Fanless pc-Fanless PCs - Making Computers More Efficient

We have recentlyIndustrial monitor seen a massive increase in interestpanel PC in noiseless computers， and different low-noise technology equipments。 Noiseless technology has become an integral part of our business over the few years。 No longer you have to deal with the irritating sound of the computers though they are used everywheredigital signage today。

As a number of PC´s seemingly make a big quantity of noise once theyFanless pc are turned on。 The fixed disk makes the case shudder， the processor and power fan perpetually produce a buzzing sound。 Several users are irritated by their constantly buzzing machines， and request solutions to make them noiseless。 Thus for the customer´s comfort， several new system units， information projectors and printers are engineered and made as fanless to ensure asunlight readable noiseless operation。 Thetouch screen monitor need more Fanless PC has shot through the sky with everyone wanting such a computer。

With the increase in quality of theatreIndustrial pc PCs and， the customized fanless computer is growing in quality。 Fanless all in one PCs use a mix of sound moistening cases， robust passive cooling and correct flow of air to chill parts that may otherwise want loud， large fans to chillBox PC them。 Heat build up is the primary concern in a fanless computer as managing all the heat generation without the fans is a difficult task。

Making a laptop noiseless means you would like a fanless UPS， and low power CPU and no disk drive。 No fan impliesVideo wall that no air is being drawn through the case， cooling the inside area of the pc and no air is cooling the power supply itself。 You need a CPU that may be passively cooled with a heat sink or via heat pipes that transfer the heat generated to the pc caseIP66。

Get a computer processor that generates as little heat as possible。 Then you may be ready to cool the chip solely by employing a conductor。 You will then be ready to cool the processor with a slower running and quieter fan if it generates less heat。 This whole process makes the entire operation of computers seemingly noiseless freeing the users of constant annoyance。

Choose a 3D graphics card that does not require its own fan toAll in one computer stay cool， unless you are an extreme game player and want the quickest of the cards available。 Then your noiseless computer possibility is by employing a water cooling system。 This system is the best solution for cooling computers that requires high performance in overclocking situation。

Some motherboards currently have inbuilt support for temperature measure and fan motion off once it is not required。 A number of them even have inbuilt fan speed control as per their requirement， and these are to appear for when selecting a motherboard for a noiseless computer。 Closed fan heat sinks are usually regarded having higher cooling properties than the cheaper ones and these days most computer users frequently use heat sinks for cooling the heat generated by their computers。

Aluminum slide gslide bearingates are easy to customize in major styles like villa style， fortress & palace style， castle style， cottage style and so on。 For the construction of any style slide aluminum gates， metal work specialists consider the size， shape and other details indicated in the gate schedule thoroughly。

Aluminum gates and iron fences are of high importance in residential and commercial areas。 They are used to maintain privacy， enhance appearance and support complete safety of spaces。 Depending on the choices and budget of individuals， the gates can be selected as semi-private， private and different decorative styles。

The styles like double gate with top rail， double aluminum gate， fortress style， villa style， cottage style and palace style are more in demand。 All these styles vary in terms of designs， size and other specification aspects； therefore， professional metal work specialists always consider the construction details indicated in the gate schedule to deliver the desired products to clients。

Frame

The frame can be channel mount or flat back。 The frame is selected with great attention as it is considered as an integral component of structural shapes。 Another point to consider is the designing of holes and to assemble such holes properly to form the waterway openings。 The head channels being another useful concern are sufficiently spaced to support easy removal of the gate slide。 To avoid metal to metal contact between the frames and slide of gates， the experts use polymer guide liner。

Manual lifts

In the construction of aluminum gates， the next point to consider is to design the lifts as geared crank type or handwheel mentioned in the construction schedule。 The lifts are designed with having bronze lift nuts， thrust bearings and a bronze stop nut to control the downward movement of the slide。 Lifts are also made with the concern to make its grease lubrication simple when needed。

Stems & seals

About gate stem， the stem is designed with the property to withstand twicePlastic bearing the force exerted by a pull on the crank or handwheel。 To support the stem， experts use cast iron stem guides or angle guides and cast bronze guide collar to maintain the appropriate ratio of spaces。

Seals are also important for better functioning of iron fences or aluminum slide gates。 The seals are securely fastened and are designed with the features of easy to replace and adjust by the users。

