Patent ID: 7974090

Claim:
A system for cooling an electrically re-chargeable portable medical device for use in a docking station for accommodating said electrically re-chargeable portable medical device, comprising: the docking station including, a non-forced air active cooling unit for maintaining a first heatsink surface at a temperature below an ambient temperature and for having a second heatsink surface at a temperature exceeding said first heatsink surface temperature, a housing for accommodating an electrically re-chargeable portable medical device for re-charging said portable medical device and seating said portable medical device in a position providing thermal contact between said docking station first heatsink surface and a heat spreader of said portable device during re-charging of said portable device and said housing prevents said second heatsink surface from contacting said portable medical device, and a controller for varying a temperature difference between said first heatsink surface and said second heatsink surface based on a sensed temperature based on power consumption during re-charging of the electrically rechargeable portable device and causing the second heatsink surface to directly dissipate heat into the air surrounding the docking station away from said portable medical device.
