The heat exchanger assembly is hoisted as a whole into the inner container, and then the inner container is filled with the phase change material. During the actual hoisting and installation process, the heat exchanger assembly may be knocked, resulting in pipeline breakage and module failure. Summary of the Utility Model

Similarly, it can also play a limiting role during subsequent installation and transportation, keeping the gap between the heat exchange tube and the housing within a certain safe range. Even if there are unstable vibrations during installation or transportation, there will only be collisions between the limiting member and the housing, rather than collisions with the heat exchange tube, thus achieving the effect of protecting the heat exchange tube.

[0075] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0076] Currently, in a phase change heat storage device, since the heat storage capacity and heat exchange power of the phase change heat storage device are positively correlated with the mass of the phase change material and the size of the heat exchanger assembly, that is, the greater the heat storage capacity and heat exchange power, the more phase change material is required and the larger the heat exchanger assembly is.

[0077] When the heat exchanger assembly is large in volume and weight, it is mostly assembled by hoisting. The heat exchanger assembly is hoisted as a whole into the inner container, and then the inner container is filled with the phase change material. During the actual hoisting and installation process, the heat exchanger assembly may be knocked, resulting in problems such as pipeline fracture and module failure.

[0078] In the actual application process, in order to balance the heat storage utilization rate of the phase change material and the installation convenience of the heat exchanger assembly, it is necessary to control the gap between the heat exchanger assembly and the housing. If the installation gap is too large, the heat storage utilization rate of the material without the heat exchanger part is relatively low. If the installation gap is too small, when the heat exchanger assembly is hoisted into the inner container, the pipeline components are very likely to rub against the inner wall of the inner container, resulting in pipeline damage. At the same time, in addition to the heat exchanger body, the heat exchanger assembly also includes pipeline components, which are mainly composed of a manifold and connecting branch pipes. There are many pipelines. When the phase change heat storage device is in transportation, the pipeline components are very likely to move, be displaced, deformed, etc., and then lead to problems such as pipeline fracture and module failure.

[0079] Please refer to Figures 1 to 3 , in order to solve the above technical problems, the present application proposes a heat exchanger assembly 100. Among them, the heat exchanger assembly 100 includes: a housing 1 and a heat exchanger 2. The housing 1 forms an installation space 11. The housing 1 includes a top cover 12 and a bottom cover 13 that are connected to the installation space 11 and are oppositely arranged; the heat exchanger 2 is located in the installation space 11. The heat exchanger 2 includes a heat exchanger body 21 and two limiting members 22. The heat exchanger body 21 includes heat exchange tubes 211. The two limiting members 22 are respectively connected to opposite sides of the heat exchanger body 21 along the first direction X, and at least part of each limiting member 22 protrudes from the heat exchange tubes 211 along the first direction X. Part of each limiting member 22 protrudes from the heat exchanger body 21 along the second direction Y. The two limiting members 22 are both located at one end of the heat exchanger body 21 close to the bottom cover 13. The first direction X and the second direction Y are perpendicular.

[0080] Please continue to refer to Figures 1 to 3 , the heat exchanger assembly 100 based on the embodiment of the present application includes a housing 1 and a heat exchanger 2. Among them, the housing 1 forms an installation space 11 for accommodating the heat exchanger 2 and each component, and the housing 1 also has a top cover 12. During the actual installation process, the heat exchanger 2 enters the installation space 11 along the top cover 12 of the housing 1 by hoisting until the bottom of the heat exchanger 2 touches the bottom cover 13 of the housing 1, realizing the installation of the heat exchanger 2 and the housing 1.

[0081] The heat exchanger 2 includes a heat exchanger main body 21 and two limiting members 22. The heat exchanger main body 21 at least includes heat exchange tubes 211. The two limiting members 22 are respectively connected to the heat exchanger main body 21 along the first direction X, and the limiting members 22 protrude relative to the heat exchange tubes 211 along the first direction X. Each limiting member 22 is located between the heat exchange tubes 211 and the housing 1 in the first direction X, so that the heat exchange tubes 211 and the housing 1 are spaced apart in the first direction X, and the collision between the heat exchange tubes 211 and the housing 1 in the first direction X is minimized as much as possible.

[0082] To further ensure the limiting effect, a part of each limiting member 22 protrudes from the heat exchanger main body 21 along the second direction Y, so as to space the heat exchange tubes 211 and the housing 1 in the second direction Y, reduce the collision between the heat exchange tubes 211 and the housing 1 in the second direction Y, and play a protective effect on the heat exchanger main body 21 in all directions.

