Rogers Corp has announced the expansion of its line of HeatSORB phase change materials, the company’s proprietary thermal management solutions for high-end portable electronics. HeatSORB is a unique material capable of consistently absorbing large amounts of heat within a very specific temperature window. The newest additions to the portfolio give designers more options for application-specific challenges.
As today’s portable device users demand greater performance and functionality, smartphones and other devices generate more and more heat that must be dissipated in some way. Maintaining acceptable chipset, battery and skin temperature is becoming a critical design challenge. Conventional heat dissipation methods can be insufficient, particularly when dealing with heat surges.
Overheating, negatively impacts the user experience as well as device performance and component life. Rogers’ HeatSORB materials are designed to capture heat generated by electronic components, allowing the device to remain cool for the user. When the device is not in use, HeatSORB releases the thermal energy and regains its ability to absorb heat in the next cycle.
Since the product’s initial introduction, designers have been using the material to delay temperature rise. The newest offerings, available in 37C phase change temperature in three thicknesses (0.2, 0.3, and 0.4mm), are designed to address heat surge challenges in device areas that touch or are close to the human body – areas where the sensation of warmth is more sensitive, such as the ear or the face. Potential applications for the new materials include wearable devices, smart phones, tablets, and other devices where heat surge management is a challenge.
