红酒柜使用散热风扇如何解决噪音?

众所周知,在酒柜、橱柜这类相对封闭的设备中,工作时设备内各大部件都会长时间运行,因此会产生大量的热源,如果没有及时通风散热,就会导致设备过热烧毁,造成一些电线短路,所以大部分都会使用散热风扇来帮助设备散热。
红酒柜使用散热风扇如何解决噪音?
案件详情
下面我们来分析一下酒柜散热风扇产生的噪音以及如何解决呢?


1、一般情况下是由于散热风扇轴承缺少润滑引起的,及时给风扇轴承加润滑脂可以解决风扇转动噪音的问题。
2、由于风扇叶片不平衡,导致叶片在转轴上松动或轴承间隙过大,个别风扇叶片工作时间长了,脏了要及时清洗,如果风扇叶片有缺陷,不对称或风扇轴承间隙过大,需要更换新的电源风扇,才能解决噪音问题。
3.冷却风扇运转时遇到气旋障碍物而产生的噪音,特别是关键进风口及出风口周围,应避开障碍物。
4、选择冷却风扇时,考虑排热量,尽量选择低转速比大规格的冷却风扇。与小型高速旋转的冷却风扇相比,大规格的通用低转速冷却风扇在输送相同排风量时,噪音较低。
5、机柜内冷却风扇的工作电压是决定电风扇噪音的关键,工作电压越高,震动越大,因此噪音也越大。
6、散热风扇轴承的使用也在一定程度上决定了风扇的噪音,如果使用了劣质的轴承,使用一段时间后,由于轴承磨损,风扇运转时也会产生噪音。轴承的精度越高,与轴芯的摩擦力越小,尺寸配合越精确,噪音当然就越小,这与轴承的材质有很大的关系。
7、所以在选择酒柜散热风扇的时候如果预算充足的话,那么一定要选择好一点的轴承,这样风扇的使用寿命才会更长,而且在后续的使用过程中风扇的噪音也会更低。
