Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a heat exchange module and a HVAC system. Background Art

[0002] In HVAC systems, phase change heat storage technology is widely used due to its efficient energy storage and release characteristics. The tube-fin heat exchanger uses the characteristics of phase change materials that absorb or release a large amount of heat when the physical state changes at a specific temperature. Fins are installed on the outside of the heat exchange tubes, and phase change materials are filled between the heat exchange tubes and the fins. The fins effectively increase the heat exchange area, achieving efficient energy storage and release.

[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0081] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0082] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0083] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0084] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0085] Fin-and-tube heat exchangers usually install fins on the surface of the heat exchange tubes to increase the heat exchange area to improve the heat exchange efficiency. In the related technology, the shapes of the fins are diverse, and the arrangement direction is closely related to the layout of the heat exchange tubes. According to the shape of the fins, they can be divided into square fins, circular fins, spiral fins, longitudinal fins, corrugated fins, spiral serrated fins, needle fins, etc. These fins are arranged around the heat exchange tubes in a multi-directional and multi-level manner. The combination of fins and heat exchange tubes leads to the design of the internal structure of the fin-and-tube heat exchanger is often more complicated. The complex internal structure will not only limit the fluidity of the phase change material during the filling process, but also increase the difficulty of gas discharge, resulting in uneven filling of the phase change material and low filling efficiency.

[0086] Based on the above problems, an embodiment of the present application provides a heat exchange module and a HVAC system. Each heat exchange unit of the heat exchange structure is provided with a plurality of fins arranged at intervals along the second horizontal direction, and the plurality of fins extend along the vertical direction. Compared with a horizontal or complexly arranged fin structure, the vertically extending fins reduce the resistance to the flow of the phase change material, and are not prone to accumulation and retention of the phase change material. A heat conduction space extending along the vertical direction is formed between two adjacent fins. The vertically extending heat conduction space allows the phase change material to flow naturally under the action of gravity during the filling process, so that the phase change material can be filled in the heat conduction space more smoothly, thereby improving the filling speed.

[0087] Based on the structure and arrangement of the fins in the embodiment of the present application, during the filling process, the air and residual gas in the heat exchange unit will be squeezed by the phase change material and pushed to the top of the heat transfer space. Since the fins and the heat transfer space extend vertically, the phase change material can expel the gas during the flow process, effectively reducing the generation of bubbles, so that the heat exchange tubes and fins can be fully immersed in the phase change material, reducing the retention of bubbles, improving the uniformity of the phase change material filling, and ensuring the high purity and density of the phase change material during the filling process.

[0088] See also Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the structure of a heat exchange module 1 according to an embodiment of the present application. Figure 2 This is a schematic cross-sectional view of a heat exchange module 1 along AA according to an embodiment of the present application. The heat exchange module 1 includes a heat exchange shell 10, a heat exchange structure 20 and a phase change material 30. The heat exchange shell 10 has a heat exchange space 110 inside. The heat exchange space 110 is used to provide an accommodation space for the heat exchange structure 20 and the phase change material 30. The heat exchange structure 20 is at least partially disposed in the heat exchange space 110. The phase change material 30 is filled in the heat exchange shell 10 and at least partially submerges the heat exchange structure 20. Heat exchange is performed between multiple heat exchange units 21 in the heat exchange structure 20 and the phase change material 30, so that the phase change material 30 undergoes a phase change and realizes phase change heat storage or phase change heat release.

[0089] See also Figure 3-Figure 5 , Figure 3 is a schematic structural diagram of a heat exchange structure 20 according to an embodiment of the present application, Figure 4 is a schematic structural diagram of multiple heat exchange units 21 in an embodiment of the present application, Figure 5 for Figure 4 , the heat exchange structure 20 includes a plurality of heat exchange units 21, and the plurality of heat exchange units 21 are arranged along the first horizontal direction X. Each heat exchange unit 21 includes a plurality of heat exchange tubes 211 and a heat conducting part connected to the plurality of heat exchange tubes 211. The heat exchange tube 211 is the main heat exchange element in the heat exchange structure 20. The heat exchange medium in the heat exchange tube 211 and the phase change material 30 outside the heat exchange tube 211 perform heat exchange through the tube wall and the heat conducting part. The heat conducting part includes a plurality of fins 212. The plurality of fins 212 increase the heat exchange area to improve the heat exchange efficiency.

