Information

   Speaking of cooling system, a lot of people think that the fan and heatsink. In fact, they ignore the one and unremarkable, but it plays an important role in the vehicle - a heat transfer medium. Computer CPU is typical of the need for good cooling of power devices, thus we say that it is a thermally conductive material. Want to talk about, to express their experiences of various types of thermal power devices and views.
Why do I need a heat transfer medium

    Some may think that the bottom surface of the CPU or the heat sink is very smooth, no heat transfer medium between them. This view is wrong! Due to impossible to make a flat surface machining idealized, so there is a lot of ravines or gap between the CPU and heat sink, which is air. We know that a high thermal resistance of air, so you must use other substances to reduce the thermal resistance, otherwise the performance of the radiator will be greatly reduced, if not impossible to play a role. So heat transfer medium came into being, its role is to fill the gap between large and small processor and heat sink, increasing the contact area between the heat source and heat sink. Thus, the heat conduction effect is a heat medium, to increase the effective contact area between the CPU and the heat sink is its most important role.
