Types of Heating Elements
Date:2014-07-22 12:38:26
- There are lots of different kinds of heating elements. Sometimes the nichrome is used bare, as it is; other times it's embedded in a ceramic material to make it more robust and durable (ceramics are great at coping with high temperatures and don't mind lots of heating and cooling). The size and shape of a heating element is largely governed by the dimensions of the appliance it has to fit inside and the area over which it needs to produce heat. Hair curling tongs have short, coiled elements because they need top roduce heat over a thin tube around which hair can be wrapped. Electric radiators have long bar elements because they need to throw heat out across the wide area of a room. Electric stoves have coiled heating elements just the right size to heat cooking pots and pans (often stove elements are covered bymetal, glass, or ceramic plates so they're easier to clean). In some appliances, the heating elements are very visible: in an electric toaster, it's easy to spot the ribbons of nichrome built into the toaster walls because they glow red hot. Electric radiators (like the one in our top photo) make heat with glowing red bars(essentially just coiled, wire heating elements that throw out heat by radiation), while electric convector heaters generally have concentric, circular heating elements positioned in front of electric fans (so they transport heat more quickly by convection). Some appliances have visible elements that work atlower temperatures and don't glow; electric kettles, which never need too perate above the boiling point of water (100°C or 212°F), are a good example. Other appliances have their heating elements completely concealed, usually for safety reasons. Electric showers and haircurling tongs have concealed elements so there's (hopefully) no risk of electrocution.
