【正文】 result is that in the refrigerant flow and headwind certain circumstances, according to the direction of refrigerant flow for each process in turn reduce the number of flattube method, the condenser has maximum heat, the smallest refrigerant drop and the biggest sub cooling export, using such a layout is the best． In the operating conditions of this study, along with the increase in the number of flat pores, wind speed is constant, the airside heat transfer coefficient decreases and the airside pressure drop increases. The increase in the number of fiat pores Can increase the condenser heat transfer, but the volume of heat transfer and condenser pact is reduced． As the space increases in pitch, the airside heat transfer coefficient and air resistance are decreased． Due to the reduction of airside heat transfer coefficient decreases， the condenser heat transfer decreases. In addition, with the fin height increases， the airside heat transfer coefficient and air resistance reduced． Key Words： Market demand, market dynamics, strategic marketing, market forecast 目 錄 1 引言 ................................................................................................................................... 7 2 當(dāng)前我國汽車市場需求特點 ............................................................................................ 7 汽車銷量創(chuàng)全球歷史新高 ............................................................................................ 7 乘用車需求結(jié)構(gòu)向多樣化發(fā)展 ..................................................................................... 7 重型貨車和大客車引領(lǐng)商用車市場全面增長 ................................................................ 2 小排量汽車需求受政策影響明顯 ................................................................................. 2 3 當(dāng)前汽車行業(yè)存在的主要問題 ........................................................................................ 2 面對的主要短期問題 ................................................................................................... 2 面對的主要長期問題 ................................................................................................... 3 4 影響轎車需求的主要因素 ................................................................................................ 3 來自轎車本身的影響因素 ............................................................................................ 3 來自制造商的影響因素 ..............................................
