Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to an integrated thermal management system and vehicle. Background Technology
[0002] The thermal management system of an electric vehicle needs to control the temperature of multiple subsystems, including the battery, electric drive, and air conditioning. Its performance directly affects the vehicle's range, charging and discharging efficiency, operational safety, and reliability. To optimize system layout and reduce costs, a highly integrated thermal management module can be used. By highly integrating electronic water pumps, valve bodies, sensors, and complex flow channels into a compact module, the system can be miniaturized, lightweighted, cost-effective, and assembly efficiency improved.
[0003] Most electronic water pumps are rigidly connected via bolts to nuts embedded in the flow channel plate of the thermal management module, which in turn is directly fixed to the vehicle body beams. As the core vibration source within the thermal management module, the electronic water pump generates wide-frequency vibrations during start-up, speed adjustment, and high-speed operation of its internal motor and rotating components. This vibrational energy is transmitted through the pump housing and then, via the rigid connection structure, to the flow channel plate and the entire thermal management module. Because the thermal management module is directly mounted to the vehicle body structure (such as longitudinal beams or the front bulkhead) using bolts and other fastening methods, the vibrational energy is further conducted to the body shell structure, causing resonance. Ultimately, this manifests as uncomfortable low-to-mid-frequency noise within the passenger compartment, severely impacting the driving and riding experience. Utility Model Content
[0004] This application provides a thermal management integrated system and vehicle that can improve the installation strength between the water pump and the flow channel plate, and can achieve the purpose of vibration reduction.
[0005] To achieve the above objectives, the main technical solutions adopted in this application include: In a first aspect, embodiments of this application provide a thermal management integrated system, which includes a flow channel plate, a water pump, and multiple fastening parts. The water pump includes a housing, and multiple mounting parts are provided on the outer peripheral surface of the housing along the circumference of the housing. The multiple fastening parts correspond one-to-one with the mounting parts. Each fastening part includes a bolt, a rubber pad, and a bushing. The rubber pad has a first hole, and a groove is provided on the outer peripheral surface of the rubber pad. At least a portion of the mounting part is embedded in the corresponding groove, and at least a portion of the bushing is disposed in the first hole. The bolt passes through the bushing and is connected to the flow channel plate.
[0006] The thermal management integrated system proposed in this application fixes the water pump to the flow channel plate by aligning the groove of the rubber pad with the mounting part, inserting the bushing into the first hole, and then inserting bolts into the bushing and connecting it. The bolts form a rigid connection with the flow channel plate via the bushing, enhancing the installation strength between the water pump and the flow channel plate. Simultaneously, because the mounting part of the water pump aligns with the groove of the rubber pad, the water pump and the flow channel plate are separated by the rubber pad, reducing direct contact between them and effectively blocking the vibration transmission path. This reduces the transmission of water pump vibration to the vehicle body, thereby improving passenger comfort.
[0007] Optionally, the mounting portion is constructed as a ring structure, and the groove is constructed as an annular groove extending circumferentially along the rubber pad.
[0008] In the above embodiment, the annular structure constructed by the mounting part is completely wrapped in the groove of the rubber pad, thereby effectively absorbing the vibration of the water pump in all directions, and thus reducing the transmission of the water pump vibration to the vehicle body.
[0009] Optionally, the mounting portion is interference-fitted into the groove.
[0010] In the above embodiment, the mounting part is interference-fitted into the groove of the rubber pad, which can better transmit the vibration energy of the water pump to the vehicle body through the rubber pad, thereby reducing the vibration of the water pump transmitted to the vehicle body.
[0011] Optionally, the bushing is provided with an internal thread that mates with the bolt.
[0012] Optionally, the bushing includes a body portion and a limiting plate. The body portion is disposed in the first hole, and the limiting plate is disposed at one axial end of the body portion, so that the limiting plate abuts against the rubber pad and the nut of the bolt.
