Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a temperature sensing package bracket and a working method thereof, a heat exchanger assembly and an air conditioner. Background Art

[0002] To automatically adjust air conditioning operation, existing air conditioners rely on sensors to detect external conditions. An ambient temperature sensor is one such sensor. Its head is typically installed near the air inlet of the air conditioner's heat exchanger. A common solution involves inserting a sensor bracket through the fins, clipping it onto the heat exchanger's copper tube, and then securing the end of the sensor to the bracket.

[0003] However, the copper tube diameters D of heat exchangers vary widely, with diameters such as φ7, φ8, and φ5 being common. The center-to-center distance P between the two copper tubes also varies, with 22mm and 19.05mm being common. These varying combinations of D and P values ​​necessitate the design of numerous similar-looking bulb brackets, differing only in their mounting feet, for various heat exchangers. This high degree of similarity in appearance can lead to the incorrect bulb bracket being used on a production line, resulting in the risk of the tube cracking or falling out due to incompatible mounting clips.

[0004] There is currently a temperature sensing package bracket that can adapt to various pipe diameters by flipping the bracket, but it cannot adapt to heat exchangers with various center distances. Summary of the Invention

[0005] The first purpose of the present invention is to provide a temperature-sensing package bracket, which can be adapted to heat exchangers with different pipe diameters and different center distances at the same time. It not only solves the risk of using the wrong bracket on the production line, but also saves mold development costs and provides great convenience for the development of models with different cooling capacity sections.

[0006] The second object of the present invention is to provide a method for using the above-mentioned temperature sensing package bracket.

[0007] A third object of the present invention is to provide a heat exchanger assembly using the above-mentioned temperature sensing package bracket.

[0008] A fourth object of the present invention is to provide an air conditioner using the above heat exchanger assembly.

[0009] To achieve the above-mentioned first objective, the present invention provides a temperature sensing bulb bracket, comprising: a bracket body, a first clamping portion provided on one side of the bracket body, the first clamping portion having a first pipeline clamping groove; a clamping member, the clamping member and the first clamping portion being located on the same side of the bracket body and movable relative to the first clamping portion along the Z-axis direction, the clamping member being provided with a second pipeline clamping groove, the opening direction of the second pipeline clamping groove being the same as the opening direction of the first pipeline clamping groove, and the size of the second pipeline clamping groove being equal to the size of the first pipeline clamping groove; a first clamping assembly, the first clamping assembly being opposite to the first clamping portion in the X-axis direction, the first clamping assembly including a first clamping member and a second clamping member arranged along the Z-axis direction, at least one of the first clamping member and the second clamping member being slidably engaged with the bracket body along the Z-axis direction, when the first clamping assembly is in a clamping state, the first clamping member and the second clamping member are close to and enclose a third pipeline clamping groove, the size of the third pipeline clamping groove being smaller than the size of the first pipeline clamping groove, and when the first clamping assembly is in a separated state, the first clamping member is separated from the second clamping member.

[0010] It can be seen from the above scheme that the existing temperature sensing package brackets are difficult to quickly distinguish with the naked eye for temperature sensing package brackets of the same structure used in different heat exchangers due to the similar sizes of the pipeline slots and the similar sizes of the center distances of the pipelines. In the actual production process, incorrect use will occur from time to time. Some temperature sensing package brackets cannot be inserted into the heat exchanger; some temperature sensing package brackets are not stable after being inserted into the heat exchanger, and there is a risk of falling off.

[0011] The present invention adapts to various heat exchanger pipe diameters through the cooperation of the clamping component and the first clamping part, and adapts to various heat exchanger pipe center distances through the sliding cooperation of the clamping part and the bracket body, thereby improving the versatility of the temperature sensing package bracket, reducing the quality risks caused by incorrect use, improving product reliability, and reducing mold costs.

