Abstract
A prosthetic socket cooling system and method includes a thermally conductive heat spreader including a curved shaped portion configured to maximize contact with a residual limb of a user. A heat extraction subsystem is coupled through a wall of the prosthetic socket and to the thermally conductive heat spreader and is configured to maintain a desired temperature inside the prosthetic socket.
