Description

Title of the invention: Condenser and air cooler system with integrated folding feet, methods of transport and installation. TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to a condenser and air cooler system, as well as its transport and installation from its place of manufacture or assembly to its final installation location. TECHNOLOGICAL BACKGROUND

[0002] The systems covered by the invention are, generally speaking, air-cooled or gas-cooled heat exchangers. Such exchangers often comprise finned heat exchange tubes through which a fluid circulates. These tubes are located in a flow of gas or air generated by fans to remove heat from the fluids circulating within the tubes. More specifically, we will refer to condensers and air-cooled condensers, sometimes designated as "air fin coolers" or AFCs in English terminology. They can be used for cooling or condensing fluids in the oil and gas, energy, petrochemical, and data center industries, among other applications.

[0003] AFCs comprise a main bundle of finned tubes connected to manifolds whose function is to collect and distribute the fluid circulating in the tubes. These heat exchangers are generally equipped with 50 to 500 finned tubes and have geometric characteristics ranging from 5 to 20 m in length and from 0.3 to 5 m in width. These heat exchangers are supported by a steel structure that also supports the heat exhaust fans. The fans are arranged to generate airflow through the finned tubes, this airflow often being directed vertically and upwards.

[0004] The steel structure consists of columns, crossbeams, and beams that support the heat exchanger at a sufficient height to ensure optimal heat exchanger performance and prevent recirculation of the air supplied by the fans. The structure is designed to withstand wind, snow, seismic, and piping loads.

[0005] A condenser and air-cooled condenser system is usually transported in parts to an installation site, where it is assembled in its final location. However, this method of assembly becomes increasingly time-consuming, and therefore costly, at the installation site as the number of parts to be assembled increases. Description of the invention

[0006] A first object of the invention is to provide a condenser and air cooler system architecture that simplifies its on-site installation and associated costs.

[0007] In view of achieving these objectives, a first aspect of the invention is a condenser and air cooler system comprising a chassis extending in an extension plane, the chassis supporting: at least one fan arranged so as to be able to generate an airflow substantially perpendicular to the extension plane of the chassis; and heat exchange tubes arranged so as to be located in the airflow generated by the fan when the latter is in operation; and a support structure arranged so as to support the chassis, the support structure comprising folding feet arranged to be able to move from a first configuration called the "folded configuration" in which the feet are folded to a second configuration called the "deployed configuration" in which the feet are deployed, a footprint of the system in the folded configuration being less than a footprint of the system in the deployed configuration.

[0008] One advantage of the system according to the invention is that it can be transported in one piece, including the support structure. In this way, its installation at its final location is greatly simplified, as the assembly operations are deferred until prior to its transport for installation at its manufacturing site.

[0009] According to additional, non-limiting features of the first aspect of the invention, considered individually or in any technically feasible combination:

[0010] - the feet can each be fixed to the chassis via a respective mechanical linkage, such as a pivot, ball joint, slide, or annular linear joint, in the deployed configuration, the feet can each extend below the chassis from one of the respective mechanical links, in a direction substantially perpendicular to the plane of extension; in the folded configuration, the feet can each extend from one of the respective mechanical links, in a half-space limited by a lower part of the chassis and extending above the lower part of the chassis;

[0011] - the respective mechanical link can be a pivot link;

[0012] - in the folded configuration, the feet can each extend substantially in a plane parallel to the extension plane;

[0013] - the system may include at least two fans and at least two motors The chassis may comprise a main body and at least two support blocks attached to the main body, arranged to support at least two fans and at least two drive motors respectively, in which, in configuration When folded, the feet can each be located between two of the at least two support blocks;

[0014] - the support blocks can extend in a first direction which is substantially parallel to the extension plane, and, in folded configuration, the feet can extend in a second direction which is substantially parallel to the extension plane and substantially perpendicular to the first direction;

[0015] - the system may comprise at least one assembly consisting of one of the feet and of a folding brace arranged so as to, in deployed configuration, support this foot, the foot and the brace of the assembly being pivotally fixed to the chassis on either side of one of the support blocks;

