Ever worried about the heat on your inverter casing? Well, it’s not a cause for concern, but rather a sign that the system is functioning as designed: the casing serves as an integral part of the cooling mechanism.
Why heat sink matters for inverters
In the realm of electronics, active components generate heat when current flows through them. Each of these components has a designated operating temperature. When an inverter’s heat dissipation performance is sub-optimal, the temperature within the inverter may exceed the limit, potentially compromising component efficiency, lifespan, and overall operational reliability.
Furthermore, the heat generated during inverter operation causes power losses, thereby impacting energy conversion efficiency and overall power output.
Deye’s heat sink design
Presently, inverter heat dissipation techniques predominantly embrace natural convection and forced air cooling.
For low-power inverters, we have aluminum cooling fins, which maximize surface area for enhanced air contact and rapid heat dispersion. For higher-power ones, on the basis of more cooling fins, forced air cooling mechanisms featuring intelligent cooling fans are added, accelerating airflow to superior heat dissipation.
Inverter casing’s role in heat dissipation
Except for the heat sink, the inverter casing itself also shares a load of heat dissipation, fastening the heat transfer process. And when placed in specific environments, like during summer when external temperatures reach 40°C, the casing’s temperature typically ranges from 55°C to 60°C, accounting for the sensation of heat when touching the inverter casing.
In conclusion, rest assured of the mild heat you feel when touching an inverter’s casing. It is a sign of a well-functioning thermal management system, which safeguards your inverter’s components, ensuring they remain efficient and durable.
