Description

Technical Field

[0001] This utility model belongs to the technical field of battery thermal management system performance testing, specifically relating to an integrated probe structure for TPMS thermal management system testing. Background Technology

[0002] The integrated probe structure for TPMS thermal management system testing is a new type of detection device developed to meet the needs of industrial process control, energy metering, medical equipment and other fields for "synchronous detection and compact installation" of fluid temperature and flow. It integrates the flow monitoring probe (placed at the center of the bottom of the probe integration base) and multiple infrared temperature probes (equally distributed on the outside of the flow probe) into the same housing, and with the help of hollow cable tube, mounting flange and data collection host, it realizes the function of "one-time installation and dual detection". Compared with the traditional separate infrared thermometer and flow meter, it greatly reduces the installation space occupied, improves the synchronization of temperature and flow data, and effectively adapts to the use requirements of narrow installation environment and high-precision detection scenarios.

[0003] However, existing integrated probes still face significant challenges in TPMS thermal management system testing for scenarios such as new energy vehicle battery packs and computing servers: First, the internal space of battery packs is extremely limited, requiring test probes to be miniaturized (typically with a diameter less than 30mm), making it difficult to embed traditional probes; second, the performance evaluation of TPMS flow channels is highly dependent on the highly synchronized acquisition of inlet and outlet temperature differences and flow rates (timing error must be ≤1ms), and any data asynchrony will lead to distortion in the calculation of thermal resistance and flow resistance; finally, existing probe structures mostly rely on a single rubber sealing gasket in conjunction with the mounting flange to achieve sealing, which is insufficient to meet the leakage prevention requirements under complex operating conditions. Specifically, in existing structures, a single sealing gasket can only cover the mounting flange. The contact surface with the mounting surface, the area around the pre-drilled holes on the mounting flange for fixing, the flange edge, and the connection between the probe center and the mounting surface are prone to forming sealing blind spots due to the inability of the gasket to accurately cover them. When the probe is used in high-pressure fluid or corrosive fluid scenarios, the fluid can easily seep through these blind spots, which may not only damage the equipment but also cause safety accidents. In actual installation, the pipe mounting surface often has minor dents, scratches, and other defects. Existing rigid gaskets cannot adaptively fill these defects, resulting in small gaps between the gasket and the mounting surface. At the same time, the mounting surface dimensions of different pipe specifications vary, and a single-size gasket is difficult to be compatible with multiple installation scenarios, requiring the customization of different specifications of seals, which increases the cost of use. Utility Model Content

[0004] The purpose of this invention is to provide an integrated probe structure for testing TPMS thermal management systems, in order to solve the problems mentioned in the background art, such as the inability of existing probes to adapt to the small space of battery packs, poor data synchronization leading to inaccurate TPMS performance evaluation, and insufficient installation sealing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated probe structure for testing a TPMS thermal management system, comprising a hollow cable tray and a probe integration base disposed at the bottom end of the hollow cable tray. A flow monitoring probe is disposed at the center of the bottom end of the probe integration base.

A mounting flange is welded and fixed to the upper outer side of the center of the hollow cable tray. An installation encryption device is disposed on the outer wall of the bottom end of the mounting flange. The maximum outer diameter of the probe integration base is not greater than 25mm. The data synchronization sampling rate of the flow monitoring probe and the infrared temperature measuring probe is ≥1kHz.

[0006] Preferably, the mounting encryption device includes a rubber sealing gasket, which is completely fitted to the outer wall of the bottom end of the mounting flange. The thickness of the rubber sealing gasket is less than the thickness of the mounting flange, and the rubber sealing gasket is flush with the circular outer wall of the mounting flange. The rubber sealing gasket and the inner side of the mounting flange near the circular outer side are also connected by multiple pre-drilled holes at equal intervals, and the rubber sealing gasket and the pre-drilled holes inside the mounting flange overlap vertically.

