Description

This invention relates to a radiator with a collector and radiating elements connected to said collector.

Radiator configurations are known, which include two cylindrical collectors and radiating elements in the form of tubes, each of which is mechanically and fluidly connected to these collectors.

These tubes are located outside the collectors and are perpendicular to them. Each of the tubes is mechanically connected to the outer surface of the collectors through two separate zones of the outer surface of each of these tubes, and the fluid enters the tube and leaves it through these two zones.

However, this connection geometry has certain disadvantages, which are that attaching the tubes to the outer surface of the cylindrical collectors by welding them to the collectors in those areas where they are in contact with each other is not simple.

In fact, access to areas in contact with cylindrical surfaces is difficult.

In addition, when painting a radiator, applying paint in these difficult-to-access areas is equally problematic.

Cleaning a radiator of this type by the end user of this radiator is also a difficult task.

Therefore, it is of interest to develop a new radiator geometry with a collector (collectors) and radiating elements connected to it (to them), made with the possibility of alleviating at least one of the above disadvantages.

Accordingly, the task of this invention is to create a radiator containing at least one collector and a plurality of elongated radiating elements, each of which is mechanically and fluidly connected to said at least one collector, and each elongated radiating element runs along its length, has a cross-section , defined by height Ni and width, and inserted at least on part of its length into the specified at least one collector at least on part a of height Ni, and 0.o5NnNIikani.

The insertion or embedding of radiating elements in the collector(s) provides an area/zone of contact between the emitting element(s) and

With a collector(s) larger than in the prior art, and therefore more accessible for interventions or operations thereon.

In particular, the attachment of radiating elements to the collector (collectors), painting of the radiator and its cleaning are greatly facilitated. In addition, this new geometry/configuration of connection/connection between the emitting element and the collector makes it possible to reduce or even prevent the corrosion phenomena occurring in the prior art near the interface between the emitting element and the collector.

Therefore, compared to the prior art, the internal passage section provided for the fluid between the collector and the radiating element can be increased, which provides the possibility of increasing the flow rate and promotes the internal circulation of the fluid. In some configurations, this can make it possible to increase the efficiency of heat transfer. In addition, pressure losses can be reduced. If the radiators are connected in series in a chain, this aspect can be interesting in that it becomes possible not to increase the pumping speed of this chain unnecessarily.

In addition, such a new geometry/configuration of connection/communication between the emitting element and the collector provides more flexibility in the choice of geometries and architectures of the radiator.

Note that the radiating elements can be completely inserted/built into the collector (collectors) in the event that a-No. However, the radiating elements inserted into the collector(s) remain flush with the upper outer surface of the collector(s).

According to other possible features: each emitting element is inserted into said at least one collector at least on part a of height No, and 0.05NoneNo, so as to mechanically fix this emitting element inside said at least one collector; this new configuration of connection or connection between the radiating elements and one or more collectors provides the possibility of mechanically fixing the radiating elements in the collector(s), since the depth of the insert exceeds half the height of the NS, but the radiating elements (eg, at least by means of their edge) remain visible in a plan view (front view of the radiator), perpendicular to the height of the radiating elements and showing the entire length of the latter, assembled with a collector (collectors);

each radiating element is inserted into the specified at least one collector for its entire height No, when the height of the specified at least one collector is greater than or equal to 1.2NOT the specified at least one collector has a generally elongated shape, and each of the radiating elements is inserted over part of the length of the specified at least one collector ; the specified at least one collector has a height perpendicular to its length, and each of the radiating elements is introduced to a part of the height of the specified at least one collector; each radiating element is fluidly connected to said at least one collector by means of one or more holes; said hole or holes has or have a total cross-section provided for the fluid, which is greater than the cross-section provided for the fluid in the configuration in which the radiating element is connected to said at least one collector without entering the interior of the latter; radiating elements are mechanically connected to said at least one collector by means of soldering or welding; the cross-section of the radiating elements, in particular, is selected from the following shapes: round, square, rectangular, triangular, oval, semi-oval, flattened oval, diamond-shaped; in general, the cross-section of the radiating element can have any polygonal shape; said at least one collector has a cross-section having a shape, in particular, selected from the following shapes: round, square, rectangular, triangular, oval; in general, the cross section of the collector can have any polygonal shape; radiating elements are located parallel or non-parallel to each other; radiating elements are located perpendicularly or obliquely in relation to the indicated at least one collector; not all radiating elements are located in the same plane; in a plane containing a longitudinal section of the specified at least one collector and

From the cross-section of the radiating elements, the cross-section of each of the radiating elements is made with the possibility of taking any angular orientation located in the plane, around the longitudinal axis of the radiating element (this axis is perpendicular to the plane mentioned above), and the said radiating elements have a cross-section of a non-circular shape ; it should be noted that this feature applies to cross-sections of non-circular shape (for example, square, rectangular, triangular, oval, semi-oval, flattened oval, diamond-shaped; generally speaking, the cross-section of the radiating element can have any polygonal shape), since there is no advantage in references to the geometric orientation of the circle in the plane; according to this feature of the geometric orientation of the circle in the plane of the faces (faces) of the radiating elements (three faces pass perpendicular to the cross-section) can take any possible angular orientation in the above-mentioned plane with respect to the adjacent surface or face of the collector (for example, the horizontal upper surface/face, when the collector is located horizontally, and the radiating elements are located on the side of the upper surface/face of the collector); the angular orientation of the cross-section is fixed for a given radiating element, but may take any value and may not be identical from one radiating element to another; therefore, the cross-section can be rotated to any angle (this angle depends on the shape of the cross-section and, therefore, for a square shape can be in the range from 0" to 90" inclusive, since after turning 90" the square returns to the previously achieved position) with respect to a base or neutral position (this position generally corresponds to the position in which geometric shapes are represented in a plane; for example, a triangle is represented with a horizontal base and an upward-oriented apex, and a rectangle is represented with longer sides located horizontally); here the radiating elements are generally perpendicular to the collector(s), but alternatively they may be located at an angle other than 90 to the collector(s); in addition to the indication of angular orientation, the radiating elements may be somewhat embedded/ inserted into the manifold and, for example, substantially embedded/embedded therein to provide mechanical locking as described above; emitting elements are connected to said at least one collector on any side of the latter; therefore, the radiator can have radiating elements located on two or opposite sides of the collector (collectors);

