The present invention relates to a thermal battery having an enclosure (2) containing a bundle (3) comprising tubes (3) of encapsulated phase change material, the bundle (3) being formed by a stack of banks of tubes (3), said banks comprising tubes (3) placed parallel to one another and being connected by bracing and supporting bars (5), said bars (5) comprising, on at least one of their faces, individual housings separated from one another by a lateral wall, each housing being capable of receiving one tube (3).

The present disclosure describes a heat exchanger of a motor vehicle that is supplied with a cooling air mass flow that changes depending on a travelling speed of the motor vehicle. The heat exchanger includes a heat exchanger block with a plurality of flat tubes that are each received on a longitudinal end side in an associated passage opening of a tube sheet and provide a coolant path. A tank is connected to the tube sheet and defines a coolant header. An additional element is arranged on an outer edge or on an outer marginal region of the tube sheet. The additional element is structured and arranged to provide an at least partial covering of the tube sheet relative to an inflow side, e.g., relative to the cooling air mass flow.

The invention relates to a device for heat exchange, in particular in a refrigerant circuit, with at least one first flow path and at least one second flow path, which, in a cross section perpendicular to a longitudinal direction of the device, are disposed coaxially with respect to one another, and each of which comprises at least one flow channel. The device is realized of a synthetic material.

A pipe-within-a-pipe and method of use are provided. The pipe-within-a-pipe comprises a first tube overlaying a second tube. The first tube and the second tube have different structures in some respect.

A gearbox and a method for additively manufacturing the gearbox are provided. The gearbox includes a housing having an integral heat exchanger additively manufactured within the housing. The heat exchanger includes a plurality of heat exchange passageways for transferring heat between two or more fluids. The heat exchanger is defined at any suitable location or locations within the housing, for example, within voids defined between the walls of the housing and components housed within housing, such as driveshafts, gears, bearings, etc.

A method for operating a heat exchange system is provided. The heat exchange system includes at least one heat exchange chamber with heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber, wherein the heat exchange chamber boundaries comprise at least one first opening for guiding in an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one second opening for guiding out an outflow of the heat transfer fluid out of the heat exchange chamber interior, at least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

A heat exchanger that comprises a plurality of small channels that are arranged around a cross-sectional perimeter such that the sides of the small channels are touching to create bigger channels running parallel to the small channels. To this end, embodiments of the present invention have a heat exchanger matrix where the structure of the large channels is entirely comprised by the structure of the smaller channels resulting in a more compact, more efficient heat exchanger.

A heat exchanger includes a metal tube and a composite polymer fin in thermal contact with the metal tube. The fin is formed of a polymer and a thermally conductive filler such that the fin has a thermal conductivity greater than or equal to 0.5 Watts per meter Kelvin.

A heat exchanger includes a plurality of heat transfer tubes extending in a first direction and aligned in a second direction intersecting with the first direction, and a plurality of fins disposed in the first direction. The fins each include a plurality of fin main bodies aligned in the second direction, and a bridging portion connecting two adjacent ones of the fin main bodies. At least one of the fin main bodies is provided with a through hole next to the bridging portion in the second direction.

A turbine engine heat exchanger for exchanging heat between a first fluid and a second fluid includes a reference axis, a network of tubular meshes having a plurality of meshes each of which is formed, successively in a reference direction, of at least two curvilinear branches, called anterior branches, of a junction where the two anterior branches meet, and of at least two curvilinear branches, called posterior branches, diverging from the junction, wherein the meshes are stacked in staggered rows.
