These three methods are usually analyzed and described separately. However, heat removal is always a combination of these methods. Conduction is very important in electronic equipment and is the only mode of heat transfer occurring in solids. Conduction is transmission of heat by transfer of kinetic energy from one molecule to another and it can occur in a solid, liquid, or gas. In liquids, conduction and convection can occur simultaneously, while all three modes of heat transfer occur simultaneously in a gaseous environment.
Radiation is the sole mode of heat transfer in a vacuum.
Martek Power Abbott's power supplies are designed so that cooling is accomplished primarily by conduction through a solid heat sink and then by convection into the surrounding environment. Therefore, the power supply must be heat sunk at the baseplate. Two such firms are Aavid and Thermalloy . Their websites may contain more detailed information and other related products. Inc.
