Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to an integrated thermal management unit for vehicles and a vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, the demand for in-vehicle thermal management systems is increasing, and the number of components required for these systems is also rising. Currently, the components of vehicle air conditioning and thermal management systems are distributed across various parts of the front compartment, requiring complex piping connections between them. This results in complex assembly methods and occupies a significant amount of front compartment space. Furthermore, given the limited space in the vehicle, if the components of the air conditioning and thermal management systems occupy a large area of ​​the front compartment, it will reduce the space inside the passenger compartment, thereby affecting the overall ride comfort. Summary of the Invention

[0003] This application provides an integrated thermal management unit and vehicle for vehicles, which can reduce the space occupied in the front compartment and improve assembly efficiency.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] In a first aspect, embodiments of this application provide a thermal management integrated unit for a vehicle, including a front-end module and an air conditioning unit. The front-end module includes a fan and a fan cover. Along a first direction, the fan cover includes a first wall and a second wall disposed opposite to each other. The air conditioning unit is disposed on the first wall and extends toward the rear of the vehicle. The first direction is perpendicular to the air outlet direction of the fan.

[0006] The integrated thermal management unit proposed in this application combines the front-end module and the air conditioning unit, reducing the need for separate mounting brackets or beams for each module. This reduces the vehicle's weight and the space occupied in the front compartment, freeing up more space for the passenger cabin. Since both the front-end module and the air conditioning unit contain vibration sources, integrating them reduces the transmission of vibrations to the vehicle body, improving NVH performance and passenger cabin comfort.

[0007] Furthermore, by integrating the front-end module and the air conditioning unit into one piece, the integrated unit can be installed together on the vehicle body, thereby improving installation efficiency.

[0008] Optionally, the integrated thermal management unit also includes a compressor and a compressor bracket, wherein the compressor bracket is integrally formed with the second wall, and the compressor is disposed on the compressor bracket.

[0009] In the above embodiments, the compressor bracket and the second wall are integrally formed, which can reduce the number of connecting parts between the compressor bracket and the second wall, thereby achieving the purpose of weight reduction and cost reduction, and can also improve the integration of the thermal management integrated machine and reduce the space occupied by the thermal management integrated machine.

[0010] Optionally, along the air outlet direction of the fan, the fan cover includes a third wall and a fourth wall disposed opposite to each other; the integrated thermal management unit also includes a refrigerant-side flow channel plate, which is disposed on the third wall and has a refrigerant flow channel inside the refrigerant-side flow channel plate.

[0011] In the above embodiments, the agent-side flow channel plate is connected to the fan shroud, reducing the brackets connected to the agent-side flow channel plate and the crossbeams connecting the brackets to the vehicle body, thereby reducing the weight of the integrated thermal management unit and eliminating the space occupied by the agent-side flow channel plate.

[0012] Optionally, the thermal management unit also includes a water-side flow channel plate, which is disposed on the third wall and has coolant flow channels inside.

[0013] In the above embodiments, the coolant flow channel is integrated into the fan shroud via a water-side flow channel plate, which reduces the space occupied by the coolant flow channel and simplifies the piping setup of the coolant flow channel.

[0014] Optionally, along the air outlet direction of the fan, the projection of the water-side flow channel plate does not overlap with the projection of the agent-side flow channel plate.

[0015] In the above embodiments, the agent-side flow channel plate and the water-side flow channel plate are laid flat on the third wall, thereby reducing the space occupied by the thermal management unit along the air outlet direction of the fan.

[0016] Optionally, the thermal management unit also includes a condenser, which is located on the side of the fourth wall away from the third wall and connected to the agent-side flow channel plate or the fourth wall.

[0017] In the above embodiment, the condenser is located on one side of the fan outlet direction so that the fan guides the airflow to act on the condenser, promoting heat dissipation and improving heat dissipation efficiency. At the same time, installing the condenser on one side of the fan shroud reduces the space occupied by the entire thermal management integrated module.

[0018] Optionally, the condenser has a first interface, and the refrigerant-side flow channel plate has a second interface communicating with the refrigerant flow channel, wherein the first interface and the second interface are connected.

[0019] In the above embodiments, the agent-side flow channel plate is connected to the first interface of the condenser through the second interface, thereby saving the pipeline connection between the agent-side flow channel plate and the condenser, thus reducing the space occupied by the integrated thermal management unit.

