Description

Technical Field

[0001] This utility model relates to the field of pipeline temperature measurement technology, and in particular to a heat-conducting fixing component for a hot and cold carbon meter and a temperature measuring device including the heat-conducting fixing component. Background Technology

[0002] A cold / hot carbon meter is a metering device that detects carbon emissions at the cooling and heating ends. These devices are commonly used in energy metering systems, especially in applications involving heat exchange, such as building automation, environmental monitoring, and heating and cooling systems. They include temperature sensors for measuring the temperature of the hot and cold media and are a key component of the energy metering system. The temperature sensor typically operates within a temperature range of -40°C to +125°C. To ensure proper operation, the device must withstand complex environmental temperatures and maintain accuracy and reliability.

[0003] There are two existing temperature measurement methods. The first method involves installing the water pipe temperature sensor on the surface of the water pipe and fixing it in a suitable position using a fixing clamp or other fixing device. The second method involves installing the water pipe temperature sensor inside the water pipe and embedding the sensor inside the water pipe through special designs or structures such as opening holes or grooves.

[0004] Existing temperature measurement methods face some problems in practical applications. For example, when using the first method, the water pipe temperature sensor is directly exposed and fixed to the surface of the water pipe. To ensure measurement accuracy, the water pipe temperature sensor is directly attached to the pipe wall during installation. This process requires multiple adjustments to the fixing and attachment states. Although the installation steps and structure of the first method are relatively simple, the water pipe temperature sensor directly attached to the pipe wall is easily affected by environmental factors (such as direct sunlight and humidity changes). Furthermore, under extreme temperature conditions, the water pipe temperature sensor may experience temperature shift, leading to measurement errors. Additionally, in cases of rapid temperature changes, the response time of the water pipe temperature sensor is delayed, failing to reflect the actual temperature changes in a timely manner.

[0005] When using the second temperature measurement method, the water pipe temperature sensor needs to be pre-installed in the pipe to be measured. It is inserted into the water pipe directly into contact with the internal fluid using a screw thread or plug-in method. The water pipe temperature sensor using the second temperature measurement method has better detection accuracy and response speed, but it requires more complex installation and maintenance. For sensors installed inside the pipe, the installation process is more complicated, so professional tools and technicians are required to operate it. In addition, maintenance and calibration require stopping the machine or disassembling the pipe, which also increases the daily maintenance cost. Utility Model Content

[0006] In view of this, the present invention provides a thermally conductive fixing component for a hot and cold carbon meter and a temperature measuring device including the thermally conductive fixing component, so as to eliminate or improve one or more defects existing in the prior art.

[0007] In the first aspect, this utility model provides a thermally conductive fixing component for a hot and cold carbon meter, used to fix a water pipe temperature sensor to the outer surface of a water pipe.

[0013] In some embodiments, the outer heat insulation layer includes a heat insulation pad, the area of ​​which is larger than the area of ​​the inner heat-conducting layer. The outer edge of the inner side of the heat insulation pad is provided with a circumferential raised barrier. The height of the raised barrier is configured to enclose the inner heat-conducting layer and the middle heat-conducting layer, so that after the heat-conducting fixing assembly installs the water pipe temperature sensor on the outer surface of the water pipe, its circumferential outer edge forms a closed structure.

[0014] In some embodiments, the thickness of the thermally conductive inner layer and / or the thermally insulating outer layer is greater at the location corresponding to the sensor mounting structure than at other locations.

[0015] In some embodiments, the thermally conductive fixing assembly further includes a fixing member, which includes any one of a fixing strap, a pipe clamp, and an adhesive tape.

[0016] In some embodiments, the length L of the heat-conducting inner layer is configured as: 1 / 4πR≤L≤πR, where R is the outer diameter of the water pipe.

[0017] In some embodiments, the temperature resistance range of the copper foil graphite sheet is -200℃ to +400℃, the thermal conductivity in the vertical direction is 300W / (mK), and the thermal conductivity in the horizontal direction is 1500W / (mK).

