Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to a water heater. Background Technology

[0002] Water heaters generally have a heat storage function, which is achieved through a heat storage device to store heat so that users can have hot water promptly. There are various types of heat storage devices, with phase change media being particularly favored due to their high heat storage density.

[0003] The phase change medium is used to fill the space between the heat exchanger and the inner liner. When the heat exchanger is installed into the inner liner, due to its large size and inconvenient positioning, there is a risk of collision with the inner liner, which may cause damage to the heat exchanger or the inner liner and pose a safety hazard.

[0004] In addition, after the heat exchange device is installed in the inner tank, the lack of a reinforcing structure between the heat exchange device and the inner tank may cause the heat exchange device to shake and shift during transportation and operation, which will also affect the working effect of the water heater. Summary of the Invention

[0005] The purpose of this utility model is to provide a water heater that solves the problems existing in the prior art, such as difficulty in positioning the heat exchange device during installation into the inner tank, easy collision with the inner tank, poor stability of the heat exchange device, and risk of shaking.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] A water heater comprising:

[0008] The outer casing has an internal mounting cavity formed therein;

[0009] An inner liner is disposed in the mounting cavity, and a heat exchange cavity is formed in the inner liner;

[0010] A heat exchange device located in the heat exchange cavity includes a heat storage pipeline, a heat release pipeline, and heat exchange fins. Both the heat storage pipeline and the heat release pipeline include a bent section and a direct flow section. Each heat exchange fin is vertically arranged between the direct flow sections.

[0011] The heat exchange device further includes a first side plate and a second side plate, which are located on both sides of the heat exchange device. The bent sections on both sides of the heat exchange device are located on the outer sides of the first side plate and the second side plate, respectively. A positioning member is provided at the bottom of the first side plate and / or the second side plate. The end of the positioning member extends to the outer side of the bent section on the corresponding side. A guide surface is formed on the positioning member. The guide surface is used to guide the heat exchange device into the heat exchange cavity during installation.

[0012] In some embodiments of this application, the positioning element includes:

[0013] A fixing part is detachably connected to the first side plate or the second side plate;

[0014] A lateral extension portion, which is connected to the fixing portion, and extends outward in a direction away from the first side plate or the second side plate;

[0015] A guide portion, which is connected to the lateral extension portion and is set at an angle to the lateral extension portion, and the guide surface is formed on the guide portion;

[0016] A longitudinal extension is connected to the end of the guide portion and extends upward toward the heat exchange device.

[0017] The positioning component is connected to the first or second side plate via the fixing part. The end of the lateral extension extends to the outside of the corresponding first or second side plate by a certain distance. The guide part extends obliquely upward, and the guide surface is located on the outside of the guide part. When the heat exchange device is installed in the heat exchange cavity, the guide surface contacts the inner wall of the heat exchange cavity to facilitate the positioning of the heat exchange device and improve the installation efficiency. The longitudinal extension part is used to protect the heat storage pipeline and heat release pipeline connected to the outside of this side.

[0018] In some embodiments of this application, a first fixing member and a second fixing member are provided between the first side plate and the second side plate. There are two of each of the first fixing member and the second fixing member. The first fixing member is connected above the first side plate and the second side plate, and the second fixing member is connected below the first side plate and the second side plate.

[0019] The first and second fixing components connect the first and second side plates, which helps improve the overall integrity of the heat exchange device and facilitates handling and installation. Both the first and second fixing components are beam structures with small volume, which reduces the impact on the size of the heat exchanger and helps ensure the filling efficiency and heat exchange efficiency of the phase change material between the heat exchange device and the inner liner.

[0020] In some embodiments of this application, the inner liner includes a liner body and a cover body. The liner body is a shell structure with an opening at the top. A connecting recess is formed on the periphery of the opening of the liner body. A connecting outer edge is formed on the periphery of the cover body. The cover body is fixed in the connecting recess through the connecting outer edge. A sealing element is also provided between the connecting recess and the connecting outer edge.

