Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and mainly relates to a heat exchange component, a heater, a thermal management system, and a vehicle. Background Technology

[0002] With the rapid development of the new energy vehicle industry, its component technologies are constantly iterating and upgrading, with integration, lightweighting, and low cost becoming the core development directions. Among them, thick film heaters, as core components of the thermal management system of new energy vehicles, are playing an increasingly crucial role in ensuring vehicle performance and driving experience.

[0003] In related technologies, thick-film heaters typically use screws to fasten individual thick-film heating plates to cast aluminum water channels, forming a basic heat exchange unit. On one hand, the combination of an integrated die-cast aluminum flow channel and a screw-fastened individual thick-film heating plate results in a large overall product size and weight, making it difficult to meet the space and lightweight requirements of new energy vehicles. On the other hand, to prevent coolant leakage, additional sealing rings are required on top of the screw fastening, increasing both the number of parts and assembly complexity. Furthermore, the heater's heating efficiency is low, failing to meet the vehicle's thermal management requirements. Utility Model Content

[0004] In view of the problems existing in the background art, the present invention provides a heat exchange component, a heater, a thermal management system and a vehicle to solve the problems in the related art.

[0005] To solve the above problems, this utility model is implemented as follows:

[0007] The heat exchange plate is provided with a heat exchange medium flow channel. Along the first direction, the heat exchange medium flow channel passes through the heat exchange plate. The first heating plate and the second heating plate are respectively disposed on both sides of the heat exchange plate and are welded and fixed to the heat exchange plate as a whole.

[0008] Optionally, the heat exchange assembly further includes a heat exchange medium outlet pipe and a heat exchange medium inlet pipe, both of which extend along the first direction;

[0009] The first heating plate or the second heating plate has a first through hole and a second through hole, the heat exchange medium inlet pipe is connected to the first through hole, and the heat exchange medium outlet pipe is connected to the second through hole;

[0010] The first through hole is connected to the inlet of the heat exchange medium flow channel, and the second through hole is connected to the outlet of the heat exchange medium flow channel, so that both the heat exchange medium inlet pipe and the heat exchange medium outlet pipe are connected to the heat exchange medium flow channel.

[0011] Optionally, the heat exchange medium inlet pipe and the heat exchange medium outlet pipe are both welded together with the sidewalls forming the first through hole and the second through hole.

[0012] In a second aspect, this application provides a heater that includes the heat exchange assembly and housing assembly described in any of the preceding claims;

[0013] The housing assembly has a receiving cavity, and the heat exchange assembly is disposed in the receiving cavity.

[0014] Optionally, the heat exchange assembly further includes a heat exchange medium inlet pipe and a heat exchange medium outlet pipe, both of which extend along the first direction and are connected to the heat exchange medium flow channel.

[0015] The housing assembly includes two third through holes, and the heat exchange working fluid inlet pipe and the heat exchange working fluid outlet pipe are respectively passed through one of the third through holes;

[0016] A sealing element is provided between the third through hole and the heat exchange medium inlet pipe, and between the third through hole and the heat exchange medium outlet pipe.

[0017] Optionally, the seal is a sealing ring and / or sealant.

[0018] Optionally, the heater further includes a control component, which includes a connector and a controller, wherein the length direction of the housing assembly is a second direction and the width direction of the housing assembly is a third direction;

[0019] Along the second direction, the controller is disposed on one side outside the housing assembly, and the connector is electrically connected to the controller;

[0020] Along the third direction, the connector is disposed inside the housing assembly and on one side of the heat exchange plate, and the connector is electrically connected to the first heating plate and the second heating plate respectively.

[0021] Optionally, the housing assembly includes a housing, a cover plate, and a pressure plate;

[0022] The housing and the cover plate together form the receiving cavity. Along the first direction, the cover plate is disposed on one side of the housing, and the pressure plate is disposed on the side of the cover plate near the heat exchange plate.

