Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a temperature sensing bulb assembly, a heat exchanger, and an air conditioner. Background Technology

[0002] As an indispensable electrical appliance in modern homes and offices, the stability and accuracy of the indoor unit's performance are crucial for providing a comfortable indoor environment. Among its components, the temperature sensor, or temperature sensing element, is a vital part of the indoor unit, responsible for detecting both the ambient indoor temperature and the temperature of the indoor unit's coils. This temperature data is received by the controller, which adjusts the air conditioner's operating status to achieve the preset indoor temperature.

[0003] Traditional temperature sensor designs typically consist of a terminal, two thermistors, and necessary connecting materials. The copper tube temperature sensor, due to its excellent thermal conductivity and corrosion resistance, is often used to detect the indoor unit's coil temperature. The other thermistor monitors the ambient indoor temperature, and the terminal acts as a connecting bridge, tightly linking the temperature sensor to the controller to ensure accurate temperature data transmission.

[0004] During the installation of temperature sensors, especially those used to detect the temperature of the indoor unit's coils, the placement method is crucial. Generally, the sensor's sleeve is welded to the bend of the coil to obtain the most accurate temperature information. In this process, metal inserts, as additional components, play a vital role in securing the copper tube temperature sensor. Since the inner diameter of the sleeve is usually larger than the outer diameter of the copper tube temperature sensor, without the constraint of the metal inserts, the copper tube temperature sensor may shift or detach within the sleeve, thus affecting the accuracy of temperature detection.

[0005] For example, in the existing published patent CN110726205, a cleverly designed metal insert structure achieves effective mounting of the copper tube temperature sensor. However, in actual production, this metal insert installation method has revealed some problems. First, the placement process of the metal insert is relatively cumbersome, requiring manual operation by production personnel, which not only increases production costs but also reduces production efficiency. Second, the fixing effect of the metal insert on the copper tube temperature sensor is not ideal, mainly relying on the elasticity of the metal insert itself. This fixing method is prone to loosening or falling off during long-term use or frequent insertion and removal of the copper tube temperature sensor, thus increasing the risk of the copper tube temperature sensor becoming displaced or falling off. In addition, the metal insert is also prone to falling off during insertion and removal, which can damage not only the metal insert itself but also other components of the air conditioner indoor unit.

[0006] In summary, the existing temperature sensing bag installation methods have certain shortcomings in terms of production efficiency and cost, and there is an urgent need for a simpler, more efficient and reliable temperature sensing bag structure solution to solve the above problems.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] In a first aspect, this utility model provides a temperature sensing bag assembly, including: a sleeve and a temperature sensing bag, wherein the inner wall of the sleeve is provided with at least two positioning protrusions, and the temperature sensing bag is inserted into the sleeve and abuts against the positioning protrusions, so that the temperature sensing bag and the sleeve form an interference fit.

[0014] In one specific embodiment, the distance between the center point of the positioning protrusion and the bottom of the sleeve is 6mm-10mm.

[0015] In one specific embodiment, all the positioning protrusions are located on the same horizontal line.

[0016] In one specific embodiment, the number of positioning protrusions is three, and they are evenly distributed on the inner wall of the sleeve.

[0017] The advantages of this temperature-sensing bulb assembly compared to existing technologies are as follows: By providing at least two positioning protrusions on the inner wall of the sleeve, the temperature-sensing bulb can tightly abut against these positioning protrusions after being inserted into the sleeve, forming an effective interference fit. This design not only ensures a firm and reliable connection between the temperature-sensing bulb and the sleeve, but also avoids loosening problems caused by vibration or temperature changes, thereby improving the stability and durability of the entire temperature-sensing bulb assembly. In addition, by directly inserting the temperature-sensing bulb into the sleeve and using the positioning protrusions to achieve a stable connection, additional material costs are eliminated, which not only simplifies the production process and improves production efficiency, but also significantly reduces the overall manufacturing cost and enhances the market competitiveness of the product.

