Abstract
Description
Technical Field
[0001] This invention relates to the field of instrument connection technology, and specifically to a high-efficiency heat dissipation connector for pressure gauges. Background Technology
[0002] Pressure gauges are widely used in many fields such as industrial process control, energy, chemical industry, and water treatment. They are usually installed on pipelines with a connector to monitor the fluid pressure in pipelines or equipment in real time. They are the first point of contact between the instrument and the high-temperature process medium. When they come into contact with high-temperature media, the internal components of the instrument will overheat, affecting the measurement accuracy or even burning out. Although heat dissipation can be improved by lengthening the connector and adding external heat dissipation devices, problems still exist in actual applications.
[0003] For example, in actual operation, pressure instrument connectors often suffer from low heat dissipation efficiency when dealing with high-temperature media, making it difficult to achieve efficient and reliable thermal management within a limited space without relying on a complex external cooling system. Therefore, a high-efficiency heat dissipation connector for pressure instruments is needed. Summary of the Invention

Detailed Implementation
[0064] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.
[0065] like Figures 1 to 8 As shown, a high-efficiency heat dissipation connector for pressure instruments includes a pipe threaded joint 1, a filter screen 2 at the bottom of the pipe threaded joint 1, a recovery tray 4 sleeved on the outside of the pipe threaded joint 1, an L-shaped pipe 3 fixedly installed between the pipe threaded joint 1 and the recovery tray 4, a main body rod 5 and a heat dissipation coil 6 at the center of the recovery tray 4, with the heat dissipation coil 6 located outside the main body rod 5, a mesh reinforcing rib 7 at the top of the main body rod 5, a flange mounting plate 8 penetrating above the mesh reinforcing rib 7, a first protective cover 9 above the flange mounting plate 8, a heat-conducting base 10 at the top of the first protective cover 9, and a pressure instrument 11 fixedly installed above the heat-conducting base 10. The connector also includes:
[0066] The heat dissipation section is located above the pipe threaded joint 1 to improve the heat dissipation efficiency around the pipe workpiece.
[0067] The hot end heat dissipation part includes a condenser and a first heat dissipation component. The condenser is disposed inside the recovery tray 4 and is connected to the first heat dissipation component. The first heat dissipation component is disposed in the middle of the recovery tray 4.
[0068] The middle heat dissipation section is located on the outside of the main body rod 5 and above the recovery plate 4 to improve heat dissipation in the middle.
[0069] The mid-end heat dissipation section includes a uniform heat dissipation component and a second heat dissipation component. The uniform heat dissipation component is disposed inside the main body rod 5 and is connected to the main body rod 5. The second heat dissipation component is disposed outside the main body rod 5.
[0070] The cold end heat dissipation section is located in the center of the flange mounting plate 8 to improve heat dissipation around the pressure gauge 11;
[0071] The cold end heat dissipation part includes a heat-dissipating component and a third heat dissipation component. The heat-dissipating component is located above the main body rod 5 and is connected to the third heat dissipation component. The third heat dissipation component is located below the heat-conducting base 10 and inside the first protective cover 9.
[0072] Specifically, the L-shaped pipe 3 is connected to the pipe threaded joint 1 to improve reliability; the filter screen 2 is convenient to be inserted into the high-temperature medium pipe workpiece to prevent the entry of particulate matter; the heat dissipation coil 6 cooperates with the main rod 5 to diffuse heat outward and form heat dissipation; the mesh reinforcing rib 7 penetrates through the flange mounting plate 8 and extends into the interior of the first protective cover 9 to form an auxiliary heat dissipation treatment for the pressure gauge 11.
