Water-cooling plate has become more and more popular. For the manufacturer, it is necessary to make an objective judgment on the quality of the water-cooling plates. Let me introduce to you how to distinguish the quality of water-cooling plates.
The quality of a product is like a person, because clothing can reflect ones taste and attitude towards life, which is the same as appearance of the product. The basic requirement of the appearance of the water-cooling plate is that its chamfer should be uniform without burrs, the hand should be comfortable, the surface roughness should not be greater than 6.3 and there is no oil residue and no oxidative discoloration.
In the fierce market competition, some merchants use non-national standard materials as substrates for water-cooling plates in order to reduce costs. The substrate of the water-cooling plate is generally an aluminum plate, and some are made by recasting the waste aluminum, and there is impurity trachoma. If it is used on air-cooled fins, there is little risk, but if it is used on water-cooling plates, there is a risk of water leakage. For water-cooling plates, the use of non-national standard materials can reduce the cost. This is an important factor for the difference in quotes between different businesses in the market.
The material can be the same but the process is different, the effect of water-cooling plate is completely different. We can judge the process of water-cooling plates from these aspects. The first is to look at the dimensional accuracy of the water-cooling plates. Its hole position accuracy is generally around 0.1mm, and the consistency is good. The second is to look at the chamfering method of the water-cooling plates. For an excellent manufacturer, chamfering must be done on the machine to ensure uniformity, consistency and beauty. The third is to look at the deformation of the water-cooling plates, especially the flatness of the core component mounting area. In general, if the flatness of the water-cooled plate is higher, its heat dissipation efficiency is higher. You can use a square ruler on the plane and use a feeler gauge to see the gap size.
For water-cooling plates of the buried copper pipe, the copper pipe and the aluminum plate are joined together by the process of the buried pipe, and then processed by the grinding or flying surface process, so that the surface of the whole water-cooling plates forms a flat plane. So, you can judge the quality of its quality by observing whether its plane is flat. Whether the copper tube and the aluminum plate are fused into one plane, whether there is a gap or unevenness between them will affect the heat dissipation effect of the water-cooling plates. At the same time, if the joint between the copper tube and the aluminum plate is soldered, it is likely that the water-cooling plates will leak water for a long time.
As the core component of the equipment, the water-cooling plate is high quality and high cost. In addition to surface protection, high-quality water-cooling plates will focus on the protection of waterways. A special cover is used to protect the waterways from dust and other foreign matter. At the same time, for transportation packaging, it should be packed in wooden cases to prevent damage during transportation. For cross-regional products with high value, it is generally recommended to use SF Express. Most importantly, water-cooling plates must not leak. Each product must pass a leak test and pass the burst pressure test. For brazed products, the cavity area may be large due to the many soldering leak points, especially in the case of thin walls.
