Tube Core Heat Sink Thermal Performance Parameters Optimized

The performance optimization of thermo dynamic characteristics of tube-core-finradiator is presented in this paper.A theoretical analysis and research is done on radiator body and an optimumcalculation about radiator's performance parameters is made in given conditions. Basedon the analysis of heat transfer and flow about radiating unit, the experiential referenceequations of heat transfer coefficient, water resistance and air resistance is obtained.This paper places emphasis on the performance optimization of thermo dynamiccharacteristics of tube-core-fin radiator and analyses five parameters such as water inlettemperature, water outlet temperature, air outlet temperature, water flow velocity and airinlet velocity. A mathematical model is established considering interaction and restrictionof these five parameters and for the purpose of getting optimum relationship between thelose of heat transfer and the lose of water pump. An iterative optimum calculation ismade on some primary parameters which have influences on thermo dynamiccharacteristics of tube-core-fin radiator. Some satisfying results are obtained throughapplying the optimum calculation software which is based on the basic program language:Visual Basic 6.An analysis and comparison between calculation results and experimental results isdone in which the experiment is conducted according to national standard. It is shownthat the mathematical model and restriction conditions are reasonable, the method isfeasible and calculation results are credible. In the end, some optimum equations areobtained which have some reference value for the development, design, manufacture,measuring and maintaining of tube-core-fin radiator.