[0021] The cover is connected to the connecting recess via the connecting outer edge, so that the cover and the inner liner form a surface contact, which improves the connection sealing. A sealing element is set between the connecting recess and the connecting outer edge to further improve the sealing effect and reduce heat leakage in the heat exchange cavity and volatilization of phase change material.

[0022] In some embodiments of this application, a reinforcing member is further provided between the heat exchange device and the tank body. The reinforcing member includes a reinforcing vertical part, a hanging part, and a reinforcing horizontal part. The hanging part and the reinforcing horizontal part are respectively disposed at both ends of the reinforcing vertical part. The hanging part is detachably connected to the tank body, and the reinforcing horizontal part is detachably connected to the heat exchange device.

[0023] After the heat exchange device is installed in the heat exchange cavity, it is further connected and fixed to the inner liner by the reinforcement, which helps to improve the stability of the heat exchange device and prevent the heat exchange device from shifting during transportation and operation, thereby improving equipment safety and working efficiency.

[0024] In some embodiments of this application, a plurality of protective uprights are provided at intervals on both sides of the first side plate and the second side plate, and the protective uprights are used to protect the corresponding bending sections.

[0025] The end of the protective upright is higher than the bending section, which can protect the bending section during assembly and prevent the bending section from colliding with the outer wall of the heat exchange cavity or the outer packaging shell.

[0026] In some embodiments of this application, the heat storage pipeline includes a heat storage input end and a heat storage output end. The heat storage input end is connected to the corresponding DC section located at the bottom of the heat exchange device through the heat storage input pipeline, and the heat storage output end is connected to the corresponding DC section located at the top of the heat exchange device through the heat storage output pipeline.

[0027] The heat release pipeline includes a heat release input end and a heat release output end. The heat release pipeline is connected to the DC section located at the bottom of the heat exchange device through the heat release input pipeline, and the heat release output end is connected to the corresponding DC section located at the top of the heat exchange device through the heat release output pipeline.

[0028] In some embodiments of this application, the heat exchange device is provided with a first bracket, the two ends of which are fixed to corresponding first fixing members. The heat storage input pipe, the heat storage output pipe, the heat release input pipe, and the heat release output pipe located at the top of the heat exchange device are fixed to the first bracket by clamps; and / or

[0029] The heat exchange device is provided with a second bracket, and the two sides of the second bracket are fixed to the corresponding protective uprights. The heat storage input pipeline and the heat release input pipeline are fixed to the second bracket by clamps.

[0030] At least a portion of the heat storage input pipeline and the heat release input pipeline are fixed on the first or second bracket, which improves the stability of the pipeline connection, limits the relative position of the pipeline and protects the pipeline, and helps to smoothly complete the assembly of the heat exchange device in the inner tank.

[0031] In some embodiments of this application, the heat exchange device is further provided with a lifting component, which is detachably connected to the first bracket by fasteners.

[0032] Multiple lifting components are provided and distributed on the top of the heat exchanger to facilitate lifting during the assembly and disassembly of the heat exchanger.

[0033] In some embodiments of this application, a reinforcing member is further provided on the outer wall of the inner liner, the reinforcing member including at least two reinforcing crossbars spaced apart on the outer wall of the inner liner along the height direction of the inner liner.

[0034] Because phase change media have high latent heat, the heat absorption and release processes of phase change media are accompanied by volume changes. When the phase change media undergoes changes, it mainly relies on the inner liner to withstand pressure. The reinforcing members installed on the outside of the inner liner help to improve the structural strength of the inner liner and reduce the deformation of the inner liner during the volume changes of the phase change media.

[0035] Strengthening the spacing of the crossbeams allows for reinforcement of different locations within the inner liner, improving the overall structural strength of the inner liner and reducing the risk of deformation.

