Description

background

The invention relates to a jacket element for a heat exchanger for controlling the temperature of a fluid. The jacket element of the heat exchanger is designed to hold a heat transfer fluid. The jacket element forms a peripherally closed fluid channel for a fluid which flows through the heat exchanger when in use and is heated or cooled by the heat exchange with the jacket element.

To improve heat transfer, such a jacket element is often designed as a double jacket. The double jacket represents a chamber through which a heat transfer fluid can flow.

State of the art

For example, in the document EP3444097 A2 shown a cooling element and a mixing element for a plastic melt. The plastic melt is mixed by means of the previously known mixing element and the plastic melt is cooled by means of the cooling element. The cooling element has a double jacket in order to cool the wall flow, ie the plastic melt flowing near the inner wall of the jacket element. When the plastic melt hits the mixing element, which protrudes into the core flow and has a corresponding guide element for this purpose, the wall flow and the core flow can be mixed with one another. The plastic melt flowing along the wall is deflected by the guide element in such a way that it is introduced into the core flow, as a result of which heat exchange between the cooled wall flow and the core flow is made possible.

If the heat transfer through the double jacket is not sufficient for the temperature control of the fluid, as in the EP 2851118 A1 , which discloses the preamble of claim 1, is shown, webs can be provided through which the heat transfer fluid located in the double jacket can flow. The webs are arranged in such a way that they traverse the fluid channel. The webs contain channels for the heat transfer fluid, which are in fluid communication with the chamber formed by the double jacket. It has been found that the heat transfer between the fluid and the heat transfer fluid can be improved with these webs. In addition, a mixing effect can be achieved by means of the webs, which means that, for example, a fluid consisting of several components can also be mixed through the webs designed as a mixer insert, which reduces the mixing effect Comparison to conventional tube bundle heat exchangers, see for example DE 199 53 612 A1 , improved. Such web elements are also in the EP3 489 603 A1 used. Cooling channels in the form of tubes with a circular cross-section can also be used for cooling bulk materials WO2018/023101 A1 or EP1 123730 A2 or in the form of tubes with a square cross-section according to DE 296 18 460 U1 or in the form of cooling channels with a zigzag cross-sectional shape according to FIG EP 0 004 081 A2 be provided. it's over EP 3 431 911 A1 also known to arrange multiply branched hollow structures consisting of pipe sections in a pipe. A heat transfer fluid, for example oil, flows through the hollow structures, and a compressible fluid, for example air, flows around the hollow structures.

In all previously known solutions that show web elements or tubes through which fluid flows, the heat transfer fluid is distributed to the web elements or tubes via a distribution channel and passes from the web elements or tubes into a collecting channel. The distribution channel thus contains only a single inlet and the inlet openings for the bar elements, the collector channel contains all the outlet openings of the bar elements and a single outlet.

However, it has been shown that the heat transfer fluid flowing through the web elements or tubes flows through the webs at very different speeds. Due to the design, the inlet openings of the web elements are arranged in the distribution channel at different distances from the inlet. Due to the design, the outlet openings of the web elements are arranged in the collector channel at different distances from the outlet. Due to the structural arrangement of the inlet openings in the distributor channel and the outlet openings in the collector channel, different flow speeds result for the heat transfer fluid. Therefore, with an increase in the number of web elements, such as in the EP 1 123 730 A2 shown, or an enlargement of the cross section of the web elements through which fluid flows, as in FIG EP 0 004 081 A2 disclosed, does not necessarily achieve a further improvement in the heat transfer, because the design-related different distances and thus the different flow velocities are maintained even with an increase in the bar elements or an increase in the cross section of the bar elements through which fluid flows.

object of the invention

It is therefore the object of the invention to ensure that as far as possible all chambers and the web element channels are flown through by the heat transfer fluid evenly. In addition, the object of the invention is to keep the pressure loss of the heat transfer fluid flowing through the web elements as low as possible or to reduce it to the lowest possible value in order to reduce energy costs for conveying means and/or pressure-increasing means, for example for pumps.

When the term "for example" is used in the following description, this term refers to exemplary embodiments and/or embodiments, which is not necessarily to be construed as a more preferred application of the teachings of the invention. Similarly, the terms "preferably", "preferred" should be understood as referring to one example from a set of exemplary embodiments and/or embodiments, which should not necessarily be construed as a preferred application of the teachings of the invention. Accordingly, the terms "for example," "preferably," or "preferred" may refer to a plurality of exemplary embodiments and/or embodiments.

The following detailed description contains various exemplary embodiments for a heat exchanger. The description of a particular heat exchanger is to be considered as an example only. In the specification and claims, the terms "include", "comprise", "have" are interpreted as "including but not limited to".

If the term "fluid" is used in the following description, this term also stands for "flowable medium" or "fluid mixture".

The object of the invention is achieved by a heat exchanger which comprises a jacket element and an insert element, the jacket element forming a fluid channel for a fluid, flowable medium or fluid mixture to be temperature-controlled. The insert element is arranged in the fluid channel. The insert member includes a plurality of web members connected to the shell member at different locations. The bridge elements are arranged in at least two groups of web elements, the web elements of each group of web elements being arranged essentially parallel to one another. The angles which the web elements of different groups of web elements enclose with the longitudinal axis of the heat exchanger differ at least in part. At least some of the bar elements contain bar element channels which are in fluid-conducting connection with the jacket element, so that in the operating state a heat transfer fluid which is supplied to the jacket element can flow through the bar element channels of the bar elements. The jacket element contains a plurality of chambers for a heat transfer fluid. At least one of the chambers contains a plurality of inlet openings and at least two outlet openings or a plurality of outlet openings and at least two inlet openings for the heat transfer fluid. Thus, at least one of the chambers has a plurality of inlet openings and outlet openings. In particular, at least two chambers can be provided, which contain a plurality of inlet openings and at least two outlet openings. In particular, at least two chambers can be provided, which contain a plurality of outlet openings and at least two inlet openings for the heat transfer fluid. Thus, at least one of the chambers has a plurality of inlet openings and outlet openings. In particular, at least two chambers have a plurality of inlet openings and outlet openings.