The two heating plates are respectively positioned on both sides of the heat exchange plate and welded together along the thickness direction of the shell assembly (first direction). On one hand, the symmetrical layout and welded integration of the dual heating plates replaces the separate structure of a single heating plate and cast aluminum water channel fixed by screws in the prior art. This saves space occupied by fasteners such as screws and reduces the size of a single heating plate for the same power requirement, or increases the heating power density within the same volume, effectively reducing the overall size and weight of the product, making it more suitable for the lightweight and compact installation requirements of new energy vehicles. On the other hand, the welding and fixing method of the heating plate and the heat exchange plate directly achieves sealing at the connection point, eliminating the need for additional sealing rings as in related technologies. This not only reduces the number of parts but also eliminates the sealing ring assembly step, reducing assembly complexity. Simultaneously, the heat exchange medium flow channel runs through the heat exchange plate along the first direction, allowing the heat exchange medium to directly contact the first and second heating plates, significantly improving heat exchange efficiency.

Detailed Implementation

[0037] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. Based on the embodiments of the present utility model, any product that is the same as or similar to the present utility model, derived by anyone under the guidance of the present utility model or by combining the features of the present utility model with other related technologies, falls within the protection scope of the present utility model. Furthermore, all other embodiments obtained by those skilled in the art without inventive effort are within the protection scope of the present utility model.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but under appropriate circumstances, such techniques, methods, and equipment should be considered part of this utility model specification.

[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] Firstly, such as Figures 1 to 5As shown, this application provides a heat exchange assembly 100, which includes a first heating plate 101, a second heating plate 102, and a heat exchange plate 103. The thickness direction of the heat exchange plate 103 is a first direction X. A heat exchange medium flow channel 1031 is provided on the heat exchange plate 103. The heat exchange medium flow channel 1031 passes through the heat exchange plate 103 along the first direction. The first heating plate 101 and the second heating plate 102 are respectively disposed on both sides of the heat exchange plate 103 and are welded and fixed to the heat exchange plate 103 as a whole.

[0041] Specifically, the heat exchange assembly 100 in this application includes a first heating plate 101, a second heating plate 102, and a heat exchange plate 103. The first heating plate 101 and the second heating plate 102 can be thick film heating plates. The first heating plate 101 and the second heating plate 102 are respectively disposed on both sides of the heat exchange plate 103 along a first direction. A heat exchange medium flow channel 1031 is provided on the heat exchange plate 103. The length direction of the shell assembly 200 is a second direction. The heat exchange medium flow channel 1031 extends along the second direction. The heat exchange medium flow channel 1031 can be U-shaped. This application embodiment does not limit it.

[0042] Furthermore, both the first heating plate 101 and the second heating plate 102 are welded to the heat exchange plate 103, forming a seamless, sealed, integrated structure. Within this integrated structure, the heat exchange medium is guided by pre-defined flow channels 1031 on the heat exchange plate 103, which facilitate heat exchange with the first heating plate 101 and the second heating plate 102. The heat exchange medium can be a liquid or a gas; this embodiment does not limit its application. The first heating plate 101 and the second heating plate 102 can also be laser-welded to the heat exchange plate 103; this embodiment does not limit the specific welding method used.

[0043] Along the first direction, the heat exchange medium flow channel 1031 extends through the heat exchange plate 103. Specifically, along the first direction, the heat exchange medium flow channel 1031 extends through both sides of the heat exchange plate 103. The first heating plate 101 and the second heating plate 102 are respectively welded to both sides of the heat exchange plate 103 to seal the heat exchange medium flow channel 1031. The heat exchange medium flows within the through flow channel of the heat exchange plate 103 and between the first heating plate 101 and the second heating plate 102, and is in direct contact with the first heating plate 101 and the second heating plate 102. Heat does not need to be transferred through an additional carrier, reducing heat transfer loss and further improving heat exchange efficiency.

[0044] Understandably, on the one hand, by welding the two heating plates and the heat exchange plate 103 with flow channels into one piece, the separate structure of a single heating plate and cast aluminum water channel connected by screws in related technologies is replaced. This eliminates the need for additional fasteners such as screws, effectively reducing the space occupied by the structure. Under the premise of achieving the same heating power, the overall weight can be reduced and the size of the device can be decreased. On the other hand, the heating plates and heat exchange plate 103 are sealed by welding, eliminating the need for traditional sealing rings. This not only reduces the use of sealing rings, fixing screws, and other components, but also eliminates the need for sealing ring assembly and screw tightening, simplifying the assembly process and improving assembly efficiency. Simultaneously, it avoids the problem of heat exchange medium leakage that may be caused by the aging and failure of the sealing ring after long-term use, enhancing the sealing reliability of the device. The heat exchange medium flow channel 1031 runs through the heat exchange plate 103 along the first direction. This through-flow channel allows the heat exchange medium to pass directly through the heat exchange plate 103 along the first direction, enabling the heat exchange medium to fully contact the heating plates on both sides during flow, significantly increasing the heat exchange area, reducing intermediate heat transfer losses, and significantly improving heat exchange efficiency.