said at least one collector is selected from the following configurations: one collector, two parallel collectors located next to each other (the collectors can be located near one of the two opposite ends of at least some of the emitting elements or in the central part of at least some of the emitting elements), two parallel collectors spaced so in such a way that elongated radiating elements are inserted into these two collectors so that at least one of the two opposite ends of said radiating elements is located outside or inside the collector.

The object of this invention is also to create a radiator element containing at least one collector and at least one elongate radiating element, mechanically and fluidly connected to said at least one collector, and said at least one radiating element runs along its length, has a cross-section, defined by height No and width, and inserted at least on part of its length into the specified at least one collector on at least part a of height No, and 0.05Nika:no. Preferably, the insertion/embedding can be performed in such a way that 0O,O5NiIkaeni in order to mechanically fix the radiating element inside said at least one collector.

The radiator element has the same advantages and features as the radiator described above and will not be repeated in this document.

The task of this invention is also to create a radiator containing a radiator element of the specified type, in which each of the plurality of radiating elements is connected to the specified at least one collector. The features described above with reference to a radiator may also be applied herein to this new method of making a radiator based on a radiator element (a single element with at least one collector and one radiating element) that contains a plurality of radiating elements.

Other features and advantages will become apparent upon review of the following description, given by way of non-limiting example, and with reference to the accompanying drawings, in which: FIG. And 165 presents different forms of radiating elements, partially inserted into the collector;

For, as well as for different cross-sections; in fig. 9p presents another possible type of geometric orientation of radiating elements relative to the collector (collectors); in fig. 1O0a-k to illustrate various possible configurations or architectures of radiators in accordance with various embodiments of the present invention; in fig. 11a-c schematically present options for assembling by welding/soldering radiating elements with one or more collectors in accordance with one embodiment of the present invention; in fig. 12 shows a comparative view of a part of a conventional radiator and a part of a radiator according to one embodiment of the present invention.

Figure 16 schematically illustrates the principle of connecting the elongated 60 radiating elements to the collector in the radiator in accordance with one embodiment of the present invention. In fig. Fig. 6 shows a cross-section of different types of radiating elements, and their length in the longitudinal direction is perpendicular to the plane of the drawing.

This part presents the collector in cross-section along its length (truncated here).

Various possible cross-sectional shapes of the radiating elements are presented here in a non-exhaustive manner, but this does not mean that the radiating elements necessarily have different shapes in the radiator according to the present invention. In fact, all radiating elements may have the same cross-section, or at least one or more of them may have a different cross-section.

For simplicity in the remainder of this description, the radiating elements will be referred to as tubes, but it should be noted that their cross-section is not limited to the circular cross-section of the tube. In fact, elongated radiating elements or radiator tubes can take any cross-sectional geometry: square, diamond, rectangular, semi-oval, oval, oblate, triangular, etc.

One collector is presented here. It can be one radiator collector.

Alternatively, another collector may be present in the radiator, located parallel to the one shown in fig. 1a-B is therefore invisible in these drawings. The following description applies interchangeably to one or two manifolds unless the description of the embodiment does not explicitly state the number of manifolds.

The elongated tubes are mechanically and fluidly connected to the manifold(s) or connected to the manifold(s), although in FIG. and b is not presented (not presented) passage (passages) for the fluid medium between the tube (tubes) and the collector (collectors).

Here are the tubes perpendicular to the collector(s). However, in other, not shown, embodiments of the invention, the tubes may assume different geometric orientations with respect to the manifold(s), as will be explained later in this document, for example, an inclination of more than 907 with respect to the manifold as seen from the front of the radiator (the longitudinal axis of the tubes is no longer perpendicular the axis of the collector (collectors), but rather the slope in relation to them). Tubes can additionally (or instead of the above-mentioned slope) adopt an orientation different from that shown in fig. ta-yu, that is, the cross-section of the tubes is outside the limits

From the plane of these drawings, but oriented relative to this plane, and the longitudinal axis of the tubes remains perpendicular to the axis of the collector (collectors).

Also, when the radiator contains two manifolds, they may have different positions relative to the tubes. In particular, in the following description, if the drawing description mentions the end of the tube located near or in the manifold, the other manifold can be located anywhere, in other words, next to the first manifold or near or in the second manifold.

As shown in part in a substantially schematic manner in FIG. 1A-Y, tubes of various shapes are partially inserted or embedded in the interior of the manifold 10 for a portion of their cross-section and, in a manner not shown in these drawings, perpendicular to the plane of these drawings for a portion of their length.

