Enhanced Cooling with Peltier Module

The Peltier modules manufactured by Kyocera have become essential components for the temperature control of automotive batteries and seats, playing a crucial role in improving cooling performance and ultimately contributing to the longevity of batteries. With a significant milestone reached in June 2024, Kyocera proudly announced the shipment of a total of 32 million units specifically designed for automotive applications.

One of the key distinguishing features of Kyocera's Peltier modules lies in their utilization of unique element technology, known as single crystal growth technology. This innovative approach enables these modules to achieve high heat absorption capabilities. Recent advancements in this technology have resulted in a remarkable 21% increase in the maximum heat absorption capacity compared to Kyocera's previous products, allowing for more efficient heat absorption and enhanced cooling performance.

Not only do these modules excel in heat absorption, but they also demonstrate exceptional responsiveness, facilitating faster heating and cooling processes. This is made possible through the incorporation of a copper plate with high thermal conductivity, which significantly enhances the speed and efficiency of temperature control responses.

To ensure the durability and longevity of the Peltier modules, Kyocera has taken proactive measures by coating the element sides with resin. This protective layer safeguards the modules from corrosion caused by condensation, thereby enhancing their reliability. Additionally, Kyocera maintains stringent quality control standards throughout the entire production process, from development to manufacturing and shipping, conducted at their facilities in Japan.

Furthermore, Kyocera offers a high degree of customization for their Peltier modules, allowing for the integration of temperature-sensing thermistors and heat dissipation fins based on specific requirements. The company also provides flexibility in adjusting the size of the modules to align with the unique application and casing needs of customers, offering a versatile solution for a wide range of automotive and other temperature control applications.

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°C.