[0073] In actual use, the bottom of the pipe threaded connector 1 and the filter screen 2 are first inserted downwards onto the high-temperature pipe workpiece, and then the top is connected to the outside of the main body rod 5. The pipe threaded connector 1 is connected to the pressure instrument 11 through the mesh reinforcing rib 7 and the heat-conducting base 10. When the heat is transferred through the pipe workpiece below, it is contacted by the first heat dissipation fin 13 inside the pipe threaded connector 1, and then dissipated again through the second heat dissipation fin 15 to reduce the high temperature and perform primary heat dissipation. Then, under the action of the connection, the heat is gradually conducted to the main body rod 5. With the assistance of the heat dissipation coil 6 on the outside of the main body rod 5, the middle heat dissipation fin 35, the hole 25, and the inner middle rod 31 and the support strip 24, the heat is further intercepted, which greatly improves the heat dissipation effect. Finally, the heat is dissipated through the cold heat dissipation fin 32. According to the constructed progressively increasing heat dissipation structure, the heat conducted to the pressure instrument 11 is minimized.
[0074] Since the ambient temperature of the pressure gauge 11 is relatively low, the condensate is mainly generated near the cooling fins 32 inside the first protective cover 9. Water vapor in the air condenses into water on the surface of the cooling fins 32 at a lower temperature. The condensate is guided along the guide groove 33 and the limiting hole 34 on the flange mounting plate 8, and finally falls into the recovery plate 4 for unified collection and discharge.
[0075] like Figures 2 to 4 As shown, the condenser includes:
[0076] Sleeve 12 is located on the outside of the main body rod 5;
[0077] The second protective cover 14 is positioned above the sleeve 12;
[0078] The guide tube 16 is installed inside the sleeve 12.
[0079] The first heat dissipation component includes:
[0080] The first heat dissipation fin 13 is located below the sleeve 12;
[0081] The top inner side of the sleeve 12 is provided with a first groove that matches the second protective cover 14;
[0082] The second heat dissipation fin 15 is located below the second protective cover 14;
[0083] A second groove adapted to the first heat dissipation fin 13 is provided on the inner side below the sleeve 12;
[0084] Specifically, the sleeve 12 is located inside the recycling tray 4, and a through groove is provided in the center. The center of the first heat dissipation fin 13 is adapted to the outer side of the main body rod 5. The main body rod 5 passes through the inside of the first heat dissipation fin 13 and is connected to the pipe threaded joint 1. The four corners of the first heat dissipation fin 13 and the second heat dissipation fin 15 are provided with arc corners so that the condensate can flow downward. The bottom of the sleeve 12 and the second protective cover 14 are both provided with guide grooves.
[0085] In actual operation, when the high-temperature medium inside the pipe workpiece surges upward, the heat will first come into contact with the first heat dissipation fin 13 on the outside of the main body rod 5. The high temperature is initially reduced by the heat dissipation fin 13 spreading outward, and then conducted to the inside of the second protective cover 14 through the sleeve 12. After contact with the second heat dissipation fin 15, the heat is diffused again. It has the function of cooling before entering the connector entrance. The temperature difference is the largest, the heat dissipation is obvious, and it prevents more heat from being conducted later, thus playing the role of protecting the temperature by cooling it down first.
[0086] During installation, the first heat dissipation fin 13 needs to be sleeved on the outside of the main body rod 5 first, and then the second heat dissipation fin 15 is placed in the sleeve 12 in sequence. The second heat dissipation fin 15 is located above the first heat dissipation fin 13. At this time, the installation is completed by screwing the second protective cover 14 into the first groove above the sleeve 12. When disassembling, it can be quickly disassembled by rotating to facilitate subsequent disassembly and cleaning.
[0087] When encountering harsh environmental conditions, as high temperatures rise, they may be accompanied by polluting particles. These particles come into contact with the lower surface of the recycling tray 4 and are blocked by the recycling tray 4.
[0088] When condensation occurs on the second heat dissipation fin 15 and the first heat dissipation fin 13, the water will flow along the arc angle to the upper groove on the inner wall of the sleeve 12, and enter the interior of the guide pipe 16 through the groove, and then flow into the collection tray 4 to form a collection, so as to ensure that the condensation is treated in time. It should be noted that the upper groove of the sleeve 12 is an inclined design with one side higher and the other side lower, and it contacts the guide pipe 16.
