Kyocera Corporation, Japan, introduced a new Peltier (thermoelectric) module with improved heat absorption. This new Peltier module has a maximum heat absorption rate 21% higher than Kyocera’s conventional products, enabling dramatically enhanced cooling performance.<\/p>\n
Kyocera’s Peltier modules are primarily used for temperature control of automotive batteries and seats, and this improvement in cooling performance will contribute to battery longevity. As of June 2024, they have shipped a total of 32 million units for automotive applications, and will continue to supply components that support the growth of the automotive industry.<\/p>\n
Maximum Heat Absorption (Qcmax) refers to the amount of heat absorbed by the Peltier module when operated at maximum current. It is defined as the temperature difference between both ends of the thermoelectric semiconductor being 0\u00b0C.<\/p>\n
A Peltier module is an energy conversion device with semiconductor elements sandwiched between copper substrates. When electricity passes through, one side of the substrate absorbs heat (cooling), while the other side releases heat (heating). This allows for rapid changes in surface temperature between heating and cooling, as well as the ability to adjust or maintain a specific temperature.<\/p>\n
Features of Kyocera’s Peltier module:<\/p>\n
1. High Heat Absorption
\nKyocera’s Peltier modules stand out due to their unique element technology (single crystal growth technology), which enables high heat absorption. Advances in this technology enable the maximum heat absorption capacity to rise 21% compared to Kyocera’s conventional products. The new Peltier module can absorb heat more efficiently, thereby enhancing cooling performance.<\/p>\n
2. High Responsiveness
\nFaster heating and cooling, in combination with a copper plate that provides high thermal conductivity, allow more rapid temperature-control response.<\/p>\n
3. High Reliability
\nKyocera prioritizes the reliability of its Peltier modules. They coat the element sides with resin to protect them from corrosion due to condensation. The entire process, from development to manufacturing and shipping, is handled in its facilities based in Japan, guaranteeing the highest quality control standards that instill confidence in its customers.<\/p>\n
4. Customizable
\nThe Peltier module is highly customizable with temperature-sensing thermistors and\/or heat dissipation fins. It can also accommodate size adjustments to match a customer’s application and casing requirements, providing a versatile solution for a wide range of automotive and other temperature control needs.<\/p>\n