[0018] Secondly, this utility model embodiment provides a heat exchanger, including the temperature sensing bulb assembly as described above.

[0019] Compared with the prior art, the heat exchanger of this utility model has the following advantages: by applying the temperature sensing bulb assembly mentioned above, not only is the connection between the temperature sensing bulb and the sleeve secure and reliable, but loosening caused by vibration or temperature changes is also avoided, thereby improving the stability and durability of the entire heat exchanger; in addition, by directly inserting the temperature sensing bulb into the sleeve and using the positioning protrusions to achieve a stable connection, additional material costs are eliminated, which not only simplifies the production process and improves production efficiency, but also significantly reduces the manufacturing cost of the heat exchanger and enhances the market competitiveness of the product.

[0020] Thirdly, this utility model embodiment provides an air conditioner, including the heat exchanger described above.

[0021] Compared with the prior art, the beneficial effects of this air conditioner are as follows: by applying the heat exchanger mentioned above, not only is the connection between the temperature sensing bulb and the sleeve secure and reliable, but also the loosening problem caused by vibration or temperature changes is avoided, thereby improving the stability and durability of the entire air conditioner; in addition, by directly inserting the temperature sensing bulb into the sleeve and using the positioning protrusions to achieve a stable connection, additional material costs are saved, which not only simplifies the production process and improves production efficiency, but also significantly reduces the manufacturing cost of the air conditioner and enhances the market competitiveness of the product.

[0037] See Figures 1 to 4 As shown, this utility model discloses a specific embodiment of a temperature sensing bag assembly, including: a sleeve 10 and a temperature sensing bag 20. The inner wall of the sleeve 10 is provided with at least two positioning protrusions 11. The temperature sensing bag 20 is inserted into the sleeve 10 and abuts against the positioning protrusions 11, so that the temperature sensing bag 20 and the sleeve 10 form an interference fit.

[0038] Specifically, by providing at least two positioning protrusions 11 on the inner wall of the sleeve 10, the outer side of the temperature sensing bulb 20 can tightly abut against these positioning protrusions 11 after being inserted into the sleeve 10, forming an effective interference fit. This design not only ensures a firm and reliable connection between the temperature sensing bulb 20 and the sleeve 10, but also avoids loosening caused by vibration or temperature changes, thereby improving the stability and durability of the entire temperature sensing bulb assembly. Furthermore, by directly inserting the temperature sensing bulb 20 into the sleeve 10 and using the positioning protrusions 11 to achieve a stable connection, additional material costs are eliminated, simplifying the production process, improving production efficiency, significantly reducing overall manufacturing costs, and enhancing the product's market competitiveness. In addition, the direct insertion installation method greatly simplifies the assembly process between the temperature sensing bulb 20 and the sleeve 10. Compared to traditional installation methods, there is no need for complex fixing steps or long waiting times (such as adhesive curing), thus significantly shortening assembly time and improving production efficiency. Moreover, this "plug-and-play" design facilitates subsequent maintenance and replacement, reducing maintenance costs and time. In addition, the design of the copper tube temperature sensor of the temperature sensor 20 being directly inserted into the sleeve 10 not only simplifies the structure but also ensures that the temperature sensor can respond quickly and accurately to temperature changes, improving the sensitivity and accuracy of the temperature sensor assembly. This is especially important for systems that require precise temperature control and helps to improve the performance and stability of the entire system.

[0039] See Figures 3 to 4 As shown, in one embodiment, the positioning protrusion 11 is hemispherical.

