  • thermal solar collectors can e.g. be based on the principle of letting the sun irradiate a dedicated surface in order to be absorbed by and heat that surface and thereafter transferring the heat from that surface to a fluid medium, facilitating transport of the heat to a desired location.

Due to the instability of the skeletal tubing structure the work of correctly positioning the skeletal tubing structure on the homogeneous absorber plate is usually quite cumbersome and time consuming. The instability in combination with residual stress in the skeletal tubing structure also makes it virtually impossible to achieve a close to one hundred percent contact between the tubing and the homogeneous absorber plate, which of course has a negative effect on the heat transfer capability of the heat exchangers manufactured in accordance with this known method.
  • One object of the invention is to provide a method for manufacturing a heat- exchanger, and in particular a heat-exchanger suitable for energy transfer between a plate and a fluid circuit, the method providing for eliminating or reducing one or more of the problems described above.

  • the handling system 3 is arranged to take one sheet metal plate 2 from the storage 1 and transfer it to an alignment unit 4, where the sheet metal plate 2 will be released and positioned in a pre-determined well defined position. Once the sheet metal plate 2 has taken the pre-determined well defined position, the handling system 3 will once again take the sheet metal plate 2 and transfer it to a plane working table 5. Due to the alignment step, exact positioning on the plane working table 5 is greatly facilitated. The sheet metal plate 2 will thereafter be fixed in a working position on the plane working table 5. The sheet metal plate 2 is preferable fixed to the plane working table 5 using vacuum suction, whereby the sheet metal plate 2 is brought into close contact with the plane working table 5, thus providing an essentially plane working surface on the sheet metal plate 2.
  • a predetermined length of continuous metal tubing 6 is prepared in a sequence of steps which includes, straightening the metal tubing 6, cutting the metal tubing 6 to the predetermined length required for the finalized product and winding the predetermined length of metal tubing upon a spool 7.

  • the tubing application unit 8 is arranged for successively applying the length of metal tubing 6 to the sheet metal plate 2.

  • a truing device e.g. consisting of a number of rolls 11.

  • the tubing 6 brought into close contact with the sheet metal plate 2 is then instantaneously affixed to the sheet metal plate 2.
  • affixing is effected through welding the metal tubing 6 to the sheet metal plate 2.
  • Laser welding is the preferred method of joining. Laser welding is particularly suited for the production in large volumes of the full plate absorber heat exchanger.
  • Welds 13 are suitably provided at both sides of the tubing 6 simultaneously during the welding operation. As the tubing 6 only needs to be brought into close contact with the sheet metal plate 2 at the weld point itself, the entire complex of tolerance problems is restricted to one point.

  • the thermal energy will be transferred to a fluid medium circulating in the tubing 6 and utilized for transporting the thermal energy to a different location. It will be obvious for the person skilled in the art that the same applies in the inverse direction, i.e. where the thermal energy of a fluid medium circulating in the tubing 6 is transferred to the tubing 6 and via the welds 13 to a plate 2 arranged to emit thermal energy to its surroundings.

  • a reactive process is used to produce a CERMET multi-layer coating with a graded refractive index, where very small metallic particles are dispersed in an amorphous dielectric matrix. The metal content is decreasing to the upper layers. Absorption is achieved by scattering effects at the metallic particles and the surrounding dielectric matrix.
  • multi-layer thin films use interference effects between semi-transparent layers to trap energy. Therefore an antireflection coating is applied on the surface of the layer stack, which also has the function of a protective film.
  • a special metallic coating is applied to the top of the substrate as a barrier layer to prevent corrosion of the substrate and diffusion of the substrate material into the upper layers, which enhances the durability of the coating drastically.
