Description

Technical Field

[0001] The present invention relates to the technical field of temperature sensing structures, and in particular to an embedded temperature sensing structure and a temperature measurement method. Background Art

[0002] In recent years, with the advancement of science and technology, the requirements for measuring and sensing equipment have also increased. The accuracy of measuring and sensing equipment directly affects the accuracy of test data. Traditional measuring and sensing equipment, in addition to its inherently poor precision, also suffers from significant measurement errors. In the field of temperature sensing, common contact temperature sensing devices are structurally categorized into two types: bare die and packaged. Bare die sensors measure by attaching the sensor to the measurement area, while packaged sensors are mechanically fixed using a specific adapter structure. However, due to the special packaging structure, applicable structures are limited, and the mechanical connection lacks sealing properties. Patch sensors can only be attached to the wall of a structure, resulting in low measurement accuracy and making them unsuitable for measuring temperatures within sealed structures.

[0003] To this end, an embedded temperature sensor device that can measure the temperature inside a sealed structure has been introduced and is widely used. However, in the prior art, embedded temperature sensor devices generally have two problems:

[0004] 1. The heat transfer efficiency between the temperature sensor and the sealed structure medium in the embedded temperature sensing device is poor, resulting in inaccurate measurement;

[0005] 2. It is inconvenient to disassemble and replace the embedded temperature sensor equipment.

[0006] Therefore, it is an urgent problem for ordinary technicians in this field to produce an embedded temperature sensing device that is accurate in measurement and easy to disassemble and replace. Summary of the Invention

The thermally conductive sleeve is fixedly connected to the support assembly, and the end of the thermally conductive sleeve that contacts the medium in the structure to be measured is in contact with the temperature sensor. By filling the sleeve with copper powder, the heat of the medium in the structure to be measured is transferred to the temperature sensor for temperature measurement.

[0016] In some embodiments, the diameter of the second through hole is consistent with the outer diameter of the temperature measuring probe, and a first abutment portion extends from the inner sidewall of the second through hole toward the center of the second through hole to prevent the temperature measuring probe from sliding up and down;

[0017] A circular boss is extended from one side of the sealing plug close to the clamping rod toward the clamping rod, the outer diameter of the boss is consistent with the outer diameter of the temperature probe, and the end of the clamping rod away from the temperature probe is sleeved on the boss;

[0018] A third through hole is formed on the boss and is communicated with the first through hole. The diameter of the third through hole is smaller than that of the first through hole.

[0019] In some embodiments, a tapered threaded fixing ring is sleeved at the connection between the boss and the clamping rod, and the boss and the clamping rod are fixed by tightening the fixing ring.

[0020] In some embodiments, the end of the clamping rod close to the temperature measuring probe has a multi-petal structure.

[0021] In some embodiments, an internal thread is provided in the middle area of the inner side wall of the support assembly, and an external thread is provided in the corresponding area of the thermal sleeve. The two are fastened together by threads to achieve a first seal.

[0022] In some embodiments, a conical groove is provided at one end of the support assembly away from the structure to be temperature measured;

[0023] The outer side of the heat-conducting sleeve and the area corresponding to the tapered groove are spherical in structure and abut against the tapered groove to achieve a second seal.

[0024] In some embodiments, the support assembly is welded to the edge of the opening of the structure to be temperature measured to achieve a third seal;

[0030] Fixing the thermal sleeve inside the support assembly;

[0031] The temperature sensor is installed inside the heat-conducting sleeve so as to contact the end of the heat-conducting sleeve that contacts the medium in the structure to be temperature measured to perform temperature measurement.

[0032] In some embodiments, the temperature measurement method of the present invention can use any of the above-mentioned embedded temperature measurement sensing structures to measure temperature and be executed according to the above-mentioned steps.

[0033] Compared with the prior art, the embedded temperature sensing structure and temperature measurement method provided by the present invention have all or part of the following beneficial effects:

[0034] The present invention provides an embedded temperature sensing structure in which the end of the thermal sleeve that contacts the medium in the structure to be measured directly contacts the temperature sensor installed within it, resulting in excellent heat conduction and accurate measurement. Furthermore, when replacing the temperature sensor, only the one installed within the thermal sleeve needs to be replaced, making the operation convenient, saving time and cost.

[0035] 2. The present invention provides an embedded temperature sensing structure, in which the support component is connected to the edge of the opening of the temperature-measured structure by welding, and the support component and the thermal sleeve are triple-sealed by threaded fastening, silver welding, and spherical surface, thereby improving the sealing and reliability of the embedded temperature sensing structure and ensuring its long-term use.

