Definitions

  • the present invention relates to a composable heat exchanger, made starting from modular elements, as well as the method for making said heat exchanger.
  • these heat exchangers in their most usual form, are provided with a central portion defining the passage duct of one of the thermal exchange elements, which central portion is provided with fins for greatly increasing the useful thermal exchange surface, the thermal exchange being carried out through a second fluid element inpinging on the ouside of the mentioned duct.
  • the known heat exchangers as conventionally made, present however great drawbacks, since the thermal exchange elements thereof have a rather complex construction, mainly because of the provision of the fins,which are indispensable for increasing the thermal exchange surface.
  • Another drawback consists of the difficulty of making different size, and hence different thermal capacity,heat exchangers,depending on the speci fic application requirements: due to this reason it is presently necessary to suitably specifically design different size heat exchanging elements, depending on their uses.
  • the task of the present invention is to overcome the above mentioned drawbacks, by providing a modular element heat exchanger which can be easily made by quickly and simply assembling a plurality of modular elements so as to obtain the desired size.
  • Another object of the present invention is to provide a heat exchanger the single modular elements of which can be obtained by very simple and unexpensive mechanical operations and which may be assembled, in a very quick way, so as to provide the heat exchanger with the desired size.
  • Yet another object of the present invention is to provide a heat exchanger which may be easily constructed starting from easily commercially avail able elements and materials and which, moreover, is very reliable from the operation standpoint.
  • a composable heat exchanger characterized in that it comprises a plurality of modular elements, which may be stacked onto one another in order to form a thermal exchange column, each of said modular elements being provided with a base region and a middle portion therefrom a cylindrical body extends which is provided, on the bottom thereof, with throughgoing openings.
  • said cylindrical body may be coupled, at one end thereof, to the other end of the cylindrical bo dy of a like adjacent modular element, whilst said stacked cylindrical bodies form the duct of the thermal exchange column and said base regions form the related fins.
  • the composable heat exchanger which has been overally indicated at the reference number 1, comprises a plurality of modular elements 2 which may be stacked onto one another to form a thermal exchange column, having the desired size depending on the required thermal exchange capability.
  • a main feature of the present invention is that said modular elements 2 are made by very simple and unexpensive mechanical operations which, on the other hand, permit to construct a heat exchanger having very good efficiency characteristics.
  • each modular element is made starting from a plate-like element of a thermally conducting material such as, for example, a metal as stainless steel or copper, which is drawn so as to provide a peripheral base region 3, of flat shape, from the middle portion of which there extends a cylindrical body 4.
  • a thermally conducting material such as, for example, a metal as stainless steel or copper
  • the cylindrical body 4, at its bottom, is provided with a plurality of slots 5, which extend in parallel relationship with respect to one another, and may be made by cutting and bending the fins 6, having a given slant with respect to the axis of the body 4 and which diverge from the fluid path, inside the duct, which duct is obtained by stacking onto one another a plurality of modular elements.
  • the fins 6, which are arranged with a slanted orientation, will act to provide a turbolence in the fluid path, which fluid may be either in liquid form or gas form, so as to facilitate the thermal exchange.
  • the cylindrical body 4 On its periphery, the cylindrical body 4, at the end thereof therethrough the slots 5 are formed, is provided with a recessed region 7 which practically defines the insertion element, since this region may be inserted into the respective end of a like cylindrical body in order to stack a plurality of modular elements.
  • one of the thermal exchang e fluid consists of a liquid
  • This new process practically consists of applying, between the several modular elements, thin copper rods, indicated at 10 and then arranging the stacked modular elements in a vacuum oven.
  • said modular elements will be subjected to a high temperature adapted to melt the copper which, by capillarity, will deposit at the insertion region of the cylindrical bodies of the adjoining modular elements so as to provide a perfect welding connection which practically tightly closes the duct formed by stacking onto one another several modular elements.
  • Figs. 7 and 8 illustrate a variation in which a modular element 2 ⁇ has been provided having radially extending slots 6 ⁇
  • Fig. 9 illustrates yet another variation in which the modular element 2 ⁇ is provided with radially extending slots 6 ⁇ as well as a central hole 6′′′.
  • All of the disclosed modular elements may be coupled to one another, in different numbers, so as to obtain the desired heat exchanger, without the need of modifying the component elements thereof.
  • the composable modular element heat exchanger may be constructed in a very simple way and, moreover, the single modular elements may be made by very simple machining operation, by mechanically deforming a plate-like element, and hence with a series production of very low cost.
  • the single modular element may be assembled by means of a vacuum welding operation which is very safe and reliable.
  • the used materials provided that they are compatible to the intended use, as well as the specific size and shapes may be any, according to requirements.
