Relying on the unique thermal characteristics of positive temperature coefficient, PTC heaters are expanding from the field of traditional home appliances to multiple scenarios such as new energy vehicles, medical disinfection, and commercial water purification, and technological upgrades and demand expansion jointly promote the steady growth of the industry scale. In the household field, PTC heaters have been widely used in heaters, clothes dryers, smart water dispensers and other products, and their advantages of automatic current limiting and precise temperature control have effectively improved the safety and energy efficiency of home appliances.

Technological innovation has become the core driving force for PTC heaters to expand the boundaries of application. The mass production application of nanoscale ceramic-based PTC chips has increased the thermal conversion efficiency of the heating unit to more than 92%, and the service life has exceeded 8,000 hours; Under the trend of intelligent integration, PTC heaters equipped with IoT modules can realize remote temperature control, energy consumption monitoring and other functions, becoming the standard configuration in the high-end market. In the field of new energy vehicles, PTC heaters, as an important part of the battery thermal management system, can ensure the stability of the battery pack temperature in extremely cold environments, and the supporting demand continues to be released with the growth of new energy vehicles. In addition, emerging scenarios such as high-temperature sterilization equipment in the medical field and large-capacity instantaneous heating devices in the commercial field have also brought new growth space for PTC heaters.
