Computer-implemented method for designing a heat sink

A heat sink designed according to the steps of:

• generating a first mesh of the container, said first mesh comprising elements defining a discretized shape of the container in a massive state;
• generating a heat map of the container by imposing a thermal load of the component on the first mesh thereby identifying one or more thermal spots;
• repeatedly solving fluid flow equations and energy equations imposed on the first mesh through a topology optimization method by minimizing the heat sink thermal resistance and/or maximizing the heat sink thermal uniformity;
• characterized in that
• the method further comprises prior to the solving step, the step of
• imposing a channel for the coolant on the first mesh by connecting the inlet with the outlet via one or more of the one or more thermal spots thereby identifying obstacles within the first mesh for the coolant;
• and wherein the solving step is up front performed on elements associated with the channel.
