220V Cooling Fan common thermal resistance

"220V Cooling Fan" common radiator flat radiators, radiator and inter digital profiles radiator. Also due to the heat sink finger inter digital of the question, "chimney effect" in favor of thermal convection, so the same resistance, inter digital radiator volume is smaller than the other radiators, light weight. Domestic radiator inter digital model SRZ series. Domestic profiles "220V Cooling Fan" radiator model XC series, DXC series, XSF series. Table 10-3 and Table 10-4, respectively, for the domestic profiles radiator and domestic radiator inter digital models and corresponding thermal resistance tables. Air-cooled thermal design principles and calculation in many applications, even the installation of the radiator, there is no guarantee under the power system operates in the temperature requirements. If in this case, "220V Cooling Fan" power of the working conditions (such as electrical conditions, the surrounding fluid temperature, ambient temperature of a closed wall, shell temperature and place orientation, etc.) are also not very good improvement, then only Select a forced convection cooling.
