Description

Technical Field

[0001] This application relates to the field of heat exchange equipment technology, and more specifically, to a heat exchanger, a temperature control system, and an energy storage device. Background Technology

[0002] With increasing demands for energy efficiency and growing process complexity, multi-media heat exchange is becoming increasingly common. In multi-media heat exchange, the traditional heat exchange path design is limited. Because the areas formed by the heat exchange paths of different heat exchange media overlap, the heat exchange processes can interfere with each other, affecting the heat exchanger's efficiency. Utility Model Content

[0003] This application provides a heat exchanger, a temperature control system, and an energy storage device, which can reduce the mutual influence of heat exchange processes of different heat exchange media and improve the independence of each heat exchange process.

[0004] In a first aspect, this application provides a heat exchanger including a plurality of heat exchange sections, which are arranged along a first direction and spaced apart along the first direction. The plurality of heat exchange sections are not interconnected, and each heat exchange section extends along a second direction. At least two heat exchange sections contain different heat exchange media. The first direction is perpendicular to the second direction.

[0005] In this embodiment, the heat exchanger uses multiple independent heat exchange sections that extend along a second direction and contain different heat exchange media, arranged at intervals along a first direction perpendicular to the second direction, thus achieving mutual isolation between the heat exchange sections. The independent heat exchange sections eliminate cross-contact and mixing between different heat exchange media, avoiding the risk of chemical reactions, contamination, or performance failure due to differences in media properties. The spaced arrangement blocks heat conduction and convection interference between heat exchange sections, preventing heat from the high-temperature heat exchange section from diffusing to the low-temperature heat exchange section without effective utilization. This allows each heat exchange section to operate independently and stably based on its own media characteristics and process requirements. The heat exchange process is unaffected by changes in the temperature field and flow rate of adjacent heat exchange sections, improving the accuracy and reliability of multi-media parallel heat exchange.

[0006] In some embodiments of the first aspect, the heat exchanger further includes: a first manifold extending along a first direction, the first manifold including a plurality of non-communicating first chambers, one end of the heat exchange section being connected to the first chambers.

[0007] In this embodiment, the heat exchanger incorporates a first manifold extending along a first direction and containing multiple non-interconnected first chambers. Each heat exchange section has one end connected to a specific chamber, enabling precise and independent distribution and collection of multiple media. The first chambers are connected to one end of the heat exchange section, allowing for directional transport of the heat exchange medium and preventing distribution disorder. Its modular chamber design utilizes standardized partitions and sealing structures, significantly simplifying the manufacturing process and reducing processing complexity and assembly difficulty through prefabrication and on-site assembly. Each chamber shares a common manifold shell, reducing the use of additional connectors and shell material compared to traditional single-medium independent pipes or complex compartmentalized structures.

[0008] In some embodiments of the first aspect, the heat exchanger further includes: a second manifold extending along a first direction, the second manifold including a plurality of non-communicating second chambers; wherein the first manifold and the second manifold are located on opposite sides of the heat exchange section along a second direction, and the other end of the heat exchange section is connected to the second chambers.

[0009] In this embodiment, a second manifold is added opposite to the first manifold, achieving closed-loop independent management of multiple media inputs and outputs. Each medium flows into the heat exchange section from its corresponding first chamber, and after heat exchange, flows out from the matched second chamber, completely avoiding cross-mixing. The symmetrical layout effectively balances the pressure on both sides of the heat exchange section, improving the stability of the heat exchanger. The first and second chambers have similar structures and uniform manufacturing processes, employing standardized processing and modular design, sharing molds to reduce customization costs. The dual manifolds form a symmetrical "input-output" closed-loop structure, with each first chamber corresponding to a second chamber, making the path of each heat exchange medium from entry to exit clearly traceable. This allows for rapid confirmation of the heat exchange medium flow direction, avoiding the risk of medium confusion in traditional complex pipelines.

[0010] In some embodiments of the first aspect, the heat exchange section includes a plurality of heat exchange plates spaced apart along a first direction, the plurality of heat exchange plates being non-communicating with each other, the heat exchange plates extending along a second direction, and the heat exchange plates being used to exchange heat with the heat exchange medium within the heat exchange plates; wherein, one end of the heat exchange plate is connected to a first chamber, and the other end of the heat exchange plate is connected to a second chamber.

[0011] In this embodiment, the heat exchanger is designed with multiple heat exchange plates spaced apart along a first direction and not interconnected, connected to the corresponding chambers of the first and second manifolds. The cooperation between the multiple heat exchange plates and the manifold chambers achieves uniform distribution of the heat exchange medium: the first chamber evenly distributes the heat exchange medium to the inlet of each heat exchange plate, and the flow rate of the heat exchange medium is consistent through multiple identical heat exchange plates; the second manifold synchronously and evenly collects the heat exchange medium after heat exchange, avoiding uneven heat exchange caused by excessive or insufficient local flow.

[0012] In some embodiments of the first aspect, the first heat exchange section among the plurality of heat exchange sections includes a first heat exchange plate group and a second heat exchange plate group arranged along a first direction. The first heat exchange plate group connects a first sub-chamber and a second chamber, and the second heat exchange plate group connects a second sub-chamber and a second chamber. The flow directions of the heat exchange medium in the first heat exchange plate group and the second heat exchange plate group are opposite. The first sub-chamber and the second sub-chamber are chambers in the first chamber that are not interconnected.

[0013] In this embodiment, the first chamber is divided into a first sub-chamber and a second sub-chamber. The heat exchange medium enters through the first sub-chamber, flows sequentially through the first heat exchange plate group, the second chamber, and the second heat exchange plate group, and finally flows out from the second sub-chamber. During this process, the medium flows in opposite directions within the two sets of heat exchange plates, which improves the heat exchange temperature difference and heat transfer efficiency. The independent sub-chambers avoid the risk of medium mixing and improve the accuracy of heat exchange control.

[0014] In some embodiments of the first aspect, the first manifold further includes a plurality of third chambers, which are not connected to the first chambers and are adjacent to the first chambers. The second heat exchange section among the plurality of heat exchange sections includes a first heat exchange channel, a second heat exchange channel and a third heat exchange channel. One end of the first heat exchange channel is connected to the first chamber, one end of the second heat exchange channel is connected to the third chamber, and the other end of the first heat exchange channel is connected to the other end of the second heat exchange channel through the third heat exchange channel. The third heat exchange channel and the first manifold are arranged opposite to each other along the second direction.

