What Part Of The Structure Of The Heat Gun
Jul 24, 2018

If you want to use a heat gun, you must first understand the structure of the heat gun.

Nowadays, when welding or picking up some components, we often use the heat gun as a tool, mainly by heating the resistance wire of the heat gun, and then blowing hot air to work. If you want to use a heat gun, you must first understand the structure of the heat gun.

The main part of the heat gun is the circuit part, and the rest of the shell can be seen without introducing it. The structure of the control circuit of the heat gun has roughly five parts. The first part is the temperature signal amplifying circuit, which can sense the temperature when the heat gun is working. The second part is the comparison circuit. If there is no special requirement, we generally do not need to understand this part of the circuit. The third part is that the thyristor control circuit is mainly used to control the entire circuit of the heat gun. The fourth part is the sensor, which is used to sense the internal and external environment. The last part is the wind control circuit.

In practice, in order to facilitate the use, we will add some auxiliary circuits in the heat gun, so that the role of the heat gun is more complete. The auxiliary circuit mainly includes three parts: a temperature display circuit, a shutdown delay circuit and a zero-crossing detection circuit. With the auxiliary circuit, the operator can use the heat gun more conveniently.