[0083] Moreover, each limiting member 22 is located at one end of the heat exchange tubes 211 close to the bottom cover 13, that is, the limiting member 22 is located at the bottom of the heat exchanger main body 21. During the actual installation process, since the heat exchanger 2 enters the housing 1 from the bottom, the limiting member 22 located at the bottom can play a limiting and isolating effect between the heat exchange tubes 211 and the housing 1 at the initial stage of installation. Similarly, it can also play a limiting role during subsequent installation and transportation processes, keeping the gap between the heat exchange tubes 211 and the housing 1 within a certain safe range. Even if there are unstable vibrations during installation or transportation, only the limiting member 22 collides with the housing 1, and the heat exchange tubes 211 will not be collided, thus playing a role in protecting the heat exchange tubes 211.

[0084] It can be understood that part of the heat exchanger 2 can be a finned tube heat exchanger 2. The side plates mentioned above can be part of the fin group or part of the isolation mesh frame, etc. The fin group has openings, and the heat exchange tubes 211 are passed through the openings. At least part of the fin group is located between the heat exchange tubes 211 and the housing 1, playing an isolation and limiting effect.

[0085] In some embodiments, the heat exchanger 2 further includes a plurality of sub-heat exchangers 2. Each sub-heat exchanger 2 is arranged in sequence along the second direction Y described above, and each sub-heat exchanger 2 is connected to the limiting member 22 to achieve the protective effect on the heat exchange tubes 211.

[0086] Please refer to Figures 4 to 9 , the limiting member 22 includes a limiting plate 221 and a connecting plate 222. The limiting plate 221 protrudes from the heat exchange tubes 211 along the first direction X. The limiting plate 221 is opposite to and spaced from the heat exchanger main body 21 along the first direction X. The connecting plate 222 connects the limiting plate 221 and the heat exchanger main body 21. Please refer to Figure 7, specifically, the limiting plate 221 is the part of the limiting member 22 that protrudes from the heat exchange tube 211 along the first direction X, and the limiting plate 221 is spaced apart from the heat exchanger main body 21, that is, there is a certain gap between the limiting plate 221 and the heat exchanger main body 21. Therefore, the limiting plate 221 can isolate the heat exchange tube 211 from the housing 1. The relative arrangement between the limiting plate 221 and the heat exchanger main body 21 indicates that at least part of the heat exchange plate is parallel to the heat exchanger main body 21, so as to ensure that when the limiting plate 221 is displaced due to a certain collision, it will not easily shift to the heat exchanger main body 21, thus achieving a better protection effect. The connecting plate 222 is used to connect to the heat exchanger main body 21, thereby achieving the fixing effect on the limiting plate 221.

[0087] It can be understood that in some other embodiments, one end of the limiting plate 221 away from the bottom of the heat exchanger 2 is inclined in the direction close to the housing 1. With such a setting, after the limiting plate 221 and the housing 1 collide and deform to a certain extent, the minimum gap between the limiting plate 221 and the heat exchange tube 211 can still be ensured to be within a certain range, which can effectively reduce the probability of collision between the limiting plate 221 and the heat exchange tube 211, thereby better protecting the heat exchange tube 211.

[0088] Further, please refer to Figure 5 , along the first direction X, the distance between the limiting plate 221 and the heat exchanger main body 21 is L1, and the heat exchanger assembly 100 satisfies: L1≥3mm. In the embodiment of the present application, L1 is the minimum distance between the limiting plate 221 and the heat exchanger main body 21. When the minimum distance is greater than or equal to 3mm, it can ensure that a gap with a distance of at least 3mm can be formed between the limiting plate 221 and the heat exchanger main body 21. When the limiting plate 221 collides with the housing 1, there can be a certain buffer gap, ensuring the safety of the heat exchange tube 211 during the installation process.

[0089] It can be understood that during the actual assembly process, it is also necessary to consider the deviation distance of the heat exchange tube 211 approaching the limiting plate 221 along the first direction X, the deviation distance of the limiting plate 221 approaching the heat exchange tube 211 along the first direction X, and the installation error distance of the limiting member 22 approaching the side wall of the housing 1 in the first direction X. Therefore, the actual distance L1 will be greater than or equal to 3mm to ensure a certain interval margin to cover the relevant error distances.

[0090] In addition, please refer to Figure 4 and Figure 5The connecting plate 222 includes a connecting bottom plate 2221 and a connecting side plate 2222. The connecting bottom plate 2221 is connected to an end of the limiting plate 221 close to the bottom cover 13 and extends in a direction close to the heat exchanger body 21; the connecting side plate 2222 is connected to an end of the connecting bottom plate 2221 away from the limiting plate 221 and extends in a direction away from the bottom cover 13, and the connecting side plate 2222 is connected to the heat exchanger body 21. It can be understood that the connecting bottom plate 2221 has an extension distance along the first direction X, which can be used to space the limiting plate 221 and the connecting side plate 2222, and the connecting side plate 2222 extends in a direction away from the bottom cover 13 and is connected to the heat exchanger body 21, thereby realizing the connection between the limiting member 22 and the heat exchanger body 21. With such a configuration, the structure of the connecting member is simple and easy to install and maintain.

