Regardless of the use of electrical components, heat will be generated to some extent during electrical operations. As these components have resistance, electricity will generate heat. However, long-term use of components will increase the temperature, which will affect their normal use. Similarly, distribution boxes also require power consumption and generate heat, which can lead to prolonged high temperatures affecting operations and delaying normal work schedules; So the heat dissipation problem of the distribution box has to be considered, as it can even be used for a long time if it is extended.

What are the cooling skills for distribution boxes? What is the effect? Below, the distribution box manufacturer will introduce us to the heat dissipation skills of the distribution box

One way is through the use of heat pipes for heat dissipation. Heat pipes are components with strong thermal conductivity, and their working principle is to transfer heat through the evaporation and condensation of working fluids in non vacuum tubes. They have excellent characteristics such as strong thermal conductivity, good isotherm, the ability to cover the heat transfer area on both sides of the cold and hot sides at will, and the ability to transfer heat at long intervals, as well as the ability to control temperature. A heat exchanger composed of heat pipes has advantages such as high heat transfer efficiency, compact structure, and low fluid resistance loss.

Another method is to use the layout of the frequency converter structure to dissipate heat. Here, the main circuit is designed as a relatively large unit and placed on the back wall of the explosion-proof chamber. Then, it is connected to the IGBT module, rectifier module and other heating elements through a heat sink for transition. The outer wall of the explosion-proof shell is welded with a groove shaped heat sink, and the transition heat sink is connected to the groove shaped heat sink through a heat pipe. The heat generated inside the frequency converter is emitted through the heat pipe groove shaped radiator on the back wall of the explosion-proof chamber.
