What's the Cast Aluminum Heater 1？
The core definition of the Cast Aluminum Heater
The Cast Aluminum Heater is an electric heating device that uses an electric heating wire (resistance wire) as the heat source and embeds it into a metal mold. It is then formed through a one-time casting process using aluminum alloy under high temperature and high pressure.
You can think the structure of Cast Aluminum Heater as a "sandwich":
· Core: The heat-generating electric heating wire, responsible for generating heat.
· Shell/Insulator: The aluminum alloy tightly wraps around the electric heating wire, serving both as a protective cover and a heat transfer medium.
· Insulation Material: Between the electric heating wire and the aluminum shell, high-purity magnesium oxide powder is filled. It is an excellent insulator that prevents leakage of electricity and a good heat conductor that can efficiently transfer heat.
The main features of Cast Aluminum Heater
Due to its unique manufacturing process and materials, the cast aluminum heater possesses a series of outstanding advantages.
1. High thermal efficiency, excellent heat conduction performance: Aluminum alloy is an excellent heat-conducting material, which can quickly and uniformly transfer heat from the electric Heating Element to the surface of the heated object, reducing heat loss.
2. High mechanical strength, durable: The cast aluminum shell is very sturdy and can withstand certain impacts and pressures, and is unlikely to deform, with a long service life.
3. High working temperature: The maximum surface working temperature is usually up to 350°C ~ 450°C, which can meet the needs of most medium-high temperature heating scenarios.
4. Flexible shape, high adhesion: Using casting technology, various shapes such as flat plates, circles, and irregular shapes can be produced as needed, which can closely adhere to the surface of the heating equipment, improving heat conduction efficiency.
5. Good safety performance: The internal magnesium oxide powder still maintains good insulation performance at high temperatures, effectively preventing the short circuit between the electric heating element and the shell, with high safety.
