1、微軟私有云解決方案微通道換熱器項(xiàng)目商業(yè)計(jì)劃Business Plan for MCHX ProjectD, SD & S2006年8月18日2006.08.18A 普皇1.目兄1. Background1.1 項(xiàng)目背景1.2 Project BackgroundMCHX微通道換熱器）是一種采用全鋁材料制成的高效換熱器。從技術(shù)上說(shuō)，該 項(xiàng)技術(shù)已經(jīng)成熟并且已經(jīng)成功運(yùn)用于汽車空調(diào)系統(tǒng)，包括 R134a和CO臻統(tǒng)MCHXMicro Channel Heat Exchanger) is a high efficiency all aluminum heat exchanger. Technica

2、lly this technology has been mature and been successfully applied in automobile air conditioning system, both for R134a and CO2 system.在過(guò)去的一年半的時(shí)間內(nèi)，銅材的價(jià)格持續(xù)上揚(yáng)，而同時(shí)鋁材的價(jià)格保持相對(duì)的 穩(wěn)定?，F(xiàn)在銅材的價(jià)格幾乎是鋁材價(jià)格的 3.5倍。由于兩種材料間存在著的明顯 的價(jià)格差異，以及微通道換熱器全鋁結(jié)構(gòu)的特點(diǎn)，與傳統(tǒng)的管翅式換熱器（T&FHX）相比較，微通道換熱器具有明顯的成本上的優(yōu)勢(shì)。 在如今價(jià)格競(jìng)爭(zhēng)日趨激烈 的家用空調(diào)市場(chǎng)上，該成本優(yōu)

3、勢(shì)具有足夠的吸引力，讓許多家用空調(diào)生產(chǎn)廠商考 慮采用微通道來(lái)替換管翅式換熱器。In the last one and half years, the copper price soared while the aluminum price kept relatively stable, and the current copper price is almost 3.5 times of aluminum price. Because of the significant price gap between copper and aluminum, there exists, compared

14、of fast response該市場(chǎng)已經(jīng)進(jìn)入了快速增長(zhǎng)的階段，因此快速的反應(yīng)以及迅速的決策是該計(jì) 劃的關(guān)鍵成功因素。The industry has entered into the fast growing phase, and fast response and quick decision are the key success factors for this business.頁(yè)腳內(nèi)容102.目標(biāo)市場(chǎng)及投資規(guī)模2. Target Market and Investment Scale如前所述，該計(jì)劃第一階段的目標(biāo)市場(chǎng)是家用空調(diào)市場(chǎng)?？紤]到微通道換熱器在用作蒸發(fā)器時(shí)仍存在一些技術(shù)問(wèn)題

15、（如冷凝水的排放，回油問(wèn)題等），本商業(yè)計(jì) 劃主要關(guān)注其在單冷空調(diào)中作為冷凝器的應(yīng)用。為了能夠加快該項(xiàng)計(jì)劃的實(shí)施， 中國(guó)（占全球制冷空調(diào)市場(chǎng)70%額）被選為第一階段的目標(biāo)市場(chǎng)。As stated before, the target market for this project for the first stage is RAC industry. Considering there still some technical problems （suchas condensate drainage, oil return, etc.） to use MCHXas evaporator, th

16、e condenser for cooling only type RAC is the major application for thisbusiness plan. In order to facilitate the project quickly, China, which covers 70%of RACproduction in the world, is selected as the target region for the first stage.2.1 市場(chǎng)情況2.2 Market Situation市場(chǎng)規(guī)模Market size2005年中國(guó)家用空調(diào)市場(chǎng)總體規(guī)模1如圖

19、ound 20 m.unit are cooling only type (including window type and split type).單冷空調(diào)的市場(chǎng)趨勢(shì)Market trend for cooling only單冷空調(diào)和熱泵空調(diào)在價(jià)格上的差異保證了市場(chǎng)對(duì)于單冷空調(diào)的需求，因此 單冷空調(diào)市場(chǎng)在未來(lái)仍將保持平穩(wěn)的發(fā)展。根據(jù)對(duì)中國(guó)一些主要的家用空調(diào) 客戶所做的調(diào)查，單冷空調(diào)市場(chǎng)將會(huì)在未來(lái) 5年內(nèi)保持7%勺增長(zhǎng)。The market for cooling only type will keep stable in the future, because the price diff

20、erence between cooling only type and reversible type ensures the demand for cooling only type. Based on the sample investigation for some key accounts in China RAC market, the cooling only market will grow at 7% in the next 5 years.價(jià)格的敏感性Price sensitivity由于在家用空調(diào)市場(chǎng)中激烈的價(jià)格競(jìng)爭(zhēng)，家用空調(diào)的利潤(rùn)目前已經(jīng)十分有限, 空調(diào)廠家對(duì)于配件的價(jià)

21、格都非常敏感。因此，如果一項(xiàng)新技術(shù)能夠?qū)⒊杀窘?低10%其需求將會(huì)非常巨大，而用微通道換熱器來(lái)替代管翅式換熱器來(lái)作 為冷凝器使用也恰恰就是這種情況。Due to the intensive price competition in RAC industry, the margin space for RACis very limited currently and RACOEMsare very sensitive to component price. Therefore, there will be definitely huge demand for substitution if th

