Abstract
A heat transfer device generally includes a flexible cooling layer for use in heat pipe technology for example. The flexible layer has outer and inner surfaces. A backing layer has an outer surface and an inner surface facing the inner surface of the flexible layer. A rigid separator portion is disposed between the inner surfaces of the flexible and backing layers, and has inner and outer surfaces. The inner surfaces of the flexible and backing layers and the rigid separator portion define a sealed chamber. An evaporable working liquid is contained within the sealed chamber. The working liquid expands when heated to expand a volume within the sealed chamber, such that the flexible layer extends away from the sealed chamber. The flexible layer, when extended transfers heat through the sealed chamber to a cooler area of the device.