[0020] Optionally, the condenser includes multiple refrigerant pipes and fins. The multiple refrigerant pipes are all connected to the first interface. The fins are disposed between two adjacent refrigerant pipes. The fins include multiple first fins and multiple second fins. Along the air outlet direction of the fan, the projections of the multiple first fins overlap with the projection of the fan, while the projections of the multiple second fins do not overlap with the projection of the fan. The maximum spacing between two adjacent first fins is less than the maximum spacing between two adjacent second fins.

[0021] In the above embodiments, the multiple first fins are arranged relatively densely, so that the airflow in the area directly in front of the fan can be fully utilized, thereby improving the heat dissipation efficiency.

[0022] Optionally, the integrated thermal management unit also includes a thermal management controller, which is located on the third wall.

[0023] In the above embodiments, the thermal management controller is integrated with the front-end module, which can reduce the connection length of pipelines and wiring harnesses between the front-end module and the thermal management controller, thereby improving the control accuracy of the thermal management controller and reducing the energy loss of the thermal management system.

[0024] Secondly, embodiments of this application provide a vehicle that includes the integrated thermal management unit described in any of the above embodiments. The vehicle in this application, including the integrated thermal management unit described in any of the above embodiments, has the beneficial effects described in any of the above embodiments.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0040] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0041] 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.

[0042] 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.

[0043] 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 three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0044] 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).

[0045] Currently, the components of the thermal management system are arranged in a separate, modular manner, which occupies a large amount of front compartment space. Furthermore, the components require refrigerant pipes for connection, which is inconvenient for the installation of other components in the vehicle. This reduces the utilization rate of the vehicle's installation space, resulting in higher vehicle production costs and an increased probability of leakage.

[0046] The thermal management system design tends to optimize individual components without fully considering integrated layout. This results in multiple components, such as water pumps, water valves, and expansion valves, being scattered in different locations in the forward compartment, creating a complex piping layout that occupies a significant amount of space. This dispersed component and complex piping layout not only increases the difficulty of initial assembly but also leads to high system flow resistance due to the complex piping layout and multiple connection points, resulting in severe heat loss.

[0047] To address these issues, the industry has been exploring new integrated thermal management technologies. However, while current integrated module technologies have achieved some degree of component integration, most adopt a decentralized approach, with multiple valves controlled through this decentralized configuration. This results in complex wiring harnesses and piping connections, leading to current thermal management systems that still occupy a large space and have complex piping layouts, such as separate assembly lines for compressors and piping. This requires more complex assembly methods, which not only increases the material costs of components such as management systems but also limits the overall vehicle production efficiency.

[0048] In addition, in the thermal management system, the compressor, the front-end cooling module and the air conditioning unit are all vibration sources. These three are fixed to the vehicle body, meaning that the vibrations of three vibration sources are directly transmitted to the vehicle body, which increases the complexity of the vehicle's NVH (Noise, Vibration and Harshness) and is detrimental to the comfort of passengers in the passenger compartment.

[0049] Therefore, in order to reduce the space occupied by the thermal management system in the front compartment, increase the space in the passenger compartment, and improve passenger comfort, it is necessary to further improve the integration of the thermal management system. At the same time, to reduce the impact of vibration sources such as the compressor, front-end cooling module, and air conditioning unit on the vehicle body, it is necessary to reduce the direct contact between these vibration sources and the vehicle body, thereby reducing the impact of vibration on the vehicle body and improving passenger comfort.

[0050] In view of this, this application provides an integrated thermal management unit for vehicles, which can reduce the space occupied in the front compartment and improve the assembly efficiency of the whole vehicle.

[0051] Firstly, reference Figures 1 to 3 This application provides a thermal management unit for a vehicle. The thermal management unit includes a front-end module 1 and an air conditioning unit 2. The front-end module 1 includes a fan 11 and a fan cover 12. Along the first direction X, the fan cover 12 includes a first wall 121 and a second wall 122 that are disposed opposite to each other. The air conditioning unit 2 is disposed on the first wall 121 and extends toward the rear of the vehicle. The first direction X is perpendicular to the air outlet direction Y of the fan 11.

[0052] The fan 11 is rotatably mounted on the fan cover 12. For example, the fan cover 12 may have a receiving cavity, in which the fan 11 is located, and the fan 11 is rotatably mounted on one side wall of the fan cover 12. The other side of the fan cover 12 opposite to the side wall where the fan 11 is mounted has an opening for the fan 11 to exhaust air. Of course, the fan cover 12 may also have other possible structures, as long as it can provide a mounting position for the fan 11, and along the air exhaust direction Y of the fan cover 12, one side of the fan cover 12 can receive air and the other side can exhaust air. The specific structural form of the fan cover 12 is not limited in this application.

