摘要： A method for preventing formation of droplets in a heat exchanger, in which a second medium transfers heat to a first. The method is performed by a controller which receives different temperature values (T1, T2, T3) and a pressure (P) value to be used for calculating a boiling point temperature value (TB) and determining a first temperature difference (ΔT1) and a second temperature difference (ΔT2). Generating a flow control signal, for controlling the flow of the first medium into the heat exchanger, based on the first temperature difference (ΔT1), the second temperature difference (ΔT2) and the first temperature value T1 and sending the flow control signal to a regulator device for controlling the flow of the first medium in the heat exchanger.

摘要： An evaporator (1) for vaporizing a substance into its gaseous form, which comprises a cylindrical outer shell (2) and a plate pack (4) arranged inside the cylindrical shell in its lower part and a droplet separator (9) arranged above the plate pack. A recirculation of a substance to be vaporized is carried out by using flow guides (10a, 10b) arranged tightly between the plate pack and the outer shell and by an ejector pipe (13) arrangement comprising a collection pipe (11) arranged inside the outer shell.

摘要： In a method for producing a series of at least a first and a second plate-fin heat exchangers, several elongate fluid distribution tanks are installed on the matrix unit, each tank capping just some of the openings assigned to the first fluid and to the second fluid, each tank having its axis in the direction of stacking and each being connected to a pipe so that the number of openings assigned to the first fluid differs from the number of openings assigned to the first fluid, and for preference, the number of openings assigned to the second fluid differs from the number of openings assigned to the second fluid for the at least first and second exchangers of the series.

摘要： An object of the present invention is to provide a diffusion bonding heat exchanger with which it is possible to reduce a thermal stress that is generated due to heat exchange between fluids significantly different from each other in temperature even in a case where the number of stacked heat transfer plates is made large. A diffusion bonding heat exchanger (100) includes a core (1) in which a plurality of heat transfer plates (HP) are stacked and diffusion-bonded to each other. The core includes a plurality of flow path blocks (40) each of which is configured to include a plurality of flow path layers (30) and a partition wall layer (50) that divides the plurality of flow path blocks. A thickness (t3) of the partition wall layer in a stacking direction is larger than an interval (t2) between flow paths arranged in the stacking direction.

摘要： The invention relates to a method for manufacturing a brazed plate type heat exchanger comprising the following steps: a) stacking, with a clearance, a plurality of plates parallel to each other so as to define, between said plates, a plurality of passages suitable for the flow of at least one fluid, said passages being delimited by peripheral edges and at least one passage comprising at least one zone to be supported emerging towards the outside of the passage through at least one opening of a peripheral edge; b) arranging at least one support member in the zone to be supported; c) brazing the stack of plates comprising the support member; and d) removing the support member from the zone to be supported through the opening. According to the invention, the support member is deformable and, in step d), a traction force is exerted on the support member so as to cause a deformation in at least one part of the support member and a translation movement of the support member towards the outside of the passage.

摘要： A cold plate is provided and includes: a housing disposed with a chamber; a base combined with the housing to form a working space separated from the chamber but connected with the chamber through an interconnecting structure to allow a working medium to flow within the chamber and the working space; a heat transfer structure disposed on the inner side of the base; and a pump disposed within the working space to drive the working medium in the working space. As such, the cold plate can provide better heat dissipation performance.

摘要： An air to air heat exchanger is provided including a core having a plurality of alternately stacked first layers and second layers. Each first layer includes a plurality of first modules having corrugated fins that define a plurality of first fluid flow paths. The first modules are aligned to fluidly couple the first fluid flow paths. Each second layer includes at least one second module having corrugated fins that define a plurality of second fluid flow paths. At least one second layer includes a third module having a plurality of corrugated fins that define a plurality of third fluid flow paths. The third module is arranged such that the third fluid flow paths are parallel to the second fluid flow paths. A number of corrugated fins formed in the third module is less than a number of corrugated fins formed in the second module.

摘要： A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

摘要： An air fin for a heat exchanger has air channels defined by corrugations, the corrugations having generally planar flanks joined by alternating crests and troughs. Perforations extend through portions of at least some of the flanks and are aligned within two spaced apart planes. A rectangular aperture extends through at least two consecutive ones of the corrugations, and is bounded by the two planes. A method of making the air fin includes forming perforations into a continuous strip of metal sheet at regular intervals, corrugating the strip to form crests and troughs between the perforations, and punching out a portion of the strip at regular intervals. The punching out includes shearing webs between the perforations, and results in the formation of the rectangular aperture.
