摘要： A two-phase liquid cooling system for an electronic component comprised of flexible sealed bag which is partially filled with a liquid coolant. Sufficient residual non-condensing gas is maintained in the bag so that some of the gas dissolves in the liquid coolant when the device is not operating and at ambient temperature. During warm-up, the residual gas comes out of solution and creates nucleation sites that assist in initiating boiling. The bag is air and fluid-impermeable, and has sufficient flexibility such that as coolant vaporizes, the bag expands to maintain the internal bag pressure substantially the same as the ambient environmental pressure. The bag may also be provided with a metal heat spreader plate which passes through a wall of the bag and assists with transferring heat from the component to the coolant. The heat spreader plate may be specially treated to allow the flexible bag material to be directly heat sealed to the plate and to provide nucleation sites to enhance coolant boiling.
摘要翻译：一种用于电子部件的两相液体冷却系统，包括部分填充有液体冷却剂的柔性密封袋。足够的残余非冷凝气体保持在袋中，使得当装置不工作并且在环境温度时，一些气体溶解在液体冷却剂中。在预热期间，残余气体从溶液中排出，并产生有助于开始沸腾的成核位点。该袋是空气和流体不可渗透的，并具有足够的柔性，使得当冷却剂蒸发时，袋膨胀以保持内袋压力基本上与周围环境压力相同。该袋还可以设置有穿过袋的壁的金属散热板，并有助于将热量从部件传递到冷却剂。可以特别处理散热板以使柔性袋材料直接热封在板上并提供成核位置以增加冷却剂沸腾。

摘要： A two-phase liquid cooling system has a container structure that has at least one wall with sufficient flexibility that the wall expands as the coolant vapor expands thereby maintaining the internal container pressure substantially the same as the ambient environmental pressure. Coolant boiling overshoot is reduced by allowing residual gases to remain in the cooling system. More particularly, sufficient residual gas is maintained in the system so that some of the gas dissolves in the liquid coolant when the device is not operating and is at ambient temperature. During warm-up, the residual gas comes out of solution and creates nucleation sites that initiate boiling and prevent overshoot. Additional nucleation sites can also be added to reduce overshoot by treating the inside surfaces of the container structure, for example by laser machining, to create nucleation sites.

摘要： A heat pipe (10) which is flexible and thus conformable to the space in which it is to be deployed consists of two or three layers, namely, a relatively thin, highly conductive plate (12) as a bottom layer, a plastic sheet (16) as a top layer and wicking (14) as an optional middle layer. The bottom plate (12) has a relatively high modulus of elasticity and it is stiff, yet ductile. It is preferably made of metal, such as aluminum, or a plastic sheet or plate. To manufacture the heat pipe (10), the bottom (12) and top layers (16) are aligned, with the wicking (14) between them, and sealed together around three edges. Liquid coolant is then added and the fourth edge is sealed. The sealing is preferably performed by heat sealing. The heat pipe (10) may include heat-dissipating fins (36) or ridges on the end of the pipe that operates as a condenser. The opposing end of the pipe, which acts as the evaporator, is positioned proximate to a heat-generating component. In an alternative embodiment, additional layers of plastic and optional wicking are attached to an otherwise exposed surface of the bottom plate. The heat pipe is narrow and can thus be installed in existing space proximate to a heat generating component, flexing and/or elastically deforming as necessary to facilitate installation. Further, the heat pipe can be bent, to conform to the shape of the component.

摘要： A liquid crystal (LC) display monitor has a high luminosity light source to provide good visibility in brightly lit areas. To prevent overheating of the LC screen and other components of the monitor, a two-phase cooler is provided. The cooler consists of two translucent, flexible bag-like containers, each conforming to a different side of the light source. A low-boiling point coolant within the containers absorbs heat from the light source and is partially vaporized. The coolant vapor travels from the containers into a condenser which is external to the monitor cabinet. The condenser draws thermal energy out of the coolant vapor, causing it to condense and return to the containers. The containers provide shock absorption to protect the light source, and the containers or the coolant may have light-scattering properties to provide diffusion of the light. Other alternatives include locating the light source within the containers or placing the container in contact with the LC screen rather than with the light source.

摘要： A two-phase cooling apparatus uses a radioactive initiator to induce boiling in a liquid coolant, thus reducing thermal hysteresis. A radioactive source, such as spent uranium, is immersed in a liquid coolant bath to allow interaction between the emitted radiation and the liquid. A heat spreader plate may be used to conduct heat to the liquid from a unit to be cooled. An interior surface of a coolant chamber, such as the heat spreader plate, may be plated with a radioactive material to induce a high incidence of nucleation sites. A shielding material may also be used to shield the unit being cooled from the radioactive source. The radioactive source material may also be used to retrofit existing two-phase cooling systems.