The inserted part of the tubes 12 (flattened oval cross-section), 14 (square or diamond-shaped cross-section), 16 (circular cross-section), 18 (oval cross-section), 20 (rectangular cross-section), 22 (triangular cross-section) is marked with the letter a, while no the inserted or protruding part (outside the collector) is marked with the letter b.

In particular, the cross-section of the tubes is given, on the one hand, by a dimension (ar), called the height Ni, in a direction perpendicular to the length of the collector (this direction is also perpendicular to the longitudinal dimension of the tubes), and, on the other hand, by a dimension c, called the width, which is parallel the length of the collector.

The term "height" was used to refer to the size of the tubes (the size corresponding to the built-in height or depth), since in FIG. Yes, the tubes are located above the collector, but this does not mean that such a vertical location is maintained when the radiator is installed on site in the working position, in particular, against a vertical wall.

The distance or depth of the insertions or passages is given by the following formula: 0.05 mm, which guarantees a larger area of contact and connection between the tube(s) and the manifold(s) than in the prior art.

In the configuration in which a-0.05NI, the tube is inserted into the collector(s) only 5 95 of its depth, while with a-Ni the tube is fully inserted into the collector(s), while remaining flush with the outer surface ( here - the upper surface) of the collector (collectors). The last of these configurations is possible only when the height of the No collector 60 (collectors) is greater than or equal to 1.2NI (fig. Ta-r).

According to one particular embodiment, the spacing or depth of the insert is greater than or equal to 0.55NO. Such a dimensional relationship guarantees the mechanical fixation of the tube in the collector and, therefore, the mechanical fixation of the assembly consisting of the tube and the collector (the axial exit of the tube from the collector in the direction parallel to the insertion depth is prevented, or at least makes it difficult). In fact, in a configuration of this type, the connection zone between the collector and the tube passes behind the widest part of the tube (the part given width c, in Fig. 1 a-b), which is located inside the collector. In this type of configuration, the resulting plug-in assembly is easier to manipulate without the risk of disconnecting the tubes from the manifold(s) in a direction parallel to the embedment/insertion depth (perpendicular to the tubes and manifold(s)). This is especially useful when making a radiator when the various parts (tubes and manifold(s)) are not yet fully assembled together.

For example, parts may be mechanically assembled together but not fully assembled, for example, because no welding or soldering operation has been performed. It should be noted that in the variant implementation of the invention of this type, the insertion of the tubes into the collector is made in the direction parallel to the longitudinal axis of these tubes (the axis of the sliding connection between the tube and the collector), while in the case when a is less than 0.55NI, the insertion of the tube into the collector can be made on top of the collector, perpendicular to the longitudinal axis of the tube.

As shown in fig. Yes, each tube 12-22 is inserted on the part of the length of the collector(s) that corresponds to a greater extent of the width of the tube. In fact, the insertion depth may be such that the width of the tube is always outside the manifold(s). It should be noted that each tube is also inserted for part of the length of the tube, as shown in the following drawings, particularly in FIG. 2.

In fig. 2 shows a top perspective view of a part of the radiator (radiator lying horizontally) containing a plurality of parallel tubes 14 inserted into two parallel manifolds 30, 32 and spaced from each other so that each is located near one of the two opposite ends of each tube. In this embodiment of the invention, the opposite ends of the tube are free and pass in the longitudinal direction behind the collectors, but this method is not mandatory, and these ends (or only the ends of some tubes) can be attached to two collectors or only to one of them (asymmetric radiator configuration).

Each tube 14 is inserted into each collector in two separate respective zones which are spaced apart. Each tube is connected/connected to the manifold by a contact area near the end of the tube closest to the manifold. Thus, each tube is inserted for a portion of its length (located near one of its ends) into each of the two manifolds 30, 32. In this configuration, the distance or depth of insertion of the tubes 14 into the manifolds is greater than or equal to 0.55NO in order to provide the possibility of mechanical locking , as explained above.

As shown in fig. 2, the area of the collector 7c which is in contact with the tube 14 to connect them, passes in width from the tube which is located inside the collector 30. Here the same applies to each tube and each collector. Therefore, the upper edges of the zone 7c form mechanical elements or return elements for the axial retention of the tubes in the direction of the axis A, which is shown in fig. 2.

It should be noted that the distance Oss between the central longitudinal axes of the collectors 30 and 32 (interaxial distance) is at least equal to the largest transverse dimension of the collectors, perpendicular to the axis A. If this distance is equal to the largest transverse dimension of the collectors, then the corresponding outer surfaces of these two collectors are adjacent.

The minimum longitudinal size of the HER tubes should ensure the possibility of creating a fluid connection between the collectors 30 and 32.

The distance OK between the central longitudinal axes of two consecutive tubes (the distance between the axes) located in the same plane is at least equal to the largest transverse dimension of the tubes, parallel to the longitudinal axis or the direction of the collectors.

Although it is not represented in fig. 2, each fluid tube is connected to each manifold by means of one or more internal openings located within the mechanical connection/coupling zone 2c. Said orifice(s) have, for example, a total cross-section provided for the fluid that is greater than the cross-section provided for the fluid in the configuration in which each tube is connected to each manifold without entering an internal part of the latter (configuration of the prior art).

One manifold 30 or 32 carries the hot fluid and distributes it to the tubes 14 connected to it. According to one possible embodiment of the invention, one of the heating elements intended for heating the fluid is activated by a command, for example, using a control interface , placed outside the radiator, and when the collector is vertical, these control interface elements are usually located at the bottom of the radiator (not shown here). Another, distant, collector returns back the fluid medium, which has been cooled due to heat exchange with the walls of the tubes as it circulates in the tubes between the two collectors. The same principle applies when the manifolds are close to each other or even placed next to each other, or in the case where there is only one manifold containing within it a compartment for hot fluid and an adjacent compartment for cooled fluid.

