C type aluminum heating tube

Product Applications

Household appliances: electric kettle, instant water dispenser, air fryer, health pot.

Product parameters and specifications

Power range:
Household: 500W–2000W (electric kettle, coffee machine, electric hot pot, milk warmer, soy milk maker, wall breaker)
Working voltage: 110V/220V single-phase AC or 380V three-phase AC (global power grid compatible, error ≤±5%).
Resistance value: 2Ω–50Ω (accurately matched by voltage and power, error ≤±3%).
Working temperature:
Conventional model: continuous and stable operation of 150°C–300°C (self-limiting temperature design, anti-overheating).
High temperature model: short-term tolerance of 400°C (customized anodized layer + ceramic coating required).
Material:
Base material: aluminum alloy (thermal conductivity ≥200W/m·K, lightweight design).
Surface treatment: anodized layer (thickness 15μm, corrosion resistant) or ceramic coating (high temperature resistant to 600°C).
​​Heating wire: nickel-chromium alloy (NiCr, high temperature oxidation resistance) or PTC ceramic chip (self-limiting temperature characteristics).
​​Dimensions:
​​C-type tube diameter: Φ10mm–Φ30mm, bending radius ≥50mm (adapt to curved mounting surface).
​​Length: 100mm–1500mm (supports U-shaped, spiral or special-shaped customization).
​​Service life: 20,000–80,000 hours (based on operating temperature and coating protection).
​​Customizable service: support power, voltage, bending angle adjustment, optional explosion-proof certification (Ex d IIB T4), IP protection level (such as IP68), integrated NTC sensor, etc.

Core advantages

​​Efficient heat dissipation and heat conduction:
​​The C-type bending structure optimizes the heat flow distribution through CFD, and the heat convection efficiency is increased by 40%, which is suitable for the forced air cooling scene of the curved surface.
The thermal conductivity of aluminum alloy is 5 times that of steel, and the volume is reduced by 60% at the same power, which is suitable for compact equipment.
​​Self-limiting temperature safety feature:
​​PTC ceramic chip or NiCr heating wire + temperature control module, automatically reduce power when the temperature exceeds the set value, no external thermostat is required, and overheating and combustion are prevented.
​​Quick response and energy saving:
Lightweight design (density 2.7g/cm³) + low heat capacity characteristics, heating to 200°C within 30 seconds, energy consumption is reduced by 30% compared with traditional heaters.
​​Corrosion resistance and long life:
The anodized layer is resistant to salt spray test ≥500 hours, and the ceramic coating is acid and alkali resistant (pH 1–14), and the life is extended by 2–3 times compared with ordinary aluminum.