22、ere is 10% cost reduction possibility for new technology, and this is exactly the case for MCHXeplacing T&F HXfor condensers.用戶的興趣Customers' interests已經(jīng)有一些家用空調(diào)廠家對(duì)微通道換熱器產(chǎn)生了濃厚的興趣：Some RAC customers have already showed great interests in MCHX technology:松下Matsushita松下對(duì)于微通道換熱器顯示了濃厚的興趣，并且承諾如果該產(chǎn)品成

23、功投 產(chǎn)，會(huì)有大量的需求。Matsushita is very interested in MCHand they promised huge demand if the product is available.海信HiSenseS給海信提供了三種類型的微通道換熱器樣品進(jìn)行測(cè)試(測(cè)試結(jié)果將會(huì)在后面分析)。S provided them three types of MCHXamples for testing (the testing result showed in below pages).TCLTCL當(dāng)TCL了解到相關(guān)的微通道換熱器的消息時(shí)，他們主動(dòng)地和S進(jìn)行了聯(lián)系。TCL conta

25、the MCHX product has prominent advantages which provide it great competitiveness.高效率High efficiency由于微通道換熱器杰出的性能，和傳統(tǒng)的管翅式換熱器相比較，其傳熱系數(shù) 有明顯的提高。根據(jù)在海信的樣品測(cè)試結(jié)果，10孔的微通道換熱器具傳熱效 率平均提高了 59% 4孔的達(dá)到了 47%Because of MCHX' s outstanding performance, the heat transfer efficiency can be improved a lot compared to

26、conventional T&FHX. The sample testing result in HiSense showed an average improvement of 59% for 10-hole MCHX was reached, and 47% for 4-hole MCHX was reached.體積小，重量輕Compact size and light weight由于微通道換熱器的高效的特點(diǎn)，其外形尺寸及重量都比管翅式換熱器要小。 例如，在海信的測(cè)試的微通道換熱器樣品比管翅式的要小20%而重量則輕3040%Because of the high efficie

27、ncy characteristics of MCHX, the size and weight can be reduced compared to T&FHX. For example, the MCHXample tested in HiSense is 20%smaller than T&F HX, and the weight is 3040% lower.制冷劑充注量Refrigerant charge因?yàn)槲⑼ǖ拦艿膬?nèi)容積要遠(yuǎn)小于管翅式換熱器，所以制冷劑充注量也能夠減 少，即使在系統(tǒng)中需要增加貯液器的情況下亦是如此。研究表明，在采用微 通道換熱器作為冷凝器時(shí)，制冷劑

28、的充注量平均將減少 30%Because the internal volume of MC pipe is much smaller than T&F tube, the refrigerant charge can also be reduced, even there might need an additional receiver in the system. Research shows averagely 30%lower charge can be reached because of the introduction of MCHX condenser.將來(lái)如果微通道

29、換熱器的應(yīng)用擴(kuò)大到蒸發(fā)器，則該優(yōu)勢(shì)將會(huì)更加明顯，因?yàn)?蒸發(fā)器中的制冷劑量會(huì)大幅減少，并且系統(tǒng)不需設(shè)置貯液器。If in the future the application of MCHX is expanded to evaporator, this advantage can even be muchlarger considering the charge reduction in evaporator and no need for receiver.成本優(yōu)勢(shì)Cost competitiveness由于銅材和鋁材之前巨大的價(jià)格差異以及重量上的差別，微通道換熱器相比 管翅式換熱器有著巨大

30、的價(jià)格優(yōu)勢(shì)。從樣品的分析可知，其成本只有管翅式(9.52)的57%實(shí)際上，現(xiàn)有的樣品還需要進(jìn)一步完善(通過(guò)減小管壁 厚度以及管的數(shù)量)，這樣成本降低的潛力還能更大。Because of the lower weight and the big price difference between copper and aluminum, there will be great cost competitiveness for MCHX compared to T&F HX. The analysis for the testing sample shows 43% lower cost t

31、han T&F HX ( 9.52). Actually the sample need to beoptimized (by reducing the wall thickness of MC pipe and the pipe number), and the higher cost saving potential can be reached.如果在將來(lái)，我們能將微通道換熱器應(yīng)用于蒸發(fā)器，則成本節(jié)省空間將會(huì)更 大。And if in the future, we can apply MCHXo evaporator, the cost saving space will be

32、much larger.大規(guī)模生產(chǎn)Mass production微通道換熱器的結(jié)構(gòu)決定了該產(chǎn)品適合于大規(guī)模生產(chǎn)。通過(guò)確定一系列的標(biāo) 準(zhǔn)扁管(不同的孔數(shù)和管尺寸)，可以很容易地對(duì)微通道換熱器進(jìn)行標(biāo)準(zhǔn)化， 從而可以通過(guò)調(diào)整扁管數(shù)量來(lái)滿足客戶對(duì)于換熱量的不同需求。而S在低成本大規(guī)模生產(chǎn)方面的經(jīng)驗(yàn)無(wú)疑將給本項(xiàng)目帶來(lái)益處。The structure of MCHXMCpipes and fins) determines that this product is suitable for mass production. It can easily be standardized by defining