[0091] In other embodiments, the connecting side plate 2222 extends along the second direction Y and has multiple installation positions. The heat exchanger body 21 also includes a side plate, and part of the heat exchange tube 211 protrudes from the side plate along the first direction X. The installation position of the connecting side plate 2222 corresponds to the side plate, and the assembly is performed avoiding the heat exchange tube 211, thereby realizing the connection and assembly of the connecting side plate 2222 and the heat exchanger body 21.

[0092] For the corresponding Figure 4 The connecting side plate 2222 is provided with a connecting hole 2222a extending along the first direction X. The connecting side plate 2222 is connected to the heat exchanger body 21 via a locking member passing through the connecting hole 2222a. The limiting plate 221 is provided with an avoidance hole 221a corresponding to the connecting hole 2222a. In order to facilitate the installation of the limit member 22 and the stability of its assembly, the locking member includes bolts and screws, etc. The connecting hole 2222a extends along the first direction X, and the limit plate 221 is correspondingly provided with an avoidance hole 221a extending along the first direction X. When the limit member 22 is actually assembled, the installation tool can extend from the avoidance hole 221a to the connecting hole 2222a to install or remove the locking member. With such a configuration, the locking member can be installed and removed from the side, so that the installation tool can avoid the heat exchange tube 211 for installation, which improves the loading and unloading speed while ensuring that the heat exchange tube 211 will not collide with the installation tool, thereby protecting the heat exchange tube 211.

[0093] In some embodiments, the limiting member 22 further includes a transition plate 223. The transition plate 223 connects the limiting plate 221 and the connecting plate 222, and the transition plate 223 is arranged at an obtuse angle relative to both the limiting plate 221 and the connecting plate 222. It can be understood that the transition plate 223 is connected to the connecting plate 222 at a certain obtuse angle, and the transition plate 223 extends in the direction close to the housing 1, thereby further increasing the distance between the limiting plate 221 and the heat exchange tube 211, reducing the probability of collision between the limiting plate 221 and the heat exchange tube 211. The transition plate 223 and the limiting plate 221 are connected at an obtuse angle, which ensures that the limiting plate 221 will not tilt in the direction close to the heat exchange tube 211.

[0094] Furthermore, the sum of the angles of the two obtuse angles should be greater than 270 degrees to ensure that the limiting plate 221 will not tilt in the direction close to the heat exchange tube 211, guarantee the distance between the limiting plate 221 and the heat exchange tube 211, and reduce the probability of collision between the limiting plate 221 and the heat exchange tube 211.

[0095] Please refer to Figures 7 to 8 , the limiting member 22 further includes two limiting side plates 224. Each limiting side plate 224 is connected to the connecting plate 222 and extends in the direction away from the bottom cover 13. Each limiting side plate 224 protrudes from the heat exchange tube 211 in the second direction Y. To ensure the limiting effect of the limiting member 22, the number of the limiting side plates 224 is two, and the two limiting side plates 224 are arranged oppositely in the second direction Y. Among them, the limiting side plate 224 protrudes from the heat exchange tube 211 in the second direction Y, which has the effect of spacing the heat exchange tube 211 and the housing 1 in the second direction Y. Combining with the limiting plate 221 spacing the heat exchange tube 211 and the housing 1 in the second direction Y, a better protection effect on the heat exchange tube 211 can be achieved.

[0096] Furthermore, the limiting side plate 224 has a first plate segment 2241 and a second plate segment 2242. The first plate segment 2241 connects the second plate segment 2242 and the connecting plate 222, and the first plate segment 2241 is arranged at an obtuse angle relative to both the second plate segment 2242 and the connecting plate 222. The first plate segment 2241 and the transition plate 223 have adjacent first side surfaces 2241a and second side surfaces 223a, and the distance between the first side surface 2241a and the second side surface 223a gradually increases in the direction away from the bottom cover 13. It can be understood that the first plate segment 2241 is connected to the connecting plate 222 at a certain obtuse angle, and the first plate segment 2241 extends in the direction close to the housing 1, thereby further increasing the distance between the second plate segment 2242 and the heat exchange tube 211, reducing the probability of collision between the limiting side plate 224 and the heat exchange tube 211. The first plate segment 2241 and the second plate segment 2242 are connected at an obtuse angle, which ensures that the limiting plate 221 will not tilt in the direction close to the heat exchange tube 211.

