Miniature Thermoelectric Cooler Industry Analysis and Outlook
Wednesday,08 Jan,2025
A Miniature Thermoelectric Cooler (TEC) is a device that utilizes the Peltier effect for thermoelectric conversion.The device is used for localized cooling or heating applications by creating a temperature difference between the two ends through the flow of electric current. Miniature Thermoelectric Coolers are used in many small devices that require precise temperature control due to their small size, fast response, and high reliability.
Type:
Single-stage TECs: for smaller temperature differences, commonly used in consumer electronics or small laboratory equipment.
Multi-stage TECs: Achieve larger temperature differences by stacking multiple layers of Peltier elements for applications requiring low temperatures.
Customized TECs: Customized for specific application needs, such as special dimensions, packaging or performance requirements.
Applications:
Optoelectronics: e.g. temperature control of laser diodes to ensure stable performance.
Medical devices: for maintaining specific temperatures for biological samples or drugs.
Portable electronics: e.g. portable coolers, temperature controlled cell phone cases.
Scientific research: including cooling of miniature thermocouples and sensors.
The global thermoelectric cooling market is growing, benefiting from the demand for miniaturized and high-efficiency devices. According to market analysis, the thermoelectric cooling market is expected to reach USD 850 million by 2023, with miniature thermoelectric coolers accounting for a certain percentage.
The U.S. leads in the development of thermoelectric cooling technologies, especially for high-performance applications. micro TECs introduced by companies such as Laird Thermal Systems are widely used in optoelectronics, medical, and defense applications. According to a report by the National Science Foundation, the U.S. R&D investment in thermoelectric materials and devices increased by 10% in 2023.
The demand for miniature thermoelectric coolers is growing rapidly in China, especially in the telecom equipment, consumer electronics, and emerging medical device markets. According to the study, China's production and exports of thermoelectric cooling equipment have grown significantly in 2023, partly due to the improvement in technology and production efficiency by domestic companies.
