Fan cooled battery chargers

There are many factors that determine the type of charger required for a particular application. Choosing the right charger is critical to ensure that all requirements are met and that the charger is not over specified. One of the primary factors in charger selection is the operating environment. Please review our waterproof page to determine what is appropriate for your application. If it is determined that a waterproof product is not required, then fan cooling can provide several advantages. The pros and cons of fan cooling or forced air cooling are described below.

Advantages

Reduced component temperatures translate into higher reliability and lower MTBF

Fans are very effective in forcing air through the unit and reducing internal temperatures

Power output is 2-3 times greater than convection cooling

Most restrictions on the system thermal design are eliminated

The charger can be mounted in any orientation

The physical size of the charger can be significantly reduced

Disadvantages

Acoustic fan noise can be a negative for quiet environments

Dust and other contaminants can be drawn into the unit

Accumulation of contaminants on the fan and components reduces cooling effectiveness

Air filters mitigate the negative effects but require maintenance to clear or change

Fans are usually the least reliable component in the unit
