Definitions

  • the subject of the invention is a plate heat exchanger, as well as a heat exchanger heat comprising at least one of these plates.
  • Heat exchangers are commonly used in several technical fields, such as transport, air conditioning, heat or batteries fuel. Many families also exist if we consider their structure, or the way in which fluid transport channels are built and willing.
  • the heat exchangers of which is part the invention include plates in which the Fluid transport channels are dug.
  • Such a structure offers the benefits of being compact while having good mechanical strength, especially with regard to high pressure fluids.
  • US 6 467 535 B1 where the plates include an outer envelope circumscribing a volume as partitions, a room with the envelope, divide into channels of flow two fluids.
  • Such plates can be manufactured in one piece by an extrusion process which, together with a sufficient thickness of the envelope and partitions, provides the desired resistance.
  • the invention relates firstly to a heat exchanger plate of particular shape and being easily adapted to connections by simple means.
  • the plate Heat exchanger includes an envelope exterior and partitions dividing a volume circumscribed by the envelope in channels, characterized what the envelope has reliefs, reliefs and the canals extending in the same direction longitudinal, a first category of canals extends into the reliefs, and the reliefs and the envelope are notched on a part in the longitudinal direction by opening the channels of the first category.
  • the reliefs can be established by two opposite sides of the envelope.
  • the heat exchanger comprises at least one of these plates in a stack, as well as a frame surrounding the stack and inlet ducts and fluid outlet through the frame and communicating to the channels, and it is remarkable in this that the ducts comprise on the one hand ducts communicating to the channels of the first category and extending from a first side of the frame, and secondly conduits communicating to a second category of channels (separated from the first by the partitions and carrying the other fluid) and extending from one second side of the frame that is different from the first.
  • the frame has four sides in rectangle, of which the first side and the second side cited, which are perpendicular to each other; both last sides, or any of them, can understand other fluid inlet and outlet ducts or connecting ducts between two plates.
  • the frame can also be simply made up of two independent parts at the ends of the ducts.
  • the lateral sealing of plates is made by assembling the reliefs lateral ends thereof.
  • the fundamental advantage of the invention is that the inlet and outlet ducts of two fluids are not intertwined or adjacent, but separate, the ducts leading to the channels extending into the reliefs being placed on one side of the plate, and the ducts leading to the other channels being placed on a longitudinal end side of the plate.
  • Channels in both categories can take different forms but it is advantageous that at least those of the first category have a oblong section, those of the second category having a section of more regular shape.
  • the exchange surface is increased if the channels have delimiting surfaces that are grooved in the longitudinal direction.
  • the plates are advantageously constructed by extrusion.
  • a heat exchanger plate compliant to the invention presents the section illustrated in FIG. 1, with an outer envelope 1 comprising 2 periodic reliefs projecting on two sides main 3 and 4 and opposite of this plate 5 and which extend in a longitudinal direction; the plaque 5 still includes partitions 6 extending from one side 3 to the other 4 under the reliefs 2, and also extending in the longitudinal direction.
  • These partitions 6 delimit channels 7 and 8, including those of a first category 7 extend under the reliefs 2 and in them, and those of a second category 8 extend between the reliefs 2 alternating with the precedents.
  • the first category channels 7 have a section substantially rectangular or oblong, and those second category 8 a section of more dimension regular.
  • Figure 2 illustrates by arrows A a fluid introduced on the plate 5 flows, by the notch 10 thus formed, in all first category channels 7, and also, on the second category channels 8, in channels of third category 9 extending between the reliefs 2.
  • One of the heat exchange fluids will follow actually these paths and the other will flow into the second category 8 channels according to the B arrows.
  • Notch 10 does not reach the second channels category 8, the fluids remain separate.
  • Channels 7 and 8 are shown substantially rectangular; other sections would be possible, as shown in Figure 3 and 4 illustrating first-class channels 7 elliptical and second category channels 8 respectively circular and elliptical; another type of development is that of Figure 5, which shows that channels 7 and 8 may have delimiting walls provided with micro-grooves 11 longitudinal lines giving them a serrated section increases the heat exchange surface between fluids. This provision will therefore be adopted before any on the sidewalls, which are the faces of partitions 6.
