Description

Technical Field

[0001] The invention relates to an adapter for cooling or heating or temperature regulation of a sensor. Background Art

[0002] Sensors detect the physical properties of fluid media in different technical fields such as industry or scientific research. The physical properties of fluid media include, for example, pressure, temperature, pH value, viscosity, compressibility or flow rate. Many of these properties are temperature-dependent.

[0003] An important property is the pressure of the fluid medium, but the invention is by no means limited thereto. In the following, the fluid medium whose properties are determined is referred to as measurement medium.

[0004] The measuring medium is a fluid medium in a gaseous or liquid aggregate state or a mixture of a gaseous and liquid aggregate state. The measuring medium can be, for example, a gas or a liquid. For example, the fuel-gas mixture in the combustion chamber of an internal combustion engine or the exhaust gas formed after at least partial combustion of the fuel is also a fluid medium. The measuring medium can also be the working medium in a compressor, such as a heat pump or a cooling compressor. The measuring medium can also be a gas, such as an inert gas or hydrogen.

[0005] In many cases, the measured medium has a high temperature of 200°C or above or a low temperature of 0°C or below.

[0006] In addition, the measured medium may also be corrosive.

[0007] However, sensors for determining at least one physical property of a measured medium are sensitive to temperatures that are too high or too low. Therefore, temperatures that are too high or too low can distort the measurement results due to the temperature dependence of the measuring element of the sensor. As a result, the physical property may not be determined with high accuracy, in particular in the case of temperature changes in the measured medium. Excessively high temperatures can also damage the sensor. Thus, for example, in some piezoelectric materials, such as those used as measuring elements in pressure sensors, irreversible changes occur at temperatures above 300 ° C. On the other hand, if the temperature is too low, the material used in the sensor may become brittle. This can lead to cracking and damage to the sensor.

[0008] Patent document CH700534A1 discloses a sensor surrounded by a housing for cooling the sensor. The housing has an adapter for cooling the pressure sensor. The adapter has an input pipeline and an exhaust pipeline, which are respectively connected to the cavity. The fluid cooling medium flows from the input pipeline to the exhaust pipeline via the cavity. The adapter has a recess formed along the longitudinal axis for accommodating the pressure sensor. The cavity radially surrounds the recess.

[0009] The known adapters have the disadvantage that they have a significant impact on the structural dimensions of the sensor, which is temperature-regulated by the adapter. The assembly of adapter and sensor, hereinafter referred to as temperature-regulating assembly, requires a larger measuring aperture than a single sensor.

[0010] In many applications, the space around the hole for pressure measurement is narrow. The diameter of the hole itself is often also limited. Adapters that are traditionally made by cutting manufacturing processes and consist of turned and milled parts have a relatively large construction space. Therefore, relatively large, stable elements must be provided for the connection between the components. Even with traditional manufacturing methods, elements for increasing stability cannot be simply placed arbitrarily in the adapter. This results in relatively large adapters.

[0011] The adapter usually has a temperature regulation capacity which depends on the pressure loss between the inlet and outlet and the pressure-dependent flow rate limited thereby. The more efficient the transfer of thermal energy between the temperature regulation medium and the adapter, the better the temperature regulation capacity. The pressure loss in turn depends greatly on the geometry of the cavity and the cross-sections of the inlet and outlet. Until now, it has been difficult to achieve an optimal cooling / heating performance for every available installation space. Summary of the invention

[0012] The object of the present invention is to protect the sensor from high or low temperatures by means of an adapter and to improve the adapter so as to reduce the above mentioned disadvantages. Another object of the present invention is to manufacture the adapter as economically as possible.

[0013] The above objectives are achieved through the technical solution according to the present invention.

[0014] The present invention relates to an adapter for cooling or heating or temperature regulation of a pressure sensor. The term "cooling" refers to the process of discharging heat-generated energy (also called thermal energy or heat) from an adapter or from a sensor arranged in the adapter. The heat in the sensor is thereby removed. The term "heating" refers to the process of supplying heat-generated energy to an adapter or a sensor arranged in the adapter. The term "temperature regulation" refers to the process of keeping the temperature of an adapter or a sensor arranged in the adapter constant. Heat is removed or supplied to the adapter depending on the temperature.

[0015] In the following, the terms temperature control or temperature regulation are used for simplicity. However, this also means cooling or heating.

[0016] The adapter has at least one input line. The adapter has at least one discharge line. The input line and the discharge line are lines for conducting a fluid temperature regulating medium (referred to as temperature regulating medium). The input line and the discharge line are designed to be connected to a device, for example, to a cooling device, a heating device or a temperature regulating device. The temperature regulating medium can be guided from the device through the input line and guided back to the device by the discharge line. The adapter also has at least one cavity. At least one input line and at least one discharge line are connected to at least one cavity so that the fluid temperature regulating medium can flow from the input line through the cavity to the discharge line.

[0017] When in use, the adapter is inserted into a hole in the device, the so-called measuring hole. The measured medium is located inside the device.