[0016] - the foot of at least one assembly can extend from a first end fixed to the chassis at a second end opposite to the first end, an extension of the foot can extend from the second end in such a way that, in deployed configuration, the brace and the extension are aligned with each other;

[0017] - the bracket can be provided with a first stop configured to come into contact with a second stop for the extension of the foot and can be fixed there when the system switches to the deployed configuration;

[0018] - the bracket can be pivotally fixed to an upper part of the support block, the foot can be pivotally fixed to an upper part of the support block, and, in deployed configuration, the foot can also be fixed to a lower part of the support block;

[0019] - the system may further include a poacher retention element minus one set when the system is in folded configuration;

[0020] - the system may further include at least one lifting device attached to the chassis, configured to elevate the chassis from the ground or system support infrastructure.

[0021] A second object of the invention is to provide a method for installing the system according to the first aspect of the invention.

[0022] A second aspect of the invention relates to a method of installing the condenser and air cooler system according to the invention, comprising the steps of: transporting the system in folded configuration to an installation site; at the installation site, deploying the feet and, where applicable, the braces; and fixing the feet to a base for receiving the system.

[0023] The step of deploying the feet may include the use of lifting means integrated into the system so as to keep the chassis of the system away from the ground or infrastructure supporting the system.

[0024] A first advantage of the method according to the invention is that it results in a simplified, rapid, and economical installation of a condenser and air cooler system at its installation site.

[0025] A second advantage of the process is that it allows simplified management of the elements composing the system during its transport as well as its installation on site, since all the elements are gathered in the same means of transport, secured to each other. BRIEF DESCRIPTION OF THE FIGURES

[0026] Other features and advantages of the invention will become apparent from the detailed description of the invention which follows with reference to the accompanying figures in which:

[0028] [Fig.2] Fig.2 represents a condenser and air-cooled condenser system according to the invention, according to a perspective view illustrating the deployment of the feet;

[0032] [Fig. 6] Figure 6 illustrates a condenser and air-cooled condenser system equipped with means integrated elevation. DETAILED DESCRIPTION OF THE INVENTION

[0033] Fig. 1 illustrates a conventional condenser and air cooler system with vertical airflow. (A) shows a top perspective view, (B) a side view, and (C) a front view.

[0034] Such a system comprises a chassis 50 supporting fans 12, heat exchange tubes 16 which may be made of finned tubes, fluid inlet and outlet nozzles 15 mounted on manifolds 14, the manifolds 14 being arranged to distribute the fluid to the tubes 16. The system is configured such that, when in operation, the heat exchange tubes 16 are located in an airflow Fl generated by the fans 12.

[0035] The chassis 50 is supported by a structure comprising feet that maintain the chassis at a distance from its mounting support (typically, but not necessarily, the ground of its installation location). The support structure also includes braces 32 that diagonally connect the feet to the chassis, stiffening the structure. The feet 30 may be fitted with plates 34 designed to abut against the support. for installation, these plates may include openings for fixing the feet onto this installation support, for example by means of studs or any other mechanical assembly part.

[0036] A condenser and air-cooled condenser system such as the one illustrated in [Fig. 1] can typically have dimensions of approximately 20 m in length and 5 m in width. It may also include an access ladder 20 to an inspection and maintenance platform 22, the platform being equipped with a guardrail 18. Furthermore, the legs must be of sufficient size to keep the frame, and with it the air-cooled condenser, sufficiently far from the ground to prevent recirculation of the air blown by the fans generating the flow Fl indicated by the arrows in [Fig. 1]. The legs can therefore be several meters long.

[0037] Ordinarily, the system of [Fig. 1] is transported in separate parts, possibly individually, with these parts being assembled on-site at the system's final installation location. These on-site operations are time-consuming, subject to weather conditions, and costly, requiring a team to be present on-site for the time it takes to assemble and install the system.

