Heat dissipation principle of outdoor electrical distribution boxes
Electrical equipment that distributes power has a heat loss due to the impedance and/or resistance of its conductors. illustrates schematically the various types of power distribution equipment that an engineer will encounter during the design of a power system. As a window for air exchange inside and outside the electrical box, the heat dissipation hole's primary function is to allow hot air to be directly discharged from the outside of the electrical box. The following discussion applies to gasketed and unventilated enclosures. Higher temperature rises can be expected with unfinished aluminum and unfinished stainless steel enclosures due to. Chances are it started with an overheated component in a distribution box somewhere upstream. The formula is simple: Heat = I²R. Key design points include high-quality materials like ABS plastic, aluminum, and stainless steel that resist corrosion and UV.