[0045] Optionally, such as Figures 1 to 7 As shown, the heat exchange assembly 100 further includes a heat exchange medium outlet pipe 104 and a heat exchange medium inlet pipe 105, both extending along a first direction. The first heating plate 101 or the second heating plate 102 has a first through hole 106 and a second through hole 107. The heat exchange medium inlet pipe 105 communicates with the first through hole 106, and the heat exchange medium outlet pipe 104 communicates with the second through hole 107. The first through hole 106 communicates with the inlet of the heat exchange medium flow channel 1031, and the second through hole 107 communicates with the outlet of the heat exchange medium flow channel 1031, so that both the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 are connected to the heat exchange medium flow channel 1031.

[0046] Specifically, the heat exchange assembly also includes a heat exchange medium inlet pipe 105 and a heat exchange medium outlet pipe 104 for inputting and outputting the heat exchange medium. A first through hole 106 and a second through hole 107 are formed on the first heating plate 101 or the second heating plate 102. The first through hole 106 corresponds to the inlet of the heat exchange medium flow channel 1031 in the heat exchange plate 103, and the second through hole 107 corresponds to the outlet end of the flow channel. During assembly, one end of the heat exchange medium inlet pipe 105 is connected to the first through hole 106, so that the internal channel of the inlet pipe is connected to the inlet of the heat exchange medium flow channel 1031. One end of the heat exchange medium outlet pipe 104 is connected to the second through hole 107, so that the internal channel of the outlet pipe is connected to the outlet of the heat exchange medium flow channel 1031. This ensures a complete path for the heat exchange medium to flow in from the heat exchange medium inlet pipe 105, undergo heat exchange through the heat exchange medium flow channel 1031 on the heat exchange plate 103, and then flow out from the heat exchange medium outlet pipe 104.

[0047] Understandably, the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 are directly connected to the first through hole 106 and the second through hole 107, respectively, which shortens the flow path of the working medium. The heat exchange medium can flow in from the heat exchange medium inlet pipe 105, exchange heat through the heat exchange medium flow channel 1031 on the heat exchange plate 103, and then flow out from the heat exchange medium outlet pipe 104. This avoids pressure loss caused by detours and makes the flow of the working medium smoother, which helps to improve the heat exchange efficiency.

[0048] Optionally, the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 are both welded together with the sidewalls forming the first through hole 106 and the second through hole 107.

[0049] Specifically, the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 are welded together with the sidewalls forming the first through hole 106 and the second through hole 107. During the welding process, the connection between the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 and the heating plate forms a continuous and sealed weld, which together with the first heating plate 101, the second heating plate 102 and the heat exchange plate 103 constitutes an integrated heat exchange assembly 100. The heat exchange medium inlet pipe 105, the heat exchange medium outlet pipe 104 and the heat exchange plate 103 can be made of stainless steel to ensure the reliability of the welding.

[0050] Understandably, on the one hand, the heat exchange medium inlet pipe 105 and heat exchange medium outlet pipe 104 are welded to the heat exchange assembly 100 to form an integrated structure. The sealing of the weld can avoid the risk of leakage of the heat exchange medium at the interface, eliminating the need for additional sealing components such as sealing rings, reducing the number of parts and assembly steps, and lowering the probability of failure due to aging of the seal 202. At the same time, the welded integrated structure enhances the connection strength between the heat exchange medium inlet pipe 105, heat exchange medium outlet pipe 104 and heat exchange assembly 100, and can better withstand the pressure impact during medium flow and the vibration during vehicle operation, improving the structural stability and service life of the heater, and adapting to the complex operating environment of new energy vehicles.

[0051] like Figure 1 and Figure 6 As shown, in a second aspect, this application provides a heater, which includes the heat exchange assembly 100 and the housing assembly 200 described in any of the above claims; the housing assembly 200 has a receiving cavity in which the heat exchange assembly 100 is disposed.