[0015] In this embodiment, by setting up independent first and third chambers within the first manifold, the heat exchange medium enters the first chamber, flows through the heat exchange section to the third chamber, and finally exits from the second connection port. This unidirectional flow path, combined with the counter-current flow design of the heat exchange section, maximizes the temperature difference between the hot and cold media, enhancing heat transfer. The physical isolation between the chambers avoids the risk of media cross-flow and contamination, and the independent chambers facilitate maintenance. Furthermore, this structure supports independent parallel heat exchange of multiple media, flexibly adapting to heat exchange requirements under different operating conditions, combining high efficiency and practicality.

[0016] In some embodiments of the first aspect, the heat exchanger further includes a plurality of first connection ports and a plurality of second connection ports, wherein the first connection ports are used to supply heat exchange medium to the heat exchange section, and the second connection ports are used to discharge heat exchange medium; wherein the number of first connection ports is greater than or equal to the number of heat exchange sections, and the number of second connection ports is greater than or equal to the number of heat exchange sections.

[0017] In this embodiment, by setting a number of first and second connection ports no less than the number of heat exchanger types, an independent transport channel is provided for each heat exchange medium, avoiding the risk of cross-contamination or mixing of different media due to shared interfaces. The redundant interface design supports flexible system expansion; when a new type of heat exchange medium is added, it can be directly connected to a backup interface without modifying the original pipeline, significantly shortening system upgrade time. The clear correspondence not only reduces customization costs and installation difficulty but also facilitates quick location of faulty flow paths through interface identification, improving equipment maintenance efficiency.

[0018] In some embodiments of the first aspect, each heat exchange plate includes a plurality of partitions spaced apart along a third direction, the partitions extending along a second direction to divide the heat exchange plate into a plurality of flow channels, and the plurality of flow channels are not interconnected; wherein, the third direction is the thickness direction of the heat exchange portion, and the first direction, the second direction and the third direction are perpendicular to each other.

[0019] In this embodiment, the heat exchanger's heat exchange plates form multiple independent, non-interconnected flow channels through internal baffles arranged at intervals along a third direction and extending along a second direction, thereby improving heat exchange performance and management flexibility. The multiple flow channels achieve uniform distribution of the heat exchange medium, avoiding the uneven flow rate problem of traditional single-channel systems, ensuring full contact between the medium and the heat exchange plates, and significantly enhancing the heat exchange effect.

[0020] In some embodiments of the first aspect, the heat exchanger further includes a heat dissipation structure located between two adjacent heat exchange plates.

[0021] In this embodiment, a heat dissipation structure is added between adjacent heat exchange plates to optimize the heat exchanger's thermal management performance. The heat dissipation structure can quickly conduct heat from the heat exchange plates through fins or highly thermally conductive materials, rapidly dissipating the heat to the outside and enhancing the heat dissipation efficiency of the heat exchange plates.

[0022] In some embodiments of the first aspect, the heat exchanger further includes a ventilation device for accelerating the cooling or heating of the heat exchange medium within the heat exchange section.

[0023] In this embodiment, the heat exchanger incorporates ventilation equipment and utilizes a fan connected to the heat exchange section via ductwork and a flow-guiding design to achieve co-current, counter-current, or cross-current heat exchange between the airflow and the heat exchange medium. This effectively enhances heat transfer between the media, significantly improves heat exchange efficiency, and enables rapid cooling or heating of the medium. This expands the application scenarios of the heat exchanger and improves its practicality and adaptability.

[0024] In a second aspect, this application provides a temperature control system, comprising: a heat exchange device for exchanging heat with a heat source or a cold source; and the heat exchanger in the first aspect for heating or cooling the heat exchange medium within the heat exchange device.

[0025] Thirdly, this application provides an energy storage device, including a battery device and the temperature control system mentioned in the second aspect, wherein the battery device is used to provide electrical energy. Attached Figure Description

[0045] In some embodiments, the battery device may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or in a mixed configuration via a busbar.

[0046] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0047] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0048] In some embodiments, the battery device may be a battery pack, which includes a battery housing and one or more individual battery cells housed within the battery housing.

[0049] As an example, a battery cell assembly can be a battery module, which can be housed in a battery housing by fixing the battery module in the battery housing.

[0050] As an example, battery cell assemblies can also be housed in a battery housing by directly fixing multiple battery cells to the battery housing.

[0051] As an example, the battery housing may include a first battery housing and a second battery housing portion. The first battery housing portion and the second battery housing portion are fastened together to form a closed space inside the battery housing for housing individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first battery housing may be a top cover or a bottom plate.

[0052] As an example, the battery enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are respectively connected to the frame, so that the interior of the battery enclosure forms an enclosed space to house individual battery cells.

[0053] In some embodiments, the energy storage device may include one or more battery clusters to increase the voltage and capacity of the energy storage device. A battery cluster may include multiple battery devices connected in series via a busbar to increase the voltage of the energy storage device. When the energy storage device includes multiple battery clusters, the battery clusters are connected in parallel to increase the capacity of the energy storage device.

[0054] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage devices can store electrical energy as needed and output it when appropriate. For example, an energy storage device can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. The energy storage system provided in this application embodiment can be any power system that requires energy storage devices.

[0055] In some embodiments, the energy storage device is an energy storage container or an energy storage cabinet.

[0056] In some embodiments, the energy storage device may include a cabinet and one or more battery clusters housed within the cabinet.

[0057] In some embodiments, the energy storage device may include modules such as a thermal management module, a main control module, a central control module, a power distribution module, and a fire protection module.

[0058] As an example, the thermal management module may include a liquid cooling unit that supplies coolant to each battery device via piping to regulate the temperature of the individual battery cells.

[0059] As an example, the main control module can serve as the battery management unit for the battery cluster, used to monitor and manage the battery cluster. The main control module can monitor information such as the current, voltage, power, or temperature of the battery cluster. For instance, it can control the charging and discharging current and voltage of the battery cluster. The main control module includes modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0060] As an example, the central control module can serve as the battery management unit for an energy storage device, used to monitor and manage the device. The central control module can monitor information such as the energy storage device's current, voltage, power, state of charge, or temperature. For instance, it can control the charging and discharging current and voltage of the energy storage device.

The power generation device generates electrical energy, which can be stored in the energy storage device via the power converter. For example, the power generation device may specifically be a solar panel, a hydroelectric power generation device, a thermal power generation device, a wind power generation device, etc. The specific type of power generation device is not limited in this application.

