Description

Technical Field

[0001] This invention relates to the field of thermal management technology for new energy vehicles, specifically a thermal management system assembly with replaceable filter inserts. Background Technology

[0002] The operational stability and lifespan of power batteries for new energy vehicles are highly sensitive to operating temperature. Liquid cooling thermal management systems are the mainstream solution for regulating battery operating temperature. Coolant circulates in a closed pipeline to achieve heat exchange. To prevent impurities in the coolant from clogging the heat exchange channels and reducing heat exchange efficiency, a filter device needs to be connected in series in the circulation pipeline to purify the coolant. Such filter devices are widely used in the battery thermal management circuits of various new energy vehicles.

[0003] Existing thermal management pipeline filtration devices typically employ a fixed-assembly sealing structure. They rely on a preset assembly clamping force to fill the gap between the filter element and the housing with the seal, thereby achieving a static sealing effect. The clamping degree of this type of sealing structure is a fixed value, and it cannot dynamically adjust the sealing clamping force according to changes in the water pressure inside the pipeline. When the water pressure inside the pipeline increases, the fluid pressure can easily force open the sealing mating surface, creating a gap and causing coolant leakage. At the same time, high-pressure impacts can also reduce the installation stability of the filter element. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal management system assembly with replaceable filter inserts, aiming to improve the problem in the prior art that the sealing structure cannot dynamically adjust the sealing pressure according to changes in the water pressure inside the pipeline.

[0005] The objective of this invention is achieved through the following technical solution: a thermal management system assembly with replaceable filter inserts, including an automotive battery module, wherein a protective shell is fitted on the outer side of the automotive battery module, a heat exchange pipeline is coiled around the outer wall of the protective shell, heat dissipation fins are arranged and connected on the outer surface of the heat exchange pipeline, and a filter mechanism is connected in series at the end of the heat exchange pipeline. The filtration mechanism includes a filter box, inside which several sets of filter inserts are slidably inserted along the water flow direction. A locking mechanism is provided on the inner side wall of the filter box corresponding to the position of each set of filter inserts. An elastic sealing sleeve is provided between the inner wall of the filter box and the insertion end of the filter inserts. The locking mechanism includes an outer ring, a drive rod, a flow guide bucket, and a locking insert. The outer ring is rotatably sleeved on the outer periphery of the flow guide bucket. The drive rod is radially connected through the side wall of the outer ring. A flow-facing groove is opened on the water-facing end face of the flow guide bucket, and the opening of the flow-facing groove is set in the direction of water flow. A locking insert is fixedly connected to the end face of the flow guide bucket facing the filter insert.

[0006] As a further description of the above technical solution: The filter insert includes a wedge-shaped insert, with a docking slot on the side of the wedge-shaped insert facing the flow hopper. The locking insert has a strip-shaped protrusion structure. The cavity shape of the docking slot is adapted to the shape of the locking insert. A hollow sealing ring is provided inside the wedge-shaped insert on the inner side of the docking slot. The outer circle shape of the hollow sealing ring is adapted to the end face shape of the locking insert. A membrane collar is fitted inside the hollow sealing ring. A filter membrane is fixedly connected to the inner ring surface of the membrane collar. As a further description of the above technical solution: The locking mechanism also includes a movable groove, an elastic shaft, and a wedge-shaped pressure block. The movable groove is provided inside the side wall of the outer ring, and an elastic shaft is provided inside the movable groove. The end of the elastic shaft is connected to a wedge-shaped pressure block, and the wedge-shaped surface of the wedge-shaped pressure block abuts against the wedge-shaped surface of the end of the drive rod. As a further description of the above technical solution: The top of the wedge-shaped insert is fixedly connected to a handle. Magnetic rings are provided on both sides of the wedge-shaped insert and the inner end face of the filter box. Magnetic rings are also provided on the corresponding end face of the elastic sealing sleeve. The two sets of magnetic rings attract and cooperate with each other to complete the sealing treatment of the entire water circuit. As a further description of the above technical solution: The hollow sealing ring has a cross-section in the form of an annular structure with a concave cavity, and the two bottom corners of the inner side of the hollow sealing ring are respectively attached to the two end faces of the diaphragm collar. As a further description of the above technical solution: The filter box contains multiple sets of filter inserts arranged sequentially along the water flow direction. Each set of filter inserts is equipped with a locking mechanism and a set of elastic sealing sleeves. As a further description of the above technical solution: The wedge-shaped pressure block is slidably embedded inside the movable groove, one end of the elastic shaft is fixedly connected to the inner wall of the movable groove, and the other end of the elastic shaft is fixedly connected to the back end face of the wedge-shaped pressure block. As a further description of the above technical solution: The heat exchange pipeline is coiled around the outer wall of the protective shell in a reciprocating bend, and the heat dissipation fins are arranged at intervals along the extension direction of the heat exchange pipeline, and the inner side of the heat dissipation fins is fixedly connected to the outer wall of the heat exchange pipeline.

