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.
Claims15
An oscillating heat pipe device, comprising:
- a monolithic body formed to be flexible;
- one or more channels within the body and defined by the body;
- an evaporator portion within the body and in fluid communication with the one or more channels;
- and
- a condenser portion within the body spaced from the evaporator portion and in fluid communication with the one or more channels, wherein the body is configured to flex at least between the evaporator portion and the condenser portion, wherein the body is made at least partially of a flexible material, wherein the flexible material includes at least silicone, wherein the flexible material is thermally insulative, wherein a heat transfer coefficient of the device is higher than that of the flexible material alone, wherein a dimension of the one or more channels and a thickness of the body are selected for the device to act as a thermal conductor.
An electrical apparatus, comprising:
- one or more electrical components that generate heat in use;
- and
- an oscillating heat pipe device disposed on the one or more electrical components and configured to transfer the heat from the one or more electrical components, the device comprising:
- a monolithic body formed to be flexible;
- one or more channels within the body and defined by the body;
- an evaporator portion within the body and in fluid communication with the one or more channels;
- and
- a condenser portion within the body spaced from the evaporator portion and in fluid communication with the one or more channels, wherein the body is configured to flex at least between the evaporator portion and the condenser portion, wherein the body is made at least partially of a flexible material, wherein the flexible material includes silicone, wherein the flexible material is thermally insulative, wherein a heat transfer coefficient of the device is higher than that of the flexible material alone, wherein a dimension of the one or more channels and a thickness of the body are selected for the device to act as a thermal conductor.