[0018] In some embodiments, the area of ​​the copper foil graphite sheet is less than or equal to the area of ​​the thermally conductive inner layer, the area of ​​the fixed copper sheet is less than or equal to the area of ​​the thermally conductive inner layer, and the area of ​​the copper foil graphite sheet is greater than, less than, or equal to the area of ​​the fixed copper sheet.

[0019] In some embodiments, the groove is configured such that, after the thermally conductive fixing assembly mounts the water pipe temperature sensor on the outer surface of the water pipe, the groove extends along the generatrix direction of the water pipe.

[0020] Secondly, this utility model also provides a temperature measuring device for a hot and cold carbon meter.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0033] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0034] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0035] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0036] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0037] To address the problems of inconvenient installation and inaccurate temperature detection when water pipe temperature sensors (hereinafter referred to as sensors) are mounted on the surface of water pipes, this invention provides a thermally conductive fixing component for a hot and cold carbon meter and a temperature measuring device based on the thermally conductive fixing component. Unlike existing technologies that directly expose and fix the water pipe temperature sensor to the surface of the water pipe, this invention uses a thermally conductive fixing component, which improves the stability and ease of installation. The installation process eliminates the need for multiple adjustments to the installation position, simplifying the installation steps. Simultaneously, the thermally conductive fixing component provides insulation and protection for the outside of the water pipe temperature sensor, reducing temperature interference from the external environment and protecting the sensor from damage caused by external impacts and vibrations. Furthermore, in practical use, the water pipe temperature sensor should avoid direct exposure to sunlight or other external heat sources to prevent errors. The sensor's installation location should also ensure easy maintenance and upkeep, facilitating daily inspection and calibration.

[0038] In a first aspect, embodiments of this utility model provide a heat-conducting fixing component 1 for a hot and cold carbon meter, such as... Figure 1 As shown, the thermally conductive fixing component 1 is used to fix the water pipe temperature sensor 3 to the outer surface of the water pipe 4. The thermally conductive fixing component 1 includes a thermally conductive inner layer 11, a thermally conductive middle layer 12, and a thermally insulating outer layer 13 arranged layer by layer from the inside to the outside. The layered structure of the thermally conductive fixing component 1 is conducive to realizing different thermal conduction and thermal insulation functions, so as to improve the temperature measurement effect of the sensor.

[0039] The thermally conductive inner layer 11 is fixed to the outer surface of the water pipe 4 by its own adhesive inner surface 112 or by a coated adhesive. The adhesive material used for the adhesive inner surface 112 or the coated adhesive must be thermally conductive. For example, using thermally conductive materials such as thermally conductive epoxy resin and thermally conductive gel can reduce energy loss between the pipe wall and the thermally conductive inner layer 11. Setting the adhesive inner surface 112 or adhesive between the thermally conductive inner layer 11 and the pipe wall is beneficial to improving the energy conduction efficiency between the two. Compared with the direct contact between the thermally conductive inner layer 11 and the pipe wall, setting an adhesive fluid structure between the two can better fill the gaps and cavities in the contact area, thereby improving the energy transfer efficiency and improving the detection accuracy of the temperature sensor.

[0040] The thermally conductive intermediate layer 12 has a sensor mounting structure 123 for mounting the water pipe temperature sensor 3 on the thermally conductive inner layer 11. The water pipe temperature sensor 3 is detachably mounted inside the sensor mounting structure 123 by means of pressing, clamping or threading, which is beneficial for calibrating and maintaining the water pipe temperature sensor 3 separately during daily use.

[0041] The area of ​​the heat-insulating outer layer 13 is configured to at least cover the sensor mounting structure 123. The heat-insulating outer layer 13 can reduce the energy exchange between the sensor and the external environment, prevent changes in ambient temperature from affecting the detection data of the water pipe temperature sensor, and improve the stability and accuracy of temperature detection.

