l optimization , product selection and development of new products play a guiding or supporting role, thereby avoiding routine test methods cycle length, and cost is high. The use of engineering software MATLAB optimization toolbox , not only algorithms and reliable, and without a lot of programming procedures , greatly reducing the putational workload, improve work efficiency, is an effective way of working. Can only improve the work efficiency, but also to avoid the waste of resources . 參考文獻(xiàn) [1]楊友麟,曾廣安 .我國(guó)化工節(jié)能潛力與對(duì)策 .大連 :全國(guó)第七屆熱力學(xué)分析 與節(jié)能學(xué)術(shù)報(bào)告會(huì)論文【 R].

Joint pipe machine generally 24 ~ 26m / s. Thermal Tape Cooling air disturbance opened to bring the louver like holes to destroy the flowing air to the heat adhesive layer on the belt surface , to improve heat dissipation . By the corrugated fins and cooling with alternating warp posed of welded pipe radiator with radiator . 主片及上下水室 散 熱器的主片及水室的構(gòu)造均以工藝簡(jiǎn)便,節(jié)約材料,易于釬焊和裝配,牢固可靠為前提。根據(jù)芯體中翅片排列方式分,汽車散熱器主要分為管帶式和管片式兩種 . Overview of Auto Radiator Auto Radiator belong recuperative heat exchanger , where heat pipes is generally oval tube or flat tubes, finned outer layers are arranged in order to strengthen the cold side of the heat transfer . Typically , car radiator from the main piece , core body, seals and other parts welded together by brazing process , it is pact, lightweight , thinwalled and heat transfer and high strength. According to the core body fin arrangement points, automotive radiator divided into tube and tube sheet with two kinds , 2 汽車散熱器結(jié)構(gòu)設(shè)計(jì) 散熱管 咬口焊接制造水
