Effect of temperature on the power distribution cabinet

In life or work, we will contact all kinds of electrical appliances, such as air conditioning, TV, all know that it is impossible to expose to the sun outside the sun, the temperature is too high of course not good, so the power distribution cabinet, temperature has an impact on the use of power distribution cabinet?

First of all, the temperature will certainly affect the operation of the power distribution cabinet, whether it is high temperature or low temperature.I believe we all know, the distribution cabinet has indoor use, but also in outdoor use.High temperature phenomenon, is a lot of equipment will have the situation, and when we design the power distribution cabinet, we have taken into account its heat dissipation problem.
Of course, when in use, we also need to pay attention to it, so how to prevent it from appearing high temperature phenomenon!
Some components inside the power distribution cabinet are under use conditions, and their normal working conditions are specified: the upper limit of the ambient air temperature does not exceed 40℃; the average of the ambient air temperature 24 degrees Celsius does not exceed 35℃; the lower limit of the ambient air temperature is not lower than-25℃.
In the summer high temperature season of time, the temperature in the box of the power distribution cabinet will rise to a very high level. If the temperature at this time greatly exceeds the ambient temperature stipulated by the power distribution cabinet, it will cause the electrical components in the box of the power distribution cabinet to overheating and fail.
So when the redesign, we design the shutter, add the cooling fan, can discharge the high temperature in the power distribution cabinet.
Overheat, and the failure occurs.