The construction step of gate doesn´t end here。 It involves a lot more aspects to consider like the slide， flush bottom and motor operated lift with integral controls like a control power transformer， space heater， limit switches， open-closed push buttons etc。 With all these aspects， the gates are designed and constructed with extensive care and attention to help one find the perfect product to suit the needs。

powder metal-The Powder Coating Process

Although powder sintered metalcoating was become pregnant as a technique of finishing metal， innovation has actually evolved to make sure that it is now a common choice for ceramics， plastics and even timber。 Study shows that powder coating is the fastest expanding covering tool and with the ecological advantages coupled with its excellent finishing properties， it is a fad that is most likely to continue。 Sorts of grain coatingThere arepowder metal 2 primary sorts of powder coatings； thermosets and thermoplasticsWith thermosetting variations， as the powder cooks， it responds with chemicals in the particle polymer which boosts little weight； enhancing the efficiency residential properties。 Polycarbonate types do not alter especially nor have any added responses， it simply flows out into the final coating。

Powder coating processStage 1 - Pre therapy This concerns prepping the element or component， and as any sort of painting application， groundwork is all essential to accomplish the best possible appearance。 It is essential to eliminate oils and lubes and steel oxides and this is carried out typically by a range of chemical and mechanical procedures，sintered metal dependent likewise upon the dimension， product， and finish required。 The several period chemical pre-treatments typically entail using phosphates or chromates in submersion or by splashing。 From an environmental perspective those supplying phosphate preparations are my favored option as chromates can be dangerous to the environment。

Yet another approach of groundwork is sandblasting and shot-blasting， where blasting abrasives are utilized to offer surface structure and groundwork for glass， plastic or wood。 Silicone carbide is suitable for grinding metals and plastic media blasting usages plastic abrasives that are sensitive to substrates such as aluminium。 Stage2 - Thepowder metal particle applicationThe most used technique is electrostatic spraying through a spray gun。 The object is grounded and the gun divulges a positive electric powered cost onto the particle which is then sprayed and accelerated towards the element by the effective electrostatic fee。 The element is heated up， and the agent merges a systematic movie， and cooled down to develop a hard finish。 We at times heat up the metal initially and spray the particle onto the warm substrate。 Pre-heating can aid to attain a much more systematic surface but can easily also create various other complications， such as runs created by excess powder。

Agent may likewise be administered making use of specifically adjusted electrostatic discs。 An additional approach， known as the Fluidised Bed procedure， involves warming the substrate and then soaking it in to an aerated， powder-filled bed。 The powder sticks and thaws to the warm things， with further heating needed to complete healing the coating。 When the covering surpasses 300 micros， this technique is normally used。 Electrostatic Fluidised Bed Covering: Electrostatic fluidised bed application makes use of the same fluidising procedures as above but with considerably less grain depth in the bed。 Electrostatic charging happens in the bed to make sure that the particle becomes charged as the fluidising air lifts it up。 Charged grain bits develop a cloud of charged particle above the fluid bed。 When a grounded component is travelled through the charged cloud the particles will be attracted to its area。 The parts are not pre-heated。

減速機國內外狀況

國外在先進減速機的設計生産上已經十分成熟，一些知名生産商已經擁有一百余年的減速機生産經驗，市場份額也十分可觀。比如旗下FLENDER減速機是目前業內最大減速機供應商，在産品結構設計、制造方面具有很高的造詣。

國外減速機在電力、食品、建築、礦業、水利等諸多行業都有著廣泛的應用，其制造生産標准相比國內也更高，我國的硬齒面減速機標准也來源于的生産標准。國內減速機的發展曆史也有近40年，生産廠家數目衆多，形式也多樣，目前，國內各類通用減速器的標准系列已達數百個，基本可滿足各行業對通用減速器的需求。但是與國外相比我國減速機水平仍然有較大差距，同國外外減速器行業存在的比較突出的問題是，行業整體新産品開發能力弱、工藝創新及管理水平低。

隨著近幾年國內經濟的快速發展，重型機械行業出口量的增多，作爲一個重要基礎行業的減速器行業發展異常迅猛。減速器企業正向著産銷規模擴大，加工能力和技術水平持續提高發展。未來減速器市場行業前景將一片大好。