[0053] In this application, the air outlet direction Y of the fan cover 12 can be the front-to-back direction of the vehicle, and the first direction X can be a left-right direction perpendicular to the air outlet direction Y of the fan cover 12, or it can be a top-to-bottom direction. The air conditioning unit 2 is disposed on the first wall 121 of the fan cover 12. The air conditioning unit 2 can be disposed on one side of the fan cover 12 in the top-to-bottom direction, or on one side of the fan cover 12 in the left-to-right direction. For example, to reduce the space occupied by the air conditioning unit 2 in the left-to-right direction of the vehicle, it can be disposed on one side wall of the fan cover 12 in the top-to-bottom direction; or to reduce the space occupied by the air conditioning unit 2 in the top-to-bottom direction of the vehicle, it can be disposed on one side wall of the fan cover 12 in the left-to-right direction. The specific installation position of the air conditioning unit 2 can be determined according to specific circumstances.

[0054] The air conditioning unit 2 extends towards the rear of the vehicle so that the structure of the front module 1 can be closer to the front of the vehicle, thereby enabling the front module 1 to have a larger area of ​​contact with the airflow entering the front compartment more quickly, which is beneficial to the heat dissipation of the front module 1.

[0055] The integrated thermal management unit proposed in this application integrates the front-end module 1 and the air conditioning unit 2 together. This reduces the need for separate mounting brackets or beams for the front-end module 1 and the air conditioning unit 2, thereby reducing the vehicle's weight and minimizing the space occupied in the front compartment. This frees up more space in the front compartment for increasing the passenger compartment's interior space. Since both the front-end module 1 and the air conditioning unit 2 contain vibration sources, integrating these two sources reduces the transmission of vibrations to the vehicle body, thus improving the vehicle's NVH performance and enhancing passenger comfort.

[0056] Furthermore, by integrating the front-end module 1 and the air conditioning unit 2 into one unit, the integrated whole can be installed on the vehicle body, thereby improving installation efficiency.

[0057] In addition, since the current air conditioning unit 2 is located below the instrument panel, it results in a large volume of the instrument panel and a large space occupation. In this application, the air conditioning unit 2 is integrated into the front module 1 of the front cabin. Only three air ducts connected to the air conditioning unit 2 for blowing the face, blowing the feet and defrosting need to be extended into the passenger compartment, thereby reducing the space occupied by the instrument panel assembly, as well as the weight and cost of the instrument panel assembly, and thus increasing the space in the passenger compartment.

[0058] The air conditioning unit 2 in this application can accommodate components such as an evaporator, a blower, and a damper. For example, the evaporator is used for the expansion and evaporation of high-temperature and high-pressure liquid refrigerant, absorbing the heat of the air flowing over its surface, thereby cooling and dehumidifying the air; the damper changes the airflow path by rotating or translating, thereby changing the air outlet mode such as blowing on the face, blowing on the feet, defrosting, etc. The damper is usually driven by a motor (stepper motor or servo motor); the blower is used to provide the power for airflow, drawing air into the air conditioning unit 2 and pushing the airflow through the various components.

[0059] In one specific embodiment, the evaporator and condenser 6 in the air conditioning unit 2 have refrigerant flow channels, and the front-end module 1 also has a refrigerant flow channel. The refrigerant flow channel of the front-end module 1 is connected to the refrigerant flow channel in the air conditioning unit 2. Since the air conditioning unit 2 and the front-end module 1 are integrated together, the piping between the air conditioning unit 2 and the front-end module 1 can be reduced, thereby reducing the space occupied by the integrated thermal management unit and thus freeing up more front cabin space.

[0060] In one specific embodiment, along the air outlet direction Y of the fan 11, the projection of the air conditioning unit 2 does not overlap with the projection of the fan 11, thereby reducing the impact of the air conditioning unit 2 on the air intake or exhaust of the fan 11.

[0061] Optionally, refer to Figure 1 The integrated thermal management unit also includes a compressor 31 and a compressor bracket 32. The compressor bracket 32 ​​is integrally formed with the second wall 122, and the compressor 31 is located on the compressor bracket 32.

