DETAILED DESCRIPTION

[0076] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0077] At present, in the phase change heat storage device, 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, i.e., the greater the heat storage capacity and heat exchange power, the more phase change material is needed, and the larger the heat exchanger assembly.

[0078] When the heat exchanger assembly is large in size and weight, it is usually assembled by hoisting, that is, the heat exchanger assembly is hoisted into the inner container as a whole, and then the inner container is filled with phase change material. In the actual hoisting and installation process, the heat exchanger assembly may be bumped, resulting in pipe rupture and module failure.

[0079] In actual application, in order to balance the heat storage utilization rate of the phase change material and the installation convenience of the heat exchanger assembly, the gap between the heat exchanger assembly and the shell needs to be controlled. If the installation gap is too large, the heat storage utilization rate of the material without the heat exchanger is low. If the installation gap is too small, when the heat exchanger assembly is hoisted into the inner container, the pipe components are prone to scratch the inner container wall, resulting in pipe damage. At the same time, in addition to the heat exchanger body, the heat exchanger assembly also includes pipe components, which are mainly composed of a header and connecting branch pipes. When the phase change heat storage device is transported, the pipe components are prone to move, dislocate, deform and other problems, which may further cause pipe rupture and module failure.

[0080] Please refer to FIGS. 1-3. To solve the above technical problems, the present application provides a heat exchanger assembly 100, wherein the heat exchanger assembly 100 includes a shell 1 and a heat exchanger 2. The shell 1 forms an installation space 11, and includes a top cover 12 and a bottom cover 13 connected to the installation space 11 and arranged opposite to each other. The heat exchanger 2 is located in the installation space 11, and includes a heat exchanger body 21 and two limit pieces 22. The heat exchanger body 21 includes heat exchange pipes 211. The two limit pieces 22 are respectively connected to the two opposite sides of the heat exchanger body 21 along a first direction X, and at least part of each limit piece 22 protrudes from the heat exchange pipes 211 along the first direction X. Part of each limit piece 22 protrudes from the heat exchanger body 21 along a second direction Y. The two limit pieces 22 are 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.

[0081] Please continue to refer to FIGS. 1-3. The heat exchanger assembly 100 according to the embodiment of the present application includes a shell 1 and a heat exchanger 2. The shell 1 forms an installation space 11 for accommodating the heat exchanger 2 and various components. The shell 1 also has a top cover 12. In the actual installation process, the heat exchanger 2 is hoisted along the top cover 12 of the shell 1 into the installation space 11 until the bottom of the heat exchanger 2 contacts the bottom cover 13 of the shell 1, thereby achieving the installation of the heat exchanger 2 and the shell 1.

[0082] The heat exchanger 2 comprises a heat exchanger body 21 and two limiting members 22. The heat exchanger body 21 comprises at least heat exchange pipes 211. The two limiting members 22 are connected to the heat exchanger body 21 along the first direction X and protrude from the heat exchanger body 21 along the first direction X. Each limiting member 22 is located between the heat exchange pipes 211 and the shell 1 along the first direction X, so as to separate the heat exchange pipes 211 and the shell 1 along the first direction X and reduce the collision between the heat exchange pipes 211 and the shell 1 along the first direction X.

[0083] In order to further ensure the limiting effect, part of each limiting member 22 protrudes from the heat exchanger body 21 along the second direction Y, so as to separate the heat exchange pipes 211 and the shell 1 along the second direction Y and reduce the collision between the heat exchange pipes 211 and the shell 1 along the second direction Y, thereby protecting the heat exchanger body 21 in each direction.

[0084] In addition, each limiting member 22 is located at one end of the heat exchange pipes 211 close to the bottom cover 13, i.e., the limiting member 22 is located at the bottom of the heat exchanger body 21. In the actual installation process, since the heat exchanger 2 enters the shell 1 from the bottom, the limiting member 22 at the bottom can limit and separate the heat exchange pipes 211 and the shell 1 at the beginning of installation. Similarly, the limiting member 22 can also play a limiting role in the subsequent installation and transportation process, so as to keep the gap between the heat exchange pipes 211 and the shell 1 within a certain safety range. Even if there is unstable shaking during installation or transportation, only the limiting member 22 and the shell 1 collide, and the heat exchange pipes 211 are not collided, thereby protecting the heat exchange pipes 211.