[0042] For the thermally conductive inner layer 11 of the aforementioned thermally conductive fixing component 1, compared with the existing clamp fixing or ring fixing, the fixing method of the thermally conductive inner layer 11 in the above embodiment is to set an adhesive inner surface 112 or to coat the contact surface with adhesive, which can obtain a larger contact area, making the installation on the water pipe surface more firm and reliable. At the same time, the thermally conductive inner layer 11 adheres more tightly to the pipe wall, achieving seamless adhesion to the water pipe surface, which is beneficial to improving the thermal conductivity of the thermally conductive inner layer 11, thereby enabling the sensor to accurately sense the fluid temperature inside the water pipe.

[0043] In the above embodiments, the thermally conductive fixing component 1 of this utility model can simplify the installation steps of the water pipe temperature sensor 3, thereby reducing the difficulty of its installation and maintenance, which is conducive to the water pipe temperature sensor 3 adapting to more working environments and reducing operating costs. The thermally conductive fixing component 1 of this utility model can also ensure that the water pipe temperature sensor 3 has good detection accuracy and response speed, while reducing the impact of environmental changes on the temperature measurement results.

[0044] In some embodiments, such as Figure 2As shown, the thermally conductive intermediate layer 12 includes a first metal layer 121 and a second metal layer 122. A groove is formed between the first metal layer 121 and the second metal layer 122, or a groove is formed between the first metal layer 121 and the thermally conductive inner layer 11, serving as the sensor mounting structure 123, allowing the water pipe temperature sensor 3 to directly contact the outer or inner surface of the first metal layer 121 for heat conduction. For example, if the groove is located on the second metal layer 122, the direction of the groove opening can be set towards the center of the water pipe 4; if the groove is located on the thermally conductive inner layer 11, the direction of the groove opening can be set away from the center of the water pipe 4. Including but not limited to this, the groove mainly serves as the mounting space for the water pipe temperature sensor 3, ensuring that the water pipe temperature sensor 3 can be stably installed and that the first metal layer 121 and the water pipe temperature sensor 3 can be in close contact. In addition, the metal material has a stable shape structure and good thermal conductivity, which is used to ensure the stability of the central groove structure. At the same time, the metal of the thermally conductive intermediate layer 12 can conduct the heat of the thermally conductive inner layer to the water pipe temperature sensor 3. The first and second metal layers can be made of materials such as aluminum, silver, copper, and gold, but are not limited to these.

[0045] In some embodiments, such as Figure 3 As shown, the first metal layer 121 includes a copper foil graphite sheet 121-1, which comprises a copper foil and a graphene coating applied to at least one surface of the copper foil. For example, the copper foil is a thin sheet structure of copper with a thickness of 5-105 μm, which has good thermal conductivity and ductility, and is used as a coating carrier for the graphene coating and for conducting heat. Graphene is a two-dimensional material with a single atom thickness and excellent thermal conductivity. Its thermal conductivity is higher than that of bulk graphite and diamond, and it has the highest thermal conductivity among known materials. Therefore, coating the surface of the copper foil with a graphene coating can effectively improve the thermal conductivity.

[0046] The aforementioned copper foil graphite sheet 121-1 is a novel thermally conductive material. Its flexible material allows it to fit tightly against the water pipe temperature sensor 3, rapidly transferring absorbed heat to the sensor. The copper foil graphite sheet 121-1 has a temperature range of -200℃ to +400℃, a vertical thermal conductivity of 300W / (mK), and a horizontal thermal conductivity of 1500W / (mK). The copper foil graphite sheet 121-1 enhances the thermal conductivity of the copper foil. The surface is coated with a high-efficiency thermal radiation nano-carbon graphene material coating. During operation, heat from the heat source is rapidly conducted to the copper foil layer through the thermally conductive particles in the thermally conductive double-sided adhesive. The high longitudinal thermal conductivity of the copper foil allows heat to be rapidly conducted longitudinally. After the heat is conducted to the graphene coating, the high lateral thermal conductivity of the graphene rapidly conducts the heat laterally to the area around the sensor. The high lateral thermal conductivity of the graphene is achieved by converting thermal energy into infrared radio frequency through the high thermal radiation efficiency of the carbon atoms in the nano-carbon coating, radiating heat into the surrounding space. In special cases where the temperature distribution is uneven due to the high or low temperature in a specific area of ​​the pipe wall, the copper foil graphite sheet 121-1 of the thermally conductive intermediate layer 12 can conduct heat evenly to the entire planar structure of the thermally conductive intermediate layer 12, so that the temperature of the thermally conductive intermediate layer 12 in different areas remains within a stable range, which is beneficial to the accuracy of the temperature measurement data of the temperature sensor.