[0012] A preferred solution is that the temperature sensing package bracket also includes a second clamping assembly, which is arranged on the clamping member and is opposite to the second clamping portion of the clamping member in the X-axis direction. The second clamping assembly includes a third clamping member and a fourth clamping member arranged along the Z-axis direction. At least one of the third clamping member and the fourth clamping member slides with the bracket body along the Z-axis direction. When the second clamping assembly is in a clamping state, the third clamping member and the fourth clamping member are close to and form a fourth pipeline slot. The size of the fourth pipeline slot is equal to the size of the third pipeline slot. When the second clamping assembly is in a separated state, the third clamping member is separated from the fourth clamping member.

[0013] It can be seen that stable clamping is achieved through the cooperation between the second clamping assembly and the first clamping assembly. A further solution is that the temperature sensing package bracket also includes a third clamping assembly, the third clamping assembly and the first clamping assembly are arranged along the X-axis direction, the third clamping assembly includes a fifth clamping member and a sixth clamping member arranged along the Z-axis direction, at least one of the fifth clamping member and the sixth clamping member slides with the bracket body along the Z-axis direction, when the third clamping assembly is in a clamping state, the fifth clamping member and the sixth clamping member are close to and surround a fifth pipeline slot, the size of the fifth pipeline slot is smaller than the size of the third pipeline slot, and when the third clamping assembly is in a separated state, the fifth clamping member is separated from the sixth clamping member.

[0014] It can be seen that, by providing the third clamping assembly, the temperature sensing package bracket of the present invention can be applied to heat exchangers with at least three different pipe diameters, further improving the versatility of the temperature sensing package bracket.

[0015] A further solution is that the temperature sensing package bracket also includes a fourth clamping assembly, the fourth clamping assembly is set on the clamping member and is arranged along the X-axis direction with the second clamping assembly, the fourth clamping assembly includes a seventh clamping member and an eighth clamping member arranged along the Z-axis direction, at least one of the seventh clamping member and the eighth clamping member slides with the bracket body along the Z-axis direction, when the fourth clamping assembly is in the clamping state, the seventh clamping member and the eighth clamping member are close to and surround a sixth pipeline slot, the size of the sixth pipeline slot is equal to the size of the fifth pipeline slot, and when the fourth clamping assembly is in the separated state, the seventh clamping member is separated from the eighth clamping member.

[0016] It can be seen that the third clamping assembly and the fourth clamping assembly cooperate to achieve the stable clamping of the temperature sensing package bracket on the pipeline.

[0017] A preferred solution is that the number of the first clamping parts is more than two, each first clamping part is arranged along the X-axis direction, each first clamping part is provided with a first pipeline clamping groove, and each first pipeline clamping groove is coaxially arranged.

[0018] It can be seen that the multiple first clamping portions are arranged along the X-axis direction to ensure that the temperature sensing package bracket is subjected to balanced force in the X-direction, thereby achieving a more stable connection with the heat exchanger pipeline.

[0019] A further solution is that, in the X-axis direction, the first clamping assembly is located between two of the first clamping portions.

[0020] A preferred solution is that the clamping part also includes a connecting portion and at least two second clamping portions, each second clamping portion is arranged along the X-axis direction and protrudes outward from the connecting portion along the Y-axis direction, each second clamping portion is provided with a second pipeline clamping groove, and each second pipeline clamping groove is coaxially arranged.

[0021] Thus, the second clamping parts are connected by the connecting part, so that the clamping part forms an integrated structure, which facilitates the movement of the clamping part relative to the bracket body. At the same time, the provision of multiple coaxial second pipeline clamping grooves ensures the stability of the connection between the clamping part and the pipeline.

[0022] A preferred solution is that the temperature sensing package bracket also includes a clamping drive assembly, which includes a coil, an elastic member, a valve core and a valve seat; the valve seat is arranged on the bracket body, the valve core is arranged on the clamping member, the valve core can move along the valve seat in the Z-axis direction, and the two ends of the elastic member are respectively connected to the bracket body and the valve core; when the coil is energized, the valve core drives the clamping member to move along the positive direction of the Z-axis so that the center distance between the second pipeline slot and the first pipeline slot is the first center distance; when the coil is de-energized, the elastic member drives the valve core to move along the negative direction of the Z-axis until the center distance between the second pipeline slot and the first pipeline slot is the second center distance, and the first center distance is smaller than the second center distance.

