Gali a serija diodai prijungti an elektrinis litavimas geležis pasiekti tikslas aušinimas išjungimas
The DC power supply directly supply power to the sliting iron, but without the addition of temperature detection and control circuits, the temperature cannot be kept constant and will vary with the welding area. If the temperature is too low, it may cause slow tin melting speed, while if the temperature is too high, it may cause the solder iron head to okside too quickly and prevent alavo from being taikoma. Idealus būdas to išspręsti the problem of constant temperature is to add temperature detection and control circuits. If a regular electric slitavimas geležis is naudotas for modifikacija, as the litavimas geležis pats daro ne turi a temperatūra aptikimas komponentas, it ne be keičiama to temperatūra kontrolė ir gali tik būti aušinama pagal mažinant slėgį.
For paprastieji diodai, priklausomai on the model, the forward voltage drop of ordinary rectifier diodes is paprastai around {{0}}}.7V, while the forward voltage drop of Schottky diodes is even lower. If the slitavimas geležis is powered by power frequency AC power, the series diode can have a voltage reduction effect, nes the AC power is rectified by the diode half wave, and the effective voltage value is reduced by half. Tačiau, for DC voltage, the ideal voltage drop of the diode is only 0.7V, and the amplitude of voltage reduction is too small, which has no significant effect on temperature reduction.
To žymiai sumažinti the temperature, the only way is by significantly reduce the voltage. There are two ways to reduce voltage. One is to change the reference voltage of the sampling part of the internal output terminal voltage of the charger, which need some circuit experience and foundation. Another method is to use a finished DC adjustable step-down module, changes the output voltage through a variable resistor. Ir it can be modified to automatically cool down, and detection components can be added to the slitavimas iron frame. After the slitavimas geležis is placed, the voltage can automatically lowered.
So, using a series diode to cool down is not ideal for the final effect due to the small amplititude of the reduced voltage.
