Pressure compensated cooling radiator for subsea power equipment

A system, comprising:

• a heat exchanger configured to:
• fluidly couple to a subsea transformer station;
• and
• diffuse thermal energy from the subsea transformer station;
• wherein a portion of the heat exchanger is configured to at least partially expand, contract, or a combination thereof in response to variations of a pressure, a temperature, or a combination thereof of a fluid disposed within the subsea transformer station.

A method, comprising:

• transferring a fluid from a subsea transformer station to a heat exchanger;
• diffusing thermal energy from the fluid in response to the fluid flowing through the heat exchanger;
• returning the fluid from the heat exchanger to the subsea transformer station;
• and
• expanding a portion of the heat exchanger in response to an increase in a pressure of the fluid.