[0040] Specifically, the positioning protrusions 11 are designed in a hemispherical shape, meaning that each positioning protrusion 11 has a smooth, hemispherical surface. This design not only ensures a moderate contact area between the positioning protrusions 11 and the temperature sensing bulb 20, but also provides sufficient mechanical support to prevent the temperature sensing bulb 20 from shifting within the sleeve 10. Furthermore, the positioning protrusions 11 are evenly distributed on the inner wall of the sleeve 10, with their number and position carefully calculated based on the size of the sleeve 10 and the dimensions of the temperature sensing bulb 20. Typically, at least two positioning protrusions 11 are provided to ensure the stability and symmetry of the temperature sensing bulb 20 within the sleeve 10. In more complex designs, more positioning protrusions 11 may be used to provide additional support and stability. Additionally, during installation, the copper tube temperature sensing head of the temperature sensing bulb 20 is directly inserted into the sleeve 10 until the outer side of the copper tube temperature sensing head is in close contact with the positioning protrusions 11. Due to the hemispherical shape and appropriate size design of the positioning protrusion 11, the temperature sensing bulb 20 can easily slide into the sleeve 10 and be obstructed by the positioning protrusion 11 when it reaches the correct position, thereby achieving a stable connection.

[0041] More specifically, the hemispherical positioning protrusions 11 provide a smooth and uniform contact surface, reducing stress concentration caused by irregular shapes. This helps ensure a stable connection of the temperature sensor 20 within the sleeve 10, maintaining its firmness even under extreme conditions such as vibration or temperature changes. Furthermore, the hemispherical positioning protrusions 11 make it easier for the temperature sensor 20 to slide into the sleeve 10, reducing friction and resistance during assembly. This simplifies assembly steps and reduces the risk of damage to the temperature sensor 20 or the sleeve 10 during assembly. Additionally, the additional mechanical support provided by the positioning protrusions 11 makes the connection between the temperature sensor 20 and the sleeve 10 more secure, helping to reduce loosening or damage caused by long-term vibration or temperature changes, thereby extending the service life of the entire temperature sensor assembly. Moreover, the hemispherical positioning protrusions 11 ensure the correct position of the temperature sensor 20 within the sleeve 10, improving the accuracy of temperature detection. This precise positioning helps ensure that the temperature sensor 20 accurately senses and responds to changes in indoor temperature, providing reliable feedback to the air conditioning system.

[0042] In one embodiment, the height of the positioning protrusion 11 is 0.5mm-2mm.

[0043] Specifically, the height of the positioning protrusions 11 is controlled through a precision manufacturing process to ensure that the height of each protrusion is within the range of 0.5mm to 2mm. Depending on the specific application requirements, the height of the positioning protrusions 11 can be adjusted within this range. For example, in applications requiring higher stability, a higher positioning protrusion 11 can be selected; while in applications requiring higher assembly precision, a lower positioning protrusion 11 can be selected.

[0044] More specifically, the appropriate height of the positioning protrusion 11 allows the temperature sensor 20 to be precisely inserted into the sleeve 10 and in close contact with the positioning protrusion 11. This precise assembly helps ensure the correct position of the temperature sensor 20 within the sleeve 10, thereby improving the accuracy of temperature detection. Furthermore, the height of the positioning protrusion 11 provides sufficient mechanical support to prevent the temperature sensor 20 from shifting or falling out within the sleeve 10. This stability is crucial for ensuring the reliability of the temperature sensor assembly during long-term use. Additionally, by controlling the height of the positioning protrusion 11, the stress distribution between the temperature sensor 20 and the sleeve 10 can be optimized. An appropriate height helps reduce the risk of damage due to stress concentration, thereby extending the service life of the temperature sensor assembly. Moreover, the height range of 0.5mm to 2mm allows the temperature sensor assembly to adapt to different working environments and conditions. Whether in industrial environments with high vibration or in outdoor environments with drastic temperature changes, the temperature sensor assembly maintains stable performance.

[0045] In one embodiment, the diameter of the positioning protrusion 11 is 1.5mm-2.5mm.