[0064] With increasing demands for energy efficiency and growing process complexity, multi-media heat exchange is becoming increasingly common. In multi-media heat exchange, the traditional heat exchange path design is limited. Because the areas formed by the heat exchange paths of different heat exchange media overlap, the heat exchange processes can interfere with each other, affecting the heat exchanger's efficiency.

[0065] Based on the above considerations, this application provides a battery housing that can solve the problem that individual battery cells in the battery housing are prone to deformation or even damage due to excessive local pressure. The heat exchanger provided in this application includes multiple heat exchange sections extending along a first direction, which are not interconnected, and at least two heat exchange sections contain different heat exchange media; wherein the multiple heat exchange sections are arranged along a second direction and spaced apart along the second direction, and the first direction is perpendicular to the second direction.

[0066] In this embodiment, the heat exchanger utilizes multiple independent heat exchange sections that extend along a first direction and contain different heat exchange media, arranged at intervals along a second direction perpendicular to the first direction, thus achieving mutual isolation between the heat exchange sections. The independent heat exchange sections eliminate cross-contact and mixing between different heat exchange media, avoiding the risks of chemical reactions, contamination, or performance failure caused by differences in media properties. The spaced arrangement blocks heat conduction and convection interference between heat exchange sections, preventing heat from the high-temperature heat exchange section from diffusing to the low-temperature heat exchange section without effective utilization. This allows each heat exchange section to operate independently and stably based on its own media characteristics and process requirements. The heat exchange process is unaffected by changes in the temperature field and flow rate of adjacent heat exchange sections, improving the accuracy and reliability of multi-media parallel heat exchange.

[0067] Figure 1 This is a schematic diagram of the heat exchange system according to an embodiment of this application. Figure 1As shown, in the heat exchange system 1000, a liquid pump 200 supplies heat exchange medium to equipment requiring heat exchange, such as battery devices, power conversion devices in energy storage systems, etc., and a liquid valve 400 controls the flow of the heat exchange medium. After the heat exchange medium acts on the equipment, heat exchange occurs through a cooling water tank 300. Additionally, the battery device can be cooled by an air conditioning system 500, where the cooling water tank 300 acts as a condenser. The heat exchange medium for the battery device is water or ethylene glycol. In this heat exchange system 1000, the heat exchange medium for the power conversion device is coolant, and the heat exchange medium in the air conditioning system 500 is Freon. Different cooling water tanks 300 are required for different heat exchange media, or a single heat exchanger can simultaneously exchange heat from all three media. This heat exchanger is described in detail below.

[0068] Figure 2 This is a structural diagram of a heat exchanger according to an embodiment of this application. Figure 2 As shown, the heat exchanger 100 may include a plurality of heat exchange sections 10, which are arranged along a first direction and spaced apart along the first direction. The plurality of heat exchange sections 10 are not interconnected. Each heat exchange section 10 extends along a second direction, and the heat exchange medium in at least two heat exchange sections 10 is different. The first direction is perpendicular to the second direction.

[0069] The heat exchange section 10 is a functional unit in the heat exchanger 100 that realizes heat exchange. It is a hollow structure that provides a flow channel for the heat exchange medium. The heat exchange section 10 can be tubular, plate-shaped, honeycomb-shaped, or other hollow shapes, and transfers heat to the surrounding medium through its walls.

[0070] The material of the heat exchange section 10 can be determined according to the properties of the heat exchange medium and the operating conditions. For example, when the heat exchange medium is a corrosive liquid, corrosion-resistant materials such as titanium alloy and polytetrafluoroethylene can be used; if it is used in a high-temperature and high-pressure steam environment, high-temperature resistant alloy steel is required.

[0071] In some embodiments, the heat exchanger 100 includes a plurality of heat exchange sections 10 extending along a second direction. The heat exchange sections 10 can be independent tubular, plate-shaped, or other hollow structures, and are not interconnected with each other, forming independent medium channels. The second direction is the main flow direction of the heat exchange medium.

[0072] In some embodiments, the heat exchange sections 10 are not interconnected because the heat exchange media inside the heat exchange sections 10 are not interconnected, or because the structures of the multiple heat exchange sections 10 are not in contact with each other.

[0073] In this embodiment of the application, the plurality of heat exchange sections 10 are two or more heat exchange sections 10.

[0074] The heat exchange section 10 extends along the second direction, allowing the medium to exchange heat with the surrounding environment or other media over a longer path, thus prolonging the heat exchange time and improving the adequacy of heat transfer. Taking a shell-and-tube heat exchanger as an example, the heat exchange tubes extend along the horizontal direction (the second direction), and the heat exchange medium inside the tubes continuously exchanges heat with the air and other media outside the tubes along the length of the tubes.

[0075] The extension length of the heat exchange section 10 can be determined based on heat exchange requirements, equipment space limitations, and fluid resistance, and this application does not impose any limitations. It should be noted that the extension length of the heat exchange section 10 must be within a reasonable size range. If the length is too long, although it can enhance the heat exchange effect, it will increase the fluid flow resistance and lead to increased energy consumption; if the length is too short, it will not be able to meet the heat exchange requirements.

[0076] In some embodiments, a plurality of heat exchange sections 10 are arranged along a first direction and spaced apart along the first direction. The spacing distance may be determined based on factors such as the flow rate and velocity of the medium, heat exchange requirements, and the structural strength of the equipment. It should be noted that the spacing distance of the heat exchange sections 10 should be within a reasonable size range. A larger spacing distance is beneficial for medium flow but will increase the volume of the heat exchanger 100; a smaller spacing distance can improve the compactness of the equipment but may lead to increased fluid resistance and affect the heat exchange effect.

[0077] The first direction is perpendicular to the second direction and is used to determine the spatial distribution of the multiple heat exchange units 10. In a two-dimensional plane, if the second direction is horizontal, then the first direction is vertical; in three-dimensional space, the first direction, the second direction, and a third direction perpendicular to both constitute a spatial coordinate system, which clarifies the arrangement of the heat exchange units 10.

