Abstract

See full text

A cooling system that includes an expandable vapor chamber having a condenser side opposite an evaporator side, a condenser side wick coupled to a condenser side wall, an evaporator side wick coupled to an evaporator side wall, and a vapor core positioned between the evaporator side wick and the condenser side wick. The cooling system also includes a vapor pressure sensor communicatively coupled to a controller and a bellow actuator disposed in the vapor core and communicatively coupled to the controller. The bellow actuator is expandable based on a vapor pressure measurement of the vapor pressure sensor.