[0023] It can be seen that the switching of different pipeline center distances can be achieved through the principle of the solenoid valve, which has a simple structure and can achieve stable switching of the clamping part between two positions.

[0024] A further solution is that the temperature-sensing package bracket further includes a clamping drive assembly, which includes a first electromagnet, a second electromagnet, a first attracted member, and a second attracted member; a first clamping slot extending along the Z-axis direction is provided on the bracket body, the first attracted member and the second attracted member are both slidably matched with the first clamping slot, the first attracted member is arranged on the first clamping member, the second attracted member is arranged on the second clamping member, and the first attracted member and the second attracted member both include magnets; the first electromagnet and the second electromagnet are respectively arranged at both ends of the first clamping slot; when the first clamping assembly is in a clamping state, the first When a positive current is applied to the electromagnet and the second electromagnet, the repulsive force between the first electromagnet and the magnet of the first attracted part forces the first clamping part to move toward the second clamping part, and the repulsive force between the second electromagnet and the magnet of the second attracted part forces the second clamping part to move toward the first clamping part; when the first clamping assembly is in a separated state, a reverse current is applied to the first electromagnet and the second electromagnet, and the attractive force between the first electromagnet and the magnet of the first attracted part forces the first clamping part to move away from the second clamping part, and the attractive force between the second electromagnet and the magnet of the second attracted part forces the second clamping part to move away from the first clamping part.

[0025] It can be seen that the buckle positions of different diameters can be switched through the magnetic attraction principle.

[0026] A preferred solution is that guide openings are provided at the slots of the first pipeline slot, the second pipeline slot, the third pipeline slot and the fourth pipeline slot; the width of each guide opening gradually increases from the end close to the corresponding pipeline slot to the end away from the corresponding pipeline slot; the width of each slot is smaller than the diameter of the corresponding pipeline slot.

[0027] As can be seen, during installation, the clamping portion is inserted through the gap between the fins into the heat exchanger. The guide opening guides the clamping portion, causing it to elastically deform, allowing the pipe clamping slot to engage the heat exchanger pipe. The guide opening facilitates installation of the temperature sensor bracket, and the width of the slot is smaller than the diameter of the corresponding pipe clamping slot, preventing the temperature sensor bracket from falling off the heat exchanger.

[0028] In order to achieve the above-mentioned second purpose, the present invention provides a working method of a temperature-sensing package bracket, which is applied to the above-mentioned temperature-sensing package bracket. The working method includes: obtaining the pipe diameter of the heat exchanger and the center distance between adjacent pipes; and controlling the operation of the coil and the corresponding electromagnet according to the obtained pipe diameter value and center distance value.

[0029] This demonstrates that simply entering a simple code solves the existing problem of misusing the wrong temperature sensor bracket. Unlike conventional designs that rely on specific specifications, this invention allows a single temperature sensor bracket to be used on heat exchangers of varying specifications, completely replacing all existing temperature sensor brackets.

[0030] To achieve the above-mentioned third purpose, the present invention provides a heat exchanger assembly, including a heat exchanger, a temperature sensing package and the above-mentioned temperature sensing package bracket, the temperature sensing package is installed on the temperature sensing package bracket, and the temperature sensing package bracket is connected to the pipeline of the heat exchanger through the corresponding pipeline slot.

[0031] To achieve the fourth objective, the present invention provides an air conditioner comprising the heat exchanger assembly described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See also Figures 3 to 8 The bracket body 1 includes a bracket fixing portion 15 and a partition 16 arranged along the Y-axis direction. The bracket fixing portion 15 is used to fix the temperature-sensing package bracket at a specific position of the heat exchanger. Two first clamping portions 11 are provided on the side wall of the partition 16 away from the bracket fixing portion 15. The first clamping portions 11, the partition 16 and the bracket fixing portion 15 are integrally formed. Each first clamping portion 11 is arranged along the X-axis direction. Each first clamping portion 11 is provided with a first pipeline clamping groove 12, and each first pipeline clamping groove 12 is arranged coaxially. Multiple first clamping portions 11 are arranged along the X-axis direction to ensure that the temperature-sensing package bracket is subjected to balanced force in the X-direction, thereby achieving a more stable connection with the heat exchanger pipeline.

