Description

Technical field

The invention generally relates to the field of heat exchangers. In accordance with the International Patent Classification (IPC Intcl.), the present invention is classified and designated F28; a broader classification that applies to heat transfer in general.

Since the invention is characterized by its construction, it may also be designated F28F - structural elements of heat exchange and transfer devices for general use.

Technical problem

Inventors have sought to improve the thermal performance of a heat exchanger core, primarily so that key operating fluid parameters can be easily controlled.

Hereby, using such an improved heat exchanger core, the inventors have developed a heat exchanger that is easy to manufacture, use and maintain, suitable for use in a variety of commercial and residential applications, as well as in various industries. The inventors also sought to design a heat exchanger that is lighter in weight than existing heat exchangers of the same capacity and the same material.

State of the art

The authors consulted patent databases and found that there are heat exchanger inventions that include a design that has spiral tubes, staggered tube spacing, and cross fluid flow, as in EP 0351247 A2 or US 20100096115 A1 Multiple Concentric Cylindrical Heat Exchanger with Co-Coils or US 3403727 A Countercurrent cross-flow heat exchanger with internal and external tube sections consisting of tightly packed, coaxially nested layers of helically wound tubes.

Some other similar inventions such as US 4893672 A Counter Flow Heat Exchanger with Spiral Tube Bundle or GB 685848 A Improvements related to the design of tubular heat exchangers do not include cross flow of fluids or staggered tube spacing. None of the previous patents disclose a counter-flow/cross-flow heat exchanger made by winding helical tubes (coils) into each other through structural reinforcements that are integral to the heat exchanger core and allow the coils to be staggered/zigzag and the tubes of each coil to be positioned precisely in the middle position and at the same distance between the tubes of adjacent coils throughout the heat exchanger core, and together they form the surface of the heat exchanger. In addition, none of these patents disclose structural reinforcements that are designed such that their inner and outer edges follow the required coil pitch, the inner edge follows the corner of the coil on which they are placed, and the outer edge follows the corner of the next coil. .

In addition, the device may include a central router having conical projections and a structural reinforcement support, wherein the base structural reinforcement on which the first helical coil is wound is placed on the central router having conical projections on both sides, the central router being configured to direct the flow of the first helical coil. fluid to the coils and preventing the first fluid from passing through the central portion of the heat exchanger core, wherein the conical projections direct the flow of the first fluid as close as possible to the outer walls of the coils through which the second fluid moves. All odd coils (first, third, fifth, ...) are parallel to each other in both the transverse and longitudinal planes of the heat exchange core, while all even coils (second, fourth, sixth, ...) are parallel to each other both in the transverse and longitudinal planes of the heat exchanger core. The diameters d of the pipes from which all coils are made are the same. Each coil in the heat exchanger core has a different diameter, with each coil having the same coil pitch, and each coil having a different coil angle. Structural reinforcements have a sinusoidal or wavy or wavy-zigzag shape, so that the shape of the structural reinforcements represents the supports on which the coils move when wound in gray

Carrying out the invention

A device for exchanging energy between media with improved design and characteristics in one embodiment of the invention contains the following parts: casing 104, screen 106, commutator (collector) 107, coils or spiral tubes 201, 2012, 203, 204, 205, 206, 207, 208 , 289, 290, tubes

- 3 045946 with extensions 110, central router 101 with conical projections 102, structural reinforcements 300, 301, 302, 303, 304, 305, 306, 307, 308, 389, 390 and structural reinforcement support 105.

In general, there will be basic structural reinforcements 300 placed on both sides of the central router 101 with conical projections on which the first helical tube (coil) 201 will be wound. The purpose of the central router 101 is to direct the flow of the first fluid 400 to the coils 201 , 202, 203, 204, 205, 206, 207, 208, 289, 290 and prevent the first fluid 400 from passing through the central portion of the heat exchanger core 200. The conical projections 102 direct the flow of the first fluid 400 as close as possible to the outer walls of the coils 201, 202, 203, 204, 205, 206, 207, 208, 289, 290 through which the second fluid 402 passes. The central router 101 is made of tubes of a certain diameter, to which conical projections 102 are welded on both sides.