In particular, at least a first and a second set of web elements can be provided. The web elements of the first set of web elements are aligned parallel to one another, that is to say the web elements of the first set of web elements have the same alignment to one another. The web elements of the second set of web elements are aligned parallel to one another, that is to say the web elements of the second set of web elements have the same alignment to one another. The alignment of the web elements of the first set of web elements differs from the alignment of the web elements of the second set of web elements.

Of course, any number of first sets of web elements and second sets of web elements can be provided. Each of the first and second families of web elements may contain a different number of web elements. The number of bar elements of each group of bar elements can in particular be at least two. Of course, more than two sets of web elements can be provided, with the web elements of each of the sets of web elements having the same orientation as one another, but a different orientation to the web elements of each other set of web elements exhibit. For example, the web elements of three web element crowds according to FIG. 10 of EP 1 123 730 A2 be aligned.

The inlet openings and the outlet openings, which are located in the same chamber, are preferably associated with web elements of different sets of web elements. The distance covered by the fluid between the inlet opening and the nearest outlet opening in the same chamber is smaller than the distance between two inlet openings of adjacent unidirectional web element sets. This ensures that the dwell time of the heat transfer fluid in the chamber in the jacket element is as short as possible, since it can flow directly from the outlet opening into the nearest inlet opening. Therefore, advantageously, inlet openings and outlet openings of different sets of web elements are combined in a common chamber, the distance between which is smaller than the distance between the inlet openings of adjacent, parallel sets of web elements.

In particular, at least some of the bar elements that are provided with bar element channels and lead to the entrance of the chamber do not run parallel to one another, or at least some of the bar elements that are provided with bar element channels and lead out of the chamber do not run parallel to one another. The heat transfer fluid which flows through the web element channels therefore has a different temperature depending on the orientation of the web elements. The fluid that flows around the web elements is thus exposed to locally different temperatures. As the fluid flows around the web elements, this fluid is constantly divided and rearranged, which leads to its mixing. If the fluid is exposed to different temperatures depending on the alignment of the bar elements, these temperature differences can quickly equalize due to the mixing effect of the bar elements, because the fluid is better mixed, which in turn has an advantageous effect on the heat exchange.

In particular, an inlet for the heat transfer fluid can be provided in the jacket element. In particular, an outlet for the heat transfer fluid can be provided in the jacket element. According to one embodiment, the jacket element has at least three chambers for the heat transfer fluid. The heat transfer fluid may be mixed and redistributed in at least the chambers containing a plurality of inlet ports and a plurality of outlet ports. These chambers are thus designed as mixing chambers for the heat transfer fluid.

According to one exemplary embodiment, at least some of the chambers can be at least partially separated from one another by partition walls. According to one embodiment, at least one of the chambers contains an intermediate wall.

According to one exemplary embodiment, at least one of the chambers is connected to a further chamber via the web element channels. In particular, the inlet openings and/or outlet openings of different chambers can be at least partially connected to one another via web elements that run through the fluid channel. According to this exemplary embodiment, at least part of the heat transfer fluid flows sequentially through a number of mixing chambers. The heat transfer fluid can be remixed and distributed in each of the chambers, which have multiple inlet openings and multiple outlet openings. In particular, it is possible for the heat transfer fluid to flow transversely or counter to the flow direction of the fluid.

According to an exemplary embodiment, each of the chambers can extend over part of the circumference of the casing element. In this way, several chambers can be arranged next to one another on the circumference of the casing element. When the heat-carrying fluid sequentially flows through these adjacent chambers, a transverse flow of the heat-carrying fluid occurs with respect to the direction of flow of the fluid.

According to one embodiment, the width of the chamber, which contains the plurality of inlet openings and the at least two outlet openings or the plurality of outlet openings and the at least two inlet openings, can be at most the same size as its length. In particular, the length of the chamber can be greater than its width. According to one embodiment, the width of the chamber can be at most half the length of the chamber. According to this exemplary embodiment, the length of the chamber is measured parallel to the longitudinal axis of the heat exchanger. The width of the chamber is measured in a plane normal to the longitudinal axis of the heat exchanger. In this context, a normal plane is a plane which is arranged at a right angle, that is to say at an angle of 90 degrees, to the longitudinal axis of the heat exchanger. The width may extend along a straight line when the heat exchanger is rectangular. The width of the chamber can also extend along a line of curvature, for example in the form of a segment of a circle if the heat exchanger is in the form of a cylinder.

According to one embodiment, the length of at least one of the chambers can correspond to the length of the casing element. If the heat transfer fluid of a chamber over a Inlet is supplied, which has a smaller distance from the outlet opening of the heat exchanger than from the inlet opening, the heat transfer fluid can flow against the flow direction of the fluid.

According to one embodiment, at least some of the bar elements are oriented at an angle other than 90 degrees to the longitudinal axis of the heat exchanger. The longitudinal axis of the heat exchanger corresponds to the main flow direction of the fluid. In particular, the angle of the bar elements can differ from one another, in particular at least one first bar element can be arranged crosswise to a second bar element.

According to one embodiment, a chamber has at least two inlet openings and at least two outlet openings. According to one embodiment, a chamber has at least four inlet openings and/or at least four outlet openings. In particular, a chamber has at least four inlet openings and at least four outlet openings.

According to one embodiment, at least one of the chambers covers at least 10 to 80% of the surface of the jacket element. According to one embodiment, all of the chambers cover at least 10 to 80% of the surface of the jacket element. According to one embodiment, all of the chambers cover at least 50 to 80% of the surface of the jacket element.

