Temperature controllable from -50 to 80℃ without cooling compressor and heating wire
Improved heating and cooling performance through the development of high-efficiency thermoelectric devices.

LG Innotek has mass-produced a 'thermoelectric module' capable of both cooling and heating.

Thermoelectric modules are electronic cooling/heating components that control temperature by supplying electricity to semiconductor elements. They utilize the Peltier effect, whereby when electricity flows through semiconductors with different properties, one side heats and the other cools.

LG Innotek's thermoelectric module is a semi-finished product with a heat sink and other components mounted on a 4 mm thick element. Without a cooling compressor or heating wire, the module temperature can be controlled from -50 to 80 degrees Celsius, depending on the ambient environment.

LG Innotek's thermoelectric modules eliminate the need for a cooling compressor, allowing for the production of smaller and lighter home appliances such as compact refrigerators and water purifiers.

Additionally, this product enhances driver convenience and driving safety. When applied to heating and cooling car seats, headlight dehumidifiers, and battery cooling devices, the temperature can be precisely and quickly controlled in units of 0.1 degrees using electronic control.

LG Innotek explained that the thermoelectric module is an eco-friendly component that does not use freon gas and does not have a heating coil, so it does not emit electromagnetic waves.

LG Innotek has developed a high-efficiency thermoelectric device, enhancing the performance of thermoelectric modules. The company announced that this technology increases heating and cooling capacity by 20% and reduces power consumption by 25% compared to conventional thermoelectric devices.

LG Innotek plans to begin mass production of small thermoelectric modules for heating and cooling, and expand their application to functional refrigerators and automobiles in the future.