[0046] Specifically, positioning protrusions 11 are evenly distributed on the inner wall of the sleeve 10, and the appropriate number and position of the positioning protrusions 11 are determined according to the size of the sleeve 10 and the size of the temperature sensing bulb 20. The diameter and layout of the positioning protrusions 11 together ensure the stability and symmetry of the temperature sensing bulb 20 within the sleeve 10. To enhance the durability and wear resistance of the positioning protrusions 11, high-strength, wear-resistant materials are typically selected to manufacture the sleeve 10, such as stainless steel, copper alloy, or special alloys. Furthermore, necessary surface treatments, such as polishing or spraying a wear-resistant layer, on the inner wall of the sleeve 10 can further improve the durability and connection stability of the protrusions.

[0047] More specifically, the appropriate diameter of the positioning protrusion 11 allows the temperature sensor 20 to fit tightly against the inner wall of the sleeve 10 and form good contact with the positioning protrusion 11. This tight fit and contact helps prevent the temperature sensor 20 from shifting or falling off within the sleeve 10, thereby improving connection stability. Furthermore, the moderate diameter of the positioning protrusion 11 makes it easier for the temperature sensor 20 to be inserted into the sleeve 10 and achieves a quick and accurate connection with the positioning protrusion 11. This optimized assembly process not only improves assembly efficiency but also reduces the risk of damaging the temperature sensor 20 or the sleeve 10 during assembly. Additionally, a larger diameter of the positioning protrusion 11 provides a larger contact area and stronger mechanical support, thereby enhancing the durability and wear resistance between the temperature sensor 20 and the sleeve 10. This helps extend the service life of the temperature sensor assembly and reduces loosening or damage caused by long-term vibration or temperature changes. In addition, a stable connection and a suitable diameter of the positioning protrusion 11 help ensure that the temperature sensor 20 can accurately sense and respond to changes in indoor temperature. This accuracy is crucial for the performance and control precision of the air conditioning system and helps to provide a more comfortable and stable indoor environment.

[0048] In one embodiment, the distance between the center point of the positioning protrusion 11 and the bottom of the sleeve 10 is less than one-third of the length of the sleeve 10.

[0049] Specifically, firstly, based on the overall design and application requirements of the temperature sensing bulb assembly, the length of the sleeve 10 is determined. This length needs to be sufficient to accommodate the copper tube temperature sensing head of the temperature sensing bulb 20, while also considering the position and number of positioning protrusions 11. Next, using one-third of the sleeve 10 length as a reference, the maximum height at which the center point of the positioning protrusion 11 can be placed is calculated. To ensure that the temperature sensing bulb 20 can be inserted to a sufficient depth during assembly, the center point of the positioning protrusion 11 is set below this calculated height. During assembly, the insertion depth of the temperature sensing bulb 20 is monitored to ensure it can make tight contact with the positioning protrusion 11, thereby ensuring the accuracy and consistency of the assembly process.

[0050] More specifically, by setting the center point of the positioning protrusion 11 to less than one-third of the length of the sleeve 10, it is ensured that the temperature sensor 20 can be inserted to a sufficient depth during assembly. This helps to achieve a stable connection between the temperature sensor 20 and the sleeve 10 and prevents loosening or failure of the connection due to insufficient insertion depth. Furthermore, precise positioning of the positioning protrusion 11 and control of the manufacturing process ensure that the temperature sensor 20 accurately contacts the positioning protrusion 11 during assembly. This improves the accuracy and consistency of assembly and helps to ensure that each temperature sensor assembly has the same performance and quality. Additionally, placing the positioning protrusion 11 to less than one-third of the length of the sleeve 10 helps to optimize the structural compactness of the temperature sensor assembly, making it smaller, lighter, and easier to adapt to different installation spaces and requirements. Moreover, because the temperature sensor 20 can be inserted to a sufficient depth and make close contact with the positioning protrusion 11, the connection is more stable and reliable. This helps to reduce loosening or failure of the connection due to vibration or temperature changes, thereby extending the service life of the temperature sensor assembly.

