The summary of tubular electric heating element and function

Electric heat pipe and heat pipe, heat pipe, scientific name tubular electric heating element, it is in the metal tube into the roll of linear heat wire ( Resistance wire) , electric heat pipe and its surroundings and fill in the gaps with good heat resistance, thermal conductivity and insulation insulation powder ( MgO） At both ends, heat wire department has lead to good or pick out lead. It has simple structure, high mechanical strength, high thermal efficiency, safe and reliable, easy installation, long service life, etc. Is widely used in all kinds of saltpeter tank, water tank, oil tank, acid and alkali trough, the fusible metal melting furnace, air heating furnace, drying oven, drying oven, hot pressing molding device, etc. Electric heat pipe is specially converts electrical energy into heat energy of electrical components, due to its cheap, easy to use, easy installation, no pollution, is widely used in all kinds of heating. Functional features small size, large power: primary heater adopted cluster type tubular electric heating element. Hot echo fast and high accuracy of temperature control, high thermal efficiency. High heating temperature: heater design * high temperature can reach 850 ℃. Average outlet temperature of the medium and high temperature control precision. Using wide limits, and strong adaptability, the heater can be used in explosion-proof or popular place, explosion-proof grade of d Ⅱ class B and class C, pressure of 20 mpa. Long service life, high reliable sex: the heater adopts special electric materials manufacturing, low power load design appearance, and adopting multiple maintenance, makes peace electric heater and life drastically. Can the initiative in moderation: according to the requirements through the heater circuit design, can be convenient to complete the export parameters such as temperature, flow, pressure active control, also can connect with computer. Energy saving result, electricity happened almost 100% of heat to the heating medium. Structure unit power electric heat pipe heating area tube surface area per unit power: pipe diameter load values ( Wcm square) φ 6 ~φ; 10 ≤ φ22 10. 1 ~φ; 14 ≤ 20φ 14. 1 ~φ; 18 ≤ 16个φ 18. 1 ~φ; 22 ≤ 12个φ 22. 1 ~φ; 40 ≤ More than 10 surface load refers to cooperate with metal mould heating, water heating can be multiplied by 2 ~ 2. 5. Air heating is 50% ~ 60%. The main parameters of electric heating tube: 1. Power supply voltage, V. 2. The power frequency, Hz; 3. Rated voltage, V. 4. Rated power, kw; 5. Working temperature, ℃; 6. Outside diameter, Single end electric heat pipe die aperture) mm; 7. Spread length, mm; 8. Overall dimensions, mm; 9. Weight, kg.
