Reducing Energy Consumption
and Improving Reliability by Controlling Heat

Heat solutions tailored to each situation:from appliances,
to automobiles, to industry.

From everyday home appliances and mobile phones to electric cars and industrial machinery, one issue all electronics share is, "What can be done about heat?" The heat generated from electricity flowing through electronic circuits can cause the circuits and components to degrade. Blocking the heat generated and releasing it appropriately is essential to the creation of safe and durable products.

Panasonic has developed heat solutions for refrigerators, water boilers, and many other home appliances whose main purpose is to keep things hot or cool: highly insulating products such as the high-efficiency vacuum-based "Vacua Series" insulators. In addition to that, Panasonic also provides super-high-efficiency flexible "NASBIS*" insulation and highly thermal-conductive PGS graphite sheet as heat solutions.

Thin, Light, and Flexible : NASBIS High-performance Insulation

Heat generated inside electronic components and circuitry has a major effect on the functioning and reliability of products. Products cannot function properly above a certain temperature. In order to guard against heat in products as they become smaller, lighter, and more compact, Panasonic needed to create a new type of insulation which was thinner and lighter than ever.

For that, they developed NASBIS, a flexible insulation. It utilizes the technology Panasonic developed for manufacturing aerogel, as well as the super-insulating nanoporous medium* called silica aerogel. Because it can be contained in the gaps between fibers of non-woven materials, Panasonic succeeded in developing a unique process to manufacture it into uniform sheets, allowing for its mass production.

While only 50 microns (μm) thick, the thinnest in the industry, NASBIS achieves a thermal conductivity ratio of 0.02W/mK, the lowest ever without vacuum technology. Compared to foam insulations on the market, NASBIS is resistant to loss of thermal conductivity due to compaction, as well as degradation over time due to moisture absorption and heat. As an insulator, it's stable and highly effective.

Adding PGS Graphite Sheet for Finer Heat Control

By combining NASBIS with highly thermal-conductive PGS Graphite Sheet, heat control can be made even safer and more efficient. For example, by adhering PGS Graphite Sheet to the CPU of a smartphone (where its heat comes from) and NASBIS to the rear-side of its case, it is possible to prevent the front of the phone from becoming a hot spot, allowing for efficient heat exhaust. Panasonic's unique heat solutions can improve the comfort, portability, and battery management essential for small devices like smartphones.

Other Applications: Home Appliances and Automobiles

Smartphones and other portable devices aren't the only products with electronic circuits - they're also used in every electronic home appliance. Panasonic's myriad solutions support home appliances like air conditioners and microwaves that can be finely controlled as necessary, navigation systems that provide a safe and comfortable drive, and digital cameras that beautifully preserve memories. All of these devices, with their digitalization, sophistication, and miniaturization, require various countermeasures against heat. Panasonic will continue to use its unique heat solutions to provide heat countermeasures wherever they are needed.