[0052] The clip 2 and the first clip 11 are located on the same side of the bracket body 1, and the clip 2 can move along the Z-axis direction relative to the first clip 11. Specifically, a clip groove 14 extending along the Z-axis is provided on the negative side of the Z-axis of the first clip 11 on the bracket body 1, and the clip 2 slides in cooperation with the clip groove 14. In addition, the clip 2 and the clip groove 14 are upper-limited in the Y-axis direction to prevent the clip 2 from falling off the bracket body 1.

[0053] The connector 2 includes a connecting portion 21 and two second connecting portions 22. Each second connecting portion 22 is arranged along the X-axis and protrudes outward from the connecting portion 21 along the Y-axis. Each second connecting portion 22 is provided with a second pipeline retaining slot 23. The second pipeline retaining slots 23 are coaxially arranged, with the opening direction of the second pipeline retaining slots 23 being the same as the opening direction of the first pipeline retaining slot 12. The dimensions of the second pipeline retaining slots 23 are equal to those of the first pipeline retaining slot 12. The connecting portion 21 connects the second connecting portions 22, forming a single-piece structure for the connector 2, facilitating its movement relative to the bracket body 1. The provision of multiple coaxial second pipeline retaining slots 23 also ensures a stable connection between the connector 2 and the pipeline.

[0054] In the X-axis direction, the first clamping assembly 3 and the third clamping assembly 5 are both located between the two first clamping portions 11 , and the second clamping assembly 4 and the fourth clamping assembly 6 are both located between the two second clamping portions 22 .

[0055] The first clamping assembly 3 is opposite to the first clamping portion 11 in the X-axis direction. The first clamping assembly 3 includes a first clamping member 31 and a second clamping member 32 arranged along the Z-axis direction. At least one of the first clamping member 31 and the second clamping member 32 slides with the bracket body 1 along the Z-axis direction. When the first clamping assembly 3 is in the clamping state, the first clamping member 31 and the second clamping member 32 are close to and surround a third pipeline slot 33. The size of the third pipeline slot 33 is smaller than the size of the first pipeline slot 12. When the first clamping assembly 3 is in the separated state, the first clamping member 31 and the second clamping member 32 are separated.

[0056] The second clamping assembly 4 is arranged on the clamping member 2 and is opposite to the second clamping portion 22 in the X-axis direction. The second clamping assembly 4 includes a third clamping member 41 and a fourth clamping member 42 arranged along the Z-axis direction. At least one of the third clamping member 41 and the fourth clamping member 42 slides with the bracket body 1 along the Z-axis direction. When the second clamping assembly 4 is in the clamping state, the third clamping member 41 and the fourth clamping member 42 are close to and surround a fourth pipeline card groove 43. The size of the fourth pipeline card groove 43 is equal to the size of the third pipeline card groove 33. When the second clamping assembly 4 is in the separated state, the third clamping member 41 is separated from the fourth clamping member 42.

[0057] The third clamping assembly 5 is arranged along the X-axis with the first clamping assembly 3. The third clamping assembly 5 includes a fifth clamping member 51 and a sixth clamping member 52 arranged along the Z-axis. At least one of the fifth clamping member 51 and the sixth clamping member 52 slides with the bracket body 1 along the Z-axis. When the third clamping assembly 5 is in the clamping state, the fifth clamping member 51 and the sixth clamping member 52 are close together and enclose a fifth pipeline clamping slot 53. The size of the fifth pipeline clamping slot 53 is smaller than that of the third pipeline clamping slot 33. When the third clamping assembly 5 is in the separated state, the fifth clamping member 51 and the sixth clamping member 52 are separated. The first pipeline clamping slot 12, the third pipeline clamping slot 33, and the fifth pipeline clamping slot 53 are arranged coaxially.