[0048] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0049] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0050] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0051] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] As an example, see Figures 1 to 6 An embedded temperature sensing structure suitable for measuring the internal temperature of a sealed structure includes a support assembly 1000 and a temperature measuring assembly 2000. A hole is first opened at the measurement point of the temperature-measured structure 3000. The support assembly 1000 is then fixed to the edge of the hole in the temperature-measured structure 3000, extending through the structure 3000. The support assembly 1000 is preferably made of stainless steel. The temperature measuring assembly 2000 is then inserted into the support assembly 1000, with one end extending into the temperature-measured structure 3000. By inserting the temperature measuring assembly 2000 into the temperature-measured structure 3000, the temperature of the medium in the temperature-measured structure 3000 can be directly measured.

[0054] The temperature measurement assembly 2000 includes a thermal sleeve 2100 and a temperature sensor 2200 mounted within the thermal sleeve 2100. The thermal sleeve 2100 is fixedly connected to the support assembly 1000, and the end of the thermal sleeve 2100 that contacts the medium in the structure 3000 to be measured contacts the temperature sensor 2200. The end transfers heat from the medium in the structure 3000 to the temperature sensor 2200 for temperature measurement.

[0055] In actual production, the thermal sleeve 2100 is preferably made of copper, because copper has excellent thermal conductivity, which can ensure good thermal conductivity between the temperature sensor 2200 and the medium in the temperature-measured structure 3000, thereby improving the measurement accuracy.

[0056] When the temperature sensor 2200 fails or needs to be replaced due to other reasons, it is only necessary to take out the temperature sensor 2200 installed inside the thermal sleeve 2100 and replace it, which is convenient, fast and low-cost.

[0057] In one embodiment, see Figure 1 The temperature sensor 2200 includes a clamping rod 2210, a sealing plug 2220 and a temperature probe 2230, wherein the clamping rod 2210 and the sealing plug 2220 are preferably made of stainless steel. The sealing plug 2220 is connected to the end of the thermal sleeve 2100 away from the structure to be measured 3000, and is used to isolate the temperature probe 2230 from the outside air so that it is not affected by external factors, and the measurement data is more accurate and has a longer service life. One end of the clamping rod 2210 is used to clamp the temperature probe 2230, and the other end is fixedly connected to the sealing plug 2220. The sealing plug 2220 and the clamping rod 2210 are respectively provided with a first through hole 2221 and a second through hole 2211 for the wires of the temperature probe 2230 to pass through.

[0058] During assembly, the sealing plug 2220, clamping rod 2210, and temperature probe 2230 are first mechanically connected and then integrally mounted within the thermal sleeve 2100. This allows the temperature sensor 2200 to be repaired or replaced by simply removing the sealing plug 2220, then the temperature probe 2230, and replacing it with a new one.

[0059] Furthermore, to further enhance the measurement accuracy of the embedded temperature sensing structure provided by the present invention, copper powder is filled into the interior of the thermal sleeve 2100 through the first and second through-holes 2221 and 2211 to increase thermal conductivity and reduce the temperature difference between the temperature probe 2230 and the medium within the temperature-measured structure 3000. After filling, the first through-hole 2221 is sealed to prevent the copper powder from overflowing.

[0060] It is worth noting that the copper powder needs to fill the entire interior of the thermal sleeve 2100. This ensures that copper powder is present at the temperature-measuring end, regardless of the angle and orientation of the embedded temperature sensing structure into the temperature-measuring structure 3000, such as when inserted upside down from below, thereby improving measurement accuracy. In actual production, the first through hole 2221 is preferably sealed with vacuum sealant.

[0061] At this time, the end of the clamping rod 2210 close to the temperature probe 2230 is provided with a plurality of holes for the copper powder to flow out so that the copper powder can fill the entire interior of the thermal sleeve 2100.

[0062] In one embodiment, see Figure 1 and Figure 4 The diameter of the second through hole 2211 is the same as the outer diameter of the temperature probe 2230. The temperature probe 2230 is partially engaged directly into the second through hole 2211, thereby securing the temperature probe 2230 to the clamping rod 2210. Furthermore, a first abutment 2212 extends from the inner sidewall of the second through hole 2211 toward the center of the second through hole 2211, preventing the temperature probe 2230 from sliding up and down and limiting its position.

[0063] Preferably, see Figure 1 、 Figure 4 、 Figure 5 and Figure 6 A circular boss 2222 is extended toward the clamping rod 2210 on one side of the sealing plug 2220 close to the clamping rod 2210. The outer diameter of the boss 2222 is consistent with the outer diameter of the temperature probe 2230. The end of the clamping rod 2210 away from the temperature probe 2230 is sleeved on the boss 2222 to achieve fixation between the sealing plug 2220 and the clamping rod 2210.