[0090] In the embodiment of the present application, a plurality of fins 212 are arranged at intervals along the second horizontal direction Y, the second horizontal direction Y is perpendicular to the first horizontal direction X, and each fin 212 extends along the vertical direction Z. The fins 212 extending along the vertical direction Z not only increase the contact area between the phase change material 30 and the heat exchange unit 21, but also promote the rapid transfer of heat. Compared with the fins arranged in multiple directions and multiple levels and the fins arranged horizontally, the fins 212 arranged along the vertical direction Z have a small flow resistance to the phase change material 30, and are not easy to form the accumulation and retention of the phase change material 30. A heat conduction space 210 extending along the vertical direction Z is formed between two adjacent fins 212, and the heat conduction space 210 is filled with the phase change material 30. During the filling process, the phase change material 30 flows from top to bottom along the fins 212 under the action of gravity to smoothly fill each heat conduction space 210, which helps to increase the filling speed. Furthermore, during the filling process, the air and residual gas in the heat exchange unit 21 will be squeezed by the phase change material 30 and pushed to the top of the heat conduction space 210. Since the fins 212 and the heat conduction space 210 extend vertically, the phase change material 30 can expel the gas during the flow process, effectively reducing the generation of bubbles, so that the heat exchange tubes 211 and the fins 212 can be fully immersed in the phase change material, reducing the retention of bubbles, avoiding the reduction of heat conduction efficiency due to bubble retention, and improving the uniformity of the filling of the phase change material 30, which helps to improve the consistency of the heat exchange performance in the heat exchange unit 21.

[0091] The heat exchange housing 10 also has a filling inlet, which is connected to the heat exchange space 110, and the phase change material 30 enters the heat exchange space 110 through the filling inlet. In the vertical direction Z, the filling inlet is located above the heat exchange unit 21. In this way, the filling direction is consistent with the direction in which the phase change material 30 naturally extends in the heat exchange space 110, and the phase change material 30 can flow into and fill the entire heat exchange space 110 more smoothly, which helps to reduce the resistance and blockage that may occur during the filling process, thereby improving the filling efficiency.

[0092] Continue reading Figure 3-Figure 5 In one embodiment of the present application, a plurality of heat exchange units 21 of the heat exchange structure 20 are sequentially spaced along the first horizontal direction X, and a gap space 200 is formed between two adjacent heat exchange units 21, and the gap space 200 extends along the second horizontal direction Y. Each heat exchange unit 21 has a plurality of heat conduction spaces 210 sequentially spaced along the second horizontal direction Y, and each heat conduction space 210 extends along the first horizontal direction X. The gap space 200 provides a channel for the flow and distribution of the phase change material 30. After the phase change material 30 enters the heat exchange space 110 from the filling inlet, it can extend through the gap space 200 and fill each heat conduction space 210 to infiltrate the plurality of heat exchange units 21.

[0093] Along the second horizontal direction Y, the fins 212 of the same position in the multiple heat exchange units 21 are located in the same vertical plane, so that the heat conduction spaces 210 of the same position in the multiple heat exchange units 21 are arranged side by side along the first horizontal direction, and are all connected with the gap space 200. Compared with the staggered arrangement of the multiple rows of heat conduction spaces 210 of the multiple heat exchange units 21, the multiple rows of heat conduction spaces 210 formed by the multiple gap spaces 200 and the multiple heat exchange units 21 in the embodiment of the present application form a phase change filling space that is connected vertically and horizontally in the heat exchange structure 20, and the phase change material 30 is easier to extend and distribute during the filling process. The phase change material 30 can flow along the predetermined path of the gap space 200 and the heat conduction space 210, reducing the problem of difficulty in extending in the gap, thereby further improving the filling efficiency.

