Overview

Meet Growing Thermal Challenges in Mobile Devices Using GORE® Thermal Insulation
GORE Thermal Insulation x DELL XPS 13
DELL uses GORE Thermal Insulation to improve performance and slim the design of its laptops.

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 the designer’s ability to direct heat by greater control of z-axis thermal conductivity. More 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
Shown above is how 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 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. With a thermal conductivity through-plane (kz) significantly lower than 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 greater control of z-axis thermal conductivity. More control means superior spreading options and design flexibility. Combining GORE Thermal Insulation with graphite for example – one of many possible configurations – allows for more graphite to be included due to needing a thinner amount of insulation compared to an air gap to get the same heat reduction.

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 in the xy-direction, it is also conducted in the z-direction resulting in a hot spot. Whereas utilizing GORE Thermal Insulation instead of an air gap reduces z-axis conductivity, increasing the spreading ratio and reducing hot spots.

Performance and Design Benefits

Increase Performance with 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 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 thinner insulation