[0062] The compressor bracket 32 ​​and the second wall 122 are integrally formed, which reduces the number of connecting parts between the compressor bracket 32 ​​and the second wall 122, thereby achieving the purpose of weight reduction and cost reduction, and can also improve the integration of the thermal management unit and reduce the space occupied by the thermal management unit. At the same time, since the compressor 31 is a vibration source, if the compressor bracket 32 ​​is directly connected to the vehicle body during the vibration of the compressor 31, the vibration of the compressor 31 will be transmitted to the vehicle body through the connection point between the compressor bracket 32 ​​and the vehicle body, which will reduce the NVH performance of the vehicle body. Furthermore, if the compressor bracket 32 ​​is connected to the vehicle body or other structures through bolts or other structures, stress concentration will occur at the connection point during the vibration of the compressor 31, resulting in insufficient rigidity and fatigue damage, which will affect the long-term reliability of the compressor 31. In this application, the compressor bracket 32 ​​and the second wall 122 are integrally designed, reducing the number of connection points, thereby improving the rigidity and vibration reliability of the thermal management unit, and reducing the direct transmission of the vibration of the compressor 31 to the vehicle body.

[0063] The compressor bracket 32 ​​can be located at any position on the fan cover 12. For example, the compressor bracket 32 ​​can be located on any side of the fan cover 12 along the air outlet direction Y of the fan 11, or on any side of the first direction X, or on any side of the air outlet direction Y of the fan 11, etc. It can be determined according to the specific situation, as long as the compressor 31 can be installed on the fan cover 12 to reduce the space occupied by the thermal management unit.

[0064] In one embodiment, the compressor 31 is flexibly connected to the compressor bracket 32 ​​via shock-absorbing pads and bolts, thereby further reducing the energy of compressor 31 vibration transmitted to the vehicle body and improving passenger comfort in the passenger compartment. Furthermore, the integrated thermal management unit can be installed as a single unit on the vehicle assembly line, improving the installation efficiency of the assembly line.

[0065] For example, the connection between the thermal management unit and the vehicle body can also be made through a shock-absorbing pad, further reducing the impact of the thermal management unit's vibration on the vehicle body.

[0066] Optionally, refer to Figure 1 and Figure 3 Along the air outlet direction Y of the fan 11, the fan cover 12 includes a third wall 123 and a fourth wall 124 arranged opposite to each other; the thermal management integrated unit also includes a refrigerant side flow channel plate 4, which is located on the third wall 123 and has a refrigerant flow channel inside.

[0067] The agent-side flow channel plate 4 is connected to the fan cover 12 by studs, bolts, etc. Compared with the existing design, the bracket connected to the agent-side flow channel plate 4 and the crossbeam connecting the bracket to the vehicle body are reduced, thereby reducing the weight of the thermal management unit and reducing the space occupied by the agent-side flow channel plate 4.

[0068] In one embodiment, the projection of the refrigerant-side flow channel plate 4 does not overlap with the projection of the fan 11 along the air outlet direction Y of the fan 11. The refrigerant-side flow channel plate 4 is provided with refrigerant channels, which are used to contain refrigerant. Integrating the refrigerant channels into the fan shroud 12 via the refrigerant-side flow channel plate 4 reduces the space occupied by the refrigerant channels and simplifies the piping arrangement. The fact that the projection of the refrigerant-side flow channel plate 4 does not overlap with the projection of the fan 11 along the air outlet direction Y of the fan 11 indicates that the refrigerant-side flow channel plate 4 does not obstruct the fan 11, nor does it affect the fan 11's air intake, exhaust, and heat dissipation, thereby improving heat dissipation efficiency.

[0069] The refrigerant-side flow channel plate 4 has multiple mounting positions for installing refrigerant valves and / or sensors. Components such as refrigerant valves and sensors can be directly fixed to the refrigerant-side flow channel plate 4 and connected to the refrigerant flow channel through an interface, thereby reducing the connecting pipes between refrigerant valves and other components and the refrigerant flow channel, and thus reducing the space occupied by the integrated thermal management unit.

[0070] The refrigerant-side flow channel plate 4 is also provided with a first heat exchanger 42, which is connected to the refrigerant flow channel in the refrigerant-side flow channel plate 4. The first heat exchanger 42 is used for heat exchange of the refrigerant. To install the first heat exchanger 42 on the refrigerant-side flow channel plate 4, it is only necessary to connect the first heat exchanger 42 to the interface on the refrigerant-side flow channel plate 4 that is connected to the refrigerant flow channel. This can reduce the number of pipes connecting the first heat exchanger 42 and the refrigerant flow channel, thereby reducing the space occupied by the integrated thermal management unit.