[0018] The adapter has a recess formed along the longitudinal axis for accommodating the sensor. The recess has a first end. When the adapter is in use, the first end of the recess faces the measured medium. The recess also has a second end. The second end usually faces a space with normal pressure. Usually, a sensor, such as a pressure sensor, can be inserted into the adapter through the second end. The sensor is arranged in the recess of the adapter in a thermally conductive connection with the adapter. Therefore, the adapter is arranged between the measuring hole and the sensor.

[0019] Fluid temperature regulating medium refers to liquid or gas or gas-liquid mixture. Fluid temperature regulating medium includes, for example, oil, liquid sodium, water, liquid with a certain percentage of glycerol or ethylene glycol or ethanol or propylene glycol, or other coolants, nitrogen, air, inert gas and other suitable cooling liquids. The temperature regulating medium can obtain the target temperature through the device. Alternatively, the device can also extract a certain amount of heat energy from the temperature regulating medium or add a certain amount of heat energy to the temperature regulating medium.

[0020] For example, in the above-mentioned patent document CH700534A1, the adapter is used as a cooling adapter. In the above-mentioned disclosure, the pressure of the thermal measurement medium is determined, more precisely the discharge pressure, the combustion chamber pressure, the combustion chamber pressure and the turbine pressure. The adapter is designed to be connected to a cooling device. Water is used as the temperature regulating medium.

[0021] Adapters are known as heating adapters, which detect, for example, the pressure of a refrigerator, more precisely the pressure in the compressor of the refrigerator. A temperature control medium flows in the cavity of the adapter. The temperature control medium should bring the adapter and the sensor arranged in the recess of the adapter to a higher temperature than the cold measuring medium. The sensor is thus connected to the adapter in a thermally conductive manner.

[0022] The cavity of the adapter is designed so that a temperature control medium can flow around the recess. Capable of flowing around can be understood here as a cavity projected onto a plane perpendicular to the longitudinal axis that surrounds the longitudinal axis by 360°. For example, the cavity can extend around the longitudinal axis as two spiral tubes offset from each other, which are connected to each other at the first end of the adapter. Therefore, the cavity does not necessarily have to completely surround the recess in a plane perpendicular to the longitudinal axis.

[0023] According to the invention, the adapter is constructed in one piece. In this case, one piece means that the adapter is made of one piece of raw material. Therefore, the one-piece adapter is not made by joining together a plurality of semi-finished products or a plurality of workpieces. This has the advantage that no adjustment is required for the different workpieces during the manufacturing process of the adapter. This can avoid waste caused by improper adjustment.

[0024] Preferably, the adapter is welded and soldered Made of ground.

[0025] Non-fusion welded adapters are adapters that do not have a weld seam that closes the adapter. For example, pipes are often made of bent rectangular metal sheets, one side of which is bent together with the opposite side and provided with a weld seam. One-piece adapters do not contain such a weld seam. This is advantageous, since weld seams are susceptible to corrosion and can lead to material fatigue, for example due to so-called hydrogen embrittlement. The disadvantage of weld seams and fusion welding is that due to the welding process of two solid surfaces, in particular with temperature changes in the surrounding material, mechanical stresses often occur thereon. Under the effect of mechanical and / or thermal stresses, cracks may form and ultimately lead to failure of the welded adapter. The same applies to brazed connections. Non-fusion welded and non-brazed adapters are therefore more resistant than adapters with welded connections.

[0026] Preferably, the adapter is manufactured using an additive manufacturing process. An additive manufacturing process is characterized in that the part to be manufactured is manufactured in layers by adding at least one material. In this context, the part to be manufactured is an adapter. Additive manufacturing processes (also called 3D printing technology or 3D printing) usually involve joining materials together layer by layer in order to generate components of a workpiece based on 3D model data. In some additive manufacturing processes, the part to be produced is manufactured directly in all three spatial directions. In most cases, however, manufacturing is carried out in layers, wherein first a layer of the part is manufactured along the two main spatial directions. By adding more layers along a third spatial direction, the part can be manufactured in three dimensions.

[0027] Additive manufacturing processes, also known as generative manufacturing processes, are described in the standard DIN EN ISO 52900: 2022-03 and in Chapter 3 of the following publication: acatech - Deutsche Akademie der Technikwissenschaften, Nationale Akademie der Wissenschaften Leopoldina, Union der deutschen Akademien der Wissenschaften (Hrsg.) (2016): "Additive Manufacturing", Munich, ISBN: 978-3-8047-3676-4 (English version: acatech - National Academy of Science and Engineering, German National Academy of Sciences Leopoldina, Union of the German Academies of Sciences and Humanities (Editors) (2017): "Additive Manufacturing", Munich, ISBN: 978-3-8047-3677-1).

[0028] Known additive manufacturing processes include: fused deposition modeling (FDM), also known as fused deposition modeling (FDM) or fused layered manufacturing / modeling (FLM); bond printing (3DP); layered lamination (LOM, laminated object modeling), also known as layered lamination manufacturing (LLM) or thin film lamination; stereolithography (SLA, STL); resin printing (PJM); plastic laser sintering (SLS, selective laser sintering), or also known as polymer laser melting.

