空气冷却器管束用铝带(L.3)是用来制造空调机散热片的。由于散热片的使用特点对铝带有一些特殊性能要求。该铝带是往一根9米长的无缝钢管上缠绕,要求一根铝带一缠到底,最好中间不接头(允许接一次头的<10％)。要想将铝带缠绕在钢管上,必须先把铝带沿纵向的底部约2毫米弯曲成90°贴在钢管上,其上部分呈螺旋状立在钢管上,目的是散加散热面积,这样,该部分愈往上变形就愈大。要求铝带变形时不出现皱褶,缠绕时不断裂,即为“半硬状态”
Air Cooler Bundles The aluminum strip (L.3) is used to make heat sinks for air conditioners. Due to the use of heat sink on the aluminum with some special performance requirements. The aluminum strip is wound on a 9-meter long seamless steel pipe, requiring an aluminum strip to wrap around to the end. It is best not to be connected in the middle (less than 10% is allowed). In order to wind the aluminum strip around the pipe, the aluminum strip must first be bent about 90 ° to the pipe at a length of about 2 mm at the bottom of the longitudinal direction. The upper part of the strip is spirally erected on the pipe to dissipate the heat so that , The greater the distortion of this part, the greater it will be. Requires deformation of the aluminum does not appear wrinkles, winding is not broken, that is, “semi-hard state”
