1. A method for liquid heat exchange for transformers comprising:
receiving a dielectric fluid from a transformer, wherein the dielectric fluid has an elevated temperature;
receiving a cooling fluid;
directing the dielectric fluid across a first plurality of cooling fins in a first chamber;
directing the cooling fluid across a second plurality of cooling fins in a second chamber, wherein the first chamber and the second chamber are coupled via a solid divider, wherein the solid divider is configured as a thermal conductor to communicate heat from the dielectric fluid to the cooling fluid, and wherein the solid divider prevents the dielectric fluid from physically contacting the cooling fluid;
returning the dielectric fluid to the transformer; and
disposing the cooling fluid after receiving heat from the dielectric fluid.
