As eco-friendly automobiles are expanded, electronic control systems are also required to have high performance. Therefore, ECUs and motors, which are essential for electronic control systems, require higher heat dissipation characteristics than conventional ones. In order to achieve high heat dissipation characteristics, it is necessary to improve the thermal conductivity of Heatsink itself, which is directly contacts the heat source and transfers heat quickly among various components. As the conventional Heatsink materials, aluminum alloys which have excellent thermal conductivity characteristics have been applied. In case of low-solute alloy, the thermal conductivity is the highest. However, in the case of automotive Heatsink, a very complicated shape is required, and in order to realize this, it is necessary to manufacture parts by die casting of a high-solute aluminum alloy. As a result, it has lower thermal conductivity than low solute aluminum alloy. In this study, the optimum alloy composition capable of high pressure casting with 7% Si content and T5 heat treatment were applied to achieve thermal conductivity of 178W/mK. This result is a high thermal conductivity characteristic of low-solute wrought aluminum alloy products, resulting in a 38% improvement over ADC12, a commercial die-cast alloy. At the same time, heatsinks for large-capacity motors(BSG) were developed by securing the same castability as ADC12.