[0071] In one embodiment, the integrated thermal management unit further includes a gas-liquid separator 43, which is disposed on the refrigerant-side flow channel plate 4. The gas-liquid separator 43 is disposed on the refrigerant-side flow channel plate 4 and communicates with the refrigerant flow channel within the refrigerant-side flow channel plate 4, for separating liquid and gaseous refrigerant to protect the compressor 31. Exemplarily, along the left-right direction of the vehicle, the gas-liquid separator 43 is disposed on one side of the fan shroud 12, and the projection of the gas-liquid separator 43 at least partially overlaps with the projection of the fan shroud 12, thereby reducing the space occupied by the gas-liquid separator 43 along the front-rear direction of the vehicle.

[0072] Optionally, refer to Figure 1 The integrated thermal management unit also includes a water-side flow channel plate 5, which is located on the third wall 123 and has a coolant flow channel inside.

[0073] The water-side flow channel plate 5 is provided with a coolant flow channel. The coolant flow channel in the water-side flow channel plate 5 is used to hold the coolant. The coolant flow channel is integrated into the fan cover 12 through the water-side flow channel plate 5, which reduces the space occupied by the coolant flow channel and simplifies the pipeline setting of the coolant flow channel.

[0074] In one embodiment, along the airflow direction Y of the fan 11, the projection of the water-side flow channel plate 5 does not overlap with the projection of the fan 11, indicating that the water-side flow channel plate 5 will not block the fan 11, nor will it affect the air intake, air outlet and heat dissipation of the fan 11, thereby improving the heat dissipation efficiency.

[0075] Optionally, refer to Figure 1 Along the air outlet direction Y of fan 11, the projection of the water-side flow channel plate 5 does not overlap with the projection of the agent-side flow channel plate 4. Both the agent-side flow channel plate 4 and the water-side flow channel plate 5 are directly fixed to the third wall 123. That is to say, the agent-side flow channel plate 4 and the water-side flow channel plate 5 are laid flat on the third wall 123, thereby reducing the space occupied by the thermal management unit along the air outlet direction Y of fan 11.

[0076] In one specific embodiment, the fan 11 is offset. For example, the fan 11 is located on one side of the fan cover 12 in the left-right direction. The other side of the fan cover 12 will reserve space for the installation of the agent-side flow channel plate 4 and the water-side flow channel plate 5, so as to realize the integration of the agent-side flow channel plate 4 and the water-side flow channel plate 5 with the front-end module 1, thereby reducing the brackets and mounting beams required for the installation of the agent-side flow channel plate 4 and the water-side flow channel plate 5.

[0077] The water-side flow channel plate 5 may be provided with mounting positions for multi-way valves 51, water pumps 52, etc., for mounting components such as multi-way valves 51 and water pumps 52.

[0078] Optionally, refer to Figure 2 The integrated thermal management unit also includes a condenser 6, which is located on the side of the fourth wall 124 away from the third wall 123 and connected to the agent-side flow channel plate 4 or the fourth wall 124.

[0079] The condenser 6 is located on the side of the fan 11 in the Y-direction of the airflow direction, so that the fan 11 guides the airflow to the condenser 6, promoting heat dissipation and improving heat dissipation efficiency. At the same time, the condenser 6 is installed on one side of the fan shroud 12, which can reduce the space occupied by the entire thermal management integrated module.

[0080] For example, the condenser 6 is connected to the refrigerant-side flow channel plate 4 by a first bolt 64.

[0081] In another specific embodiment, the first direction X can be the vertical direction of the vehicle, the first wall 121 is located on the upper side of the fan cover 12, the second wall 122 is located on the lower side of the fan cover 12, the air conditioning unit 2 is located above the fan cover 12, and the compressor 31 is located below the fan cover 12; the air outlet direction Y of the fan 11 is the front-rear direction of the vehicle, the fourth wall 124 is located on the front side of the fan cover 12, the third wall 123 is located on the rear side of the fan cover 12, the condenser 6 is located on the front side of the fan cover 12, and the liquid-side flow channel plate 4 and the water-side flow channel plate 5 are located on the rear side of the fan cover 12, so that the condenser 6 can first contact the airflow blown in from the outside, thereby improving the heat dissipation efficiency of the condenser 6.

[0082] Optionally, refer to Figure 2 and Figure 3 The condenser 6 has a first interface 61, and the refrigerant-side flow channel plate 4 has a second interface 41 that communicates with the refrigerant flow channel. The first interface 61 and the second interface 41 are connected. The refrigerant-side flow channel plate 4 is connected to the first interface 61 of the condenser 6 through the second interface 41, thereby saving the piping connection between the refrigerant-side flow channel plate 4 and the condenser 6, thus reducing the space occupied by the integrated thermal management unit.