[0038] To improve the conditions and speed of assembly, it is proposed to assemble the entire system at the factory and then transport it assembled to its installation site. However, the size of the system illustrated in [Fig. 1] makes its transport as such inexcusable, both technically and economically.

[0039] One solution to make this transport reasonable is to reduce its bulk by making the support structure foldable, or retractable, as for the particular embodiment of the invention illustrated by Figures 2 and 3. The basic principle is to equip the chassis with retractable feet, extending at least partially against the chassis in a first configuration called "folded configuration" and perpendicular to an extension plane of the chassis in a second configuration called "deployed configuration", the two configurations being such that the bulk of the folded configuration is less than the bulk of the deployed position.

[0040] The folded configuration is intended for transporting the system, while the deployed configuration is that of the system in operation, once its installation is complete. The system's footprint can be assessed by the minimum volume that a rectangular parallelepiped must occupy to encompass the entire system. This criterion allows for an evaluation of the feasibility of transporting the system by conventional means of transport, such as road transport.

[0041] Figures 2 and 3 illustrate a condenser and air cooler system according to the invention. [Fig. 2] shows perspective views from below and [Fig. 3] shows views side of the system according to the invention, going from a folded configuration in (A) to a deployed configuration in (C), and being deployed in (B).

[0042] The system illustrated in Figures 2 and 3 comprises a chassis 150 extending along a principal x-direction of extension along which the length L of the system can be measured. The chassis 150 supports fans 12 connected to respective drive motors 13 and distributed along the x-direction. The drive motors can be housed in support blocks 150b attached to a main body 150a of the chassis, and which extend beneath this main body in a y-direction perpendicular to the principal x-direction of extension of the main body. The width 1 of the system can be measured along the y-direction. The main body 150a of the chassis houses the heat exchange tubes 16, which also extend along the x-direction. The x and y directions define an xy-plane of extension of the chassis, intended to be horizontal, at least once the system has been installed at its installation site.In the deployed configuration, the feet extend along the z-direction normal to the x and y directions, under the chassis. In the illustrated geometry, the system height varies from hr to hd when moving from the folded to the deployed configuration, and can be measured along the z-direction.

[0043] In general, the frame 150 can support the same elements as the frame 50 of [Fig. 1]: fans 12, heat exchange tubes 16, manifolds 14 arranged to supply fluid to the tubes 16, and an access ladder 20 to an inspection and maintenance platform 22, the platform being equipped with a guardrail 18. Reference may be made to the descriptions associated with [Fig. 1] for the characteristics of these elements. Furthermore, as in the conventional system, the feet must have dimensions suitable for keeping the frame sufficiently far from the ground to prevent recirculation of the air blown by the fans.

[0044] The folded configuration is illustrated in (A) of Figures 2 and 3. This configuration shows feet 130 and 130b, intended to form a support structure for the chassis, folded along the chassis. The feet are attached to the chassis 150 (in this example, to the chassis support blocks 150b) by means of pivot joints, designated 130piv for feet 130 and 130bpiv for feet 130b.

[0045] The feet 103b are fixed to the chassis 150 at a first support block 150b (indicated by (1) in [Fig. 2](A)), located in a central part of the chassis, framed by a second and a third support blocks 150b (respectively indicated by (2) and (3) in [Fig. 2](A)). The feet 130 are fixed to the chassis 150 at the second and third support blocks 150b, located in end parts of the chassis 150 which frame its central part. The 130 feet can be fixed to the inner sides of the second and third support blocks, at the top of these blocks.

[0046] In addition to the folding feet 130 and 130b, folding braces 132 can also be attached to the chassis via pivot joints 132piv. In the deployed configuration, these braces 132 will support the feet 130, acting as spacers as will be detailed in relation to parts (C) of Figures 2 and 3. The braces are attached to the outer sides of the second and third support blocks 150b, possibly at the bottom of these blocks. In the folded configuration, the braces 132 can be held in place by fasteners 132fix.

