In dusty locations, electrical equipment must be fully enclosed, and natural ventilation is not suggested since dirt and dust can interfere with its performance. In these cases, outdoor industrial cabinet airconditioning solves high-temperature problems inside electrical enclosures, extending component life and lowering the danger of component failure due to overheating.
In some cases, the space available in the rack server for electrical panels is limited. Electrically powered coal and ore reclaiming equipment, mining equipment, earth moving equipment, and ships are a few examples. This equipment is frequently powered by a medium voltage trailing wire or overhead pantograph and makes heavy use of variable speed drives.
Damage Due To Heat Load
The heat load of an electrical inclosure is the amount of heat produced in that cabinet, which is commonly given in Watts. Heat can be generated by a variety of sources, including:
- Electrical equipment: Power supplies, servo drives, motor drives, and transformers have efficiency ratings ranging from 85 to 95 per cent. Between 5 and 15 per cent of the energy lost is turned to heat.
- Solar load: Solar radiation considerably increases the heat load in outdoor enclosures.
- Ambient heat: Enclosures in hot environments absorb heat from their surroundings.
High Temperatures in Electrical Enclosures Can Be Dangerous
- The danger posed by overheated electrical components in panels cannot be overstated. Many electronics are unable to survive temperatures exceeding 140 °F, and electrical enclosures may reach these temperatures in severe settings with significant ambient heat loads and inadequate ventilation.
Conclusion:
Extend the life of your application's electrical components by contacting specialists today to select an air conditioner that is appropriate for your inclosure and application.
