影响彩涂铝卷板冷却弯曲的因素

彩涂铝卷板与我们的生活息息相关,在很多地方都可以看到。彩涂铝线圈及其防腐保温特性在建筑行业中得到了广泛的应用。有时铝卷会弯曲。影响彩涂铝卷冷却弯曲的主要因素有四个

1彩涂铝卷板高压喷嘴方向性强,雾角在25°~30°左右,能完成铝卷的局部冷却,不影响彩涂铝卷的其他部分。
2在正常情况下,空气和铝空心线圈相互接触,传热系数相同。预涂铝卷的壁厚或形状不同,各部位冷却速度不均,使厚部空心管或冷却速度慢于薄件。
三。对于彩涂铝卷板,高压环境空气雾化水,通过接触增加水和型材的表面产物,在水和高温结构型材接触时破坏蒸汽膜,提高传热效率
4彩涂铝卷板采用高压气溶胶冷却时,由于空气和水的存在,水的传热系数大于空气。因此,铝盘片可以提高散热率。

Aluminum coil is closely related to our life and can be seen in many places. Color coated aluminum coil and its anti-corrosion and thermal insulation characteristics are widely used in the construction industry. Sometimes the aluminum coil will bend. There are four main factors affecting the cooling bending of color coated aluminum coil

1. The high pressure spray nozzle has strong directionality, and the angle of fog is about 25 ° to 30 ° and can complete the partial cooling of aluminum coil without affecting other parts of color coated aluminum coil.
2. Under normal conditions, the air and aluminum hollow coils are in contact with each other, and the heat transfer coefficient is the same. The pre painted aluminum coil has different wall thickness or shape, and each part of the cooling rate is uneven, which makes the hollow tube or cooling speed of the thick part slower than that of the thin part.
3. For the color coated aluminum coil, the high pressure ambient air atomizes the water and adds the surface product of water and profile through touching, which destroys the vapor film when water and high temperature structural profile touch, and improves the heat transfer efficiency
4. When some high-pressure aerosols are used for cooling, the heat transfer coefficient of water is greater than that of air due to the existence of air and ater. Therefore, aluminum coil plate can improve the heat dissipation rate.