[0078] Multiple heat exchange sections 10 spaced apart along a first direction create independent heat exchange spaces, ensuring that the heat exchange processes within each section 10 do not interfere with each other. This prevents temperature fields from interpenetrating between different heat exchange sections 10, and prevents heat from the high-temperature heat exchange section 10 from being directly transferred to the low-temperature heat exchange section 10 without effective utilization, which could lead to reduced heat exchange efficiency or deviations from expected heat exchange results. Since each heat exchange section 10 has an independent medium flow channel and heat exchange area, parameters such as heat exchange time and heat exchange rate for different media will not fluctuate due to the influence of adjacent heat exchange sections 10, ensuring that each heat exchange section 10 can operate stably according to predetermined process requirements.

[0079] For example, in a heat exchange scenario involving high-temperature steam and low-temperature coolant, the spaced heat exchange units 10 ensure that the steam condensation and coolant heating processes do not interfere with each other, thus guaranteeing both efficient steam condensation and the coolant achieving the predetermined temperature rise, thereby enabling efficient operation of the heat exchange process involving multiple media.

[0080] In some embodiments, at least two heat exchange sections 10 may contain different heat exchange media. These media include gaseous, liquid, and phase-change substances. Common media combinations include high-temperature steam and cooling water, heat transfer oil and air, and liquid refrigerants at different temperatures. For example, one heat exchange section 10 may contain high-temperature steam, while another may contain cooling water, or fluids at different temperatures and pressures.

[0081] In some embodiments, the heat exchange medium flowing through at least two heat exchange sections 10 being different includes the heat exchange medium being different in each of the plurality of heat exchange sections 10, or the heat exchange medium being different in two or more of the plurality of heat exchange sections 10.

[0082] In addition, for ease of description, the embodiments of this application define the reference based on the heat exchanger 100. The extension direction of the heat exchange section 10 is the X direction, i.e. the second direction, and the arrangement direction of the plurality of heat exchange sections 10 is the Y direction, i.e. the first direction. The direction perpendicular to the X direction and perpendicular to the Y direction is the Z direction, i.e. the third direction, wherein the X direction, the Y direction and the Z direction are perpendicular to each other.

[0083] In this embodiment, the heat exchanger 100 is achieved by arranging multiple non-interconnected heat exchange sections 10, each extending along a second direction and containing different heat exchange media, at intervals along a first direction. The independent heat exchange sections 10 eliminate cross-contact and mixing between different heat exchange media, avoiding the risk of chemical reactions, contamination, or performance failure due to differences in media properties. The spaced arrangement blocks heat conduction and convection interference between the heat exchange sections 10, preventing heat from the high-temperature heat exchange section 10 from diffusing to the low-temperature heat exchange section 10 without effective utilization. This allows each heat exchange section 10 to operate independently and stably based on its own media characteristics and process requirements. The heat exchange process is unaffected by changes in the temperature field and flow rate of adjacent heat exchange sections 10, improving the accuracy and reliability of multi-media parallel heat exchange.

[0084] Figure 3 This is another structural diagram of the heat exchanger according to an embodiment of this application. Figure 3 As shown, the heat exchanger 100 also includes a first manifold 20, which extends along a first direction and includes a plurality of non-interconnected first chambers 201. One end of the heat exchange section 10 is connected to the first chambers 201.

[0085] In this embodiment of the application, the first manifold 20 is a tubular structure extending along a first direction, which is consistent with the arrangement direction of the heat exchange section 10, and one end of the heat exchange section 10 is connected to the first manifold.

[0086] The interior of the first manifold 20 includes multiple non-interconnected first chambers 201; the number of first chambers 201 is equal to or greater than the number of heat exchange sections 10, and each first chamber 201 can correspond to one or a group of specific heat exchange media.

[0087] In some embodiments, the first chambers 201 may be of the same size and arranged along a first direction.

[0088] In some embodiments, two adjacent first chambers 201 can be completely sealed and isolated by a partition structure or a sealing element, so that different media do not cross-flow in the manifold. The partition material is selected according to the characteristics of the media. For example, the high-temperature medium chamber can use a high-temperature resistant alloy steel partition, and the corrosive medium chamber can use a titanium alloy or polytetrafluoroethylene partition.

[0089] For example, the edge of the baffle structure and the inner wall of the manifold can be sealed by welding. Furthermore, a high-temperature resistant or corrosion-resistant elastic sealing ring is embedded on the outside of the weld seam to further seal the baffle structure and the inner wall of the manifold, so that there is no leakage when pressure fluctuates or thermal expansion and contraction occurs.

[0090] In some embodiments, each first chamber 201 may be equipped with an independent heat exchange medium inlet and outlet for easy connection to external pipelines.

[0091] In some embodiments, one end of each heat exchange section 10, i.e., the inlet end or the outlet end, is connected to the corresponding first chamber 201 to realize the directional distribution or collection of the medium.

[0092] Optionally, the heat exchange medium can enter the heat exchange section 10 through the first chamber 201 and flow out from the other end of the heat exchange section 10; the heat exchange medium can also enter the heat exchange section 10 through the first chamber 201 and flow out from other structures of the first manifold 20.

[0093] In this embodiment, the heat exchanger 100 adds a first manifold 20 extending along a first direction and containing multiple non-interconnected first chambers 201. Each heat exchange section 10 is connected at one end to a specific chamber, achieving precise and independent distribution and collection of multiple media. The first chamber 201 is connected to one end of the heat exchange section 10, allowing for directional transport or output of the heat exchange medium and preventing distribution disorder. Its modular chamber design can employ standardized partitions and sealing structures, significantly simplifying the manufacturing process and reducing processing complexity and assembly difficulty through prefabrication and on-site assembly. Each chamber shares a common manifold shell, reducing the use of additional connectors and shell material compared to traditional single-medium independent pipes or complex compartmentalized structures.

[0094] Figure 4 This is another structural diagram of the heat exchanger according to an embodiment of this application. Figure 4As shown, the heat exchanger 100 also includes a second manifold 30, which extends along a first direction and includes a plurality of non-communicating second chambers 301; wherein, the first manifold 20 and the second manifold 30 are located on both sides of the heat exchange section 10 along the second direction, and the other end of the heat exchange section 10 is connected to the second chambers 301.

[0095] In some embodiments, the second manifold 30 is a tubular structure extending along a first direction, consistent with the arrangement direction of the heat exchange section 10, that is, parallel to the first manifold 20, and the interior of the second manifold 30 includes a plurality of non-communicating second chambers 301.

[0096] In some embodiments, the first chambers 201 may be of the same size and arranged along a first direction.

[0097] The second manifold 30 contains multiple non-interconnected second chambers 301. The number of second chambers 301 can be equal to or greater than the number of heat exchange sections 10.

