So, as the title describes, I am trying to build an infrared heating element for my own heating panel. I want to use this heater to cure an epoxy at 350F that is about 5" away. I'm an EE so the wiring and such will be simple but the heating calculations are beyond my area of expertise. Here is my train of thought so far: 1. I want to use nickel-chromium resistance wire to make an element. - How do I calculate the amount of heat this wire will give off? - I am told that I need a watt density of 7 watts/in2 for my application. I want the heater panel to have a heating surface of 15"x15" so depending on the diameter and resistance of the wire i can pick the correct size amount of wire. - Can I use this wire bare? I know there are different types of heaters but I don't know if I've ever seen one with just bare wire as a heating element. - Most companies use either a glass or fiber glass face to cover the element (basically for protection purposes I'm told). Does this effect my heating capabilities? 2. What are my other options as far as creating a heating element go?