[0085] It can be understood that part of the heat exchanger 2 can be a tube-fin heat exchanger 2. The side plate mentioned above can be part of a fin group or part of a separation net frame, etc. The fin group has an opening, the heat exchange pipes 211 are arranged in the opening, and at least part of the fin group is located between the heat exchange pipes 211 and the shell 1, thereby playing a separation and limiting effect.

[0086] In some embodiments, the heat exchanger 2 further comprises a plurality of sub-heat exchangers 2. Each sub-heat exchanger 2 is arranged along the second direction Y mentioned above. Each sub-heat exchanger 2 is connected to the limiting member 22, so as to achieve the protection effect of the heat exchange pipes 211.

[0087] Please refer to FIG. 4 to FIG. 9, the limiting member 22 includes a limiting plate 221 and a connecting plate 222, the limiting plate 221 protrudes from the heat exchange pipe 211 along the first direction X, the limiting plate 221 is opposite to the heat exchanger body 21 and is spaced apart along the first direction X, and the connecting plate 222 connects the limiting plate 221 and the heat exchanger body 21. Please refer to FIG. 7, specifically, the limiting plate 221 is the part of the limiting member 22 that protrudes from the heat exchange pipe 211 along the first direction X, and the limiting plate 221 is spaced apart from the heat exchanger body 21, that is, there is a certain gap between the limiting plate 221 and the heat exchanger body 21, so that the limiting plate 221 can isolate the heat exchange pipe 211 from the shell 1. The relative arrangement between the limiting plate 221 and the heat exchanger body 21 indicates that at least part of the heat exchange plate and the heat exchanger body 21 are arranged in parallel, so as to ensure that the limiting plate 221 will not easily deviate to the heat exchanger body 21 when it is displaced due to a certain collision, thereby achieving better protection effect. The connecting plate 222 is used to connect the heat exchanger body 21, thereby achieving the fixing effect of the limiting plate 221.

[0088] It can be understood that in 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 shell 1. In this way, after the limiting plate 221 collides with the shell 1 and deforms to a certain extent, the minimum gap between the limiting plate 221 and the heat exchange pipe 211 can still be guaranteed within a certain range, which can effectively reduce the probability of collision between the limiting plate 221 and the heat exchange pipe 211, thereby better protecting the heat exchange pipe 211.

[0089] Further, please refer to FIG. 5, the distance between the limiting plate 221 and the heat exchanger body 21 along the first direction X is L1, and the heat exchanger assembly 100 satisfies: L1≥3mm. In the embodiments of the present application, L1 is the minimum distance between the limiting plate 221 and the heat exchanger body 21. When the minimum distance is greater than or equal to 3mm, a gap with a distance of at least 3mm can be formed between the limiting plate 221 and the heat exchanger body 21, so that when the limiting plate 221 collides with the shell 1, there is a certain buffer gap, thereby ensuring the safety of the heat exchange pipe 211 during installation.

[0090] It can be understood that in the actual assembly process, the deviation distance of the heat exchange pipe 211 along the first direction X close to the limiting plate 221, the deviation distance of the limiting plate 221 along the first direction X close to the heat exchange pipe 211, and the installation error distance of the limiting member 22 along the first direction X close to the side wall of the shell 1 also need to be considered. Therefore, the actual distance L1 will be greater than or equal to 3mm, so as to ensure a certain interval allowance to cover the related error distances.

[0091] In addition, referring to FIGS. 4 and 5, the connecting plate 222 includes a connecting bottom plate 2221 and a connecting side plate 2222, the connecting bottom plate 2221 is connected to one end of the limiting plate 221 close to the bottom cover 13 and extends towards the heat exchanger main body 21, the connecting side plate 2222 is connected to the other end of the connecting bottom plate 2221 away from the limiting plate 221 and extends away from the bottom cover 13, and the connecting side plate 2222 is connected to the heat exchanger main body 21. It can be understood that the connecting bottom plate 2221 has an extension distance along the first direction X and can be used to separate the limiting plate 221 and the connecting side plate 2222, the connecting side plate 2222 extends away from the bottom cover 13 and is connected to the heat exchanger main body 21, thereby realizing the connection between the limiting member 22 and the heat exchanger main body 21. In this way, the connecting member has a simple structure and is easy to install and maintain.