[0007] Compared with the prior art, the advantages of the present invention are as follows: 1. Water flow acts on the inlet groove of the inlet bucket, causing the inlet bucket to move axially towards the filter insert. The inlet bucket then drives the locking insert to extend further into the wedge-shaped insert's slot. The end face of the locking insert presses against the hollow sealing ring inside the slot. Under axial pressure, the hollow sealing ring's internal cavity contracts, causing the two bottom corners of the inner side of the hollow sealing ring to expand and press against the two end faces of the membrane collar. The higher the water pressure, the greater the pressing stroke and the greater the clamping force. This achieves a water pressure-adaptive sealing effect, allowing the sealing structure to dynamically adjust the sealing tightness according to the internal pressure of the pipeline. The higher the pressure, the tighter the seal, effectively avoiding the risk of leakage under high-pressure conditions, while also enhancing the installation stability of the filter membrane.

[0008] 2. The magnetic ring on the side of the wedge-shaped insert and the magnetic ring on the end face of the elastic sealing sleeve attract each other, causing the filter insert to quickly align with the insertion reference position and complete the pre-positioning. The drive rod moves linearly along the axial direction, causing the outer ring and the drainage bucket to move forward synchronously, allowing the locking insert to embed into the docking slot and complete the initial axial locking. Rotating the drive rod squeezes the wedge-shaped pressure block through the wedge surface and compresses the elastic shaft, relying on the elastic force of the elastic shaft to complete the circumferential locking. Reversing the rotation and pulling the drive rod will cause the locking insert to disengage from the docking slot and release the lock. This achieves the beneficial effect of rapid filter insert installation and removal, allowing for filter screen installation, locking, unlocking, and disassembly without the need for additional tools, reducing maintenance difficulty and effectively improving the convenience of system operation and maintenance.

Detailed Implementation

[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 9 The diagram shows an embodiment of a thermal management system assembly with replaceable filter inserts provided by the present invention. The assembly includes an automotive battery module 1, which serves as the core of the thermal management system for temperature control, providing electrical energy output to the vehicle. A protective shell 2 is fitted around the outer side of the automotive battery module 1, providing structural protection and a mounting base for the heat exchange pipes 3. The heat exchange pipes 3 are coiled around the outer wall of the protective shell 2, allowing coolant to circulate and conduct heat through the pipe walls to regulate the battery's operating temperature. Heat dissipation fins 4 are arranged and connected to the outer surface of the heat exchange pipes 3, increasing the heat exchange surface area, accelerating heat dissipation, and improving overall heat dissipation efficiency. A filter mechanism 5 is connected in series at the end of the heat exchange pipes 3, within the thermal management circuit, to filter and purify the circulating coolant, preventing blockage of the heat exchange channels. The heat exchange pipe 3 is coiled around the outer wall of the protective shell 2 in a reciprocating bend, which can extend the heat exchange path of the coolant and increase the heat exchange coverage area per unit space. The heat dissipation fins 4 are arranged at intervals along the extension direction of the heat exchange pipe 3, and the inner side of the heat dissipation fins 4 is fixedly connected to the outer wall of the heat exchange pipe 3, which can ensure uniform heat conduction and enhance the overall heat dissipation effect.