[0089] like Figures 6 to 7 As shown, the uniform component includes:
[0090] The middle rod 31 is located inside the main rod 5;
[0091] Guide rods 27, having multiple rods, are fixedly installed on the outside of the card plate 26;
[0092] Card plate 26 is located on the outside of the middle rod 31;
[0093] Dust-proof components are installed on the outside of the card plate 26 to block the heat dissipation holes;
[0094] Dust-proof components include:
[0095] Reset piece 28 is located on the outside of guide rod 27;
[0096] Memory alloy springs 29, in multiple forms, are disposed on the inner wall of the main body rod 5;
[0097] The sealing plate 30 is set at one end of the memory alloy spring 29 and is located outside the guide rod 27;
[0098] The second heat sink includes:
[0099] Multiple holes 25 are formed on the outer surface of the main body rod 5 and located between the shape memory alloy springs 29;
[0100] There are multiple mid-end heat dissipation fins 35, which are located on the outside of the main body rod 5.
[0101] Specifically, the guide rod 27 facilitates faster heat dissipation and allows heat to enter the main body rod 5; the clamping plate 26 facilitates the installation of the guide rod 27; the middle rod 31 helps to stabilize multiple guide rods 27; the main body rod 5 is used for vertical connection to improve reliability; the reset plate 28 provides guidance for the memory alloy spring 29, preventing damage during long-term elongation or shortening of the spring and improving stability; the sealing plate 30 fills the holes 25 on the outer surface of the main body rod 5 by default, ensuring the smoothness of the outer side of the main body rod 5 and preventing dust accumulation. Dust entering the main body rod 5 causes dirt; the middle heat dissipation fins 35 are spiral heat dissipation fins, the spiral shape increases the airflow path and turbulence, resulting in good heat dissipation. At the same time, without sharp right angles, the stress distribution is more uniform; the holes 25 facilitate direct flushing of the heat dissipation coil 6, reducing dust that may adhere to the outside of the heat dissipation coil 6; the compression memory alloy spring 29 is for low-temperature reset. When reset, it contracts and pulls the sealing plate 30 to close the hole 25, which serves as a dust prevention function; at high temperatures, it extends and pushes the sealing plate 30 to open the hole 25, which serves as an opening for heat dissipation.
[0102] In practical applications, after the main body rod 5 is inserted into the first heat dissipation fin 13, heat enters the main body rod 5 through the transfer effect. The heat diffusion is accelerated through the gap between multiple guide rods 27 and dissipated outward through the holes 25. In addition, the external middle heat dissipation fin 35 will uniformly process the heat. Through distributed heat dissipation, it is convenient to reduce high temperature and achieve the effect of lowering the temperature, which is conducive to improving the heat dissipation effect.
[0103] If the equipment is not working or the environment is cold, when the temperature is below a certain set value, such as 50°C, the spring contracts and pulls the sealing plate 30 to block the hole 25, preventing dust from entering. This facilitates the removal of dust from the outer surface of the main body rod 5, thus playing an auxiliary role in dust prevention.
[0104] When the temperature rises to the operating temperature, such as above 80°C, the shape memory alloy spring 29 is in an extended state, pushing the sealing plate 30 to open the hole 25. The opening of the hole 25 enhances heat dissipation and ensures that heat can be dissipated smoothly.
[0105] like Figures 3 to 5 As shown, the heat-dissipating component includes:
[0106] The telescopic mounting cylinder 20 is installed inside the recycling tray 4;
[0107] Temperature sensor 19 is located inside the recycling tray 4 and outside the telescopic mounting cylinder 20;
[0108] The electric telescopic pole 21 is installed inside the telescopic mounting cylinder 20;
[0109] The twist bar 23 is installed through the outer side of the telescopic mounting cylinder 20;
[0110] Support strip 24 is located outside the twist strip 23 and inside the recycling tray 4;
[0111] Cantilever board 22 is installed above the electric telescopic pole 21;
[0112] Specifically, a processor is provided on the outside of the telescopic mounting cylinder 20 to sense the power of the temperature sensor 19 and facilitate timely driving processing; the temperature sensor 19 is located inside the recycling tray 4 to monitor the heat dissipation efficiency. If the temperature of the middle heat dissipation fins 35 is consistently high, it indicates that the heat dissipation may be poor due to dust accumulation, and the processor will be triggered to drive the electric telescopic rod 21 to clean the dust.