[0092] In other embodiments, the connecting side plate 2222 extends along the second direction Y and has a plurality of mounting positions, and the heat exchanger main body 21 further includes a side plate, part of the heat exchange pipes 211 protrude from the side plate along the first direction X, the mounting positions of the connecting side plate 2222 correspond to the side plate and avoid the heat exchange pipes 211 to be assembled, thereby realizing the connection and assembly of the connecting side plate 2222 and the heat exchanger main body 21.

[0093] Correspondingly, referring to FIG. 4, the connecting side plate 2222 is provided with a connecting hole 2222a extending along the first direction X, the connecting side plate 2222 and the heat exchanger main body 21 are connected through a locking member arranged in the connecting hole 2222a, and the limiting plate 221 is provided with an avoiding hole 221a corresponding to the connecting hole 2222a. In order to facilitate the installation of the limiting member 22 and the stability of the assembly, the locking member includes a bolt, a screw or the like, the connecting hole 2222a extends along the first direction X, the limiting plate 221 is provided with an avoiding hole 221a extending along the first direction X, in actual assembly of the limiting member 22, the installation tool can be inserted into the connecting hole 2222a from the avoiding hole 221a to install or disassemble the locking member. In this way, the installation and disassembly of the locking member can be realized from the side, the installation tool can avoid the heat exchange pipes 211 to be installed, the speed of installation and disassembly is improved, the heat exchange pipes 211 are not bumped by the installation tool, and the heat exchange pipes 211 are protected.

[0094] In some embodiments, the limiting member 22 further comprises a transition plate 223 connecting the limiting plate 221 and the connecting plate 222, and the transition plate 223 is arranged at an obtuse angle with respect to the limiting plate 221 and the connecting plate 222. It can be understood that the transition plate 223 is connected at an obtuse angle with the connecting plate 222, and the transition plate 223 extends in a direction close to the shell 1, thereby further increasing the distance between the limiting plate 221 and the heat exchange pipe 211, reducing the probability of collision between the limiting plate 221 and the heat exchange pipe 211, and the obtuse angle connection between the transition plate 223 and the limiting plate 221 ensures that the limiting plate 221 will not tilt in the direction close to the heat exchange pipe 211.

[0095] Further, the sum of the angles of the two obtuse angles is greater than 270 degrees, so as to ensure that the limiting plate 221 will not tilt in the direction close to the heat exchange pipe 211, and to ensure the distance between the limiting plate 221 and the heat exchange pipe 211, thereby reducing the probability of collision between the limiting plate 221 and the heat exchange pipe 211.

[0096] Please refer to FIGS. 7-8, the limiting member 22 further comprises two limiting side plates 224, each of which is connected to the connecting plate 222 and extends away from the bottom cover 13, and each of which protrudes from the heat exchange pipe 211 in the second direction Y. In order to ensure the limiting effect of the limiting member 22, the number of limiting side plates 224 is two, and the two limiting side plates 224 are oppositely arranged in the second direction Y, wherein the limiting side plate 224 protrudes from the heat exchange pipe 211 in the second direction Y, thereby spacing the heat exchange pipe 211 and the shell 1 in the second direction Y, and in combination with the limiting plate 221 spacing the heat exchange pipe 211 and the shell 1 in the second direction Y, a better protection effect of the heat exchange pipe 211 can be achieved.

[0097] Further, 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 with respect to the second plate segment 2242 and the connecting plate 222, and the first plate segment 2241 and the transition plate 223 have adjacent first and second side surfaces 2241a and 223a, and the distance between the first and second side surfaces 2241a and 223a gradually increases in a direction away from the bottom cover 13. It can be understood that the first plate segment 2241 is connected at an obtuse angle with respect to the connecting plate 222, and the first plate segment 2241 extends in a direction close to the shell 1, thereby further increasing the distance between the second plate segment 2242 and the heat exchange pipe 211, reducing the probability of collision between the limiting side plate 224 and the heat exchange pipe 211, and the obtuse angle connection between the first plate segment 2241 and the second plate segment 2242 ensures that the limiting plate 221 will not tilt in the direction close to the heat exchange pipe 211.

[0098] The sum of the two obtuse angles is greater than 270 degrees to ensure that the second plate segment 2242 cannot be tilted in a direction close to the heat exchange pipe 211, to ensure the distance between the second plate segment 2242 and the heat exchange pipe 211, and to reduce the probability of collision between the limiting side plate 224 and the heat exchange pipe 211.

