Copper heat sink has its advantages, also have its disadvantages. As is often the case that distributors and manufacturers always introduce advantages of heat sink while the disadvantages are hardly mentioned. However those shortcomings are often the key to solving the heat sink problems.

Large heat sink has great demand for water quality of heat-supplying system. If it has a simple corrosion phenomenon in the unsafe heating system, chip heat sink manufacturers said that consumers should know whether the heat sinks match the residential heat-supplying system before their purchase.

Since water quality of those residential heat-supplying system can not reach the specification, recently companies have begun to take corresponding anti-corrosion measures.

This has been a tough year for the heat sinks suppliers. Large heat sink industry in the war on the battlefield, the future is the battle of soft power. The strong will grow stronger, and the weak will fade away. Now those predictions are coming true. Fixed aluminum heat sink market rise is weak, in the early stage of change, the performance of aluminum heat sink companies slow down the trend. At the same time, the changing environment at home and abroad has put the company under unprecedented pressure to survive.

First, the growth rate is slowing down

Data show that even though the market for heat sinks aluminum in China is still growing steadily, the overall upward trend has slowed down significantly. Aluminum heat sink on the market up slow, the company up drive is insufficient. While the cost of heatsink materials and labor continued to increase, the price of aluminum heat sink continued to decline, resulting in the compression of the profit range, which further affected the performance of aluminum heat sink company.

Second, trade friction 

After more than half a year of trade friction, to a large extent affected the domestic economic growth rate. At the same time, it also restricts the export of Chinese goods to some extent.

The quality assurance, after-sales service of the Led light heat sink is in order to protect consumer interests and make a commitment, and also the important aspect for customers to buy heat sink. So, the large heat sink manufacturers will invest a lot of money in quality assurance and after-sales service. Contrary to this, those heat sink manufacturers of opportunism use false quality to cheat customers.

1.Purchase heatsink from dealers:

Be sure to pay attention to the dealer warranty and manufacturer warranty is consistent. Because the dealer authority is limited, the quality assurance is impossible to do very perfect. And warranty commitment of the dealer is also authorized by the manufacturer.

2.If you buy the Led light heat sink from the Internet:

After understanding electronic heat sink (like electronic cooling plate) relevant information beforehand, inquire the official website of this manufacturer seeing whether it makes the written explanation to the Led light heat sink quality assurance problem. If not, you must call the consultation to fully ensure your interests are not damaged.

3.Claim that there is a physical store but is not:

The real situation may be a small factory with dozens of people, they even need to order products from other manufacturers. It’s not hard to imagine the quality of their assurance and after-sale service. If the economic conditions allow, you can visit the field and then make the purchase.

 LED heat sink manufacturers believe that the surface should be protected, which means its resistance to moisture, salt spray and mold should meet the corresponding LED standards.

Pay attention to water leakage prevention, block prevention while the heat sink is working.

Generally speaking, led heat sinks suppliers have the following requirements for the surface quality of heat sink for Led lights:

1. The surface of the heat sink should be free from shrinkage, corrosion, crack and other defects.

2. Metal fasteners of flat-plate heat sink and conductive plates of water cooled heat sink should be protected by coating.

3. The allowable value of surface roughness of the cooling body table is up to 3.2m.

As electronics have become smaller and more powerful,heat pipe technology has become much more prevalent among industries.Lori is equipped to meet industries’need of the high volume production Consumer Electronics or the research and development for Aerospace & Defense.
 Lori manufactures its own heat pipes and maintains strict quality standards to ensure the longevity and reliability of our heat pipe heat sink.Heat pipes capabilities also include loop heat pipes and high temperature heat pipes.Lori has been performing heat pipe and loop heat pipe life testing on a variety of material systems and heat sink conditions for years.Material systems and heat sink conditions include copper pipe water cooling, copper-water sintered powder,copper-methanol,aluminum-ammonia,natural convection,forced convection,and liquid cooling.

With ongoing lifespan testing on copper-water-sintered power heat pipe systems,Lori has developed proven manufacturing processes that ensure the lifetime and reliability of our heat sink.
