Gap fillers, also known as thermal gap pads, are a specialized type of thermal management material that are used to fill the gaps between two surfaces in electronic devices. These gaps can occur due to variations in the surfaces of the two components, or due to manufacturing tolerances. Without gap fillers, these gaps can lead to poor thermal performance, resulting in higher temperatures and decreased reliability of the electronic device.
One of the key properties of gap fillers is their ability to provide excellent thermal conductivity. This allows heat to be efficiently transferred from one surface to the other, reducing the temperature difference between the two surfaces. This is particularly important in high-performance electronic devices, where high temperatures can lead to component failure and decreased reliability.
Another important property of gap fillers is their ability to conform to irregular surfaces. This allows them to be used in a wide range of applications, from simple electronic devices to complex industrial systems. Gap fillers can be manufactured in a variety of shapes and sizes, making them a versatile solution for thermal management.
In addition to their excellent thermal conductivity and conformability, gap fillers also provide excellent electrical insulation. This is essential in electronic devices where electrical conductivity can lead to short-circuits and component failure. Our gap fillers are made of silicone, which is a dielectric material and it will not conduct electricity.
Gap fillers are important in electric vehicles (EVs) for a few reasons:
Thermal Management: Gap fillers provide excellent thermal conductivity, which allows heat to be efficiently transferred from one surface to the other, reducing the temperature difference between the two surfaces. This is particularly important in EVs, where high temperatures can lead to component failure and decreased reliability of the battery and other electronic components.
Battery Protection: Gap fillers can be used to protect the battery in an EV from the elements and to ensure a secure and reliable connection between the battery and the vehicle. This is achieved through the use of high-quality materials and precision manufacturing techniques. The result is a gap filler that maintains a consistent and reliable electrical connection, even in the most demanding applications.
Weight reduction: EVs have a lot of electronic components, and each component needs a thermal solution. By using gap fillers as a thermal solution, weight can be reduced as they are lightweight materials, and it helps to reduce the overall weight of the vehicle, which leads to increased energy efficiency and range.
Cost-effective: Gap fillers are cost-effective solutions for thermal management in EVs. They are manufactured in a variety of shapes and sizes, making them a versatile solution for thermal management. This also helps to reduce the overall cost of the thermal management system in EVs.
Noise reduction: The gap fillers also play an important role in reducing the noise coming from the EV. They absorb and dampen the noise, which makes the EV more comfortable for the passengers.
What We Use
We offer a wide variety of thermal materials, in particular ThermaCool®.
The ThermaCool line up is a family of high performance thermally conductive gap fillers that provide solutions to difficult thermal management problems.
These materials are used to fill gaps between two surfaces in electronic devices. They improve thermal performance by efficiently transferring heat from one surface to the other, reducing temperature differences between the two surfaces. They are also conformable, meaning they can adapt to irregular surfaces and can be used in a wide range of applications. Additionally, they provide excellent electrical insulation properties, which is essential in electronic devices to prevent short-circuits. They are typically made of silicone which is a dielectric material. Thermacool gap fillers make for the perfect solution for a wide range of uses.
