Does a power supply use convection or forced air cooling?
Traditional medium or high-rated power supplies use free-air convection or require forced air cooling to dissipate heat effectively, both of which have their own benefits and drawbacks. Convection cooling relies on natural-moving free air, but often results in the supply being derated in power since it is not an efficient way to dissipate heat.
What is a conduction cooled power supply?
Systems engineers and power supply specifiers are requesting more and more fanless power supplies. Conduction-cooled power supplies offer an alternative that incorporates the benefits of both cooling methods. How Do They Work?
Do Puls power supplies use convection cooling?
Some power devices with heat sinks depend on convection cooling (with or without forced air) to assist in transferring the heat away from the power devices to the cooler air. PULS standard din rail power supplies are convection cooled. Did you enjoy this great article?
Does a power supply need a 'cold plate'?
The supply requires a ‘cold plate’, or temperature-controlled mounting surface with certain thermal characteristics in order to dissipate heat efficiently. Specifications for mounting are given in the power supply datasheet. Figure 1: Graphic showing effective cooling methods in a U-bracket/enclosed power supply. Why Consider Conduction-Cooled?
Are conduction cooled power supplies better than forced air?
Conduction-cooled power supplies offer the design reliability of free air convection, and do not require the use of forced air to achieve their full potential. They produce equivalent, if not better efficiency levels than their forced air counterpart.
Are power devices rated for natural convection cooling?
Many power devices are rated for natural convection cooling as long as the air surrounding the unit remains within a limited temperature range that is cooler than the device. The advantage of this method of cooling is that no electromechanical fans are required.