[0029] Additive manufacturing processes based on a powder bed are particularly suitable for metallic materials. Here, the material is applied as a powder layer and then selectively melted under heat supply. After the subsequent solidification, the excess, unmelted material is removed. Examples of known additive manufacturing processes based on a powder bed for metallic materials are laser beam melting (SLM, Selective Laser Melting), or direct metal laser sintering (DMLS), or LaserCUSING, or laser metal melting (LMF), or direct metal printing (DMP), or laser beam melting (LBM), or direct metal laser melting. As an alternative to laser heat input, electron beam melting (EBM, Electron Beam Melting) is also known.

[0030] Other known additive manufacturing processes suitable for metal materials include: selectively directing powdered material as a gas flow to a specific location and melting it, such as additive cladding (LMD, Laser Metal Deposition), or direct metal deposition (DMD), or laser engineered net shaping (Laser Engineered Net Shaping, LENS) or electron beam-based additive manufacturing (EBAM).

[0031] The known screen printing method is particularly suitable for graphite and is also an additive manufacturing process. Thus, a green body made of graphite or ceramic material can first be additively manufactured and then subsequently sintered.

[0032] However, due to the rapid development in the field of additive manufacturing processes, other additive manufacturing processes may also be considered.

[0033] Compared to conventional adapters manufactured by machining manufacturing methods, adapters manufactured by additive manufacturing processes are particularly advantageous because the cavity can be shaped without being restricted by the manufacturing method. Therefore, the cavity can have complex geometries. For example, elements for increasing stability, such as rods or bridges between the cavity walls, can be easily placed at suitable locations. As a result, the walls of the adapter can be made thinner. As a result, the cavity can be enlarged. Alternatively, with the same cavity volume, the adapter can be made smaller than with conventional adapters. Here, the cooling / heating performance of the adapter is exponentially related to the wall thickness between the cavity and the recess for the sensor.

[0034] Instead of the oval or circular shape of the cavity of a conventional adapter disclosed, for example, in patent document CH700534A1, the cavity can be formed in a complex manner and designed for optimized cooling / heating. Therefore, only cavities with straight cooling channels, i.e. straight holes, can be realized in a one-piece conventional component. The adapter produced by the additive manufacturing process can, for example, have one or more spiral or arc-shaped cooling channels as cavities. The channel can also be simply divided into a plurality of sub-channels, or a plurality of sub-channels can be combined into one channel. Of course, the cavity can also have an oval or circular shape.

[0035] In the case of pressure sensors, the sensor can be placed closer to the front due to the smaller installation space of the adapter. This results in better cooling of the adapter produced using additive manufacturing. In addition, the supply channel (the so-called pressure connection) for supplying the measured medium to the pressure sensor can be shorter, which has a positive effect on the limit frequency of the pipe vibrations that usually occur in the supply channel. Pipe vibrations are described by the known Helmholtz resonator theory and interfere with the measurement signal, especially when rapid pressure changes are to be determined.

[0036] Compared to conventional adapters, the adapters manufactured in one piece using an additive manufacturing process are characterized by low manufacturing costs, since many work steps such as adjustment before assembly, mounting and welding are omitted.

[0037] Furthermore, in conventional adapters manufactured by cutting, material can accumulate as residual material. This residual material can be advantageously avoided in adapters manufactured from metal materials using additive manufacturing processes. Powdered metal material is selectively melted or applied. Excess powdered metal material can be removed, collected and reused. This results in lower manufacturing costs.

[0038] Further advantages and aspects of the invention are disclosed in the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0101] Figure 1 An embodiment of a temperature control sensor 1 is shown. The temperature control sensor 1 has an adapter 2 for cooling or heating or temperature control of a pressure sensor 3 and a pressure sensor 3. The adapter 2 has an inlet line 4. The adapter 2 has an outlet line 5. In addition, the adapter 2 has a cavity 6. The inlet line 4 is connected to the cavity 6. The outlet line 5 is also connected to the cavity 6. The connection between the inlet line 4, the outlet line 5 and the cavity 6 is configured so that a fluid temperature control medium 8 can flow from the inlet line 4 via the cavity 6 to the outlet line 5.

[0102] exist Figure 1 In the illustrated embodiment, pipe fittings 17 are respectively connected to the input pipe 4 and the discharge pipe 5 , and the adapter 2 can be connected to a device (not shown) such as a cooling device, a heating device or a temperature regulating device via these pipe fittings.

[0103] The adapter 2 is connected to the pressure sensor 3. The connection can be achieved by a form fit, a material fit or a force fit. The pressure sensor 3 and the adapter 2 are preferably connected to each other by connecting devices 21, 31. Thus, for example, the pressure connector 11 has an external thread 21 as the connecting device 21, and the adapter 2 has a corresponding internal thread 31 as the connecting device 31. A sealing element 16 can be arranged between the adapter 2 and the pressure sensor 3, which prevents the measuring medium 9 from penetrating from the first end 71 of the adapter 2 to the second end 72 of the adapter 2. Alternatively, the connecting devices 21, 31 can also be configured as a bayonet connection. In another embodiment, the connecting devices 21, 31 can also be configured as a welding connection or a soldering connection. The advantage of the welding connection is that no sealing element 16 is required between the pressure sensor 3 and the adapter 2.