　　 重型機械市場需求量大

在重型機械市場需求量增加的同時，行業也在産品升級、兩化融合、節能減排方面開展了卓有成效的工作。在産品升級方面，多年不變的老産品技術更新步伐在加快。橋門式起重機行業企業采用聯合或者獨立研發的方式，紛紛對老産品進行革新，形成了行業産品升級的熱潮。北京起重運輸機械研究院聯合衆多企業開展了橋式起重機系列輕量化工作，目前取得了階段性進展。行業積極引入變頻調速傳動技術、遙控和信息化技術，加快産品向高端技術的升級。業界開發的起重機無齒輪箱變頻傳動主提升裝置開始在市場中試水。

國際市場對重型機械裝備和備件的需求還將增長。隨著歐美國家經濟的逐漸複蘇，重新確立實體經濟在國家經濟中的地位，以及發展中國家的基本建設需求，重型機械産品在國際市場上會有更大的發展空間。

重型機械中的齒輪減速機發展態勢看好

隨著國家對機械制造業的重視，重大裝備國産化進程的加快以及城市改造、場館建設等工程項目的開工，減速機市場前景看好，整個行業仍將保持快速發展態勢，尤其是齒輪減速機的增長將會大幅度提高，這與進口設備大多配套采用齒輪減速機有關。

減速機是一種動力傳鋼片聯軸器遞機構，使用它的目的是降低轉速，增加轉矩。它的種類繁多，型號各異，不同種類有不同的用途。重型機械用減速器設計的産品包括了各類齒輪減速器、行星齒輪減速器、蝸輪蝸杆減速器及擺線針輪減速器，也包括了各種專用傳動裝置。

目前工程上的驅動設備已經越來越多在使用電機驅免鍵式軸環動，由于電機的轉速較高扭矩較低一般無法直接驅動執行設備，這就必須使用減速機來傳遞動力。工程上常用的減速機就是齒輪減速機，齒輪減速機已經有很長的的應用曆史，現代工業的快速發展也對減速機提出了更高的要求，主要表現在要求更高的功率容量、更短的研發周期、轉矩範圍大、設計形式多樣、高壽命高可靠性等。本次設計的意義就在于結合現代工業要求以及目前的生産水平對傳統減速機進行優化，並且通過這次設計可以對自己已經學習的知識再次鞏固與綜合運用，鍛煉自己的設計計算能力，培養及提高自己對標准參數的查閱與選用、計算公式的運用、圖紙。

拉伸彈簧-彈簧鋼材深加工應用和性能優化探討

　　彈簧制造企業及材料加工企業主壓縮彈簧要完成從熱軋線及板材加工到成爲彈簧制造直接狀態的步驟，主要線材改制，如：退火冷拔、表面磨光和剝皮、線材處理等。許多鋼鐵企業也向後一體化發展，爲彈簧造企業直接提供所需的原材料。彈簧材料深度加工求及方法往往是根據彈簧制造者的需求決定。

　　目前，國內提供的彈簧材料主要執行標准爲B/T1222—2007《彈簧鋼》，交貨狀態主要爲熱軋狀，材料方式主要爲盤料，也有棒料。部分鋼鐵企業供冷拔盤料、銀亮鋼棒、韌化處理鋼絲、熱處理油淬火—回火）線材等。熱軋狀態的彈簧型材（線材、板材、帶材）對彈制造企業來說其特征是表面粗糙、缺陷深度大，通深度是線徑公差之半；表面脫碳層大，熱軋態。5—2。5%線徑，冷拔態1。0—2。0%線徑；線徑公差大，軋態（GB/T14981—20092014GB/T908—2008），冷態（GB/T3078—2008，GB/T905—2008）；硬度範圍

　　明確，“熱軋+熱處理”的技術規範其硬度是≤BW321，精確硬度需要供需雙方再協定；晶粒度5及偏析2。5等要求偏低；其它如夾雜物級別在國標爲非強制規定，上述因素使熱軋交貨狀態不能很好用當前各類彈簧産品的首道成形工藝，也不能滿足簧産品輕量化、高應力和耐久性的質量要求。

　　鋼鐵企業熱軋型材交貨狀態的

　　後續常用加工

　　球化退火+冷拔。這是比較傳統的彈簧原材料改制法，通過球化退火細化晶粒、均勻化學成分、軟化體；通過冷拔變形提高線材的圓整度、線徑拉伸彈簧精度，低表面粗糙度、表面缺陷、脫碳層等從而提高表面量和彈簧成形精度。“球化退火+冷拔”也可作爲尺、高精度矯直、表面磨光或剝皮的前道工序。但于球化退火工序成本較高，現在行業內盡量去此工以降低生産成本。此交貨狀態主要適用大料徑彈簧生産、熱卷彈簧生産，以及較小線徑冷成形加熱處理的彈簧生産。

