Definitions
- the invention relates to an element for an industrial-type heat exchanger, in particular a condenser, of the type comprising a generally tubular body.
- Condensers comprising such elements, also known as “tube condensers", are widely used industrially, particularly for the production of electricity.
- a first fluid typically water in the liquid state
- a second fluid in the gaseous state usually water vapor
- Industrial type condensers must be able to condense large amounts of steam in a minimum amount of time. The volume of vapor they are able to condense per unit of time at least partially characterizes their performance. To do this, industrial condensers are generally equipped with hundreds of tubes, or even thousands, of great length, typically up to twenty meters. In the beginning, industrial condensers were equipped with smooth tubes. In order to improve their performance, especially with regard to the flow of condensed vapor, new tubes of a new type have been started, the body of which retains its generally tubular shape but whose wall has a twisted shape extending on at least one segment of said body. This twisted shape of the wall results in an outer surface having a domed relief extending helically along the segment in question, and a correspondingly shaped groove on the inner surface of the body.
- This particular configuration substantially improves the heat exchange at the tubes: on the one hand, the twisted shape gives the wall a greater contact surface between the fluids, inside and outside the tubes; on the other hand, it causes turbulence in the fluid flowing inside the tubes, which is generally beneficial for heat exchange at the tube level.
- the twisted shape further improves the evacuation of the drops that form on the outer surface of the tubes.
- the tubes having a configuration of this type are said to be “corrugated”, or, more precisely, "provided with corrugations”.
- the pitch of the twist also called no corrugation, is generally greater than 20 millimeters.
- the invention aims to improve the existing.
- the proposed heat exchanger element comprises a tubular body whose wall is at least partially delimited an inner surface and an outer surface.
- the wall has a twisted shape on at least one segment of said body.
- the inner surface has at least one groove corresponding in shape with said wall and which extends helically on said segment.
- the outer surface has a diameter of between 18 and 30 millimeters, while the groove has a pitch of less than 3.5 millimeters and a depth such that the ratio of the pitch to a real power of between 1.5 and 2
- FIG. 1 shows a diagram of a generic heat exchanger
- FIG. 2 is a plan view of a tube element for the exchanger of FIG. 1;
- FIG. 3 is a longitudinal sectional view of a wall portion of a tube element for the exchanger of FIG. 1; - Figure 4 shows a twisted portion of a tube element for a heat exchanger, perspective view and partially cut.
- FIG. 1 shows, generically, an industrial type heat exchanger in the form of a condenser 1.
- the condenser 1 comprises a plurality of elementary tubes 3 held relative to one another in one or more bundles 5 by plates 7 distributed along the tubes 3. Each plate 7 is thus traversed by each of the tubes 3 of the bundle 5.
- the condenser 1 further comprises a pair of manifolds 9 into which the opposite ends of each of the tubes 3 open respectively.
- One of the boxes 9 is in fluid communication with a fluid inlet 11, while the other of these boxes 9 is in fluid communication with a fluid outlet 13.
- the inlet 11 and the outlet 13 may be connected to the remainder of a circuit in which a first fluid flows.
- the first fluid enters the condenser 1 through the inlet 11 in liquid form. It flows from the corresponding manifold 9 to the other manifold inside the tubes 3, in one or more passes. From there, the first fluid leaves the condenser 1 for the rest of the circuit through the outlet 13.
- the bundle 5 of tubes 3 is housed in an enclosure 15 formed inside what is called a shell 17 in the art.
- the calender 17 is equipped with a fluid inlet 19 and a fluid outlet 21 which open into the enclosure 15.
- the inlet 19 and the outlet 21 make it possible to connect the condenser 1 to a circuit in which a second fluid circulates.
- the second fluid enters the chamber 15 through the inlet 19 in gaseous form.
- the second fluid exchanges heat with the first fluid circulating inside these tubes. Since the first fluid is generally introduced at a temperature lower than that of the second fluid, the latter fluid condenses on the outer surface of the tubes 3.
- the second fluid in liquid form leaves the chamber 15 through the outlet 21.