[0052] Specifically, the shell assembly 100 serves as a carrier that combines assembly positioning and protection functions. It has an internal cavity that is adapted to the external dimensions and structural contour of the heat exchange assembly 200. The space of this cavity can not only achieve the stable placement and positioning of the heat exchange assembly 200, ensuring that the two fit tightly without loosening or displacement after assembly, but also, with the help of the shell assembly 100's own closed structure and solid shell, build a reliable protective barrier for the heat exchange assembly 200 placed inside, effectively isolating it from the erosion of dust, water vapor and other impurities in the external environment, while resisting mechanical damage such as accidental collisions and impacts, thereby ensuring that the heat exchange assembly 200 can maintain a stable operating state and heat exchange performance under complex working conditions.

[0053] Optionally, the heat exchange assembly 100 further includes a heat exchange medium inlet pipe 105 and a heat exchange medium outlet pipe 104, both extending along a first direction and communicating with the heat exchange medium flow channel 1031; the shell assembly 200 includes two third through holes 201, with the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 passing through one third through hole 201 respectively; a sealing element 202 is provided between the third through hole 201 and the heat exchange medium inlet pipe 105, and between the third through hole 201 and the heat exchange medium outlet pipe 104.

[0054] Specifically, two third through holes 201 are machined on the sidewall of the shell assembly 200 at positions corresponding to the first through hole 106 and the second through hole 107. The positions of the two third through holes 201 correspond to the extension directions of the heat exchanger inlet pipe 105 and the heat exchanger outlet pipe 104 on the heat exchanger assembly 100. The diameter of the holes is slightly larger than the outer diameter of the heat exchanger inlet pipe 105 and the heat exchanger outlet pipe 104 to accommodate insertion. During assembly, the heat exchanger inlet pipe 105 communicates with the first through hole 106, passes through one of the third through holes 201 from inside the shell assembly 200, and extends to the outside of the shell assembly 200. The heat exchanger outlet pipe 104 communicates with the second through hole 107, passes through the other third through hole 201 from inside the shell assembly 200, and extends to the outside of the shell assembly 200. A suitable gap is maintained between the heat exchanger inlet pipe 105 and the heat exchanger outlet pipe 104 and the third through holes 201 to meet the insertion requirements.

[0055] The sealing element 202 is disposed between the heat exchange medium inlet pipe 105 and the third through hole 201 through which it passes, and between the heat exchange medium outlet pipe 104 and the third through hole 201 through which it passes, so that the sealing element 202 is in close contact with the outer wall of the heat exchange medium inlet pipe 105, the outer wall of the heat exchange medium outlet pipe 104, and the inner wall of the third through hole 201, forming a reliable annular sealing structure. Understandably, the two third through holes 201 of the housing assembly 200 provide passageways for the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104, preventing interference with other components of the housing due to positional shifts during assembly or use, and ensuring the stability of the working medium flow path. On the other hand, the third through hole 201 limits the heat exchange medium inlet pipe 105 and heat exchange medium outlet pipe 104, simplifies the alignment process of the heat exchange medium inlet pipe 105 and heat exchange medium outlet pipe 104 with the heat exchange component 100 during assembly, improves assembly efficiency, and makes the extension of the heat exchange medium inlet pipe 105 and heat exchange medium outlet pipe 104 inside and outside the housing component 200 more regular, reducing the messy layout in the limited installation space of the car.

[0056] The seals 202 fill the gaps between the third through hole 201 and the heat exchange medium inlet pipe 105, and between the third through hole 201 and the heat exchange medium outlet pipe 104, respectively. If the heat exchange medium leaks from the heat exchange assembly 100, they can block the path of leakage from the heat exchange medium through the aforementioned gaps, compensating for potential sealing leaks that may exist if only pipes are installed or welded, further enhancing the overall sealing performance of the heater and preventing the heating function from being affected or the surrounding components from being damaged due to heat exchange medium leakage. At the same time, the seals 202 can buffer the relative displacement of the heat exchange medium inlet pipe 105, the heat exchange medium outlet pipe 104, and the shell assembly 200 caused by vibration during vehicle operation, reducing pipe wear or shell through hole deformation caused by rigid contact, and ensuring that the sealing structure remains stable under dynamic operating conditions. In addition, the seals 202 can also prevent dust, water vapor, and other impurities in the external environment from entering the interior of the shell assembly 200 through the gaps, preventing impurities from adhering to the surface of the heat exchange assembly 100 and affecting heat exchange efficiency, or corroding core components and shortening their service life.

