Definitions

  • the invention relates to a heat exchanger, com ⁇ prising - several plate components joined together tightly and provided with orifices for flow, which components form at least one heat transfer unit,
  • Recuperators are divided into two generally known main types, i.e. tube heat exchangers and plate heat exchangers.
  • a tube heat ex- changer tubes As heat delivery surfaces of a tube heat ex- changer tubes are used, in which one medium is inside the tubes and another medium flows outside the tubes, inside a casing surrounding the tubes.
  • Advantages of the tube heat exchanger are a simple structure, a good resistance to pressure and temperature and a possibility of using standard parts at the manufac- ture.
  • drawbacks are bad heat transfer properties of the tube, whereby lots of tubes are needed for providing a sufficient heat power, which makes the device expensive and big.
  • standard tubes are thick-walled, which makes the device heavy.
  • the working life of the plate heat exchanger is short, since rubber ages rapidly under the influence of open air and looses its resilience at the same time, whereby the heat exchanger looses its pressure resistance, i.d. it begins to leak.
  • the straight end plates are very thick, which makes the device heavy, especially if the work ⁇ ing pressure is high or the size of the plate is big.
  • the object of the present invention is to pro ⁇ vide a totally new heat exchanger, which does not have the bad properties of the tube heat exchanger or the plate heat exchanger. This object is achieved by means of a heat exchanger according to the invention, which is characterized in that
  • each plate component is corrugated and each of them has only two orifices for flow functioning as connecting orifices for the primary flow and forming in the unit only two flow channels in the longitudi- nal direction of the unit for the primary flow, the inlet and outlet of which channels are arranged through the end plates,
  • the solution of the invention is based on the idea of replacing the tube systems of a tube exchang- er by a simplified plate heat exchanger designed in a new manner, which makes it possible to combine the good thermic properties of the plate heat exchanger and the simplicity of the tube exchanger.
  • the con- necting orifices of the plate components of the heat transfer unit are reduced by half, because only two of them are needed in each component; thus, the area of the heat delivery surface increases also when com ⁇ pared to the plate heat exchanger. It is also pos- sible to make the end plates thinner, for the end plates of the tube exchanger can be used.
  • the plate components are most preferably joined together by welding, whereby the weld joints form a necessary sealing and define together with the plate components the flow channels for the primary flow.
  • the heat exchanger can be made into a reli ⁇ able structure with a very long working life with re ⁇ spect to the resistance to pressure and temperature.
  • Figure 1 shows schematically a longitudinal cross-section of a heat exchanger according to the invention
  • Figure 2 the device of Figure 1 cut and seen from the end direction
  • Figures 3a-3d show manners of joining plate components of the heat exchanger according to the Figures 1 and 2, and Figure 4 shows another embodiment of xhe plate heat exchanger of the invention.
  • the heat exchanger shown in the Figures 1 to 3 comprises a heat transfer unit 1 formed of plate com- ponents la joined together tightly, a casing 2 sur ⁇ rounding this and end plates 3 shutting the ends of the casing 2.
  • the plate components la most preferably made of rolled thin plate with a thickness of 0,3 to 0,7 mm serve as heat delivery surfaces of the heat exchanger and they are corrugated or folded in shape.
  • Each plate component la has two connecting orifices 4 and 5 for the primary flow.
  • the connecting orifices 4 and 5 form two flow channels 6 and 7 in the longitudinal direction of the heat exchanger and the heat transfer unit 1, respectively, for the primary flow.
  • the first channel 6 serves as an inlet channel and the second channel 7 as an outlet channel.
  • For the prima ⁇ ry flow are arranged an inlet 8 and an outlet 9 in one of the end plates 3.
  • annular space 14 Between the casing 2 and the heat transfer unit there is an annular space 14, in which are pre- ferably arranged flow control plates 15 mainly in the longitudinal direction of the heat exchanger for the control of the secondary flow. Consequently, the sec ⁇ ondary flow is controlled by means of the flow con ⁇ trol plates 15 for instance transversely through the heat transfer unit 1.
  • the plate components la are most preferably joined together by welding (see Figures 3a and 3b). At the spaces between plates to be left open, i.e. at the flow channels 11 of the secondary flow, the join- ing has been carried out around the connecting ori ⁇ fices 4 and 5. These weld joints are indicated by reference numerals 16 and 17. On the other hand, those plate components la between which the trans ⁇ verse flow channels 10 for the primary flow are lo- cated have been welded together with a weld joint 18 situated close to the edges of the plate components la. The weld joints 16 to 18 have then been made such that they also constitute a necessary sealing. At the same time, the weld joints 16 to 18 also define to- gether with the plate components la the flow channels 6, 7 and 10 for the primary flow.
  • the weld joints 16 to 18 can also be replaced by rubber gaskets, whereby it is most preferable to use double gaskets 19 to 21 according to Figures 3c and 3d, which gaskets guarantee that the primary and secondary flows in no situation can get mixed with each other. If leakage flow occurs, it runs between the double gaskets 19 to 21 through orifices 22 and 23 of the plate components la into the next space between plates and further through an orifice (not shown) in the end plate out of the heat exchanger.
  • FIG 4 shows one embodiment of the heat ex ⁇ changer of the invention, in which two heat transfer units 1' and 1" joined together are arranged inside a common casing 2' and independent flows separated from each other run inside each of these units.
  • the heat ⁇ ing running inside the casing 2' and through the heat transfer units 1' and 1" can, for instance, heat the above two flows running in the heat transfer units.
  • the flow running inside the casing 2' can be con ⁇ trolled by means of spacing plates 15'.
  • the heat exchanger of the invention can vary within the scope of the en ⁇ closed claims.
  • the plate components and the casing can both be made of the same material or of different materials.
  • the casing for instance, can be made of plastic and the plate components of metal, or both the casing and the plate components of plas ⁇ tic, for example.
  • the total weight can be substanti ⁇ ally regulated by means of these' solutions.
  • the heat transfer unit and the casing can be e.g. rectangular in shape and the connection points can be located at the casing arbitrarily, if it is justified considering the flow/heating techni ⁇ ques. It is, moreover, possible to carry out a unit with no flow control unit at all. Such a use is for instance a coil for moving water in an oil vessel, in which the secondary flow functions at free circula ⁇ tion.

Abstract

L'échangeur thermique décrit comprend des surfaces de dégagement thermique (1a) et des canaux d'écoulement (6, 7, 10, 11) avec des entrées et des sorties (8, 9, 12, 13) pour les écoulements primaire et secondaire. Les surfaces de dégagement thermique sont conçues de façon à former au moins une unité de transfert de chaleur (1) constituée par des composants en forme de plaques ondulées (1a) qui sont assemblés entre eux de façon serrée et dans lesquels sont ménagés des orifices de liaison (4, 5) pour l'écoulement primaire, ces orifices formant deux canaux d'écoulement (6, 7) pour l'écoulement primaire, dans le sens de la longueur de l'échangeur thermique. Des espaces compris entre les plaques de l'unité (1), un sur deux comporte des canaux d'écoulement transversaux (10) pour l'écoulement primaire et des espaces ouverts qui sont proches de ces premiers espaces forment des canaux d'écoulement transversaux (11) pour l'écoulement secondaire. L'unité de transfert thermique (1) est en outre entourée par un logement (2) qui comporte une entrée (12) et une sortie (13) pour l'écoulement secondaire et qui est obturée à ses deux extrémités par des plaques terminales (3), dont au moins une comprend une entrée (8) et une sortie (9) pour l'écoulement primaire.