In an alternative embodiment of the invention, there are no heating elements in the radiator, and the fluid (for example, water) is already hot when it enters the collector.

The tubes 14 are parallel to each other and, for example, assembled into groups of tubes (any number of tubes and groups of tubes can be used, and, in the extreme case, the tubes form one group of tubes). The number of tubes usually depends on the heat requirements that this radiator must address. The grouping of tubes creates a space between groups of tubes, in particular, in order to be able to easily place towels when the radiator is made in the form of a towel dryer, as in the case of the embodiment of the invention shown in fig. 2.

The fluid used is, for example, water, but other fluids such as oil can be used instead.

In fig. 2 presents tubes perpendicular to the collectors. However, in other, not shown, variants of the implementation of the invention, the tubes can take different geometric orientations, for example, can be inclined with respect to the collectors at an angle other than 907. The tubes can be located in a plane that is not parallel to the plane in which the collectors are located (for example , oblique to the latter; not all tubes must have the same orientation), oriented perpendicular to the latter or not. In addition, tube groups can take different orientations from one tube group to another.

In the images of the radiators illustrated in the various accompanying drawings, the tubes are located on the same side of the manifold(s) relative to the outer surface of that manifold(s).

However, in other configurations, the tubes may be located on either side of the manifold

Zo (collectors), on two diametrically opposite sides of the collector (collectors) or even, alternatively, on one side and on the other side with an axial displacement along the collector (collectors).

In fig. 1c illustrates a configuration of this type, in which the tubes 14 are located on each side of the collector 10, on two opposite surfaces behind and 5p of the collector. The distance between the axes or the distance OK between two longitudinal central axes of two consecutive or adjacent tubes (ОЩМа for tubes located on the surface За, and ОНБ - for tubes located on the surface 55) may be less than the largest width c or transverse the size of the cross-section of the tube, if the tubes are not located in the same plane, one is inserted into the manifold to a greater depth than the other. In the configuration shown, the tubes are arranged vertically one below the other, but in an alternative configuration, not shown, the tubes embedded in the surface 56 can be offset to the right or left with respect to the vertical and thus have an axial shift along the manifold relative to the tubes embedded in the surface behind. It should be noted that fig. 1c belongs to all types of tubes and all types of collectors regardless of their number, their shape and their position/orientation relative to each other.

The above description of the location of the parts of the radiator shown in fig. 2, can be applied to any other embodiment in which the tubes and/or collectors have a different cross-section or even a different geometric orientation. Also, not all tubes can have the same depth of insertion into the collectors. Collectors can have various cross-sections, such as: square, diamond, round, rectangular, triangular, oval, etc.

In the following figs. za-a, 4a-c and 5a-e illustrate different possible configurations of assemblies consisting of tubes and radiator collectors, assembled in different forms.

The above comments with reference to the geometrical orientation of the tubes relative to each other (parallelism, grouping of tubes, etc.) and to the manifold(s) and with reference to the depth of the insert also apply here. Likewise, the collectors may be differently positioned relative to one another, and alternatively, a single collector may be provided.

In fig. For the illustrated different positions (depths) of the insertion of the tubes 14 shown in fig. 2, in the collector 30: the position of the PI1 full insert, the position of the P2 insert at a-0.6nNI and the position of the RZ insert at a-0.05NI (there is no fixation). In positions RI and P2, the tubes are mechanically fixed inside the collector, as explained in this document above. Insertion into another manifold is

for example, identical in the case when the radiator contains two collectors. It should be noted that, of course, other intermediate insertion positions may be provided, and that this may apply to all drawings described hereinafter. Likewise, it is not necessary for all tubes to have the same insertion position, this may apply to all drawings described later in this document.

In fig. 30 illustrates different positions (depths) of inserting the tubes 16 shown in fig. Yes, in the collector 34 with a round cross-section. The same positions or depths of RI, Pa2 and RZ inserts, as in fig. As illustrated for the tubes 16. The insertion into another manifold can be, for example, identical in the case where the radiator contains two manifolds.

In fig. Cc illustrates different positions (depths) of the insertion of the tubes 16 shown in Fig. Yes, the collector 30 has a square or diamond-shaped cross-section. The same positions or depths of RI, P2 and RZ inserts, as in fig. Pros and cons illustrated for tubes 16. Insertion in another manifold may be identical, for example, in the case where the radiator contains two manifolds.

In fig. for the illustrated different positions (depths) of the insertion of the tubes 14 shown in fig. Yes, in the collector 34 with a round cross-section. The same positions or depths of RI, P2 and RZ inserts, as in fig. Za-c, illustrated for tubes 14. The investment in another collector can be, for example, identical in the case where the radiator contains two collectors.

In fig. 4a, 465 and 4c illustrate various positions (depths) of insertion of tubes into the collector, such as P1, P2 and R3, discussed in this document above: for tubes 18 with an oval cross-section, which are shown in fig. Yes, in collector 30 (Fig. 4a); for tubes 18 with an oval cross-section, which are shown in fig. 1a, in collector 34 (Fig. 45); for tubes 22 with a triangular cross-section (the base of the triangle is located inside the collector), which are shown in fig. 16, in collector 34 (Fig. 4c).

