A heatsink may include multiple fin portions soldered together. The fin portions may have stair-stepped surfaces that provide improved thermal dissipation over conventional singular block heatsinks. The portions may be made of different materials, which can allow the heatsink to be made of materials that can be manufactured thinner. The thinner fins can further improve thermal dissipation performance.

Total heat exchange element paper having excellent moisture resistance and gas barrier properties, comprising a substrate sheet and a moisture absorbent and colloidal silica both of which are adhered to the substrate sheet, wherein the substrate sheet contains natural pulp which has been beaten to a freeness specified in JIS P 8121-1:2012 of not lower than 80 SR and the colloidal silica is cationic colloidal silica.

A multi-effect woven fabric for energy harvesting and heat management includes a combination of a predetermined number of yarns woven to each other in a repeating pattern. The yarns include a first yarn for absorbing, storing, and releasing heat energy through a phase change, a second yarn for converting heat energy from a wearer's skin, the first yarn, and a third yarn into far infrared radiation energy and radiating the far infrared radiation energy to other yarns and to the wearer's skin, the third yarn for absorbing moisture from the wearer's skin and/or ambient environment and generating heat energy through an exothermic process, and a fourth yarn with a hydrophobic property. The multi-effect woven fabric maintains a uniform temperature on the wearer's skin by a combination of heat energy generation, heat energy harvesting, and radiation of heat energy.

Systems and methods are provided for protecting a temperature sensitive object. A system includes a temperature sensitive object and a thermal control material in thermal communication with the temperature sensitive object. The thermal control material has an emissivity that varies as a function of temperature, and includes a substrate comprising a first surface comprising one of a photonic crystal, a metamaterial, a metasurface, and a multilayer film, a solid state phase change material in contact with the surface, and a reflective thin film material at one of a second surface of the substrate, at a surface of the solid state phase change material, and on an opposite side of an optical cavity from the substrate.

A height-adjustable heat dissipation unit includes a main body, which has a top plate member, a bottom plate member, an extendable structure and a chamber. The extendable structure is a tapered structure located between and connected to the top and the bottom plate member, and consists of one or more folding sections. The chamber is provided on inner wall surfaces with a main body wick structure and is filled with a working fluid.

An apparatus includes a thermally conductive interface assembly including a first component associated with a first interface surface and a second component associated with a second interface surface. The apparatus also includes a shape memory alloy component coupled to the thermally conductive interface assembly and configured to move one or more components of the thermally conductive interface assembly between a first state and a second state based on a temperature of the shape memory alloy component. In the first state, the first interface surface is in physical contact with the second interface surface, and in the second state, a gap is defined between the first interface surface and the second interface surface.

The present invention relates to a condenser for condensing gasses. The condenser comprises: an inner tube (1) having a bore (3) therethrough; an outer tube (2) having a bore (8) therethrough and two ends, the inner tube (1) passing through the bore of the outer tube (2); and a seal (15, 16) at each end of the outer tube. The outer tube has exterior and interior fins and is sealed to the inner tube so as to define a sealed space (11) between the inner tube and the outer tube. The space (11) is adapted to contain a liquid in contact with the inner tube (1) and the outer tube (2). The invention further relates to a method of condensing a gas using the condenser, a process of making a chemical using the condenser and a kit adapted to be assembled into the condenser.
