Inefficient ventilation: what are the consequences?

Inefficient ventilation is one of the first causes of electrical panel malfunction and should not be underestimated if you want to extend the health of the devices installed in. What happens when there are problems with ventilation?

The thermal dissipation

The heat produced inside by the activity of the electrical and electronic components, combined with the thermal dissipation capacity of an electrical panel, are decisive in the thermotechnical design phase of the cabinet and change according to the type of the latter and the environmental conditions. in which it is installed. Paying attention to these aspects allows to establish the necessary air flow and the best configuration for a correct and effective ventilation.

To better define these parameters, it is possible to rely on sizing software, such as the one available on our website, capable of evaluating the cooling power necessary to have the optimal temperature inside an electrical panel.

The consequences of inefficient ventilation

However, even when the panel is well dimensioned, malfunctions may occur in the filter fan, which compromise the ideal temperature conditions balance.

For example, a defect or obsolescence, deposits of dust or dirt… Operating conditions that limit the power of the fan, making it insufficient.

Inefficient operation of the fan inevitably leads to less air displacement, causing:

• high energy consumption
• rapid overheating
• a downgrading of the devices’ characteristics 
• a drastic reduction in the life of electronic components
• equipment failure
• interruptions of production lines and significant economic losses
• safety risks of people exposed to burns due to the excessive temperatures reached by the surfaces of the enclosure itself.

Preventing possible malfunctions and intervening promptly becomes essential. For this, Fandis offers a wide range of solutions for good ventilation inside the electrical panel and more complex systems for thermal management and performance monitoring.
