PTC Ceramic Corrugated Heating Element, Corrugated PTC Heater Chip, Air PTC Heating Module｜Rare Earth Doped Barium Titanate Ceramic + Corrugated Aluminum Alloy Fin Double Insulated Material, 12V-380V
Our corrugated PTC ceramic heating assembly adopts barium titanate ceramic doped with rare earth as core heating medium, paired with corrugated aluminum alloy fin structure manufactured via high-temperature hydraulic lamination. This structured heater integrates heating, heat dissipation and overheat protection into one module. We support customized voltage, power, overall dimension and installation structure for bulk orders. Widely applied in civilian heating appliances and industrial hot air equipment, the product features stable heating performance and long operational lifespan, which can lower clients' after-sales maintenance cost evidently.
- Self-constant temperature operation without extra temperature control parts; no open flame during working process to eliminate fire risk
- Corrugated fin enlarges heat exchange area greatly, realizing rapid temperature rise and high thermal efficiency
- Built-in double insulation layer improves electric insulation performance, avoiding electric leakage safely
- Resistance attenuation is extremely minor under long-term continuous operation, stable heating output for years
We adopt high-temperature ceramic sintering, low-resistance silver paste electrode printing, hydraulic fin lamination, epoxy encapsulation insulation four core processes. Ceramic chips are sintered under precise temperature curve to guarantee consistent resistance; silver paste electrodes reduce contact thermal resistance; hydraulic pressing ensures tight bonding between fins and ceramic chips for efficient heat conduction; epoxy potting strengthens insulation and moisture resistance. Strict in-line testing is conducted after each production procedure to reject defective goods timely.
PTC ceramic material has positive temperature coefficient of resistance: when operating temperature rises to the Curie point, its resistance will surge sharply, automatically cutting down heating power. It will maintain balanced heat output by self-adjusting power without external thermostat. Excess heat will be dissipated through corrugated aluminum fins to surrounding air via convection, realizing stable ambient heating.
