Lori launched a new cold forged heatsink for 100W LED thermal solutions- LR0018 Cold Forged HeatSink. Using a pin-fin heatsink design for better airflow andsurface area,
the LR0018 Cold Forged Heat Sink features a very efficient 0.89°C/W thermal resistance, appropriate for high performance LED applications up to 100W. Anodized surface treatment gives the LR0018 Cold Forged Heat Sink corrosion resistance, scratch-resistance, and heat tolerance, making it more physically robust than untreated aluminum.
Compared to straight fin designs, the pin fin LR0018 Cold Forged Heat Sink performs well regardless of orientation, making them ideal for lighting applications. A square heatsink shape accommodates square-type lighting fixture designs.The LR0018 Cold Forged Heat Sink's low thermal resistance is achieved through a combination of cold forging as well as high performance materials. Cold forging produces heat sinks with better thermal characteristics and easier assembly than
traditional die-casting or aluminum extrusion.
With the AL1050 aluminum used in the LR0018 Cold Forged Heat Sink, thermal conductivity is 2.36 times better compared to die casting; from 96.2 W/mK to 227 W/mK. Cold forging allows more complex shapes, and the LR0018 Cold Forged Heat Sink is a one-piece design with no assembly required.
Lori's thermal solutions are designed with a focus on cost-effective performance, as well as weight and volume reduction. Lori's LED lighting applications are designed to offer lightweight,
space-efficient cooling at a great value.
When the heatsink standard demand is high, we should choose aluminum heat sink or skiving heat sink, which is because the aluminum heat sink in the process of extrusion forming. Heat transfer rate is very fast, heat attenuation is very small, but many aluminum heatsinks may not fit users’ electronics space planning, sowe may need to selecting refer to the instruction and then process and manufacture.
When standard demand is not that specific. We can choose bonded fin heat sink or soldering heat sink. These electronic heatsinks can work out the shape size and craft according to customer's CAD drawings, which can be called custom heat sink.
According to the development history of the auto industry, all-electric cars full beyond or replace the critical point of internal combustion engine car, mainly depends on the battery energy density and the cost of lithium-ion battery, when reached to these two points, pure electric vehicles can be almost twice as many car fuel efficiency, supplemented by more efficient electric power system. This is also one of the reasons why the industries desire to see the future development of new energy vehicles and the relevant heat sink manufacturing capability, especially aluminum heat sink manufacturing.
The expert analysis of liquid cooling heat sink said that how fast the pure electric car can surpass the internal combustion engine car can not be calculated very accurately. In the past few years, we could tell that lithium battery cost are falling at an annual rate of 7%. It is estimated that the cost of lithium batteries is expected to be close to 1 yuan/Wh in 2020 or 2021.
First of all, 5G development will bring the experience of large bandwidth and HD video, including the first commercial use of drones.
Second, 5G can deepen and widen the smart grid, including intelligent manufacturing, Internet of vehicles, digital medical and other industries. Meanwhile, 5G slicing technology is needed to provide private network.
Last but not least, it is based on the continuous deepening of the application of the Internet, and relevant standards are still being developed.
However, we found that the application of 5G technology in the power industry are still facing many problems. For example, what 5G thermal solutions can be provided?
The heat sinks of LED lights are generally made of aluminum, which can be divided into two categories: stretched aluminum mainly made of aluminum such as AL6060, and die-cast aluminum mainly made of ADC12.
Among them, the thermal conductivity of ADC12 is 96.7w/m℃, while the one of AL6060 and other aluminum materials is 198-250w/m℃. Obviously the latter is better than the former in terms of thermal conductivity.
Though ADC12 die-casting aluminum can satisfy the general requirements of design aesthetics, but the design of the mould can cost a lot.
The cost of tensile aluminum is generally one tenth of the die-casting mold, and its length is also very flexible, but it can not completely occupy the shell of aluminum heat sink factory. Due to the following points: hardness, deformation, appearance can only be tensile type, changeless, can not meet the market appearance demand.