[0104] Figure 1 The adapter 2 shown has an optional pressure connection 11 which, during use, faces the measured medium 9 . The pressure connection 11 supplies the measured medium 9 to the pressure sensor 3 .

[0105] The pressure sensor 3 and the adapter 2 are arranged along the longitudinal axis Z. The pressure sensor 3 extends largely along the longitudinal axis Z. A first transverse axis X and a second transverse axis Y extend perpendicularly to the longitudinal axis Z, wherein the first transverse axis X is perpendicular to the second transverse axis Y.

[0106] Figure 2 Shows Figure 1 AA of a portion of an embodiment of a cooled sensor 1 with an adapter 2 and a pressure sensor 3 along the longitudinal axis Z and the second transverse axis Y. For the sake of clarity, the pressure sensor 3 is shown greatly simplified in this and all other sectional views with hatching of the same shape.

[0107] The adapter 2 has a recess 7 formed along the longitudinal axis Z for accommodating the pressure sensor 3. The recess 7 has a first end 71 which, in use, faces the measured medium 9. The recess 7 has a second end 72. For example, the pressure sensor 3 can be inserted into the second end 72 so as to be arranged in the recess 7.

[0108] The pressure sensor 3 generally has a pressure-sensitive surface 32 . The pressure-sensitive surface 32 is generally formed as a membrane 32 .

[0109] The cavity 6 is designed so that the temperature control medium 8 can flow around the recess 7. Figures 1 to 3 In the embodiment, the cavity 6 is configured as a channel 6 that is substantially rotationally symmetrical about the longitudinal axis Z, and has an elliptical cross section near the second end 72 of the adapter 2; and is configured as a channel 6 that is substantially rotationally symmetrical about the longitudinal axis Z, and has an elongated cross section near the first end 71 of the adapter 2. As in Figure 3The basis of Figure 1 As can be seen in the sectional view BB of the partial view of the embodiment of the temperature regulating sensor 1 shown along the longitudinal axis Z and the first transverse axis X, the two channels are connected to form a cavity 6. The part of the cavity 6 in the form of a channel with an elongated cross section is arranged in the pressure connector 11 of the adapter 2 and surrounds the supply channel 12. As a result, the measuring medium 9 located in the supply channel 12 is temperature-adjustable. The other part of the cavity 6 in the form of a channel with an elliptical cross section is arranged at the position of the pressure sensor 3 with respect to the longitudinal axis Z and surrounds the pressure-sensitive part 32 of the pressure sensor 3 located in front with respect to the longitudinal axis Z. It should be noted that it is by no means necessary to divide the cavity 6 into two substantially rotationally symmetrical channels in this way. It is also possible to consider not dividing the channel, dividing it into two channels, or dividing it into two or more than two channels. Those skilled in the art can also set one or more substantially non-rotationally symmetrical channels. These possibilities also belong to part of the present invention.

[0110] It is also conceivable to provide a plurality of supply lines 4 or discharge lines 5 .

[0111] According to the present invention, Figures 1 to 3 The adapter 2 in the embodiment shown is designed in one piece. Therefore, the pipe piece 17 is not a part of the adapter 2 in these embodiments. However, it is also possible to design the pipe piece 17 in one piece with the adapter 2.

[0112] Figure 4 and Figure 5 Shows Figures 1 to 3 A perspective view of the adapter 2 shown. For the sake of clarity, the adapter 2 is shown without the pipe 17, the chamfer, the hexagonal outer edge and the pressure sensor 3. The cavity 6 arranged inside the adapter 2 is indicated by dashed lines. The openings for the inlet line 4 and the outlet line 5 are arranged at the second end 72. In this embodiment of the adapter 2, the cavity 6 is essentially designed as two annular channels surrounding the recess 7, which are connected to the inlet 4 and the outlet 5 on opposite sides with respect to the first transverse axis X.

[0113] In another embodiment described below, Figures 1 to 5 Elements with the same functions in the above embodiments are denoted by the same reference numerals.

[0114] Figure 6 A further embodiment of an adapter 2 is shown, which has a pressure sensor 3 arranged in the adapter 2 . Figure 7 Shown along Figure 6 The schematic section CC of the second transverse axis Y and the longitudinal axis Z in the illustrated view. In addition to the design of the cavity 6, the adapter 2 is also Figures 1 to 3The embodiment of the adapter 2 shown is identical. The cavity 6 has the shape of a tubular channel which extends along two helical lines from a first end 71 of the adapter 2 to a second end 72 of the adapter 2, i.e. a second side 72. The channel starts at Figure 8 4 and extends spirally to the second side 72. Before the second side 72, the channel again spirally extends to the first end 71 and is connected to the discharge line 5 there. The cavity 6 is formed according to the double helical channel. In the projection of the cavity 6 on the plane XY perpendicular to the longitudinal axis Z, the cavity 6 surrounds the longitudinal axis Z by 360°, and therefore surrounds the recess 7 by 360°. The recess 7 can be circumvented by the temperature regulating medium 8 through the cavity 6. Such a cavity 6 is preferably made by the 3D printing process. Conventional manufacturing using cutting methods is almost impossible. Fig. 9 and Fig.10 Shows Figures 6 to 8 2 shows a perspective view of an adapter 2. For the sake of clarity, the adapter 2 is shown without the pipe 17, the chamfers, the hexagonal outer edge and the pressure sensor 3. The cavity 6 arranged inside the adapter 2 is indicated by dashed lines. The openings for the inlet line 4 and the outlet line 5 are arranged at the second end 72. In this illustration, it can be seen that a possible configuration of the cavity 6 is two spiral or helical channels.