[0047] In the folded configuration of this embodiment of the invention, the feet 130 and 130b can extend along the x direction, under the main body 150a of the chassis 150, between two of the support blocks 150b, as illustrated by Figures 2 and 3. This geometry has the advantage of minimizing the size of the system 100 in the folded configuration, the feet occupying free spaces within the volume of a rectangular parallelepiped encompassing the fans 12 and the chassis 150.

[0048] In this geometry, the braces can advantageously be held by the 132fix elements so as not to protrude from the parallelepiped defined previously, and therefore not to increase the bulk of the system in folded configuration.

[0049] The overall dimensions can, for example, be assessed by calculating the volume of the smallest rectangular parallelepiped encompassing all the elements composing the system 100. In the system illustrated by Figures 2 and 3, the overall dimensions of the system in its folded configuration could be calculated using the formula L x W x H, where L, L, and H represent the length of the system along the x direction, the width of the system along the y direction, and the height of the system along the z direction. The overall dimensions of the system in its deployed configuration could be calculated using a similar formula by replacing the height H of the system in its folded configuration with the height H of the system in its deployed configuration: L x W x H.

[0050] Depending on the requirements, the bulk could also be evaluated in both configurations, folded and deployed, according to one or more of the system dimensions along the x, y and z directions.

[0051] According to a first alternative configuration, not shown in the figures, the feet fold up to extend vertically along the sides of the chassis 150, preferably without their height exceeding that of the fans, so as not to increase the height of the system and therefore the vertical footprint (measured along the z-direction). This solution has the disadvantage of increasing the lateral footprint (measured along the y-direction) of the system in its folded configuration. The footprint calculated according to the calculation method above must take into account a change in the width 1 of the system going from the folded configuration to the deployed configuration.

[0052] According to a second alternative configuration, not shown in the figures, the feet fold so as to extend horizontally under the chassis in the y direction, preferably without their length exceeding the width of the system 100 or the width of the chassis 150 (its dimension in the y direction), so as not to increase the lateral space. In order not to increase the vertical space, the folded feet preferably occupy a volume located above a lower portion 150iow of the support blocks 150b.

[0053] Generally, in the present embodiment, the feet and any braces are pivotally fixed to the frame, and in the folded configuration, the feet 130 and 130b each extend from a lower portion 150iow of the frame 150 in a half-plane limited by the lower portion of the frame (in this case, the lower portion of the support blocks 150b, but which could correspond to a portion of the underside of the main body 150a of the frame if there are no support blocks) and extending above the lower portion 150iow of the frame. In the folded configuration illustrated in Figures 2 and 3, the feet 130 and 130b each extend substantially in a plane parallel to the extension plane of the frame, defined by the x and y directions.

[0054] Figures 2 and 3 illustrate in (B) the deployment of the feet and braces of the condenser and air cooler system illustrated in (A) of these figures.

[0055] Figures 2 and 3 illustrate in particular the rotations r of the feet 130 and the braces 132 around their respective pivot joints 130piv and 132piv at the beginning of deployment. At the deployment stage illustrated in the figures, the feet 130b are still completely folded; they will be deployed when the feet 130 located between the same support blocks 150b have given them enough space to be unfolded without risk of jamming or collision.

[0056] Each of the feet 130 constitutes a foot / brace assembly with one of the braces. Each assembly thus defined consists of a foot 130 and a brace 132 fixed to the same support block, on either side of it. Preferably, the brace is pivotally fixed to a lower part of the support block, while the foot is pivotally fixed to an upper part of the support block. Furthermore, the foot 130 and the support block may be provided with fastening means F1 and F2, respectively, intended to be attached to each other when the foot is fully extended. The fastening devices may, for example, consist of tabs having openings and provided to be fixed to each other by any known means of fastening such as bolts or rivets.

[0057] It will be shown in the figures that, for each assembly described above, the foot 130 comprises an extension 131 which extends from its opposite end to its end fixed to the pivot joint 130piv. This extension 131 extends in such a way that, in the deployed configuration, the brace 132 and the extension 131 are aligned with each other, as illustrated in (C) of Figures 2 and 3.