[0094] It should be noted that the fin 212 is a straight fin, and the straight fin extends in the vertical direction. The design of the straight fin enables the phase change material 30 to maintain a relatively smooth flow path when flowing through the fin. Compared with corrugated fins or other fins with complex shapes, the straight fin reduces the sudden turn and vortex generation during the filling flow of the phase change material 30, thereby reducing the flow resistance.

[0095] See also Figure 6 , Figure 6 This is a structural schematic diagram of a heat conducting part of an embodiment of the present application. In another embodiment of the present application, in order to further increase the heat exchange area between the heat exchange unit 21 and the phase change material 30, the heat conducting part may also include a connecting part, which extends along the vertical direction Z and is connected to the fin 212. Optionally, the connecting part is arranged between two adjacent fins 212.

[0096] In the embodiment of the present application, among the multiple fins 212 arranged at intervals along the second horizontal direction Y, the preset spacing L between two adjacent fins 212 is the same, so that the phase change material 30 can maintain a relatively uniform distribution. In actual production, the fins 212 are punched to form a plurality of flanging holes, the heat exchange tube 211 is passed through the flanging holes, and the heat exchange tube 211 is fixed to the fin 212 by tube expansion processing to reduce the interface thermal resistance between the heat exchange tube 211 and the fin 212. Among them, the preset spacing L between two adjacent fins 212 depends on the height of the flanging hole. Taking the heat exchange tube 211 with a diameter of φ7mm as an example, the fin 212 matched therewith can be processed to have a flanging hole with a height that meets h∈(0mm, 2mm], then the preset spacing L between two adjacent fins 212 should not be greater than 2mm, otherwise the processing of the fin 212 is difficult to meet the design requirements.

[0097] During the design stage, the preset spacing L between two adjacent fins 212 also needs to consider the particle size of solid particles such as the nucleating agent in the phase change material 30. The maximum particle size of the solid particles in the phase change material 30 is Dmax, so the preset spacing L should not be too small. L satisfies: L>Dmax, so as to avoid the solid particles being unable to enter the heat conduction space 210 and accumulating on the top of the heat exchange unit 21, affecting the heat storage performance.

[0098] In one embodiment of the present application, the phase change material 30 includes the following components: 90wt.%-95wt.% sodium acetate trihydrate, 1wt.%-4wt.% disodium hydrogen phosphate dodecahydrate, 0.5wt.%-1.5wt.% carboxymethyl cellulose and 0.2wt.%-1.5wt.% pearl expansion rock. The phase change temperature T of the phase change material 30 meets the following conditions: 56°≤T≤58°, which meets the needs of domestic hot water. Specifically, sodium acetate trihydrate, as the base material of the phase change material 30, has a suitable phase change temperature and a high phase change latent heat, and plays a heat storage function. Carboxymethyl cellulose, as a thickener, can increase the viscosity and cohesion of the phase change material 30, and prevent leakage and separation of the liquid phase during the phase change process. Disodium hydrogen phosphate dodecahydrate and pearl expanded rock are used as nucleating agents to improve the supercooling of the phase change material 30, wherein the pearl expanded rock will not dissolve at high temperature, and the particle size D1 of the pearl expanded rock satisfies: 0.2mm≤D1≤1.4mm. Based on this, the preset spacing L between two adjacent fins 212 can be 1.5mm.

