Thermal conductive sheet materials

Abstract

This product is a thermal conductive sheet component used in the manufacture of thermal conductive sheets. Thermal conductive sheets are sandwiched between a heat source component, such as a circuit, and a heat dissipation component, such as a heat sink, in applications such as inverters. The protrusions are made of boron nitride, which has excellent thermal conductivity. Thermal conductive sheets are manufactured by pouring resin into the front surface of this product. This product features multiple protrusions arranged across the entire front surface of the sheet. The protrusions are generally tubular. Therefore, when resin is poured into this product, the protrusions do not collapse or become smaller under pressure. Instead, as shown in the "Reference Enlarged Cross-Sectional Diagram Showing the Usage State," the protrusions remain vertical within the thermal conductive sheet, allowing for efficient heat transfer from the heat source component to the heat dissipation component. This product is approximately 10 cm in length and width when viewed from the front. The square area enclosed by the dashed line is approximately 1.5 mm in length and width when viewed from the front. In typical transactions, enlarged photographs or drawings of the protrusions are attached.