[0083] Optionally, refer to Figure 4 The condenser 6 includes multiple refrigerant pipes 62 and fins 63. The multiple refrigerant pipes 62 are all connected to the first interface 61. The fins 63 are located between two adjacent refrigerant pipes 62. The fins 63 include multiple first fins 631 and multiple second fins 632. Along the air outlet direction Y of the fan 11, the projections of the multiple first fins 631 overlap with the projection of the fan 11, and the projections of the multiple second fins 632 do not overlap with the projection of the fan 11. The maximum distance between two adjacent first fins 631 is less than the maximum distance between two adjacent second fins 632.

[0084] The refrigerant pipe 62 serves as the refrigerant flow channel, and fins 63 are arranged between two adjacent refrigerant pipes 62. When the airflow passes through the condenser 6, the fins 63 cause the air to pass through the fins 63 along a set path, ensuring that the air is in full contact with the fins 63, thereby increasing the effective heat dissipation area of ​​the condenser 6 and guiding and disturbing the air, so as to efficiently and quickly transfer the heat inside the refrigerant to the flowing air.

[0085] It should be understood that along the airflow direction Y of fan 11, the airflow in the area overlapping with the projection of fan 11 is stronger, while the airflow in the area not overlapping with the projection of fan 11 is relatively weaker. The spacing between the multiple second fins 632 in the area not overlapping with the projection of fan 11 is larger, that is, the multiple second fins 632 are set more sparsely. On the other hand, the maximum spacing between the multiple first fins 631 in the area overlapping with the projection of fan 11 is reduced, which is equivalent to setting the multiple first fins 631 more densely. This can make full use of the airflow in the area directly in front of fan 11, thereby improving heat dissipation efficiency.

[0086] Optionally, refer to Figure 1 and Figure 3 The integrated thermal management unit also includes a thermal management controller 7, which is located on the third wall 123. The thermal management controller 7 is integrated with the agent-side flow channel plate 4, the water-side flow channel plate 5, the air conditioning unit 2, and the compressor 31, reducing the connection length of pipelines and wiring harnesses between the above-mentioned devices and the thermal management controller 7, thereby improving the control accuracy of the thermal management controller 7 and reducing the energy loss of the thermal management system.

[0087] Secondly, embodiments of this application provide a vehicle that includes the integrated thermal management unit described in any of the above embodiments. The vehicle in this application, including the integrated thermal management unit described in any of the above embodiments, has the beneficial effects described in any of the above embodiments.

[0088] The integrated thermal management unit in this application is fixed to the vehicle body or front bulkhead through an installation point, which optimizes the spatial layout of the existing thermal management system, reduces the front compartment area occupied by the thermal management system, and can reduce the connection pipelines for refrigerant measurement, thereby optimizing the front compartment space of the vehicle, reducing the assembly time of the vehicle production line, and reducing costs.

[0089] In the integrated thermal management unit of this application, by integrating the air conditioning unit 2, the agent-side flow channel plate 4, the water-side flow channel plate 5, and the compressor 31 onto the fan cover 12 of the front module 1, the components of the thermal management system can be assembled completely, and then the integrated thermal management unit can be directly installed onto the fixed point of the vehicle body on the final assembly line. This improves the current problem of difficult and time-consuming assembly of thermal management system components. The compact design can also improve the space utilization of the thermal management system, thereby saving front compartment space.

[0090] In other words, by integrating the components of the thermal management system into a single integrated thermal management unit, the integrated thermal management unit can be directly installed into the front compartment during vehicle production, thereby improving the overall production efficiency of the vehicle. At the same time, it can also achieve refrigerant pre-charging before installation in the vehicle, improving the reliability of the integrated thermal management unit. Furthermore, the refrigerant-side flow channel plate 4 and the condenser 6 are directly connected through the second interface 41 and the first interface 61, reducing the traditional connecting pipes between the condenser 6 and the refrigerant-side flow channel plate 4, thereby reducing refrigerant leakage.

[0091] In addition, the compressor 31 and the compressor bracket 32 ​​are connected by shock-absorbing pads and bolts, and the connection between the integrated thermal management unit and the vehicle body can also be made by shock-absorbing pads and bolts, thereby improving the impact of vibration of the compressor 31, front-end module 1 and components in the air conditioning box 2 on the vehicle body.