[0099] The pipelines of the heat exchange structure 20 of the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0100] See also Figure 7-Figure 9 , Figure 7 Schematic diagram of a piping structure of a heat exchange structure 20 according to an embodiment of the present application. Figure 8 A schematic diagram of a pipeline structure of another heat exchange structure 20 in an embodiment of the present application, Fig. 9 for Figure 8 The heat exchange structure 20 further includes a plurality of inlet headers 22, a plurality of outlet headers 23, a plurality of inlet manifolds 24, and a plurality of outlet manifolds 25, and the heat exchange unit 21 further includes a plurality of transfer tube groups. The inlets of the plurality of heat exchange tubes 211 are connected to the inlet manifold 24 through a portion of the transfer tube group, the inlet manifold 24 is connected to the inlet header 22, the outlets of the plurality of heat exchange tubes 211 are connected to the outlet header 25 through another portion of the transfer tube group, and the outlet header 25 is connected to the outlet header 23, so that the plurality of heat exchange tubes 211 in the heat exchange unit 21 are connected to the external pipeline through the inlet header 22 and the outlet header 23 to achieve heat exchange.

[0101] The heat exchange tube 211 has a plurality of straight tube sections arranged at intervals along the vertical direction, and the straight tube sections extend along the second horizontal direction Y. The heat exchange tube also includes a curved tube section, which is arranged on opposite sides of the straight tube section along the second horizontal direction Y and connected between two adjacent straight tube sections. The plurality of straight tube sections and the plurality of curved tube sections are sequentially connected to form the heat exchange tube 211. In the embodiment of the present application, each straight tube section in the heat exchange tube 211 extends along the second horizontal direction Y and is correspondingly penetrated through the plurality of fins to increase the heat exchange area of ​​the heat exchange unit.

[0102] In the embodiment of the present application, each inlet manifold 22 is connected to the inlet of the heat exchange tube 211 of the multiple heat exchange units 21, and each outlet manifold 23 is connected to the outlet of the heat exchange tube 211 of the multiple heat exchange units 21, wherein, in the vertical direction, the multiple inlet manifolds 22 and the multiple outlet manifolds 23 are all located above the multiple heat exchange units 21 to facilitate installation by staff, which helps to improve installation efficiency and safety, and the multiple inlet manifolds 22 and the multiple outlet manifolds 23 are installed in the heat exchange shell 10 to reduce the risk of displacement of the inlet manifolds 22 and the outlet manifolds 23 during transportation and use.

[0103] Optionally, in the second horizontal direction X, a plurality of inlet manifolds 22 and a plurality of outlet manifolds 23 are staggered, and the staggered arrangement facilitates the maintenance and inspection of the inlet manifolds 22 and the outlet manifolds 23. When these components need to be cleaned, replaced or inspected, the staggered layout can reduce interference with adjacent components, making the operation easier and faster.

[0104] In the embodiment of the present application, along the flow direction of the fluid in the heat exchange tubes 211, an inlet header 24 is arranged upstream of the plurality of heat exchange tubes 211 to evenly distribute the fluid in the inlet header 22 to each heat exchange tube 211, and the plurality of inlet headers 24 are connected to the plurality of inlet headers 22 one by one, and the inlet headers 24 are connected to the inlets of the heat exchange tubes 211 of the plurality of heat exchange units 21. An outlet header 25 is arranged downstream of the plurality of heat exchange tubes 211 to collect the fluid in the plurality of heat exchange tubes 211, and the plurality of outlet headers 25 are connected to the plurality of outlet headers 23 one by one, and the outlet headers 25 are connected to the outlets of the heat exchange tubes 211 of the plurality of heat exchange units 21. In the vertical direction, the inlet header 24 and the outlet header 25 are both located above the plurality of heat exchange units 21, which is convenient for connecting the inlet header 22 and the outlet header 23, and is convenient for the staff to install and overhaul, which helps to improve the installation efficiency and safety.

[0105] It should be noted that the multiple heat exchange units 21 are arranged along the first horizontal direction X, and the multiple heat exchange tubes 211 in each heat exchange unit 21 are arranged at intervals along the first horizontal direction. Therefore, the multiple inlet headers 24 and the multiple outlet headers 25 extend along the first horizontal direction X respectively, and are arranged side by side along the second horizontal direction Y to ensure that the fluid in each heat exchange unit 21 can smoothly flow into or out of the above-mentioned headers.

