Components for thermal conductive sheets

Abstract

This article is a component for thermal conductive sheets used in the manufacture of thermal conductive sheets. The uses and functions of the thermal conductive sheet component will be described in general terms below, followed by a description of the uses and functions of the part for which design registration as a partial design is sought. Thermal conductive sheets are used, for example, in inverters, by being sandwiched between a heat source component such as a circuit and a heat dissipation component such as a heat sink. Multiple protrusions are formed on the front surface of this article at equal or unequal intervals. When using this article, multiple protrusions are formed on the front surface, and then resin is poured in to manufacture the thermal conductive sheet. "Reference Figure 1 showing the state of use" is an enlarged view of the state in which multiple protrusions are formed on the front surface of this article. The protrusions are generally tubular in shape. Therefore, when resin is poured into this product, the protrusions do not collapse or fall over due to pressure, and as shown in "Reference Figure 2 showing the state of use," the protrusions remain vertical within the heat conductive sheet, allowing for efficient transfer of heat from the heat source to the heat dissipation component (Note that "Reference Figure 2 showing the state of use" is a conceptual diagram to explain the use and function of the heat conductive sheet component and does not represent the strictly accurate shape). When forming the protrusions, the gas that will be the raw material for the protrusions is brought into contact with the front surface of this product. Next, the use and function of the part for which design registration is sought as a partial design will be explained. More protrusions are formed in the convex parts that come into contact with more gas, as shown in "Reference Figure 3 showing the state of use." Therefore, by arranging the protrusions, areas with a high density of protrusions, i.e., areas with excellent heat conductivity, can be arbitrarily set. This product is approximately 10 cm in both length and width when viewed from the front. The diameter of the protrusions is 100 μm. In normal transactions, enlarged photographs or diagrams of the protrusions are attached to the transaction.
