New Breakthrough in Industrial Application of LED Graphene Graphene: Graphene Heat Dissipation Casting Comes Out

Graphene is known as the "king of materials" of the new century. Both in the materials industry, investment industry, and even the general public have given high attention. However, the high preparation cost of graphene greatly restricts the development of the graphene industry. With the scaling up of graphene preparation processes, the production capacity of graphene has further increased, making it possible for this new material to be widely used in the industrial sector.

In traditional LED manufacturing, aluminum profile castings are usually used, accounting for 40% of the entire lamp product. Faced with the fierce reshuffle of the LED industry, the manufacturing industry's desire to use new materials and reduce costs is particularly prominent. Although the industry uses many methods such as adding thermal conductive plastics and all plastic heat dissipation, they are all based on sacrificing the lifespan and reliability of the lighting fixtures. With the rise in raw material prices in the aluminum industry, especially the elimination of high-energy consuming industries such as electrolytic aluminum, the cost of optoelectronic enterprises has further increased.

The R&D team stated that over the course of two years, relying on the Department of Physics at Xiamen University and the Wuxi Graphene Industry Base, they have tested the properties of over 600 types of graphene and accumulated a large amount of experimental data. Successfully doped various phases of graphene into various polymer products.

This releaseGraphene new heat dissipation casting profilesIn terms of performance, it is comparable to cast aluminum: the thermal conductivity of traditional aluminum parts is 60-70W/(m · K), while the thermal conductivity of graphene new heat dissipation casting profiles reaches 85W/(m · K).

Traditional aluminum profiles face many constraints in structural design, while graphene casting series materials can be made in various shapes, giving optoelectronic structural engineers more choices in design. The structural design advantage makes this radiator have better heat dissipation performance than aluminum profiles.

In terms of overall cost, the proportion of aluminum is 2.7, but the proportion of graphene castings is only 1.68. In terms of industrial cost accounting, it is 30% lower than the cost of aluminum profiles.

It is reported that this radiator has passed internal tests of several domestic LED companies as early as two months ago, including various related industry application testing standards such as weather resistance testing, including thermal deformation, acid-base environment testing, etc. And bulk delivery has already begun.

Based on the existing 30 watt street lamp module, the measured data shows that the heat dissipation performance of this radiator is very close to that of 6063-T5 aluminum profiles.