According to one embodiment, one of the chambers has a width that is 10% to 100% of the circumference of the jacket element. According to one embodiment, one of the chambers has a width that is 50% to 100% of the circumference of the jacket element. According to one embodiment, one of the chambers has a width that is 70% to 100% of the circumference of the jacket element.

Each of the chambers can have a length and a width and a height. The length of the chamber is its dimension parallel to the flow direction of the fluid, i.e. parallel to the longitudinal axis of the heat exchanger. The width of the chamber is the dimension transverse to the direction of flow of the fluid, i.e. the dimension of the chamber measured in a normal plane to the longitudinal axis of the heat exchanger, i.e. the normal plane is arranged at right angles to the longitudinal axis of the heat exchanger. The height of the chamber corresponds to the distance between the outer wall of the casing element and the inner wall of the casing element. In particular, the ratio of the width of a chamber to the length of the chamber can be a maximum of two. In other words, according to this exemplary embodiment, the width of the chamber is at most twice as large as big as their length. In particular, the ratio of the width of a chamber to the length of the chamber can be at most one. This means that the width of the chamber is essentially as large as its length. In particular, the ratio of the width of a chamber to the length of the chamber can be a maximum of 0.5. In other words, according to this exemplary embodiment, the width of the chamber is at most half as large as its length.

According to one exemplary embodiment, the heat transfer fluid can flow through a number of chambers, for example at least one of the chambers can be connected in a fluid-conducting manner to at least one of the other chambers through openings in at least one of the partition walls. In particular, the heat transfer fluid can flow through more than two or more than three chambers; the chambers can be connected to one another via the web element channels and/or via openings in the partition walls.

According to one embodiment, the inlet openings and the outlet openings, which are located in the same chamber, belong at least partially to bar elements of different sets of bar elements. In particular, at least some of the web elements that are provided with web element channels and lead into the chamber do not run parallel to one another. In particular, at least some of the web elements that are provided with web element channels and lead out of the chamber do not run parallel to one another.

A method for temperature control of a fluid, flowable medium or fluid mixture includes the temperature control of the fluid by means of a heat exchanger, the heat exchanger comprising a jacket element and an insert element, the fluid flowing in a fluid channel enclosed by a jacket element. The insert element is arranged in the fluid channel, the insert element containing a plurality of web elements which are connected to the shell element at different locations. The bar elements are arranged in at least two groups of bar elements, the bar elements of each group of bar elements being arranged essentially parallel to one another. The angles which the web elements of different groups of web elements enclose with the longitudinal axis of the heat exchanger differ at least in part. At least some of the web elements contain web element channels which are in fluid-conducting connection with the casing element, so that in the operating state a heat transfer fluid which is supplied to the casing element can flow through the web elements. The jacket element comprises a plurality of chambers for a heat transfer fluid, wherein at least one of Chambers has a plurality of inlet openings and / or outlet openings for the heat transfer fluid.

In particular, the inlet openings and/or outlet openings of different chambers can be connected to one another via bar elements that run through the fluid channel, so that heat can be transferred between the heat transfer fluid and the fluid via the inner wall of the jacket element and the bar elements.

According to various variants of the method, the heat transfer fluid flows through the chambers and/or the web element channels in the direction of flow of the fluid and/or counter to the direction of flow of the fluid and/or transversely to the direction of flow of the fluid.

According to a variant of the method, the heat transfer fluid flows from an outlet opening in one of the chambers to an inlet opening in another chamber through a bar element channel which is arranged in a bar element which is arranged in the fluid channel. In particular, at least one of the inlet openings and one of the outlet openings of a chamber can be arranged such that the heat transfer fluid in the chamber flows in a direction transverse to the main flow direction of the fluid, with the main flow direction of the fluid corresponding to the longitudinal axis of the heat exchanger.

According to a variant of the method, the heat transfer fluid can flow in the chamber essentially along the connecting line between the centers of the inlet openings leading into the chamber and the outlet openings leading out of the chamber, with the connecting line being arranged at an angle to the center axis of the web element channel, the angle being in the range from 30 degrees up to and including 160 degrees.

In particular, the heat transfer fluid can flow in the web element channels in the direction of flow or counter to the direction of flow of the fluid.

The invention thus relates to a heat exchanger that can be produced at low cost and that can also be used as a static mixer, or a static mixer that can also be designed as a heat exchanger at the same time or can include the function of a heat exchanger. The heat exchanger is particularly suitable for cooling or heating flowable media, for example fluids, with the fluids being able to include, for example, viscous or highly viscous fluids, in particular polymers. If such a device for processing highly viscous fluids, such as polymer melts is used, the static mixers used there typically have to withstand nominal pressures of 50 to 400 bar and temperatures of 50 to 300 degrees Celsius.

Heat exchangers are used in many areas of the processing industry. According to one embodiment, a flowable medium can be moved over at least one stationary insert element. The insert element usually contains built-in elements which bring about a deflection of the fluid stream or the free-flowing medium that is guided through the interior space of the insert element, which is delimited by an insert casing element. A heat transfer fluid flows through the built-in elements. The flowable medium flows through the insert element by generating a pressure gradient. The pressure gradient can be generated, for example, by using pumps.

Fig. 1b shows the jacket element 2 with the installed insert element 3. The jacket element 2 has an inlet opening 5 and an outlet opening 8 for a fluid or fluid mixture which flows through the heat exchanger in the operating state. The jacket element 2 is designed as a hollow body, for example as a double jacket, which means that inside the jacket element 2 there are a plurality of chambers. A heat transfer fluid flows through these chambers in the operating state. The flow of the heat transfer fluid is shown in the present representation by dash-dotted lines with two dots between two adjacent dashes. The double jacket is formed by an outer shell and an inner shell. The outer shell is in Fig. 1b shown transparent to allow a view of the chambers of the casing element 2.

