What is a high-density fins aluminum heat sink?
High-density fins aluminum heat sink has larger heat dissipation area than ordinary aluminum heat sinks. The high-density fins aluminum heat sink increases the heat dissipation area and reduces the thermal resistance between the heat sink and the air to achieve better heat dissipation. The larger the contact area with the air, the faster the heat dissipation, but the thickness determines the amount of heat transfer.
Advantages of high-density fins aluminum heat sink
1) Advantages of thermal conductivity of high-density fins aluminum heat sink: the thermal conductivity of aluminum heat sinks is 237w/m.k, high pressure resistance, and high metal heat. According to the test of the National Testing Center, its metal thermal strength is 2.27W/Kg degree , and its heat dissipation effect is better than that of ordinary aluminum heat sinks.
2) Appearance and modeling advantages of high-density fins aluminum heat sink: due to the wide use of aluminum alloy heat sink profiles, strong artistic influence has been added in the development process, and high-level, elegant, beautiful, fashionable and other elements have been injected into the genes of aluminum alloy heat sinks , is also today's increasingly diverse market, and is welcomed by more people who pursue quality life.
3) Other advantages of high-density fins aluminum heat sink: aluminum profile heat sinks are lighter in weight, easy to transport and install, and have almost zero requirements for system water quality, and do not need full water maintenance. The aluminum profile heat sink uses the principle of a chimney to dissipate heat, and the air guide is indoors, which is opposite to the wall. It is also called a heat sink that does not smoke the wall.
4) Advantages of the processing and production process of d high-density fins aluminum heat sink: the production process of aluminum profile heat sink profiles is complex, and the production processes of aluminum profile heat sink profile manufacturers include extrusion, aging, straightening, surface treatment and other multiple production processes. Because of its advantage of being easy to extrude, it can be extruded into various shapes, so it has a beautiful appearance and strong decoration. In addition, after surface treatment, the aluminum alloy profile heat sink is coated with electrophoretic paint, and the color is round and beautiful.
Graphite heat sink is an accessory of LED street lamps and the main part of LED heat dissipation. When the LED street lamp is lit, it will generate a lot of heat. If it does not dissipate, it will burn out the circuit board. At this time, the graphite heat sink will come in handy. With the rapid development of LED technology, many products on the market tend to be miniaturized, especially the miniaturization of high-power LED products.
Graphite has excellent thermal conductivity, with a thermal conductivity of {{0}}w/(m-k) (equivalent to 2 to 3 times that of copper and 3 to 5 times that of aluminum, and its thermal conductivity far exceeds that of metal materials such as copper and aluminum), and its weight is also lighter than that of copper Aluminum is light, with a density of 0.85-1.9g/cm3 (the density is equivalent to 1/4 to 1/10 of copper, and 1/1.3 to 1/3 of aluminum). Materials processed from natural graphite have better thermal conductivity than aluminum and copper materials. High stability of chemical and physical properties, excellent electrical conductivity, is a heat sink material with excellent heat dissipation performance.
