The invention relates to power engineering and can be used in the manufacture of devices for air cooling of the gas.

A known method of manufacturing a heat exchanger, which consists in assembling the components of the heat exchanger in the clamping device so that were separated by a gap pipelines separated by gaps tube passing between the piping side walls, which have between the pipes on the sides of the tank, and corrugated ribs, placed between adjacent tubes and between the side walls and the adjacent tube from each side of the frame, loosen the side walls at a point between its ends so as to reduce its ability to be resistant to stretching, but not substantially affect its ability to resist bending, and then subjecting the resulting Assembly to a temperature brazing to adhesions components together and make it possible to divide each side in the above-mentioned point in the feedback caused by temperature stress (see EN NO. 2001126260, F 28 D 9/00).

The closest analogue of the proposed method to the technical essence and the achieved result is the method of Assembly and installation of the tube bundle shell & tube heat exchangers, which produce sub-frame by means of connecting rods tube plate, Stantsionnaya gratings and the tube plate of the floating head. Then the frame is slid into the casing, the center of the frame relative to the flanges of this casing and attach it to the last. When this tube sheet is attached to the casing with rings, pins, nuts through the gasket and pipe Board floating head attached to the adapter by means of a split ring, welded to it nuts, studs, nuts through the gasket. On the other hand, the adapter is fixed to the casing by means of studs, nuts and gaskets. After installation of the frame in the casing to produce a packing of heat exchange tubes, which have technological allowance for machining. Then carry out the machining of the pipe ends so that their departure regarding, for example, the tube plate was depending on the welding method from 0 to 3 mm. Produce shallow mechanical expansion of the ends of the exposed pipes with the purpose of exposure of the size of the departure of pipes for quality of production welding. Next, carry out a preliminary weld groups of pipes, consisting of 10-20 pipes and symmetrically located about the axis of the frame. Then welded pipe handle at the other end for welding and weld pipe Board floating head. Thus, the tube plate over the entire area of tightly connected groups of heat exchange tubes, while performing the role of Contracting e the cops in addition to tagum. Conduct further welding of the pipe ends in the same sequence of alternating welding to the tube boards. After welding, the heat exchange tubes are expanding in the tube plate by any of the methods used in the technique. At the end of the control Assembly of the heat exchanger on the strength and density of the delay of the tubes in the tube plate, using the ring and adapter, contributing to job in the casing closed volume of the test environment. Then disassemble and remove the ring and the adapter, after which the tube bundle and the shell is ready for further Assembly (see SU 1210539, F 28 D 7/00).

SUBSTANCE: invention relates to heat engineering. The proposed device allows heat exchange between fluid medium and gas and comprises the casing, at least, one flat screen carcass made up of several heat-conducting-material capillaries arranged in parallel and equidistant relative to each other, and several heat-conducting-material wires connected to aforesaid capillaries to transfer heat via metal contacting, and pass at equal distance and crosswire relative to capillaries. The distance between wires approximates to that of their diametre. Gas flows along the wires to transfer heat to fluid medium that flows in capillaries, through capillary walls and via wires. The heat exchanger design allows the gas flowing along each screen carcass, lengthwise relative to the wires, and prevents flowing of a notable amount of gas through screen carcasses. The hothouse comprises soil surface with plants arranged thereon or in bearing pots, cultivation chute and, at least one heat exchanger. Note here that one gas inlet or outlet holes is located above leaf surface, while the other one is located below the said level, or both holes are located within the limits of the said surface.
