Ring-Shaped Aluminum Heating Element Specifications (Core Parameters)

Product Characteristics (Core Features)

• ​​Uniform Circular Heating​​: The ring-shaped design enables 360° omnidirectional heat conduction, eliminating localized hotspots. Ideal for applications requiring uniform heating, such as electric kettles (even boiling), soy milk makers (consistent bean cooking), and electric pots (even pan heating).
• ​​High Efficiency & Energy Savings​​: Combines an aluminum alloy housing (thermal conductivity ≥200 W/(m·K)) with a nickel-chromium alloy core (thermal conductivity ≥11 W/(m·K)) to achieve a thermal efficiency of ≥92%, reducing heating time (e.g., boiling 1.5L of water in 3-5 minutes).
• ​​Multi-Device Compatibility​​: Customizable ring diameter (100-400mm) and width (20-80mm) fit mainstream small appliances, including electric kettles (bottom ring slots), coffee machines (extraction chamber heating rings), electric pots (base heating rings), and bottle warmers (encircling rings for pots).
• ​​Corrosion & Scale Resistance​​: The aluminum alloy housing is treated with anodization or coated with a ceramic layer to resist water/steam corrosion. The smooth surface reduces limescale adhesion by 50% compared to standard aluminum components, extending maintenance intervals.
• ​​Safe & Reliable Operation​​: The nickel-chromium alloy core is encapsulated for insulation, and the housing features a grounded design to prevent electric leakage. An optional temperature sensor interface supports ±5℃ precise temperature control (e.g., 40-60℃ constant temperature for bottle warmers, 90-105℃ extraction for coffee machines).
• ​​Lightweight Design​​: Aluminum alloy has a low density (2.7g/cm³), making the overall weight 30%-40% lighter than stainless steel heating elements. Ideal for weight-sensitive devices like electric kettles and portable coffee machines.
• ​​Long Lifespan Stability​​: Optimized thermal expansion coefficient matching (aluminum alloy and nickel-chromium alloy have similar coefficients) reduces thermal stress fatigue. Maintains stable performance for over 8000 hours under high-frequency use (e.g., 2 hours daily operation).
