FIELD: heat supply systems. ^ SUBSTANCE: heating apparatus comprises pipes for supplying heat agent . The pipes are provided with heat exchanging surface that are secured to them and made of steel sheet. The heat exchanging surface is made of two steel sheets having semi-cylindrical sections which are in a contact with the surface of the pipe and flat sections. The sheets are mounted so that the pipes for supplying heat agent are positioned inside the semi-cylindrical sections. The sheets of the heat exchanging surface are made of material that possesses higher heat conductivity than that of the material of the pipes and are interconnected. The both sides of the heat exchanging surface are finned. The heat exchanging surface is detachable. ^ EFFECT: enhanced efficiency. ^ 2 cl, 2 dwg |
