Yimi Kang liquid metal promotes the innovation of LED radiator technology

LED radiator technology innovation is imminent

To be fair, traditional heat dissipation technology has been positive for LED companies and customers. The issues of safety, cost performance and applicability have always existed, but due to technical and market reasons, LED heat sinks These two traditional heat-dissipation technologies have been used all the time. Many technical upgrades are actually structural adjustments and performance enhancements. There is no major change or breakthrough in the technical core.

With the further strengthening of the national requirements for production safety and fire safety; the market further enhances the requirements for cost performance and applicability; the further pursuit of cost and technical requirements by LED manufacturers, the traditional technology and actual demand began to be out of touch, the industry The call for technological innovation has changed from a technical reserve requirement to a forced market demand. Under such a background, Beijing Yimikang Thermal Technology Co., Ltd., the world leader in heat dissipation, has successfully developed a world-leading and unique new generation of heat dissipation technology - liquid metal cooling technology, and successfully applied it to it. LED heat dissipation field provides a new cooling technology solution for LED manufacturers and customers in China and the world.

A new generation of liquid metal LED radiator technology turned out

Beijing Yimikang Cooling Technology Co., Ltd. is a joint venture company established by the Beijing Municipal Government, Beijing Yimikang Technology Development Co., Ltd. and the Institute of Physics and Chemistry of the Chinese Academy of Sciences. It is also a national high-tech enterprise focusing on the core technology of “liquid metal”. The company has a liquid metal heat dissipation technology with completely independent intellectual property rights as its core. It has 50 patented technologies and 5 international patents. The company is committed to becoming a leader in high-end cooling and becoming a world-class supplier of liquid metal heat sinks and a supplier of thermal core technology services. The new generation of liquid metal heat dissipation technology is the world's only and industry-leading liquid metal research center jointly established by the Chinese Academy of Sciences and Yimikang.

Compared with the traditional heat-dissipating material, the liquid metal is a kind of indoor temperature and low melting point metal material, which is liquid at normal temperature, has excellent thermal conductivity, electrical conductivity, stable property, is not volatile, safe and non-toxic, and is certified by RosH. This large class of metal materials is the first in the world and has obvious technical advantages. The new generation of liquid metal heat dissipation technology with its core has wide product applicability and high cost performance. It is far superior to traditional heat dissipation technology in many core parameters of heat dissipation technology. . Based on this technology, Yimikang successfully applied this in the field of LED heat dissipation, and launched a unique liquid metal LED heat sink, which has become another innovative heat dissipation technology product in the LED lighting industry.

A number of cutting-edge patent technologies dramatically improve the core performance of LED heatsinks

Based on liquid metal heat dissipation technology, Yimikang liquid metal LED heat sink adopts the internationally leading patented liquid metal composite phase change heat dissipation (LMPC) technology and liquid metal heat sink advanced technology patent technology to create excellent product performance.

One of the most critical liquid metal composite phase change heat dissipation technologies (LMPC) combines liquid metal heat transfer materials with excellent heat transfer properties with advanced heat pipe technology. Compared with the existing traditional heat pipe technology, liquid metal composite phase change heat dissipation technology has higher heat transfer capacity. The heat transfer capability of the liquid metal heat pipe is greatly enhanced by the high-frequency pulsation of the liquid metal in the heat pipe cavity, the complex thermal process such as convection enhancement, and the enhanced micro-scale heat exchange area. Tests have shown that the LMPC technology of the radiator compared to the traditional heat pipe / uniform temperature cavity radiator in thermal conductivity by 20%, weight reduction of 20%, no installation restrictions, thermal shock, strong system operation, international environmental protection A number of leading performances and advantages, including certification and a service life of up to 20 years.

Another patented technology for advanced process of liquid metal radiators consists of two processes. The double-layer heat pipe compacting process seamlessly embeds the double-layer heat pipe into the bottom plate through a superb compaction process to ensure zero distance between the light source and the hot superconducting pipe. Tight fit; the heat pipe riveting process fastens the heat pipe and the fin heat dissipation module by a riveting process, and the heat pipe efficiently and efficiently transfers the heat generated by the light source to the fin heat dissipation module.

Through the above-mentioned technology, the core performance of the Imicom LED heat sink has been greatly improved, and the key parameters such as thermal resistance, weight and size have been greatly improved. Compared with the conventional heat sink, the liquid metal is used. The heat sink has excellent heat transfer performance, light weight of 50%, support for multi-angle installation, reliability of liquid metal heat pipe for independent use, and various technical advantages such as ROHS environmental protection certification. It can be said that Yimikang is a world-class service provider in the field of heat dissipation. Based on the leading liquid metal heat dissipation technology, it has made a milestone contribution to the technological innovation of LED radiators with professional and strong research and development strength.
