Convection cooled power resistors
from few watts till 100kW.
Convection-cooled resistors are available in ratings of up to 100 kW and use natural convection for cooling. Natural convection occurs when there is no external source of airflow, such as a fan. Self-cooled resistors are suited to applications where other cooling methods are not available or are difficult to provision.
The performance of convection-cooled resistors can be improved with forced-air cooled. Fans or blowers can increase airflow through the resistor to help achieve greater power handling capacity. The natural air-cooled resistor is ideal for pulse load applications with short cycles and high power levels, like energy dump and charging or discharging applications.
