Abstract
A heat pipe cooling plate in which one or more heat pipes sandwiched between cover plates is an expandable heat pipe made with thin flexible walls forming the heat pipe casing. One advantage of such an expandable heat pipe within the cooling plate structure is that the heat pipe need not be bonded to the outer casing. Instead, the heat pipe balloons out when the vapor pressure increases upon heating, and the flexible heat pipe casing moves into intimate contact with the boundary surfaces of the cooling plate.
