abstract |
In a first aspect, the invention provides a method for manufacturing a heat-exchanging element, the element comprising a tube structure and a plate structure, the method comprising the steps of: providing the tube structure and the plate structure, applying one or more portions of a solder paste, arranging the plate structure against and along the tube structure, at least at the level of the solder paste, and heating the solder paste according to a predetermined temperature range. In particular, the solder paste then has a viscosity of a minimum of 250 Pa-s and a maximum of 350 Pa-s, and is forced during this sorting through one or more openings in the plate structure. In further aspects, the invention further provides a method and device for manufacturing heat-exchanging elements, and a heat-exchanging element as such. |
