3. Responsibility/职责

3.1 PE(Production Engineer) and project engineer are responsible for define the operating

parameters. /工艺工程师和项目工程师负责定义操作参数。

3.2 Production workers are responsible for operating coating according to this work instruction and

checking the coating result by themselves. /生产部操作工负责按照本作业指导书作业并且

实施自检。

3.3 Inspector of QA dept. is responsible for monitoring the coating process and checking the

4. Procedure/程序

4.1 Cleaning of the fins: /翅片的清洁：

4.1.1 Make sure that the ventilators or other parts which will affect the pro-treatment of

aluminum fins are not assembled or they have been dismantled. /确认芯组两边的风机

或者其它影响铝翅片预处理的部件未装配，或者已经装配但是现在已经拆除。

4.1.2 If a thick dust blanket is present on the coil, use a vacuum cleaner with soft brush

attachment first, before cleaning the coil with water and detergent. /如果芯组表面覆盖

了很厚的灰尘，则必须在用水和清洁剂去污脱脂之前，先用带软刷头的真空吸尘

器除尘；

4.1.3 Detergent maker: Blygold. Detergent type: Refa Coil Clean. Detergent shall be diluted

with water to a ratio of 1:10. The cleaning unit shall be: max. 120 bar and max. 80℃. /

清洁剂的品牌：Blygold公司。清洁剂的型号：Refa Coil Clean。清洁剂和水的配比

：1：10。清洗设备最大压力：120公斤，清洗设备最高出水温度：80摄氏度。

4.1.4 When washing the coil, do not aim the pressure washer directly at the coil when initially

squeezing the trigger. Squeeze the trigger with the gun pointing at the floor and, while

spraying, redirect it at the coil surface to be washed. Failure to do this may result in

damage to the fins. /在最一开始打开清洗设备的喷头时，千万不能将喷头直接对着

芯组。必须将喷头对着地面，待水流稳定后方可将其对着盘管进行清洗作业。如

果不按照此规定作业，从喷头里瞬间冲出来的清洗液有可能将盘管上的翅片损坏

。

4.1.5 Place the coil in a vertical position. Followings are the photos which show how to clean

the coil with water and detergent step by step. /将盘管竖立放置，以下是清洗步骤示意

图。

4.1.7 Clean the coil in the opposite direction of the airflow. That means the direction of the

water beam shall be same as the direction of airflow which is forced by ventilator. /在气流相反的方向的一侧清洗翅片，也就是说，从喷枪里出来的水柱方向必须与散热器运行时的气流通过翅片的方向一致。

4.1.8 The Coil Clean detergent must penetrate the coil completely. Distance of the spray gun

to the coil depends on the type and dimension of the coil. Waiting 5 to10 minutes for

using water clean after the bundle has been degreased. Distance of spray gun to the coil depends on the type and dimension of the coil.For cleaning, it’s better to use too much water and Coil Clean than too little. /清洗液必须彻底贯穿翅片。芯组在用清洗剂去油脂后，必须等5～10分钟再用水清洗。喷枪离芯组距离取决与芯组的形状和尺寸。

对清洗来讲，多用一些水和清洗剂比少用好。

4.1.9 Keep water beam pointing between the fins and move the gun along the tubes without

waving it. /必须始终保持喷头出来的水柱在翅片之间，并且沿着铜管的方向平直地移动喷头，不能抖动。

4.1.10 Repeat chapter 4.1.5 from step 1 to step 4 three times with water and detergent. Then

wash the coil with only warm water until all the foam is removed thoroughly. /对于条款4.1.5所描述的步骤1到步骤4，重复执行三次。然后用且只能用温水冲洗盘管，直至所有的泡沫都被清除干净。

4.2 Aligning the fins: /翅片的修整：

After pre-treatment of fins, use a proper FPI fin comb to straighten any bent or misaligned fins.

Make sure the comb is free of dirt and grease. /完成翅片的预处理后，使用合适片距的翅片梳来梳理倒伏的翅片或方向不正的翅片, 使用前要确认梳子上无灰尘及油污。 4.3 Drying of the coil: /芯组的干燥：

4.3.1 After aligning the fins, blow the excessive drops of water on the fins with compressed

air. /翅片修整完毕后，用压缩空气将翅片上残留的多余的水珠吹掉。

4.3.2 It is possible to dry the coil by leaving it into the air for long time. /将芯组暴露在空气

中，可以让其自然干燥。

4.3.3 Drying in a well-ventilated cabin will decrease drying time significantly. /将芯组暴露在

通风良好的烘干室中可以显著的缩短盘管的干燥时间。

4.4 Inspection method of the drying of the coil: /芯组干燥程度的检验方法：

4.4.1 First, check the coil by eyesight to make sure that there is completely no water drop

remaining on the fins. /首先，目视检查芯组，确认翅片上彻底地没有残留的水珠。 4.4.2 Then take a pH paper and gently insert the pH paper at an angle of approx. 45°

between two fins on the lower part of the coil. /然后，取一张pH 试纸，将其以45°左右的角度塞进盘管底部的两片翅片之间。

4.4.3 Check the pH paper for discoloration due to contact with moisture. If the color of the pH

paper is not changed shown as the picture 08, it means the coil is in 100% dry. If the color of the pH paper is changed shown as the picture 09, then it means the coil has the moisture inside. /检查pH 试纸的颜色变化，如果pH 试纸的颜色没有变化，这表明盘管100%的干燥，见图08；如果pH 试纸的颜色的变化如图09所示，这表明芯组内还残留有水汽。
