Seven advantages of composite die cast aluminum heatsinks

Professor lu bin, deputy director of the institute of building environment and energy conservation, Chinese academy of building sciences, expressed his appreciation for the success of the research and development of the composite die-cast aluminum heat sink. He published a research report recommending that the composite die-cast aluminum heat sink has the following advantages in structure and performance:

1, corrosion resistance, high pressure resistance, durable, suitable for different water heating system.

2. Simplified the composite process of heat transfer resistance and tube expansion, and improved the overall heat dissipation performance of the heating system.

3. Superior thermal performance and high metal thermal strength.

4. Avoid the heat dissipation airflow to smoke the wall, and the heat dissipation effect is excellent.

5, free assembly, flexible assembly, easy installation.

6, heat sink body surface without volatile harmful substances, will not cause harm to the environment and human body.

7, simple, beautiful, generous, can be in harmony with home decoration, symbiosis, safe and reliable. Qingdao university of science and technology professor shuang-xi zhang also for compound die casting aluminum heat sink approvingly, he said: two pipe die casting aluminum heat sink, as a new type of high-grade heat sink, in the guarantee of the beautiful sex without fear of bad water quality at the same time, both advantages of steel and aluminum alloy heat sink, with large investment, large-scale, big development characteristics, can promote the industry long-term stable development, to speed up the development.

Aluminum profile heat sink

Aluminum profile heat sink is also known as aluminum heat sink or sunflower aluminum profile, aluminum profile heat sink with beautiful appearance, light weight, good heat dissipation performance, energy saving effect. LORI THERMAL, relying on long-term accumulated technical experience and production process, set aluminum alloy profile with better thermal conductivity and other characteristics, developed to meet customer requirements for product differentiation, specialization and personalized customized aluminum profile heat sink. The finished aluminum heat sink surface is anodized to improve the corrosion resistance, wear resistance and appearance of aluminum. 

At present, the commonly used types of heat sink aluminum profiles in China are: electronic, electrical, computer heat sink aluminum profiles, sunflower aluminum profiles, power semiconductor heat sink profiles and so on.

Aluminum heat sink because of its superior performance is widely used in: machinery, automobile, wind power, construction machinery, air compressor, railway locomotive, household appliances and other industries.

Aluminum Extruded Heat Sink

Aluminum extrusion (Extruded) technology: as containing the highest amount of metal in the crust, the low cost is its main features, and because of the aluminum extrusion technology and equipment costs are relatively low. So the aluminum have long been used in the heat sink market. Simply put, aluminum extrusion technology is to heat aluminum ingots to about 520~540℃ at high temperature, under high pressure to let the aluminum liquid flow through the extrusion mold with grooves, to make the first heat sink. Then, after cutting and cutting the first heat sink, the heat sink we often see is made. AA6063, which has good thermal conductivity (about 160~180W/m.K) and processability, is the most commonly used aluminum extrusion material. However, due to the limitation of its own material, the ratio of fin thickness and length cannot exceed 1:18, so it is difficult to improve the heat dissipation area in a limited space. Therefore, the heat dissipation effect of aluminum extruded heat sinks is relatively poor, and it is difficult to be competent for today's increasingly high frequency CPU.
