MIT Researchers Developed New Heat Conducting Polymer Films

MIT Researchers Developed New Heat Conducting Polymer Films Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat. Now MIT engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat — an ability normally associated with metals. In experiments, they found the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic. Read more »

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze or shut down. Researchers at the University of Illinois at Urbana-Champaign and The University of Texas, Dallas have collaborated to optimize the crystal-growing process of boron arsenide – a material that has excellent thermal properties and can effectively dissipate the heat generated in electronic devices.

Litecool Turns LED Packaging on Its Side

Litecool's new packaging concept significantly reduces the thermal resistance of LED packages by using a vertical dielectric Litecool has produced LED packages in a vertical orientation rather than horizontal. This means that the dielectric layers only have a minor impact on the thermal performance of the LED package and allow the heat to escape more effectively through the metallic parts of the package. This has significant benefits for flip-chip packaging where dielectric layers are usually very close to the diode. Read more »

NRL Researchers Discover Novel Material for Cooling of Electronic Devices

Schematic of thermal management in electronics: Local temperature increases occur as a result of current flow in active regions of devices and can lead to degradation of device performance. Materials with high thermal conductivities are used in heat spreading and sinking to conduct heat from the hot regions. (Photo: U.S. Naval Research Laboratory)  A team of theoretical physicists at the U.S. Naval Research Laboratory (NRL) and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date.

LED – Cooling and Thermal Management

Figure 4 - Often as an application specific heatsink, it is best to use an adapted standard heatsink. As we all know, the life span of an LED depends on the semi-conductor material used as well as the current/heat relationship. The light output of the LED becomes weaker and weaker and once it reaches 50% of its initial value, the life expectancy of the LED has, by definition, been reached. A life span of a few hundred and up to 100,000 hours is possible, but only when avoiding high temperatures which drastically reduce the length of the LED’s life. Read more »
