The invention relates to a power system, in particular the convective heating surfaces, namely the rows of heat exchange tubes, and can be used in air cooling units (ACU) gas.

Known pipe line with annular fins, which fins are made with a [-shaped profile and in the adjacent rows are oriented with their bends toward each other to provide turbulence in the flow of incoming air, and the heat exchange tubes connected with a coefficient of fins optimized to ensure compactness and reduction of metal with effective heat dissipation (SU 1476254). These pipes are difficult to manufacture, and to their distance in the range of the necessary elements of a complex configuration.

Closest to the invention in its essence and the achieved result is pipe series air cooler gas, consisting of pipes, which are sequentially placed in a row with a pitch axes. The tube is ribbed, and the Central longitudinal axis of tubes oriented predominantly in parallel (see, for example, V.B. have been Kuntysh, A.N. Sleepless and other "Fundamentals of calculation and design of heat exchanger for air cooling", St. Petersburg, Publishing house "Nedra", 1996, S. 36-40, RIS).

A disadvantage of the known structures is their lack of thermal efficiency is, providing the possibility of obtaining a compact heat exchanger only with pipes of great length. Increasing the length of the pipe up to 18 m in the traditional implementation, increasing hardware thermal capacity due to the increase in the area of heat transfer, reduces the rigidity and stability of the pipe line, significant deflections in the vertical plane, the violation of uniform bore for air, thus deteriorating the hydrodynamic conditions of the flow pipe line and reduced teploenergeticheskii characteristics against the settlement.

The objective of the invention is to increase the efficiency of pipe number of AVO gas in the process of its manufacture and operation, as well as increased reliability and durability.

The problem is solved due to the fact that pipe series air cooler gas, according to the invention, consists of finned tubes, consistently placed in the row with a pitch axes, the components of 1.7-3.4 diameter of the pipe body without taking into account the diameter of the fins, with the fins of each tube is transverse relative to the Central longitudinal axis of the pipe or angled to the axis, and the Central longitudinal axis of tubes oriented predominantly in parallel and are located in an imaginary plane normal to, etc) the PN flux of the external cooling medium, preferably air, and the pipe is placed with the formation of the thread in the projection on said notional plane aerodynamic shading with different aerodynamic transparency, consisting of sections full aerodynamic opacity corresponding to the projections on the said plane actually tel tubes without fins, and plots with incomplete aerodynamic transparency, each limited to one side of the notional line passing through the tops of the ribs, and on the other hand - the body contour of the pipe on the bases of the fins, the tubes in the tube row taken from the condition, according to which the value per unit area mentioned imaginary plane, the total of the areas mentioned areas with different drag the opacity respectively(0,25-0,52):(0,29-0,58).

Pipes in series may be arranged with gaps between the outer edges of adjacent finned tubes and the formation of gaps in the projection on a specified notional plane plots full aerodynamic transparency, the total area per unit area mentioned conventional plane is 0<S3≤0,46.

Pipes in series may be arranged adjacent the outer edges of the fins of adjacent tubes to each other.

Tubes in a row can be separated from each other discontinuously e the cops, made in the form of plates with alternating along the length of the plate convex and concave sections, forming a platform under the pipe.

At least part of the tubes of the row can be performed not less than two-layer materials with different thermal conductivity.

At least the outer layer of the pipe may be made of a material with greater thermal conductivity than the inner layer or inner layers.

The outer layer of tubes and fins can be made of vysokoteploprovodnyh metal or alloys, mainly from aluminum alloy with a thermal conductivity of not less than 5% greater than thermal conductivity of the material of the inner layer pipe, which is used preferably steel.

The outer layer of tubes and fins can be made of copper or copper-bearing alloys.

The outer layer of tubes and fins can be made of high strength and resistant to aggressive media material, mostly made of titanium or titanium containing alloys.

The external surface of the tubes and the fins can be covered vysokoteploprovodnyh and resistant to aggressive media material, for example a layer of aluminum or copper is deposited by electroplating or sputtering, or plating.

The finned tubes can be made is prohibited in the spiral form is wrapped around the pipe and attached to her body tape or in the form of ribs, formed by knurling the outer layer of the pipe.

The step edges of pipes may range from 1.8 mm to 5.4 mm

Fin tubes can be made thick by their external diameter component from 0.3 mm to 2.5 mm, and the area mates with the external surface of the pipe from 0.5 mm to 3.5 mm, and in this zone, the edge can be associated with a pipe on a curve, the radius of which is not less than half the thickness of the edge in the coupling zone.

Pipes can be made of bimetal with the external diameter of the inner carrier pipe, comprising 25 mm, wall thickness of 1.5-2.0 mm, an overall height of the ribs of the pipe 15 to 20 mm, the thickness of the rib on its outer diameter 0.5 mm, and the area mates with the outer surface of the outer layer tube of 0.8 mm, and the thickness of the outer layer of the pipe is 1-1,5 mm

The technical result provided by the present set of essential features is to improve teploenergetichesky characteristics of the pipe series by improving the conditions of flow tubes in a row working environment, and increase the service life of the pipe series by providing secure the pipe in the series when the same is hinnon the exception of the engagement of the edges of the pipes in a row and the absence of the stability of the bore for cooling air by optimizing the parameters of the pipes of the series.

FIELD: heating.

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. At least one heat exchanger purifies air. Several heat exchangers make the central heating system. Thermal pump system incorporates the heat exchanger.
