PTC heater: intelligent constant temperature heating technology
- ReleaseTime: 2024-12-17
PTC heater, also known as Positive Temperature Coefficient heater, is a device that utilizes the characteristics of PTC material to achieve heating. The following is a detailed introduction about PTC heaters:
1. Working principle:
PTC heaters use positive temperature coefficient materials (such as ceramics) as heating elements. When the temperature rises, the resistance of PTC material increases, which automatically limits the current and temperature, and has self-regulation function to ensure the stable and safe operation of the heater. The characteristic of PTC material enables PTC heaters to automatically reduce power output after reaching a certain temperature, achieving a constant temperature effect.
2. Main features:
-Self regulating: PTC heaters can automatically adjust power output according to changes in ambient temperature, preventing overheating without the need for additional temperature control devices.
-Safe and stable: PTC materials have strong high temperature resistance and can maintain a constant temperature at a set temperature, making them safe and reliable.
-Long lifespan and no noise: Due to the absence of mechanical wear or arc generation, PTC heaters do not produce noise and have a long service life.
-Rapid heating: PTC materials have excellent thermal conductivity, which can quickly reach the working temperature and improve heating efficiency.
3. Application areas:
PTC heaters are widely used, including electric vehicles, air conditioners, dryers, dryers, etc. In the field of new energy vehicles, PTC heaters are an important component of vehicle thermal management, used to provide warm air and constant temperature control. In addition, PTC heaters are widely used in household appliances and industrial equipment, such as air conditioners, hot air curtains, dehumidifiers, dryers, dryers, warm air blowers, bath heaters, etc.
4. Structural composition:
PTC heaters typically consist of galvanized outer pressure plates, stainless steel corrugated spring plates, galvanized inner pressure plates, single-layer aluminum heat sinks, PTC heating elements, double-layer aluminum heat sinks, nickel plated copper electrode terminals, and PPS high-temperature plastic electrode sheaths.
5. Market prospects:
With the gradual release of downstream demand, the development space of PTC electric heater industry will further expand. It is expected that in the coming period, enterprises with the production capacity of PTC electric heaters for new energy vehicles will occupy a larger market space.
In summary, PTC heaters have been widely used in multiple fields due to their high efficiency, safety, and energy-saving characteristics, and have broad market prospects.
