Power dissipation is the reason your devices get hot when you are using them. Every component has a resistance, as you know, and when in use, they contribute to the heat emitted by your phone or computer. The CPU, in particular, is densely packed with transistors, is a great source of heat, and is also a critical component to cool down.

So, let''s assume my current power supply is 80% efficient, and my rig draws 350w, pulling ~440w from the wall. Let''s also assume this is a constant load, all day every day. Does this mean that 90w is lost as heat? Now, let''s assume I replace it with a unit that is 90% efficient. This means the...
Device operation often produces heat generation G (depicted here by the conventional symbol for an electrical resistor which generates heat when a current flows through it). The heat generation will cause the temperature of the volume to increase. Heat flux J H from the volume will occur in a direction from higher temperature to lower.

Cooling systems that use a liquid that changes phase — such as water boiling on a surface — can play an important part in many developing technologies, including advanced microchips and concentrated solar-power systems. But understanding exactly how such systems work, and what kinds of surfaces maximize the transfer of heat, has remained a …
The design of a cooling system is critical in power converters based on wide-bandgap (WBG) semiconductors. The use of gallium nitride enhancement-mode high-electron-mobility transistors (GaN e-HEMTs) is particularly challenging due to their small size and high power capability. In this paper, we model, study and compare the different …
