Ceramic heat sink is a green environmental protection material. It belongs to microporous structure, which can increase the porosity by 30% under the same unit area, greatly increasing the heat dissipation area in contact with air and enhancing its heat dissipation effect. At the same time, its heat capacity is small, its own heat storage capacity is small, and its heat can be transmitted to the outside world more quickly. The main characteristics of ceramic heat sink are environmental protection, insulation, high voltage resistance, efficient heat dissipation, and avoiding EMI problems. It can effectively solve the heat conduction and heat dissipation problems in the electronics and home appliance industries. At the same time, it is especially suitable for products with small and medium watt power consumption and light, thin, short and small design space. It can provide technical support and application for the innovation and development of electronic products.