[0097] Among them, the sum of the angles of the two obtuse angles should be greater than 270 degrees to ensure that the second plate section 2242 does not tilt in the direction close to the heat exchange tube 211, ensure the distance between the second plate section 2242 and the heat exchange tube 211, and reduce the probability of collision between the limiting side plate 224 and the heat exchange tube 211.

[0098] In addition, specifically, reference can be made to Figure 9 , the first plate section 2241 has a first side surface 2241a, the transition plate 223 has a second side surface 223a, and the distance between the first side surface 2241a and the second side surface 223a increases in the direction away from the bottom cover 13 to form a tapered leading section of the transition plate 223 and the first plate section 2241. The tapered leading section can play a guiding role. When installing the heat exchanger 2, the tapered leading section first enters the housing 1. Since the size of the tapered leading section increases in the direction away from the bottom housing, the bottom end size of the heat exchanger 2 is smaller and can easily enter the interior of the housing 1. Therefore, the limiting member 22 in the present application can achieve the effect of limiting and blocking under the condition of facilitating the installation of the heat exchanger 2.

[0099] In order to ensure the structural strength of the limiting member 22, in the embodiment of the present utility model, the limiting member 22 is an integrally formed structure. The integrally formed structure can effectively reduce the problem of reduced structural strength caused by welding or other connection methods, so that there are no welds or other connection points between the various structures of the limiting member 22. Therefore, the overall strength of the limiting member 22 is ensured and it can withstand greater forces. And the integrally formed limiting member 22 can reduce the processes to improve production efficiency, reduce production costs, and ensure the consistency of multiple limiting members 22.

[0100] In some of the embodiments, please refer to Figure 6 , along the first direction X, the distance between the two mutually facing surfaces of the two limiting members 22 is L2, and along the first direction X, the distance between the two opposite inner wall surfaces of the installation space 11 is L3. The heat exchanger assembly 100 satisfies: L3 – L2 ≤ 2 mm. It can be understood that the distance L2 between the two mutually facing surfaces of the two limiting members 22 is fixed, and the distance L3 between the two opposite inner wall surfaces of the installation space 11 in the first direction X is also fixed. On the one hand, in order to save the phase change material and make the phase change material fully utilized, and on the other hand, to prevent the distance between the inner wall surface of the housing 1 and the heat exchanger 2 from being too large, the difference between L2 and L3 is limited within 2 mm, that is, the sum of the distances from the two limiting members 22 to the corresponding inner wall surfaces of the housing 1 should be less than or equal to 2 mm, thereby ensuring that the distance between the inner wall surface of the housing 1 and the heat exchanger 2 can be limited within a reasonable range.

[0101] The limiting member 22 can isolate the heat exchanger main body 21 from the inner wall of the housing 1, ensuring the protection effect on the heat exchange tubes 211. At the same time, it will not create an excessive distance, and the remaining volume of the installation space 11 of the housing 1 can also be fully utilized, enabling the amount of the phase change material filled therein to be maintained within a reasonable range and ensuring the utilization rate of the phase change material.

[0102] To further strengthen the connection effect between the heat exchanger 2 and the housing 1, the heat exchanger 2 further includes: a mounting assembly 23, which is located on the side of the heat exchanger 2 close to the top cover 12 and connects the housing 1 and the heat exchanger main body 21. Since the housing 1 has a top cover 12 and the mounting assembly 23 is located on the side of the heat exchanger main body 21 close to the top cover 12, it is convenient to install it from the top cover 12. Moreover, the mounting assembly 23 located at the top cover 12 can connect the housing 1 and the heat exchanger main body 21 to fix the two, so as to cooperate with the limiting member 22 located at the bottom to limit the position of the heat exchanger 2 in the housing 1 and prevent the heat exchanger assembly 100 from shaking during transportation or movement, playing a protective role for the heat exchanger 2.

[0103] Please refer to Figures 10 to 13 , the mounting assembly 23 includes: a first mounting member 231 and a second mounting member 232. The first mounting member 231 is mounted on the side of the heat exchanger main body 21 close to the top cover 12. The first mounting member 231 includes a first mounting plate 2311, and the first mounting plate 2311 is opposite to and spaced from the bottom cover 13; the second mounting member 232 is mounted on the housing 1. The second mounting member 232 includes a third mounting plate 2321, and the third mounting plate 2321 is stacked with the second mounting plate 2312, and the third mounting plate 2321 is connected to the first mounting plate 2311.

