      鋁卷在高溫制冷后會出現打卷是怎么回事?

      來源:http://www.mallhometrade.com  發布時間:2022-02-18 15:26:05  

      制冷時候出現彎折狀況,緣故為:一般風冷式的標準下,鋁卷的每個部位與氣體觸碰的傳熱指數均差不多,但由于厚度或樣子不一樣,各部位的熱管散熱速率不平衡,鋁卷生產廠家導致薄壁部或中空管的熱管散熱速率比厚壁部慢,導致它在制冷時候出現向中空部位或壁厚偏厚的部位坎坷的狀況。
      Bending occurs during refrigeration because: under the general air-cooled standard, the heat transfer index of each part of the aluminum coil touching the gas is almost the same, but due to the different thickness or appearance, the heat pipe heat dissipation rate of each part is unbalanced, and the aluminum coil manufacturer causes the heat pipe heat dissipation rate of the thin-wall part or hollow pipe to be slower than that of the thick wall part, As a result, it is bumpy towards the hollow part or the part with thick wall thickness during refrigeration.
      彎折緣故及全過程以下:
      The bending reason and the whole process are as follows:
      1、厚壁一部分溫度降低快,先造成收縮力,薄壁一部分或中空管一部分溫度降低慢,基本上沒有收縮力;
      1. The temperature of part of the thick wall decreases rapidly, resulting in shrinkage force first. The temperature of part of the thin wall or part of the hollow pipe decreases slowly, and there is basically no shrinkage force;

      2、厚壁一部分截面較小,造成的收縮力較小,或被光纜牽引機驅動力清除;
      2. The section of part of the thick wall is small, resulting in small shrinkage force, or it is removed by the driving force of the optical cable tractor;
      3、離去光纜牽引機,溫度再次降低;
      3. After leaving the optical cable tractor, the temperature decreases again;
      4、薄壁一部分或中空管一部分截面很大,伴隨著溫度降低慢慢造成很大收縮力,厚壁一部分溫度已大幅度降低,已不造成收縮力或收縮力較小;
      4. A part of the thin wall or a part of the hollow pipe has a large section, which slowly causes a large shrinkage force with the decrease of temperature. The temperature of a part of the thick wall has been greatly reduced, which does not cause shrinkage force or small shrinkage force;
      5、鋁卷橫截面上遭受的收縮力尺寸不勻,沿擠壓成型方位往薄壁一部分或中空管一部分彎折。
      5. The shrinkage force on the cross section of the aluminum coil is uneven, and it bends to a part of the thin wall or a part of the hollow tube along the extrusion direction.