[0099] In addition, as shown in FIG. 9, the first plate segment 2241 has a first side surface 2241a, and the transition plate 223 has a second side surface 223a. The distance between the first side surface 2241a and the second side surface 223a increases in a direction away from the bottom cover 13, to form a tapered guide section of the transition plate 223 and the first plate segment 2241. The tapered guide section can have a guiding effect. When the heat exchanger 2 is installed, the tapered guide section enters the shell 1 first. Since the size of the tapered guide section increases in a direction away from the bottom shell, the bottom end of the heat exchanger 2 has a smaller size, which can facilitate the entry of the heat exchanger 2 into the shell 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.

[0100] In order to ensure the structural strength of the limiting member 22, in the embodiment of the present application, 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 is no welding seam or other connection point between the structures of the limiting member 22, thereby ensuring the overall strength of the limiting member 22 and enabling it to withstand greater force. In addition, the integrally formed limiting member 22 can reduce the process, thereby improving production efficiency, reducing production cost, and ensuring the consistency of multiple limiting members 22.

[0101] In some embodiments, as shown in FIG. 6, along the first direction X, the distance between the two surfaces of the two limiting members 22 facing away from each other 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≤2mm. It can be understood that the distance L2 between the two surfaces of the two limiting members 22 facing away from each other 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 phase change material and make full use of the phase change material, on the other hand, in order to prevent the distance between the inner wall surface of the shell 1 and the heat exchanger 2 from being too large, the difference between L2 and L3 is limited to within 2mm, that is, the distance between the two limiting members 22 and the corresponding inner wall surface of the shell 1 is less than or equal to 2mm, thereby ensuring that the distance between the inner wall surface of the shell 1 and the heat exchanger 2 can be limited within a reasonable range.

[0102] The limiting piece 22 can isolate the heat exchanger main body 21 and the inner wall of the shell 1, so as to ensure the protection effect on the heat exchange pipe 211, and meanwhile, the remaining volume of the installation space 11 of the shell 1 can also be fully utilized, so that the amount of the phase change material filled therein can be kept within a reasonable range, and the utilization rate of the phase change material is ensured.

[0103] In order to further strengthen the connection effect between the heat exchanger 2 and the shell 1, the heat exchanger 2 further comprises: an installation assembly 23 located on the side of the heat exchanger 2 close to the top cover 12 and connected with the shell 1 and the heat exchanger main body 21. Since the shell 1 has the top cover 12, and the installation 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 the installation assembly 23 from the top cover 12, and the installation assembly 23 located at the top cover 12 can be connected with the shell 1 and the heat exchanger main body 21 to fix them, so as to cooperate with the limiting piece 22 at the bottom to limit the position of the heat exchanger 2 in the shell 1, prevent the heat exchanger assembly 100 from shaking during transportation or movement, and protect the heat exchanger 2.

[0104] Please refer to FIGS. 10 to 13, the installation assembly 23 comprises: a first installation piece 231 and a second installation piece 232, the first installation piece 231 is installed on the side of the heat exchanger main body 21 close to the top cover 12, and the first installation piece 231 comprises a first installation plate 2311, the first installation plate 2311 is oppositely arranged with the bottom cover 13; the second installation piece 232 is installed on the shell 1, and the second installation piece 232 comprises a third installation plate 2321, the third installation plate 2321 is stacked with the second installation plate 2312, and the third installation plate 2321 is connected with the first installation plate 2311.

[0105] In the embodiment of the present application, the first installation piece 231 at least comprises the first installation plate 2311, wherein the first installation 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 installation plate 2311 is opposite to the top cover 12, the board surface of the first installation plate 2311 faces the top cover 12, the third installation plate 2321 of the second installation piece 232 corresponding to the first installation plate 2311 is stacked with the first installation plate 2311, and the two are fixedly connected, in this way, on the one hand, the first installation plate 2311 and the third installation plate 2321 facing the top cover 12 can be directly fixed and assembled from the top cover 12, which is simple in operation and improves the installation efficiency, on the other hand, the first installation piece 231 is connected with the heat exchanger main body 21, the second installation piece 232 is connected with the shell 1, the first installation piece 231 and the second installation piece 232 are cooperatively installed, so as to ensure that the heat exchanger main body 21 can be fixedly assembled with the shell 1, the position of the heat exchanger 2 in the shell 1 is fixed from the top cover 12, and the strong constraint relationship between the two is ensured.

