2) LP900 Ceramic Heat Sink
LP900 is a silicon carbide ceramic heat sink and it belongs to the micro-hole structure. Under the same unit area,it can be more than 30% porosity, greatly increasing the heat transfer area with air to enhance its cooling effect. At the same time its heat capacity is small, its heat storage is small and the heat can be more quickly to the outside world. Ceramic heat sink main features: environmental protection, insulation resistance to high pressure, efficient heat, to avoid brewing EMI problems. So it can effectively solve the electronic and home appliance industry thermal and cooling problems, while it is specially for small and medium wattage power consumption, design space pay attention to light, thin, short, small products. What’s more, it can provide technical support and application for electronic products’ innovative and development.
Features & Benefits:
The best electronic insulation and avoid the breeding of EMI problems Light weight book, high surface area, good heat radiation, no heat, heat fast Resistant to cold and heat shock, easy to install, no long-term preservation of the quality problem.
