Heat sink is a kind of heat dissipation device for heat-prone electronic components in electrical appliances. Is the terminal point of heat transfer in the equipment. The heat dissipation capacity of the heat sink directly determines the success or failure of the whole product.Heat dissipation efficiency of bonded fin heat sink and heat conductivity of fin material. Heat sink material is related to heat capacity of heat sink medium and effective heat sink area of heat sink. Bonded fin heat sink material refers to the specific material used by the fin. Each material has different thermal conductivity, ranking from high to low, namely silver, copper, gold, aluminum and iron.

At present, the commonly used heat sink material is copper and aluminum alloy. It is recommended to choose the heat sink made of aluminum alloy, which is more cost-effective and lighter in weight.Which tooth heat sink company is reliable? I recommend LORI technology. Shenzhen Lori Technology Co., Ltd. is the manufacture of electronic heat sink, aluminum profile heat sink, aluminum heat sink, automobile heat sink, die casting aluminum heat sink, silicon heat sink

Skiving heat sinks are involved in many fields (such as large servers, computers, frequency converters, automobiles, refrigerators, large machines, medical, communications, radio and television equipment, military industry, etc.).
Skiving fin technology originated from abroad, mainly used in aerospace, military, precision machine tools, electronic equipment and other sophisticated or high-precision industries.With the progress of science and technology and processing technology, Skiving fin technology has been gradually transferred to civilian use and applied to IT and industrial heat sink manufacturing industry.The principle is a whole piece of copper or aluminum according to needs, with a professional skived fin machine cut out the standard spacing of heat sink fin, because of the use of precise skived fin technology, integrated manufacturing, heat transfer medium stability, heat sink thickness is greatly reduced, under the same conditions the heat transfer effect is 200% of the traditional heat sink.Thus can greatly improve the heat transfer efficiency and extend the service life of heating components.

1. Integral molding, no thermal resistance, heat dissipation effect is very stable.

2. Can be a small number of diversified production, no mold costs.
3. Product thickness and spacing can be adjusted arbitrarily (as long as it is within the skived fin range)
4. The most important thing is that the weight will be reduced by more than 30%.
5. For products with the same parameters and the same heat dissipation conditions, our products have a good heat dissipation effect of 5-8 degrees.

Meanwhile skived fin are especially suitable for a small number of diverse products, the cost of mould is less than the investment of heat sink in aluminum extrusion, soldering, bonded fin and other processes.The minimum order quantity requirements for the order is lower, more convenient to meet customer needs.

Lori skived heat sink current capacity:

1. Within 200 mm width is about 80,000 pieces in a month.
2. Within 350 mm width is about 20,000 pieces in a month.
3. Within 500 mm width is about 10000 pieces in a month.

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.

BGA cooling problems get more and more people enough attention, LORI a China heat sink manufacturer has launched a series of heat sink products on the market, BGA memory heatsink is a heatsink set specially designed for BGA chipset, well liked by customers, this heat sink product is Lori's first chip cooling product for a single chip in a long time.

Although these two heat sinks are designed to BGA encapsulated chip cooling, the material and the price are different, one is made of aluminum, while the other is made of pure copper, so the prices are far different.

We know that there are not many memory cooling modules that can be used for BGA packaging in the market before, and most players have to DIY. Now Lori has launched a cooling module that can be used for BGA packaging video memory.

As for bga heat sink modeling, you can match and put it in any way according to different cooling interfaces, so as to achieve ideal regional cooling effect. It is worth noting that this heat sink module is not only easy to install, but also the most important thing is to ensure the compatibility with the cooling device of the video card introduced by LORI, such as the water cooling plate of LORI's video card and the heat pipe cooling.
