13、摘要摘要本設(shè)計說明書是關(guān)于PN2.5DN600浮頭式換熱器的設(shè)計，主要是進(jìn)行了換熱器的工藝計算、換熱器的結(jié)構(gòu)和強(qiáng)度設(shè)計。設(shè)計的前半部分是工藝計算部分，主要是根據(jù)給定的設(shè)計條件估算換熱面積，從而進(jìn)行換熱器的選型，校核傳熱系數(shù)，計算出實(shí)際的換熱面積，最后進(jìn)行壓力降和壁溫的計算。設(shè)計的后半部分則是關(guān)于結(jié)構(gòu)和強(qiáng)度的設(shè)計，主要是根據(jù)已經(jīng)選定的換熱器型式進(jìn)行設(shè)備內(nèi)各零部件（如接管、折流板、定距管、鉤圈、管箱等）的設(shè)計，包括：材料的選擇、具體尺寸確定
