Control temperature as required

Peltier module (thermoelectric module) is a thermal control module that has both "warming" and "cooling" effects. By passing an electric current through the module, it is possible to change the surface temperature and keep it at the target temperature.

BASIC STRUCTURE

Kyocera's Peltier module structure has two types of semiconductor elements arranged in tandem sandwiched between copper substrates. When electricity is passed through the module, electrons move in one element and positive holes move in the other element, this is called the "Peltier effect." This allows one side of the substrate to absorb heat and the other to radiate heat, so the hot and cold sides to be switched depending on the current direction. It can also be used as a thermoelectric power generation module using the "Seebeck effect" in which a current flows by applying a temperature difference on both sides of the Peltier module.

BASIC PERFORMANCE

Features of Kyocera's Peltier modules include unique columnar shape elements and copper substrates.

We succeeded in alleviating stress concentration and improving long-term durability by using the columnar shape elements. Also, corrosion resistance due to moisture condensation is improved by coating the outer element of the surface, allowing us to achieve the reliability required to operate in harsh automotive environments. In addition, the copper substrate has low thermal capacity and uniform heat distribution, which contributes to quick response and small temperature variation.

    Battery temperature management

    Kyocera's Peltier modules are used for battery temperature management, and can improve battery life and help reduce battery size. Kyocera's modules can withstand the severe demands required for automotive applications.

  • Mobility

    Mobility Seat temperature control

    Seat temperature control

    By redirecting the cool air generated by the Peltier module using a fan, the seat can be cooled faster than the whole cabin air conditioner. In addition, the temperature of the driver's seat and the passenger's seat can be controlled individually. Kyocera’s Peltier module can also be supplied with a fan and radiation fin bonded directly to the substrate.
