Unlike desktop computers, smartphones do not need an internal fan for cooling. Instead, their architecture is designed to be more power efficient and not generate as much waste heat. In fact, the typical smartphone runs for 10 hours with just a little battery power. In addition, smartphones are also made to conserve energy. So why do smartphones not need an internal fan? Let’s take a look at the pros and cons of this design feature.
Why do not smartphones need an internal fan like a computer? One common reason is that cell phones use thermal transmission sheets to protect the circuitry. Thermal transmission sheets are made from materials like carbon and copper, which have exceptional solid diffusion properties. This material appears as a single sheet but is actually made up of many thin, conductive layers of carbon crystal membrane. These layers are connected at different levels, which allows heat to quickly diffuse.
Another factor to consider is the size of the processors. Desktop PCs require large components that are inexpensive to produce and engineer. They also have more slots for new parts. And while smartphone processors are relatively powerful, they are not as powerful as desktop PC processors. Furthermore, phone processors don’t get particularly hot when held. That is a good thing for the environment, but it’s not always possible to avoid the heat from the processor.
