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. 

Soldering heat sink is used for welding heat sink fins on the aluminum or copper base plate. The forms of fin can be folded fin or stacked fin and so on.

Characteristics：

1. High fin density, large cooling area and light weight; For the welding of single fin, it is possible to process and groove the bottom plate orplace the fin into the groove for welding, as to maximize the density(spacing up to 1mm) and height(up to 150mm).

2. The base platecan conduct complicated mechanical process. It also can be embedded heat pipes or vampor chamber to improve the ability of stablize temperature.

3. The shape of the heat sink is flexible, which can be conveniently processed with mounting holes and device avoidance bits.

Aluminum extruded heat sink

The aluminum extrusion technology simply means that the aluminum ingots are heated at high temperature about 520-540℃, the aluminum liquid is allowed to flow through the squeeze mold with grooves under high pressure to make the heat sink embryo. Aluminium heatsink extrusion is relatively easy to implement and its equipment cost is relatively low, which makes it widely used in the market. 

The most commonly used aluminum extruding material is aa6063, which has good thermal conductivity and processability. However, due to the limitation of its material, the ratio of thickness and length of the heatsink fin can not exceed 1:18. Thus it is difficult to improve the cooling area in a limited space, and it turns out that aluminum extruded heatsink fin effect is unsatisfying. It seems not surpass the CPU heat sink with high frequency in a short time.

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.
