Normal design of the electric control cabinet, either in the electric control cabinet below the air inlet, the top or both sides of the upper part of the air outlet, relying on the natural convection of air to achieve heat dissipation, or in the lower part of the air inlet, both sides of the upper part of the forced exhaust fan to realize the flow of air to cool down.
If it is the first one, as long as the cabinet to keep the air inlet and outlet can be smooth; the latter one will have to check whether the exhaust fan is working properly.
Generally speaking, the temperature of the air in the space of the electronic control cabinet does not exceed 55 degrees will not be a problem.