[0047] In some embodiments, the second metal layer 122 includes a fixing copper plate 122-1 for pressing the sensor mounting structure 123 onto the copper foil graphite sheet 121-1. The groove is located on the fixing copper plate 122-1 or the thermally conductive inner layer 11. For example, the thickness of the fixing copper plate 122-1 can be set to 1-5 mm. Since the fixing copper plate 122-1 is thicker than the copper foil graphite sheet 121-1, the structural stability of the fixing copper plate 122-1 is better than that of the copper foil graphite sheet 121-1. Therefore, the groove can be set on the fixing copper plate 122-1. The shape of the groove of the fixing copper plate 122-1 can be the same as the contour of the sensor shape portion, so that the sensor can be tightly pressed onto the copper foil graphite sheet 121-1 by the fixing copper plate 122-1. Figure 3 The groove shown is cylindrical, but not limited to this, such as a polygon.

[0048] Compared to the thickness of the copper foil structure, the fixed copper pressure plate 122-1 has better stability and a certain degree of deformation elasticity. Therefore, setting the groove for installing the sensor on the fixed copper pressure plate 122-1 can not only ensure the stability of the groove structure, but also make the sensor be stably pressed into the inside of the groove under pressure.

[0049] In some embodiments, the thermally conductive inner layer 11 includes thermally conductive silicone 111, which has an adhesive inner surface 112. The thermally conductive silicone 111 has good thermal conductivity, as well as good anti-aging and anti-thermal-temperature alternation properties. It also possesses moisture-proof, shock-proof, and waterproof characteristics, which helps increase the stability and durability of the thermally conductive inner layer 11 during use. The adhesive inner surface 112 of the thermally conductive silicone 111 has good adsorption properties, enabling the thermally conductive inner layer 11 to have both good adhesion and thermal conductivity, facilitating the rapid installation and heat conduction of the thermally conductive fixing component 1.

[0050] In some embodiments, such as Figure 3 As shown, the heat insulation outer layer 13 includes a heat insulation pad 131, which can isolate the energy exchange between the sensor and the external environment, thereby reducing the impact of temperature changes in the environment on the sensor's temperature measurement data.

[0051] Furthermore, the area of ​​the heat-insulating pad 131 is larger than the area of ​​the heat-conducting inner layer 11, which can ensure that the heat collected by the heat-conducting inner layer 11 will not be lost or will be lost to the external environment in a small amount. The heat-insulating pad 131 can also prevent the water pipe temperature sensor 3 from experiencing temperature drift under extreme temperature conditions, which would lead to inaccurate measurement results.

[0052] In some embodiments, such as Figure 4 As shown, the outer edge of the inner side of the heat-insulating pad 131 is provided with a circumferential raised barrier 131-1. The height of the raised barrier 131-1 is configured to enclose the inner heat-conducting layer 11 and the middle heat-conducting layer 12, so that after the water pipe temperature sensor 3 is installed on the outer surface of the water pipe 4, the outer edge of the heat-conducting fixing assembly 1 is a closed structure. The raised barrier 131-1 can prevent heat loss from the inner heat-conducting layer 11 and the middle heat-conducting layer 12 from the edge, and at the same time block foreign objects such as water vapor, air and dust in the external environment from entering the interior of the heat-conducting fixing assembly 1, thereby damaging the internal components. The raised barrier 131-1 helps the heat-insulating pad 131 form a stable isolation space, which can improve the internal heat conduction effect and enhance the protection of the heat-conducting fixing assembly 1. In addition, when the installed water pipe temperature sensor 3 protrudes from the side of the raised enclosure 131-1, an opening with the same shape as the water pipe temperature sensor 3 can be set at the corresponding position to ensure the overall heat insulation effect of the heat insulation pad 131.