[0104] In the embodiment of the present application, the first mounting member 231 at least includes the first mounting plate 2311. Among them, the first mounting plate 2311 is opposite to the bottom cover 13. Since the top cover 12 and the bottom cover 13 are opposite, that is, the first mounting plate 2311 is opposite to the top cover 12, the plate surface of the first mounting plate 2311 faces the top cover 12. Correspondingly, the third mounting plate 2321 of the second mounting member 232 is stacked with the first mounting plate 2311 and the two are fixedly connected. With such a setting, on the one hand, it is convenient to directly fix and assemble the first mounting plate 2311 and the third mounting plate 2321 facing the top cover 12 from the top cover 12, with simple operation and improved installation efficiency. On the other hand, the first mounting member 231 connects the heat exchanger main body 21, the second mounting member 232 connects the housing 1, and the first mounting member 231 and the second mounting member 232 are cooperatively installed, so as to ensure that the heat exchanger main body 21 can be fixedly assembled with the housing 1, fix the position of the heat exchanger 2 in the housing 1 from the top cover 12, and ensure a strong constraint relationship between the two.

[0105] Specifically, the first mounting member 231 includes a first mounting plate 2311 and a second mounting plate 2312 connecting the first mounting plate 2311. The first mounting plate 2311 is connected to the housing 1, and the second mounting plate 2312 is connected to the heat exchanger body 21. At least one of the first mounting plate 2311 and the second mounting plate 2312 is provided with a through hole 2313 for the header pipe 2122 of the heat exchanger 2 to pass through. At this time, the first mounting plate 2311 may include a portion (corresponding to the horizontal plate) opposite to and spaced from the bottom cover 13, and a portion (corresponding to the vertical plate) stacked with the second mounting plate 2312. Among them, the through hole 2313 for the header pipe 2122 of the heat exchanger 2 to pass through may be provided on the vertical plate.

[0106] It can be understood that the heat exchange tubes 211 are pipeline components inside the heat exchanger body 21, and the heat exchange tubes 211 include an energy charging pipeline and an energy discharging pipeline. Among them, the energy charging pipeline is communicated with the external heat source end, and the energy discharging pipeline is communicated with the domestic water end. The heat exchange tubes 211 are communicated with the header pipe 2122 through the connecting pipes 2123. The main function of the header pipe 2122 is to distribute and aggregate the water circuits of the above-mentioned energy charging pipeline and energy discharging pipeline, and an inlet header pipe 2122, an outlet header pipe 2122, a supply header pipe 2122, and a discharge header pipe 2122 are provided corresponding to the above-mentioned energy charging pipeline and energy discharging pipeline. And the water is distributed from the header pipe 2122 to the connecting pipes 2123. The function of the connecting pipe 2123 is to transfer the water in the header pipe 2122 to the heat exchanger body 21, and the heat exchanger body 21 charges and discharges heat to the phase change material.

[0107] In the embodiment of the present application, the first mounting member 231 is connected to one end of the heat exchanger body 21 close to the top cover 12, which is the end where the header pipe 2122 is located. In order to reduce the probability of interference and collision between the first mounting member 231 and the inner wall surface of the housing 1, a part of the first mounting member 231 is inclined along the part close to the header pipe 2122. Correspondingly, in order to form an avoidance of the header pipe 2122, at least one of the first mounting plate 2311 and the second mounting plate 2312 of the first mounting member 231 is provided with a through hole 2313 for the header pipe 2122 to pass through. That is to say, the through hole 2313 may be provided on the first mounting plate 2311, or may be provided on the second mounting plate 2312, or semi-circular grooves are respectively provided at the connection between the first mounting plate 2311 and the second mounting plate 2312, and the through hole 2313 is formed by splicing at the first mounting plate 2311 and the second mounting plate 2312. With such a setting, the size of the corresponding cut hole can be determined according to the pipe diameter of the header pipe 2122, and it can be better fitted and installed with the header pipe 2122, so as to have a better supporting effect on the header pipe 2122.

[0108] Furthermore, a sealing ring 2314 is provided between the manifold 2122 and the inner wall surface of the through hole 2313. The sealing ring 2314 is located between the first mounting member 231 and the manifold 2122, which can effectively reduce the friction of the first mounting member 231 on the manifold 2122. During actual transportation, collisions and vibrations are inevitable. The sealing ring 2314 can absorb these collisions and vibrations, providing a protective effect on the manifold 2122.