In fig. 5a and 565 illustrate different positions (depths) of inserting the tubes into the collector, such as

RI, P2, and RZ discussed herein above: for tubes 12 with a flattened oval cross-section, which are shown in FIG. and, in collector 36 with a square cross-section and an orientation shift at an angle of 457 relative to the collectors

ZO and 32 (Fig. 5a); for tubes 12, which are shown in fig. Yes, in collector 34 (fig. 560).

In fig. 5c illustrates the insertion of a plurality of tubes 14, 16 and 12 with different cross-sections into the manifold 38, and each of them has a fixed insertion position. Any position of the insertion of the tube into the manifold, containing the extreme positions and any intermediate position, is identified by means of references PI, 2, C in fig. 5c and in the following drawings.

Unlike other drawings where the ends of the tubes are free and pass behind the collector after the contact zone of the tube with the collector, here the ends of the tubes are inserted/embedded in the collector through the face or edge of Zva (no part of their lengths is located upstream of the free ends) and open to the collector. Alternatively, one end of the tube can be inserted into the manifold and its opposite end can be located behind the other manifold when the radiator contains two manifolds.

In fig. 5a is a view showing another way of arranging the tubes 16, 14 and 12, which are shown in fig. 5c, with less deep insertion positions.

In fig. , a cross-sectional view of the collector 38 shows a tube and collector assembly, with a tube of any cross-section, for example, type 12, 14, 16, 18, 20 or 22, shown in fig. Ta-Yu. This assembly illustrates the presence of an internal hole O for the fluid connection between the tube and the collector. The same type of internal opening can be created with other configurations of the assembly consisting of a tube and a collector. However, the shape and/or position of the hole may vary.

In addition, this arrangement shows that the length 1 of the built-in end of the tube must at least provide the possibility of accommodating the internal opening O inside the collector.

The tube and collector insert shown in fig. 4a-5e, for example, may be identical in another manifold in the case where the radiator contains two manifolds or, conversely, the length 1 may be different between the two manifolds or one tube may open to the outside of the manifold (the latter two configurations are not symmetrical).

In fig. 6 illustrates a radiator configuration in which a tube such as tube 16 shown in FIG. Ta-6 (although any other tube can be used) is partially introduced into two adjacent collectors 34 (a collector carrying a hot fluid medium), 35 (a collector carrying a cooled fluid medium after its passage into the tube 16), here - round 60 cross-section (other cross-sections of the collector may be provided).

The tube 16 has two opposite ends 1ba, 165 and contains between them (in length) pipe parts 16c, 16a, each of which is inserted inside one of the two collectors 34, 35. This configuration shows the presence of enlarged inlet and outlet internal openings O1, 02 of the liquid media for the fluid connection between the tube and the collectors.

The depth of insertion of the tube into the collectors may vary within the limits explained in this document above.

The radiator clearly contains other tubes not shown here.

Description of fig. 7-9 refers to the geometric orientation of the tubes with respect to the collector in the radiator in accordance with the present invention.

In fig. 7 presents a tube (radiating element) Its with any cross-section, which is presented here in the form of a polygon (however, it can have a shape that is not

It is polygonal and, therefore, does not have multiple faces, in particular beveled faces, but one face, such as, for example, an elongated, elliptical, etc. shape). The tube is partially embedded in the manifold 10 (it can be embedded in it at a greater distance, in particular, in order to mechanically fix the tube in the manifold, or even completely embedded), and various angular positions or geometrical orientations are illustrated (a), (B) and (c) the tube relative to the collector in the P plane containing the cross-sections of the tubes and the longitudinal section of the collector.

Given: two points A and B, located at the two ends of the longest edge of the polygon; axis AT, which is an axis passing through the outer surface of the collector adjacent to the tube (for example, the upper surface in Fig. 7); axis A?, which is an axis passing through the center of gravity d of the polygon and parallel to axis A1; axis 7 passing through the center of gravity 9 of the polygon and perpendicular to the axes A! and A2; angle a, which is the angle formed between the axis 7 and the segment |DA| in such a way that when this angle is zero, the segment |GIVE| parallel to axis 2. The segment |DA) is on the same line with the outer face of the tube, like another segment of the polygon. Therefore, it is clear that the different angular orientations that the segment (DA|Ї can take with respect to the adjacent external surface of the collector (axis

AT), correspond to different angular orientations of the corresponding outer face of the tube and, therefore, others

From the outer faces of the specified tube.

When the shape of any cross-section (not necessarily polygonal) and has only one face (and not many faces, as in the case of a polygon), the maximum angle "is equal to 360".

For more simple cross-sectional shapes, such as a square, the various possible angular positions are obtained by rotating through an angle between 0 and 90 degrees inclusive.

In the remaining part of the explanation relating to fig. 7, any cross-sectional shape is considered to have at least two faces, both having edges or segments of equal length.

If faces have edges or segments of unequal length, the maximum angle is assumed to be 360".

If any cross-sectional shape has only two faces, then the maximum angle is 180".

If и is a function of the number of faces of a cross-sectional shape with a minimum number equal to three faces, then the maximum value of the angle a is given by the following formula: atah-360/.

If y is equal to three, then atah-120".

Position (a) in fig. 7 corresponds to c - 0, position (B) corresponds to a positive non-zero angle « (the cross-sectional shape of the tube has changed its angular orientation with respect to position (a) by rotation around its center of gravity), and position (c) corresponds to the maximum angle. The tube can assume any angular orientation (geometrical orientation) about the longitudinal central axis of the tube between positions (a) and (c). After clause (c), the other clauses are identical to the clauses obtained between clauses (a) and (c).