[0113] The electric telescopic rod 21 is equipped with a motor at the bottom, which converts electrical energy into rotational mechanical energy to facilitate the timely extension of the electric telescopic rod 21. This is existing technology and will not be described in detail. The end of the cantilever plate 22 is designed with an arc shape to match the shape of the heat sink 6, ensuring sufficient contact during operation without damaging the heat sink 6.
[0114] In practical applications, since the heat dissipation coil 6 is located on the outside of the main rod 5, dust tends to accumulate on the outside over time. Therefore, when the temperature of the heat dissipation fins 35 in the middle of the recovery tray 4 remains high, an electrical signal is fed back to the processor. The processor then drives the electric telescopic rod 21 upward, which pushes the lifting plate 22 upward to squeeze the heat dissipation coil 6. The heat dissipation coil 6 vibrates after being squeezed, and the vibration force shakes the dust off the outside into the recovery tray 4, thus reducing the amount of dust on the outside of the heat dissipation coil 6. The support strip 24 is used to support the telescopic mounting cylinder 20 to prevent instability and improve reliability.
[0115] like Figures 1 to 2 , Figure 8 As shown, the third heat sink includes:
[0116] Cooling fins 32 are disposed inside the first protective cover 9;
[0117] The flow guide 33 is located below the first protective cover 9;
[0118] Limiting hole 34 is located inside flange mounting plate 8;
[0119] The flange mounting plate 8 has a through hole in the center that connects to the mesh reinforcing rib 7;
[0120] The mesh reinforcing rib 7 has multiple gaps inside;
[0121] The threaded tube 36 is rotatably positioned at the center of the heat-conducting base 10;
[0122] The center of the heat-conducting base 10 is provided with an internal thread that is compatible with the threaded tube 36.
[0123] Specifically, the flange mounting plate 8 has limit holes 34 on both sides inside, which are aligned with the vertical guide groove 33; the mesh reinforcing rib 7 is connected to the heat dissipation fins 32, which facilitates the transfer of heat to the area around the middle rod 31, while improving the stability of the connection with the main rod 5 and dissipating heat in time; the threaded tube 36 facilitates the installation of the first protective cover 9 at the bottom of the heat-conducting base 10, making it easy to disassemble or install.
[0124] In practical applications, when the connector body rod 5 conducts heat from the pipe threaded joint 1 to the cold end heat-conducting base 10, the cold heat dissipation fins 32 dissipate the accumulated heat into the air, thereby completing the heat dissipation of the cold end; when condensate is generated, it moves along the outer edge of the cold heat dissipation fins 32 to both sides, flows down through the guide groove 33, and then flows through the flange mounting plate 8 into the recovery plate 4, thereby completing the recovery of condensate.
[0125] Working principle: The heat dissipation part at the hot end is the first line of defense for the connector when it comes into contact with high-temperature media. It is located above the pipe threaded joint 1 and inside the recovery tray 4.
[0126] Heat interception and initial diffusion: When the heat of the high-temperature medium is conducted upward through the pipe workpiece, it is first contacted by the first heat dissipation fin 13 located at the front end. These fins have a large surface area and can quickly absorb heat and diffuse it to the outside air to achieve initial cooling.
