A heating device relates to heat supply and can be used for individual and centralized systems for heating dwelling and business premises. In the heating device that includes ribs as metal plates with one opening fixed with tight fit separately to each branch of the U-like tube with a gap between those from 3 to 10 mm the body has at the back panel a slot along the whole length and with width from 0.1 to 0.5 of its height, in the lower part of the back panel a screen is placed, this is bent to inside at angle from 10° to 80° with height from the lower panel to the lower edges of the plates, and at the front panel from one to 10 slots are placed along the whole length, with width from 0.05 to 0.5 of its height. The area of the plates is larger than the cross area of the tube 5-20 times, and the opening in the plates is arranged as a fillet part of which that is in contact with the tube has length from one to five mm. The bent sections of the slots of the front panel are bent to outside by angle from 10° to 60° from the plane of the panel. Use of the invention makes it possible to increase efficiency of heating premises through directing flow of heated air to floor and to decrease heat losses from the back panel of the device to the outer wall of premises, and makes it possible as well to increase efficiency of heat transfer from the tube to plates due to reliable contact of opening of plates on the surface of the tube. |
