SUBSTANCE: invention refers to heat power engineering and can be used at manufacture of boiler tubes. A production method of boiler tubes with different inner ribbed surfaces consists in the fact that a spindle calculated as per dimensions and provided with a pass having the specified shape of outer surface is made with coiling into the pass of a wire-like element forming on it a reverse image of the specified ribbed structure of a tube. A brazing metal paste is applied onto outer surface of the wire-like element and the spindle is introduced into the tube. In order to provide adaptation of the wire-like element to inner surface of the tube, the spindle is removed from above wire-like element and the tube is heated up to fusion temperature of the brazing metal paste to connect the wire-like element to inner surface of the tube, and then, the tube is cooled.

SUBSTANCE: for the purpose of water heating by solar radiation, a heat exchange panel with absorbing coating is put in a heat insulated casing with the glass through which the sun light reaches the surface of the panel, heats it and an attached pipe with a heat carrier, the heated heat carrier is delivered by the said pipe to the accumulation tank of a user. The heat exchange panel and method of its assembly comprises elements made from aluminium profiles with a heat carrier pipe being inserted in them, the flat surface of the aluminium profile of the heat exchange panel is fitted by V-shaped longitudinal grooves 0.5 mm wide and deep with the pitch between the centres of 10 mm and is coated by heat-proof paint diluted by a solvent, and the aluminium profile elements are made on the opposite sides with the edges forming a closed loop around the heat carrier pipe when one element is jointed with another, being a part of heat conducting section of the panel and ferruling it due to some structurally specified tension. Circulation of the heat carrier in the loop provides for the accumulation of hot water due to cooling of the heat exchange panel. For the purpose of maximal efficiency of the process it is necessary that the heat exchange panel is of minimal heat capacity but at the same time transfers heat to the heat carrier as fast as possible. The above is implemented in the proposed invention by manufacturing of the heat exchange panel from the material with good thermal conductivity - aluminium - and by the optimisation of the panel's heat conducting section for better heat contact with the heat carrier pipe.

EFFECT: profile has no additional surfaces not engaged in heat exchange process, maximal heat transfer to the heat carrier pipe is ensured due to the fact that it is closely embraced by one profile side and closed by another side with provision for necessary pressing.
