1. 散(san)熱(re)器(qi)組對方法
散熱器應(ying)選購合(he)格產(chan)品，上(shang)下對(dui)口(kou)表(biao)面應(ying)在(zai)一(yi)個平面上(shang)，不(bu)得(de)歪斜。對(dui)口(kou)中(zhong)心距離準確，對(dui)絲與散熱器內(nei)螺紋的(de)松緊應(ying)適(shi)度(du)(du)，間隙不(bu)可(ke)(ke)過(guo)大。墊(dian)(dian)(dian)(dian)(dian)片(pian)不(bu)得(de)使(shi)用(yong)橡(xiang)膠(jiao)(jiao)(jiao)墊(dian)(dian)(dian)(dian)(dian)或橡(xiang)膠(jiao)(jiao)(jiao)攙石棉(mian)(mian)的(de)合(he)成(cheng)墊(dian)(dian)(dian)(dian)(dian)，必須(xu)使(shi)用(yong)橡(xiang)膠(jiao)(jiao)(jiao)石棉(mian)(mian)墊(dian)(dian)(dian)(dian)(dian)（又(you)稱(cheng)石棉(mian)(mian)橡(xiang)膠(jiao)(jiao)(jiao)墊(dian)(dian)(dian)(dian)(dian)，它(ta)是用(yong)橡(xiang)膠(jiao)(jiao)(jiao)石棉(mian)(mian)板(ban)(ban)沖制(zhi)加工的(de)墊(dian)(dian)(dian)(dian)(dian)片(pian)），其厚度(du)(du)為1.0mm~1.5mm,不(bu)能用(yong)雙墊(dian)(dian)(dian)(dian)(dian)。橡(xiang)膠(jiao)(jiao)(jiao)石棉(mian)(mian)板(ban)(ban)的(de)牌號和規格見表(biao)2-25。表(biao)中(zhong)分高壓(ya)、中(zhong)壓(ya)、低(di)壓(ya)三種牌號，常用(yong)的(de)中(zhong)壓(ya)板(ban)(ban)和低(di)壓(ya)板(ban)(ban)沖制(zhi)的(de)墊(dian)(dian)(dian)(dian)(dian)片(pian)。中(zhong)壓(ya)墊(dian)(dian)(dian)(dian)(dian)片(pian)在(zai)使(shi)用(yong)前應(ying)在(zai)機(ji)油(you)(you)里(li)浸泡幾分鐘；低(di)壓(ya)板(ban)(ban)墊(dian)(dian)(dian)(dian)(dian)片(pian)應(ying)在(zai)機(ji)油(you)(you)里(li)蘸一(yi)下撈出來(lai)控(kong)干。使(shi)用(yong)時(shi)將墊(dian)(dian)(dian)(dian)(dian)片(pian)放入已調和（用(yong)清油(you)(you)調和）稀(xi)稠(chou)適(shi)度(du)(du)的(de)鉛油(you)(you)桶里(li)攪動，撈出來(lai)且不(bu)流淌(tang)，或輕度(du)(du)流淌(tang)即可(ke)(ke)使(shi)用(yong)。
組對(dui)(dui)時(shi)，應將散(san)熱器(qi)(qi)(qi)(qi)對(dui)(dui)口表面(mian)(mian)的(de)銹(xiu)污清(qing)除干凈，將正扣(kou)朝向(xiang)(xiang)上方，對(dui)(dui)絲(si)的(de)正扣(kou)朝向(xiang)(xiang)下方碼放(fang)好(hao)備用。把(ba)(ba)(ba)組對(dui)(dui)散(san)熱器(qi)(qi)(qi)(qi)的(de)架子(zi)與地面(mian)(mian)固定(ding)牢(lao)固。把(ba)(ba)(ba)正扣(kou)朝向(xiang)(xiang)上方的(de)散(san)熱器(qi)(qi)(qi)(qi)邊片(pian)(pian)固定(ding)在架子(zi)上，再把(ba)(ba)(ba)正扣(kou)朝向(xiang)(xiang)下方的(de)對(dui)(dui)絲(si)擰(ning)入散(san)熱器(qi)(qi)(qi)(qi)內1扣(kou)～2扣(kou)，然后(hou)把(ba)(ba)(ba)涂有鉛油的(de)墊片(pian)(pian)套在對(dui)(dui)絲(si)上。把(ba)(ba)(ba)第二片(pian)(pian)（中(zhong)片(pian)(pian)）的(de)正扣(kou)朝向(xiang)(xiang)上方摞在對(dui)(dui)絲(si)上用散(san)熱器(qi)(qi)(qi)(qi)鑰匙(chi)把(ba)(ba)(ba)已擰(ning)入第一(yi)片(pian)(pian)的(de)對(dui)(dui)絲(si)逆時(shi)針旋轉(zhuan)(zhuan)一(yi)扣(kou)再順時(shi)針兩(liang)(liang)人（兩(liang)(liang)個對(dui)(dui)絲(si)）同時(shi)輕輕旋轉(zhuan)(zhuan)，待兩(liang)(liang)個對(dui)(dui)絲(si)均人扣(kou)時(shi)，再快速擰(ning)緊即可。