[0058] The fourth clamping assembly 6 is disposed on the connecting member 2 and arranged along the X-axis with the second clamping assembly 4. The fourth clamping assembly 6 includes a seventh clamping member 61 and an eighth clamping member 62 arranged along the Z-axis. At least one of the seventh clamping member 61 and the eighth clamping member 62 slides with the bracket body 1 along the Z-axis. When the fourth clamping assembly 6 is in the clamping state, the seventh clamping member 61 and the eighth clamping member 62 are close to each other and enclose a sixth pipeline slot 63. The dimensions of the sixth pipeline slot 63 are equal to those of the fifth pipeline slot 53. When the fourth clamping assembly 6 is in the separated state, the seventh clamping member 61 and the eighth clamping member 62 are separated. The second pipeline slot 23, the fourth pipeline slot 43, and the sixth pipeline slot 63 are arranged coaxially.

[0059] The first pipeline slot 12, the second pipeline slot 23, the third pipeline slot 33, the fourth pipeline slot 43, the fifth pipeline slot 53 and the sixth pipeline slot 63 are all provided with guide openings 24 at the slot openings. The width of each guide opening 24 gradually increases from the end close to the corresponding pipeline slot to the end far away from the corresponding pipeline slot. The width of each slot is smaller than the diameter of the corresponding pipeline slot. During installation, the clamping part is inserted into the interior of the heat exchanger through the gap between the fins. The guiding effect of the guide opening 24 causes the clamping part to undergo elastic deformation, thereby clamping the pipeline slot into the pipeline of the heat exchanger. The provision of the guide opening 24 facilitates the installation of the temperature sensing package bracket. At the same time, the width of the slot is smaller than the diameter of the corresponding pipeline slot, which can prevent the temperature sensing package bracket from falling off the heat exchanger.

[0060] In this embodiment, each pipe slot is a circular hole with an opening. The diameter D1 of the first pipe slot 12 and the second pipe slot 23 is 7.6 mm, suitable for heat exchangers with a pipe diameter of φ8. The diameter D2 of the third pipe slot 33 and the fourth pipe slot 43 is 6.6 mm, suitable for heat exchangers with a pipe diameter of φ7. The diameter of the fifth pipe slot 53 and the sixth pipe slot 63 is 4.6 mm, suitable for heat exchangers with a pipe diameter of φ5. The third pipeline slot 33, the fourth pipeline slot 43, the fifth pipeline slot 53 and the sixth pipeline slot 63 are all surrounded by two semicircular grooves, and the two semicircular grooves are respectively located on the corresponding two clamping parts. For example, the third pipeline slot 33 includes a first semicircular groove 331 and a second semicircular groove 332, the first semicircular groove 331 is located on the first clamping part 31, and the second semicircular groove 332 is located on the second clamping part 32. When the first clamping component 3 is in the clamping state, the first semicircular groove 331 and the second semicircular groove 332 are combined into a circular third pipeline slot 33. When the first clamping component 3 is in the separated state, the first semicircular groove 331 and the second semicircular groove 332 are far away from each other, and a space is formed between the two for the heat exchanger pipeline to pass through without interference.

[0061] See also Figures 7 to 11 The clamping drive assembly 7 includes a coil (not shown), an elastic member 72, a valve core 73, and a valve seat 74. The valve seat 74 is mounted on the bracket body 1, and the valve core 73 is mounted on the clamping member 2. The valve core 73 can move along the valve seat 74 in the Z-axis direction. The ends of the elastic member 72 are connected to the bracket body 1 and the valve core 73, respectively. When the coil is energized, the valve core 73 is actuated, which drives the clamping member 2 to move in the positive direction of the Z-axis until the positive end of the clamping member 2 abuts the positive end of the Z-axis of the clamping member slot 14. At this point, the center distance between the second pipeline clamping slot 23 and the first pipeline clamping slot 12 is the first center distance. When the coil is de-energized, the elastic member 72 drives the valve core 73 to move in the negative direction of the Z-axis until the negative end of the Z-axis of the clamping member 2 abuts the negative end of the Z-axis of the clamping member slot 14. At this point, the center distance between the second pipeline clamping slot 23 and the first pipeline clamping slot 12 is the second center distance P2, which is smaller than the second center distance. Therefore, the switching of different pipeline center distances can be achieved by the solenoid valve principle, which has a simple structure and can achieve stable switching between the two positions of the clamping member 2. In this embodiment, the first center distance is 19.05mm, the second center distance is 22mm, and the elastic member 72 is a spring.