[0109] Correspondingly, to ensure the fixing effect, the heat exchanger assembly 100 includes two mounting assemblies 23. The two mounting assemblies 23 are respectively arranged corresponding to both sides of the heat exchanger 2 along the second direction Y, and respectively connect both sides of the heat exchanger body 21 along the second direction Y to the housing 1. The two mounting assemblies 23 are oppositely arranged along the second direction Y, and each mounting assembly 23 is used to correspond to both sides of each heat exchanger body 21 along the second direction Y, so as to increase the installation and fixing points of the heat exchanger body 21 in the second direction Y, fix the heat exchanger body 21 on both sides along the second direction Y, so as to achieve a better locking effect on the heat exchanger 2, and can effectively reduce the problem of damage to the heat exchanger 2 caused by vibrations and collisions during transportation and installation.

[0110] In the embodiment of the present application, the number of heat exchanger bodies 21 is multiple, and the multiple heat exchanger bodies 21 are spaced along the second direction Y. The multiple heat exchanger bodies 21 are linked, which can increase the overall heat exchange area of the heat exchanger 2, thereby improving the heat exchange efficiency of the entire system. It can also enhance the stability of the system. Even if a small part of the heat exchanger bodies 21 in the heat exchanger 2 fails, heat exchange work can still be carried out to ensure the stable operation of the system.

[0111] In some of the above embodiments, the limiting member 22 extends along the second direction Y. Therefore, in this embodiment, the limiting member 22 can simultaneously space multiple heat exchanger bodies 21 and the housing 1, so as to provide a protective effect on the multiple heat exchanger bodies 21 and ensure the normal operation of the heat exchanger 2.

[0112] In addition, please refer to Figure 14 , the heat exchanger 2 further includes a gap maintaining structure 24. The gap maintaining structure 24 extends along the second direction Y and is fixedly connected to the multiple heat exchanger bodies 21. In the present application, the gap maintaining structure 24 is used to connect and fix the multiple heat exchanger bodies 21 and maintain the gap between the multiple heat exchanger bodies 21, so that the gap between each heat exchanger body 21 is appropriate, ensuring that the phase change material can flow smoothly between the multiple heat exchanger bodies 21. While improving the heat exchange efficiency, it also helps to prevent contact and vibration between the heat exchanger bodies 21, thereby improving the stability and heat exchange efficiency of the heat exchanger 2.

[0113] In some of these embodiments, the gap-holding structure 24 includes: two top connectors 241 and two bottom connectors 242. The top connectors 241 are connected to the tops of the plurality of heat exchanger bodies 21, and the top connectors 241 are arranged oppositely along the first direction X; the two bottom connectors 242 are connected to the bottoms of the plurality of heat exchanger bodies 21, and the bottom connectors 242 are arranged oppositely along the first direction X. It can be understood that the top of the heat exchanger body 21 is the end of the heat exchanger body 21 close to the top cover 12. Relatively, the bottom of the heat exchanger body 21 is the end of the heat exchanger body 21 close to the bottom cover 13. Among them, the two top connectors 241 and the two bottom connectors 242 are respectively used to maintain the gaps at the top and bottom of the heat exchanger body 21, prevent the heat exchanger bodies 21 from contacting each other, and maintain an appropriate gap. By connecting to the tops of the plurality of heat exchanger bodies 21, the top connectors 241 help to enhance the structural stability of the entire heat exchanger assembly 100, reduce displacement caused by vibration or external forces. The same applies to the bottom connectors 242, and the bottom connectors 242 can provide additional support for the connection at the bottom of the heat exchanger body 21 to ensure the stability of the heat exchanger body 21 under gravity and other loads. It can be understood that the top connectors 241 and the bottom connectors 242 together enhance the structural integrity of the entire heat exchanger assembly 100, enabling it to remain stable under various operating conditions.

[0114] Furthermore, please refer to Figure 15 and Figure 16 , the top connector 241 includes a first connecting top plate 2411 and a second connecting top plate 2412. The first connecting top plate 2411 includes a main plate 2411a extending along the second direction Y and a plurality of mounting side plates 2411b extending along the third direction Z and spaced along the second direction Y. Each mounting side plate 2411b is connected to the opposite sides of the heat exchanger body 21 along the first direction X; the second connecting top plate 2412, the second connecting top plate 2412 extends in a direction away from the mounting side plates 2411b. The second connecting top plate 2412 is connected to the main plate 2411a. The second connecting top plate 2412 is provided with a hoisting hole position 2412a along the second direction Y; the third direction Z, the first direction X, and the second direction Y are perpendicular to each other in pairs.

[0115] Specifically, the first connecting top plate 2411 includes a main plate 2411a and mounting side plates 2411b. Among them, the main plate 2411a is connected to the tops of the plurality of heat exchanger bodies 21, and the mounting side plates 2411b correspond to the number of the heat exchanger bodies 21 and are connected to the opposite sides of each heat exchanger body 21 along the first direction X. It can be understood that the main plate 2411a plays a role in fixing the tops of the respective heat exchanger bodies 21, while the mounting side plates 2411b fix the sides, further ensuring the fixing and spacing effects of the top connector 241 and strengthening the structural strength of the heat exchanger 2.