[0106] Specifically, the first mounting member 231 includes a first mounting plate 2311 connected to the shell 1 and a second mounting plate 2312 connected to the heat exchanger body 21, and at least one of the first mounting plate 2311 and the second mounting plate 2312 is provided with a through hole 2313 through which the header pipe 2122 of the heat exchanger 2 passes. At this time, the first mounting plate 2311 can include a portion (corresponding to a horizontal plate) opposite and spaced apart from the bottom cover 13 and a portion (corresponding to a vertical plate) stacked with the second mounting plate 2312, wherein the vertical plate can be provided with a through hole 2313 through which the header pipe 2122 of the heat exchanger 2 passes.

[0107] It can be understood that the heat exchange pipe 211 is a pipe component inside the heat exchanger body 21, and the heat exchange pipe 211 includes a charging pipe and a discharging pipe. The charging pipe is in communication with the heat source end of the outside, and the discharging pipe is in communication with the domestic water end. The heat exchange pipe 211 is in communication with the header pipe 2122 through the connecting pipe 2123. The main function of the header pipe 2122 is to distribute and collect the water paths of the charging pipe and the discharging pipe, and the charging pipe and the discharging pipe are provided with charging header pipes 2122, discharging header pipes 2122, and discharging header pipes 2122. The water is distributed to the connecting pipe 2123 by the header pipe 2122. 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.

[0108] In the embodiment of the present application, the first mounting member 231 is connected to the heat exchanger body 21 near one end of the top cover 12, located at one end of the header pipe 2122. In order to reduce the probability of interference and collision between the first mounting member 231 and the inner wall surface of the shell 1, part of the first mounting member 231 near the header pipe 2122 is inclined. Correspondingly, in order to form an avoidance for 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 through which the header pipe 2122 passes. That is, the through hole 2313 can be provided on the first mounting plate 2311, or on the second mounting plate 2312, or a semicircular groove is respectively provided at the connection of the first mounting plate 2311 and the second mounting plate 2312, and the through hole 2313 is formed by splicing the first mounting plate 2311 and the second mounting plate 2312. In this way, the size of the through hole can be determined according to the pipe diameter of the header pipe 2122, which can better fit the header pipe 2122 for installation, thereby providing better support for the header pipe 2122.

[0109] Further, the sealing ring 2314 is arranged between the inner wall surface of the manifold 2122 and the via 2313, and is located between the first mounting member 231 and the manifold 2122, so as to effectively reduce the friction of the first mounting member 231 on the manifold 2122. In the actual transportation process, some collisions and vibrations are inevitable, and the sealing ring 2314 can absorb these collisions and vibrations, thereby protecting the manifold 2122.

[0110] Correspondingly, in order to ensure the fixing effect, the heat exchanger assembly 100 comprises two mounting assemblies 23, which are respectively arranged on both sides of the heat exchanger 2 along the second direction Y, and are respectively connected with the shell 1 along both sides of the heat exchanger body 21 along the second direction Y. The two mounting assemblies 23 are oppositely arranged along the second direction Y, and each mounting assembly 23 is arranged on both sides of each heat exchanger body 21 along the second direction Y, so as to increase the mounting and fixing points of the heat exchanger body 21 along the second direction Y, and fix the heat exchanger body 21 along both sides of the second direction Y, thereby achieving better locking effect of the heat exchanger 2, and effectively reducing the damage of vibration and collision to the heat exchanger 2 in the transportation and installation process.

[0111] 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, so as to increase the heat exchange area of the heat exchanger 2 as a whole, thereby improving the heat exchange efficiency of the whole system. In addition, the stability of the system is also enhanced, that is, even if a small part of the heat exchanger bodies 21 in the heat exchanger 2 fails, the heat exchange work can still be carried out, so as to ensure the stable operation of the system.

[0112] In some embodiments described above, the limiting member 22 extends along the second direction Y, so in the present embodiment, the limiting member 22 can simultaneously space the multiple heat exchanger bodies 21 and the shell 1, thereby achieving the protection effect of the multiple heat exchanger bodies 21, and ensuring the normal operation of the heat exchanger 2.