[0053] In some embodiments, such as Figure 3As shown, the thickness of the thermally conductive inner layer 11 and / or the thermally insulating outer layer 13 is greater at the location corresponding to the sensor mounting structure 123 than at other locations. When the thermally conductive fixing assembly 1 is installed on the outer surface of the water pipe 4, the thickened structure of the thermally conductive inner layer 11 causes the thermally conductive fixing assembly 1 to form a protrusion on the surface of the water pipe 4, so that the installed water pipe temperature sensor 3 is subjected to greater pressure from the outer fixing member 2 and fits more tightly with the thermally conductive inner layer 11; the thickened structure of the thermally insulating outer layer 13 is used to improve the stability and thermal insulation of the overall structure installation, as well as reduce the damage to the water pipe temperature sensor 3 caused by external impacts and vibrations.

[0054] In some embodiments, such as Figure 1 As shown, the thermally conductive fixing assembly 1 also includes a fixing component 2, which includes any one of a fixing strap, a pipe clamp, and adhesive tape. The appropriate fixing component 2 can be selected according to the different usage scenarios. For example, for usage scenarios requiring long-term temperature measurement in extreme environments, a pipe clamp can be used for fixing; for scenarios with less frequent use (such as maintenance, sampling, etc.), a fixing strap or adhesive tape can be used. The selection and use of the fixing component 2 should ensure stable installation and ease of installation and maintenance for the user.

[0055] In some embodiments, such as Figure 1 As shown, the groove is configured such that after the water pipe temperature sensor 3 is installed on the outer surface of the water pipe 4 by the heat-conducting fixing assembly 1, the extension direction of the groove is along the generatrix of the water pipe 4. This arrangement can obtain a larger contact area with the pipe wall. Compared with the groove being set along the diameter of the water pipe 4 and perpendicular to the generatrix of the water pipe 4, the former arrangement can obtain a larger contact area, resulting in better heat conduction between the water pipe temperature sensor 3 and the water pipe 4. In addition, in the former arrangement, the water pipe 4 and the sensor are in line contact, while in the latter two arrangements, the water pipe 4 and the sensor are in point contact. Line contact not only has a larger contact area than point contact, but also has better overall structural stability.

[0056] In some embodiments, the area of ​​the copper foil graphite sheet 121-1 is less than or equal to the area of ​​the thermally conductive inner layer 11, the area of ​​the fixed copper pressure plate 122-1 is less than or equal to the area of ​​the thermally conductive inner layer 11, and the area of ​​the copper foil graphite sheet 121-1 is greater than, less than, or equal to the area of ​​the fixed copper pressure plate 122-1. The size of the copper foil graphite sheet 121-1 is related to the size of the thermally conductive inner layer 11, and the size of the fixed copper pressure plate 122-1 is related to the size of the sensor. Under the above conditions, setting a larger area for the thermally conductive inner layer 11 and the copper foil graphite sheet 121-1 can improve the accuracy and stability of the temperature sensor.

[0057] In some embodiments, the length L of the thermally conductive inner layer 11 is configured as follows: 1 / 4πR ≤ L ≤ πR, where R is the outer diameter of the water pipe. The shortest length of the thermally conductive inner layer 11 can be set to 1 / 4 of the circumference of the water pipe to ensure the accuracy of temperature measurement and the secure installation of the sensor. The longest length of the thermally conductive inner layer 11 can be set to the circumference of the water pipe to ensure the portability of the thermally conductive fixing assembly during actual installation. It is understood that the length of the thermally conductive inner layer 11 (i.e., the dimension along the axial direction of the water pipe after installation) is less than a full circle for easy installation; within a circle, the longer its length (with the same width), the more heat is covered and collected from the pipe wall, and the better the heat conduction or heat transfer effect. In addition, considering material costs and installation convenience, the length L of the thermally conductive inner layer 11 can be designed between 1 / 4πR ≤ L ≤ 1 / 2πR, but it is not limited to this, and a length less than 1 / 4πR is also applicable.