[0064] Furthermore, the boss 2222 is provided with a third through-hole 2223, which is connected to the first through-hole 2221 to facilitate filling of the thermal sleeve 2100 with copper powder. Preferably, the diameter of the third through-hole 2223 is smaller than that of the first through-hole 2221. This effectively prevents copper powder from overflowing from the thermal sleeve 2100.

[0065] In actual production, there are many ways to fix the sealing plug 2220 and the clamping rod 2210, such as fixing with bolts, snaps, etc., or they can be directly integrally formed.

[0066] As a further optimization, see Figure 1 A tapered threaded fixing ring 4000 is provided at the connection between the boss 2222 and the clamping rod 2210. By tightening the fixing ring 4000, the connection between the boss 2222 and the clamping rod 2210 can be further strengthened to prevent accidental loosening between the boss 2222 and the clamping rod 2210, thereby improving the reliability of the structure.

[0067] In one embodiment, see Figure 1 A second abutting portion extends from the inner sidewall of the thermal sleeve 2100 corresponding to the sealing plug 2220 to abut the sealing plug 2220. Correspondingly, a third abutting portion extends from the inner sidewall of the thermal sleeve 2100 corresponding to the fixing ring 4000 to abut the fixing ring 4000.

[0068] In one embodiment, see Figure 4The end of the clamping rod 2210 near the temperature probe 2230 is a multi-petal structure 2213, which makes it easier to remove and install the temperature probe 2230. At this time, the gaps between the multi-petal structures 2213 are just enough for the copper powder to flow out, filling the entire interior of the thermal sleeve 2100, eliminating the need for additional holes for the copper powder to flow out.

[0069] In actual production, the number of petals of the multi-petal structure 2213 is not limited, and it can be a three-petal structure or a four-petal structure, etc., all of which are within the protection scope of the present invention.

[0070] Similarly, the clamping rod 2210 is not limited to this structure and can also have other structures. For example, if the clamping rod 2210 is a tube, it can also clamp the temperature probe 2230. When removing the temperature probe 2230, it can be directly plugged in and out, which is also very convenient. Providing several holes in the middle area of the tube for the copper powder to flow out can also ensure that the copper powder fills the entire interior of the thermal sleeve 2100.

[0071] In one embodiment, the support assembly 1000 has internal threads in the middle area of its inner sidewall, while the corresponding area of the thermal sleeve 2100 has external threads. These threads are fastened together to create a primary seal. This threaded connection is simple and convenient for assembly and disassembly. In actual production, fine-pitch threads are preferred for their excellent sealing, ensuring the inherent sealing of the temperature-measured structure 3000 and ensuring proper operation.

[0072] Further, see Figure 1 To facilitate assembly, the end of the thermal sleeve 2100 away from the temperature-measured structure 3000 should partially extend out of the support assembly 1000 so that the assembler can grasp this part during installation, thereby tightening the thermal sleeve 2100 to complete the assembly between the thermal sleeve 2100 and the support assembly 1000.

[0073] See also Figures 1 to 3 Because openings are required to seal the structure and perform temperature measurement, the sealing performance of the sealing structure is compromised, leading to performance degradation. The main leakage points are at the connections between the support assembly 1000 and the structure to be measured 3000, and between the thermal sleeve 2100 and the support assembly 1000. Leakage between the thermal sleeve 2100 and the support assembly 1000 is particularly severe. Therefore, as a further optimization, a conical groove 1001 is provided on the end of the support assembly 1000 away from the structure to be measured 3000. In this case, the outer side of the thermal sleeve 2100, corresponding to the conical groove 1001, is spherical and abuts against the conical groove, achieving a secondary seal.

[0074] In this embodiment, the sealing is achieved by the abutment between the spherical surface and the inclined surface, which has a better sealing effect. Moreover, during the mating process, the thermal sleeve 2100 and the support assembly 1000 are not easily damaged by collision, thereby affecting their sealing performance and service life.

[0075] As a further optimization, see Figure 1 The support component 1000 is welded to the edge of the opening of the temperature-measured structure 3000, and the connection between the end of the support component 1000 away from the temperature-measured structure 3000 and the thermal sleeve 2100 is sealed by silver welding. Because the support component 1000 is made of stainless steel and the thermal sleeve 2100 is made of copper, the silver welding effect between the two is the best and can play a sealing role.