[0115] Fig.21 A further embodiment of an adapter 2 is shown, which has a pressure sensor 3 arranged in the adapter 2 . Fig. 22 Shown along Fig.21 A section of a schematic sectional view JJ of the second transverse axis Y and the longitudinal axis Z of the view shown. Fig. 22 The portion of the cavity 6 shown on the left near the first end 71 has the shape of a hollow cylinder. Fig. 22 The portion of the cavity 6 in the lower right center has the shape of a partially hollow cylinder extending less than 180° around the longitudinal axis Z and is connected to the discharge line 5. Fig. 22 The part of the cavity 6 in the upper right center has the shape of a partially hollow cylinder extending less than 180° around the longitudinal axis Z and is connected to the supply line 4. Fig.23 In the cross section KK along the first transverse axis X and the longitudinal axis Z, the connection between the left hollow cylinder and the right hollow cylinder of the supply line 4 is shown. The area between the left hollow cylinder and the two right partial hollow cylinders is also substantially hollow cylindrical, wherein a plurality of stabilizing elements 24 connect the inner wall of the hollow cylinder to the outer edge of the hollow cylinder and divide the hollow cylinder into individual chambers, such as Fig.24As shown. In this case, half of the chamber is connected to the inlet 4 at the second end 72, and the other half of the chamber is connected to the outlet 5 at the second end 72. Therefore, the temperature control medium 8 flows from the second end 72 to the first end 71 in the chamber connected to the inlet 4, and flows from the first end 71 to the second end 72 in the chamber connected to the outlet 5. The cavity 6 surrounds the recess 7 in its projection on the XY plane perpendicular to the longitudinal axis Z. Such an adapter 2 is similar to Figures 1 to 3 The adapter 2 shown is as stable as the one shown, but has a significantly larger cavity wall 61 at which heat exchange between the temperature control medium 8 and the adapter 2 can take place. Fig.25 Shows Figure 21 to Figure 24 A perspective view of the adapter 2 is shown. The cavity 6 arranged inside the adapter 2 is indicated by dashed lines. The openings for the supply line 4 and the discharge line 5 are arranged at the second end 72 .

[0116] Fig.11 Another embodiment of an adapter 2 is shown, which has a pressure sensor 3 arranged in the adapter 2. The adapter 2 additionally has a sleeve 14. The sleeve 14 is configured as a hollow protrusion at the first end 71 of the adapter 2, such as along Fig.11 EE of the schematic cross-section of the second transverse axis Y and the longitudinal axis Z of the view shown. The hollow sleeve 14 extends to the second end 72 of the adapter 2, where it ends in an opening 23, more precisely a contact opening 23. The sleeve 14 is designed to accommodate a temperature probe 15. The temperature probe 15 is not shown for the sake of clarity. The temperature probe 15 is preferably arranged near the first end 71 of the adapter 2. Electrical contact can be easily achieved through the contact opening 23 at the second end 72 of the adapter 2.

[0117] The sleeve 14 is at least partially arranged in the pressure connection 11. When the adapter 2 is used, the sleeve 14 at least partially projects into the measured medium 9 and is sealed gas-tight or pressure-tight relative to the measured medium 9. This has the advantage that the region of the sleeve 14 that projects into the measured medium 9 near the first end 71 of the adapter 2 and is provided for accommodating the temperature probe 15 is at least partially thermally decoupled from the pressure connection 11. As a result, the temperature of the measured medium 9 can be determined and at least the influence of the temperature of the temperature control medium 8 on the temperature probe 15 can be reduced.

[0118] The sleeve 14 may affect the geometry of the cavity 6, such as Fig.12 In this sectional view EE, the cavity 6 is slightly narrowed at the location of the sleeve 14. Advantageously, this adaptation of the geometry can be easily realized by 3D printing. In another sectional view FF along the longitudinal axis Z and the first transverse axis X, the cavity 6 in this plane is slightly narrowed. Figure 3 The cavities 6 in the illustrated embodiments are substantially identical.

[0119] Fig.14 and Fig.15 Shows Figures 11 to 13 1 is a perspective view of the adapter 2 shown in FIG. 2 . For the sake of clarity, the adapter 2 is shown without the tube 17 , the chamfers, the hexagonal outer edge and the pressure sensor 3 . The cavity 6 arranged inside the adapter 2 is indicated by dashed lines. The inner hollow sleeve 14 is partially indicated by dashed lines. The contact opening 23 is at Fig.15 The openings for the inlet line 4 and the outlet line 5 are arranged at the second end 72. In this embodiment of the adapter 2, the cavity 6 is mainly configured as two annular channels surrounding the recess 7, which are connected to the inlet 4 and the outlet 5 on opposite sides with respect to the first transverse axis X.

