A cooling type housing (100) for housing a heating element (50) inside, including: an assembled metal housing (10); and a cooling flow path (30) provided at least on one surface (10A) of the metal housing (10), in which a heat medium flows, in which the cooling flow path (30) constitutes at least a part of the one surface (10A) of the metal housing (10).

The invention relates to a thermoplastic composition for a monolayer tube (T1, T2), and particularly to an air-conditioning circuit for a motor vehicle comprising tubes transporting a refrigerating fluid.

The composition comprises in weight fractions: more than 20% and up to 40% of a PA 6.10 and/or a PA 6.12, from 45% to less than 60% of a polyphthalamide having a Tg higher than 120° C. and selected from PA 6.I/6.T, PA 9.T, PA 10.T, PA 10.T/X, and from 10% to 20% of a compatibilizing system comprising a reaction product between (a) a polymer of olefin comprising an unsaturated epoxide and (b) a polymer of olefin comprising an unsaturated carboxylic acid, with weight ratio (a):(b) greater than 1.

A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

A tube sheet assembly for a heat exchanger is disclosed. The tube sheet assembly includes a plastic sheet having multiple tube-retention holes defined therein and a metal plate having multiple holes defined therein, each hole being substantially coaxial with a corresponding tube-retention hole of the plastic sheet. The metal plate is connected to the plastic sheet. The metal plate can be fabricated of, for example, steel or other metals. The plastic sheet can be fabricated of, for example, nylon, ultra-high-molecular-weight polyethylene, or polytetrafluoroethylene. Tubes can be disposed in the tube-retention holes of the plastic sheet and the holes of the metal plate. In an example, the tube-retention holes of the plastic sheet have a smaller diameter than the holes of the metal plate and the tubes contact the plastic sheet without contacting the metal plate.

The present invention relates to an encapsulated phase-change material (1) comprising a phase-change material (3) contained within a tube (5), said tube (5) being made of plastic and that it has a sealing weld (9) at least at one of its ends.

A fluid coil includes a tube bundle having a series of straight tubing runs and a series of return bends extending between and fluidically connecting ones of the straight tubing runs, an expansion header fluidically connected to at least some of the return bends and a polymeric material disposed in the expansion header. The polymeric material has an initial shape and is compressible to repeatedly expand and contract between a first volume in which water is present in the tube bundle and a second volume in which the water undergoes a phase change. Contraction of the polymeric material absorbs an increase in volume as the water undergoes the phase change to prevent stressing and rupture of the tube bundle and upon an opposite phase change, the polymeric material returns to its initial shape. The polymeric material can be a pressurizable bladder. A system and method to prevent the rupture of a tube bundle in a fluid coil are also disclosed.

Passive radiative cooling structures and apparatus manufactured with such cooling structures conserve energy needs. A flexible film transparent to visible light incorporates particles at a volume percentage larger than 25% so as to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent. Another film transparent to visible light is thin and flexible and configured to absorb and emit infrared radiation at wavelengths where Earth's atmosphere is transparent, wherein etchings or depositions are present on one or both surfaces. A high efficiency cooling structure has an emissive layer sandwiched between a waveguide layer and a thermal conductive layer. A solar cell panel is covered by a transparent passive radiative cooling film. A container housing an active cooling unit incorporates passive radiative cooling structures on one or more exterior surfaces.

An induction cooking appliance apparatus includes an induction coil, and a coil carrier configured to hold the induction coil and including a heat dissipation unit for dissipating heat emitted by the induction coil.
