The invention relates to a heat exchanger comprising a first free space (7) for a first fluid (3), a thermally conductive wall (11) which, at least locally, delimits said first free space (7), in such a way that an exchange of heat can occur between the first fluid and the thermally conductive wall (11) which is hollow and encloses a material (13) for storing thermal energy by accumulation of latent heat, by heat exchange with at least the first fluid. The first free space (7) is divided into at least two separated channels (7a, 7b) in which two streams of the first fluid (3) can circulate at the same time but separately, the thermally conductive wall (11) which encloses the thermal energy storage material (13) being interposed between the two channels (7a, 7b).

A system may include a turbine and a recuperative heat exchanger system. The recuperative heat exchanger system is configured to receive exhaust gases from the turbine. The recuperative heat exchanger system may include a precool section to cool the exhaust gases, a major heating section to receive the cooled the exhaust gases, and a minor heating section to receive the cooled the exhaust gases.

An intensified cassette-type heat dissipation module includes a heat sink, an amplifying loop heat pipe, a condensing block and an object of application. The heat sink is provided with an embedding space for disposing plural refrigeration chips and the condensing block. The heat sink utilizes the amplifying loop heat pipe to dissipate heat. A cold-surface loop heat pipe affixes itself to the condensing block to transmit a cold source to the object of application. The refrigeration chips transmit energy to the condensing block, and the cold-surface loop heat pipe supplies energy required by the object of application.

An active clearance control valve (ACC Valve) includes a valve housing with a thermal shield provided externally to said housing, wherein said valve housing and said thermal shield have been integrally formed as one component. This may be achieved using additive manufacturing methods. Cooling channels and/or ribs may also be provided on or in the thermal shield.

A heat exchange cell includes a casing, a heat exchanger in which a first heat transfer fluid flows, a feeding zone, and first and second collection chambers for a second heat transfer fluid. The casing can include rear, front, and peripheral side walls. The heat exchanger can be helically-shaped, mounted in the casing, and include at least one tubular duct for the flow of the first heat transfer fluid. The tubular duct can be coiled about a longitudinal axis and define a helix. The feeding zone of the second heat transfer fluid can be defined in the casing coaxially and internally with respect to the helix. The first chamber can be defined externally with respect to the heat exchanger by a radially outer wall thereof and the peripheral side wall. The second chamber can be at least partially delimited by at least one separating element.

A heat exchanger (1; 1*; 100) includes a bundle of tubes (8), each extending in a respective elongation direction (X1) and defining a flow path for a working fluid that extends in the elongation direction, wherein each tube (8) of the bundle of tubes can be supplied with a working fluid; a matrix (6) of thermally conductive material that houses the tubes (8) of the bundle and that is configured, in use, for promoting heat exchange between working fluids that run through corresponding tubes (8) of the bundle; and a shell (4) made of thermally insulating material arranged around the matrix (6), wherein: the matrix (6) is made up of a plurality of sections (10; 10*) arranged aligned in the elongation direction (X1) and alternated by thermal interruptions (12) that extending transversely to the elongation direction (X1).

A heat utilization system according to the invention includes: a sealed container into which a hydrogen-based gas is supplied; a heat generating structure that is accommodated in the sealed container and includes a heat generating element that is configured to generate heat by occluding and discharging hydrogen contained in the hydrogen-based gas; and a heat utilization device that utilizes, as a heat source, a heat medium heated by the heat of the heat generating element. The heat generating element includes a base made of a hydrogen storage metal, a hydrogen storage alloy, or a proton conductor, and a multilayer film provided on the base. The multilayer film has a first layer made of a hydrogen storage metal or a hydrogen storage alloy and having a thickness of less than 1000 nm and a second layer made of a hydrogen storage metal or a hydrogen storage alloy, which is different from that of the first layer, or ceramics and having a thickness of less than 1000 nm.

A dual path heat exchanger integrated as a single unit able to process fluid stream through a continuous, single-use high temperature short time process. The heat exchanger contains both a heating section and a cooling section in the same unit. In one embodiment, the heating and cooling sections (which may be formed separately for other uses) are formed as a plate and frame structure with a thermally conductive thin film or foil forming the physical barrier between the process stream flow path and the thermal medium (heating or cooling) flow path. The film/foil renders the heat exchanger suitable for single-use and/or to be disposable. A manifold, which also may be formed as a single unit, may be used to transfer fluid flow between the sections of the heat exchanger, and/or to transfer fluid into and out of the system formed by the heat exchanger and manifold.

An assembly having a structure provided with an interior volume in which is present for example at least one fluid capable of circulating in said volume and under the action of circulation means. Thermally insulating elements of VIP construction are arranged around a layer containing a PCM and extending around the peripheral wall that surrounds the volume. Protrusions fixed to the peripheral wall delimit spaces in which the thermally insulating elements are positioned. A sleeve extends around the protrusions and the insulating elements.

An air conditioning module including a thermo electric cell having a first side and a second side; an conditioning duct attached to the first side of the thermo electric cell; and an exhaust duct attached to the second side of the thermoelectric cell; wherein the conditioning duct receives and conditions air from a room, and the exhaust duct vents unwanted thermal energy.