[0062] The four clamping drive components 8 are respectively used to drive the first clamping component 3, the second clamping component 4, the third clamping component 5 and the fourth clamping component 6 to switch between the clamping state and the separation state. The four clamping drive components 8 have the same structure. In this embodiment, only the clamping drive component 8 that drives the first clamping component 3 is used as an example to illustrate the structure.

[0063] The clamping drive assembly 8 includes a first electromagnet 81, a second electromagnet 82, a first attracted member 83, and a second attracted member 84. The bracket body 1 defines a first clamping slot 13 extending along the Z-axis. The first attracted member 83 and the second attracted member 84 both slidably engage with the first clamping slot 13. The first attracted member 83 is mounted on the first clamping member 31, and the second attracted member 84 is mounted on the second clamping member 32. Both the first attracted member 83 and the second attracted member 84 comprise magnets. The first electromagnet 81 and the second electromagnet 82 are respectively positioned at opposite ends of the first clamping slot 13. When the first clamping assembly 3 is in a clamping state, a forward current is passed through the first electromagnet 81 and the second electromagnet 82, and the repulsive force between the first electromagnet 81 and the magnet of the first attracted part 83 forces the first clamping part 31 to move toward the second clamping part 32, and the repulsive force between the second electromagnet 82 and the magnet of the second attracted part 84 forces the second clamping part 32 to move toward the first clamping part 31; when the first clamping assembly 3 is in a separated state, a reverse current is passed through the first electromagnet 81 and the second electromagnet 82, and the attractive force between the first electromagnet 81 and the magnet of the first attracted part 83 forces the first clamping part 31 to move back to the second clamping part 32, and the attractive force between the second electromagnet 82 and the magnet of the second attracted part 84 forces the second clamping part 32 to move back to the first clamping part 31.

[0064] The working method of the temperature sensing package bracket of this embodiment includes the following steps: First, obtain the pipe diameter of the heat exchanger and the center distance between adjacent pipes.

[0065] Next, based on the obtained pipe diameter and center distance values, the coils and corresponding electromagnets are controlled. For example, if a heat exchanger with a pipe diameter of φ8 and a center distance of 22 mm is required, the electromagnets of the four clamping drive assemblies 8 are all fed with reverse current, causing the four clamping assemblies to be separated. At the same time, the coils are de-energized, causing the clamping member 2 to move to its limit position in the negative direction along the Z axis under the action of its own weight and the restoring force of the elastic member 72. At this time, the temperature sensing package bracket is fixed by the first clamping portion 11 and the second clamping portion 22. If a heat exchanger with a pipe diameter of φ7 and a center distance of 19 mm is required, the electromagnets of the four clamping drive assemblies 8 are all fed with reverse current, causing the four clamping assemblies to be separated. 05mm heat exchanger, the electromagnets of the clamping drive assembly 8 that drive the first clamping assembly 3 and the second clamping assembly 4 are both passed with forward current, and the electromagnets of the clamping drive assembly 8 that drive the third clamping assembly 5 and the fourth clamping assembly 6 are both passed with reverse current, so that the first clamping assembly 3 and the second clamping assembly 4 are both in a clamping state, and the third clamping assembly 5 and the fourth clamping assembly 6 are both in a separated state. At the same time, the coil is energized, so that the valve core 73 drives the clamping part 2 to move along the Z-axis in the positive direction to the extreme position. At this time, the temperature sensing package bracket is fixed by the first clamping assembly 3 and the second clamping assembly 4. In addition, the temperature-sensing package bracket of this embodiment can also be applied to a heat exchanger with a tube diameter D of φ8 and a center distance P of 19.05 mm, a heat exchanger with a tube diameter D of φ7 and a center distance P of 22 mm, a heat exchanger with a tube diameter D of φ5 and a center distance P of 22 mm, and a heat exchanger with a tube diameter D of φ5 and a center distance P of 19.05 mm. Its working principle is similar to the principle applied to the above-mentioned heat exchanger with a tube diameter D of φ8 and a center distance P of 22 mm and a tube diameter D of φ7 and a center distance P of 19.05 mm, and will not be repeated here.

