目前由于汽车工业的快速发展,,2012年全国汽车产销1927.18万辆和1930.64万辆,同比分别增长4.6%和4.3%,比上年同期分别提高3.8和1.9个百分点,增速稳中有进。产销突破1900万辆创历史新高,已经四年蝉联世界第一。据统计每辆汽车的空调散热器用铝管都在2kg以上,其平行流口琴式汽车空调散热器成本低廉,制冷效果不下于传统铜管制散热器甚至要好于传统散热器的效果,在汽车市场甚至家用空调市场都有不小的市场氛围。铝制散热器技术经过在汽车空调领域得到了充分的验证和技术积累,在生产技术逐渐走向成熟的时候,国外一些大的家用空调生产厂家将目光放到了铝管代替铜管的市场,尤其是平行流口琴的应用上。在2010年随着家用空调巨头日本大金宣布在今后的2--3年内要用铝制扁管替换铜管的消息后,紧接着松下韩国LG爆料已经出对铝管代替铜管技术的研发成功。随即其平行流口琴铝扁管在约整个市场的份额也大大的增加,据不完全统计仅中国国内汽车空调平行流口琴铝扁管就需45000--65000吨(包括维修市场)。而根据韩国LG官方资料上显示其生产单冷家用空调仅在印度市场就需600----800万台空调,需要用的平行流口琴铝扁管的需求量将极大的增加,预计在240万吨左右。但是目前热挤压平行流口琴铝扁管生产需用的模具几乎都是在国外采购,国内生产的热挤压平行流口琴铝扁管大部分仅限于10孔---14孔模具,一些多孔小筋的只能在直推卧式大挤压机上生产,而康风连续挤压机生产家用空调口琴扁管的模具几乎很少。另国外空调厂家都采用高精度铝合金多空扁管材,采用纯铝发展到采用D97.1100.1050A.3003和3104等铝合金,厚度尺寸也有5mm逐渐变为3mm或2mm以下表面采用多种专利涂层技术可以提高管材的耐腐蚀性。因此,空调用平行流铝制扁管的制造生产国产化.系列化.专业化可以节约大量的外汇,降低空调生产厂家的生产成本,提高我国空调工业的水平,具有十分重大的实际意义。
At present, due to the rapid development of automobile industry, the national automobile production and sales in 2012 amounted to 19.2718 million units and 19,306.400 units, up 4.6% and 4.3% over the same period of last year respectively, up by 3.8 and 1.9 percentage points from the same period of last year respectively, showing steady growth. Production and sales exceeded 19 million hit a record high, has reelected the world for four years. According to statistics, each vehicle with aluminum radiator air conditioner radiator are more than 2kg, its parallel flow harmonica car air conditioner radiator low cost, the cooling effect is no less than the traditional brass radiator or even better than the traditional radiator effect, even in the automotive market or even Household air-conditioning market has a small market atmosphere. Aluminum radiator technology has been in the field of automotive air-conditioning has been fully verified and accumulated technology in the production technology gradually matured, some large foreign manufacturers of household air-conditioners will be on the aluminum pipe instead of copper pipe market, especially Parallel harmonica application. In 2010, with the Japanese home air-conditioning giant Daikin announced in the next 2 - 3 years to replace brass with aluminum flat tube news, followed by Panasonic South Korea broke the news has been out of aluminum tube instead of brass technology research and development success. Then its parallel flow harmonica aluminum flat tubes in the market share has also increased substantially, according to incomplete statistics, only China’s domestic auto air conditioning parallel flow harmonica aluminum flat tubes need 45000 - 65000 tons (including the maintenance market). According to South Korean LG official data show that its production of single-cold household air conditioners in India alone will need 600-800 million units of air-conditioning, the need to parallel the harmonica aluminum flat tube will greatly increase the demand is expected to About 240 million tons. However, the current hot extrusion parallel harmonica aluminum flat tube molds used in the production are almost always purchased abroad, the domestic production of hot extrusion parallel flow harmonica aluminum flat tube is limited to 10 holes --- 14-hole mold, some porous The small gluten can only be produced on the straight push horizontal large extruder, while the blow mold for the home air conditioning harmonica flat tube manufactured by Kang Feng continuous extruder is very few. Another foreign air-conditioning manufacturers are using high-precision aluminum alloy hollow tube, the use of aluminum developed to the use of D97.1100.1050A.3003 and 3104 and other aluminum alloy, the thickness of 5mm also gradually become 3mm or 2mm below the surface with a variety of patents Layer technology can improve the pipe corrosion resistance. Therefore, the air conditioning with parallel flow aluminum flat tube manufacturing domestic production. Serialization. Specialization can save a lot of foreign exchange, reduce production costs of air-conditioning manufacturers and improve the level of China’s air-conditioning industry, with great practical significance.
