Of course, the situation "24V DC Cooling Fan" time than the more complex, the need to analyze and calculate calculated by simulation software. In an ordinary digital circuit design, we seldom take into account the heat of the integrated circuit, because low-power chip is generally small, natural heat under normal conditions, the temperature of the chip will not be much. With the continuous improvement of the chip rate, the single "24V DC Cooling Fan" chip's power consumption has gradually become larger, for example: Intel Pentium CPU power can reach 25W. When the heat of natural conditions can not make the chip temperature control requirements under the index, you need to use the appropriate measures to accelerate cooling "24V DC Cooling Fan" chip surface heat release, the chip working at normal temperature range inside.