[0116] In addition, in the present application, the second connecting member extends away from the mounting side plate 2411b and is provided with a hoisting hole 2412a, which facilitates the installation of the heat exchanger 2 into the housing 1 by connecting the hoisting hole 2412a during the installation process of the heat exchanger 2. Further, the number of hoisting holes 2412a on the second connecting top plate 2412 can be multiple, thereby increasing the hoisting points and facilitating the stability during hoisting, ensuring the safety during the installation process of the heat exchanger assembly 100.

[0117] Please refer to Figure 3 and Figure 17 , the heat exchanger assembly 100 further includes a pipeline structure 212, and the pipeline structure 212 includes: a plurality of main pipes 2121, a plurality of manifold pipes 2122, and a plurality of connecting pipes 2123. Each main pipe 2121 is close to the top cover 12, the manifold pipes 2122 communicate with each main pipe 2121, each manifold pipe 2122 is located on one side of the heat exchange pipes 211 along the direction close to the top cover 12, at least a part of each connecting pipe 2123 extends along the third direction Z, one end of each connecting pipe 2123 communicates with the manifold pipe 2122, and the other end of each connecting pipe 2123 communicates with the heat exchange pipe 211; the third direction Z, the first direction X, and the second direction Y are perpendicular to each other in pairs. Specifically, since the number of heat exchanger bodies 21 in the present application is multiple, in order to facilitate the uniform distribution of fluid to each heat exchanger body 21, the main pipes 2121, the manifold pipes 2122, and the connecting pipes 2123 are used for flow splitting to ensure that each heat exchanger 2 can achieve the best effect.

[0118] Among them, the main pipe 2121 is used for the overall distribution or collection of fluid, and the manifold pipe 2122 is used for further distributing or collecting the fluid in the connecting pipes 2123 corresponding to each heat exchanger body 21, so as to ensure that the fluid can be evenly distributed among the heat exchanger bodies 21, ensure that the fluid in each heat exchanger body 21 can be evenly heated and flow smoothly, thereby improving the heat exchange efficiency, and the design of the pipeline structure 212 is clear, ensuring the clarity of the fluid flow path and facilitating subsequent maintenance and repair.

[0119] In addition, the pipeline structure 212 further includes a plurality of multi-way joints 2124, and each multi-way joint 2124 includes: a main body; and at least three ports, each port is provided on the main body, one of the ports communicates with the connecting pipe 2123, and the remaining ports are respectively connected to the heat exchange pipes 211 of each heat exchanger body 21. The design of the multi-way joint 2124 can further simplify the flow path design, avoid excessive number of connecting pipes 2123, and facilitate subsequent maintenance and repair.

[0120] It can be understood that since some of the multi-way connectors 2124 are close to the bottom of the heat exchanger 2, the multi-way connectors 2124 are located on one side of the heat exchanger body 21 along the first direction X, and at least part of the limiting member 22 protrudes along the first direction X from the multi-way connectors 2124, thereby protecting the multi-way connectors 2124 and preventing the multi-way connectors 2124 from colliding with the inner wall of the housing 1, ensuring the safety and stability of the heat exchanger assembly 100 during actual installation and transportation.

[0121] The multi-way connector 2124 includes a tee joint. In some embodiments, a single heat exchanger body 21 has two groups of heat exchange tubes 211 spaced along the second direction Y. One end of the tee joint communicates with the connecting pipe 2123, and the two sub-ends respectively communicate with the two groups of heat exchange tubes 211, so as to achieve the effect of flow splitting, and the structure is simple and clear. Correspondingly, multiple groups of heat exchange tubes 211 can also be arranged at intervals along the second direction Y in a single heat exchanger body 21, and the number of sub-ends of the multi-way connector 2124 can be increased accordingly. In this case, the multi-way connector 2124 can also be a flute tube. The present application does not limit this here, as long as the relevant functions can be completed.

[0122] Furthermore, the pipeline structure 212 is any one of a copper pipe, a copper alloy pipe, an aluminum pipe, an aluminum alloy pipe, and a stainless steel pipe; the heat exchange tube 211 is any one of a copper pipe, a copper alloy pipe, an aluminum pipe, an aluminum alloy pipe, and a stainless steel pipe. In the embodiments of the present application, copper pipes and copper alloy pipes generally have good heat conduction performance and corrosion resistance, and are suitable for application scenarios requiring high heat exchange efficiency; aluminum pipes and aluminum alloy pipes are light in weight, have good heat conduction performance, and low cost, and can be applied to application scenarios where weight reduction is required. And stainless steel pipes have excellent corrosion resistance and high strength, and are suitable for application scenarios with high requirements for corrosion resistance. By selecting appropriate pipe materials, the requirements of different application scenarios can be met.

