PRODUCT DEMO: MAGSIC™, Next Generation Thermal Solution for IGBT Modules

This presentation is intended to help understanding the features of MAGSIC™, latest thermal solution for IGBT from A.L.M.T. Corp. to the potential clients in the world.

As the solutions for global warming and carbon neutrality (decarbonization), electric railways that have excellent energy efficiency are getting attention. We developed a new heatspreader, MAGSIC™ that comes from the combination of Magnesium and Silicon carbide for the power modules that are used for high-speed railways. The thermal conductivity of MAGSIC™ is 230W/(m・K), Almost 30% higher than the conventional material Al-SiC, and only replacing it with MAGSIC™ can be reduced the thermal resistance of the power module by approximately 10%. Moreover, due to its excellent shape stability during the heat cycle, MAGSIC™ can keep superior initial contact for a long time. Therefore, it is expected to contribute to the high performance and long-term reliability of the IGBT modules for high-speed railways.

WEBINAR: Rather Be Cool Than Dead

All power supplies have operating ambient temperature limits, above which they need to be “derated” or run at reduced power to lower their internal heat dissipation.

The derating point and slope of the derating curve are dependent on many factors, such as the input voltage, the output current, the temperature of the most critical component, airflow and even the orientation of the power supply, to name a few.

Although sophisticated thermal flow modelling programs exist to calculate some of these factors, a real-life test with proven experimental data is more dependable and reassuring to the end customer, who can then reliably work out how far they can push the operating envelope of the power supply in their application without it overheating or going into thermal shutdown.

This webinar explains how RECOM uses a computer controlled wind tunnel to generate accurate, repeatable and authentic derating graphs automatically.

WEBINAR: Material(s) Matter(s) in Liquid Cooling Connectors

As various cooling designs and components evolve, the focus on materials that perform reliably is required. This presentation will provide a summary of metal versus polymer components and how they compare on durability/ruggedness, susceptibility to various types of corrosion, absorption/extraction, dimensional stability, cost, and weight. Various types of metal and plating will be examined along with PSU and PPSU. Presented information will challenge the assumption that stainless steel is always the best, or “safest,” option.

Ultimately, as liquid cooling technology grows in adoption and continues to evolve, the electrochemical nature of the systems necessitates deliberate focus on materials early on in order to ensure long-term performance and reliability. Thermal engineers can be better prepared to not only avoid catastrophic failures but ensure long-term performance and reliability.

WEBINAR: The Next Generation of Metal Thermal Interface Materials – Liquid Metal Pastes

For many years, metals have been used as thermal interface material (TIM) in the industry. Due to their high reliability and high thermal conductivity, the metal TIMs have been great solutions, especially for the most challenging applications. Thermal conductivity and interfacial resistance are the most important properties of a TIM. One of the biggest obstacles for using metal TIMs in applications is the interfacial resistance. Most of the current metal TIMs are quite stiff and require pressure to form seamless connection between materials and surfacing, to lower interfacial resistance. With devices becoming smaller, consuming more power, and producing more heat, finding the right TIM becomes one of the most critical steps in any application. Liquid metal pastes (LMPs) are developed to provide an enhanced metal TIM solution that combines high thermal conductivity and lower interfacial resistance, compared to common metal TIM options in the market. Furthermore, it offers additional benefit as it is liquid metal nature but better: it allows low and controlled bondline thickness, can be applied by jetting or dispensing, and a higher viscosity that survive pressure without leaking.

WEBINAR: Introduction to Carbon Fiber-Orientated Thermal Gap Filler

Thermal gap filler conductivity has increased dramatically over the last 10 years. The ever-increasing power and smaller area have driven the need for higher conductivity thermal gap fillers. In order to increase thermal conductivity, Fujipoly has explored various thermal fillers to achieve ultra-high thermal conductivity. One of those fillers is Carbon fiber.

In this webinar, we will look at the need for higher conductivity materials and how carbon fiber-oriented thermal gap fillers can meet the demand for higher heat flux. Carbon fiber-oriented thermal gap fillers exhibit very low thermal resistance while still offering a highly compressible thermal gap filler. We will explore some of the properties of carbon fiber-oriented gap fillers as well as best practices for implementing them. We will discuss how they can be a great option when more conventional thermal gap fillers are not proving the thermal resistance or compliance needed.

WEBINAR: Model Based Optimization of Electric Vehicle Power Control Units (PCUs)

On the path towards a decarbonized society, the automotive industry is shifting to electric vehicles worldwide. Power control units (PCUs), which consist of inverters and DCDC converters, convert the battery’s electric power from DC to AC and supplies power to the electric motor. Therefore, PCUs are an important component of electric vehicles, equivalent to the IC engine of gasoline vehicles.

Thermal management associated with the losses generated by power conversion is an important design issue for PCUs. Physics based thermal modeling and simulation can be utilized to identify potential thermal problems early in the design process and develop reliable cooling solutions. The cooling solutions can include for example, the development of a new water-cooling system to deal with the increased losses in power devices, the design of a heat sink that meets the required specifications, and the front-loading design for thermal management of control boards.

By combining the latest technologies in CFD, optimization, and machine learning, it is possible to achieve rapid design space exploration, optimization, and modeling for system level design. More importantly, physics based thermal models allow for digital testing & design optimization even before physical prototypes are available for physical testing. These models can live through the entire design life cycle of the PCU, adding more details & complexity as the design matures. When the design is transferred to production, the same models can be used to respond faster to manufacturing challenges, material supply chain disruptions and other adverse events that may require a redesign of the cooling solution.

PRODUCT DEMO: Using the Angstrom Method to Measure Effective Thermal Diffused Conductivity of Vapor Chamber

This instrument discusses how to measure the effective radial thermal conductivity of the vapor chamber by using the Angstrom method. The thermal diffusivity of the two ultra-thin vapor chambers VC-D and VC-E developed in the T-Global company are αVC-D=1.9(cm2/s) and αVC-E =1.44(cm2/s). Keff,D=4833 (W/m.K) and Keff,E=3069 (W/m.K) are converted to equivalent effective thermal conductivity, which is about ten times that of pure copper.

In order to prove the Angstrom method’s accuracy for measuring the effective thermal conductivity of the Vapor Chamber, one may penetrate vapor chambers D & E with a sharp screwdriver and expel all the water out of the chamber, hence, these two vapor chambers were thus become to be two copper plates, measure the thermal conductivities of these two copper plates again, the K value we get were 370.18 (W/m.k) and 379.8 (W/m.k) respectively, and that was quite close to the pure copper mater K value 400(W/m.k). The repeatability error of the experiment data is less than 5%, and the accuracy error is less than 10%.