[0013] In the above embodiment, the bolt nut transmits torque to the rubber pad through the limiting plate, improving the uniformity of force on the rubber pad and thus extending the life of the rubber pad.
[0014] Optionally, along the radial direction of the first hole, the outer diameter of the limiting plate is smaller than the outer diameter of the rubber pad.
[0015] In the above embodiment, the force generated by the vibration of the water pump is completely transmitted to the rubber pad through the bushing, thereby improving the shock absorption effect of the rubber pad.
[0016] Optionally, the rubber pad includes a first segment, a second segment, and a third segment connected in sequence. The outer diameters of the first segment and the third segment are both larger than the outer diameter of the second segment to form the groove. Along the axial direction of the first hole, the size of the first segment is equal to the size of the third segment.
[0017] In the above embodiment, the dimensions of the first segment and the third segment are the same along the axial direction of the first hole, so that the first segment and the third segment on both sides of the mounting part are symmetrically stressed and uniformly deformed, thereby allowing the vibration generated by the water pump to be uniformly absorbed by the first segment and the third segment.
[0018] Optionally, the plurality of mounting portions are evenly and spaced apart along the circumference of the housing.
[0019] In the above embodiments, the even and spaced arrangement of multiple mounting parts makes the force on the flow channel plate and the water pump housing more balanced.
[0020] Optionally, the flow channel plate is embedded with a plurality of nuts, each of which is threadedly engaged with a corresponding bolt.
[0021] Secondly, embodiments of this application provide a vehicle including the thermal management integrated system described in any of the above embodiments.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0030] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0031] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).
[0032] Currently, water pumps are generally installed using bolts and pre-embedded nuts in the flow channel plate for rigid connection. Although this structure has advantages such as reliable connection and simple assembly process, its rigidity results in minimal vibration transmission loss and almost no vibration isolation effect. Since the thermal management module is directly connected to the vehicle body, the vibration and noise generated by the electronic water pump during operation are directly transmitted to the vehicle body through the rigid structural path, and then enter the passenger compartment, affecting the ride comfort. Furthermore, it can easily cause the water pump itself or the connecting structure to fatigue damage due to stress concentration.
[0033] To reduce the impact of water pump vibration on the vehicle body, the electric water pump can be fixed to the thermal management module using a single rubber damping pad. While a single rubber pad can absorb some high-frequency vibrations, its ability to suppress low-frequency and large-amplitude vibrations is insufficient. This means that vibrations generated by the electric water pump during operation can still be easily transmitted to the thermal management module through the mounting structure, and then through the vehicle body to the passenger compartment, generating perceptible noise and resonance. Furthermore, if only a flexible connection using a rubber pad is relied upon, the rubber is prone to aging, deformation, or displacement under long-term vibration and temperature changes, leading to loose water pump installation and further exacerbating vibration transmission and abnormal noise problems.
[0034] In view of this, this application proposes a thermal management system and vehicle that has good shock absorption effect and can improve the installation stability between the water pump and the flow channel plate.
[0035] Firstly, reference Figure 1 and Figure 2 This application provides a thermal management integrated system, which includes a flow channel plate 1, a water pump 2, and multiple fastening parts 3. The water pump 2 includes a housing 21, and multiple mounting parts 22 are provided on the outer peripheral surface of the housing 21 along the circumference. The multiple fastening parts 3 correspond one-to-one with the mounting parts 22. Each fastening part 3 includes a bolt 31, a rubber pad 32, and a bushing 33. The rubber pad 32 has a first hole 321, and a groove 322 is provided on the outer peripheral surface of the rubber pad 32. At least a portion of the mounting part 22 is embedded in the corresponding groove 322, and at least a portion of the bushing 33 is provided in the first hole 321. The bolt 31 passes through the bushing 33 and is connected to the flow channel plate 1.
[0036] For example, the rubber pad 32 is made of elastic rubber material, the bushing 33 is made of stainless steel material, and the bolt 31 is made of stainless steel material.