The heat exchanger core 200 coils are formed on the tools. The tool can be a cylinder of a certain diameter and length, made of plastic or metal with channels corresponding to the required coil and its characteristics, while spiral tubes (coils) of given parameters are made by turning the tool. All odd-numbered coils, such as 201, 203-289, are parallel in both the transverse and longitudinal planes of the heat exchanger core 200. The same applies to coils with even numbers 202, 204, etc. The diameters d of the pipes from which all coils are made are the same. Each coil from 201 to 289, 290 has a different diameter, this applies to the diameter of the first coil 501, the diameter of the penultimate coil 589 and the diameter of the last coil 590. All coils have the same coil pitch, but a different winding angle, so that the first coil has an angle of 601 coil, the coil angle of the penultimate coil is 689, and the angle of the last coil is 690, so the tool is different for each coil. Coils can also be made on modified pipe bending tools, such as three-cylinder, drum tools and other tools known in the art. The tubes from which the coils are made can be made of copper, aluminum, stainless steel, bimetals, etc. The heat exchanger core 200 may be connected to heating or cooling systems vertically or horizontally.

Structural reinforcements 300, 301, 302, 303, 304, 305, 306, 307, 308, 389, 390 provide the ability to wind the coil into the heat exchanger core 200. Structural reinforcements 300, 301, 302, 303, 304, 305, 306, 307, 308, 389, 390 have a sinusoidal/wave/wave-zigzag shape. This form of structural reinforcement provides supports upon which the coils 201, 202, 203, 204, 205, 206, 207, 208, 289, 290 move as they are wound into the heat exchanger core 200. They are arranged parallel to the longitudinal axis 112, with the inner edge 291 and the outer edge 292 being formed in accordance with the required coil pitch 600. Since the coil angle of the coils 601, 689, 690 is different for each coil 201, 202, 203, 204, 205, 206, 207, 208, 289, 290, all structural reinforcements are different, designed so that the inner edge 291 follows this coil angle the coil on which they are placed, and the outer edge 292 follows the angle of the next coil. Thus, the first coil 201 has a diameter 501, a coil pitch 600, a diameter d of the pipe from which the coil 201 is made, a winding angle 601 and a first structural reinforcement 301, and so on for each subsequent coil. Similarly, the first structural reinforcement 301 placed on the coil 201 following step 600 also follows the corner of the coil 601 for the first coil 201 with an inner edge 291, and the outer edge 292 follows the corner 602 of the next second coil 202 and so on until the last coiled coil. At least two structural reinforcements 300, 301, 302, 303, 304, 305, 306, 307, 308, 389, 390, and most preferably three or more, located at equal distances along the diameters of the coils 201, 289, 290, are placed on each coil alternately. On each subsequent coil, structural reinforcements are placed so that they are not in the same plane as the reinforcements of the previous coil. The base structural reinforcement 300 is welded to the central router 101, and each subsequent structural reinforcement 301, 302, 303, 304, 305, 306, 307, 308, 389, 390 is alternately connected to the next wound coil in the heat exchanger core 200. The structural reinforcements also allow the coils to be staggered/zigzag and the tubes of each coil to be positioned exactly in the middle position and equally spaced between the tubes 320 (transverse to the second fluid 402) of adjacent coils throughout the heat exchanger core 200. After the structural reinforcements are placed on the last wound coil 289 or 290, a cylindrical heat exchanger casing 104 is placed on them. The base structural reinforcement 300 and the last structural reinforcement 390 may also be flat, without zigzag waves and other aforementioned characteristics, and may be flush with the structural reinforcement of the next coil that is attached to the base structural reinforcement 300, or with the structural reinforcement of the previous coil that is attached to the last structural reinforcement 390. In this case, the coils 201, 289, 290 with their pair of structural reinforcements 301, 389, 390, in turn, can be welded before being wound into the heat exchanger core 200, and then separately wound into the heat exchanger core in series.

Structural reinforcements ensure stability of the entire 200 heat exchanger core, reducing

- 4 045946 vibrations and uniform distance between the tubes of the heat exchanger 320. They further increase the heat exchange surface and, together with the coils, form a common heat exchange surface. Other modifications are also possible when bonding structural reinforcements other than welding, such as soldering, gluing, etc.

The structural reinforcements are most preferably made from the same type of material as the coils. Structural reinforcements are made from full profile materials, strips, wires, etc. or capillary tubes (microchannel tubes). They are manufactured into their own molds or cut, for example by laser cutting, to a specific shape which ensures that the coils are easily wound in series into the heat exchanger core. The thickness 310 of the material from which the structural reinforcements are made is one of the factors influencing the size (interspace gap) of the distance 320. Each structural reinforcement has the same thickness 310 of the material from which it is made. By changing the thickness 310 of their material, the size of the spacing 320 decreases or increases, but always ensures a staggered/zigzag arrangement of the coils and the tubes of each coil are positioned exactly in the middle position and at the same distance 320 between the tubes of adjacent coils throughout the heat exchanger core 200.

