摘要： The invention relates to a method and a device for improving heat transfer in a circular plate heat exchanger (1), as well as a heat transfer plate to be used therein. The invention is based on changing the flow conditions in the radial direction in such a way that the heat transfer remains even. The ridges between the grooves of the heat transfer plates (10) may be, in their shape, evolvent graphs or the like.

摘要： The present invention refers to a plate heat exchanger for at least two heat exchanging fluids, which heat exchanger is permanently joined and comprises at least one core of plates with a plurality of heat exchanging plates (2) and at least two end plates (3, 4), the heat exchanging plates (2) creating plate interspaces between each other. Each one of the heat exchanging plates (2) is equipped with one or several corrugations and at least four port holes (9, 10) being parts in an inlet channel (11) and an outlet channel (12) through the core of plates for each one of the fluids. The inlet channels (11) and the outlet channels (12) for a first and a second fluid respectively are in fluid communication with a first (13) and a second (14) set of plate interspaces respectively. The heat exchanging plates (2) have outer edges of a similar design and on each other bearing heat exchanging plates (2) in at least each one of the plate interspaces being parts of the said first set of plate interspaces (13) are brazed together in their outer edges, around at least two port holes (9) as well as in preferably all of those points upon the heat exchanging plates (2) where the respective corrugations bear on each other while on each other bearing heat exchanging plates (2) in at least each one of the plate interspaces being part of the said second set of plate interspaces (14) are brazed together in their outer edges and around at least two port holes (10) only.

摘要： A process and apparatus for indirectly exchanging heat with narrow channels in a heat exchange type channel reaction zone uses plates (17) containing partially perforated sections (16) to simplify or eliminate the use of manifolds to distribute and collect different fluids to the various channels. The invention simplifies the operation by directly communicating adjacent channels across sections of perforations located at one end or the other of the channels. The arrangement of this invention provides the advantage of more compact heat exchanging reactor arrangements. The arrangement of the invention can also simplify the use of a single manifold arrangement at one end of the channels to facilitate catalyst unloading and catalyst replacement in the reaction channels.

摘要： A heat exchanger 6 has two inlets 63 and 64 and two outlets 65 and 66 for two counterflow air paths 7 and 8 through a stack plates 70. The plates 70 are vacuum-formed, each having a section 71 with zigzag walls 72 forming multiple flow channels 73 between adjacent plates. The edges of the plates have walls 90, 90' that nest with one another and are retained and sealed between ribs 95 on two side plates 14 and 15. Four grilles 16 to 19 at the inlets and outlets have bars 97 with recesses 99 retaining the edges of pairs of plates 70, the bars being separated by spaces 98 allowing air to flow between adjacent pairs of plates and into or out of the air paths 7 and 8.

摘要： Der Plattenwärmeübertrager besteht aus einem Stapel (1) bekannter Wärmeübertragungsplatten, dem ein zweiter Stapel (4) Wärmeübertragungsplatten nachgeordnet ist, die sich vom ersten Stapel (1) dadurch unterscheiden, daß sie auf der Brauchwasserseite (7) größere Profilierungen und damit Fließspalte aufweisen als auf der Heizwasserseite (8). Die beiden Stapel (1,4) werden von zwei verstärkten Endplatten (2,3) eingeschlossen, von denen die am ersten Stapel die Anschlüsse für Heizwasservor- und -rücklauf und Kaltwasserzu- und Warmwasserablauf trägt und an der anderen Endplatte (3) ein oder mehrere Temperaturmeßfühler (14) angeordnet sind. Der Plattenwärmeübertrager wird von den Medien Heiz- und Brauchwasser bei geöffneten Ventilen im Gegenstrom durchflossen. Um die kompakte Bauform bekannter Plattenwärmeübertrager beizubehalten, sieht eine Ausführungsform vor, die Wärmeübertragungsplatten grundsätzlich mit sechs Durchbrüchen (9) auf Kegelstümpfen zu versehen, die in den Eckbereichen zu je drei an den Längsseiten einer Platte angeordnet und wie die Profilierungen zur einen oder anderen Seite einer Platte (13) eingeprägt sind.

摘要： A method of heat exchange uses a non-azeotropic mixture of refrigerants in plate heat exchangers (4,6,) which accommodate variations in the relative proportions of liquid and vapour refrigerant, allowing the refrigerant in the two phases to main in equilibrium throughout the flow path through the heat exchanger (4, 6,). The configuration of the channel for the refrigerant through the heat exchanger (4, 6,) is arranged so that the resistance to the flow of refrigerant is greater towards one end than towards the other end. This can be achieved by one or more of the plates having a surface profile (14) which is configures so that the resistance to flow of heat exchange fluid along the channel is greater in one region (18, 20) along the length of the channel than in another region (16, 22).