[0007] Preferably, the installation encryption device further includes anti-displacement rubber plugs and anti-displacement sockets. Multiple anti-displacement sockets are equidistantly arranged inside the lower half of the installation flange. Multiple anti-displacement rubber plugs are equidistantly arranged on the top of the rubber sealing gasket. The multiple anti-displacement rubber plugs are respectively inserted into the anti-displacement sockets corresponding to their positions. The tops of the multiple anti-displacement rubber plugs are all hemispherical.

[0008] Preferably, the installation encryption device further includes annular encryption airbag A, annular encryption airbag B, and annular encryption airbag C. The rubber sealing gasket is provided with annular encryption airbag A near the outer side of the circle and located on the outer wall of the bottom end. Annular encryption airbag B is provided on the inner side of the annular encryption airbag A. Annular encryption airbag C is provided on the inner side of the annular encryption airbag B.

[0009] Preferably, the annular encrypted airbag A and the annular encrypted airbag B are located on the outer and inner sides of the circular structure formed by multiple pre-drilled holes, respectively, and the cross-sectional shape of the annular encrypted airbag A, the annular encrypted airbag B and the annular encrypted airbag C are all semi-circular.

[0010] Preferably, the top ends of the annular encrypted airbags A, B, and C are all sealed to the outer wall of the bottom end of the rubber sealing gasket, so that the annular encrypted airbags A, B, and C are in a sealed state, and the diameters of the annular encrypted airbags A, B, and C increase sequentially.

[0011] Preferably, the vertical height of the flow monitoring probe is greater than that of the infrared temperature measuring probe, and the top of the probe integration base is also provided with a encryption sleeve, which is sealed to the outside of the hollow cable tube.

[0012] Preferably, the top of the hollow cable tray is fixed with a data collection host by a flange and screws. Multiple control buttons are provided on the front side of the top center of the data collection host, and a small display screen is provided inside the rear side of the top center of the data collection host.

[0013] Compared with the prior art, this utility model provides an integrated probe structure for testing TPMS thermal management systems, which has the following advantages:

[0014] This invention, through its miniaturized design (probe integrated base diameter ≤25mm) and integrated structure, can penetrate into narrow spaces such as inside a battery pack and directly connect to the TPMS flow channel interface. This solves the problem of traditional testing equipment being too bulky to install, enabling in-situ, real-world performance testing of the TPMS thermal management system. The internal FPGA signal processing unit achieves high-synchronization acquisition of infrared temperature and flow data (synchronization sampling rate ≥1kHz, timing error ≤1ms), providing a reliable data foundation for accurately calculating key performance indicators such as thermal resistance, flow resistance, and heat dissipation efficiency of the TPMS flow channel, greatly improving testing accuracy and reliability.

[0015] This invention adds a novel mounting encryption device to the bottom of the mounting flange used for installing the integrated probe for TPMS thermal management system testing. This device significantly improves the overall sealing reliability, structural stability, and operational adaptability of the probe after installation, effectively solving the problems of fluid leakage, poor installation adaptability, and high maintenance costs that are prone to occur in traditional installation methods. It provides a solid guarantee for the probe to accurately monitor temperature and flow data. In this mounting encryption device, the encryption structure composed of annular encryption airbags A, B, and C plays a core role. Airbag B and annular encrypted airbag C are nested in an outer, middle and inner configuration, respectively covering the outer and inner sides of the installation pre-drilled hole and the central installation area of ​​the probe, forming a three-dimensional sealing barrier without dead angles. The outer annular encrypted airbag A can prevent fluid from seeping from the edge of the installation flange, the middle annular encrypted airbag B can fill the sealing blind spot around the installation pre-drilled hole, and the inner annular encrypted airbag C protects the central gap between the probe and the installation surface. Even in a high-pressure fluid environment, the airbags fit tightly against the installation surface through elastic deformation, greatly improving the sealing performance and minimizing the risk of leakage, meeting the needs of chemical, medical and other scenarios with stringent fluid sealing requirements.

