Mistaken One,
The thinner the better: Some customers in the selection of heaters blindly require thin, and as a sign to judge the strength of manufacturers.
In fact, the thickness of only 0.5 of the heater can also be done without requiring power and service life, but the process is only a little more complex.
Myth Two,
Judging by color: Some heaters in Europe and the US have grayish green surfaces, as well as some domestic heating rings with high brightness.
In fact, these are surface treatment of the relationship or even cut corners less of the tempering process.
Myth Three,
The softer the better: Soft heater surface armored metals are generally made of a special type of copper, in addition to which all processes are the same as those of other armored heaters.
This kind of copper every time from the quantitative foreign requirements are very large, and the market aggregate demand for soft heaters is not small so the general manufacturers do not want to produce.
Myth Four,
The greater the power, the better: The resistance of the electrothermal wire of the electric heater is selected according to the set power, and the greater the power, the smaller the total resistance. The resistivity of the electrothermal wire has an appropriate range, if the resistivity is too large, it needs a short or long, very fine or very thick electric wire, so that the size of the power of the electric heater has the difficulty of manufacturing and using. An important parameter of Electrothermal wire is surface power. The resistivity is too large, after entering a certain current, the surface power is also large.
Therefore, small power of electrical appliances, the use of small diameter small current, but the size of the current depends on the size of the resistance, the length and diameter of the electric wire is calculated. If blindly pursue high power, is to increase the surface area, to ensure that the surface power will not exceed the standard. At the same time in order to ensure high power, but also must have a large enough current, so in a certain surface area of the situation power has a limit! The quality of ultra-power electric heater is not guaranteed.