[0057] Optionally, the seal 202 is a sealing ring and / or sealant.

[0058] Specifically, the seal 202 can be a sealing ring or sealant, or both. When the seal 202 is a sealing ring, it is respectively positioned in the gap between the third through hole 201 of the housing assembly 200 and the heat exchange medium inlet pipe 105, and in the gap between the third through hole 201 and the heat exchange medium outlet pipe 104. By adjusting the size of the sealing ring, it is made to fit tightly against the inner wall of the third through hole 201, the outer wall of the heat exchange medium inlet pipe 105, and the outer wall of the heat exchange medium outlet pipe 104. The elastic deformation of the sealing ring itself fills the gaps, forming a reliable sealing structure. During assembly, the sealing ring is first fitted into the preset positions of the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104, and then the heat exchange medium inlet pipe 105 and the heat exchange medium outlet pipe 104 are respectively passed through one of the third through holes 201. When sealant is used for sealing component 202, after the heat exchange medium inlet pipe 105 and heat exchange medium outlet pipe 104 are respectively inserted into one of the third through holes 201, sealant is injected into the gaps between the third through hole 201 and the heat exchange medium inlet pipe 105 and the gaps between the third through hole 201 and the heat exchange medium outlet pipe 104 of the housing assembly 200, ensuring that the sealant completely covers all contact surfaces in the gaps. After the sealant cures, an integral sealing layer that is tightly bonded to the contact surfaces is formed at each gap, thereby sealing the gaps. When the seal 202 serves as both a sealing ring and a sealant, the sealing ring is first placed in the gaps between the third through hole 201 of the housing assembly 200 and the heat exchange medium inlet pipe 105, and between the third through hole 201 and the heat exchange medium outlet pipe 104. Then, sealant is injected into the remaining space between the sealing ring and the inner wall of the gap. After the sealant cures, the sealing ring initially seals through elastic deformation, while the sealant fills the remaining gaps and forms an integral whole with the sealing ring and the contact surface, thus forming a double sealing structure.

[0059] Understandably, the seal 202 adopts a combination of sealing rings and / or sealant, allowing for flexible selection of the sealing method according to different operating conditions. When using only a sealing ring, it can quickly achieve sealing through elastic deformation and is easy to disassemble and maintain. When using only sealant, it can form a gapless integral sealing layer, adapting to complex gap shapes. When the two are combined, they can leverage the elastic buffering of the sealing ring and the comprehensive filling advantage of the sealant, achieving dual protection and significantly improving sealing reliability. At the same time, regardless of the form used, it can effectively block the leakage path of the heat exchange medium, buffer the vibration and friction between the pipe and the shell assembly 200, and prevent the intrusion of external impurities.

[0060] Optionally, such as Figures 1 to 3As shown, the heater also includes a control component 300, which includes a connector 301 and a controller 302. The length direction of the housing component 200 is a second direction, and the width direction of the housing component 200 is a third direction. Along the second direction, the controller 302 is disposed on one side outside the housing component 200, and the connector 301 is electrically connected to the controller 302. Along the third direction, the connector 301 is disposed inside the housing component 200 and is disposed on one side of the heat exchange plate 103. The connector 301 is electrically connected to the first heating plate 101 and the second heating plate 102 respectively.

[0061] Specifically, the length direction of the heater housing assembly 200 is the second direction, and the width direction is the third direction. Along the second direction, the controller 302 is located on the outer side of the housing assembly 200, while the connector 301 is located inside the housing assembly 200. The two are electrically connected to ensure stable transmission of current and signals inside and outside the housing. Along the third direction, the connector 301 is arranged inside the housing assembly 200 on one side corresponding to the heat exchange plate 103, and is electrically connected to the first heating plate 101 and the second heating plate 102 respectively, forming an electrical conduction path for the controller 302 outside the housing, the connector 301 inside the housing, and the two heating plates.

