style="text-indent:25px">鋁擠式散熱片鋁材質(zhì)由于本身柔軟易加工的特點(diǎn)很早就應(yīng)用在散熱器市場，鋁擠技術(shù)簡單的說就是將鋁錠高溫加熱后，在高壓下讓鋁液流經(jīng)具有溝槽的擠型模具，作出散熱片初胚，然再對散熱片初胚進(jìn)行裁剪、剖溝等處理后就做成了我們常見到的散熱片。鋁擠散熱片的成本低，技術(shù)門檻要求也不高，不過由于受到本身材質(zhì)的限制散熱鰭片的厚度和長度之比不能超過1：18，所以在有限的空間內(nèi)很難提高散熱面積，故鋁擠散熱片散熱效果比較差，很難勝任現(xiàn)如今益攀升的高頻率CPU。</p><p> 就散熱片材質(zhì)來說，每種材料其導(dǎo)熱性能是不同的，按導(dǎo)熱性能從高到低排列，分別是銀，銅，鋁，鋼。不過如果用銀來作散熱片會太昂貴，故比較好的方案為采用銅質(zhì)。雖然鋁便宜得多，但顯然導(dǎo)熱性就不如銅好(大約只有銅的50%左右)。 </p> <p> 目前常用的散熱片材質(zhì)是銅和鋁合金，二者各有其優(yōu)缺點(diǎn)。銅的導(dǎo)熱性好，但價格較貴，加工難度較高，重量過大(很多純銅散熱器都超過了CPU對重量的限制)，熱容量較小，而且容易氧化。而純鋁太軟，不能直接使用，都是使用的鋁合金才能提供足夠的硬度，鋁合金的優(yōu)點(diǎn)是價格低廉，重量輕，但導(dǎo)熱性比銅就要差很多。有些散熱器就各取所長，在鋁合金散熱器底座上嵌入一片銅板。 </p> <p> 對于普通用戶而言，用鋁材散熱片已經(jīng)足以達(dá)到散熱需求了。 </p> <p> 北方冬季取暖的暖氣片也叫散熱片。 </p> <p> 散熱片在散熱器的構(gòu)成中占有重要的角色，除風(fēng)扇的主動散熱以外，評定一個散熱器的好壞，很大程度上取決于散熱片本身的吸熱能力和熱傳導(dǎo)能力。 </p> <p> <br /> </p> <p> <br /> 單模光纖的尺寸為9-10/125μm，并且較之多模光纖具有無限量帶寬和更低損耗的特性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="惠州通訊SFP定制,SFP"

1.鋁擠型散熱片這是普遍用于現(xiàn)代散熱中的優(yōu)良散熱材料,業(yè)界大部份都使用6063T5質(zhì)量鋁材,其純度可達(dá)到98%以上,其熱傳導(dǎo)能力強(qiáng)﹑密度小﹑價格便宜所以得到了各大廠商的青睞。 </p> <p> 2.鋁鑄造散熱片雖然鋁擠散熱片的價格低廉,制造成本也較低,但其由于受到鋁材本身質(zhì)地較軟所局限,他的鰭片厚度與鰭片的高度之比一般不會超過1:18,所以各PC生產(chǎn)廠商對于散熱面積不斷增大,而散熱空間不變。 </p> <p> 3.鋁切削散熱片雖然從散熱面積上解決了這種鋁擠型所不能達(dá)到的效果,但是現(xiàn)在模具的精密程度直接影響到我們散熱片整體的造型和散熱能力,所以更多的廠商開始想到用加工機(jī)械精密的刀具直接將成塊的鋁錠進(jìn)行切削到... </p> <p> 4.銅切削散熱片使用了這么長時間的鋁擠型散熱片,不管如何改變我們的加工工藝,都難以滿足不斷增長的CPU發(fā)熱量,有的廠商不得不在成本上不惜血本,舍鋁而求銅,由于銅的導(dǎo)熱系數(shù)遠(yuǎn)遠(yuǎn)大于鋁,熱傳導(dǎo)能力的成倍... </p> <p> 5.嵌銅散熱片這種折衷的方案解決得較為完美的應(yīng)屬AVC**的嵌銅技術(shù)。這是將銅熱傳導(dǎo)速度快,密度大,吸熱能力強(qiáng)的優(yōu)勢與傳統(tǒng)鋁擠型密度輕,價格便宜,方便量產(chǎn)的優(yōu)勢進(jìn)行了和諧的統(tǒng)一。 </p> <p> <br /> 單模光纖價格便宜，但單模設(shè)備較之同類的多模設(shè)備卻昂貴很多。東莞QSFP散熱器</p><p style="text-indent:25px">SFP光模塊從速率和光纖類型上可分為百兆單多模、千兆單多模4種?；葜萃ㄓ峉FP定制</p><p