[0098] Similar to the first chamber 201, the two adjacent second chambers 301 can be completely sealed and isolated by a partition structure or a sealing element, so that different media do not cross flow in the manifold. The partition material is selected according to the characteristics of the media.

[0099] In some embodiments, the first manifold 20 and the second manifold 30 are located at the two ends of the heat exchange section 10 along the second direction, namely the inlet end and the outlet end, forming a symmetrical structure. One end of the heat exchange section 10 is connected to the first chamber 201 of the first manifold 20, through which the heat exchange medium can be input, and the other end is connected to the second chamber 301 of the second manifold 30, through which the heat exchange medium can be output, thereby realizing the individual distribution and collection of each heat exchange medium.

[0100] In some embodiments, the number of second chambers 301 can be the same as the number of first chambers 201 in the first manifold 20, that is, the second chambers 301 correspond to the first chambers 201. Each second chamber 301 receives the same medium flowing from the corresponding first chamber 201 to the heat exchange section 10, thereby realizing independent closed-loop management of multiple media from input to output. Taking a heat exchange system containing three different media as an example, the three media flow into the corresponding heat exchange section 10 from the three first chambers 201 of the first manifold 20 for heat exchange, and after heat exchange, they flow out from the three corresponding second chambers 301 in the second manifold 30.

[0101] In this embodiment, a second manifold 30 is added opposite to the first manifold 20, realizing closed-loop independent management of multiple media input and output. Each medium flows into the heat exchange section 10 from the corresponding first chamber 201, and flows out from the matched second chamber 301 after heat exchange, completely avoiding cross-mixing. The symmetrical layout effectively balances the pressure on both sides of the heat exchange section 10, improving the stability of the heat exchanger 100. The first chamber 201 and the second chamber 301 have similar structures and unified processes, adopting standardized processing and modular design, and sharing molds to reduce customization costs. The dual manifolds form a symmetrical closed-loop structure of "input-output". The second chamber 301 corresponding to each first chamber 201 makes the path of each heat exchange medium from entry to exit clearly traceable, which can quickly confirm the flow direction of the heat exchange medium and avoid the risk of medium confusion in traditional complex pipelines.

[0102] Continue to refer to Figure 4 The heat exchange section 10 includes a plurality of heat exchange plates 101 spaced apart along a first direction. The plurality of heat exchange plates 101 are not interconnected. The heat exchange plates 101 extend along a second direction and are used to exchange heat with the heat exchange medium inside the heat exchange plate 101. One end of the heat exchange plate 101 is connected to the first chamber 201, and the other end of the heat exchange plate 101 is connected to the second chamber 301.

[0103] It should be understood that Figure 4 The area within the dashed box represents a heat exchange section 10, which includes multiple heat exchange plates 101.

[0104] In some embodiments, the heat exchange section 10 includes a plurality of heat exchange plates 101, that is, a heat exchange section 10 includes two or more heat exchange plates 101, the plurality of heat exchange plates 101 are arranged at intervals along a first direction, and a single heat exchange plate 101 extends along a second direction to form an independent heat exchange unit.

[0105] Adjacent heat exchange plates 101 are completely physically isolated from each other by a seal or a spacer structure, so that the heat exchange medium in the heat exchange plate 101 does not come into contact with other heat exchange plates 101; alternatively, they can be spaced out by welding to the first manifold 20 and the second manifold 30.

[0106] The heat exchange plate 101 has a plate-like structure. Multiple heat exchange plates 101 arranged along the first direction can be front-to-front facing each other, i.e., the side with larger heat exchange area, or side-to-side facing each other, i.e., the side with smaller heat exchange area.

[0107] In some embodiments, the heat exchange plate 101 includes heat exchange medium channels communicating with the first chamber 201 and the second chamber 301. The shape and number of channels can be customized according to the characteristics of the medium. For example, a wide shallow groove channel is used for high viscosity medium, and a corrugated turbulence channel is used for gas medium.

[0108] In some embodiments, one end of the heat exchange plate 101 is provided with a medium inlet communicating with the first chamber 201, and the other end is provided with an outlet communicating with the second chamber 301, forming a heat exchange path of "first chamber 201-heat exchange plate 101-second chamber 301".

[0109] In this embodiment, the heat exchanger 100 is designed with multiple heat exchange plates 101 spaced apart along a first direction and not interconnected, connected to the corresponding chambers of the first manifold 20 and the second manifold 30. The cooperation between the multiple heat exchange plates 101 and the manifold chambers achieves uniform distribution of the heat exchange medium: the first chamber 201 evenly distributes the heat exchange medium to the inlet of each heat exchange plate 101, and the flow rate of the heat exchange medium is consistent through multiple identical heat exchange plates 101; the second manifold 30 synchronously and evenly collects the heat exchange medium after heat exchange, avoiding uneven heat exchange caused by excessive or insufficient local flow.

[0110] Figure 5 This is another structural diagram of the heat exchanger according to an embodiment of this application. (In conjunction with...) Figure 4 and Figure 5 As shown, the first heat exchange unit among the plurality of heat exchange units 10 includes a first heat exchange plate group 1011 and a second heat exchange plate group 1012 arranged along a first direction. The first heat exchange plate group 1011 connects the first sub-chamber 2011 and the second chamber 301, and the second heat exchange plate group 1012 connects the second sub-chamber 2012 and the second chamber 301. The flow directions of the heat exchange medium in the first heat exchange plate group 1011 and the second heat exchange plate group 1012 are opposite. The first sub-chamber 2011 and the second sub-chamber 2012 are chambers in the first chamber 201 that are not connected to each other.

[0111] In some embodiments, the heat exchanger 100 includes a first heat exchange section, which includes a first heat exchange plate assembly 1011 and a second heat exchange plate assembly 1012 arranged along a first direction. The first chamber 201 is further divided into a first sub-chamber 2011 and a second sub-chamber 2012 that are not in communication with each other. The first sub-chamber 2011 and the second sub-chamber 2012 can be separated by a partition structure, a seal, etc. The first sub-chamber 2011 and the second sub-chamber 2012 can be arranged along the first direction or can be irregularly shaped. One end of the first heat exchange plate assembly 1011 is connected to the first sub-chamber 2011, and the other end is connected to the second chamber 301.

