Overview

Meet Growing Thermal Challenges in Mobile Devices Using GORE® Thermal Insulation
GORE Thermal Insulation can help you beat the heat!
See three ways to improve your existing solution … with no compromises.

The demand for greater performance, functionality, and smaller form factors is increasing thermal challenges in mobile devices, particularly as many powered components are generating more heat in smaller spaces. More heat generation requires advanced thermal conductivity designs to spread heat more evenly across the surface of the device.

GORE Thermal Insulation is an innovative thermal management solution that increases design flexibility and the designer’s ability to direct heat through greater control of z-axis thermal conductivity.

Improved z-axis control means superior spreading options that enable components to:

  • perform at higher levels for longer periods,
  • accommodate shrinking form factors,
  • meet surface temperature requirements.

How We Help You Beat the Heat

Effective Thermal Management With Enhanced Thermal Spreading
The Effect Insulation Has on Heat Transfer
Crayons — with and without GORE Thermal Insulation — melt at different rates.

Thermal engineers use graphite, heat pipes and vapor chambers to spread and dissipate heat across a larger area to improve device performance. As thermal spreading requirements increase, these thermal designs can still fail to reduce hot spots due to insufficient thermal resistance in the z-direction, which reduces the spreading ratio and increases prevalence of hot spots.

 

 

 

 

With GORE Thermal Insulation, you can now improve the effectiveness of your thermal spreading solutions. Our insulating laminates for electronics have a through-plane thermal conductivity (kz) significantly lower than that of air. Enabled by premium aerogel technology, GORE Thermal Insulation will enhance the heat-spreading ratio and outperform system-level air gaps. It can be used independently or in conjunction with heat spreaders to create a higher-performing thermal design.

 

 

 

 

 

Comparison: Effectiveness of Thermal Spreading With and Without GORE Thermal Insulation

GORE Thermal Insulation increases the designer’s ability to direct heat by enabling greater control of z-axis thermal conductivity. More control means superior spreading options and more design flexibility. Combining GORE Thermal Insulation with graphite for example — one of many possible configurations — allows for more graphite to be included, as a thinner amount of insulation can be used to provide the same thermal resistance as a thicker air gap. Added graphite capacity in the system allows for components to be utilized at higher power outputs, as the additional generated heat can be directed away from the component.

Heat spreading effectiveness of a basic thermal design using graphite and air (left) compared to a thermal design using graphite and GORE Thermal Insulation (right). The basic thermal design fails to reduce hot spots because, while the heat is conducted through graphite in the xy-direction, it is also conducted in the z-direction of graphite, resulting in a hot spot. Using GORE Thermal Insulation instead of an air gap reduces z-axis conductivity, increases the spreading ratio and reduces hot spots.

Performance and Design Benefits

Improve Your Existing Solution With GORE Thermal Insulation: No More Compromises

Thanks to GORE Thermal Insulation, you can improve your existing thermal design without compromise.

Increase Performance with GORE Thermal Insulation Reduce Hotspot Temperature with GORE Thermal Insulation Thinner Product Design with GORE Thermal Insulation
  • With a kz lower than air, thinner GORE Thermal Insulation can replace the air gap, allowing for more graphite to be included
  • Delay throttling of performance by moving heat away from the heat source and blocking heat from the device surface
  • Enable components to operate at higher power for longer time
  • Reduce surface temperatures by 1– 6 °C (depending upon system power and insulation thickness)
  • Enable thinner designs while maintaining performance by replacing an air gap with Gore's thinner, compressible thermal insulation

PROPERTIES OF THERMAL INSULATION

GORE Thermal Insulation contains aerogel particles suspended in a PTFE matrix to deliver conductivity lower than that of air. This thermal insulation material for electronics can be used to reduce hot spots by replacing air gaps. It can also be paired with graphite to enhance thermal spreading in-plane without increasing thermal transfer through-plane.

GORE Thermal Insulation is a compressible thermal insulation. With compression levels up to 13% under a 100 kPa load, it can be used for tolerance take-up or to assist with impact resistance. It also has the ability to adhere to curved or stepped surfaces without negatively affecting performance.

GORE Thermal Insulation is a thermal and electrical insulator. With thermal conductivity lower than that of air, this insulation is also an effective electrical insulator, with a volume resistivity > 10^15 ohm-cm.

The typical thermal conductivity of electrical insulators is low, in the range of 0.03-0.8 W/m·K. However, GORE Thermal Insulation is far better, with conductivity as low as 0.020 W/m·K, while also delivering good electrical insulation.