[0113] In addition, referring to FIG. 14, the heat exchanger 2 further comprises a gap maintaining structure 24, which extends along the second direction Y and is fixedly connected with 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, the phase change material can flow smoothly between the multiple heat exchanger bodies 21, the heat exchange efficiency is improved, and the contact and vibration between the heat exchanger bodies 21 are prevented, thereby improving the stability and heat exchange efficiency of the heat exchanger 2.

[0114] In some embodiments, the gap maintaining structure 24 comprises two top connectors 241 and two bottom connectors 242, the top connectors 241 are connected to the top of the plurality of heat exchanger bodies 21, each of the top connectors 241 is oppositely arranged along the first direction X; the bottom connectors 242 are connected to the bottom of the plurality of heat exchanger bodies 21, each of the bottom connectors 242 is oppositely arranged 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, and correspondingly, the bottom of the heat exchanger body 21 is the end of the heat exchanger body 21 close to the bottom cover 13, wherein the two top connectors 241 and the two bottom connectors 242 are respectively used to maintain the gap at the top and the bottom of the heat exchanger body 21, prevent the heat exchanger bodies 21 from contacting each other, and maintain a proper gap. By connecting with the top of the plurality of heat exchanger bodies 21, the top connector 241 helps to enhance the structural stability of the entire heat exchanger assembly 100, reduce displacement caused by vibration or external force, and the bottom connector 242 is the same, and the bottom connector 242 can provide additional support for the connection of the bottom of the heat exchanger body 21, ensure the stability of the heat exchanger body 21 under the gravity and other loads. It can be understood that the top connector 241 and the bottom connector 242 together enhance the structural integrity of the entire heat exchanger assembly 100, so that it can maintain stability under various operating conditions.

[0115] Further, referring to FIGS. 15 and 16, the top connector 241 comprises a first connecting top plate 2411 and a second connecting top plate 2412, the first connecting top plate 2411 comprises a main plate 2411a extending along the second direction Y and a plurality of mounting edge plates 2411b extending along the third direction Z and spaced apart along the second direction Y, each of the mounting edge plates 2411b connects the opposite sides of the heat exchanger body 21 along the first direction X; the second connecting top plate 2412 extends in a direction away from the mounting edge plate 2411b, the second connecting top plate 2412 is connected with the main plate 2411a, and the second connecting top plate 2412 is provided with a lifting hole 2412a along the second direction Y; the third direction Z, the first direction X and the second direction Y are perpendicular to each other.

It can be understood that the main plate 2411a has a fixing effect on the top of each heat exchanger body 21, and the mounting edge plate 2411b fixes the side surface, further ensuring the fixing and spacing effect of the top connector 241, and strengthening the structural strength of the heat exchanger 2.

[0117] Further, in the present application, the second connecting piece extends away from the mounting side plate 2411b and is provided with a lifting hole position 2412a, so as to facilitate installation of the heat exchanger 2 into the shell 1 by connecting the lifting hole position 2412a during the installation process of the heat exchanger 2. Further, the number of lifting hole positions 2412a on the second connecting top plate 2412 can be multiple, so as to increase the lifting point position and facilitate the stability during lifting, thereby ensuring the safety during the installation process of the heat exchanger assembly 100.

Specifically, since the number of heat exchanger bodies 21 is multiple in the present application, in order to facilitate uniform distribution of fluid to each heat exchanger body 21, the fluid is distributed by the main pipe 2121, the manifold pipe 2122 and the connecting pipe 2123, so as to ensure that each heat exchanger 2 can play the best effect.

[0119] Among them, the main pipe 2121 is used for total distribution or collection of fluid, the manifold pipe 2122 is used for further distribution or collection of fluid in the connecting pipe 2123 corresponding to each heat exchanger body 21, so as to ensure that the fluid can be uniformly distributed between the heat exchanger bodies 21, and ensure that the fluid in each heat exchanger body 21 can be uniformly heated and smoothly flow, thereby improving the heat exchange efficiency, and the design of the pipeline structure 212 is clear, which ensures the clarity of the fluid flow path, and facilitates subsequent maintenance and maintenance.

[0120] In addition, the pipeline structure 212 further comprises a plurality of multi-way joints 2124, each multi-way joint 2124 comprises: a main body 21241; and at least three ports 21242, each port 21242 is arranged at the main body 21241, one of the ports 21242 is communicated with the connecting pipe 2123, and the remaining ports 21242 are respectively connected to the heat exchange pipes 211 of each heat exchanger body 21.