[0036] Compared with the prior art, the advantages and positive effects of this utility model are:

[0037] The water heater involved in this application has a positioning element at the bottom of the first side plate and / or the second side plate of its heat exchange device. A guide surface is formed on the positioning element. When the heat exchange device is hoisted into the heat exchange cavity from top to bottom, the positioning element guides the heat exchange device into the heat exchange cavity through the guide surface. The guide surface contacts the inner wall of the heat exchange cavity, which helps to improve the positioning accuracy of the heat exchange device during installation and improves the installation efficiency. In addition, the positioning element also protects the heat storage pipe and the heat release pipe, preventing the heat storage pipe and the heat release pipe from colliding with the inner tank during the installation of the heat exchange device, thereby improving safety.

[0038] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0077] refer to Figure 1 , Figure 2 This application proposes a water heater, which includes an outer shell 100, an inner tank 200 and a heat exchange device 500. An installation cavity is formed inside the outer shell 100, and the inner tank 200 is disposed in the installation cavity.

[0078] A heat-insulating gap is formed between the inner liner 200 and the outer shell 100, and a heat-insulating layer 300 is provided in the heat-insulating gap to reduce the heat exchange between the inner liner 200 and the outside.

[0079] The insulation layer 300 adopts a design of applying insulation cotton and VIP heat insulation board, or it can adopt a design of integral polyurethane foam.

[0080] The inner liner 200 has a heat exchange cavity. The inner liner 200 is made of metal, which improves its corrosion resistance and water resistance. It is recommended to add a waterproof layer such as an epoxy resin coating or a rubber lining to the inner surface of the inner liner 200.

[0081] The heat exchange cavity is filled with a phase change medium, and the heat exchange device 500 is located inside the phase change medium.

[0082] refer to Figure 5 , Figure 6 The heat exchange device 500 includes a heat storage pipe 521, a heat release pipe 522, and heat exchange fins 510. The heat storage pipe 521 transfers heat from the high-temperature water generated by the heat pump, solar energy, or gas to the phase change medium for storage through the heat exchange fins 510.

[0083] When a user uses hot water, the phase change medium heats the low-temperature water in the heat dissipation pipe 522 through the heat exchange fins 510 and then outputs it for the user's use.

[0084] Both the heat storage pipeline 521 and the heat release pipeline 522 include a bent section and a direct flow section, and the heat exchange fins 510 are vertically connected between the direct flow sections.

[0085] The heat exchange device 500 also includes a first side plate 540 and a second side plate 550, which are located on both sides of the heat exchange device 500 and are arranged parallel to the heat exchange fins 510.

[0086] The bent sections on both sides of the heat exchange device 500 are located on the outside of the first side plate 540 and the second side plate 550, respectively. A positioning member 600 is provided at the bottom of the first side plate 540 and / or the second side plate 550. The end of the positioning member 600 extends to the outside of the heat storage pipe 521 and the heat release pipe 522. Specifically, the outer end of the positioning member 600 extends to the outside of the corresponding side bent section to form protection for the side bent section.

[0087] The positioning member 600 has a guide surface formed thereon, which is used to guide the heat exchanger 500 into the heat exchange cavity during installation.

[0088] When the heat exchanger 500 is hoisted into the heat exchanger cavity from top to bottom, the positioning component 600 guides the heat exchanger 500 into the heat exchanger cavity through the guide surface. The guide surface contacts the inner wall of the heat exchanger cavity, which helps to improve the positioning accuracy of the heat exchanger 500 during installation and improves the installation efficiency. In addition, the positioning component 600 also protects the heat storage pipe 521 and the heat release pipe 522, preventing them from colliding with the inner tank 200 during the installation of the heat exchanger 500, thus improving safety.

[0089] refer to Figure 7 In some embodiments of this application, the positioning member 600 includes a fixing part 610, a lateral extension part 620, a guiding part 630, and a longitudinal extension part 640.