The jacket element 2 contains at least one inlet 20 and one outlet 30. The jacket element 2 according to FIG Fig. 1a or Fig. 1b consists of four chambers. The first chamber 21 contains the inlet 20, comprising a tubular element containing an inlet channel for a heat transfer fluid. The third chamber 23 contains the outlet 30, which includes a tubular element containing an outlet channel for the heat transfer fluid. Between the first and third chambers 21, 23 are a second and a fourth chamber 22, 24.

According to the present embodiment, each of the first and third chambers 21, 23 is larger than the second and fourth chamber 22, 24. In particular, each of the first or third chambers 21, 23 comprise more than 10% each, in particular more than 25% each, of the circumference of the jacket element 2.

According to Fig. 1a the first chamber 21 extends from the inlet opening 5 to the outlet opening 8 for the fluid which flows through the jacket element 2 in the operating state. According to this exemplary embodiment, the first chamber 21 extends over the entire length of the jacket element 2. The first chamber 21 forms, according to FIG Fig. 1b shown position from a part of the top surface of the casing element 2 and the side surface adjacent to this top surface. The second chamber 22 comprises that part of the top surface of the jacket element 2 which is not occupied by the first chamber 21 . A first partition wall 31 is located between the first chamber 21 and the second chamber 22. The second chamber 22 extends from the inlet opening 5 to the outlet opening 8 for the fluid which flows through the casing element 2 in the operating state.

According to this exemplary embodiment, the third chamber 23 extends over the entire length of the casing element 2. In other words, the third chamber 23 extends from the inlet opening 5 to the outlet opening 8 for the fluid which flows through the casing element 2 in the operating state. The third chamber 23 is adjacent to the second chamber 22 . According to the Fig. 1b In the position shown, the third chamber extends over the side surface adjacent to the top surface, which is opposite the side surface formed by the first chamber 21 . In addition, the third chamber 23 forms part of the base area of the casing element 2 . There is a second partition wall 32 between the second chamber 22 and the third chamber 23 . The second partition wall 32 prevents heat transfer fluid from being able to get from the second chamber 22 directly into the third chamber 23 . In this case, directly means inside the hollow body spanned by the jacket element 2 .

A fourth chamber 24 adjoins the third chamber 23 and extends over part of the base area of the casing element 2 . The fourth chamber 24 is also adjacent to the first chamber 21 . There is a third partition wall 33 between the third chamber 23 and the fourth chamber 24. There is a fourth partition wall 34 between the fourth chamber 24 and the first chamber 21. According to this exemplary embodiment, the fourth chamber 24 extends over the entire length of the casing element 2 In other words, the fourth chamber 24 extends from the inlet opening 5 to the outlet opening 8 for the fluid which flows through the jacket element 2 in the operating state.

According to the present exemplary embodiment, the first chamber 21 has three inlet openings 40 which are in fluid-conducting connection with channels which run within the web elements 9 which adjoin the first chamber 21 . In the operating state, heat transfer fluid can flow through these inlet openings 40 into the web elements 9 , which in the present illustration adjoin the first chamber 21 and extend to the fourth chamber 24 . In the fourth chamber are located in this Fig. 1b not visible outlet openings, through which the heat transfer fluid can escape from the web element channels and can enter the fourth chamber 24. The heat transfer fluid flows through the fourth chamber 24 to the inlet openings, which open into the channels of the parallel bar elements 9 and into the channels of the bar elements 10 arranged crosswise to the bar elements 9, which extend from the fourth chamber 24 to the second chamber 22. The heat transfer fluid exits through six outlet openings 50 from the channels of the bar elements 9, 10 and into the second chamber 22. The outlet openings 50 are in Fig. 1a and Fig. 1b painted black to distinguish it from the entry openings. The heat transfer fluid flows through the second chamber 22 to the inlet openings that open into the channels of the bar elements 10 that extend from the second chamber 22 to the third chamber 23 . The channels of a part of the bar elements 10 , in the present exemplary embodiment three bar elements 10 , thus open into outlet openings which open into the third chamber 23 . The heat transfer fluid enters the third chamber 23 via these outlet openings, which are not visible in the present illustration, and can leave the jacket element 2 via the outlet 30 . Part of the heat transfer fluid also flows through the chamber part of the third chamber 23 that is adjacent to the right-hand side surface. Heat exchange between the heat transfer fluid and the fluid can thus take place both via the walls of the web elements and via the chamber walls of the first to fourth chambers 21, 22, 23, 24 take place.

1c shows a section through a heat exchanger 1 according to Fig. 1a or Fig. 1b .

At their second end 14 , the web elements 9 form a fluid-tight connection with the inner casing element wall, which forms one of the boundaries of the first chamber 21 . The heat transfer fluid can thus not come into contact with the fluid flowing between the web elements 9, 10. The heat exchange between the fluid and the heat transfer fluid thus takes place via the inner jacket element walls of the jacket element 2 and via the web element walls of the web elements 9, 10 of the insert element 3.

According to the exemplary embodiment shown, in the first chamber 21 there is an intermediate wall between the web elements 9, whose central axes span a common plane, and the web elements 10, whose central axes span a common plane.

A plurality of the heat exchangers 600 according to Figure 8b can be arranged one behind the other in the flow direction of the fluid, i.e. before or after the in Figure 8b The heat exchangers shown can be connected to one or more other heat exchangers 600. Adjacent heat exchangers 600 can be rotated about the longitudinal axis, i.e. the Figure 8b Web elements shown vertically can, for example, run horizontally if the angle of rotation is 90 degrees, which is not shown in the drawing. A staggered arrangement of a plurality of heat exchangers can not only improve the heat exchange and result in a more homogeneous temperature distribution in the fluid, but also improve the mixing effect in the fluid.