[0051] In one embodiment, the distance between the center point of the positioning protrusion 11 and the bottom of the sleeve 10 is 6mm-10mm.

[0052] Specifically, firstly, the length of the copper tube temperature sensor of the temperature sensing bulb 20 needs to be accurately measured. This is usually done using precision measuring tools (such as vernier calipers or micrometers) to ensure the accuracy of the measurement results. Secondly, based on application requirements and system design, the depth to which the copper tube temperature sensor of the temperature sensing bulb 20 needs to be inserted into the sleeve 10 is determined. This depth requirement is usually clearly stated in the system's technical specifications or design requirements. Furthermore, combining the length of the copper tube temperature sensor and the required insertion depth, a suitable distance between the center point of the positioning protrusion 11 and the bottom of the sleeve 10 is calculated. This distance should ensure that during assembly, the copper tube temperature sensor of the temperature sensing bulb 20 can be fully inserted into the sleeve 10 and form good contact with the positioning protrusion 11, while also meeting the system's technical requirements for insertion depth.

[0053] More specifically, by setting the distance between the center point of the positioning protrusion 11 and the bottom of the sleeve 10 to between 6mm and 10mm, and determining this distance based on the length of the copper tube temperature sensing head of the temperature sensing bulb 20 and related insertion depth technical requirements, it can be ensured that the temperature sensing bulb 20 can be inserted to the correct depth during assembly. This helps to achieve a stable connection between the temperature sensing bulb 20 and the sleeve 10, and prevents loosening or failure of the connection due to improper insertion depth. Furthermore, precise positioning of the positioning protrusion 11 and manufacturing process control ensure that the temperature sensing bulb 20 accurately contacts the positioning protrusion 11 during assembly. This improves assembly accuracy and consistency, helping to ensure that each temperature sensing bulb assembly has the same performance and quality. In addition, the correct insertion depth and stable connection help optimize the performance of the temperature sensing bulb assembly, enabling the temperature sensing bulb 20 to more accurately sense and respond to temperature changes, thereby providing more precise temperature control for the system. In addition, a stable connection and the correct insertion depth help enhance the reliability and durability of the temperature sensor assembly, which reduces the risk of connection loosening or failure due to vibration, temperature changes or long-term use, thereby extending the service life of the temperature sensor assembly.

[0054] See Figures 1 to 4 As shown, in one embodiment, all the positioning protrusions 11 are located on the same horizontal line.

[0055] Specifically, during the manufacturing of the sleeve 10, high-precision processing equipment and processes, such as CNC lathes or laser cutting, are employed to ensure that the shape, size, and position of each positioning protrusion 11 meet the design requirements. Strict manufacturing process control ensures that all positioning protrusions 11 are on the same horizontal line. Furthermore, after manufacturing, each sleeve 10 is inspected and calibrated to ensure that all positioning protrusions 11 are on the same horizontal line. This can be accomplished using specialized inspection tools (such as a level or optical measuring instrument) to ensure that design requirements are met.

[0056] More specifically, by ensuring that all positioning protrusions 11 are on the same horizontal line, the assembly accuracy of the temperature sensor 20 can be greatly improved. This helps reduce assembly errors and ensures a stable and reliable connection between the temperature sensor 20 and the sleeve 10. Furthermore, when the temperature sensor 20 is inserted into the sleeve 10, all positioning protrusions 11 being on the same horizontal line ensures that the temperature sensor 20 is subjected to uniform force. This helps prevent loosening or failure of the connection due to uneven force, thereby improving the reliability and durability of the temperature sensor assembly. Additionally, a stable connection and uniform force distribution help ensure that the temperature sensor 20 can accurately sense and respond to temperature changes, which helps improve the accuracy of temperature detection and provides more precise temperature control for the system. Moreover, ensuring that all positioning protrusions 11 are on the same horizontal line simplifies the assembly process of the temperature sensor 20, which helps reduce assembly time and costs and improve production efficiency.

