is constant and does not contribute to the understanding of spreading resistance).