[0012] The filtration mechanism 5 includes a filter box 51, which serves as the external supporting housing for the filtration mechanism 5, providing installation space and insertion channels for internal components and forming a flow cavity for the coolant. Several sets of filter inserts 53 are slidably inserted into the filter box 51 along the water flow direction. These filter inserts 53 serve as modular filtration units, supporting the core filtration components and can be independently removed and replaced for convenient maintenance. A locking mechanism 52 is provided on the inner wall of the filter box 51 corresponding to the position of each set of filter inserts 53. The locking mechanism 52 achieves axial locking and circumferential limiting of the filter inserts 53, ensuring installation stability under water pressure conditions. An elastic sealing sleeve 54 is provided between the inner wall of the filter box 51 and the insertion end of the filter insert 53. The elastic sealing sleeve 54 fills the insertion gap, achieving a basic static seal at the insertion point and preventing coolant leakage. Multiple sets of filter inserts 53 are arranged sequentially inside the filter box 51 along the water flow direction, enabling staged filtration and improving impurity interception accuracy and filtration effect. Each filter insert 53 is equipped with a locking mechanism 52 and an elastic sealing sleeve 54 to ensure that each filter unit has independent locking and sealing capabilities.

[0013] The locking mechanism 52 includes an outer ring 521, a drive rod 522, a diversion bucket 523, and a locking insert 525. The outer ring 521 serves as the mounting carrier for the locking component and can transmit axial driving force to drive the diversion bucket 523 to move synchronously. The drive rod 522 allows the operator to apply operating force. The locking insert 525 is inserted and separated through axial movement, and the locking limit is completed through circumferential rotation. The diversion bucket 523 is located on the upstream side of the water flow, guiding the coolant to flow evenly to the filter membrane 537. At the same time, it receives the water flow pressure and converts it into axial displacement driving force. The locking insert 525 can be inserted into the docking slot 534 to realize the axial insertion and positioning of the filter insert 53, while transmitting axial pressure to squeeze the sealing component. An outer ring 521 is rotatably fitted around the outer periphery of the diversion bucket 523. A drive rod 522 is radially connected through the side wall of the outer ring 521. A flow-receiving groove 524 is formed on the water-facing end face of the diversion bucket 523. The flow-receiving groove 524 increases the contact area between the diversion bucket 523 and the water flow, fully bearing the water pressure and enhancing the displacement effect driven by water pressure. The opening of the flow-receiving groove 524 is oriented towards the water inflow direction. A locking insert 525 is fixedly connected to the end face of the diversion bucket 523 facing the filter insert 53.

[0014] The locking mechanism 52 also includes a movable groove 526, an elastic shaft 527, and a wedge-shaped pressure block 528. The movable groove 526 provides a space for the wedge-shaped pressure block 528 and the elastic shaft 527 to slide and guide, limiting the travel of the wedge-shaped pressure block 528. The elastic shaft 527 provides a restoring force by its own elastic deformation, pushing the wedge-shaped pressure block 528 to continuously press against the drive rod 522, maintaining the clamping force in the locked state. The wedge-shaped pressure block 528, through the wedge-shaped surface cooperating with the wedge-shaped surface of the drive rod 522, converts the circumferential rotation into axial compressive force, realizing the circumferential locking limit of the drive rod 522. The inner sidewall of the outer ring 521 has a movable groove 526. The movable groove 526 is equipped with an elastic shaft 527. The end of the elastic shaft 527 is connected to a wedge-shaped pressure block 528. The wedge-shaped surface of the wedge-shaped pressure block 528 abuts against the end wedge-shaped surface of the drive rod 522. The wedge-shaped pressure block 528 is slidably embedded in the interior of the movable groove 526. One end of the elastic shaft 527 is fixedly connected to the inner wall of the movable groove 526, and the other end of the elastic shaft 527 is fixedly connected to the back end face of the wedge-shaped pressure block 528.

