Closest to the proposed technical solution is a heater protected by RF patent for invention N 2043580, containing horizontal heat exchange pipes installed with a clearance in a vertical plane, connected by a feces and U-shaped fins in plan, installed with a gap relative to each other and having lateral parts of the hole with rounded funnels. Source of information: the official bulletin of Invention N 25, 1995. , Moscow.

The purpose of the claimed utility model is to increase the intensity of heat transfer with the compactness of the heater.

This goal is achieved by the fact that the heating device contains two pairs of horizontal pipes 1 of the heating coolant located in parallel vertical planes, connected in series by U-shaped nipples 2 and connected to the heating system by means of an inlet manifold 3 and an outlet manifold 4. A pipe packet 5 is fitted with a heat pack 5 of vertically oriented elements of the fins 6. The element of fins 6 is a plate of sheet metal C-shaped in terms of shape with a side section 7 in the form of a square with side a, d including the front sections 8, the width of which is 0.1a and the flanges 9. Four holes 10 are made on the lateral section of the finning element with flanges 11 in the form of rounded funnels, which facilitates the assembly of the heater and ensures high-quality contact of the finning element with pipes. The distance between the holes is 0.5a.

To increase the intensity of the forced circulation of the heated air, due to the convection process, the fins elements b are assembled on the pipes end-to-end with each other, i.e. each subsequent fins element with its flanges 9 rests on the side section 7 of the previous element. Thus, the individual elements of the fins constitute a monolithic thermal package 5 with high thermal and strength characteristics.

The ends of the pipes 1 by which they are connected to the input and output headers are made in the form of IE bells into which the manifolds 13 of the manifolds are inserted. Similar sockets are made at the ends of U-shaped nipples connecting the pipes 1 in series.

Pipes 1 and U-shaped nipples 2 are made of steel

pipes followed by coating them with a layer of copper or zinc. Copper coating is carried out electrotechnically or by light soldering. Zinc coating is carried out electrotechnically or by cold galvanizing. The elements of the fins used are made of sheet steel with a thickness of 0.3-0.5 mm and are also coated with a layer of copper or zinc.

All parts in the heater are connected by soldering.

The ba of FIG. 1 shows a heater, general view;

in FIG. 2 shows a heater, a plan view;

in FIG. 3 shows a fin element of a heating device, side view;

in FIG. 4 shows a section AA in FIG. 3.

The heater operates as follows. The heater is connected to the central heating system by input 3 and output 4 collectors. In the input manifold, the heating medium is divided into two-flows and fed into the pipes 1, where it is cooled, transferring heat through the walls of the pipes and fins to the heated air. The cooled coolant through the output manifold 4 is returned to the central heating system. Due to the fact that the fins are made C-shaped from thin sheet steel coated with a layer of copper or zinc, they are assembled into a monolithic heat package 5, the device, with relatively small sizes and masses, has a significant heat transfer area, and the presence of vertical channels between the fins the flow of unheated air into the inner part of the heat package, which increases the efficiency of heating the premises.