[0121] It can be understood that, since part of the multi-port connector 2124 is close to the bottom of the heat exchanger 2, the multi-port connector 2124 is 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 from the multi-port connector 2124 along the first direction X, thereby protecting the multi-port connector 2124 and avoiding collision between the multi-port connector 2124 and the inner wall of the shell 1, and ensuring the safety and stability of the heat exchanger assembly 100 during actual installation and transportation.

[0122] The multi-port connector 2124 includes a tee connector. In some embodiments, a single heat exchanger body 21 has two groups of heat exchange pipes 211 spaced along the second direction Y, one end of the tee connector is in communication with the connecting pipe 2123, and the two sub-ends are in communication with the two groups of heat exchange pipes 211, respectively, thereby achieving the effect of flow splitting and having a simple and clear structure. Correspondingly, a plurality of groups of heat exchange pipes 211 can also be spaced along the second direction Y in a single heat exchanger body 21, and the number of sub-ends of the multi-port connector 2124 is correspondingly increased. In this case, the multi-port connector 2124 can also be a flute-shaped pipe. The present application does not limit this, as long as the relevant functions can be completed.

[0124] In a second aspect, referring to FIGS. 18-22, the present application provides a phase change heat storage device 1000, which comprises the heat exchanger assembly 100 described above. The heat exchanger assembly 100 comprises the heat exchanger assembly 100 described above. The specific structure of the heat exchanger assembly 100 is referred 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 effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0125] Please refer to FIGS. 20-22, the phase change heat storage device 1000 further comprises: a phase change heat storage material 200, an outer shell 300, and an insulation layer 400. The outer shell 300 is sleeved to the heat exchanger assembly 100, and the insulation layer 400 is located between the shell 1 and the outer shell 300. The insulation layer 400 comprises a first insulation layer 410 and a second insulation layer 420. The first insulation layer 410 is closer to the shell 1 than the second insulation layer 420, and the hardness of the first insulation layer 410 is lower than that of the second 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 outer shell 300, which is used to ensure the basic heat exchange function of the phase change heat storage device 1000. The insulation layer 400 is used to reduce the heat loss from the heat exchanger assembly 100 to the outside, thereby improving the energy utilization efficiency.

[0126] Please refer to FIG. 19, the outer shell 300 further comprises an outer side plate 310, an outer top plate 320, and an outer bottom plate 330. A plurality of pipe passing openings 311 and wire passing openings 312 are provided on the outer side plate 310. The pipe passing openings 311 are used to pass the plurality of main pipes 2121, and the wire passing openings 312 are used to pass the wires inside the heat exchanger 2, which can also have the effect of arranging the wires. In addition, the edges of the outer side plate 310 are provided with folded edges.

The outer shell 300 is further provided with an outer support leg 340, which is connected with the outer bottom plate 330 and used to support the outer bottom plate 330.

[0127] As shown in FIG. 21, the insulation layer 400 is further divided into a first insulation layer 410 and a second insulation layer 420. The first insulation layer 410 is close to the shell 1 and softer than the second insulation layer 420. Therefore, the first insulation layer 410 can better adapt to the shape of the shell 1 and has a better protection effect on the shell 1. The second insulation layer 420 has a higher hardness and better structural stability and durability, and further improves the insulation effect.

[0128] Specifically, the first insulation layer 410 comprises at least one of a sponge layer and a rubber layer; and / or the second insulation layer 420 comprises at least one of a vacuum insulation panel and a polyurethane panel. The first 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 and slight displacement of the shell 1, thereby achieving the protection effect on the shell 1. The second insulation layer 420 adopts a vacuum insulation panel or a polyurethane panel. These materials have good heat insulation performance and high hardness, which can provide better structural stability and durability.

[0129] The phase change heat storage device 1000 further comprises a fin group, the fin group comprising a plurality of fin-shaped fins, the fins having an opening for the pipe to pass through; wherein the fins comprise aluminum fins. 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, and heat can be more easily transferred from the phase change heat storage material 200 to the external environment. Moreover, the aluminum fins have good heat conduction performance, which helps to speed up the heat transfer. In this way, the phase change heat storage device 1000 can not only effectively store and release heat, but also reduce heat loss and improve energy utilization efficiency. The fin group can further improve the heat exchange efficiency.