[0062] Understandably, connector 301 electrically connects the first heating plate 101 and the second heating plate 102, and forms a complete electrical conduction path with the controller 302. This allows the controller 302 to transmit unified and synchronous electrical signals and current to the two heating plates, avoiding control delays and power deviations that may occur when the two heating plates are individually connected to the controller 302. This ensures that the two heating plates can start and stop synchronously and adjust their heating power according to the controller 302's instructions, thereby ensuring the uniformity of heating of the heat exchange medium by the heat exchange component 100. At the same time, by centrally establishing the electrical connection through connector 301, the dispersed design of the external wiring of the two heating plates is replaced, greatly simplifying the electrical connection structure within the housing, reducing wiring redundancy and layout complexity, and lowering the risk of poor contact and short circuits caused by excessive wiring. This ensures that the current can be stably and efficiently transmitted from the controller 302 to the two heating plates, guaranteeing accurate output of heating power. The controller 302 is located outside the housing assembly 200, away from the heat-generating area of ​​the heat exchange assembly 100 inside the housing, avoiding the impact of high temperature on the electronic components of the controller 302. At the same time, it facilitates the heat dissipation and later maintenance of the controller 302, improving its working stability and service life. The connector 301 is located inside the housing assembly 200, which can isolate external dust, moisture and other impurities through the protective function of the housing, protecting its electrical connection parts with the two heating plates from corrosion and reducing the risk of poor contact.

[0063] Optionally, such as Figure 3As shown, the control component 300 also includes a first connector 603 and a second connector 604; along the second direction, the first connector 603 and the second connector 604 are disposed on the same side as the controller 302, and both the first connector 603 and the second connector 604 are electrically connected to the controller 302.

[0064] Specifically, the control assembly 300 further includes a first connector 603 and a second connector 604. The length direction of the heater housing assembly 200 is a second direction, and the controller 302 is disposed on the outer side of the housing assembly 200 along the second direction. The first connector 603 and the second connector 604 are arranged on the same side of the housing assembly 200 as the controller 302, specifically, they can be installed on the end face or side of the controller 302 near the housing assembly 200. Both connectors are electrically connected to the controller 302, forming an electrical conduction path between the external system and the controller 302. The first connector 603 and the second connector 604 are respectively a high-voltage connector and a low-voltage connector.

[0065] Understandably, placing the first connector 603, the second connector 604, and the controller 302 on the same side along the second direction allows for concentrated use of space on one side of the housing assembly 200, avoiding space waste caused by components being scattered on both sides of the housing assembly 200. Simultaneously, this same-side arrangement eliminates the need for external cables to cross both sides of the housing assembly 200, simplifying the assembly process between the heater and external systems. Later maintenance only requires operation on one side, improving maintenance convenience. Furthermore, the same-side placement of the connectors and controller 302 shortens the length of the electrical connection lines between them, reducing transmission losses and electromagnetic interference, ensuring stable transmission of electrical signals and current, and further improving the controller 302's control accuracy over the heating plate.

[0066] Optionally, such as Figure 4 and Figure 5 As shown, the housing assembly 200 includes a housing 203, a cover plate 204, and a pressure plate 205; the housing 203 and the cover plate 204 together form a receiving cavity. Along the first direction, the cover plate 204 is located on the side of the housing 203 away from the heat exchange medium inlet pipe 105, and the pressure plate 205 is located on the side of the cover plate 204 close to the heat exchange plate 103. The pressure plate 205 is fixedly connected to the cover plate 204.

[0067] Specifically, the housing assembly 200 consists of a housing 203, a cover plate 204, and a pressure plate 205. The housing 203 has a recessed structure, and the cover plate 204 is connected to the opening of the recessed structure to form the receiving cavity together with the housing 203. A third through hole 201 is formed at the bottom of the recessed structure. Along the first direction, the cover plate 204 is located on the side of the housing 203 away from the heat exchange medium inlet pipe 105, and the pressure plate 205 is located on the side of the cover plate 204 close to the heat exchange plate 103. The pressure plate 205 is fixedly connected to the cover plate 204. At the same time, the pressure plate 205 is located on the side of the cover plate 204 close to the heat exchange plate 103 and can be fixed to the cover plate 204 by means of screw connection or welding. This application does not limit its fixing method, and the position of the pressure plate 205 corresponds to the heat exchange plate 103 to form an auxiliary limit on the heat exchange plate 103 after the cover plate 204 is assembled.