[0120] Fig.16 FIG. 2 shows another embodiment of an adapter 2 having a pressure sensor 3 arranged in the adapter 2. The adapter 2 additionally has a sleeve 14 in the supply channel 12 of the pressure connection 11, such as Fig.17 Along the Fig.16 As shown in the schematic section view GG of the second transverse axis Y and the longitudinal axis Z of the view shown. The sleeve 14 is designed as a hollow protrusion at the first end 71 of the adapter 2. The hollow sleeve 14 extends from the first end 71 inside the supply channel 12 through the inner wall of the supply channel 12 to the second end 72 of the adapter 2, where it ends in the contact opening 23. The sleeve 14 is designed to accommodate a temperature probe 15. For the sake of clarity, the temperature probe 15 is not shown. The temperature probe 15 is preferably arranged near the first end 71 of the adapter 2. Electrical contact can be easily achieved through the contact opening 23 at the second end 72 of the adapter 2.

[0121] The sleeve 14 is at least partially arranged in the pressure connection 11. When the adapter 2 is used, the sleeve 14 at least partially projects into the measured medium 9 and is sealed gas-tight or pressure-tight relative to the measured medium 9. This has the advantage that the region of the sleeve 14 which projects into the measured medium 9 near the first end 71 of the adapter 2 and is provided for accommodating the temperature probe 15 is at least partially thermally decoupled from the pressure connection 11. As a result, the temperature of the measured medium 9 can be determined and the influence of the temperature of the temperature control medium 8 on the temperature probe 15 can be at least reduced.

[0122] Preferably, in all of the described embodiments of the adapter 2 with the sleeve 14, the sleeve 14 is designed in one piece with the adapter 2. This is advantageous because the sleeve 14 is designed essentially to be sealed with the adapter 2. The disadvantages of the aforementioned weld seam are thereby avoided.

[0123] In accordance with Figures 16 to 18In an embodiment of the present invention, in the manufacture of complex structures, the sleeve 14 can be guided in the adapter 2 in such a way that it has no influence on the geometry of the cavity 6 . Figures 16 to 18 The cavity 6 in the embodiment shown is Figures 1 to 3 The cavities 6 in the embodiments shown are designed identically.

[0124] Fig.19 and Fig. 20 Shows Figures 16 to 18 2 . For the sake of clarity, the adapter 2 is shown without the tube 17 , the chamfers, the hexagonal outer edge and the pressure sensor 3 . The cavity 6 arranged inside the adapter 2 is shown in dashed lines. The inner hollow sleeve 14 is partially shown in dashed lines. The contact opening 23 is Fig. 20 The openings for the inlet line 4 and the outlet line 5 are arranged at the second end 72. In this embodiment of the adapter 2, the cavity 6 is mainly configured as two annular channels surrounding the recess 7, which are connected to the inlet 4 and the outlet 5 on opposite sides with respect to the first transverse axis X.

[0125] All embodiments of the temperature-regulated pressure sensor 1 with the adapter 2 may have one or more further advantageous features. These features do not relate exclusively to the embodiments shown in the figures.

[0126] Preferably, the adapter 2 is made without welding or soldering. Figures 1 to 25 As shown, the adapter 2 itself has no welded or soldered connection. Any possible positive, force-fitting or material-fitting connection of the pipe piece 17 to the adapter 2 in the region of the supply line 4 and / or the discharge line 5 does not conflict with this property of the adapter 2.

[0127] Preferably, the adapter 2 is manufactured using an additive manufacturing process. Figures 1 to 25 The embodiment shown in FIG. 1 shows a complex geometry of the cavity 6. Therefore, the shaping of the cavity 6 is not subject to any restrictions of the manufacturing method. Figures 1 to 3 and Figures 11 to 20 In the embodiment of the present invention, the cavity 6 is constructed in the form of two channels, between which the adapter 2 has a solid material. This complex structure improves the stability of the adapter 2. Figures 6 to 8 The adapter 2 shown cannot be produced in one piece using conventional metal-cutting production methods. In a conventional one-piece component, only cavities 6 with straight channels, ie straight holes, can be realized. Figures 6 to 8 The adapter 2 shown, which is manufactured by an additive manufacturing process, has a plurality of spiral or arc-shaped channels as cavities 6. Figures 1 to 3 as well as Figures 11 to 13The embodiment of the adapter 2 in FIG. 4 has a cavity 6 in the form of a plurality of sub-channels which are separated from the inlet 4 or the outlet 5 or are combined into one channel.