The jacket element 602 has an inlet opening 605 and an outlet opening 608 for the fluid, free-flowing medium or fluid mixture, which flows through the heat exchanger 600 in the operating state. The jacket element 602 is designed as a hollow body, for example as a double jacket, ie inside the jacket element 602 there are a plurality of chambers. A heat transfer fluid flows through these chambers in the operating state. The flow of the heat transfer fluid is shown in the present illustration by dash-dotted lines with two points between two adjacent ones shown in dashes. The double jacket is formed by an outer shell and an inner shell.

A fourth chamber 624 adjoins the second chamber 622 and extends over a further segment of the casing element 602 . The fourth chamber 624 is also adjacent to the sixth chamber 626 . There is a third partition wall 633 between the second chamber 622 and the fourth chamber 624. There is a fifth partition wall 635 between the fourth chamber 624 and the sixth chamber 626. According to this exemplary embodiment, the fourth chamber 624 extends over the entire length of the casing element 602 In other words, the fourth chamber 624 extends from the inlet opening 605 to the outlet opening 608 for the fluid which flows through the casing element 602 in the operating state.

A fifth chamber 625 , which extends over a further segment of the jacket element 602 , adjoins the third chamber 623 . The fifth chamber 625 is also adjacent to the seventh chamber 627 . There is a fourth partition wall 634 between the third chamber 623 and the fifth chamber 625. There is a sixth partition wall 636 between the fifth chamber 625 and the seventh chamber 627. According to this exemplary embodiment, the fifth chamber 625 extends over the entire length of the casing element 602 In other words, the fifth chamber 625 extends from the inlet opening 605 to the outlet opening 608 for the fluid which flows through the jacket element 602 in the operating state.

There is a fifth partition wall 635 between the fourth chamber 624 and the sixth chamber 626. There is a seventh partition wall 637 between the sixth chamber 626 and the seventh chamber 627. According to this exemplary embodiment, the sixth chamber 626 extends over the entire length of the casing element 602. In other words, the sixth chamber 626 extends from the Inlet opening 605 to the outlet opening 608 for the fluid which flows through the jacket element 602 in the operating state.

A seventh chamber 627 adjoins the sixth chamber 626 and extends over a further segment of the casing element 602 . The seventh chamber 627 is also adjacent to the fifth chamber 625 . The seventh partition wall 637 is located between the sixth chamber 626 and the seventh chamber 627. The sixth partition wall 636 is located between the fifth chamber 625 and the seventh chamber 627. According to this exemplary embodiment, the seventh chamber 627 extends over the entire length of the casing element 602. In other words, the seventh chamber 627 extends from the inlet opening 605 to the outlet opening 608 for the fluid, which flows through the jacket element 602 in the operating state.

According to the present exemplary embodiment, the first chamber 621 has at least one inlet opening 640, which is in fluid-conducting connection with at least one bar element channel 611, which runs inside the bar element or elements 609, the channel or channels adjoining the first chamber 621. In the operating state, heat transfer fluid can flow through this inlet opening 640 into the web element(s) 609 , which in the present illustration adjoin the inner wall of the chamber 621 and extend to the second chamber 622 .

In Figure 8b only a single set of web members 641 are shown disposed at a first angle to the longitudinal axis 604 and a single set of web members 651 are shown disposed at a second angle to the longitudinal axis 604, the first angle being different than the second angle. At each of the web element crowds 641 and 651 further bar element crowds can connect what the Figure 8c is shown. In Figure 8c a second, third and fourth family of web elements 642, 643, 644 are shown, each of which is arranged parallel to the first family of web elements 641. In the Figure 8c Also shown is a second, third and fourth set of web elements 652, 653, 654, each of which is arranged parallel to the first set of web elements 651.

Therefore, the heat transfer fluid according Figure 8b flow into a single bar element channel 611 of the bar element family 641 or into several bar element channels 611 of the bar element families 641, 642, 643, 644 lying one behind the other in the flow direction of the fluid as in Figure 8c is shown. In the following, the variants according to Figure 8b and Figure 8c described together, so that there is always a variant of the following description should be included with a single bar element channel or several bar element channels of different groups of bar elements.

According to Figure 8a the heat transfer fluid enters from the first chamber 621 into the inlet opening or inlet openings 640 of the web element channel(s) 611 of the web element family 641 or of the web element families 642, 643, 644 and emerges through the outlet opening or outlet openings 650 from the web element channel(s) 611 and reaches the second chamber 622. The heat transfer fluid flows through the second chamber 622 to the inlet opening(s) 640, which open into the web element channel(s) 612 of the web element(s) 610 of the web element family 651 and/or of the web element family 652, 653, 654, which extend from the second Chamber 622 extend to the third chamber 623.

From the third chamber 623, the heat transfer fluid enters the inlet opening or inlet openings 640 of the web element channel(s) 611 of the web element family 641 or the web element families 642, 643, 644 and exits through the outlet opening or outlet openings 650 from the web element channel(s) 611 and reaches the fourth chamber 624. The heat transfer fluid flows through the fourth chamber 624 to the inlet opening(s) 640, which open into the web element channel(s) 612 of the web element(s) 610 of the web element family 651 and/or of the web element family 652, 653, 654, which extend from the fourth Chamber 624 extend to the fifth chamber 625.

From the fifth chamber 625, the heat transfer fluid enters the inlet opening or inlet openings 640 of the web element channel(s) 611 of the web element family 641 or the web element families 642, 643, 644 and exits through the outlet opening or outlet openings 650 from the web element channel(s) 611 and reaches the sixth chamber 626. The heat transfer fluid flows through the sixth chamber 626 to the inlet opening(s) 640, which open into the bar element channel(s) 612 of the bar elements 610 of the bar element family 651 and/or the bar element families 652, 653, 654, which extend from the sixth Chamber 626 extend to the seventh chamber 627.

In the seventh chamber 627 there is an in Figure 8b Outlet opening 630 shown in dashed lines, which is Figure 8b is invisible, through which the heat transfer fluid can escape from the seventh chamber 627 and can leave the heat exchanger.