[0068] When the sealing element 202 is a sealing ring and sealant, during assembly, first, the heat exchanger inlet pipe 105, the heat exchanger outlet pipe 104, and the heat exchange assembly 100 are welded together as a single piece. Sealing rings are then fitted at predetermined positions on the heat exchanger inlet pipe 105 and the heat exchanger outlet pipe 104, and inserted through the opening side of the housing 203, ensuring that the heat exchanger inlet pipe 105 and the heat exchanger outlet pipe 104 pass through the third through hole 201. Sealant is then filled into the gaps between the third through hole 201 and the heat exchanger inlet pipe 105, and between the third through hole 201 and the heat exchanger outlet pipe 104. Then, the pressure plate 205 is fixed to the cover plate 204, and finally, the cover plate 204 is fixed to the housing 203. In some embodiments, the cover plate 204 and the housing 203 can be further sealed by applying sealant.

[0069] Understandably, arranging the housing 203, cover plate 204, and pressure plate 205 in layers along the first direction fully utilizes the space in the thickness direction of the housing assembly 200, avoids excessive extension of components in the length or width direction, and effectively controls the overall volume of the housing assembly 200. After the pressure plate 205 is fixedly connected to the cover plate 204, it can stably limit the heat exchange plate 103 in the heat exchange assembly 100, preventing the heat exchange assembly 100 from shifting due to vibration during vehicle operation, and ensuring the stability of the connection between the heat exchange medium flow channel 1031 and the heat exchange medium inlet pipe 105 and outlet pipe. At the same time, the cover plate 204 covering the opening of the housing 203 can isolate external dust and moisture, protecting the internal heat exchange assembly 100 and electrical connection components, while the presence of the pressure plate 205 can enhance the structural strength of the cover plate 204, preventing the cover plate 204 from deforming under external force or temperature changes, further improving the protective performance and overall stability of the housing assembly 200.

[0070] Thirdly, this application provides a thermal management system, which includes the heat exchange component 100 or the heater described in any of the above claims; and a thermal management controller electrically connected to the heat exchange component 100 or the heater.

[0071] The thermal management system provided in this application, by employing the aforementioned heat exchange component 100, which combines high-efficiency heat exchange performance with a stable structure, or a heater integrating the heat exchange component, and in conjunction with the thermal management controller 302 electrically connected thereto, can fully leverage the advantages of the heat exchange component 100 (or heater) in terms of heat exchange efficiency and assembly reliability. At the same time, by using the thermal management controller 302 to regulate the heat exchange component 100 (or heater), flexible and efficient control of the heat exchange process within the system can be achieved. The optimized structure of the heat exchange component 100 (or heater) ensures the stability and efficiency of heat transfer, meeting the thermal management needs under different scenarios. Furthermore, the intelligent adaptive control of the thermal management controller 302 improves the controllability and energy efficiency of the entire thermal management system, effectively avoiding problems such as heat waste or insufficient supply.

[0072] Fourthly, this application also provides a vehicle comprising the heat exchange assembly 100 described in any of the preceding claims, or the heater described in any of the preceding claims, or the thermal management system described in the preceding claims.

[0073] Specifically, the vehicle provided in this application, by equipping the aforementioned heat exchange component 100 with high-efficiency heat exchange performance and stable structure, or a reliable heater or thermal management system integrating the heat exchange component, can effectively meet the vehicle's thermal management needs under different operating conditions (such as low-temperature start-up, high-temperature heat dissipation, cabin temperature control, and power battery thermal management). The optimized design of the core heat exchange / heating components ensures the timeliness and efficiency of heat supply and regulation, avoiding the impact of temperature issues on the performance and lifespan of key vehicle components (such as batteries and motors). Furthermore, the mature thermal management system architecture improves the accuracy and energy efficiency of the vehicle's thermal management, reducing energy consumption. At the same time, relying on the stable structural reliability of each component, it reduces the risk of vehicle thermal management-related failures, ultimately helping the vehicle maintain a better operating state, ride comfort, and overall energy efficiency in complex driving environments.