[0106] In order to enable the inlet of each heat exchange tube 211 to be connected to the inlet header 24 and the outlet to be connected to the outlet header 25, the heat exchange unit 21 is also provided with a plurality of transfer tube groups, each transfer tube group includes a transfer main pipe 2101 and a transfer branch pipe 2102, the transfer branch pipe 2102 has a plurality of transfer ends, one end of the transfer main pipe 2101 is connected to one of the transfer ends of the transfer branch pipe 2102. The transfer tube group includes an inlet transfer tube group 213 and an outlet transfer tube group 214; the other end of the transfer main pipe 2101 of the inlet transfer tube group 213 is connected to the inlet header 24, and the remaining transfer ends of the transfer branch pipe 2102 are connected to the inlets of the plurality of heat exchange tubes 211 in a one-to-one correspondence; the other end of the transfer main pipe 2101 of the outlet transfer tube group 214 is connected to the outlet header 25, and the remaining transfer ends of the transfer branch pipe 2102 are connected to the outlets of the plurality of heat exchange tubes 211 in a one-to-one correspondence. It can be understood that the design of multiple adapter ends of the adapter branch pipe 2102 simplifies the pipeline layout. Multiple pipelines that may have been required to connect the inlet and outlet of each heat exchange tube 211 separately are integrated into the adapter branch pipe 2102. The space occupied by complex pipelines is released, providing more possibilities for the installation of other components, making the layout of the heat exchange structure 20 more compact and reasonable.

[0107] Please go back Figure 4It can be seen that a part of the multiple heat exchange tubes 211 of each heat exchange unit 21 is a heat storage tube 215, and another part is a heat release tube 216, wherein the heat storage tube 215 is used to communicate with the heat source so that the high-temperature heat exchange medium and the phase change material 30 can exchange heat to achieve heat storage, and the heat release tube is used to communicate with the municipal waterway so that the municipal cold water can exchange heat with the phase change material 30 to achieve heat release. In order to reduce the loss of heat during the transfer process and improve the thermal efficiency of the heat exchange unit 21, the heat storage tube 215 and the heat release tube 216 are arranged alternately. Optionally, the number of the heat storage tube 215 and the heat release tube 216 is the same, and the multiple heat storage tubes 215 and the multiple heat release tubes 216 in each heat exchange unit 21 are arranged periodically along the first horizontal direction X. The periodic arrangement helps to achieve uniform distribution and stable release of heat, and avoid the occurrence of local overheating or overcooling.

[0108] At the beginning of the heat storage process, the temperature of the fluid in the heat storage tube 215 gradually decreases with the flow sideways. Therefore, the heat storage tube inlet 215a is arranged at the straight tube section port on the upper side along the vertical side, and the heat storage tube outlet 215b is arranged at the straight tube section port on the lower side along the vertical side, so that the phase change material 30 gradually undergoes a solid-liquid phase change from top to bottom at the beginning of the heat storage process. The phase change material 30 located on the upper side of the heat exchange structure 20 can extend upward after the solid-liquid phase change occurs, thereby avoiding damage to the heat exchange module 1. During the heat release process, the temperature of the fluid in the heat release pipe 216 gradually increases with the flow direction. Therefore, the heat release pipe inlet 216a is arranged at the straight pipe section port on the vertical downward side, and the heat release pipe outlet 216b is arranged at the straight pipe section port on the vertical upward side, so that the temperature change trend from top to bottom in the heat exchange structure 20 remains consistent. This arrangement also allows the phase change material 30 located on the lower side of the heat exchange structure 20 to preferentially transform from liquid to solid in the later stage of the heat release process.

