Systems and methods for liquid heat exchange for transformers are described. One embodiment of a fluid heat exchanger includes a transformer inlet port that is coupled to a transformer chamber and receives a dielectric fluid from the transformer chamber. Also included are a cooling fluid inlet for receiving a cooling fluid and a finned heat sink that includes a fluid communicator. The fluid communicator may receive, at a first chamber, the dielectric fluid from the transformer inlet port and directs the dielectric fluid across a first plurality of cooling fins. The fluid communicator may receive, at a second chamber, the cooling fluid from the cooling fluid inlet and may direct the cooling fluid across a second plurality of fins, where the fluid communicator separates the first chamber from the second chamber with a solid divider.