[0127] Secondary heat dissipation and thermal isolation: The remaining heat is conducted through the sleeve 12 to the area of the second protective cover 14 inside, and then dissipated again by the second heat dissipation fins 15. This design takes advantage of the largest temperature difference at the inlet, and performs strong cooling before the heat enters the connector body, effectively reducing the total amount of heat conducted backward;
[0128] Physical protection and redundant design for condensate drainage:
[0129] Particulate protection: The recovery tray 4 acts as a physical barrier to block contaminant particles that rise with the hot airflow, preventing them from entering the core of the connector.
[0130] Although condensate is mainly generated at the cold end, the edges and corners of the heat dissipation fins at the hot end are designed with rounded corners, and the bottom of the sleeve 12 and the second protective cover 14 are also provided with guide grooves. In case of condensate, it can be ensured that it flows smoothly into the recovery tray 4 along the guide pipe 16 to avoid local liquid accumulation.
[0131] The heat from the primary cooling system is conducted upwards along the main body rod 5 and enters the middle cooling section. This section is the main area for heat dissipation and integrates intelligent dustproof functionality.
[0132] After the heat enters the main rod 5, it is dispersed by the internal structure consisting of the central rod 31 and multiple guide rods 27, which accelerates the uniform distribution of heat in the rod body and lays the foundation for rapid heat dissipation.
[0133] The evenly distributed heat dissipates outward through the outer wall of the main body rod 5 and the open holes 25. The spirally arranged mid-end heat dissipation fins 35 on the outer wall greatly increase the contact area with the air and the turbulence effect, achieving efficient heat dissipation. At the same time, the heat dissipation coil 6 also works in conjunction to further dissipate the heat outward.
[0134] Operating at high temperatures >80℃: When the temperature rises to the operating threshold, such as above 80℃, the shape memory alloy spring 29 expands due to heat, generating thrust and pushing the sealing plate 30 to move, thereby opening the hole 25 on the wall of the main rod 5. At this time, the heat dissipation path is unobstructed, prioritizing heat dissipation efficiency and exhibiting intelligent self-adaptive characteristics.
[0135] Low Temperature (<50℃) in Dormant State: When the device stops working and the temperature drops below the low temperature threshold (e.g., below 50℃), the memory alloy spring 29 retracts and resets, pulling the sealing plate 30 back to its original position, tightly sealing the hole 25. This design perfectly resolves the contradiction between efficient heat dissipation and long-term dust prevention, protecting the internal cleanliness of the connector during non-operating periods.
[0136] The residual heat reaching the top of the connector is finally treated in the cold end heat dissipation section, which also solves the problem of condensation caused by heat dissipation.
[0137] Heat is conducted to the cooling fins 32 through the mesh reinforcing ribs 7. These fins are located inside the first protective cover 9, below the pressure gauge 11, dissipating the last of the heat into the air and ensuring that the heat transferred to the mounting base of the pressure gauge 11 is minimized, providing it with an optimal operating temperature environment.
[0138] Because the temperature at the pressure gauge 11 end is relatively the lowest, water vapor in the air easily condenses into water on the surface of the cooling fins 32. The condensate flows along the edge of the fins to the guide groove 33 at the bottom of the first protective cover 9, and then drips down through the limiting hole 34 on the flange mounting plate 8, eventually flowing into the collection tray 4. The collection tray 4 serves to collect and drain the condensate, preventing moisture from corroding parts or dripping and causing other damage.
[0139] To address the issue of dust accumulation on the outside of the heat sink coil 6 during long-term use, the connector is equipped with an automatic dust removal system based on temperature feedback.
[0140] Temperature sensor 19, located inside the recycling disk 4, continuously monitors the temperature of the mid-range heat dissipation area. When the temperature is detected to be abnormally high, the processor determines that the decrease in heat dissipation efficiency is likely due to dust accumulation.
[0141] The processor then activates the electric telescopic lever 21, pushing it upwards. The lifting plate 22 at the top of the electric telescopic lever 21 has an arc-shaped end to adapt to the shape of the heat sink 6 and push it upwards, causing it to vibrate slightly. This shakes the dust attached to its outer surface into the collection tray 4 below, where it is discharged from the system along with the condensate.
[0142] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
