Abstract
A phase change cell includes a housing enclosing a phase change chamber that holds a phase change material and a gas pocket. The housing includes a side wall extending between first and second end walls. A capillary is disposed in an interior surface of the side wall. In response to heating of the phase change cell, the capillary is configured to draw the phase change material in a liquid phase towards the periphery of the phase change chamber. A temperature sensor is coupled to the housing in a vicinity of the capillary to measure the phase change temperature. According to another aspect, the housing includes a moveable surface that bounds a portion of the phase change chamber. The phase change temperature of the phase change material changes based on the position of the moveable wall.