- Capacitor type condensers 1 are widely used in the industrial production of electricity. In particular, it involves condensing water vapor with cold water circulating inside the tubes. To do this, we use tubes of great length, up to about twenty meters each.
- FIG. 2 It shows a TE tube element that can be used in a condenser type condenser 1.
- the tube element TE comprises a body BDY in the general shape of an elongate hollow cylinder, or tubular, of length TL.
- the body BDY has two longitudinal end sections ESI and ES2 connected to each other by a central section CS of length CL.
- the length TL corresponds to the total length of the tubular element TE, including the central section CS and the terminal sections ESI and ES2.
- the end sections ESI and ES2 are generally cylindrical, of outer diameter TOD.
- the diameter TOD corresponds to the nominal outside diameter of the TE element, as it is usually designated in the art.
- the ESI and ES2 end sections each have an outer surface and a smooth inner surface.
- the central section CS has a wall extending along the twisted body, or helically, or helically, forming turns LP around the longitudinal axis LA of the TE tube element.
- the LP turns are joined.
- the central section CS retains a general shape of hollow cylinder, having an outer diameter COD.
- FIGS. 3 and 4. show, generically, a twisted portion CW of the wall and a parameterization of this twisted shape.
- an internal surface IS having a relief made of peaks and valleys corresponding in shape with the hollows and bumps respectively of the outer surface OS.
- the inner surface IS is provided with a groove which extends along a helix with contiguous turns along the section CS.
- the inner surface IS has a helical shape.
- This relief is likely to improve the thermal exchange capabilities of the TE element, due to the generation of vortices in the fluid flowing inside the TE element.
- the twisted wall CW has a thickness TT.
- the thickness TT corresponds to the nominal thickness of the element TE, that is to say to the thickness of the wall of the smooth tube at the origin of the element TE.
- the central section CS has an inner diameter CID.
- the diameter CID corresponds to the diameter of a gauge just able to cross internally the element TE.
- the twisted section CS has an outer diameter COD which corresponds to the nominal outer diameter of the TE element on the twisted section CS, i.e. the diameter of a cylindrical envelope surface of this section.
- the twist shape has a pitch CP, if any considered inside the tabular element.
- the depth CD of the internal groove resulting from the twisted shape is considered with respect to an internal envelope surface of the tabular element, or, seen otherwise, as the radial distance between the bottom of the cracks of the inner surface IS and the summit of the ridges.
- T1D the dimension corresponding to the nominal internal diameter of the tube, as it is usually designated in the art, that is to say here the nominal internal diameter of the smooth end sections. ESI and ES2.
- the tube element TE has, on the twisted section CS, a nominal outer diameter COD between 18 and 30 millimeters.
- the CP pitch of the twist is less than 3.5 millimeters.
- the depth CD is such that the ratio of the high pitch CP to a real power R between 1.5 and 2.5 on the depth CD, called form ratio FR, remains below a ceiling value TV.
- the TV ceiling value is close to 24.
- the power R is close to 1.7.
- the depth CD satisfies the conditions COND1, COND2 and COND3 set out below:
- Tables 1A and 1B show that the twisted portion of the tubes according to the invention has a very small pitch, less than 3.5 millimeters, and preferably less than 3 millimeters, compared to the step values conventionally used in the tubes. with corrugations, typically greater than 20 millimeters. Therefore, the tubes according to the invention are distinguished from conventional tubes in that the twisted section has a shape that looks like a spiral.
- Table 2 below collects dimensional characteristics relating to a set of tube elements (referenced I, ..., XII) each having a twisted central section. The tube elements are distinguished from each other by the profile of their respective twisted section, characterized by pitch values CP and depth CD different from each other. Dimensions not shown in Table 2 are common to tubes I to XIV. In particular, the tube members all have an outer diameter of 22.22 millimeters and a wall thickness of 0.5 millimeters. The tubes are made of grade 2 titanium.
- CP step and CD depth values are in millimeters.
- Table 2 also shows the corresponding values of the form ratio FR, calculated for a power value R of 1.7.
- the tube elements II, III are in accordance with the embodiment variant 2.
- the tubular element III is also in accordance with the embodiment example 2.
