Analyse du le refroidissement effet de électrique brasage fer série connecté avec diodes
For ordinary diodes, depending on the model, the forward voltage drop of ordinary rectifier diodes is general around {{0}}.7V, while the forward voltage drop of Schottky diodes is even lower. If the solder iron is powered by power frequency AC power, the series diode can have a voltage reduction effect, because the AC power is rectified by the diode half wave, and le effectif tension valeur est réduit de moitié. Cependant, 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 significative reduce the temperature, the only way is by significantly reducing 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 requires some circuit experience and foundation. Another method is to use a finished DC adjustable step-down module, which changes the output voltage through a variable resistor. Et il peut être modifié à automatiquement refroidir down, et détection composants can être ajouté à le soudure fer cadre. Après le soudage fer est placé, le voltage can être automatiquement abaissé.
So, using a series diode to cool down is not ideal for the final effect due to the small amplitude of the reduced voltage.