[0058] The foot / brace assembly configuration described above is advantageous because it allows for excellent compactness in the folded configuration, coupled with good rigidity of the resulting support structure (formed by elements 130, 131, 132, 130b) in the deployed configuration. Indeed, in the folded configuration, the foot and the brace do not increase the overall size of the system. Furthermore, the brace 132 can pivot so as to easily come into contact with the extension 131 of the foot 130, without being hindered by the presence of the support block 150b to which it is attached. Finally, the foot can also be fixed to the support block 150b by means of the fastening devices Fl and F2, ensuring, together with the pivot joint 130piv, a first level of rigidity to the support structure. This last point also applies to 130b feet and 130bpiv pivot links.

[0059] The free ends of the brace 132 and the extension 131 may be fitted with respective plates 132abut and 13labut configured to abut against each other. These plates may have openings and be designed to be fastened to each other by any known fastening means such as bolts or rivets. These plates may have the geometry illustrated in [Fig. 4], with a plate Abut having through openings Op, each designed to accommodate a bolt, a rivet, or any other fastening device.

[0060] Figures 2 and 3 illustrate in (C) the deployed configuration of the condenser and air cooler system shown in (A) and (B) of these figures. In particular, the legs 130, 130b and the braces 132 are fully extended, the system being installed at its site of use.

[0061] The feet 130 and 130b extend in the vertical direction z. The feet have butt and fixing plates 130abut, possibly of a structure similar to that described with reference to [Fig. 5]. The feet are thus configured to be fixed to a base for the system, possibly by means of studs inserted into the openings in the plates.

[0062] The plates 13 at the end of the extensions 131 of the feet 130 are each in contact with one of the respective plates 132 at the end of the braces 132. These plates can be attached to each other, in pairs, as explained above, forming fastening assemblies Asl. Also, the fastening devices Fl and F2 are attached to the They are attached to each other in pairs, forming As2 fixing assemblies. Finally, the 130abut stop and fixing plates can be attached to a docking station (not shown) of the condenser and air-cooled condenser system. All of these fixing points—Asl, As2, 130abut—ensure the rigidity of the support structure for the chassis 150 and the components it holds. In the illustrated example, it is assumed that only the feet 130 located at the end sections require support from braces to bear longitudinal loads, as opposed to the feet 130b, whose function is to prevent chassis deflection due to the weight of the system.

[0063] Although comprising a foldable support structure, the condenser and air-cooled condenser system according to the invention offers the same guarantees of structural strength as a fixed support structure mounted on the installation site. Its main advantage is its ability to present two configurations: a so-called "folded configuration," which is particularly advantageous for transporting the system, and a so-called "deployed configuration," which can be easily set up on the system's final installation site, according to the protocol described below and with the aid of [Fig. 5].

[0064] Fig. 5 illustrates a method 200 for installing the condenser and air cooler system according to the invention.

[0065] At a step 210, the elements constituting the condenser and air cooler system 100 of Figures 2 and 3 are manufactured independently of each other, and assembled in an assembly space, typically an assembly plant.

[0066] At a step 220 following step 210, the assembled elements are assembled together so as to obtain the system 100 in the folded configuration, as illustrated in (A) of Figures 2 and 3.

[0067] At a step 230 following step 220, the system is transported in its folded configuration from the assembly area to its installation site. Transport can be carried out by any means of transport, for example by road, sea, rail, or air. The folded configuration greatly facilitates transport, as well as the management of the system's components, since they are joined together and transported simultaneously by the same means of transport. This also has the advantage of facilitating the export and import of this type of product in certain countries. Indeed, the structural components transported separately would be taxed differently. A single assembled structure has a single customs code, which makes it possible to limit the tax to a single, more competitive rate.