　　韌化熱處理。通過彈簧調質熱處理（鉛浴/淬火回火處理）+冷拔變形的一種工藝。一般由專業線材加工企業生産，此類線材特點是非常適用冷卷型彈簧産品制造工藝，同時具有一定的強度和耐久性能。彈簧專業制造企業主要采用這類線材生産各類異型彈簧（卡、拉、扭、壓簧等）。

　　油淬火—回火。執行標准爲GB/T18983—2003。此類線材是彈簧制造企業用于冷成形工藝方式生産高應力彈簧的主要原材料，其特點是較高的抗拉強度和綜合耐久性能。目前，油淬火—回火彈簧鋼絲的深加工途徑有兩類，常用的是冷拔+油淬火—回火和韌化熱處理後冷拔形變+油淬火—回火熱處理。

　　冷拔+油淬火—回火。這類冷拔預處理加熱處理是彈簧線材較爲廣泛的深加工方式，也是冷卷成形彈簧的主要原材料交貨狀態。目前既有專業的生産企業如上海中煉、中鋼院中試等，也有彈簧制造企業自己生産。此工藝方式通常用于較大線徑（Φ8—16mm）鋼絲。實際上，現在的油淬火—回火熱處理中有油淬火也有水淬火，淬火加熱方式有輻射加熱，也有感應加熱，各有利弊，關鍵是最終輸出的線材技術質量，批量生産爲高級線徑8—16mm的油淬火—回火的線材的技術指標已達到Rm2100MPa，Ψ≥35%、表面粗糙度Rz35μm、表面脫碳最深30μm，晶粒度≥10級。常用的高應力彈簧油淬火—回火材料爲Rm2000MPa，Ψ≥40%、表面粗糙度Rz50μm，表面脫碳最深50μm、晶粒度≥10級。普通應用的彈簧油淬火—回火材料爲Rm1800—1900MPa，Ψ≥40%，表面缺陷深度≤200μm、表面脫碳最深100μm、晶粒度≥7級，線材熱處理的質量提升空間還很大。

　　調質處理+冷拔形變+油淬火—回火。這種深加工工藝主要用于彈簧産品技術質量要求高、線徑較細Φ2—6mm的高應力彈簧，經過此工藝深加工，線材具有更高的綜合機械性能，強度、塑性、硬度、韌性和疲勞性能都得到提高。彈簧專業制造企業主要將此類材料用于汽車、內燃機等動力總成系統中的重要彈簧，如：氣門彈簧、變速箱彈簧、離合器彈簧等，其特點是強度高（Rm2200MPa），表面質量好、無脫碳、表面缺陷Rz12μm。

　　冷拔形變強化。此類加工工藝主要適用于不鏽鋼和有色金屬線材，通過形變強化提高線材的強度來滿足彈簧制造企業對材料的要求。彈簧制造企業直接利用此類材料的強度，通過成形、去應力回火和穩定化處理來達到一般機械彈簧需要的機械性能。

會場佈置-燈光音響行業如何面對互聯網時代?

　　目前，燈光音響行業的目標市場帳篷出租還是放在現實環境中，面對互聯網的突襲，卻不得不重視，俗話說，“要跟得上時代的潮流”，世界在變，你還在固步自封，就等著被淘汰了。燈光音響行業如何面對互聯網時代?主要問題還是在于傳統商業模式與新型網絡營銷模式的沖突上，兩者實際上是可以互溶的，沒有孰優孰劣之分，運用得當，便是得到雙贏的局面。

　　眼下，演藝市場相對處于淡季，但大部分人還不太認可“音響燈光行業進入冬天”的說法，畢竟，市場總份額並沒有下降。據地方工程商反應，大型工程雖然有所調整，但50萬以下的小工程多了起來，某些應用領域，如學校、部隊等會場佈置基礎配置以及基層精神文明建設項目反而有所增長。而從企業處所了解，高端會所、大型政府項目有所減少，但量販式KTV、二三線城市娛樂項目等依然大有前景。市場機辦公家具 台中遇一直都存在，但隨著行業發展變化，行業競爭加劇，市場對企業、對商家也提出了更多更高的要求。