[0015] The filter insert 53 includes a wedge-shaped insert 531, which serves as the main supporting frame for the filter insert 53, providing an installation base for each internal component and adapting to the insertion slot structure of the filter box 51. A docking slot 534 is provided on the side of the wedge-shaped insert 531 facing the flow guide 523. The docking slot 534 is adapted to the shape of the locking insert 525, allowing the locking insert 525 to be inserted and positioned axially. The locking insert 525 has a strip-shaped protrusion structure, and the cavity shape of the docking slot 534 is adapted to the shape of the locking insert 525. A hollow sealing ring 535 is provided inside the wedge-shaped insert 531, located inside the docking slot 534. When subjected to axial pressure, the internal cavity of the hollow sealing ring 535 contracts and its sides expand, dynamically pressing the diaphragm collar 536 to achieve a water pressure-adaptive sealing enhancement effect. Furthermore, the outer circular shape of the hollow sealing ring 535 matches the end face shape of the locking insert 525, ensuring uniform and sufficient pressure transmission. A diaphragm collar 536 is fitted inside the hollow sealing ring 535, providing fixed support for the filter membrane 537, transmitting radial clamping force, and ensuring the flatness and sealing performance of the filter membrane 537. The cross-section of the hollow sealing ring 535 is an annular structure with a concave cavity, ensuring sufficient deformation space under pressure. The two bottom corners of the inner side of the hollow sealing ring 535 are respectively fitted to the two end faces of the diaphragm collar 536, which can convert axial pressure into radial clamping force, enhancing the sealing effect. The filter membrane 537 is fixedly connected to the inner ring surface of the diaphragm collar 536. The filter membrane 537 intercepts solid impurities in the coolant, achieving coolant purification and filtration, and maintaining the cleanliness of the thermal management circuit.

[0016] A handle 532 is fixedly connected to the top of the wedge-shaped insert 531, providing the operator with a gripping and force-applying part to facilitate the insertion and removal of the filter insert 53. Magnetic rings 533 are provided on both sides of the wedge-shaped insert 531 and the inner end face of the filter box 51. Magnetic rings 533 are also provided on the corresponding end face of the elastic sealing sleeve 54. The magnetic rings 533 achieve rapid pre-positioning of the filter insert 53 through magnetic attraction, helping to improve the insertion and alignment accuracy. The two sets of magnetic rings 533 attract and cooperate with each other to complete the sealing treatment of the entire water circuit, helping to strengthen the sealing fit of the insertion part.

[0017] Working principle: The operator holds the handle 532 on the top of the wedge-shaped insert 531, aligns the wedge-shaped insert 531 with the corresponding slot on the top of the filter box 51, and inserts the wedge-shaped insert 531 downward along the slot direction. During the insertion process, the magnetic ring 533 on the side of the wedge-shaped insert 531 and the magnetic ring 533 on the end face of the elastic sealing sleeve 54 approach each other and generate an adsorption effect, which drives the wedge-shaped insert 531 to the insertion reference position, so that the elastic sealing sleeve 54 is placed between the inner wall of the filter box 51 and the insertion end of the wedge-shaped insert 531, completing the initial docking and positioning of the filter insert 53.

[0018] The drive rod 522 is pushed along the axial direction, causing it to move linearly towards the filter insert 53 along its own axis. During the movement of the drive rod 522, the outer ring 521 is synchronously displaced axially. The outer ring 521 slides forward along the outer circumference of the diversion bucket 523. The axial force of the outer ring 521 is transmitted to the diversion bucket 523, causing the diversion bucket 523 to move synchronously towards the filter insert 53 along the axial direction. The locking insert 525 on the end face of the diversion bucket 523 moves synchronously with the diversion bucket 523 and gradually inserts into the docking slot 534 opened on the side of the wedge-shaped insert 531 until the drive rod 522 moves to the end position of the linear stroke. The locking insert 525 is completely embedded in the cavity of the docking slot 534, completing the initial axial locking of the filter insert 53.