According to the present exemplary embodiment, there are a plurality of inlet openings 640 on the inner casing element wall, through which the Heat transfer fluid can get into the corresponding web element channels 611 of the web elements 609 and can enter the chambers 622, 623, 624, 625, 626 from there via outlet openings 650 on the inner shell element wall. At their first end 613, the web elements 609 form a fluid-tight connection with the inner casing element wall, which forms one of the boundaries of the second chamber 622, the fourth chamber 624 or the sixth chamber 626. At their second end 614 , the web elements 609 form a fluid-tight connection with the inner casing element wall, which forms one of the boundaries of the first chamber 621 , the third chamber 623 or the fifth chamber 625 .

At their first end 615 , the web elements 610 form a fluid-tight connection with the inner shell element wall, which forms one of the boundaries of the second chamber 622 , the fourth chamber 624 or the sixth chamber 626 . At their second end 616 , the web elements 610 form a fluid-tight connection with the inner casing element wall, which forms one of the boundaries of the first chamber 621 , the third chamber 623 or the fifth chamber 625 .

The heat transfer fluid can therefore not come into contact with the fluid flowing between the web elements 609, 610. The heat exchange between the fluid and the heat transfer fluid thus takes place via the inner jacket element walls of jacket element 602 and via the web element walls of web elements 609, 610 of insert element 603.

The inner shell element wall of the second, fourth or sixth chamber 622, 624, 626 contains one or a plurality of outlet openings 650 for the web element channels 611 of the web elements 609, which are in connection with the first chamber 621, the third chamber 623 or the fifth chamber 635 . The inner shell element wall of the second, fourth or sixth chamber 622, 624, 626 contains one or a plurality of entry openings 640 for the web element channels 612 of the web elements 610, which form the connection with the third chamber 623 or the fifth chamber 635 or the seventh chamber 627 . The second, third, fourth, fifth, sixth chamber 622, 623, 624, 625, 626 thus contains at least one inlet opening 640 and one outlet opening 650 each or a plurality of inlet openings 640 and a plurality of outlet openings 650.

The arrows with the dot-dash lines indicate the flow direction of the heat transfer fluid in the operating state of the heat exchanger. The fluid flows through the jacket element 602 according to FIG Figure 8a in the drawing direction, the heat transfer fluid can cross flow to the fluid, in the chambers also flow in or against the direction of flow of the fluid. The flow of the heat transfer fluid in the direction of the drawing, ie in or against the direction of flow of the fluid, cannot be inferred from this schematic illustration.

as well as in Fig. 1d In each of the exemplary embodiments, partition walls can be provided in the chambers, through which the heat transfer fluid can be at least partially deflected within the chambers.

As in Figure 7b shown, for each of the illustrated exemplary embodiments, more than two sets of web elements can intersect and can also be connected to one another via common connecting elements. The connecting elements can include transverse webs, for example. A bar element can also consist of a plurality of bar element sections. For example, adjacent web element sections can enclose an angle to one another. It would also be possible for the first bar element section and the second bar element section to be connected to one another via a curved section, this variant not being shown in the drawing.

According to each of the preceding exemplary embodiments, the web elements can be connected to the casing element by gluing, soldering, casting, an additive manufacturing process, welding, clamping, shrinking or combinations thereof. Gluing, soldering or welding can be done from the inside and/or from the outside. In particular, the jacket element and the web elements can be formed in one piece.

According to one exemplary embodiment, the web element channel can run without kinks. According to one embodiment, the web element channel can merge into the chamber without kinks.

The web element channels in the web elements extend from the first end to the second end of the web element, which directly adjoins the inner wall of the shell element. According to one exemplary embodiment, there is an opening in the jacket element, which opening can be designed as an inlet opening or outlet opening. The opening has at least the same cross-sectional area as the cross-sectional area of the web element channel adjoining the opening.

At least part of the web elements thus extends over the entire width dimension or the or the average diameter of the casing element. The mean diameter corresponds to the inner diameter of the jacket element when the jacket element is designed as a circular tube. The mean diameter for a square Shell element is defined as its perimeter / n (pi), so it is an equivalent diameter. In particular, the length of the bar element channel can be at least 10% greater than the mean diameter when the bar element channel crosses the central axis. The length of this web element channel can in particular be at least 20% greater than the mean diameter, particularly preferably at least 30% greater than the mean diameter.

The dimensions of a bar element are determined by its length, width and thickness. The length of the bar member is measured from the first end of the bar member to the second end of the bar member. The length of the bar element channel essentially corresponds to the length of the bar element.

The width of the web element is essentially measured transversely to the direction of flow. That is, the width extends substantially in a plane normal to the length of the bar member and showing the cross section of the bar member. The cross section of the web element is characterized by its width and its thickness. The length of at least the longest web element is at least 5 times as great as its width.

The width of the web element is 0.5 to 5 times its thickness, advantageously 0.75 to 3 times its thickness. If the width of the web element is 1 to 2 times as large as its thickness, a particularly preferred range results for which particularly good cross-mixing can be achieved. The width of the web member is defined as the normal distance extending from the first edge and the second edge of the web member on the upstream side. The width of the bar element on the inflow side can differ from the width measured on the outflow side of the bar element.

Edge is understood to mean the edge of the bar element against which the fluid flows and around which it extends essentially parallel to the length of the bar element. The thickness of the web element can be variable. The minimum thickness is less than 75% and advantageously less than 50% less than the maximum thickness. The variations can be caused, for example, by ribs, indentations, knobs, wedge-shaped webs or some other unevenness.

The web element can be characterized in that flat surfaces, convex or concave surfaces are present in the direction of flow, which offer a contact surface for the flowing fluid. These surfaces aligned in the direction of flow cause an increased Outflow resistance, especially in comparison with a tubular element, which can result in improved heat transfer.

