Abstract
Heat sinks that cool electronics are mounted within a subsea housing or vessel. Springs are used to provide pressure between the heat sinks and a vessel wall. Vessel wall deformation caused by external seawater pressure is absorbed by the springs, which maintain a pre-load force according to the spring characteristics. The mechanism also allows for rack mounting of the electronics without the need for manual access in the relatively compact vessel or housing.

A system, comprising:
- a heat sink;
- and
- a biasing assembly configured to selectively increase or decrease a biasing force against the heat sink toward a wall of a housing.
A system, comprising:
- an actuator;
- and
- a plurality of biasing devices coupled to the actuator, wherein each of the plurality of biasing devices is responsive to the actuator to selectively increase or decrease a biasing force against one of a plurality of heat sinks.