As already stated in this document above, the tube can have any geometry and, in particular, one of those indicated in the drawings described above. The same applies to the geometry of the collector(s) of this radiator.

Considering a radiator containing at least one collector and a plurality of tubes, in a given configuration of such a radiator: the angle a can be the same for all tubes; angle a can be different for all tubes; 60 angle a can be the same for a given group of tubes and different for another group of tubes.

In fig. va, 86, vs, va and ve are illustrated for tubes with different cross-sections inserted into the manifold 10, different angular positions or angular (geometric) orientations obtained according to the explanations given with reference to fig. 7, with different, larger or smaller, angle a and different positions and/or depths of tube and collector insertion.

Plane P, shown in fig. va, is a plane containing the cross-sections of the tubes and the longitudinal section of the collector (the collector here is horizontal, but can be located, for example, vertically), in which changes in the geometric orientation/angular position of the tubes relative to the collector occur. In each drawing, the set of angular positions of the tube is illustrated according to the angle a formed between the axis marked by a dash-dotted line and passing through the center of gravity of the tube (the axis is contained in the specified plane) and the adjacent outer surface (here - the upper and horizontal surface) of the collector ( considerations are the same for a vertical collector). This axis is generally contained in the plane of symmetry or in one of the planes of symmetry of the tube, when such a plane of symmetry exists (such plane of symmetry is usually perpendicular to the plane containing the cross-section of the collector and the cross-sections of the tubes). In addition, in addition to the different geometric orientations, the tubes are inserted to a greater or lesser depth inside the collector 10, providing the possibility of mechanical fixation of the tubes in the collector or not, depending on the depth of insertion. Tubes 14, 12, 18, 20 and 22, described with reference to the previous drawings, are illustrated in FIG. wow Different possible angular orientations of the tube cross-section are obtained by rotating to a selected angle (for example, an angle between 0" and 907 inclusive or between 0" and 1807 inclusive or, again, between 0" and 360" inclusive, depending on the cross-sectional shapes considered ) of the cross-section of the tube around its longitudinal axis in the plane mentioned above in fig. va-e (longitudinal axis is the axis along which the tubes pass in a direction perpendicular to the plane mentioned above) from a base or neutral position, which generally corresponds to the position in which the geometric shape is represented in the plane: for example, a square is represented with two horizontal opposites sides and other two adjacent vertical sides; the rectangle is presented with two horizontal opposite longer sides and two adjacent vertical shorter sides; an elongated or elliptical shape is presented with a longer length, located horizontally, and

A triangle is usually represented with a horizontal base.

In fig. 81 schematically presents the first possible type of change in the geometric orientation/angular position of the tube relative to the collector, as illustrated in FIG. va-e, described in this document above.

In particular, in fig. 8th is a front view of a unit consisting of tubes and a collector, a radiator according to one embodiment of the present invention, representing a view in the longitudinal direction of the tubes 11 connected to the collector 10, in the projection on the plane P". The plane P' is perpendicular to the plane R. During such a change in geometric orientation, the longitudinal axis a!1 of the tubes (this axis passes through the center of gravity of the tubes) remains perpendicular to the axis of the collector 10, and the cross section of the tubes rotates around the axis a1, as shown in Fig. 7-8e.

Fig. ba schematically illustrates the second possible type of change in the geometric orientation/angular position of the tubes relative to the collector. This change in orientation, in particular, is reflected in the rotation of the longitudinal axis a2 of the tubes 12 in the P" plane with respect to the axis a1 in Fig. 8i. Therefore, these tubes are oriented obliquely with respect to the collector. It should be noted that this type of change in geometric orientation/angular position can be combined with the type shown in Fig. 87.

In addition, in the radiator according to one embodiment, not all tubes have the same geometric orientation (angular orientation) shown in FIG. 81 and/or 9a.

In fig. 90-9 show various possible tube shapes (shown partially in longitudinal direction) with a position in which the tube axis is perpendicular to the manifold axis and with a position in which the tube axis has been rotated relative to its previous position for each such shape. In this last position, the axis of the tube can be at an angle X to the longitudinal axis of the collector (or to the adjacent outer plane of the collector), such as b"X"180"7. The position in which the axis of the tube is perpendicular to the axis of the collector corresponds to an angle of 90".

In fig. 9r-c, da-e, 91-d show these two positions for tubes 16, 14 and 12, respectively.

In fig. 9 for a tube 14, for example, with a square cross-section and a collector 30 with a square cross-section, a change in geometric orientation or angular position perpendicular to the plane P" shown in Fig. 1a is shown (again, the tubes are oriented obliquely with respect to the collector). At the same time, the geometric the orientation or spatial position of the tube may be modified in this plane as indicated in Fig. 81 and/or 9a.

It should be noted that the above description regarding the change in the geometrical orientation or spatial position of the tubes relative to the collector in the radiator in accordance with the present invention applies to any shape of the tube and collector, whatever their number may be (the above-mentioned change can only be applied to some tubes and/or not be the same tube for all), their possible grouping and the degree or depth of insertion of the tubes into the collector(s). The insert need not be identical for all radiator tubes, and/or the geometric orientation need not be identical for all radiator tubes, and/or all tubes need not be the same shape in the same radiator, and/or the ends of the tubes do not necessarily have the same location relative to the two collectors in the case where the radiator contains two collectors.

