If you ever tried to figure out how heaters are functioning? Heaters, the lifesavers that keep us all warm on those chilly days! So, today we are going to discuss about special type of heater named finned tube. So this heater is also an amazing invention used almost everywhere to keep both the human and machine warmer. In this article, we will cover the following topics: finned cartridge heater definition & working principle, advantages, types of finned cartridge heaters, tips for choosing a finned cartridge heater and some safety precautions to consider.
A finned cartridge heater is a type of heating element that can offer a source of heat in a wide variety of applications. It is a stainless steel if you are looking for something strong and durable strength heater. Imagine a tube, or an elongated cylinder. There are two parts to a finned cartridge heater: the heating element and a covering sheath, typically called a sheath.
The heating element consists of a special wire that heats up when the electricity passes through. This wire is wound about a part known as a ceramic core, which serves as an insulator to retain the heat. From there, everything is wrapped in a huge shell made of stainless steel. Steel fins on the heater are used to enhance its surface area and therefore, makes it more efficient in heat transfer.
So, how does it work? This heating element heats up extremely quickly when electricity flows through it. This heat is then passed to the covering sheath and also to the fins. The fins then warm the air surrounding the heater or a surface being heated. This incremental makes the thermo couple efficient for temperate adding.
Finned cartridge heaters, like all other kinds of heaters you might think about using them for, are available in various types. They are specifically designed for different uses and applications. Below are some of the common types of finned cartridge heaters you may come across:
Low Watt Density Heaters: The watt density with these heaters is low as opposed to high-density heater, so they are termed low-watt density heaters. They're best suited for projects that require uniform heating, which indicates even heat distribution.
If the heater is to be used in high-temperature environments, the sheath material should be a corresponding one. Think about things like whether the material will work with the chemicals you are using and how tough it needs to be to survive its environment.