[0128] Furthermore, the adapter 2 is preferably made of a metal material. Metallic materials are advantageous because they generally have good thermal conductivity. Therefore, thermal energy can be well conducted between the pressure sensor 3 and the temperature control medium 8 in the recess 7 through the material of the adapter 2. Therefore, the recess 7 of the adapter 2 should be designed as accurately as possible to ensure good heat transfer. Good heat transfer between the adapter 2 and the pressure sensor 3 also occurs in the area of ​​the connecting devices 21, 31, where the adapter 2 and the pressure sensor 3 are inherently in contact with each other. In the area between the adapter 2 and the pressure sensor 3, a heat conducting paste or the like can be optionally added, which area is sealed by the sealing element 16 to prevent direct contact with the measured medium 9.

[0129] However, fields of application are also conceivable in which the adapter 2 is made of ceramic or plastic. For example, when using the temperature control sensor 1 close to high voltages, the adapter 2 and the pressure sensor 3 as well as the membrane 32 of the pressure sensor 3 are made of plastic, for example a thermoplastic or a thermosetting plastic. Suitable additive manufacturing processes are known to those skilled in the art.

[0130] Preferably, the adapter 2 is made of a material with a thermal conductivity greater than 30 W·(m·K) -1 Made of materials. Greater than 30W·(m·K) -1 The high thermal conductivity of the adapter 2 is advantageous because the adapter 2 connected to the pressure sensor 3 can be effectively supplied or removed with heat. The material is, for example, a pure metal such as copper, aluminum, magnesium, or a metal alloy such as copper alloy, bronze, etc., or graphite. In particular, graphite is easy to obtain, low in cost and has high thermal conductivity.

[0131] It is particularly advantageous if the adapter 2 is made of a material having a melting point above 600° C. and a density below 5 g cm -1 A melting point above 600°C allows use in combination with hot gases, where the temperature of the gas can be above 600°C, since the adapter 2 can be effectively cooled. Below 5 g cm -1 The low density allows the construction of lightweight adapters 2 in applications where weight or inertia plays a major role, such as space flight associated with rocket engines. Suitable materials are, for example, aluminum, magnesium, titanium or graphite (with the exclusion of oxygen), depending on the required temperature resistance.

[0132] It is also particularly advantageous if the adapter 2 is made of a material having a density of less than 5 g cm -1 And the thermal conductivity is greater than 30W·(m·K) -1This combines an advantageous lightweight construction with effective temperature regulation of the pressure sensor 3 .

[0133] Preferably, the adapter 2 is made of a metal material. Metallic materials are advantageous because they generally have good thermal conductivity. Therefore, heat energy can be well conducted between the pressure sensor 3 in the recess 7 and the temperature regulating medium 8 through the material of the adapter 2. The above-mentioned additive manufacturing process is advantageous for the adapter 2 made of a metal material.

[0134] The adapter 2 can also be made of known materials of the pressure sensor 3 or the sensor housing, such as pure metals such as titanium, copper, silver, aluminum, etc., or metal alloys, such as copper alloys or 17-4PH, or 304 or 316L, etc. The materials 17-4PH or 316L (also known as 1.4548 or 1404 steel according to DIN EN 10027, known to those skilled in the art) are particularly advantageous, because pressure sensors usually have a housing made of this material. In this case, the adapter 2 and the pressure sensor 3 have the same thermal expansion when the temperature changes, so that stresses between the adapter 2 and the pressure sensor 3 are avoided. The person skilled in the art selects a suitable material according to the requirements to facilitate the corrosion resistance and thermal conductivity of the adapter 2 and the cost.

[0135] The thermal conductivity of gold and copper is very high, greater than 200W·(m·K) -1 (Watts per meter and Kelvin). Gold and titanium are very corrosion resistant. Aluminum and titanium, as well as magnesium, have a relative density of less than 5 g cm -1 The low density of (grams per cubic centimeter) makes it possible to realize a relatively light adapter 2.

[0136] It is particularly advantageous if the adapter 2 is designed to be seal-free. The cavity 6 is not sealed against the measured medium 9 or against the environment by sealing elements, except for the connection of the inlet 4 to the pipe 17 and the connection of the outlet 5 to the pipe 17. This is advantageous because no additional seals are required and thus also seal failures and possible leaks are avoided.

[0137] It is particularly advantageous to use one of the above-mentioned metal 3D printing methods to produce the adapter 2. Complex geometries of the adapter 2 and the cavity 6 can thus be easily realized from metal materials.

[0138] Preferably, the wall 61 of the cavity 6 (referred to as the cavity wall 61 for short) at least partially has a surface roughness R greater than 10 μm. z Particularly preferably, the cavity wall 61 at least partially has a surface roughness R according to DIN EN ISO 4288. z , in R z =20μm and R z=1000 μm. This microstructure of the cavity wall 61 is advantageous because the roughness of the cavity wall 61 causes eddy currents in the temperature regulating medium 8 flowing through the cavity 6. The eddy currents cause mixing of the temperature regulating medium 8, which enables more heat energy to be removed from or supplied to the adapter 2. It has been confirmed that: compared with the surface roughness R of conventional manufacturing z Compared with adapters with a surface roughness R < 2 μm, the surface roughness R z In R z =20μm and R z = 1000 μm, the heat transfer of the cavity wall 61 is 20% higher. This surface roughness can be directly obtained by 3D printing process or by chemical etching.

