Definitions

  • Present invention concerns a method of connecting absorption plate with tube register of a thermal solar collector.
  • An absorber made by soldering has a disadvantage that both absorber and tube register must be made of the same material, the joint has relatively small contact surface and, as a consequence, it exhibits relatively high resistance against heat transfer from the absorber to heat transferring medium flowing in the tube register.
  • a further disadvantage consists in that at increasing stagnant temperatures of high performance modern collectors the danger of solder softening and separating the absorber from the tubes increases, or possibly, that fusing agents may release gases which might condense in the form of stains at the inner side of the transparent collector cover.
  • An absorber produced by welding using ultrasound, has a disadvantage that similarly as in the above case it allows connecting of the same materials only and, moreover, it exhibits even higher resistance for the heat transfer from the absorber into the tube.
  • a further disadvantage consists in that during welding the selective conversion layer at the weld site is mechanically destructed, thus deteriorating the performance parameters and appearance of the absorber.
  • An absorber produced by welding using laser, has a disadvantage that the resistance against heat transfer from the absorber into the tube register is the highest from among all above mentioned examples.
  • a further disadvantage consists in that if the absorber and the tube register are made of different materials, the joint durability may be considerably limited as a consequence of different heat dilatations.
  • the aim of the present invention is a method of production of an absorber exhibiting small resistance against heat transfer, wherein the absorption plate and the tube register may be made of materials having different thermal expansions.
  • the metal absorption plate and the tube register are made of aluminum, copper, steel or other metal material.
  • the main advantage of the present invention is the small resistance against heat transfer from the absorption plate to heat transferring medium, trouble-free connecting of materials exhibiting different thermal expansions, long service life, good appearance of the absorber without damaging the absorption layer, easy stabilization of the absorber position relative to the transparent collector cover, trouble-free recycling in the case of the absorber separation from the tube register even in the case, when they are made of different materials.
  • the attached figure shows an absorber produced by the method according to the present invention.
  • an absorption copper plate 1_ of the thickness of 0.2 mm specially shaped hollowing 2 is pre-formed, into which a copper tube 3 is inserted, forming a part of the tube register 4.
  • the copper tube 3 fits with its diameter into the shaped hollowing 2.
  • the copper tube 3 is pressed in the absorption aluminum plate 1 in a special press so that most part of copper tube 3 surface is firmly locked in the tube register 4.
  • the method according to the present invention may be utilized in the production of thermal solar collectors.

Abstract

L'invention concerne un procédé caractérisé en ce qu'au moins un évidement (2) de forme spéciale est préformé dans une plaque d'absorption métallique (1) épaisse de 0,1 à 1,0 mm, évidement dans lequel on insère un tube (3) faisant partie du registre (4) de tubes d'un capteur solaire. Par la suite, on emmanche à la presse le tube (3) dans la plaque d'absorption (1) afin qu'il soit fermement bloqué dans le registre (4) de tubes. Avant de créer l'évidement (2) de forme spéciale, on peut revêtir la plaque d'absorption métallique (1) d'une couche absorbante. La plaque d'absorption métallique (1) et le registre (4) de tubes peuvent être fabriqués en aluminium, en cuivre ou dans une autre matière métallique, ou dans une combinaison de ces métaux.