[0019] As the drive rod 522 rotates around its central axis, the wedge-shaped surface at its end rotates circumferentially in sync with the rotation. This causes relative sliding and a squeezing action between the wedge-shaped surface of the drive rod 522 and the wedge-shaped pressure block 528. Under this squeezing force, the wedge-shaped pressure block 528 retracts into the movable groove 526. During this retraction, the wedge-shaped pressure block 528 compresses the elastic shaft 527 inside the movable groove 526, causing axial compression deformation of the elastic shaft 527. After the elastic shaft 527 is compressed, it generates a reverse elastic force, which pushes the wedge-shaped pressure block 528 to reset and press against the drive rod 522, so that the wedge-shaped surface of the wedge-shaped pressure block 528 and the wedge-shaped surface of the drive rod 522 are in close contact, thus limiting the circumferential rotation stroke of the drive rod 522. During this process, the outer ring 521 rotates synchronously with the drive rod 522 around the outer circumference of the diversion bucket 523, and the diversion bucket 523 and the locking insert 525 remain stationary and do not undergo circumferential deflection.

[0020] Coolant enters the filter box 51 from the inlet and flows sequentially through multiple sets of filter inserts 53 along the water flow direction. The water first contacts the flow-facing groove 524 on the water-facing end face of the guide bucket 523, then passes through the hollow flow area of ​​the guide bucket 523, and reaches the filter membrane 537 of the first set of filter inserts 53. After the first layer of filter membrane 537 completes the primary impurity interception, the water continues to flow to the next set of filter inserts 53, and sequentially passes through multiple layers of filter membrane 537 to complete the staged filtration process. After filtration, the coolant flows out of the filter box 51 and enters the series-connected heat exchange pipeline 3. The coolant flows continuously in the heat exchange pipeline 3, which is arranged in a reciprocating bend. During the flow, heat is transferred to the pipe wall of the heat exchange pipeline 3, and the heat is then conducted outward through the heat dissipation fins 4 arranged at intervals on the outer surface of the heat exchange pipeline 3. The coolant circulates in the circuit and completes continuous heat exchange with the car battery module 1 inside the protective shell 2.

[0021] When the water pressure inside the pipeline increases, the pressure of the water flow acting on the end face of the flow-receiving groove 524 increases synchronously. The pressure pushes the flow-guiding bucket 523 to continue to move axially towards the filter insert 53. The flow-guiding bucket 523 drives the locking insert 525 to extend further into the docking slot 534. The end face of the locking insert 525 presses against the hollow sealing ring 535 set inside the docking slot 534. After the hollow sealing ring 535 is subjected to axial pressure, the volume of the internal cavity of the hollow sealing ring 535 shrinks. The two corners of the bottom inside the hollow sealing ring 535 are compressed and expand and squeeze against the two end faces of the membrane collar 536, forming a radial pressing force on the membrane collar 536. Simultaneously, it drives the filter membrane 537 inside the membrane collar 536 to fit more tightly.

[0022] During the filtration process, the solid waste intercepted by each layer of filter membrane 537 settles downwards under its own gravity. The waste falls along the gap between adjacent locking inserts 525 and accumulates in the area of ​​the diversion bucket 523 on the side opposite to the direction of water flow, and does not enter the downstream filtration stage with the main fluid.

[0023] When the filter insert 53 needs to be replaced or cleaned, rotate the drive rod 522 in the reverse direction to disengage the wedge-shaped surface of the drive rod 522 from the wedge-shaped surface of the wedge-shaped pressure block 528, thereby releasing the circumferential limit on the drive rod 522. Then, pull the drive rod 522 in the reverse direction along the axial direction. The drive rod 522 drives the outer ring 521 and the diversion bucket 523 to move synchronously away from the filter insert 53. The locking insert 525 moves outward synchronously with the diversion bucket 523 and is completely pulled out from the inside of the docking slot 534, releasing the axial lock on the wedge-shaped insert 531. After that, the operator holds the handle 532 and pulls it upward to remove the wedge-shaped insert 531, together with the internal membrane collar 536 and filter membrane 537, from the slot of the filter box 51. Use the flushing water flow to flush and clean the waste residue accumulated on the surface of the filter membrane 537, around the hollow sealing ring 535, and inside the elastic sealing sleeve 54. After cleaning, it can be reinstalled in the filter box 51 for recycling.
