Abstract: An oscillating heat pipe device can include a body formed to be at least partially flexible, one or more channels within the body and defined by the body, an evaporator portion within the body at a first end of the one or more channels and in fluid communication with the one or more channels, and a condenser portion within the body at a second end of the one or more channels and in fluid communication with the one or more channels. The body can be configured to flex between the evaporator portion and the condenser portion. The device can include a heat transfer fluid trapped within the channels to transfer heat between the evaporator portion and the condenser portion.

Abstract: A method of fabricating an oscillating heat pipe includes building the oscillating heat pipe with a layer-by-layer additive manufacturing process such that the oscillating heat pipe includes a body of solid material, an array of channels, an evaporator portion, and a condenser portion. The array of channels are disposed in the body and define a continuous loop through which a fluid flows. The array of channels is formed by cavities in the body as the body is formed with layer-by-layer additive manufacturing. An inner surface of a channel includes a flow directing feature that is configured to promote a first direction of flow and that is configured to provide resistance against a second direction of flow that is opposite the first direction of flow.