[0016] Furthermore, the annular encrypted airbags A, B, and C adopt a semi-circular cross-section design, which maximizes the contact area with the mounting surface. When there are minor dents, scratches, or other defects on the mounting surface, the airbags can fill the defective areas with their own elasticity, avoiding the sealing failure caused by the poor fit of traditional rigid gaskets. Moreover, the diameters of the annular encrypted airbags A, B, and C increase sequentially. After installation, the airbags with increasing diameters will form a structure that gradually supports the outside from the inside out. The smaller diameter airbags on the outside can fit against the flange edge, providing lateral support for the flange and preventing slight deformation of the flange due to uneven stress. The larger diameter airbags in the middle and on the inside can push upwards to tighten the connection between the mounting flange and the probe integrated seat, enhancing the longitudinal stability of the overall structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-5The diagram illustrates an integrated probe structure for testing a TPMS thermal management system. It includes a hollow cable tray 5 and a probe integration base 3 located at the bottom of the hollow cable tray 5. The hollow cable tray 5 serves as the core cable routing channel, centrally housing the signal cables of the probe module and the connection cables of the data acquisition host 8, preventing the cables from being exposed to environmental corrosion or external damage. The hollow design also facilitates future cable inspection and replacement, significantly improving the convenience of cable maintenance compared to distributed wiring. The probe integration base 3 provides a unified mounting surface for the flow monitoring probe 1 and the infrared temperature measurement probe 2, ensuring high physical integration between the two and laying the structural foundation for synchronous data acquisition. A flow monitoring probe 1 is installed at the center of the bottom of the seat 3. Multiple infrared temperature probes 2 are equidistantly arranged on the outer side of the circular flow monitoring probe 1. The core advantage of this layout is that it enables synchronous detection on the same cross section. The flow monitoring probe 1 is located in the center and can capture the fluid velocity in the central area of ​​the pipe (the velocity in this area is the most stable, which can improve the accuracy of flow detection). The infrared temperature probes 2 are equidistantly distributed on the outer side. This layout is designed to achieve synchronous data acquisition on the same detection cross section. It is the key to accurately evaluating the heat dissipation and flow resistance performance of the TPMS flow channel. As a key embodiment of this utility model, the probe structure is designed to test the performance of the gradient TPMS liquid cooling plate as described in the claim. Its miniaturized probe integrated seat (3) (outer diameter ≤ 25 mm) can be embedded in the narrow space inside the battery pack and directly connected to the test interface of the TPMS flow channel. The data collected by the flow monitoring probe (1) and the infrared temperature probe (2) are synchronously processed by the internal FPGA signal processing unit (synchronous sampling rate ≥ 1 kHz) and finally used to calculate and display the core performance parameters such as thermal resistance and heat dissipation efficiency of the TPMS cold plate.

[0025] like Figure 1 and Figure 2As shown, the vertical height of the flow monitoring probe 1 is greater than that of the infrared temperature probe 2. This design is intended to adapt to the fluid flow characteristics. This height difference is crucial for accurately measuring the core parameters of complex fluids within the TPMS channel. The fluid inside the pipe exhibits a boundary layer effect; the fluid velocity near the inner wall is slower, and the temperature is easily affected by the pipe wall. The flow monitoring probe 1, being more prominent (higher vertical height), can penetrate deeper into the mainstream fluid area, reducing the interference of the boundary layer on flow detection. The infrared temperature probe 2, being lower in height, can cover a wider cross-sectional area while avoiding disturbances in the mainstream area. This reasonable height difference structurally balances the different installation requirements of flow and temperature detection, ensuring that the two detection functions do not interfere with each other and maximizing detection accuracy. The probe integration base 3 also has a sealing sleeve 4 at its top, which is sealed to the outside of the hollow cable tray 5. The core function of the sealing sleeve 4 is to achieve a sealed protection at the connection between the probe integration base 3 and the hollow cable tray 5. In principle, this is achieved through sealing... The sleeve connection prevents impurities such as fluid and dust from seeping into the probe through the gap between the two, avoiding their impact on the core components of the flow monitoring probe 1 and the infrared temperature probe 2. The reinforced sleeve 4 also enhances the structural stability of the connection, reducing loosening caused by pipeline vibration. Compared to traditional threaded connections that rely solely on thread sealing, this design offers a dual improvement in sealing and stability. A mounting flange 7 is welded to the upper outer side of the center of the hollow cable tray 5. This welded connection provides higher structural strength and sealing compared to bolted connections, withstanding high-pressure impacts and long-term vibrations from pipeline fluids. This prevents gaps between the mounting flange 7 and the hollow cable tray 5. The mounting flange 7 serves as the connection interface between the probe and the pipeline, adaptable to different specifications of pipeline flanges. Rapid probe installation is achieved through bolt tightening. In principle, the standardized connection characteristics of the flange reduce the difficulty of matching the probe to the pipeline, improving installation efficiency. Simultaneously, the rigid structure of the flange provides stable support for the entire probe, reducing probe swaying within the pipeline.