In fig. 10a is a perspective view of a radiator-towel dryer KI according to one embodiment of the present invention, which includes two collectors C11 and C12, located next to each other, in a vertical position in the drawing, into which a plurality of tubes 16 are partially inserted (of course, other forms of tubes can be provided) . Here the tubes are grouped, for example, by four (of course, a different number of tubes can be provided), and, therefore, a set (here - five) of the groups would be spaced in the vertical direction behind the collectors. However, the indicated grouping of tubes is not mandatory.

In particular, the collectors C11 and C12 have a circular cross-section similar to the collector 34 shown in Fig. ЗB, За, 45 and 4с, but, alternatively, may have other forms. Alternatively, one manifold can replace these two manifolds.

In fig. 1065 presents in perspective the upper part of the radiator-towel dryer K2 according to one variant of the implementation of this invention, which contains two collectors C21 and

C22, spaced apart, in a vertical position in the drawing, into which a plurality of tubes 16 are partially inserted (of course, other tube shapes can be provided). Each of the collectors C21 and C22 is located near one of the two opposite ends of each of the tubes.

Equally, the tubes can be grouped as in the embodiment shown in fig. 1ba (here the tubes are grouped in groups of five), although this is not mandatory.

In particular, the collectors C21 and C22 have a circular cross-section similar to the collector 34 shown in Fig. ЗB, za, 46 and 4c, but, alternatively, may have other forms.

In fig. 10c shows in perspective the upper part of the radiator-towel dryer KZ according to one variant of the implementation of this invention, which contains two collectors SZ31 and

In particular, the collectors C41 and C42 have a square section similar to the collectors 36 shown in Fig. 5a, but, alternatively, may have other forms. Alternatively, a single manifold may be used.

Also, the tubes can be grouped as in the embodiment shown in fig. 10a (here the tubes are grouped by three), although this is not mandatory.

In fig. 10e is a perspective view of the upper part of the radiator-towel dryer K5 in accordance with one embodiment of the present invention, which includes one vertical collector C5, into which a plurality of tubes 12 with a flat cross-section are partially inserted (of course, other tube shapes can be provided). In particular, collector C5 has a rectangular cross-section similar to collector 38, shown in fig. 5с-й0, but, alternatively, it can have other forms.

Equally, the tubes can be grouped as in the embodiment shown in fig. 1ba (here the tubes are grouped by three), although this is not mandatory.

In fig. 10th is a perspective view of the upper part of the Kb radiator-towel dryer according to one embodiment of the present invention, which contains two C61 collectors and

C62, separated by a distance, in a vertical position in the drawing, as in fig. 1060, into which a plurality of tubes 12 with a flat cross-section are partially inserted (of course, other tube shapes can be provided). In particular, the collectors C61 and C62 have a circular cross-section similar to the collector 34 shown in Fig. 3B-a, but, alternatively, may have other forms.

Equally, the tubes can be grouped as in the embodiment shown in fig. 1ba (here the tubes are grouped by three), although this is not mandatory.

In fig. 109 shows the upper part of the radiator-towel dryer in perspective. K7 according to one embodiment of the present invention, which contains two collectors C71 and

C72, located next to each other, in a vertical position in the drawing, as in fig. 1ba (but on the other side), and in which a plurality of tubes with a flat cross-section are partially inserted (of course, other tube shapes can be provided).

Here, tubes 12 are connected to collectors C71 and C72 and inserted into them. Elements 11 and 12 serve to stiffen the free ends of the tubes and can take the form of one connecting element, for example, a metal rod.

In particular, the collectors C71 and C72 have a circular cross-section similar to the collector 34 shown in Fig. 3р-а, but, alternatively, they can have other forms. Alternatively, a single manifold may be used.

Equally, the tubes can be grouped as in the embodiment shown in fig. 1ba (here the tubes are grouped by three), although this is not mandatory.

In fig. 10p illustrates an embodiment of the radiator shown in fig. 104. Radiator

KV contains collectors C81 and C82 with a round, not square or rectangular cross-section, as in fig. 104. Except for this difference, all other aspects are identical.

In fig. 10i is a perspective view of the upper part of a radiator-towel dryer KO, according to one embodiment of the present invention, which includes a single collector 39, vertical in this drawing, into which a plurality of tubes 16 are partially inserted (of course, other tube shapes can be provided).

In particular, the SU collector has a rectangular cross-section similar to the collector 38 shown in Fig. Зс-й, but, alternatively, it can have other forms.

Here, the ends 1ba of the tubes, which are closer to the collector than the opposite ends 165 (the ends 165 are separated from the ends 1ba by the length of the tubes), are partially introduced into the CO collector and fixed in it, unlike the embodiment shown in fig. 10), at which end 1ba of the radiator

From K10 pass through the collector C10 and represent the free ends.

In fig. 10K illustrates another embodiment of the radiator-towel dryer K11, which is located, for example, vertically, and contains two collectors C111 and C112, located side by side, and a plurality of tubes partially inserted into the collectors. Here the tubes are located asymmetrically in relation to the collectors. Tubes are divided into groups. The group is positioned relative to the headers such that the longest length of tubing extends from one side, while the group located immediately below is positioned relative to the headers such that the longest length of tubing extends from the other, opposite side. Accordingly, as presented, the groups are staggered or staggered, and the collectors are located essentially in the middle of the radiator.

Any other geometrical arrangement of manifolds and tubes may be provided, whether grouped or not, for example with an alternating arrangement between two successive tubes.

The tubes are, for example, tubes 14 with a square section, although other sections may be provided.