[0123] In a second aspect, please refer to Figures 18 to 22 , an embodiment of the present application provides a phase change heat storage device 1000, and the phase change heat storage device 1000 includes the above-mentioned heat exchanger assembly 100. The phase change heat storage device 1000 includes the above-mentioned heat exchanger assembly 100. The specific structure of the heat exchanger assembly 100 refers to the above embodiments. Since the phase change heat storage device 1000 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0124] Please refer to Figures 20 to 22, the phase change heat storage device 1000 further includes: a phase change heat storage material 200, a housing 300, and a heat insulation layer 400. The housing 300 is sleeved outside the heat exchanger assembly 100. The heat insulation layer 400 is located between the housing 1 and the housing 300. The heat insulation layer 400 includes a first heat insulation layer 410 and a second heat insulation layer 420. The first heat insulation layer 410 is closer to the housing 1 than the second heat insulation layer 420, and the hardness of the first heat insulation layer 410 is lower than that of the second heat insulation layer 420. It should be noted that the phase change heat storage material 200 is used to store or release heat. The phase change heat storage material 200 is filled in the housing 300 to ensure the basic heat exchange function of the phase change heat storage device 1000. The heat insulation layer 400 is used to reduce the heat dissipation from the heat exchanger assembly 100 to the outside and improve the energy utilization efficiency.

[0125] Please refer to Figure 19 , the housing 300 further includes an outer side plate 310, an outer top plate 320, and an outer bottom plate 330. Among them, a plurality of pipe passing openings 311 and wire passing openings 312 are correspondingly arranged at the outer side plate 310. The pipe passing openings 311 are used for the plurality of main pipes 2121 to pass through, and the wire passing openings 312 are used for the wires inside the heat exchanger 2 to pass through, and can play a certain role in organizing the wires. In addition, a hem is provided at the edge of the outer side plate 310. In the embodiment of the present application, the number of the outer side plates 310 is multiple, and the hems of the respective outer side plates 310 are connected in sequence. The housing 300 is further provided with an outer support foot 340, and the outer support foot 340 is connected to the outer bottom plate 330 and is used to support the outer bottom plate 330.

[0126] Among them, reference can be made to Figure 21 , the heat insulation layer 400 is further subdivided into a first heat insulation layer 410 and a second heat insulation layer 420. The first heat insulation layer 410 is close to the housing 1 and is softer than the second heat insulation layer 420. Therefore, the first heat insulation layer 410 can better adapt to the shape of the housing 1 and has a better protection effect on the housing 1, playing a role of buffering and protecting between the second heat insulation layer 420 and the housing 1. The second heat insulation layer 420 has a higher hardness, better structural stability and durability, and further improves the heat insulation effect.

[0127] Specifically, the first heat insulation layer 410 includes at least one of a sponge layer and a rubber layer; and / or, the second heat insulation layer 420 includes at least one of a vacuum insulation panel and a polyurethane panel. The first heat insulation layer 410 adopts a sponge layer or a rubber layer. These materials are soft and have a certain elasticity, which helps to adapt to the shape of the housing 1 and slight displacements, and plays a protective effect on the housing 1. The second heat insulation layer 420 adopts a vacuum insulation panel or a polyurethane panel. These materials have good heat insulation performance and relatively high hardness, and can provide better structural stability and durability.

[0128] The phase change heat storage device 1000 further includes a fin group. The fin group includes a plurality of sheet-shaped fins. The fins have openings for pipes to pass through. Among them, the fins include aluminum sheets. It can be understood that the fins increase the surface area of the heat exchanger body 21, which helps to improve the heat exchange efficiency. By increasing the number and surface area of the fins, the thermal resistance can be reduced, making it easier for heat to transfer from the phase change heat storage material 200 to the external environment. Moreover, the aluminum sheets have good thermal conductivity, which helps to accelerate the heat transfer. With such a setting, the phase change heat storage device 1000 can not only effectively store and release heat, but also reduce heat loss and improve the energy utilization efficiency. The fin group can further improve the heat exchange efficiency.

[0129] In a third aspect, an embodiment of the present application provides a heating, ventilation and air conditioning (HVAC) system. The HVAC system includes the above-mentioned phase change heat storage device 1000. The specific structure of the phase change heat storage device 1000 refers to the above embodiment. Since the HVAC system adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
