DC fan operation principle: According to Ampere's right-hand rule, a conductor passes through a current, and a magnetic field will be generated around it. If the conductor is placed in another fixed magnetic field, suction or repulsion will be generated, causing the object to move. Inside the fan blade of the DC fan, a rubber magnet pre-filled with magnetism is attached. Surrounding the silicon steel sheet, two sets of coils are wound around the shaft.
The fan is an indispensable part of the air-cooled radiator, which plays an important role in the heat dissipation effect, and also has a decisive influence on the working noise of the radiator. The responsibilities of the fan in the air-cooled radiator are: relying on its own diversion effect, the air passes through the surface of the heat sink at a certain acceleration and in a certain way, and the heat exchange between the air and the surface of the heat sink is used to take away the accumulation on the heat sink. heat, so as to achieve "forced convection" heat dissipation. 1. Parameters
The principle of heat pipe: The heat pipe is filled with a special liquid heat transfer medium. When there is a temperature difference between the two ends of the heat pipe, the liquid at the evaporating end will quickly vaporize, bringing the heat to the condensing end. The greater the temperature difference between the two ends, the greater the evaporation rate. This heat conduction method can prevent the heat from accumulating in the heat-generating part, but evenly dissipate it to each aluminum fin of the heat sink, which greatly improves the heat conduction performance of the heat sink. Heat pipe heat dissipation mainly includes the following six interrelated