　　看清互聯網遊戲規則

　　燈光音響行業如何融入互聯網?首先一個就是要轉變傳統的思維模式。 一些傳統企業在面臨互聯網挑戰的時候，經曆了特別複雜的心路曆程。第一個階段叫看不起。他們覺得互聯網是小玩鬧，成不了大氣。我們幹這個行業都幾十年了。就准備研究。他們就覺得眼花缭亂。他們進入第二個階段：看不清。俗話說外行看熱鬧，內行看門道，對很多非互聯網的傳統企業來說，正因爲他們不了解互聯網的遊戲規則，于舞台架設是進入第三個階段：看不懂。

　　馮侖說，價值觀決定了一個企業的方向。一個企業做得越成功，它成功的東西就塑造了它的基因。很多企業有些誤區，覺得用互聯網，不就是花錢買技術嗎?互聯網有很多大的概念，很多人一講互聯網就是雲計算、大數據、絡、移動終端，好像你花了錢，買了互聯網的技術，就變成互聯網企業了。其實，我覺得那些都是一些戰術。要面對互聯網的挑戰，必須要掌握互聯網的幾個基本價值觀。它們和傳統商業不一樣。

　　互聯網時代是一個消滅信息不對稱的時代，是一個信息透明的時代。在互聯網時代，顧客的消費行爲發生了變化。在沒有互聯網的傳統時期，商家跟消費者之間的關系，是以信息不對稱爲基礎。通俗地講，買的沒有賣的精。

　　傳統的商業裏，講的是：客戶是上帝。在這樣的經濟關系桌椅出租裏，只有兩個維度：一個是商家，一個是客戶。客戶是誰?是花錢買你東西的人。誰向我付錢，他才是上帝。這是傳統經濟的遊戲規則。

　　各種營銷理論，通過産品包裝、廣告推廣、促銷甩賣，都是一個目的，就是要把東西賣給顧客。但是，有了互聯網之後，遊戲規則變了。消費者變得越來越有主動權，越來越有話語權。這種基于信息不對稱的營銷，其效果會越來越小，而用戶的體驗會變得越來越重要。

　　免費是互聯網的精神。從商業遊戲規則來看，互聯網上的産品和服務雖然千變萬化，但掙錢的模式其實就三種，但前提都是必須要有一個巨大的免費用戶群：

　　第一種掙錢方式，是利用互聯網賣東西。如果你賣真實的東西，你可以管它叫電子商務。這種掙錢方式就是以互聯網爲平台，做的還是傳統生意，它只是發揮了互聯網的特點，就是網聚人的力量。對于燈光音響行業，大可以運用網絡這個平台，在互聯網上尋找客戶，既可以節省時間也可節省成本，傳統商務模式裏，我們靠的是往外跑單子接單子，時間成本和網絡是不可比的，當然這也要結合傳統的這種營銷模式，在前期可以在網絡上和客戶有個初步的共識，之後還是要靠業務員去聯系，畢竟現在很多人還是比較相信“眼見爲實”，在後期也可以利用互聯網增強與客戶的聯系。

　　第二種，就是廣告。如果你的服務不能賺錢，但你有足夠多的眼球，有足夠多的用戶，這樣你可以向他們推薦一些其他的産品和服務，實際上這就是廣告。事實證明，網絡廣告帶來的效益不可小觑，廣告就是廣而告之，哪裏是人群聚集點，哪裏就是市場，燈光音響行業也可以利用網絡廣告提升自己的品牌價值。

　　第三種，就是增值服務模式，網遊最典型。你可以向免費用戶中的某些用戶收取增值服務費。舉個例子：在一個網遊裏面，可能有1萬個用戶都是來免費玩，突然來了一個人。他覺得自己與衆不同，他要當帶頭大哥，于是他要花很多錢，他感覺自己在這個空間裏受人尊重。掙高富帥的錢，就是增值服務。這種模式就相當于我們平常看到的商家活動或者展會現場，我們在展示我們的産品同時也必須推出一些免費的活動來吸引顧客，否則難免陷入枯燥冷場的尴尬境地，燈光音響行業接入互聯網，可以把産品活動搬入網絡的虛擬環境中。