特(te)別提醒：柱(zhu)形散(san)熱器14片(pian)(pian)(pian)以(yi)內用2片(pian)(pian)(pian)帶(dai)足(zu)（邊(bian)）片(pian)(pian)(pian)，15片(pian)(pian)(pian)～24片(pian)(pian)(pian)用3片(pian)(pian)(pian)帶(dai)足(zu)片(pian)(pian)(pian)。20片(pian)(pian)(pian)（含）以(yi)上應加裝4根附加拉(la)條，拉(la)條直(zhi)徑(jing)為ф10mm或ф8mm,散(san)熱器與螺母之(zhi)間應加裝鑄鐵騎(qi)碼（由散(san)熱器廠家提供）。
需要安裝冷風(feng)門(men)時(shi)(shi)，應把與支管連接(jie)的異側邊片在組對前(qian)鉆(zhan)孔(kong)(kong)。當系(xi)統為(wei)熱水(shui)時(shi)(shi)，應在邊片最上(shang)方某一角(jiao)處有(you)專為(wei)冷風(feng)門(men)鉆(zhan)孔(kong)(kong)用(yong)的加厚部位（其(qi)中心有(you)凹進表面的小(xiao)陷(xian)窩），以便(bian)鉆(zhan)孔(kong)(kong)。如(ru)該系(xi)統為(wei)低(di)壓蒸(zheng)汽(qi)采用(yong)時(shi)(shi)，則應在邊片下部下偏1/3處亦有(you)小(xiao)陷(xian)窩可供鉆(zhan)孔(kong)(kong)和攻(gong)絲。
鉆(zhan)孔(kong)所(suo)用鉆(zhan)頭(tou)直徑為ф8.6mm或ф8.7mm.
2. 散熱(re)器安裝(zhuang)
在這里，散(san)熱器(qi)安裝(zhuang)是(shi)指鑄(zhu)鐵柱型帶(dai)足散(san)熱器(qi)安裝(zhuang)。安裝(zhuang)前要將(jiang)已撼的燈叉彎（來回彎）裝(zhuang)到散(san)熱器(qi)上，如圖(tu)2-58所示。
圖2-59是鑄鐵柱型散熱器(qi)安裝，也適用于鋼柱型散熱器(qi)安裝。
圖(tu)2-60為散熱器鉤(gou)子制作(zuo)圖(tu)。
圖2-61 為(wei)散熱器卡(ka)子制作圖。
圖2-62為鑄鐵柱型散(san)熱(re)器托鉤位置及數量(liang)。
鑄鐵柱型(xing)散(san)執器安裝尺寸見表2-26。
圖2-63是在(zai)有保溫(wen)層(ceng)、空氣隔層(ceng)的(de)(de)(de)墻(qiang)上安裝(zhuang)散(san)熱(re)器托架（鉤(gou)(gou)）的(de)(de)(de)做法。圖2-63(a)和圖2-63(b)的(de)(de)(de)保溫(wen)層(ceng)、空氣隔層(ceng)的(de)(de)(de)總厚度用h表示。散(san)熱(re)器的(de)(de)(de)托鉤(gou)(gou)（架）固(gu)定(ding)在(zai)用14號槽鋼改(gai)制的(de)(de)(de)“過(guo)渡(du)件(jian)”上。如(ru)用于(yu)柱形(xing)散(san)熱(re)器的(de)(de)(de)固(gu)定(ding)卡等，在(zai)槽鋼的(de)(de)(de)腿上所需位置鉆ф6.7的(de)(de)(de)孔(kong)(kong)，進行M8普(pu)通螺紋攻絲；如(ru)果是柱形(xing)散(san)熱(re)器托鉤(gou)(gou)，可鉆?16孔(kong)(kong)將?16托鉤(gou)(gou)插入孔(kong)(kong)內(nei)焊(han)牢(lao)（見圖2-63)。
圖2-63(c)是(shi)在(zai)(zai)加氣混凝土或空心磚(zhuan)墻(qiang)上(shang)安裝散熱器(qi)托(tuo)鉤(gou)做法。在(zai)(zai)所需標(biao)高(gao)、位置用機磚(zhuan)砌：長度(du)＝360mm、高(gao)度(du)＝240mm、厚(hou)度(du)同(tong)墻(qiang)厚(hou)度(du)。托(tuo)鉤(gou)上(shang)下均(jun)應有不(bu)(bu)少(shao)于(yu)一層整(zheng)磚(zhuan)；托(tuo)鉤(gou)左右方向凈距均(jun)不(bu)(bu)小(xiao)于(yu)120mm。
由于樓層高(gao)度(du)和地(di)面抹灰厚度(du)的偏(pian)差而影(ying)響(xiang)立管(guan)甩口(kou)高(gao)度(du)時(shi)，只能采取鋸或墊(dian)散(san)(san)熱器的足來(lai)解決。圖2-64是墊(dian)的方法，圖2-64(a)的做(zuo)(zuo)法是因為散(san)(san)熱器與(yu)地(di)面的間(jian)隙(xi)小，而采用青鉛(qian)；圖2-64(b)的做(zuo)(zuo)法是因為間(jian)隙(xi)較大時(shi)的做(zuo)(zuo)法。如果墊(dian)的再高(gao)些時(shi)，則應點(dian)焊在散(san)(san)熱器足上。