[0109] A portion of the multiple groups of transfer tube groups are heat storage transfer tube groups, and another portion of the groups are heat release transfer tube groups. The multiple heat storage tube inlets 215a are connected to one of the inlet manifolds 24 through one of the heat storage transfer tube groups, and the heat storage tube outlets 215b are connected to one of the outlet manifolds 25 through another group of heat storage transfer tube groups to form a heat storage flow path, which is connected to a heat source through an inlet manifold 22 and an outlet manifold 23. The heat source transports a high-temperature heat exchange medium to the heat storage flow path, so that the high-temperature heat exchange medium exchanges heat with the phase change material 30 and causes the phase change material 30 to absorb and store heat by phase change, thereby realizing heat storage of the heat exchange module 1. The inlets 216a of the multiple heat release tubes are connected to another inlet manifold 24 through a group of heat release transfer tubes, and the outlets 216b of the heat release tubes are connected to another outlet manifold 25 through another group of heat release transfer tubes to form a heat release flow path. The heat release flow path is connected to the municipal waterway through an inlet main pipe 22 and an outlet main pipe 23. The cold water in the municipal waterway absorbs heat from the phase change material 30 after flowing through the heat release flow path. The phase change material 30 undergoes a reverse phase change and releases heat, thereby realizing the heat release of the heat exchange module 1.

[0110] See also Fig.10 , Fig.10 for Figure 8 , the inlet manifold 22 includes a heat storage inlet manifold 221 and a heat release inlet manifold 222. The heat storage inlet manifold 221 is connected to the inlet manifold 24 of the heat storage flow path, and the heat release inlet manifold 222 is connected to the inlet manifold 24 of the heat release flow path. The outlet manifold 23 includes a heat storage outlet manifold 231 and a heat release outlet manifold 232. The heat storage outlet manifold 231 is connected to the outlet manifold 25 of the heat storage flow path, and the heat release outlet manifold 232 is connected to the outlet manifold 25 of the heat release flow path. The heat storage inlet manifold 221 and the heat storage outlet manifold 231 are arranged relatively along the second horizontal direction Y, and the heat release inlet manifold 222 and the heat release inlet manifold 222 are arranged relatively along the second horizontal direction Y. In order to ensure the consistency of the temperature change trend in the heat exchange module 1, along the second horizontal direction Y, the heat storage inlet main pipe 221 and the heat release outlet main pipe 232 are located on the same side, and the heat storage inlet main pipe 221 is located on the relatively outer side of the heat release outlet main pipe 232, the heat storage outlet main pipe 231 and the heat release inlet main pipe 222 are located on the same side, and the heat release inlet main pipe 222 is located on the relatively outer side of the heat storage outlet main pipe 231.

[0111] See also Fig.11 , Fig.11 for Figure 8The schematic diagram of the front view of the heat storage device is shown in FIG. 2 , in which the transfer pipe 2101 of each transfer pipe group includes a vertical section and a horizontal section arranged at an angle, and the vertical section extends in the vertical direction. At the beginning of the heat storage process, the temperature of the heat storage pipe outlet 215b is lower than the temperature of the heat storage pipe inlet 215a. In order to reduce the influence of the heat storage transfer pipe group connected to the heat storage pipe outlet 215b on the heat transfer part and the phase change material 30 in the heat transfer space 210, in the second horizontal direction Y, the vertical section of the transfer pipe 2101 on the side of the heat storage pipe inlet 215a is located on the side of the vertical section of the transfer pipe 2101 on the side of the heat storage pipe outlet 215b close to the heat transfer part. In the vertical direction Z, the vertical section of the transfer pipe 2101 on the side of the heat storage pipe inlet 215a is located below the vertical section of the transfer pipe 2101 on the side of the heat storage pipe outlet 215b.

[0112] Similarly, the temperature of the heat release pipe inlet 216a is lower than the temperature of the heat release pipe outlet 216b. In order to reduce the influence of the heat release adapter pipe group connected to the heat release pipe inlet 216a on the heat transfer part and the phase change material 30 in the heat transfer space 210, in the second horizontal direction Y, the vertical section of the adapter main pipe 2101 on the side of the heat release pipe inlet 216a is located on the side of the vertical section of the adapter main pipe 2101 on the side of the heat release pipe outlet 216b away from the heat transfer part; in the vertical direction, the vertical section of the adapter main pipe 2101 on the side of the heat release pipe inlet 216a is located above the vertical section of the adapter main pipe 2101 on the side of the heat release pipe outlet 216b.