[0026] like Figure 1 and Figure 2As shown, the top of the hollow cable tray 5 is fixed with a flange and screws to a data acquisition host 8. The data acquisition host 8 integrates a signal processing unit, which can ensure high synchronization of temperature and flow data acquisition (timing error ≤1ms) to meet the stringent requirements of TPMS performance testing for data accuracy. The flange and screw fixing method facilitates the disassembly and maintenance of the data acquisition host 8. Compared with welding fixation, if the host fails later, it can be quickly disassembled and replaced, reducing maintenance costs. Multiple control buttons 9 are set on the front side of the top center of the data acquisition host 8, and a small display screen 10 is set inside the rear side. The control buttons 9 allow operators to set detection parameters on site (such as temperature alarm threshold, flow unit switching, etc.) without connecting to a host computer, which can complete basic operations and improve ease of use. The small display screen 10 can display the detection data of temperature and flow in real time, allowing operators to intuitively grasp the detection status. In principle, the signal processing unit inside the host converts the raw signal transmitted by the probe into visualized data and displays it on the screen. At the same time, the button operation signal can be directly fed back to the processing unit to realize rapid parameter adjustment, forming a closed loop of on-site operation and real-time display, improving the real-time performance and controllability of the detection.

[0027] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, to further improve the sealing and stability of the installation, an installation encryption device 6 is provided on the bottom outer wall of the mounting flange 7. This device is crucial to ensuring the probe operates without leakage. The installation encryption device 6 includes a rubber gasket 11, which is completely fitted to the bottom outer wall of the mounting flange 7 and flush with the circular outer wall of the mounting flange 7. This complete fit maximizes the contact area between the gasket and the flange. In principle, it utilizes the elastic deformation properties of rubber to fill the tiny gaps between the flange and the mounting surface, preventing fluid from penetrating from the contact surface. The thickness of the rubber gasket 11 is less than that of the mounting flange 7, which avoids uneven stress on the flange due to an excessively thick gasket and prevents flange deformation during bolt tightening. Simultaneously, it works in harmony with the flange... The flush outer wall avoids installation interference caused by the protruding gasket, ensuring a flat and snug fit on the mounting surface. Compared to gaskets that are too thick or mismatched in size, the sealing reliability and installation compatibility are significantly improved. In addition, the rubber gasket 11 and the mounting flange 7 are connected at equal intervals near the circular outer side with multiple pre-drilled holes, and the pre-drilled holes inside both are vertically aligned. The advantage of this positional relationship is that it ensures that the bolts can pass through the gasket and the flange accurately, avoiding uneven pressure on the gasket due to hole misalignment. In principle, by aligning the holes, the bolt tightening force is evenly transmitted to the gasket, causing the gasket to deform evenly and further improving the sealing effect. At the same time, the equidistant pre-drilled holes can balance the force on the flange and reduce flange damage caused by local stress concentration.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, multiple anti-displacement sockets 13 are equidistantly arranged inside the lower half of the mounting flange 7, and multiple anti-displacement rubber plugs 12 are equidistantly arranged on the top of the rubber gasket 11. The multiple anti-displacement rubber plugs 12 are respectively inserted into the anti-displacement sockets 13 corresponding to their positions. This positional relationship forms a double guarantee of precise positioning and anti-displacement. Its function is to limit the relative displacement between the rubber gasket 11 and the mounting flange 7. In principle, the physical cooperation between the plug and the socket prevents the gasket from shifting during installation, ensuring that the gasket