A thermal interface material includes, in one exemplary embodiment, a polymer, a phase change material, a first thermally conductive filler having a first particle size, and a second thermally conductive filler having a second particle size. The first particle size is larger than the second particle size. A formulation for forming a thermal interface material and an electronic component including a thermal interface material are also provided.

Composite materials comprising a phase change material (PCM) and a macroscale 3D carbon nanotube material, such as a macroscale 3D heteroatom-doped carbon nanotube material, including boron doped carbon nanotube materials, and methods for using the composite materials in various applications where temperature control is critical. Heteroatom-doped carbon nanotube sponge materials are strongly oleophilic, and can soak up large quantities of organic PCMs. One representative application for the composite materials is in thermal energy storage (TES) systems for shipping and storage of pharmaceuticals, medical and life science products.

A nested temperature regulation device includes a watertight pouch having a gas valve, a first plurality of reactive spheres and a rupturable fluid bag. The first reactive spheres are configured to create an endothermic reaction or an exothermic reaction for a set period of time when engaged by the fluid. At least one soluble barrier is positioned within the pouch and includes a hollow interior space that contains another plurality of reactive spheres. Each soluble barrier is constructed to dissolve and to permit the fluid from the bag to engage a subsequent plurality of reactive spheres after a predetermined period of time that is equal to the effective reaction time of the plurality of reactive spheres immediately previously engaged by the fluid. One or more of the plurality of reactive spheres includes a coating that delays the fluid from accessing the reactive material of the sphere having the coating.

This present disclosure provides a vessel assembly for use in temperature sensitive shipping that can maintain a payload temperature across a range of temperatures. The vessel assembly of the present disclosure comprises a vessel having a single chamber, in which a plurality of PCMs are in contact, but immiscible, with each other. The present disclosure reduces the overall packaging materials used in a shipper box and prevents the “wrong” mixture of PCM-containing vessels from being used.

A coolant for a subtractive machine process, the coolant comprising a phase change material which changes from a solid state to a liquid state as a result of frictional heat generated during the subtractive machine process of the machine tool on a component to be machined, and returns to the solid state as the component cools.

A phase change material includes a salt-water solution having a first salt, a second salt and water; a gelling agent; a thermal conductivity enhancer; and a nucleation agent. The phase change material is suitable for use as a cold storage material, in particular, for maintaining an environment at a temperature of from −15 to −40° C.

A heat exchange system including an icephobic heat exchanger (IHEX) tank, a phase change material (PCM) held in the IHEX tank, an immiscible liquid layer held in the IHEX tank, a heat exchanger located within the immiscible liquid layer, and a distributor located above the heat exchanger configured to introduce a plurality of liquid PCM droplets into the immiscible liquid layer. The system further includes a transfer mechanism configured to remove PCM from the IHEX tank, and an external storage tank configured to receive the removed PCM. The immiscible liquid layer has a density lower than a density of both the solid and liquid PCM, and the PCM and the immiscible liquid layer meeting at a PCM-immiscible liquid interface.
