2、力實(shí)驗(yàn)數(shù)據(jù)，設(shè)計(jì)了水冷散熱系統(tǒng)的循環(huán)泵。研究表明，優(yōu)化的吸熱盒模型流動(dòng)阻力明顯減小，換熱量明顯增加：設(shè)計(jì)的循環(huán)泵可滿足克服管路阻力的要求，且容量適配。關(guān)鍵詞：微型泵設(shè)計(jì)，CPU水冷，實(shí)驗(yàn)研究，數(shù)值模擬ABSTRACTOnthebaSisofsummarizationofdomesticarldforeignresearch姐d0VeralldeVelopmenttrendofthecoolingsystemofdeshopcompute
