A thermal management system adapted to vent a two-phase working fluid into an environment having a higher pressure than a vapor pressure of a working fluid corresponding to a set point of the system including a secondary vessel containing a secondary species. The system includes a primary vessel containing the working fluid and the secondary species, and at least one valve to selectively control venting of a mixture of the working fluid and the secondary species from the primary vessel to the environment. The system includes at least one valve connected between the primary vessel and the secondary vessel to selectively control charging of the secondary species into the primary vessel.

Thermal management system

A loop heat pipe evaporator includes a porous primary wick, and a nonporous envelope unseparatingly surrounding the primary wick. The primary wick and the envelope are of one-piece construction.

Loop heat pipe evaporator

An apparatus for dissipating thermal energy including a baseplate including a first body having a first groove and a second groove intersecting one another, the first groove and the second groove formed in and only accessible from a first side of the baseplate. The apparatus including a first heat pipe and a second heat pipe arranged and disposed to provide both an overlapping arrangement and a nonoverlapping arrangement within the first groove and the second groove of the baseplate.

Heat pipes disposed in overlapping and nonoverlapping arrangements

A heat pipe device comprising at least two of the following: an axially grooved bore for thermal transport, the axially grooved bore having an axial groove wick; a phase change material bore for thermal storage, the phase change material bore having internal fins to enhance heat transfer, the internal fins extend along the axis of the phase change material bore; and a porous media bore for accepting high heat fluxes, the porous media bore having a porous media wick in areas of high heat flux.

Multi-bore constant conductance heat pipe for high heat flux and thermal storage

A cool storage system comprising which includes a plurality of heat pipes. Each of the heat pipes has a lower evaporator section, a hybrid evaporator/condensing section, and an upper condensing section. The hybrid evaporator/condensing section positioned between the lower evaporator section and the upper condensing section. Each of the heat pipes contains a selected amount of a heat transfer fluid adapted to transfer heat from the lower evaporator section to the hybrid evaporator/condensing section and the upper condensing section through a vapor/condensation cycle, or the heat transfer fluid is vaporized in the hybrid evaporator and condensed in the upper evaporator section. A thermal storage medium is provided in thermal engagement with the hybrid evaporator/condensing section. A heat source is located in said lower evaporator section, and a cooling source, located in said upper condensing section.

Heat pipe&#x2014;thermal storage medium based cool storage system

A heat pipe assembly that includes at least one axial groove heat pipe and at least one porous media heat pipe. The porous media heat pipe may be embedded into a flange of the axial groove heat pipe, or embedded into a wall of the axial groove heat pipe, or embedded into another bore of the axial groove heat pipe. The evaporator of the at least one porous media heat pipe may be located remotely and can accept a high heat flux, while a condenser of the at least one porous media heat pipe is attached to the axial groove heat pipe.

Constant conductance heat pipe assembly for high heat flux

A heat pipe with a capillary structure that consists of heat conductive capillary grooves in the condenser region that meet with a porous wick in the evaporator section. The embodiments include several structures of the interface at the junction of the porous wick and the capillary grooves. One such interface is a simple butt joint. Others have interlocking shapes on the wick and the grooves such as parts of the wick that fit into or around the grooves.

Hybrid heat pipe

An evaporator for a loop heat pipe with high input heat transfer. The heat transfer is attained by constructing a heat pipe on the loop heat pipe evaporator heat input surface. The heat pipe then distributes the heat from limited input areas over the entire surface of the loop heat pipe evaporator, and that entire evaporator surface functions as the loop heat pipe heat input area as opposed to limited smaller areas into which the heat usually enters.

Loop heat pipe evaporator including a second heat pipe

The apparatus is a capillary loop evaporator in which the vapor space is the internal volume of a cup shaped evaporator wick with sidewalls in full contact with the outer casing of the evaporator. Liquid is furnished to the wick through thicker wick wall sections, slabs protruding from the liquid-vapor barrier wick, eccentric wick cross sections, or tunnel arteries. The tunnel arteries can also be formed within heat flow reducing ridges protruding into the vapor space. The tunnel arteries can be fed liquid by bayonet tubes or cable arteries, and can be isolated from the heat source with regions of finer wick to impede vapor flow into the liquid. Tunnel arteries also enable separation of the evaporator and the reservoir for thermal isolation and structural flexibility. A wick within the reservoir aids collection of liquid in low gravity applications.

Evaporator for capillary loop

A heat transfer loop system includes a primary passive two-phase flow segment with an evaporator, a condenser and a liquid reservoir, and a secondary actively pumped liquid flow segment in which the liquid in the reservoir is drawn by a liquid pump into the evaporator, where a portion of the liquid is vaporized by the heat input and moves into the primary segment while the excess liquid is pumped back to the reservoir. The evaporator consists of a porous wick and one or more liquid arteries encased in the porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The excess liquid continues to move through the arteries and eventually out of the evaporator and into the reservoir. The porous wick provides sufficient capillary force to separate the liquid inside the arteries and the vapor in the evaporator.