To avoid welding or gluing of structural reinforcements, all structural reinforcements can be inserted into symmetrical supports 105. In FIG. 9-15 show examples of a heat exchanger core 200 with supports 105 with eight cores 201-208. All structural reinforcements that are inserted into the supports 105 are made in accordance with the previously described principle. Each of the supports 105 is most preferably made of two identical full-section tubes or round rods that are welded at their centers at right angles. Between the supports 105, structural reinforcements are inserted into the holes 1050 drilled in them. In the above example, the last structural reinforcement is the eighth structural reinforcement 308. The supports 105 are made of the same type of material as the central router 101, with a diameter not exceeding the diameter of the coil tube 295. Each of the supports 105 has as many holes drilled as vertically , and horizontally, as much as necessary to place at least two structural reinforcements on each coil. The supports 105 may be welded to the center router 101 before welding its conical projections 102. After all structural reinforcements have been inserted into the supports 105 of FIG. 9-11 show coils 201-208 rotating alternately to form a heat exchanger core 200. In this case, structural reinforcements can be inserted into the supports 105 separately in turn after winding each coil.

Based on the required power of the heat exchanger core 200, the type, speed and temperature of the working fluids 400 and 402, as well as the required pressure drop of the working fluids, the length 120 and diameter 130 of the heat exchanger core are determined, the diameter d of the tube 295 for making coils is determined, and the wall thickness 311 of the tubes is determined. , from which the coils are made, the diameter of the first coil 501 to the diameter of the last coil 590 in turn, the number of coils and the required distance 320. By changing the pitch 600 of the coil and structural reinforcements, while maintaining the above-mentioned principle and characteristics of their manufacture, the distance 320 is easy to adjust, with allowing the desired fluid pressure drop 400 to be easily controlled. The length of each coil depends on the diameter of each coil, as well as the length 120 of the core itself.

Example of an optimized heat exchanger according to the present invention for a power requirement of 1850 W air-water.

Basic parameters for the manufacture of a heat exchanger core.

First fluid 400:

air

0.0934 [kg/s] mass flow of the first fluid 400

32.0000 [C] inlet temperature of the first fluid 400

Second fluid 402: water

4.8300 [1 t/min] second fluid stream 402

8.0000 [C] inlet temperature of the second fluid 402

The required pressure drop of the first fluid is 80 Pa and that of the second fluid is 6 kPa.

The optimized heat exchanger core according to the present invention has the following manufacturing specifications:

d= 0.0050 [m] outer diameter d of the tubes from which the coils are made

TW= 0.0005 [m] wall thickness of the tubes 311 from which the coils are made

- 5 045946

D= 0.2255 [m] wall thickness of the tubes 311 from which the coils are made

Sp= 22.00 total number of coils

Heat exchanger =4.7 [kg] core made of bulk copper

Distance 320 Lg = 0.003 m

As a result, the following parameters were obtained:

5842.15 [Pa] pressure drop of the second fluid 402

10.0884 [C] average temperature difference across the heat exchanger core 200

169.1566 [W/m2*K] average heat transfer coefficient

1848.7731 [W] thermal power extracted from the first fluid 400

All of the above structural and functional characteristics of the invention and the described example were successfully tested by the inventor on the developed prototype. By changing the described geometric parameters - the technical characteristics of the manufacture of the heat exchanger core, it can be used in residential facilities (lower power), as well as commercial facilities (higher power) and various industries for cooling, heating or recovery systems.

In the example described, an optimized heat exchanger core of small dimensions and light weight achieves a high thermal capacity (1850 W), allowing simple and flexible installation in a small space.

To facilitate winding of the coils in the heat exchanger core 200, each coil is cut at its beginning and ends so that all coils in the heat exchanger core reach the same normal plane on the axis 112. Tubes 110 with extensions of the same length are then placed at the beginning and end of each coil. on each coil separately. Holes 103 for the passage of tubes 110 with extensions, which then enter directly into the commutator (manifold) 107, are drilled on the casing 104. Tubes with extensions 110 can be welded, glued, etc. to the coils. A screen 106 is located between the core shell 104 and the extension tubes 110 to prevent the first fluid 400 from flowing beyond the heat exchanger core 200. The expansion tubes 110 are most preferably made of the same material and tube diameter d 295 as the coils and are expanded at one end where they will be drawn onto the coils using standard tube expansion tools. The switch (manifold) 107 additionally has holes 108 for ventilation of the heat exchanger core 200.

