What's the Cast Copper Heater 1？
The core definition of the Cast Copper Heater
The Cast Copper Heater is an electric heating device that uses an electric heating wire (resistance wire) as the heat source. It is embedded in a metal mold and is formed through a one-time casting process using pure copper or copper alloy under high temperature and high pressure.
The Working Principle of Cast Copper Heater
The Cast Copper Heater heats the electric heating wire through an electric current. The heat is conducted to the copper shell via magnesium oxide powder, and then is transferred to the heated object through heat conduction and radiation.
The main features of Cast Copper Heater
Due to the different physical and chemical properties of copper from those of aluminium, the characteristics of Cast Copper Heaters are also very distinct.
1. Exceptional heat conductivity: This is the core advantage of the Cast Copper Heater. The thermal conductivity of copper is much higher than that of aluminum. This means it has a faster heat response speed and an extremely uniform heat distribution, with almost no local overheating points.
2. Higher corrosion resistance: Compared to aluminum, copper has better corrosion resistance to many substances (especially water, steam, and some chemicals). This makes it perform better in humid environments than Cast Aluminum Heaters.
3. Better antibacterial properties: Copper ions have natural antibacterial and inhibitory properties, which makes it highly suitable for industries with extremely high hygiene requirements such as medicine, food, and drinking water.
4. Higher mechanical strength: The strength and hardness of copper are usually higher than those of aluminum alloys, making it more wear-resistant and more durable in dealing with some friction and pressure.