[0112] The flow directions of the heat exchange medium in the first heat exchange plate group 1011 and the second heat exchange plate group 1012 are opposite. Specifically, in the heat exchanger 100, the heat exchange medium first enters the first sub-chamber 2011 of the first chamber 201, is evenly distributed to the first heat exchange plate group 1011, and flows along the flow channel of the first heat exchange plate group 1011 to the second chamber 301 to complete the initial heat exchange; subsequently, the heat exchange medium merges in the second chamber 301 and enters the second heat exchange plate group 1012 in the opposite direction, flows in the opposite direction to the first heat exchange plate group 1011, enters the second sub-chamber 2012 through the flow channel of the second heat exchange plate group 1012, and finally flows out from the second sub-chamber 2012.

[0113] In this path, the heat exchange medium forms a counter-flow in the first heat exchange plate group 1011 and the second heat exchange plate group 1012, which maximizes the heat exchange temperature difference between the hot and cold media. At the same time, the physical isolation design of the first sub-chamber 2011 and the second sub-chamber 2012 ensures that there is no risk of mixing of the heat exchange medium throughout the process.

[0114] It should be understood that the first heat exchange section is one of the multiple heat exchange sections 10, or it can be a part of the multiple heat exchange sections 10, or it can be all of the multiple heat exchange sections 10.

[0115] In some embodiments, both the first heat exchange plate group 1011 and the second heat exchange plate group 1012 are composed of a plurality of heat exchange plates 101 arranged together. Similar to the heat exchange plates 101 described above, each heat exchange plate 101 may have various flow channel structures inside, such as corrugated, spiral, or straight grooves designed according to the characteristics of the medium, in order to enhance the turbulence of the medium within the plate and improve the heat exchange efficiency.

[0116] In this embodiment, the first chamber 201 is divided into a first sub-chamber 2011 and a second sub-chamber 2012. The heat exchange medium enters through the first sub-chamber 2011, flows sequentially through the first heat exchange plate group 1011, the second chamber 301, and the second heat exchange plate group 1012, and finally flows out from the second sub-chamber 2012. During this process, the medium flows in opposite directions within the two heat exchange plate groups, which improves the heat exchange temperature difference and heat transfer efficiency. The independent sub-chambers avoid the risk of medium mixing and improve the accuracy of heat exchange control.

[0117] In this embodiment, the first manifold 20 further includes a plurality of third chambers. The third chambers are not connected to the first chamber 201 and are adjacent to the first chamber 201. The second heat exchange section among the plurality of heat exchange sections 10 includes a first heat exchange channel, a second heat exchange channel and a third heat exchange channel. One end of the first heat exchange channel is connected to the first chamber 201, one end of the second heat exchange channel is connected to the third chamber, and the other end of the first heat exchange channel is connected to the other end of the second heat exchange channel through the third heat exchange channel. The third heat exchange channel and the first manifold 20 are arranged opposite to each other in the second direction.

[0118] In some embodiments, a plurality of third chambers are provided within the first manifold 20, adjacent to but not connected to the existing first chamber 201. For example, the first chamber 201 and the third chambers are arranged alternately along a first direction, that is, along the first direction, in the order of first chamber 201, third chamber, first chamber 201, third chamber. Alternatively, along the first direction, they can be arranged in the order of third chamber, first chamber 201, first chamber 201, third chamber.

[0119] The second heat exchange section connects the first chamber 201 and the third chamber. Specifically, the second heat exchange section includes a first heat exchange channel, a second heat exchange channel and a third heat exchange channel. One end of the first heat exchange channel is connected to the first chamber 201 and the other end intersects with the third heat exchange channel. One end of the second heat exchange channel is connected to the third chamber and the other end intersects with the third heat exchange channel, forming a "U-shaped" or "S-shaped" flow path.

[0120] It should be understood that the second heat exchange section is one of the multiple heat exchange sections 10, or it can be a part of the multiple heat exchange sections 10, or it can be all of the multiple heat exchange sections 10.

[0121] In some embodiments, the heat exchange section 10 can be a heat exchange plate, and the first heat exchange channel, the second heat exchange channel, and the third heat exchange channel are flow channels within the heat exchange plate, which are connected on the other side of the heat exchange section 10. The heat exchange section 10 can also be an integral part composed of multiple guide tubes, and the first heat exchange channel, the second heat exchange channel, and the third heat exchange channel are part of the guide tubes.

[0122] The flow direction of the heat exchange medium in the first heat exchange channel is opposite to that in the second heat exchange channel. Specifically, in the heat exchanger 100, the heat exchange medium first enters the first chamber 201, flows to the first heat exchange channel, completes the initial heat exchange along the first heat exchange channel, and then enters the second heat exchange channel in the opposite direction through the third heat exchange channel, flows in the opposite direction to the first heat exchange channel, enters the third chamber through the flow channel of the second heat exchange channel, and finally flows out from the third chamber.

[0123] In this embodiment, by setting up independent first chamber 201 and third chamber within the first manifold 20, the heat exchange medium enters the first chamber 201, flows through the heat exchange section 10 to the third chamber, and finally flows out from the second connection port 50. The unidirectional flow path, combined with the counter-current design of the heat exchange section 10, maximizes the temperature difference between the hot and cold media, enhancing heat transfer. The physical isolation between the chambers avoids the risk of media cross-flow and cross-contamination, and the independent chambers facilitate inspection and maintenance. Furthermore, this structure supports independent parallel heat exchange of multiple media, flexibly adapting to the heat exchange requirements under different operating conditions, combining high efficiency and practicality.

[0124] Figure 6This is another structural diagram of the heat exchanger according to an embodiment of this application. Figure 6 As shown, the heat exchanger 100 also includes a plurality of first connection ports 40 and a plurality of second connection ports 50. The first connection ports 40 are used to supply heat exchange medium to the heat exchange section 10, and the second connection ports 50 are used to output heat exchange medium. The number of first connection ports 40 is greater than or equal to the number of heat exchange sections 10, and the number of second connection ports 50 is greater than or equal to the number of heat exchange sections 10.

[0125] In some embodiments, the heat exchanger 100 includes a plurality of first connection ports 40 for supplying heat exchange media of a corresponding type to different heat exchange sections 10; the number of these ports is greater than or equal to the number of heat exchange sections 10. The heat exchanger 100 also includes a plurality of second connection ports 50 for discharging heat exchange media after heat exchange, the number of which is greater than or equal to the number of heat exchange sections 10.

