Definitions

  • the present invention relates to a finned pack heat exchanger, including side stiffening and reinforcing section members.
  • the side stiffening and reinforcing section members are supported and held in their set positions by lateral guides applied to refrigerating, conditioning and heating apparatus.
  • the subject finned pack heat exchanger has been provided for overcoming the great drawbacks affecting prior available heat exchangers.
  • a fluid flows which, depending on the use of the heat exchanger, can comprise hot water, cool water or a vaporizing or condensing fluid, such as in the case of the so-called ventilated condensers.
  • Air is conventionally caused to pass through the mentioned fins.
  • the mentioned manifolds operate to evenly distribute the operating fluid through the pipes or tubes of the heat exchanger.
  • the frame is made of side and middle supporting plates, which are provided with calibrated holes therethrough the heat exchanger pipes pass.
  • Covering elements for the finned packs can be moreover provided.
  • the finned pack of conventional heat exchangers is essentially supported by the tubes or pipes passing through the side and middle plates of the frame.
  • the latter also operates to allow the heat exchanger to be assembled or mounted in a more complex apparatus, conventionally also provided with ventilating assemblies.
  • the mentioned apparatus are called air conditioners, air vaporizers, condensers, as ventilated and cooled by a liquid.
  • a very critical aspect of the above mentioned apparatus and, in particular, of the ventilated condensers, is the possibility of breaking of the pipes or tubes.
  • said ventilated condensers are also used for air conditioning purposes.
  • a novel finned pack heat exchanger has been designed, the construction of which comprises side stiffening section members and in which the finned pack is laterally suspended, thereby it is supported so as to fully prevent the tubes and side and middle plates of the frame from contacting one another.
  • the subject finned pack heat exchanger construction provides to use exchanger pipes or tubes arranged parallel to one another, as well as cross arranged fins having standard size and features conventionally characterizing heat exchangers for air conditioning, refrigerating and industrial applications.
  • This novel system is constructed by assembling on the side edges of the fins, in the tube direction, a plurality of specifically designed section members operating to stiffen the finned pack.
  • the main object of the present invention is to provide a strong bearing and assembling system for the mentioned types of heat exchangers.
  • Another object of the present invention is to provide reinforcing side section members also designed for allowing the finned pack to thermally expand and being coupled to the fins by an adhesive material or similar anchoring systems.
  • Another object of the present invention is to provide a construction including reinforcing section members, for finned pack heat exchangers, which are adapted to be suitably supported by other supporting and guiding section members, as affixed to side panels of refrigerating, conditioning and heating apparatus.
  • Yet another object of the present invention is to provide supporting section members having any desired shape and size to properly support the heat exchanger while allowing it to easily slide.
  • a finned pack heat exchanger characterized in that said finned pack heat exchanger comprises a plurality of parallel longitudinal tubes and cross fins having holes therein said pack forming tubes or pipes are housed.
  • the pipe or tube pack in particular, is stiffened by side reinforcing section member of C-cross section which bear on supporting side section members or other similar supporting and sliding systems, applied to the apparatus the heat exchanger is assembled to.
  • the finned pack heat exchanger which has been generally indicated by the reference number 1, is made starting from a plurality of longitudinal parallel pipes or tubes 3, therethrough a fluid is caused to flow, and a plurality of cooling cross fins 4, having a plurality of holes 18 therein said pack forming pipes or tubes 3 are engaged.
  • the tube pack in particular, is stiffened, according to one aspect of the present invention, by side reinforcing section members 9, bearing on side supporting section members 8 and guiding section members 7, applied to the side walls 14 of the apparatus 2 the subject construction 1 is assembled to.
  • the reinforcing and supporting section members 9 are coupled to the cross fins 4 by an adhesive material or other suitable anchoring means.
  • the mentioned side reinforcing and supporting section members 9 have a C-shape cross section.
  • the mentioned reinforcing and supporting section members 9 are provided with gaps or interruptions for allowing the tubes 3 to thermally expand and, accordingly, for allowing the thermal expansion of the several portions forming the finned pack, without imposing any mechanical stress on the tubes or pipes 3 forming the heat exchanger 1.
  • the heat exchanger 1 is assembled on the body of the apparatus 2 and, more specifically, on its ventilated condensers, so as to cause the C-shape reinforcement side section members 9 to bear on the supporting 8 and guiding 7 section members as preliminarily coupled to the side walls 14 of the panels forming the framework for holding a heat exchanger 1.
  • the side and frontal plates 14 and 15 of the heat exchanger 1 according to the invention providing a suitable mechanical strength to the apparatus 2 structures thereon they are assembled, are provided with openings 6' or holes 6 for allowing tubes 3 having a diameter larger than that of the latter to pass therethrough, so as to prevent any contacts of the tubes or pipes 3 and plates 15.
  • the subject heat exchanger 1 is made so that the tubes 3 of the heat exchanger and the other components of the apparatus do not contact one another.
  • said finned pack heat exchanger 1 is supported by the apparatus 2 to which it is applied at the side reinforcing section members 9 bearing on the side supporting section members 8 which are in turn applied to the side walls 14 in parallel to the laying direction of the tubes or pipes 3.
  • the subject finned pack heat exchanger 1 is moreover provided with holes 18 formed through the fins 4, which are delimited by upturned portions 5 defining the holes having the diameter of the pipes or tubes 3.
  • the L-shape side supporting 8 and guiding 7 section members are coupled to the side walls 14 of the apparatus to which the subject finned pack heat exchanger 1 is applied.
  • the C-shape reinforcing section member 9 is glued or made rigid in any other suitable manners to the subject finned pack heat exchanger, which will be free of sliding on the guiding 7 and supporting 8 section members, respectively.
  • Said section members 7 and 8 will both operate as guides in the case in which the apparatus is vertically installed.
