Definitions

  • the present invention relates to a thermal exchanging apparatus having a modular structure, as well as to the manufacturing method of this apparatus.
  • the field of the invention is that of boiler works, i.e. concerning the apparatuses used to obtain thermal exchange (climate control, heating, conditioning, etc.) in residential and industrial environments and for specific applications.
  • radiators for domestic heating, condensers, air conditioners and the like are obtained by welding of the components with which they are formed, such as the shell and tube and the corresponding supporting guards.
  • the industrial machining process of these products thus contemplates welding, brazing, grinding and sanding of the components of the radiator.
  • a further object of the present invention is to provide a method for manufacturing this thermal exchanging apparatus.
  • the one according to the invention offers the advantage of being manufactured in a rapid and simple manner, avoiding the formation of welding fumes, dust and with a considerable energy saving.
  • the exchanger further presents the advantage of being manufactured with a procedure in which the machining rejects and scraps are virtually eliminated, with a further positive effect on the direct and indirect manufacturing costs.
  • the invention further offers the advantage of allowing the use of standard basic components, so as to offer the required level of flexibility of the product's shapes and dimensions.
  • the invention makes possible the use in the thermal exchanging apparatus hereunder of components of any shape, according to a solution normally not feasible with the described known industrial welding and mechanical assembly processes.
  • the consequent freedom of design and shape offered by the invention allows to approach the product to the range of "household appliances" and interior furnishing and design. In industrial context, instead, it allows the use of many multimaterial and multicolour components without increasing the manufacturing process costs.
  • the apparatus of the invention unlike the traditional apparatuses, allows its components to be disassembled, so as to make possible the replacement of only the damaged parts and to recover the useable parts, thus promoting the operations of disposal and recycling of the materials used at the end of the product's life.
  • a further advantage of the invention is represented by the essential elimination of faulty parts, so as to no longer require additional machining, traditionally performed on non-compliant parts of the apparatus during manufacturing.
  • thermal exchanging apparatus a thermal exchanger in the example, is indicated as a whole by 1 in figure 1 .
  • This essentially consists of a series of elements 2 reciprocally coupled at pipe fittings 3.
  • Each element 2 is in turn formed by a tube bundle 4, joined to corresponding terminal parts, in turn formed by an upper head 5 and by a lower head 6.
  • the thermal exchanger of the invention display elements 2 arranged with vertical orientation and elements 7 with horizontal orientation, as well as upper 5, lower 6 and side 8, 9 heads provided with respective pipe fittings 10 and 11.
  • said upper 5 and lower 6 heads are formed by a cap 12, the latter provided with attachments 13 which reproduce the shape of the section of tubes 4.
  • These tubes are thus joined to attachments 13 by means of one stub pipe 14 for each tube.
  • the reciprocal coupling or connection between these components is obtained by partial insertion of the tubular body of the same one inside the other, the fixing between the parts thus coupled being finally obtained with the use of appropriate gluing resins.
  • the resins used are those of the Loctite® 600 series made by Loctite of the Henkel Group, possibly combined with appropriate cleaners and activators.
  • thermal exchanger in the case of plastic material components, preferably filled plastic materials, Loctite®..638 resin is used.
  • the thermal exchanger according to the invention may also be made with any other material adapted for the purpose and, however, assembleable by gluing the single components.
  • the assembly between the components of the apparatus of the invention is obtained by socket-type connection, contemplating the truncated cone shape of the direct coupling sections between attachment 13 of head 5,6,8,9 and tube 4.
  • socket-type coupling may obviously be obtained also with different shapes, not shown.
  • Element 2 shown in figure 9 is obtained by assembling, by gluing with resins, head 5 on tubes 4, after interposing attachments 13, the latter either integral with cap 12, or glued onto it.
  • This cap 12, which along with attachments 13 forms head 5, presents a seat consisting of a hole 18 which receives the corresponding pipe fitting 3, shown in better detail in figure 11 .
  • Such pipe fitting 3 consists of a male insert 15, a female insert 16 and a spacer 17.
  • male insert 15 is accommodated in its seat 18, prior to the formation of the head 5 or 6.
  • flange 19 of insert 15 is glued to the corresponding internal wall of cap 12, at the height of the mentioned seat 18, so as to maintain the necessarily sealing action.
  • connecting section 20 of the mentioned male insert 15, protruding outside cap 12 is intended to be fastened, by gluing, firstly inside spacer 17 and then in female insert 16, the latter in turn accommodated inside cap 12 of contiguous element 2.
  • male insert 15 is formed directly at the mentioned seat 18 of corresponding cap 12, by creating a flap of material of the corresponding wall of cap 12 itself, intended to act in the same manner as connection 20 of insert 15 itself.
  • an internal fold 21, possibly threaded, is contemplated at seat 18 of cap 12.
  • the coupling between elements 2 of the apparatus of the invention is obtained once again by using male insert 15 and a "T"-shaped pipe fitting 22.
  • connecting part 20 of insert 15 is specifically engaged by the mentioned fold 21, while flange 19 is fixed, by gluing, outside the corresponding wall of cap 12.
  • the mentioned pipe fitting 22 contemplates a fin 23 which engages fold 21 of cap 12 of the continuous element, and a flange 24 and a pipe fitting appendix 25 with corresponding parts 19, 20 of insert 15.
  • male insert 15 and pipe fitting 22 of the version in figure 13 are used once again, where though instead of internal fold 21, at seat 18 of cap 12, a connection ring 26 with insert 15 provided with an edge 27, positioned at the contour of the mentioned seat 18 is contemplated.
  • the same type of connection is obtained also on T-shaped pipe fitting 22, on the side of contiguous element 2.
