Definitions

  • the invention provides a method for manufacturing a hollow panel through which heat transfer medium can flow, with at least one inlet and at least one outlet for the heat transfer medium, which method comprises the following steps, to be performed in suitable sequence, of:
  • the invention also provides a method for manufacturing a hollow panel through which heat transfer medium can flow, with at least one inlet and at least one outlet for the heat transfer medium, which method comprises the following steps, to be performed in suitable sequence, of:
  • step (b) is performed by seam-welding or laser welding.
  • step (c) use can be made of laser welding or resistance welding.
  • the method according to the invention can preferably be embodied such that substantially linear or annular, for instance circular, oval or polygonal weld zones are formed.
  • step (d) is performed by arranging the or each hole at an end of a strip-like zone, and step (g) is performed such that the access opening is embodied by performing step (g) such that an opening replaces the access opening.
  • a variant is generally recommended in which a connection for medium under pressure is arranged on the access opening after step (d).
  • the deformation pressure is in the order of magnitude of 400 bar.
  • provisions are necessary for transferring this pressure safely and without problem to the interior of the panel for forming.
  • For the hydraulic deformation use is preferably made of liquid such as water. In the case of calamity, for instance a rapid-action coupling coming loose, the pressure then immediately drops to safe values, other than in the case of a gas under pressure.
  • the method according to the invention comprises a step (l) of performing step (k) by performing step (c) such that a second strip-like zone is kept free of weld zones, and also performing steps (g), (h), (i) and (j) for this second strip-like zone.
  • the method can advantageously comprise (m) of placing the assembly of the two plates in the mould cavity of a mould prior to step (f), wherein the shape of the mould cavity corresponds with the external shape of the panel for manufacture.
  • the deforming process can hereby be performed with good accuracy in controlled manner such that the pipe fits more or less tightly in the elongate cavity in the panel.
  • the invention further relates to a hollow panel through which heat transfer medium can flow, manufactured with the method according to the invention, with at least one outlet and at least one inlet for the heat transfer medium, which panel comprises:
  • the invention relates to such a panel, wherein respectively the outlet or inlet is embodied in the same manner as said respective inlet or outlet.
  • a perforation is arranged in one of the two plates 3, 4 or in both plates (on an edge thereof), whereby the contact surface between the two plates becomes accessible for medium under pressure.
  • a connection can optionally be temporarily connected to this access opening, for instance a pipe welded thereon.
  • Medium under pressure in particular a liquid such as water, is thus supplied via the access opening under high pressure (for instance in the order of 400 bar), whereby, likewise according to the prior art, the parts of plates 3, 4 not welded together move apart and a hollow panel is thus created.
  • Fig. 4 shows the thus obtained situation, in which the access opening is not drawn or is already closed again.
  • the wave-shaped lines which connect the annular weld zones to each other, not being the weld zones and weld seams, show the hydraulic deformation. It will be apparent that the strip-like zone 7 free of weld zones is substantially "inflated", or hydraulically deformed. In order to keep particularly this plastic deformation under control, with a view to the subsequent processes to be described hereinbelow, this plastic deformation can advantageously take place, likewise as according to the prior art, in a mould with a mould cavity having a shape corresponding with that of the hollow panel to be finally obtained.
  • Fig. 5 shows that, according to the invention, openings 30, 31 are formed in the area of strip-like zone 7 at the ends of the centre line 19 thereof by grinding, drilling, milling or other suitable process. It will be apparent from the figure that an elongate cavity accessible from outside is hereby created. With a correct dimensioning, in particular making use of the above stated mould, this cavity can be dimensioned such that tube 2 fits more or less tightly therein.
  • Fig. 6 shows that tube 2 is inserted in the above described manner.
  • Fig. 7 shows from the top that tube 2 is connected to upper plate 4 in the area of centre line 19 along a weld seam 12 by means of a welding operation. On the underside the tube is connected to lower plate 3 in the same manner by a weld seam.
  • Fig. 8 shows that tube 2 is connected to edges 13, 14 of openings 30, 31 by means of welding.
  • the thus obtained panel 15 comprises two hollow panel parts 9, 10 which are mutually separated in medium-tight and pressure-resistant manner by tube 2. Medium can flow into or flow out of panel parts 9, 10 via perforations 17 in tube 2.
  • Fig. 9 shows a panel 20 which is manufactured using the same method steps as panel 15.
  • panel 20 comprises three feed/discharge tubes 2, 21, 22.
