SYSTEMS AND METHODS FOR COOLING MODULE WITH PROGRESSIVE COOLING FINS

A heat sink system includes: a container including a cavity; a housing connecting to the container to cover the cavity, wherein one or more of the container or the housing includes an inlet port, and one or more of the container or the housing includes an outlet port; and a cooling module in the cavity between the container and the housing, the cooling module in a flow of coolant from the inlet port to the outlet port, wherein the cooling module includes: first cooling fins with a first cooling fin geometry, and second cooling fins with a second cooling fin geometry, wherein the first cooling fins are upstream of the second cooling fins along the flow of coolant from the inlet port to the outlet port.