The web element channel, which runs inside the web element, preferably has an inner diameter which corresponds to a maximum of 75% of the thickness of the web element. In principle, a plurality of bar element channels running essentially parallel can also be contained in a bar element.

The transition from at least one of the first and second ends of the web element to the casing element advantageously takes place without a gap. According to one exemplary embodiment, the web elements and the casing element therefore consist of a single component, which is preferably produced by a casting process. A smooth transition from the web element to the jacket element is characteristic of the property that the transition is gap-free. In particular, curves can be provided at the edges in the transition area from the web element to the jacket element, so that the flow of the castable material is not impaired during the production process.

The bar element channels run inside the bar elements, so that there is no connection between the channels inside the bar elements and the space surrounding the bar elements.

In a casting process, a monolithic structure is produced, at least in segments, consisting of groups of web elements arranged at an angle other than zero relative to the main flow direction and a jacket element which is firmly connected to at least some of the web elements and which can be designed as a jacket tube. Instead of a casting process, an additive manufacturing process can also be used.

Alternatively, there is also the possibility that the openings of the jacket element match the outer contour of the web element. According to this exemplary embodiment, the web element can be pushed through the opening of the casing element and thus positioned in the interior of the casing element. According to this exemplary embodiment, the web element can be connected to the casing element by gluing, soldering, welding, clamping, pressing in, or shrinking.

The web element channels for the heat transfer fluid in the web elements can be produced by the casting process described earlier or an additive manufacturing process, but also by subsequent processing such as eroding or drilling.

A heat transfer fluid can include any liquid, such as water or oils, but also a gas, such as air.

The web elements can be arranged at an angle of approximately 25 to 75 degrees, in particular at an angle of approximately 30 to 60 degrees, to the main direction of flow. The bar elements can form groups of bar elements, it being possible for the bar elements of each group of bar elements to be arranged parallel to one another. The bar elements of a group of bar elements can be located in a common group level. According to one embodiment, the first and second group levels intersect. According to a further exemplary embodiment, a web element of the first set of web elements adjoins a web element of the second set of web elements. Accordingly, according to this exemplary embodiment, adjacent bar elements have a different orientation, since they belong to different groups of bar elements.

According to one exemplary embodiment, adjacent bar elements intersect, since an improved heat exchange can be achieved in this way. The angle between two crossing web elements is advantageously 25 to 75 degrees. Any number of bar elements can be arranged next to each other in bar elements. The set of web elements is characterized in that the center axes of all web elements span the same or essentially the same group level. In particular, 2 to 20 bar elements, particularly preferably 4 to 12 bar elements, are arranged in parallel in a group of bar elements.

Any number of groups of web elements can be arranged one behind the other, seen in the main flow direction. The rows of web elements arranged one behind the other are advantageously arranged in such a way that they overlap in order to accommodate as much active heat exchange surface as possible in a small apparatus volume. Overlapping means that at least some of the web elements of a first set of web elements and some of the web elements of a subsequent set of web elements and/or a preceding set of web elements are arranged in the same pipe section, seen in the main flow direction. The projection of the length of the web element on the longitudinal axis gives a length L1 and the projection of the overlapping part of the web elements of the adjacent set of web elements on the longitudinal axis gives a length L2, where L2 is less than L1 and L2 is greater than 0. The tube section under consideration is defined in such a way that it has the length L1, ie it extends from a centrally arranged web element from its first end to its second end in the projection onto the longitudinal axis.

Since the mixing effect in identically aligned rows of web elements arranged one behind the other only takes place in one plane, after a certain number of rows of web elements the alignment can be changed such that the rows of web elements are advantageously offset from one another. In particular, two up to and including 20 rows of web elements are provided, particularly preferably 4 up to and including 8 rows of web elements. The displacement between the gangs of web elements that are aligned in the same way is advantageously carried out by an angle of 80 to 100 degrees. This means that the second set of web elements is aligned around the longitudinal axis at an angle of 80 to 100 degrees in relation to the first set of web elements.

In addition to the previously described sets of web elements of crossing web elements, sets of web elements can also be arranged, especially in the end area of parallel web element sets aligned in the same way, which contain web elements that only extend from the inner wall of the casing element to the crossing line with the other set of web elements. These bar element groups are referred to below as half intersecting bar element groups. These bar element groups lead to an additional increase in mixing performance. Due to the better mixing effect and the additional heat conduction effects of the web element material, the heat exchange is additionally increased.

According to one embodiment, the web elements can form a first and a second set of web elements. Each of the first and second families of web elements can span a first or second group level. In particular, the first group level of the first set of web elements can intersect with the second group level of the second set of web elements in such a way that a common crossing line is formed, which has an intersection with the longitudinal axis or runs essentially transversely to the longitudinal axis and/or in a normal plane to the crossing line, which contains the longitudinal axis, has a minimum distance from the longitudinal axis. According to one exemplary embodiment, at least one group of web elements can be provided, which extends essentially up to the crossing line.

The web elements in a first and second family of web elements may touch one another or have gaps between them. It is also possible to connect the intermediate spaces with connecting webs arranged transversely to the fluid flow direction.

Heat transfer fluid can also flow through different sections or segments of the heat exchanger through separate jacket channels, so that the heat exchanger contains different sections or segments through which heat transfer fluid of different temperatures can flow. This allows a different temperature control in the individual segments. It has been shown that for high heat transfer in a small apparatus volume with jacket element diameters of 60 mm and more, the heat transfer fluid should flow through at least half of all web elements.