[0037] When the housing 21 of the water pump 2 and the flow channel plate 1 are subjected to thermal expansion and contraction or external stress, the elastic rubber pad 32 can undergo small relative displacement and deformation. The mounting part 22 is embedded in the groove 322 of the rubber pad 32, and the mounting part 22 limits the rubber pad 32 radially and axially. When the bolt 31 is tightened, the tightening force is transmitted through the bushing 33 instead of directly squeezing the soft rubber, reducing the probability of the rubber pad 32 being over-compressed and failing. At the same time, the bushing 33 can improve the stability of the preload generated by the bolt 31, reducing the probability of the bolt 31 loosening due to the creep of the rubber pad 32.
[0038] The thermal management integrated system proposed in this application fixes the water pump 2 and the flow channel plate 1 by engaging the groove 322 of the rubber pad 32 with the mounting part 22, inserting part of the bushing 33 into the first hole 321, and then inserting the bolt 31 into the bushing 33 and connecting it to the flow channel plate 1. The bolt 31 forms a rigid connection with the flow channel plate 1 through the bushing 33, which improves the installation strength between the water pump 2 and the flow channel plate 1. At the same time, since the mounting part 22 of the water pump 2 is engaged in the groove 322 of the rubber pad 32, the water pump 2 and the flow channel plate 1 are separated by the rubber pad 32, which reduces the direct contact between the water pump 2 and the flow channel plate 1, effectively blocking the path of vibration transmission, thereby reducing the vibration of the water pump 2 transmitted to the vehicle body and improving the ride comfort of the passenger compartment.
[0039] Optionally, the mounting part 22 is constructed as a ring structure, and the groove 322 is constructed as an annular groove extending circumferentially along the rubber pad 32. The annular structure constructed by the mounting part 22 completely encloses the groove 322 of the rubber pad 32, which is equivalent to the rubber pad 32 completely isolating the water pump 2 from the flow channel plate 1. The rubber pad 32 evenly disperses the vibration generated by the water pump 2, thereby effectively absorbing the vibration of the water pump 2 in all directions, and thus reducing the transmission of the vibration of the water pump 2 to the vehicle body.
[0040] Optionally, the mounting part 22 is interference-fitted into the groove 322. The mounting part 22 can form a tight connection with the rubber pad 32, reducing the risk of the rubber pad 32 falling off the mounting part 22 due to gravity or movement during subsequent installation. At the same time, the interference fit of the mounting part 22 into the groove 322 of the rubber pad 32 can better transmit the vibration energy of the water pump 2 to the vehicle body through the rubber pad 32, thereby reducing the vibration of the water pump 2 transmitted to the vehicle body.
[0041] For example, along the axial direction of the first hole 321, the width of the mounting portion 22 is adapted to the width of the groove 322, and along the radial direction of the first hole 321, the thickness of the mounting portion 22 is adapted to the depth of the groove 322.
[0042] Optionally, the bushing 33 is provided with an internal thread that mates with the bolt 31. The bolt 31 is provided with an external thread, and the bushing 33 is provided with an internal thread. The external thread of the bolt 31 mates with the internal thread of the bushing 33, thereby improving the connection strength of the bolt 31 and reducing the risk of the bolt 31 loosening.
[0043] Optionally, refer to Figure 2 The bushing 33 includes a body part 331 and a limiting plate 332. The body part 331 is disposed in the first hole 321, and the limiting plate 332 is disposed at one axial end of the body part 331 so that the limiting plate 332 abuts against the rubber pad 32 and the nut of the bolt 31.
[0044] When bolt 31 is tightened, the nut presses against the limiting plate 332, which in turn presses down on the rubber pad 32. This reduces the risk of rubber pad 32 failing due to excessive torque or improper operation, thus giving the rubber pad 32 a better vibration damping effect. In other words, the nut of bolt 31 transmits torque to the rubber pad 32 through the limiting plate 332, improving the uniformity of force distribution on the rubber pad 32 and thereby extending its lifespan.