always covers the flange sealing surface. At the same time, in long-term use, it can resist the gasket displacement caused by pipeline vibration. Compared with the traditional method of relying solely on bolts to fix the gasket, the anti-displacement effect is greatly improved. In addition, the tops of the multiple anti-displacement rubber plugs 12 are all hemispherical. The advantage of the hemispherical design is that it reduces the difficulty of aligning the plug and the socket. In principle, the hemispherical top can guide the plug to be quickly inserted into the socket through the arc surface, achieving smooth installation without precise alignment. At the same time, after insertion, the hemispherical structure can fit tightly against the inner wall of the socket through the elastic deformation of the rubber, further enhancing the anti-displacement effect.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, an annular encrypted airbag A14 is provided near the outer circular side of the rubber sealing gasket 11 and on the outer wall of its bottom end. An annular encrypted airbag B15 is provided on the inner side of the annular encrypted airbag A14, and an annular encrypted airbag C16 is provided on the inner side of the annular encrypted airbag B15. The annular encrypted airbags A14 and B15 are located on the outer and inner sides of the circular structure formed by multiple pre-drilled holes, respectively. The advantage of this nested layout is that it achieves all-round sealing without dead angles. Its function is to provide precise protection for the sealing needs of different areas. The outer annular encrypted airbag A14 can prevent fluid from seeping from the flange edge. The central annular airbag B15 fills the gaps around the pre-drilled mounting holes (where bolts easily create sealing blind spots), while the inner annular airbag C16 protects the central area of ​​the probe, forming a three-dimensional sealing system. This avoids the sealing blind spot problem present in traditional single-gasket designs. Furthermore, the cross-sectional shapes of the annular airbags A14, B15, and C16 are all semi-circular. The advantage of a semi-circular cross-section is that it maximizes the contact area between the airbag and the mounting surface. In principle, compared to circular or rectangular cross-sections, a semi-circular cross-section can more fully conform to the mounting surface under pressure, even during installation... Even with minor indentations on the surface, the airbags can fill the gaps through elastic deformation, improving sealing adaptability. Furthermore, the tops of all three airbags are sealed to the outer wall of the bottom of the rubber sealing gasket 11, ensuring that the annular encrypted airbags A14, B15, and C16 are in a sealed state. This sealing connection ensures that the gas inside the airbags does not leak. In principle, the sealed airbags can adaptively adjust the pressure after installation due to the compressibility of the internal gas, forming a stable elastic reaction force to resist fluid pressure and prevent seal failure. Additionally, the annular encrypted airbags A14 and B15... The diameters of the 5 and the annular encrypted airbag C16 increase sequentially. The advantage of increasing diameter is that it can adapt to the pressure requirements and sealing range of different areas. In principle, the larger the diameter of the airbag, the larger the volume, and the stronger the elastic reaction force when under pressure. The inner annular encrypted airbag C16 has the largest diameter, which can cope with the high fluid pressure in the center area of ​​the probe. The outer annular encrypted airbag A14 has the smallest diameter, which avoids the airbag from over-expanding due to insufficient pressure on the outside, thus affecting the installation stability. At the same time, the increasing diameter makes the airbag form a nested structure with a smaller outer diameter and a larger inner diameter, covering the sealing area without overlap or omission, maximizing the sealing efficiency.

[0030] Through the above-mentioned structural design, this utility model ensures excellent sealing and stability while primarily achieving high-precision, in-situ testing of the TPMS thermal management system performance, solving the problems of equipment miniaturization and data synchronization in this specific testing scenario.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