[0126] In some embodiments, each type of heat exchanger 10 corresponds to at least one first connection port 40 and a second connection port 50; the connection port and the heat exchanger 10 can be connected one-to-one or one-to-many through components such as pipes and manifolds. For example, multiple heat exchangers 10 of the same medium type can share a first connection port 40, but need to be controlled by valve grouping.

[0127] In some embodiments, the first manifold 20 includes a plurality of non-communicating first chambers 201, and the second manifold 30 includes a plurality of non-communicating second chambers 301. One end of the heat exchange section 10 is connected to the first chamber 201, and the other end is connected to the second chamber 301. A first connection port 40 is connected to the first chamber 201, and a second connection port 50 is connected to the second chamber 301, so that the heat exchange medium enters the first chamber 201 through the first connection port 40, enters the second chamber 301 through the heat exchange section 10, and finally flows out from the second connection port 50.

[0128] Optionally, in the plurality of heat exchange units 10, the connection method of the connection ports may be that each first connection port 40 is connected to a first chamber 201 and each second connection port 50 is connected to the corresponding second chamber 301, or that some of the first connection ports 40 are connected to the first chamber 201 and other parts of the first connection ports 40 are connected to the second chamber 301.

[0129] In some embodiments, the first manifold 20 further includes a plurality of third chambers, with the first connection port 40 connected to the first chamber 201 and the second connection port 50 connected to the third chambers, so that the heat exchange medium enters the first chamber 201 through the first connection port 40, enters the third chamber through the heat exchange section 10, and finally flows out from the second connection port 50.

[0130] In some embodiments, the first chamber 201 further includes a first sub-chamber 2011 and a second sub-chamber 2012. A first connection port 40 connects to the first sub-chamber 2011, and a second connection port 50 connects to the second sub-chamber 2012, so that the heat exchange medium enters the first sub-chamber 2011 through the first connection port 40, enters the second chamber 301 through the first heat exchange plate group 1011, enters the second heat exchange plate group 1012 through the second chamber 301, enters the second sub-chamber 2012 from the second heat exchange plate group 1012, and finally flows out from the second connection port 50.

[0131] In this embodiment, by providing at least 10 types of first connection ports 40 and second connection ports 50 for each type of heat exchange medium, an independent transport channel is provided for each heat exchange medium, avoiding the risk of cross-contamination or mixing of different media due to shared interfaces. The redundant interface design supports flexible system expansion. When a new type of heat exchange medium is added, it can be directly connected to a backup interface without modifying the original pipeline, significantly shortening the system upgrade time. The clear correspondence not only reduces customization costs and installation difficulty but also facilitates quick location of faulty flow paths through interface identification, improving equipment maintenance efficiency.

[0132] In this embodiment of the application, each heat exchange plate 101 includes a plurality of partitions arranged at intervals along a third direction. The partitions extend along a second direction to divide the heat exchange plate 101 into a plurality of flow channels, and the plurality of flow channels are not interconnected. The third direction is the thickness direction of the heat exchange section 10, and the first direction, the second direction and the third direction are perpendicular to each other.

[0133] In some embodiments, a plurality of baffles are arranged at intervals along a third direction, and a single baffle extends along a second direction, that is, in the same direction as the extension of the heat exchange plate 101, dividing the internal space of the heat exchange plate 101 into a plurality of independent flow channels.

[0134] The third direction is the thickness direction of the heat exchange section 10. Multiple baffles are arranged at intervals along the thickness direction of the heat exchange section 10, that is, the front surfaces of the heat exchange plates 101 are arranged opposite each other.

[0135] In some embodiments, the baffle can be sealed to the upper and lower walls of the heat exchange plate 101 by welding or integral molding, so that adjacent flow channels are not interconnected. The number of flow channels can be adjusted according to the medium flow rate requirements. The cross-sectional shape of the flow channels can include rectangular, trapezoidal, semi-circular, etc., and can be set according to the characteristics of the heat exchange medium. For example, trapezoidal flow channels are used to enhance turbulence for gaseous media, while rectangular flow channels are used to reduce resistance for liquid media.

[0136] Each flow channel is connected at one end to the corresponding chamber of the first manifold 20 and at the other end to the second chamber 301 corresponding to the second manifold 30, forming an "input-heat exchange-output" path.

[0137] In some embodiments, the flow channels inside the heat exchange plate 101 can also be connected to form a loop, thereby increasing the flow distance of the heat exchange medium within the heat exchange plate 101 and increasing the heat exchange time.

[0138] In this embodiment, the heat exchange plate 101 of the heat exchanger 100 forms multiple independent and non-interconnected flow channels through multiple internal baffles arranged at intervals along a third direction and extending along a second direction, thereby improving heat exchange performance and management flexibility. The multiple flow channels achieve uniform distribution of the heat exchange medium, avoiding the uneven flow problem of traditional single flow channels, and ensuring full contact between the medium and the heat exchange plate 101, significantly enhancing the heat exchange effect.

[0139] In this embodiment of the application, the heat exchanger 100 further includes a heat dissipation structure, which is located between two adjacent heat exchange plates 101.

[0140] In some embodiments, the heat dissipation structure can be a heat-conducting heat dissipation layer, specifically, made of a high thermal conductivity material (such as copper foil, aluminum profile, graphene heat-conducting sheet), which is closely attached to the outer wall of the heat exchange plate 101 to quickly dissipate heat.

[0141] The heat dissipation structure can also be equipped with convection enhancement components. Specifically, fins, guide plates, and other structures can be selected to guide the cooling airflow or liquid flow through the heat dissipation gaps and enhance convective heat dissipation. When the heat dissipation structure is finned, it can fill the gap between adjacent heat exchange plates 101 to increase the heat exchange effect of the heat exchange plates 101.

[0142] In some embodiments, the heat dissipation structure can be fixed to the heat exchange plate 101 by welding, bolting, or adhesive bonding, so that the heat dissipation structure and the heat exchange plate 101 maintain good contact and improve the heat exchange effect.

[0143] In some embodiments, adjacent heat dissipation structures can be modularly spliced ​​to adapt to the combination requirements of different numbers of heat exchange plates 101.

[0144] In this embodiment, a heat dissipation structure is added between adjacent heat exchange plates 101 of the heat exchanger 100 to optimize the thermal management performance of the heat exchanger 100. The heat dissipation structure can quickly conduct heat from the heat exchange plates 101 through fins or high thermal conductivity materials, rapidly dissipating the heat to the outside and enhancing the heat dissipation efficiency of the heat exchange plates 101.