The first fluid 400 moves around the coils, and the second fluid 402 passes through the coils. The inlet 410 of the first fluid 400 with respect to the inlet 420 of the second fluid 402 is located on the opposite side of the heat exchanger core, so that the fluids move in opposite directions. Thus, the temperature difference in the entire heat exchanger core 200 is large, and the heat transfer in the entire device is high. The first fluid 400 further moves approximately perpendicular (transverse/normal) to the axis of the coil tube. With this arrangement, the coils significantly interfere with the flow of the first fluid 400, so that there is continuous turbulence of the first fluid 400 around the coils. This improves heat transfer, but also increases the pressure drop of the first fluid 400. Since the coils are staggered (staggered coils) in the heat exchanger core by placing them in their supports on structural reinforcements, the tubes of each coil are exactly in the middle position and at the same distance 320 (transversely the second fluid 402) between the tubes of adjacent coils, the first fluid 400 is forced to move near the walls of the coil tubes.

In a staggered arrangement, the tube of, for example, the fifth coil 205, as shown in FIG. 16 is located exactly in the mid-position between adjacent tubes of the fourth coil 204 and the sixth coil 206. The first fluid stream 400 passing between the fourth coil 204 and the sixth coil 206 meets directly with the tube of the fifth coil 205. The first fluid stream 400 passing between the fourth coil 204 and the sixth coil 206 does not generate or receive sufficient heat because it is located in the middle of the passage between the fourth coil 204 and the sixth coil 206, at the first point 430. However, it then passes near the tube wall of the fifth coil 205 at the second point 431 , where a lot of heat is released or received.

Heat transfer can be improved by reducing the distance from the tube walls to the first fluid 400, i.e. by decreasing the distance 320. If the distance 320 is very small, the flow of the first fluid 400 is forced to pass very close to the walls of the tube, hence the heat transfer is higher. In general, the thermal resistance of the flow of the first fluid 400 is proportional to the distance 320, such that the rate of heat transfer is proportional to the inverse length of the distance 320 between

Claims (10)

coil tubes: Q os Lg ' ^s However, if the distance 320 between the coils is too small, the first fluid 400 is forced to pass through narrow passages, so additional mechanical work is required to overcome the resistance, i.e. there is an increase in the pressure drop of the first fluid 400 through the heat exchanger core 200. This is an undesirable effect because some of the pressure is lost. The pressure drop of the first fluid 400 increases in proportion to the inverse cubic distance 320, i.e. The above-mentioned method according to the present invention can achieve maximum heat transfer for the default pressure drop of the first fluid 400. This solution allows the production of an axial helical counterflow (opposite direction) and crossflow heat exchanger core 200, as well as a staggered coil arrangement, which is obtained by simply winding spiral tubes (coils) sequentially over structural reinforcements, thereby achieving high thermal performance and simple control of the most important parameters. An additional benefit of the present heat exchanger core 200 is a self-cleaning mechanism for the interior of the coils. Scale, other deposits and contaminants within the coils cause a local increase in the velocity of the second fluid 402, which increases the frictional pushing of the clog between the second fluid 402 and the clog so that the interior surface of the coil cleans itself. The diameters 412 of the first fluid inlet 410 and the first fluid outlet 411, as well as the diameter 422 of the second fluid inlet 420 and the second fluid outlet 421 of the heat exchanger core, as shown in FIG. 17, can be made smaller or larger to fit standard connectors. Increasing the required power according to the present invention can also be achieved by coupling lower powers to a heat exchanger core 200 manufactured in accordance with the same principle. In fig. 12 shows an example of linking multiple lower wattage heat exchanger cores 200 manufactured in accordance with the present invention to create a single higher wattage heat exchanger. In fig. 9 shows an embodiment of the heat exchanger core 200 in cross-section with 8 coils 201, 202, 203, 204, 205, 206, 207, 208 so that it can be seen that first there is a base structural reinforcement 300, then a first coil 201, then a first structural reinforcement 301 on it, and then a second coil 202, which is placed in the recesses 294, while on the convexity 293 of the first structural reinforcement 301 there is a third coil 203, on which there is a third structural reinforcement 303, on which there is a fourth coil 204, which is placed in the recess 294 third structural reinforcement 303, while on the thickening 293 of the third structural strengthening 303 there is a fifth coil 205, on which there is a fifth structural reinforcement 305, and on it there is a sixth coil 206, which is placed in the recesses 294, while on the thickenings 293 of the fifth structural reinforcement 305 there is a seventh coil 207, on which there is a seventh structural reinforcement 307, and on it there is an eighth coil 208, which is placed in the recess 294 of this seventh structural reinforcement 307, while on the eighth coil 208 there is a last eighth structural reinforcement 308.

Fig. 11 illustrates one application of the invention in the automotive industry on a complete heat exchanger for cooling (intercooler) highly compressed hot air, where its purpose is to reduce the air temperature with the lowest possible pressure loss. Although the present invention has been described above in its most preferred embodiment, for a better understanding of the invention it should be borne in mind that various modifications are possible.