[0076] Sealing the two main leakage points by welding can effectively prevent the leakage of gas, fluid and other media inside the temperature measurement structure 3000, ensuring the performance of the temperature measurement structure 3000 and preventing it from being affected by the temperature measurement opening.

[0077] The connection between the thermal sleeve 2100 and the support assembly 1000 utilizes a triple sealing structure, including threads, spherical surfaces, and silver solder, ensuring strong sealing. The use of metal seals, rather than non-metallic sealing rings, further enhances sealing reliability and ensures the long-term use of the temperature-measured structure 3000 and an embedded temperature sensing structure.

[0078] In one embodiment, the outer wall of the sealing plug 2220 is provided with external threads, and the inner wall of the thermal sleeve 2100 is provided with internal threads at corresponding locations, and the two are fastened together by threads. This makes the connection between the sealing plug 2220 and the thermal sleeve 2100 easier to assemble and disassemble. When the temperature probe 2230 needs to be replaced, the sealing plug 2220 can be unscrewed, the temperature probe 2230 can be removed from the clamping rod 2210, the new temperature probe 2230 can be installed on the clamping rod 2210, and the sealing plug 2220 can be screwed into the thermal sleeve 2100.

[0079] Specifically, see Figure 1 、 Figure 5 and Figure 6 The sealing plug 2220 is provided with a gripping portion 2224 on the side away from the clamping rod 2210. The assembler can use this gripping portion 2224 to rotate the sealing plug 2220, thereby achieving assembly and disassembly between the sealing plug 2220 and the thermal sleeve 2100. Preferably, the gripping portion 2224 is located at the center of the sealing plug, and in this case, the first through hole 2221 passes through the gripping portion 2224.

[0080] Furthermore, the gripping portion 2224 may be in a hexagonal plate-shaped structure, and the assembler can loosen or tighten the sealing plug 2220 by rotating the gripping portion 2224 , thereby achieving disassembly and assembly between the sealing plug 2220 and the thermal sleeve 2100 .

[0081] The present invention provides an embedded temperature sensing structure for measuring the temperature of the medium in pressure vessels and piping structures, ensuring that the temperature measuring probe and the medium in the structure to be measured are separated only by a thermally conductive sleeve. The temperature measuring probe is placed inside the thermally conductive sleeve, which is filled with copper powder for heat conduction. The thermally conductive sleeve is in direct contact with the medium in the structure to be measured. Similarly, the temperature measuring probe and the thermally conductive sleeve are in contact at the same end, so that the difference between the measured temperature of the temperature measuring probe and the temperature of the medium in the structure to be measured is small, and the measurement accuracy is higher. The structure is simple and highly detachable. If the probe is damaged, it can be directly removed and replaced, which is easy to operate. In addition, the parts where gas or fluid leakage may occur are sealed to ensure the performance of the structure to be measured.

[0082] The present invention also provides a temperature measurement method, comprising the following steps:

[0083] Fix the support assembly 1000 to the edge of the opening of the temperature-measured structure 3000 so that it is connected to the interior of the temperature-measured structure 3000;

[0084] Fix the thermal sleeve 2100 inside the support assembly 1000;

[0085] The temperature sensor 2200 is installed inside the thermal sleeve 2100 so as to contact the end of the thermal sleeve 2100 that contacts the medium in the structure 3000 to be measured for temperature measurement.

[0086] Specifically, the embedded temperature sensing structure of any of the above-described embodiments can be used for temperature measurement. First, a hole is opened at the measurement point in a sealed pipeline or container to be measured. The support assembly 1000 is welded to the hole, and the thermal sleeve 2100 is screwed onto the support assembly 1000 via silver soldering. After the clamping rod 2210, sealing plug 2220, temperature probe 2230, and retaining ring 4000 are assembled, the sealing plug 2220 and thermal sleeve 2100 are screwed together to securely connect them. The temperature probe 2230 and thermal sleeve 2100 are then brought into contact with the end of the thermal sleeve 2100 that contacts the medium in the structure 3000 to be measured. Copper powder is then filled into the thermal sleeve 2100 until it completely fills the entire structure. Finally, the first through-hole 2221 is sealed, and measurement is performed.

[0087] If the temperature probe 2230 needs to be replaced later, unscrew the clamping rod 2210, sealing plug 2220, temperature probe 2230 and fixing ring 4000 assembled as one from the inside of the thermal sleeve 2100, then replace the temperature probe 2230, assemble the replaced temperature probe 2230 and the clamping rod 2210, sealing plug 2220 and fixing ring 4000 together, and re-fix them to the inside of the thermal sleeve 2100 for measurement.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