[0139] Preferably, a three-dimensional structure 62, such as a porous sponge-like material, is at least partially arranged in the cavity 6. The temperature control medium 8 can flow through the three-dimensional structure 62. Here, the three-dimensional structure 62 causes further eddy flow of the temperature control medium 8 and thus better mixing of the temperature control medium. As a result, the heat energy transfer between the temperature control medium 8 and the cavity wall 61 is further improved.

[0140] Particularly preferably, the three-dimensional structure 62 is constructed as a triplyperiodic minimal surface, abbreviated as TPMS (triplyperiodic minimal surface), such as Figure 26 to Figure 29 As shown. The TPMS structure 62 consists of three-dimensional cells that are usually arranged periodically in space. The mathematical description and possibilities for generating digital CAD drawings required for 3D printing are well known to those skilled in the art, for example in the publication Al-Ketan O, Abu Al-Rub RK. MSLattice: A free software for generating uniform and graded lattices based on triply periodic minimal surfaces. Mat Design Process Comm. 2020.

[0141] In this case, the TPMS structure 62 may be made of a plastic or metal material or graphite. The TPMS structure 62 is at least partially arranged in the cavity 6 . Fig.30 An embodiment of the adapter 2 is shown by way of example, in which a TPMS structure 62 is arranged in the cavity 6. Of course, the arrangement of the TPMS structure 62 is not limited to the embodiment shown.

[0142] Preferably, the TPMS structure 62 is made of the same material as the adapter 2. As a result, stresses between the cavity wall 61 and the TPMS structure 62 can be avoided. The TPMS structure 62 arranged in the cavity 6 further improves the heat transfer between the temperature control medium 8 and the adapter 2. In particular, by determining the dimensions of the individual cells and the cavity 6, the eddy flow level and the resulting pressure loss between the inlet 4 and the outlet 5 can be precisely adjusted. The cooling performance, heating performance or temperature control performance of each structural space of the adapter 2 is thus easily and effectively maximized.

[0143] Preferably, the structure 62 is made in one piece with the adapter 2. This can be achieved in particular in conjunction with a metal 3D printing process. Thus, the TPMS structure 62 can be formed directly with the adapter 2. This allows for an optimal heat transfer between the TPMS structure 62 and the cavity wall 61.

[0144] In particular, the cavity wall 61 is at R z =20μm and R z A surface roughness of between 200 Å and 1000 μm is also advantageous for the surface of the TPMS structure 62 . This ensures further turbulence of the temperature control medium 8 .

[0145] Among the known TPMS structures 62Gyroid, Diamond, Primitive, I-WP, Neovius, S, F-RD and PMY described in the above-mentioned publications, in particular the structure 62Diamond (Schwarz-Diamond) and its sub-variants have proven to be particularly advantageous because they have a larger surface area, which enables good heat transfer and the temperature control medium 8 to be well mixed and flow through it at the same time.

[0146] Particularly preferably, the cavity wall 61 has no edges with a radius of less than 0.1 mm. This has the advantage that no strong local eddies will occur. The eddies of the temperature control medium 8 are thus formed uniformly along the entire flow path.

[0147] In some embodiments, the adapter 2 has a pressure connection 11 for supplying the measuring medium 9 to the recess 7 for the pressure sensor 3. For this purpose, the pressure connection 11 has at least one supply channel 12. The pressure connection 11 can be connected to the measuring hole. In general, the pressure connection 11 is connected to the measuring hole via a connection device 22, for example, via an external thread. Preferably, the pressure connection 11 has a diameter of less than 9 mm. Since thread diameters of in particular M8 and smaller according to DIN 13 or thread diameters of 1 / 4 inch and smaller according to the unified thread standard are widely used as measuring holes, the pressure connection 11 particularly preferably has an M8 external thread or a 1 / 4 inch external thread. The thread specifications include not only standard threads, fine threads, but also ultra-fine threads when necessary. The advantage is that the adapter 2 can be used particularly in narrow situations. Here, the recess 7 is constructed so that it has, for example, an M5 internal thread according to DIN 13 as a connection device 21. A pressure sensor 3, for example, a Kistler 4017 type, having an M5 external thread as a connection device 31 can be inserted into the recess 7.

[0148] The adapter 2 is preferably used together with the pressure sensor 3 for temperature regulation in the temperature regulation assembly 1. The temperature regulation assembly 1 therefore comprises an adapter 2 for cooling or heating or temperature regulation of the pressure sensor 3 and a pressure sensor 3, wherein the pressure sensor 3 is constructed essentially rotationally symmetrically along the pressure sensor longitudinal axis W. The pressure sensor 3 has a pressure-sensitive surface 32, typically in the form of a membrane 32, along the pressure sensor longitudinal axis W at a first end 71. The pressure sensor 3 can be introduced into the recess 7 of the adapter 2, wherein the pressure sensor longitudinal axis W is oriented parallel to the longitudinal axis Z. The pressure sensor 3 and the adapter 2 can be connected in a pressure-tight manner.