[0058] Furthermore, the dimension of the heat insulation pad 131 along the axial direction of the water pipe is configured to be greater than or equal to the length of the water pipe temperature sensor 3 along the axial direction of the water pipe. This ensures that when the water pipe temperature sensor 3 is mounted on the thermally conductive fixing assembly 1, the main structure of the sensor can be enclosed inside the raised enclosure 131-1. In this case, the raised enclosure 131-1 has the best insulation effect due to the absence of raised openings around its perimeter, resulting in better stability and accuracy of the data detected by the water pipe temperature sensor 3. In some embodiments, if the length of the water pipe temperature sensor 3 is greater than the dimension of the heat insulation pad 131 along the axial direction of the water pipe, an opening structure can be designed at the corresponding location of the raised enclosure 131-1 of the heat insulation pad 131.

[0059] In some embodiments, to further improve installation efficiency and simplify installation steps, the multi-layer structure of the thermally conductive fixing assembly 1 can be configured as an interconnected integral structure. For example, the thermally conductive inner layer 11, the thermally conductive intermediate layer 12, and the thermally insulating outer layer 13 can be bonded together sequentially using a thermally conductive adhesive, which simplifies installation steps and improves work efficiency. Alternatively, an installation groove can be provided on the inner side of the thermally insulating outer layer 13, and the thermally conductive intermediate layer 12 and the thermally conductive inner layer 11 can be sequentially placed into the installation groove for installation and fixation. Including but not limited to these, during use, it is only necessary to ensure that the thermally conductive inner layer 11, the thermally conductive intermediate layer 12, and the thermally insulating layer 13 are fixed to the surface of the water pipe 4 layer by layer from the inside out.

[0060] Secondly, this utility model also provides a temperature measuring device, which includes the above-mentioned heat-conducting fixing component 1 and a water pipe temperature sensor 3. The water pipe temperature sensor 3 is installed at the sensor mounting structure 123 position of the heat-conducting intermediate layer 12.

[0061] In practical applications, the aforementioned temperature measuring device may also include a corresponding temperature control system. This system can adjust and control the pipe temperature accordingly. The water pipe temperature sensor 3 can directly transmit the detected data to the temperature control system via a signal connection line or a wireless transmission module, enabling remote real-time monitoring of the pipe temperature. Furthermore, the type of water pipe temperature sensor 3 can be selected based on the actual application scenario, including patch-type and cylindrical sensors.

[0062] According to the technical solutions described in the embodiments of the present invention regarding the thermally conductive fixing component of the hot and cold carbon meter and the temperature measuring device including the thermally conductive fixing component, the beneficial effects that can be achieved include at least the following:

[0063] (1) The overall structure of the heat-conducting fixing component 1 is a flexible structure, which can be rolled and attached to the outer surface of the water pipe 4 during installation, making it convenient for daily installation and maintenance of the heat-conducting fixing component 1, and helping to adapt to more working environments and reduce operating costs.

[0064] (2) The thermally conductive fixing component 1 adopts a layered design, which enables the thermally conductive inner layer 11, the thermally conductive middle layer 12 and the thermally insulating outer layer 13 of the thermally conductive fixing component 1 to achieve different bonding, thermal conduction and thermal insulation functions.

[0065] (3) The thermally conductive inner layer 11 includes a thermally conductive silicone 111 with an adhesive inner surface 112, which can improve the thermal conductivity and adhesion of the thermally conductive fixing component 1, and is conducive to improving the thermal conductivity and ease of installation of the thermally conductive fixing component.

[0066] (4) The thermally conductive intermediate layer, including copper foil and graphite sheet 121-1, can improve the thermal conductivity of the thermally conductive intermediate layer 12.

[0067] (5) The heat insulation outer layer 13 includes a heat insulation pad 131, which can reduce the influence of the external environment on the sensor, avoid measurement errors and impact damage, and improve the stability of temperature detection data.