It has been shown that a casting method, an additive manufacturing method, a soldering method, an adhesive method, a shrinking method, a clamping method and a welding method can be cost-effective manufacturing methods for bar elements and a jacket element monolithically connected to the bar elements without any gaps. The insert element, comprising the sets of web elements with the corresponding web elements, can be manufactured in one piece. Alternatively, the insert element can consist of individual segments that are subsequently connected, for example by welding or screwed flange connections or by bracing. Furthermore, the outer geometry of the bar elements and the bar element geometry as well as the geometry of the bar element channels for the heat transfer fluid can be easily decoupled for a welding process as well as for a casting process. For example, rectangular profiles can advantageously be used for the outer geometry of the bar elements, and the bar element channel geometry can advantageously be selected as a round cross section, ie in particular a circular or oval cross section. Therefore, web elements with an ideal profile for cross-mixing and/or high inherent strength can be produced for large maximum fluid pressures. It has been shown that the bar element channels for the heat transfer fluid in the bar elements are advantageously produced after the casting process by eroding and even more advantageously by drilling, so that bar element channels with small diameters can also be produced.

It has also been shown that with the array of web elements according to the invention and specifically with arrays of web elements in which adjacent web elements intersect and/or specifically with overlapping groups of web elements, very good heat transfer occurs and/or mixing power can be generated. In particular, the arrangement of a second set of web elements, which is offset by 80 to 100 degrees to the first set of web elements, can be beneficial for good heat transfer. Surprisingly, it has also been shown that a further improvement in the heat transfer and/or the mixing performance can be achieved specifically by attaching additional chambers and specifically in the case of viscous fluids.

The heat transfer and/or the mixing performance in the vicinity of the inner wall of the jacket element is also significantly improved by the direct transition of the web elements into the jacket element, since boundary layers of the flowable medium located on the inner wall are also involved in achieving optimal heat transfer or a homogeneous mixture . In particular, not only an optimal renewal of the boundary layers between the fluid and the jacket element, but also between the fluid and the web element surface can be generated. Optimal boundary layer renewal therefore leads to optimal use of the heat exchange surface. The optimal use of the heat exchange surface also means that the heat exchanger for a given cooling or heating task can be built with an even smaller apparatus volume and with a lower pressure loss.

Thanks to the optimized heat transfer, the heat exchanger according to the invention shows a very narrow residence time spectrum of the flowable medium to be heated or cooled. As a result, deposits or decomposition of fluid can be prevented in the best possible way. For cooling tasks that involve the cooling of a viscous fluid, such as a polymer, a very low melt temperature close to the glass transition point can be achieved thanks to the optimal renewal of the boundary layers. This in particular avoids solidified polymer being deposited on the heat exchange surfaces. The direct transition of the individual web elements into the jacket element and the use of the chambers for the heat transfer fluid that covers as much area as possible also leads to a stable construction that is also suitable for operation with high fluid operating pressures. As a result, the heat exchanger according to the invention can be built very compactly, especially for operation with viscous fluids. The heat exchanger is basically suitable for mixing and cooling or heating any free-flowing media such as liquids and gases, but especially for viscous and very viscous fluids such as polymers.

The jacket element and the insert element can contain castable or weldable materials, for example metals, ceramics, plastics or combinations of these materials can be used.

A method for producing a heat exchanger, which contains an insert element and a shell element, wherein the insert element has at least one web element arranged at an angle other than zero relative to the main flow direction and a shell element firmly connected to the web element, comprises the following method steps. The web element and the insert shell element are produced by an adhesive method, a soldering method, a casting method, an additive manufacturing method, a welding method, a clamping method or a shrink-fitting method or combinations thereof. The bar element contains a bar element channel, which is produced by the casting process or an additive manufacturing process together with the insert casing element or is produced in a further work step by means of a drilling process or an eroding process.

Between the insert element and the jacket element, as in EP3489603 A1 described, intermediate jacket element can be arranged, which contains a first intermediate jacket element channel and a second intermediate jacket element channel, the intermediate jacket element being positioned in the jacket element and the insert element being positioned in the intermediate jacket element in such a way that the heat transfer fluid can flow from the jacket channel through the first intermediate jacket element channel into the web element channel, the web element channel flow through and can flow from the web element channel through the second intermediate jacket element channel into the jacket channel.

The use of an intermediate shell member has several advantages. In this way, the insert element can be made significantly thinner and lighter. A different material, for example a higher quality material, can therefore be used for the insert element than for the intermediate shell element. In particular, the insert element can contain a material that has high thermal conductivity or high resistance to chemicals, for example corrosion resistance. The insert element can be produced in one piece together with the web elements by an additive manufacturing process or a casting process. Since the production of the insert element is very complex, it can be kept in stock as a semi-finished product and the intermediate casing element can be adapted to the required wall thickness depending on the application and the nominal pressure become. The jacket element, which surrounds the intermediate jacket element, can be designed as a further double jacket, through which the heat transfer fluid flows in the operating state. The heat transfer fluid passes through the openings in the jacket element and in the intermediate jacket element as well as in the insert jacket element to at least one of the bar elements, so that it can flow through the bar element or elements.

The invention is not limited to the present exemplary embodiments. The bar elements can differ in their number and in their dimensions. Furthermore, the number of web element channels in the web elements can differ depending on the required heat requirement for the heat transfer. The angle of inclination which the groups or groups of web elements enclose to the longitudinal axis can also vary depending on the application. More than two insert elements can also be arranged one behind the other.

It is obvious to a person skilled in the art that many further modifications are possible in addition to the described embodiments without departing from the inventive concept. The subject of the invention is therefore not limited by the foregoing description and is to be determined by the scope of protection which is defined by the claims. For the interpretation of the claims or the description, the broadest possible reading of the claims is decisive. In particular, the terms "comprising" or "include" should be construed as referring to elements, components or steps in a non-exclusive sense, thereby indicating that the elements, components or steps may be present or used that they can be combined with other elements, components or steps that are not explicitly mentioned. Where the claims relate to an element or component from a group which may consist of A, B, C... N elements or components, such language should be interpreted as requiring only a single element of that group, and not a combination of A and N, B and N, or any other combination of two or more members or components of this group.