[0068] At a step 240 following step 230, the system 100 is deployed, that is to say, its feet, and where applicable its braces, are unfolded so as to bring the system into the deployed configuration. This operation can be carried out, for example, with the system kept away from the ground or a system 100 support infrastructure by a crane, or any other suitable handling device.

[0069] As an alternative to using external handling equipment such as a crane, the system 100 can be equipped with integrated lifting means 160, as illustrated in [Fig. 6]. This option has the advantage of making the system self-supporting for lifting, and thus eliminating the need for external equipment. These integrated lifting means 160 are arranged to allow the chassis 150 to be lifted away from the support on which it rests, the ground, or a support structure Gnd of the system 100.

[0070] Figure 6 illustrates a chassis 150 equipped with a plurality of integrated lifting means 160, which can, for example, each consist of a jack device, a worm gear device, a jack device or any other mechanical device suitable for fulfilling the lifting function of the system 100. Figure 6 illustrates in (A) a configuration taken by the integrated lifting means 160 during a transport operation: they take a compact configuration, so as to minimize the size of the system. Figure 6 illustrates in (B) a configuration taken by the integrated lifting means 160 during an installation operation of the system 100: the integrated lifting means are elongated and capable of supporting the weight of the system 100, keeping its chassis 150 away from the ground or a support infrastructure Gnd of the system 100 and thus allowing the deployment of the feet 130 and 130b and the braces 132 as discussed above.

[0071] At a step 250 following step 240, the feet are fixed to a base for the system. The base may consist of a structure formed of beams intended to support the system via the support structure of the system itself. Alternatively, the base may consist of a concrete slab and / or concrete pads intended to receive the feet. The feet may be fixed to the base by means of the stop and fixing plates 130abut.

[0072] Preferably, the braces 132 are fixed to the feet 131, where appropriate via the extensions 131, by means of the plates 131abut and 132abut to form the fixing assemblies Asl.

[0073] Preferably, feet 130 and 130b are fixed to support blocks 150b to form the fixing assemblies As2.

[0074] The method 200 described above makes it possible to considerably reduce the time required for the installation of the condenser and air-cooled condenser system 100 compared to the installation of a conventional system, whose support structure is assembled on site, and not simply deployed and fixed. The assembly step is carried out at an assembly plant, where it is generally easier to perform the assembly than at the final installation site of the system.

[0075] The example described above by means of Figures 2 and 3 presents a particular embodiment of the invention in which the feet 130 and 130b and the braces 132 are fixed to the support blocks 150b. The invention is not limited to this particular technical solution, but extends to alternative technical solutions in which all or part of the feet and braces would be fixed to the main body 150a of the frame 150. Therefore, the positioning, number, and even the presence of the feet 130, feet 130b, and braces 132, as well as their characteristics, are naturally to be adjusted according to the load and the conditions of use (wind, snow, earthquake) of the system. The elements mentioned in this description may be made of steel.

[0076] The example described above by means of Figures 2 and 3 is that of an implementation of the invention by means of mechanical joints of the pivot joint type. Other modes of implementation can be envisaged, with other types of mechanical joints, such as ball joints, sliding joints or even annular joints, the essential point being to obtain two configurations, a so-called "folded" configuration with a small footprint for transporting the system, and a so-called "deployed" configuration for installing and operating the system.

[0077] Also, although used primarily for the purpose of keeping the air cooler or condensers sufficiently far from the ground to avoid recirculation of the air blown by the fans, the feet can be used for any other purpose, including for systems whose fans have an orientation other than the vertical orientation illustrated by the figures.

[0078] In this document, the figures are not necessarily to scale. Certain features and components may be shown exaggerated in relation to other components or in a somewhat schematic form, and certain details of conventional elements may not be shown in the interest of clarity and conciseness.

[0079] Also, when the description uses relative positioning terms such as "above", "below", or "under", the device should be considered in its expected position when in operation, with the feet in contact with a docking station or the ground, and fans arranged to draw air upwards.

[0080] Of course the invention is not limited to the embodiments described above and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.