[0057] In one embodiment, the number of positioning protrusions 11 is three, and they are evenly distributed on the inner wall of the sleeve 10.

[0058] Specifically, based on the design requirements and application needs of the temperature sensing element assembly, the number of positioning protrusions 11 is determined to be three. This number was determined after considering the structural compactness, connection stability, and ease of assembly of the temperature sensing element assembly. Furthermore, on the inner wall of the sleeve 10, precision measuring tools and positioning devices are used to ensure that the three positioning protrusions 11 are evenly distributed. This means that the intervals between adjacent positioning protrusions 11 are equal, and they are all located at appropriate positions on the inner wall of the sleeve 10, ensuring that the temperature sensing element 20 can be stably fixed inside the sleeve 10 during assembly.

[0059] More specifically, the three positioning protrusions 11 are evenly distributed on the inner wall of the sleeve 10, ensuring that the temperature sensor 20 is stably fixed inside the sleeve 10 during assembly. This stable connection helps prevent loosening or failure due to vibration or temperature changes, thereby improving the reliability of the temperature sensor assembly. Furthermore, when the temperature sensor 20 is inserted into the sleeve 10, the three positioning protrusions 11 ensure that the temperature sensor 20 is evenly stressed. This helps prevent loosening or damage due to uneven stress, thereby extending the service life of the temperature sensor assembly. Additionally, by ensuring that the three positioning protrusions 11 are evenly distributed and of consistent quality, the assembly accuracy of the temperature sensor 20 can be greatly improved. This helps reduce assembly errors and ensures an accurate and reliable connection between the temperature sensor 20 and the sleeve 10. Moreover, the stable connection and uniform stress distribution help optimize the performance of the temperature sensor assembly, enabling the temperature sensor 20 to more accurately sense and respond to temperature changes, thus providing more precise temperature control for the system.

[0060] In one embodiment, the positioning protrusion 11 and the sleeve 10 are integrally formed.

[0061] Specifically, because the positioning protrusion 11 and the sleeve 10 are manufactured using a one-piece molding process, there are no connecting parts or seams between them. Therefore, the overall structure is more robust and durable. This structure can more effectively distribute stress when subjected to external forces, thereby improving the overall strength of the structure. Furthermore, the one-piece molding structure reduces assembly steps in the manufacturing process, thus simplifying the manufacturing process. This not only improves production efficiency but also reduces manufacturing costs. In addition, the one-piece molding structure eliminates traces of connecting parts or seams, making the product appearance cleaner and more aesthetically pleasing, which helps to enhance the overall image and market competitiveness of the product.

[0062] This utility model also discloses a heat exchanger, including the temperature sensing bulb assembly as described above.

[0063] Specifically, by applying the temperature sensing bulb assembly mentioned above, not only is the connection between the temperature sensing bulb 20 and the sleeve 10 secure and reliable, but loosening due to vibration or temperature changes is also avoided, thereby improving the stability and durability of the entire heat exchanger. In addition, by directly inserting the temperature sensing bulb 20 into the sleeve 10 and using the positioning protrusions 11 to achieve a stable connection, additional material costs are eliminated, which not only simplifies the production process and improves production efficiency, but also significantly reduces the manufacturing cost of the heat exchanger and enhances the market competitiveness of the product.

[0064] This utility model also discloses an air conditioner, including the heat exchanger described above.

[0065] Specifically, by applying the heat exchanger mentioned above, not only is the connection between the temperature sensing bulb 20 and the sleeve 10 secure and reliable, but loosening due to vibration or temperature changes is also avoided, thereby improving the stability and durability of the entire air conditioner. In addition, by directly inserting the temperature sensing bulb 20 into the sleeve 10 and using the positioning protrusions 11 to achieve a stable connection, additional material costs are eliminated, which not only simplifies the production process and improves production efficiency, but also significantly reduces the manufacturing cost of the air conditioner and enhances the product's market competitiveness.
