A mistake,
The thinner the better: Some customers when selecting a heater persistently ask thin, as judge manufacturer is a sign of strength. In fact in the case of does not require the power and the service life of the thickness of only 0.5 heater also can do, just process more complicated.
Erroneous zone 2,
Judge: by color
Europe and the United States of some of the surface of the heater in sage green, and some of the domestic production of fever circle high brightness. Actually these are all surface treatment of the tempering process is even less to cut corners.
Myth 3,
As soft as possible:
Soft surface of the heater armoured metal generally use a special kind of made of copper, in addition to all the process with other armored heater work is the same. This kind of copper each quantitative foreign demand is very big, and the soft heater total market demand is not so general factory production.
Myth,
The greater the power, the better:
The resistance is set according to the power of the electric heater heating wire to choose, the greater the power, the less the total resistance. Resistivity of electric wire have a proper range, if the resistivity had greater than small, requires a short or long, thin, or very thick heating wire, so to size power electric heater has the difficulty of manufacture and use. An important parameter of the heating wire, power is surface. Resistivity is too large, into a certain current, surface power is large. So small power electrical appliances, to choose small diameter small current, but the size of the current is determined by the size of the resistance heating wire length and diameter is calculated.
If blindly pursue high power, is to increase the surface area, ensure that the surface power not overweight. At the same time to ensure high power, and must have enough big current, so under the condition of the surface area of a certain power has a limit! Super power electric heater quality cannot be guaranteed.
