Definitions

  • the present invention relates to a method of producing a multicolumn radiator.
  • the present invention also relates to a multicolumn radiator produced using such a method.
  • Multicolumn radiators comprise two opposite heads connected by a number of columns.
  • Each head comprises a hollow central body, from which a number of pipes originate, one for each column, and is formed in two flash-welded parts.
  • the method currently used to produce multicolumn radiators of the above type comprises the steps of:
  • a multicolumn radiator defined by two metal heads, each having a hollow central body from which originate a number of pipes, and by a number of metal columns, each connected at one end to a respective said pipe of a first said head, and at the opposite end to a respective said pipe of a second said head; the radiator being characterized in that an inner recess defining a socket is formed on the ends of said pipes, and an outer recess defining a plug is formed on the free ends of said columns, or vice versa; said columns being fitted to the respective said pipes by inserting said plug inside the corresponding said socket.
  • Number 1 in Figures 1 and 2 indicates a multicolumn radiator comprising two (respectively, top and bottom) heads 2 made of metal, preferably steel; and a number of parallel vertical columns 3 hydraulically connecting heads 2 and also made of metal, preferably steel.
  • head 2 comprises a hollow central body 4 from which originate a number of pipes 5 (in the example embodiment shown, three pipes: two lateral and one central), the free ends 6 of which are parallel to one another for connection to corresponding free ends of columns 3.
  • the free ends 6 of pipes 5 have a reduction in inside diameter to define a recess or socket 8, and an annular shoulder 11 between socket 8 and the rest of pipe 5.
  • column 3 is cylindrical, and its free end has a portion 7 whose outside diameter is reduced to define a plug, and an outer annular shoulder 12 between portion 7 and the rest of column 3.
  • Portion 7 of each column 3 is inserted inside corresponding socket 8, so that the free edge of portion 7 rests on shoulder 11, and the free edge of pipe 5 rests on shoulder 12; for which purpose, portion 7 is the same length as socket 8.
  • head 2 is formed in two parts 2a, 2b welded to each other.
  • the method of producing multicolumn radiator 1 comprises:
  • Welding at the eighth step may be performed in various ways, or as shown in Figure 1 , i.e. by means of a copper alloy ring 14 fitted to portion 7 before this is inserted inside socket 8.
  • the whole multicolumn radiator 1 is placed inside a furnace at a temperature of close to 1100 °C to melt ring 14 and so braze portion 7 to socket 8.
  • a method is provided in which head 2 is laser welded, which is cleaner and cheaper than flash welding, and involves no finish work.
  • Columns 3 can be furnace-brazed to head 2, which is also cleaner, cheaper, and involves no finish work.
  • the plug and socket joint between columns 3 and pipes 5 provides for more effective welding of the columns to the pipes, by not being a butt weld, as in currently marketed radiators. Welding of columns 3 to pipes 5 is in no way compromised, even if columns 3 are not cut exactly to the right size.
  • the method described may be automated, thus reducing the manufacturing cost of multicolumn radiator 1.
