Recently appeared on the market a Beijing emicon Cooling Technology Co., Ltd (hereinafter referred to as emicon company) LED mining lamp radiator production, its outstanding technical advantages and excellent cost performance has caused extensive concern of LED enterprises and dealers, related media have also done a lot of comments. The core advantage comes from the heat dissipation technology emicon radiating technology limited series of high-end technology, in support of this, the radiator excellent cost performance, stability and reliability. In view of this situation, the author deeply visited emicon company, interviewed the company's technology R & D department person in charge Deng Yueguang dr..
Dr. Deng Yueguang is Chinese Technical Institute of physics, Dr. speciality of refrigeration and cryogenic engineering; in 2011 was awarded the America society of mechanical engineers, transactions of the "ASMEJournalofElectronicPackaging 2010-2011" issued by the annual "best paper award". For the liquid metal cooling professionals, our interview began directly into the technical level.
Q: the advantage of simple introduce liquid metal technology and its application in the field of radiation?
Deng Yueguang: liquid metal cooling technology is by the Chinese Academy of Sciences physicochemical Institute in 2002 proposed first in the world and fourth generation cooling technology development, is an original innovation in recent years the international radiation field. The first generation of cooling technology for finned air-cooled, simply say the metal fin is the heat expansion, and then use the fan to heat convection; heat pipe cooling technology for the second generation of heat, it utilizes the evaporation of the liquid boiling reflux, such a process, with aluminum fins and air to flow to heat; the two traditions technology aims at low heat flux condition, such as CPU or LED, the heat flux density is about 5~10 watts per square centimeter, which all belong to the lower heat flux density. Later, with the development of electronic industry, more and more high heat flux density. Such as laser can reach several thousand watts of heat flow density of fingernail sized area. In this case, we need a high-end heat. Radiating way high-end now is the mainstream of the liquid metal cooling water cooling, and we say to another level in the water cooling on the basis, we call him the fourth generation of heat dissipation technology. Heat the way it compared with water advantage is, first metal heat conduction ability is very strong, so the relative water its heat transfer capability is more outstanding. Another advantage is that his cooling process is not any moving parts, long life. As the cooling mode of the fourth generation, it represents the future development direction of the high heat flux cooling.
Q: how do you think the trend of development of liquid metal cooling technology?
Deng Yueguang: the next development direction, is mainly industrial and civilian use of high heat flux heat radiation field. With the development of electronic industry, more and more high heat density radiation demand has appeared in the civil and industrial fields, such as now LED COB light source, CPU and other high-end, rising heat flux density at. Liquid metal cooling technology will focus on high-end radiation field.
Q: advantage emicon industrial and mining lamp radiator has the greatest in the LED industry enterprises and dealers in what place?
Deng Yueguang: first of all in the heat radiating performance, emicon LED radiator in the use of our new liquid metal heat transfer of patent technology, at the same time, the entire LED radiator by our special heat team carried out a simulation study on the performance of all aspects of the analysis, optimization, so the performance of our radiator compared to traditional products is very good.
Then, from the price of speaking, because we are raising the radiator performance, at the same time we optimized its structure, the materials and processes are optimized, cost is reduced. Therefore, relative to the mining lamp radiator on the market more mature, more superior performance in the circumstances, our product prices even lower about 10%-30%.
Finally, for the weight of products, we use the structure and innovative design, weight than traditional products is reduced by 20%-40%. So from this three aspects, we currently do product is the best fitting LED mining lamp manufacturers demand products, the price is very good.
Q: the liquid metal cooling technology can be used for daily activities of mass field? Will produce what kind of effect?
Deng Yueguang: in fact, civilian products high performance liquid metal CPU radiator we developed is a typical, we provide the top of the liquid cooling radiator products for the fancier. At present, the Chinese Academy of Sciences physicochemical where liquid metal applications carried out a lot of research, there are a lot of domestic and foreign media reports, we believe that technology innovation in liquid metal will be gradually applied to the public life.
Ask: whether the liquid metal cooling technology will become the new mainstream standard heat industry?
Deng Yueguang: liquid metal cooling technology will become the mainstream of the new standard mainly depends on the development of the electronics industry. The current mainstream cooling technology is echelon distribution, a finned air-cooled low-end, also have a high-end water / liquid metal cooling. All of these technologies are helping each other and coexist in a long period of time. Liquid metal cooling technology will have been targeting high-end high heat flux cooling field, we will aim at some direction of competitive differentiation.
Q: describe the liquid metal R & D team.
Deng Yueguang: emicon liquid metal cooling technology from the Chinese Academy of Sciences institute. Institute of physical and chemical R & D team in the field of liquid metal in the forefront of the international. The team study
