Heat Spreading

Presently, many methods are adopted to reduce the junction-to-case thermal resistance (Rjc) of insulated-gate bipolar transistor (IGBT) modules in order to increase their power density. One of these approaches is to enhance the heat spreading capability of the base plate (heat spreader) of an IGBT module using a vapor chamber (VC). In this paper, both experimental measurement and thermal modeling are conducted on a VC-based IGBT module and two copper-plate-based IGBT modules. The experimental data show that Rjc of the VC-based IGBT module decreases substantially with the increase in the heat load of the IGBT. Rjc of the VC-based IGBT module is ∼50% of that of the 3 mm copper-plate-based IGBT module after it saturates at a heat load level of ∼200 W. The transient time of the VC-based IGBT module is also shorter than the copper-plate-based IGBT modules since the VC has higher heat spreading capability. The quicker responses of the VC-based IGBT module to reach its saturated temperature during the start-up can avoid a possible power surge. In the thermal modeling, the vapor is substituted as a solid conductor with extremely high thermal conductivity. Hence, the two-phase flow thermal modeling of the VC is simplified as a one-phase thermal conductive modeling. A thermal circuit model is also built for the VC-based IGBT module. Both the thermal modeling and thermal circuit results match well with the experimental data.

One example of the growing information technology today is mobile learning, mobile learning which refers to mobile technology as a learning medium. Mobile learning is learning that is unique for each student to access learning materials anywhere, anytime. Mobile learning is suitable as a model of learning for the students to make it easier to get an understanding of a given subject, such as math is pretty complicated and always using formulas.The design method that I use is the case study method, namely, learning, searching and collecting data related to the study. While the development of engineering design software application programs that will be used by the author is the method of Rapid Application Development (RAD), which consists of 4 stages: Requirements Planning Phase, User Design Phase, Construction Phase and Phase Cotuver.