[0113] The multiple transfer ends of the transfer branch pipe 2102 include a first transfer end 2102a and multiple second transfer ends 2102b. The first transfer end 2102a is connected to the transfer main pipe 2101. Fig.12 , Fig.12 This is a structural schematic diagram of a connecting branch pipe 2102 according to an embodiment of the present application, wherein the axial direction of the first connecting end 2102a is set at an angle to the axial direction of the second connecting end 2102b, so that the connecting branch pipe 2102 is set on one side of the heat-conducting portion along the second horizontal direction Y and is connected to the outlets of multiple heat exchange tubes 211.

Fig.14 A schematic diagram of the structure of another adapter branch pipe 2102 in an embodiment of the present application, optionally, the axial direction of the first adapter end 2102a is parallel to the axial direction of the second adapter end 2102b, wherein the adapter branch pipe 2102 is arranged on one side of the heat conduction part along the vertical direction Z and is connected to the outlets of multiple heat exchange tubes 211 through a U-tube or a bend pipe.

[0115] In one embodiment of the present application, in order to ensure heat exchange efficiency, the material of the heat exchange tube 211 is at least one of copper, copper alloy, and stainless steel.

[0116] In another embodiment of the present application, the heat exchange between the phase change material 30 and the pipeline of the heat exchange structure 20 is mainly completed through the heat exchange tube 211. In order to transfer heat more effectively and improve the heat exchange efficiency, the heat exchange tube 211 is made of copper, and the inlet main pipe 22, the outlet main pipe 23, the inlet collecting pipe 24 and the outlet collecting pipe 25 are made of stainless steel. Stainless steel has excellent corrosion resistance and durability and can withstand higher working pressure and temperature changes.

[0117] In another embodiment of the present application, in order to improve the thermal efficiency in the heat storage process, the heat storage tube and the transition tube group connected to the heat storage tube are made of aluminum, and in order to improve the durability of the heat release flow path, the heat release tube and the transition tube connected to the heat release tube are made of stainless steel.

[0123] See also Fig.21 , Fig.21 This is a schematic diagram of the installation structure of a third limit member 43 of an embodiment of the present application.

[0124] The heat exchange housing 10 of the heat exchange module 1 in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0125] Please continue reading Figure 1-Figure 2 The heat exchange shell 10 includes a first shell 11, a second shell 12 and an insulation layer 13. The first shell 11 has a heat exchange space 110 inside. The heat exchange structure 20 is at least partially installed in the heat exchange space 110. The phase change material 30 is filled in the heat exchange space 110. The insulation layer 13 is arranged between the first shell 11 and the second shell 12.

[0126] See also Figure 22-Figure 24 , Fig. 22 This is a perspective structural diagram of a heat exchange module 1 according to an embodiment of the present application. Fig.23 is a schematic structural diagram of a first housing 11 according to an embodiment of the present application. Fig.24 This is a schematic diagram of the exploded structure of a first shell 11 of an embodiment of the present application, wherein the first shell 11 includes a shell body 111, a first top plate 112 and a first bottom plate 113, wherein the shell body 111 is a cylindrical structure, the first top plate 112 and the first bottom plate 113 are relatively arranged along the vertical direction Z, the first top plate 112 is connected to the upper end of the shell body 111 along the vertical direction Z, the first bottom plate 113 is connected to the lower end of the shell body 111 along the vertical direction Z, the first top plate 112, the shell body 111 and the first bottom plate 113 are connected in sequence and enclose and define a heat exchange space 110.

[0128] In practical applications, the heat exchange module 1 is likely to be exposed to a high temperature environment during long-distance transportation, especially during container transportation, causing the phase change material 30 inside the first shell 11 to undergo a phase change, thereby causing the first shell 11 to deform due to the liquid phase change material 30. Optionally, the first shell 11 may be made of metal, such as stainless steel, to avoid damage due to force or heat during long-distance transportation.
