Liquid cold plate has been relatively popular, for the use of manufacturers, the quality of the water cooling plate can make an objective judgment is to improve the quality of equipment necessary ability. Now let Lori the customized liquid cold plate manufacturer to introduce to you, how to distinguish the quality of cold plate good or bad?

1. Appearance.

A product is like a person, a product is like a character. Clothing reflects your taste and attitude towards life. So does the product's appearance. Basic requirements: uniform chamfer, no burr, comfortable feel, roughness shall not be greater than 6.3 (generally 3.2 for Lori), no oil residue on the surface, no oxidation and discoloration.

2. Material.

In the fierce market competition, in order to reduce costs, some businesses use non-national standard materials for the base plate of liquid cold plate. The base plate of cold plate. is generally aluminum plate, some are made from waste aluminum recasting, which will have impurities sand holes, if used in the air cooling heat sink, the risk is not big, but if used in the water cooling plates, there will be the risk of leakage corrosion. For a liquid cooling plate, the use of non-national standard materials can be hundreds to thousands of yuan, which is why the market price difference of different merchants is an important factor.The source and material reports can be confirmed with SGS reports.

3. Process details

The material can be the same but the process is different, the effect of the  liquid cold plate is completely different, look at the process from these aspects.

(1) . Dimensional accuracy: the accuracy of hole position is generally about 0.1mm with good consistency.
(2). Chamfering method. For an excellent manufacturer, chamfering must be done on the machine to ensure uniformity and consistency.

(3) Look at the deformation amount, especially the flatness of the installation area of core components. Generally, it shall be within 0.1mm in any 100*100mm area, and 0.02mm in those with high requirements.The higher the flatness, the higher the heat transfer efficiency. You can put it on a flat surface with a square ruler and use a feeler to see how big the gaps are.

4. The process of channel formation

Because for liquid cold plate buried copper pipe, copper and aluminum plate through the process of buried pipe connect together, and then by grinding or fly the process for processing, makes the whole piece of water cooled surface to form a smooth surface, whether quality can also be observed from this plane flat, copper and aluminum have fused into a plane, have crack or uneven will affect the heat transfer effect, at the same time, if the joint use the soldering welding, time is long joint leakage is likely to happen, this belongs to the fake inferior products.

5. The packing and shipping。

As the core component of the equipment, water cooling plate is of high quality and high cost.In addition to surface protection, high quality water cooling plate will pay attention to the protection of the channel, generally using a special cover to protect the channel, prevent dust and other foreign matter into the channel. At the same time, for transport packaging, should use wooden case. 

Finally, most importantly, the liquid cold plate must not have leakage and the risk of leakage. Each product must be tested for leakage and also for bursting pressure. For brazing liquid cooling plate due to many welding leakage points, the cavity area may be very large, especially in the case of thin wall.