  • Figures 6 and 7 show a stack of plates 5, reliefs 2 of plates 5 stacked being in mutual support and closing the sections third category channels 9.
  • the interchange may be completed by a 12 frame assembled around the stack of plates 5 (which also includes two end plates, solid, not shown).
  • the frame 12 has four sides in a rectangle, and adjusts around the plates 5 by connecting to the channels 7 and 8. It is composed of elementary frames 15 of height at least equal to the plates 5, which they surround respectively and that are stacked like them.
  • the channels 8 of the second category are released by a machining beyond the notch 10 and fit into slots 40 machined in a first side 14 frames elementary 15.
  • a second side 16 of the frames elementary 15, adjacent to the previous, is pierced of orifices 41 opposite the notch 10. It will be noted that heat exchange is done from all sides channels 8 of the second category, to channels 7 and 9 of first and third category who surround it almost completely, and so it is very Well.
  • the tightness and cohesion of the exchanger of heat are provided by solders or collages 42 between the elementary frames 15.
  • the seal can also be made by welding in peripheral. The addition of seals is not needed elsewhere.
  • the whole is completed by distributors like the one in Figure 8.
  • the first side 14 receives an outlet distributor 18 of the second fluid and makes the second channels communicate category 8 with an outlet duct 19.
  • the second side 16 of the frame 12 receives a third distributor 23, which is an inlet distributor of the first fluid and communicates an inlet duct 24 to the orifices 41, at nicks 10 and at the channels of first and third category 7 and 9.
  • a fourth side 25 of the frame 12 receives an outlet distributor 26 of the first fluid provided with a conduit 27; this distributor 26 is at the longitudinal end opposite the distributor 23 previous stacking plates 5; distributors 23 and 26, and their connections and communications, are similar.
  • This device allows a flow to countercurrent in the heat exchanger.
  • a co-current flow configuration is also possible.
  • the distributors 18 and 23 are replaced by distributors 28 and 29 each having a conduit 30 or 31 and an outlet duct 32 or 33 with each communicates to a respective portion of the distributor and to a respective group of plates 5 and channels.
  • the other distributors 21 and 26 are replaced by boxes 34 and 35 allowing blind the passage of the respective fluid from one of the groups of plates 5 and channels to the other group.
  • the plates 5 can be constructed by an extrusion process using a material suitable, metallic or polymer, which gives a uniform unitary structure, then simple machining is accomplished to achieve the 10. It is possible to leave stops 36 to limit the depression of the plates 5 in the longitudinal ends of the frame. also mention the possibility, represented in Figure 10, to build the ends of the plates 5 in cross direction with shapes 37 and 38, to allow an assembly by abutment giving a resultant plaque more large.
  • a frame 12 surrounding construction completely the plates 5 is not necessary for build a heat exchanger. It is possible to use end pieces, placed only at the longitudinal ends of the plates. As in the previous realization, it would be possible to stack and to assemble pieces having the same height as the plates 5.
  • One of these pieces, comb-shaped, is shown in Figure 11 to reference 50. It is consisting of a lower reach 43 and teeth 44 se standing on it. Channels 8 of the second category fit again in slots 45, similar to crenals 40, separating the teeth 44.
  • the plate 5 is held in place by the lower reach 43 of a another end piece 50 that we put on the previous and who will receive another plate 5.
  • FIG. 12 An end piece 51 in the form of a plate gap, through which the ends of the second category channels 8 of all stacking plates 5, is illustrated in Figure 12.
  • This plate gap 51 is of unitary structure from the beginning.
  • Distributors similar to the previous ones can communicate to channels 7 and 9 of first and third category, even if the lateral sides of the stack of plates 5 are not coated.
  • the junctions of the plates 5 are soldered or glued, no sealing material not required.
  • the invention can be applied to Channels with a hydraulic diameter of about 0.5 mm, with a low manufacturing cost.
