A heat exchange device includes a core and a housing. The core includes a first collecting part and a second collecting part, and a flat tube part is provided between the two. The flat tube part includes a first flat tube group and a second flat tube group. The first collecting part includes first and second collecting portions, and a separator is formed between the two. Each flat tube of the first flat tube group is communicated with the collecting cavity of the first collecting portion. The collecting cavity of the first collecting portion is communicated with the collecting cavity of the second collecting portion through the first flat tube group, the collecting cavity of the second collecting part, and the second flat tube group.

An apparatus for supplying and dissipating heat, for carrying out reactions and for mixing and dispersing flowing media in a housing with an internal diameter for a medium and comprising internal fittings made up of a bundle of tubes with an external diameter or made up of other elongate elements oriented parallel to the longitudinal axis of the housing is provided. The apparatus includes crosspieces or crosspiece layers installed crosswise between the elongate elements. The crosspieces are inclined in relation to the longitudinal axis of the housing and are not in contact. After axially successive crosspieces, or a length, the crosspieces are installed between the tubes and turned by preferably 90°. A heat-transfer medium can flow in a co-current or counter-current mode. This results in a mixer/heat exchanger or reactor with an extremely large heat-transfer capacity and almost plug flow.

A heat exchanger, comprising: a tube bundle having at least one tube for receiving a fluid medium, wherein the at least one tube is wound about a core tube which extends along a longitudinal axis, and a first tube section of the at least one tube rests against at least one web which extends along the tube core and at least one first bracket element for securing the first tube section to the at least one web, the at least one first bracket element having a lower face which faces the first tube section and rests against the first tube section. The invention additionally relates to a securing system and to a method.

A tube stay mounting assembly includes a press assembly having a housing and a top block configured to flatten fins on a first surface of a finned tube. A press arm is operable to move the top block vertically with respect to the housing. A bottom block is configured to flatten fins on a second surface of the finned tube when the press arm is rotated and moves the top block downwardly. A tube stay clamping assembly includes a clamping housing configured to receive a tube stay having a top, bottom, rear, and front walls, the tube stay being configured to receive a flattened portion of the finned tube. A clamping arm is connected by linking arms to a clamping block, the clamping block configured to engage and force the front wall into snap-fit engagement with the top wall of the tube stay.

A refrigeration, or thermal, energy storage system for storing refrigeration, or thermal, energy, comprising a body, closed and insulated, the body being configured to contain two fluids, respectively a Phase Change Material (PCM) type fluid and a secondary fluid, the two fluids being immiscible with each other and having different densities, so as to be stratified within the volume of the body; withdrawal means configured to draw the secondary fluid from the body, and to convey the same inside a heat exchanger configured to exchange frigories, or calories, with the secondary fluid; and distribution means configured to draw the secondary fluid from the heat exchanger, and distribute the secondary fluid into the PCM type fluid, so that the secondary fluid exchanges with the PCM type fluid frigories, or calories, absorbed in the heat exchanger, the secondary fluid having a solidification temperature substantially lower than that of the PCM type fluid.

The invention relates to a wound heat exchanger having a core tube extending along a longitudinal axis in an axial direction and having a tube bundle, which has a plurality of tubes for conducting a first fluid, wherein the tubes are wound about the core tube in a plurality of windings, the tubes being arranged in a radial direction perpendicular to the axial direction in a plurality of tube layers, adjacent windings of at least one tube layer having different axial distances in the axial direction and/or tube layers adjacent in the radial direction having different radial distances from each other in a cross-sectional plane perpendicular to the longitudinal axis. The invention further relates to a method for producing a wound heat exchanger and to a method for transferring heat between a first fluid and a second fluid by means of the heat exchanger.

A heat exchanger includes a sensor grid with sensor leads extending through tube restraints for heat exchange tubes in the heat exchanger. The tube restraint includes a body having a plurality of tube openings defined therein with each tube opening receiving one heat exchange tube of the set of heat exchange tubes therethrough. The body also includes a sensor lead opening defined therein to receive a sensor lead therethrough. Each tube opening has a larger dimension than the sensor lead opening. The sensor grid is installed during manufacture rather than in the field, allowing the sensor grid to be on outermost and inner sets of hea exchange tubes in the heat exchanger.