[0045] For example, the length of the body portion 331 may be equal to or less than the length of the first hole 321, depending on the specific application.
[0046] Optionally, along the radial direction of the first hole 321, the outer diameter of the limiting plate 332 is smaller than the outer diameter of the rubber pad 32. Along the axial direction of the first hole 321, the projection of the limiting plate 332 falls completely within the projection of the rubber pad 32, and the force generated by the vibration of the water pump 2 is completely transmitted to the rubber pad 32 through the bushing 33, thereby improving the shock absorption effect of the rubber pad 32.
[0047] Optionally, refer to Figure 2 The rubber pad 32 includes a first segment 323, a second segment, and a third segment 324 connected in sequence. The outer diameters of the first segment 323 and the third segment 324 are both larger than the outer diameter of the second segment, forming a groove 322. Along the axial direction of the first hole 321, the size of the first segment 323 is equal to the size of the third segment 324. The mounting part 22 is embedded in the groove 322. The first segment 323 and the third segment 324 are located on both sides of the mounting part 22. Along the axial direction of the first hole 321, the size of the first segment 323 and the third segment 324 are the same, so that the first segment 323 and the third segment 324 on both sides of the mounting part 22 are symmetrically stressed and uniformly deformed, thereby allowing the vibration generated by the water pump 2 to be uniformly absorbed by the first segment 323 and the third segment 324.
[0048] For example, the end face of the first segment 323 away from the groove 322 abuts against the flow channel plate 1 and has a toothed structure, which can play the role of anti-slip and anti-wear.
[0049] The third segment 324 has a toothed structure on the side of the end face away from the groove 322 that abuts against the limiting plate 332. This toothed structure can play a role in preventing slipping and wear.
[0050] Optionally, multiple mounting portions 22 are evenly and spaced along the circumference of the housing 21. The vibration, internal pressure, and preload of the bolts 31 during operation of the water pump 2 are transmitted to the flow channel plate 1 through the mounting portions 22. The even and spaced arrangement of the multiple mounting portions 22 ensures that these forces and torques are evenly distributed across the entire circumference of the housing 21 of the water pump 2, making the forces on the flow channel plate 1 and the housing 21 of the water pump 2 more balanced.
[0051] Optionally, the flow channel plate 1 is embedded with a plurality of nuts 11, each nut 11 being threadedly engaged with a corresponding bolt 31. The flow channel plate 1 is pre-embedded with threaded nuts 11, and the bolt 31 passes through the bushing 33 to achieve a rigid connection with the nut 11. For example, the flow channel plate 1 is embedded with four nuts 11, and the outer peripheral surface of the housing 21 is provided with four mounting portions 22, with four fastening portions 3 correspondingly mounted to the mounting portions 22 and the nuts 11.
[0052] Secondly, embodiments of this application provide a vehicle including the thermal management integrated system described in any of the above embodiments.
[0053] In this application, the rubber pad 32 serves as a shock-absorbing element, which can effectively absorb the high-frequency vibration generated by the water pump 2 and enhance the NVH performance of the whole vehicle. The mounting part 22 provided on the housing 21 of the water pump 2 corresponds to the nut 11 embedded on the flow channel plate 1. The bolt 31 forms a hard connection with the pre-embedded nut 11 through the bushing 33, which ensures the rigidity and positional accuracy of the connection between the water pump 2 and the flow channel plate 1 and reduces the loosening of the installation caused by rubber aging or deformation.
[0054] In other words, the fastening part 3 in this application can improve the installation strength of the water pump 2 and the flow channel plate 1, while the rubber pad 32 can isolate the direct contact between the water pump 2 and the flow channel plate 1, effectively blocking the vibration transmission path and achieving the purpose of vibration reduction.
[0055] In addition, the rubber pad 32 and bushing 33 are standard parts, which are easy to replace and maintain, reducing the cost of later maintenance.
[0056] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0057] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
