No matter what electrical components are used, heat will occur more or less during electrical operation, because these components will have resistance, and if there is resistance, heat will be generated when electricity is used. However, the temperature of components will rise after long-term use, and the rise of temperature will affect the normal use of components. In the same way, the distribution box also needs to consume electricity and generate heat. For a long time, the temperature will be too high, which will affect the operation and delay the normal operation schedule. Therefore, the heat dissipation problem of the distribution box has to be considered, and it can even be used for a long time.

What are the heat dissipation skills of the distribution box? How does it work? The following power distribution box manufacturers to introduce you about the power distribution box cooling skills

One is that we dissipate heat through the heat pipe. The heat pipe is a kind of element with strong heat conduction ability. Its working principle is that the transpiration and condensation of working fluid in the non-specific vacuum tube can conduct heat transfer. It has very strong heat conduction ability, excellent isothermal performance, and the heat transfer area on both sides of the cold and hot sides can be arbitrarily covered, and it can transfer heat in a long distance, and can also control the temperature characteristic. The heat exchanger composed of heat pipe has the advantages of high heat transfer efficiency, compact structure and small fluid resistance loss.

The other one is to heat the heat through the installation of frequency converter structure. Here, the main circuit is planned to be a relatively large unit, and it is placed in the back wall of the explosion-proof cavity. Then, through an excessive radiator, it is connected with IGBT module, rectifier module and other heating elements. The outer wall of the explosion-proof shell is welded with a trough radiator. The excessive radiator and the trough radiator are connected through the heat pipe connect. The heat generated in the inverter passes through the rear wall of the explosion-proof chamber, and the heat pipe radiator radiates out.