[0066] Alternatively, a code table can be set to specify a heat exchanger with a pipe diameter of φ8, corresponding to code a; a heat exchanger with a pipe diameter of φ5, corresponding to code b; a heat exchanger with a pipe diameter of φ7, corresponding to code c; a heat exchanger with a center distance P of 22mm, corresponding to code d; and a heat exchanger with a center distance P of 19.05mm, corresponding to code e. Through simple letter permutations and combinations, different D+P combinations of temperature-sensing bulb brackets required for different needs are obtained. The codes are set according to the needs in the production line, and the control module returns the processed code information, controlling the coil and corresponding electromagnet accordingly to obtain a matching temperature-sensing bulb bracket, thus achieving standardization and universalization of the product. Therefore, by entering a simple code, the problem of easily misusing temperature-sensing bulb brackets in the prior art is solved. Unlike existing conventional designs that are designed for specific purposes, the present invention enables a single temperature-sensing bulb bracket to be used on heat exchangers of different specifications, completely replacing all currently existing temperature-sensing bulb brackets.

[0067] As can be seen from the above, the existing temperature-sensing bulb brackets are difficult to quickly distinguish with the naked eye for temperature-sensing bulb brackets of the same structure used in different heat exchangers due to the similar sizes of the pipe slots and the similar sizes of the pipe center distances. In the actual production process, the wrong use will occur from time to time. Some temperature-sensing bulb brackets cannot be inserted into the heat exchanger; some temperature-sensing bulb brackets are not stable after being inserted into the heat exchanger, and there is a risk of falling off. The present invention adapts to a variety of heat exchanger pipe diameters through the cooperation of the clamping component and the first clamping part, and adapts to a variety of heat exchanger pipe center distances through the sliding cooperation of the clamping part and the bracket body, thereby improving the versatility of the temperature-sensing bulb bracket, reducing the quality risks of wrong use, improving product reliability, and reducing mold costs.

[0068] In addition, the number of first clamping parts may be one or more than two, and each first clamping part may be spaced apart along the X-axis direction. The number of second clamping parts may be one or more than two, and each second clamping part may be spaced apart along the X-axis direction. The temperature sensing package bracket may not be provided with a third clamping assembly and a fourth clamping assembly, that is, it is only composed of a bracket body, a clamping part, a first clamping assembly and a second clamping assembly, but this will reduce the versatility of the temperature sensing package bracket. The temperature sensing package bracket may also be provided with more clamping assemblies, for example, more than three clamping assemblies are provided between the two first clamping parts, and / or more than three clamping assemblies are provided between the two second clamping parts, and the size of the pipeline slots on the corresponding clamping assemblies may also be set as needed to further improve the versatility of the temperature sensing package bracket. In addition, in order to better define the positions of the first clamping assembly, the second clamping assembly, the third clamping assembly, and the fourth clamping assembly more accurately, and to ensure that the corresponding pipeline slots can be coaxial with the first pipeline slot or the second pipeline slot when the four clamping assemblies are in the clamping state, for example, a limit block can be set in the middle of the first clamping slot. When the first clamping assembly is in the clamping state, the first clamping member is located on the positive side of the Z axis of the limit block and is limited in position with the limit block on the Z axis. The second clamping member is located on the negative side of the Z axis of the limit block and is limited in position with the limit block on the Z axis. Similarly, the two clamping members in the second clamping assembly, the two clamping members in the third clamping assembly, and the two clamping members in the fourth clamping assembly can be limited. The above changes can also achieve the purpose of the present invention.

[0069] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