The collectors have, for example, a square or rectangular cross-section similar to the collectors 30, 36 or 38 shown in the previous drawings, although other cross-sections may be provided.

Alternatively, a single manifold may be used.

In the description of fig. 10a-10K collectors are generally presented in a vertical position, and the tubes are in a horizontal position, but other spatial orientations can be provided, and, for example, the collectors can be located horizontally, and the tubes are radiating elements located vertically.

In one embodiment, the tubes are partially inserted into two manifolds in one of the possible configurations described above to form a mechanical assembly consisting of tubes and manifolds (in this temporary assembly the tubes and manifolds have their desired final functional position).

In fig. 11a illustrates the assembly operation by inserting tubes 16 into two collectors 34: the tubes 16 are inserted into the first collector in a direction parallel to the longitudinal axis of these tubes into cutouts ET made in advance (for example, by means of drilling, machining, etc.) in to each of the collectors 34. These cutouts, in general, are located in the transverse direction to the longitudinal axis of the collectors, and their contour corresponds to the external shape of the tubes and the required depth of insertion. The tubes were also drilled to make internal OD holes (here - oriented downwards) to make a fluid connection between the tube and the manifold. After that, the second collector 34 is raised from behind in such a way as to insert at the level of the opposite ends of the tubes 16, as shown by the arrows in Fig. 11a.

The resulting assembly is temporary and must later be fixed in a definitive way, for example, by welding/soldering the tubes with the collectors. Here, the insertion depth is such that the tubes are mechanically fixed in the collectors. In this configuration, a temporary welding operation is not necessary (optional) to provide mechanical strength to the resulting assembly.

The temporary unit is horizontally located on the support, which will later provide the possibility of easy manipulation of it when entering the furnace.

Then use a device O (for example, a tube or an injector) to apply the paste necessary for the next soldering operation. Here, this device provides the possibility of applying a plurality of spots in the corresponding places in the connection zone between each tube and each collector

Pb or droplets or droplet segments from a sufficient amount of copper paste. This operation is performed along the entire outer periphery of each connection zone between the tube and the collector.

The assembly formed of tubes and collectors is then introduced into the furnace by means of a support to perform a brazing operation (known per se) by melting spots or droplets or droplet segments of copper RU distributed along the outer periphery of each tube-collector junction area to final attachment of tubes to collectors.

Other types of attachment by means of welding (contact welding, etc.) may be provided for the final fixation of this unit.

In configurations where the insertion depth of the tubes into the headers is not sufficient to provide mechanical locking (and less than 0.55NI), temporary attachment of the tubes to the headers, for example by welding, is required.

In fig. 11c illustrates various welding technologies, namely laser welding using a laser welding machine 01, the head of which is presented, a welding machine ОИ МИС (tega!-ipegy da5 ueyiYidipudu, arc welding with a melting electrode in an inert gas environment) or TIS (Shshpodb5iep ipegi da5 meiYidipud, arc welding

With a tungsten electrode in an inert gas environment) of the type and device 0 described above, which, combined with a heat source, provide the possibility of soldering the applied paste. These technologies, in particular, the first two technologies, provide the possibility of temporary welding.

In fig. 12 shows a comparison of a conventional radiator configuration (left of vertical line) with a radiator configuration of the present invention (right of vertical line).

In the usual configuration, the tube ia is welded to the collector Ca at the level of the outer contact zones between these two elements, on either side of the hole Ca that passes through these two elements.

Welded seam 51, for example, is performed using the technology of contact welding or welding by spraying. When the tube and the collector are made of metal, a Faraday cage is formed in an area that is difficult to access and in which the metal elements are very close to each other.

Here, the zone in which the tube moves to the collector to make contact and weld with it (51) is represented by the arrows EI and forms a Faraday cage near the two adjacent metal surfaces.

Thanks to this, when applying paint to the radiator, for example, with the help of paint application technology in the electrostatic field, the E1 Faraday cage prevents the introduction of charged powder into this area and, therefore, the protection against corrosion of adjacent metal surfaces and the weld.

In the configuration according to the present invention (to the right of the vertical line in Fig. 12), the tube I is inserted into the collector 10 and welded/brazed there using any welding/soldering technology (contact welding, welding by spraying, brazing, oxy-acetylene welding, laser welding, etc.). The E2 zone, in which the metal surfaces of the tube and the collector are close to each other, and to which access is difficult, is much smaller than the E1 zone. The resulting Faraday cage is smaller, which for the resulting radiator greatly reduces the unpainted area and therefore the risks associated with corrosion.

For its part, the tube 12 is inserted deeper into the collector, and here the zone between the tube and the collector, which is difficult to access and which leads to the formation of a cage, disappears

Faraday. Only weld 53 is presented, which is made with the possibility of access for painting, thereby eliminating the corrosion risks associated with the presence of a Faraday cage.

Therefore, the corrosion phenomenon explained above is greatly reduced when the tubes are inserted into the manifold(s) and completely disappears from a certain insertion depth (typically when the insertion depth exceeds half the tube height in most tube and manifold configurations).

For fig. 12 it should be noted that due to the new geometry of the connection between the tube and the collector, the inner hole or holes of the MI and 12 tubes have been enlarged (although this is not mandatory).

All that was stated with reference to fig. 11a-c and 12, applied to any radiator configuration according to the present invention as described above.

The above explanation explains that even when the radiators are not painted (e.g. not made of metal), the geometry of the connection between the tube and the prior art manifold makes access to the ET area difficult, in particular for cleaning, which is much less in the case of not even in all cases with the geometry according to the present invention.