[0145] In this embodiment of the application, the heat exchanger 100 further includes a ventilation device, which is used to accelerate the cooling or heating of the heat exchange medium in the heat exchange section 10.

[0146] In some embodiments, when the heat exchange medium is a high-viscosity fluid or undergoing a phase change process, the natural convection heat transfer coefficient is low, resulting in slow cooling or heating rates. Furthermore, natural convection or simple pump-driven flow is easily affected by ambient temperature, leading to insufficient heat transfer stability. Therefore, additional equipment is needed to assist the heat exchange process of the heat exchange medium and enhance heat exchange.

[0147] In some embodiments, the heat exchanger 100 may further include at least one ventilation device, such as an axial flow fan, a centrifugal fan, an air pump, etc. The ventilation device introduces the airflow generated by the ventilation device into or around the heat exchange section 10 through structures such as air ducts and guide plates, so as to directly act on the heat exchange medium.

[0148] In some embodiments, the ventilation equipment can be linked with temperature sensors, flow controllers, etc., to automatically adjust the wind speed and air volume according to heat exchange requirements. The airflow generated by the ventilation equipment can form co-current, counter-current, or cross-current with the flow of the heat exchange medium, thereby enhancing heat exchange efficiency.

[0149] In some embodiments, ventilation equipment can also be installed according to the local temperature requirements of the heat exchange section 10, and can cool or heat the heat exchange medium in the local area of ​​the heat exchange section 10, so as to meet the independent temperature control requirements of multiple areas with large temperature differences.

[0150] In this embodiment, the ventilation equipment may be installed on the top, side or inside of the heat exchanger 100, and this application does not limit it.

[0151] Optionally, ventilation equipment can be installed on top of the heat exchanger 100, allowing airflow to convect with the medium within the heat exchange section 10 by vertically downward airflow. This installation method is suitable for scenarios where airflow tends to sink under gravity, effectively removing heat, such as in shell-and-tube heat exchangers 100 used for cooling high-temperature steam.

[0152] Optionally, ventilation equipment can be installed on the side of the heat exchanger 100 to achieve horizontal airflow, which is suitable for structures such as plate heat exchangers where the heat exchange sections 10 are arranged horizontally. Side airflow ensures that the airflow flows evenly through each heat exchange plate 101, enhancing the uniformity of heat exchange.

[0153] Alternatively, the ventilation equipment can be embedded inside the heat exchanger 100, making the ventilation equipment and heat exchanger 100 integrated, saving space and creating a more compact appearance. Embedded installation can be used for small heat exchangers 100 or integrated heat exchange systems where space is limited.

[0154] In this embodiment, the heat exchanger 100, by adding ventilation equipment and utilizing the connection and flow guidance design between the fan and the heat exchange section 10, achieves co-current, counter-current, or cross-current heat exchange between the airflow and the heat exchange medium. This effectively enhances the heat transfer between the media, significantly improves the heat exchange efficiency, and enables rapid cooling or heating of the medium. This expands the application scenarios of the heat exchanger 100 and improves its practicality and adaptability.

[0155] This application embodiment also provides a temperature control system, including a heat exchange device and a heat exchanger 100. The heat exchange device is used to exchange heat with a heat source or a cold source, and the heat exchanger 100 is used to heat or cool the heat exchange medium within the heat exchange device. The heat exchanger 100 includes a plurality of heat exchange sections 10, which are arranged along a first direction and spaced apart along the first direction. The plurality of heat exchange sections 10 are not interconnected, and each heat exchange section 10 extends along a second direction. At least two heat exchange sections 10 contain different heat exchange media.

[0156] In some embodiments, the heat source may be a battery device, an energy storage device, or an electric heating element, and the cold source may be a compression refrigeration system, a liquid cooling plate, or a phase change material, etc. The specific type needs to be determined according to the system application scenario and heat exchange requirements.

[0157] It should be understood that heat exchanger 100 may also include the heat exchanger 100 in any of the above embodiments.

[0158] This application embodiment also provides an energy storage device, including a battery device and a temperature control system, wherein the battery device is used to provide electrical energy. The temperature control system includes a heat exchange device and a heat exchanger 100, the heat exchanger 100 being used to heat or cool the heat exchange medium within the heat exchange device. The heat exchanger 100 includes a plurality of heat exchange sections 10, which are arranged along a first direction and spaced apart along the first direction. The plurality of heat exchange sections 10 are not interconnected, each heat exchange section 10 extending along a second direction, and at least two heat exchange sections 10 contain different heat exchange media.

[0159] It should be understood that heat exchanger 100 may also include the heat exchanger 100 in any of the above embodiments.

[0160] According to some embodiments of this application, see Figures 2 to 6 This application provides a heat exchanger 100, which includes a plurality of heat exchange sections 10. The plurality of heat exchange sections 10 are arranged along a first direction and spaced apart along the first direction. The plurality of heat exchange sections 10 are not interconnected. Each heat exchange section 10 extends along a second direction. At least two heat exchange sections 10 contain different heat exchange media. The first direction is perpendicular to the second direction.

[0161] The heat exchanger 100 further includes a first manifold 20 and a second manifold 30. The first manifold 20 extends along a first direction and includes a plurality of non-communicating first chambers 201. The second manifold 30 extends along the first direction and includes a plurality of non-communicating second chambers 301. The first manifold 20 and the second manifold 30 are located on opposite sides of the heat exchange section 10 along a second direction. One end of the heat exchange section 10 is connected to the first chamber 201, and the other end of the heat exchange section 10 is connected to the second chamber 301.

[0162] The heat exchange section 10 includes a plurality of heat exchange plates 101 spaced apart along a first direction. The plurality of heat exchange plates 101 are not interconnected. The heat exchange plates 101 extend along a second direction and are used to exchange heat with the heat exchange medium inside the heat exchange plate 101. One end of the heat exchange plate 101 is connected to the first chamber 201, and the other end of the heat exchange plate 101 is connected to the second chamber 301. The first heat exchange section among the multiple heat exchange sections 10 includes a first heat exchange plate group 1011 and a second heat exchange plate group 1012 arranged along a first direction. The first heat exchange plate group 1011 connects the first sub-chamber 2011 and the second chamber 301, and the second heat exchange plate group 1012 connects the second sub-chamber 2012 and the second chamber 301. The flow directions of the heat exchange medium in the first heat exchange plate group 1011 and the second heat exchange plate group 1012 are opposite.
