At the "Robot and Aerospace Festival Fukushima 2024" (November 29-30, Big Palette Fukushima), we will be exhibiting the "Thermal Property Measurement Device" and "Linear Actuator."

Introducing devices for measuring the thermal diffusivity of sheet-like and plate-like materials, as well as thermal evaluation devices for fiber orientation distribution!

Introducing Bethel's thermal property measurement devices. The "Thermo Wave Analyzer TA33/35" is a measurement device for the thermal diffusivity of sheet and plate materials, capable of measuring the thermal diffusivity of functional materials. The "Thermal Microscope TM" has been commercialized through joint development with the National Institute of Advanced Industrial Science and Technology's Measurement Standards Division, allowing for measurements in micro-regions and thin films. Additionally, we offer the "Thermal Imaging Scope TSI," which visualizes thermal conduction paths using infrared cameras and lasers, as well as the "Fiber Orientation Evaluation System TEFOD." 【Features of the Thermo Wave Analyzer TA33/35】 ■ High freedom of sample shape ■ Dynamic range from organic films to diamonds ■ Anisotropy evaluation through measurements in horizontal and vertical directions ■ Evaluation of defects and irregularities through distribution measurements *For more details, please refer to the PDF document or feel free to contact us.

Thermal conductivity can be measured non-contact! No surface treatment is required for carbon-based materials!

Yttria-stabilized zirconia is "an oxide based on zirconia, with the addition of yttrium oxide, which stabilizes the crystal structure of zirconia at room temperature." Applications include refractory materials, electrically conductive ceramics, materials for solid oxide fuel cell (SOFC) products, and due to its hardness and optical properties in single crystals, it is also used as a gemstone, such as cubic zirconia. In the case of fuel cell materials, thermal properties are important because the operating temperatures are high. Additionally, cubic zirconia closely resembles diamond and is often used as a diamond substitute. Like diamonds, it has a high refractive index, which gives it a sparkling appearance. The main difference lies in thermal conductivity. There are devices that can simply assess thermal properties to distinguish between diamond and zirconia. It seems that it is also used in thermal barrier coatings (TBC) for gas turbines. The measured result for thermal diffusivity was 1.13×10^-6 m^2s^-1. This value is 2 to 3 orders of magnitude lower compared to diamond. Our ThermoWave Analyzer TA allows for non-contact measurements. Many carbon-based materials can be measured without the need for surface treatment.

• Other physicochemical equipment

Leave the measurement of the thermal conductivity of carbon fiber reinforced plastic (CFRP) to us.

Carbon fiber reinforced plastics (CFRP), used in electric vehicles, aircraft, satellites, and rockets, require precise knowledge of thermal conductivity. For instance, when used in electric vehicles, understanding thermal conductivity is essential for heating performance and battery thermal management. Changes in electricity consumption due to heating performance and thermal management significantly affect driving range. Similarly, when used in satellites and rockets in the harsh environment of space, it is necessary to understand thermal conductivity to ensure heat resistance performance. With Bethel, you can accurately measure the thermal conductivity of this carbon fiber reinforced plastic (CFRP).

• Thermo-fluid analysis

Even thin and small samples, as well as samples with high thermal conductivity, can be measured!

We are also able to measure the thermal conductivity of conductive diamonds. Normally, diamonds are insulators, but by doping with boron, they can be made conductive, allowing for the creation of high-performance electrodes. This enables redox reactions that are impossible with electrodes made from other materials due to a wide potential window, and they can be used in harsh environments such as strong acids and strong alkalis, offering significant advantages. Personally, I am particularly interested in their potential use in the recycling of CFRP. The measurements will be conducted using the ThermoWave Analyzer TA35. [About the Samples] The samples this time have thicknesses of 30μm and 300μm, and with a sample size of 10mm x 10mm, it can be said that measurement with ordinary thermal conductivity measurement devices is nearly impossible. Measurement is only possible with the ThermoWave Analyzer. The 30μm thick sample is matte black with a smooth surface. The 300μm thick sample is also matte black, but its surface was slightly rough. However, this level of roughness has no effect on the measurements at all.

• Thermo-fluid analysis

Thermal conductivity distribution measurement and the anisotropy of thermal diffusivity in each part can be evaluated.

Here is an example of evaluating thin polyimide sheets. Polyimide sheets are resin materials primarily used as insulating substrates and insulating layers in electronic circuits. This time, we measured the thermal diffusivity in the thickness direction using a ThermoWave Analyzer TA on a sheet with a thickness of 7.5 μm. Even with the same polyimide sheet, there are significant thermal differences depending on the thickness. When comparing examples of 25 μm and 7.5 μm using the measure of thermal diffusion time, there is nearly a tenfold difference. The thinner sheet diffuses heat in one-tenth the time. For in-plane measurements, it is relatively easy to achieve time resolution since the distance between the heating point and the detection point can be established. However, for thickness direction measurements, it is necessary to detect rapid temperature changes, which affects the basic performance of the equipment. Traditional measurement methods make the measurement itself difficult. Additionally, at a thickness of 7.5 μm, the thermal effects of surface blackening treatment cannot be ignored, so we have devised methods to minimize these effects during sample preparation and measurement. The measurement results are as follows: Thermal diffusivity in the thickness direction: 0.103 × 10^-6 m²s^-1. This value is approximately 30% lower compared to the 25 μm thick polyimide.

• Other physicochemical equipment

Thermal conductivity distribution measurement and the anisotropy of thermal diffusivity in each part can be evaluated.

In recent years, the miniaturization and high output of electronic devices have rapidly advanced, and as a result, thermal management (heat dissipation) has become a very important issue. Traditionally, heat dissipation has been maintained by using metals, but in recent years, it has begun to be replaced by "high thermal conductivity resins." High thermal conductivity resins are "lightweight" and have "moldability" compared to traditional metals, are "corrosion-resistant," and above all, have the advantage of being "low-cost." However, there is also the disadvantage of low thermal conductivity, and many material manufacturers are actively developing solutions to address this issue. It is expected that "high thermal conductivity resins" will become mainstream in the future. On the thermal properties blog, we introduce examples of thermal conductivity measurements of "high thermal conductivity resins." http://blog.thermal-measurement.info/archives/cat_50051425.html

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