- the elements I, II, III, V, and VIII are in accordance with the invention in that they have CP step values of less than 3.5 millimeters and furthermore check conditions COND1, COND2 and COND3.
- the tube elements IV and VI have dimensions according to the embodiment variant 2, except that they do not satisfy the conditions COND1 to COND3.
- Table 3 summarizes the results of heat exchange capacity measurements carried out on the elements of Table 2.
- the coefficient K represents a measured heat exchange capacity for the considered tube element.
- the coefficient K is expressed in Watt per square meter and per Kelvin (Wm "2 .K _1 ).
- the HER value expressed in percent, corresponds to the improvement in the value of K for the element under consideration in relation to a smooth element having similar dimensions elsewhere.
- Table 3 shows that compliance with conditions COND1, COND2 and COND3 is generally associated with a significant increase in heat exchange performance.
- the lines corresponding to the tube elements I, II, III, V, VIII, X and XII have values of the coefficient K which are at least 45% higher than the reference value for a smooth tube (5272 Wm -2 K. _1).
- the comparison in table 2 of the VII and X lines on one hand, and the lines I and XIII and XIV on the other hand also shows an increase in minor heat exchange performance when the report FR exceeds the ceiling value of 24. When the FR ratio is above the ceiling value, the increase in heat exchange performance compared to a smooth tube is generally less than 30%.
- Table 3 shows that the tubular elements in accordance with the invention have greatly improved heat transfer capabilities in comparison with smooth elements on the one hand, and elements whose twisted section deviates from the profile provided by the invention.
- Table 4 also collects the values of the so-called Darcy or Darcy-Weisbach coefficient for the tubes considered, as well as the DCR increase of the value of this coefficient relative to a smooth reference tube.
- the Darcy coefficient corresponds to a coefficient of loss of load. This size without dimension represents the influence of the type of flow (laminar or turbulent) and the appearance of a pipe (smooth or rough) on the pressure drop.
- the DARCY coefficient is calculated for a flow rate of 2.5 cubic meters per hour.
- An increase in the DARCY value is generally unfavorable to the performance of a tube element in a condenser.
- an increase in the DARCY value implies an increase in the energy consumption necessary for the circulation of the fluid inside the tubes.
- the increase in the DARCY value is detrimental to the condensation of the water vapor on the inside of the tubes. outside the tubular element with constant energy consumption.
- Table 4 generally shows that the tubes according to the invention show a significant increase in the DARCY value. However, this increase remains limited (less than 140 and less than for some tubes not according to the invention, as indicated by a comparison with the lines X and XII). On the other hand, the relative increase of the DARCY coefficient is very low (close, 100% or even less) for the elements according to the second embodiment variant (tubes II and III) and for the tube I, in comparison with the other tubes tested. The tubes of the second embodiment and the tube I show an increase in the value DARCY very significantly lower than the others.
- tubes having a twisted section according to the invention are capable of greatly improved performance with respect to their ability to condense an externally circulating gas. These improved performances are consecutive of a form of torsade which greatly improves the heat exchange capacities and significantly limits the effects of pressure drop.
- the tubes according to the embodiments 1 to 3, and to Examples 1 and 2 are likely to have even greater condensation performance due to the heat exchange capacity comparable to other tubes according to the invention and losses substantially reduced loads with respect to these tubes.
- the outer diameter of the TOD tube is between 19 and 26 millimeters, preferably between 20 and 26 millimeters, and even more preferably between 20 and 23 millimeters. millimeters. In particular, the outer diameter TOD is close to 19.05 millimeters, 22.22 millimeters, or 25.4 millimeters.
- the outer diameter COD of the twisted portion is between 18 and 26 millimeters, preferably between 20 and 26 millimeters, more preferably between 20 and 23 millimeters. In particular, the diameter COD is close to 18.90 millimeters, 22.07 or 25.25 millimeters.
- the pitch CP is strictly greater than 2 millimeters. It is less than 3 millimeters.
- the depth CD is between 0.05 and 0.6 millimeters, in particular greater than 0.15 millimeters.
- the thickness TT of the wall CW of the tube is between 0.4 and 1 millimeter, for example of the order of 0.5 millimeter.