[0090] The fixing part 610 is detachably connected to the first side plate 540 or the second side plate 550.

[0091] The lateral extension 620 is connected to the fixing part 610 and extends outward in a direction away from the first side plate 540 or the second side plate 550.

[0092] The guide portion 630 is connected to the lateral extension portion 620 and is set at an angle to the lateral extension portion 620, and the guide surface is formed on the guide portion 630.

[0093] The longitudinal extension 640 is connected to the end of the guide portion 630 and extends upward toward the heat exchange device 500.

[0094] The positioning member 600 is connected to the first side plate 540 or the second side plate 550 via the fixing part 610. The end of the lateral extension part 620 extends to the outside of the corresponding first side plate 540 or second side plate 550 by a certain distance. The guide part 630 extends obliquely upward, and the guide surface is located on the outside of the guide part 630. When the heat exchange device 500 is installed in the heat exchange cavity, the guide surface contacts the inner wall of the heat exchange cavity to facilitate the positioning of the heat exchange device 500 and improve the installation efficiency. The longitudinal extension part 640 is used to protect the heat storage pipe 521 and the heat release pipe 522 connected to the outside of this side.

[0095] To facilitate processing, the lateral extension 620, the guide 630, and the longitudinal extension 640 are designed to be integrally formed. The lateral extension 620 is vertically connected to the fixing part 610 by welding or mechanical connection.

[0096] In some embodiments, the fixing part 610 is provided with at least one fixing hole, and the first side plate 540 or the second side plate 550 is provided with a connecting hole at a corresponding position. The fastener passes through the fixing hole to connect the fixing part 610 to the corresponding connecting hole, thereby realizing the connection and fixing of the fixing part 610.

[0097] For ease of understanding, the first side plate 540 along the height direction of the heat exchange device 500 is defined as the first direction, and the direction perpendicular to the first direction on the end face is defined as the second direction. At least two positioning members 600 are provided at intervals along the second direction of the first side plate 540 or the second side plate 550 to improve the stability of the heat exchange device 500 installation and avoid skewing.

[0098] Refer again Figure 5 In some embodiments of this application, a first fixing member 531 and a second fixing member 532 are provided between the first side plate 540 and the second side plate 550. There are two of each of the first fixing member 531 and the second fixing member 532. The first fixing member 531 is connected above the first side plate 540 and the second side plate 550, and the second fixing member 532 is connected below the first side plate 540 and the second side plate 550.

[0099] The first fixing member 531 and the second fixing member 532 connect the first side plate 540 and the second side plate 550, which helps to improve the overall integrity of the heat exchange device 500 and facilitates handling and installation. Both the first fixing member 531 and the second fixing member 532 are beam structures with small volume, which reduces the impact on the size of the heat exchanger and helps to ensure the filling efficiency and heat exchange efficiency of the phase change material between the heat exchange device 500 and the inner liner 200.

[0100] In some embodiments, the cross-sectional shape of the first fastener 531 and the second fastener 532 is U-shaped, which improves the structural strength of the first fastener 531 and the second fastener 532.

[0101] Both ends of the first fixing member 531 and the second fixing member 532 are provided with bent portions (not shown). The bent portions are fixed to the inner side of the first side plate 540 and the second side plate 550 by fasteners, so as to achieve connection and fixation with the first side plate 540 and the second side plate 550.

[0102] Combination Figure 4 , Figure 8 as well as Figure 10 In some embodiments of this application, the inner liner 200 includes a liner body 210 and a cover body 220. The liner body 210 is a shell structure with an opening at the top. A connecting recess 211 is formed on the periphery of the opening position of the liner body 210. A connecting outer edge 222 is formed on the periphery of the cover body 220. The cover body 220 is fixed in the connecting recess 211 by the connecting outer edge 222.

[0103] Specifically, an inner upright portion 212 and an outer upright portion 213 are formed around the opening of the gallbladder 210. The outer upright portion 213 is located outside the inner upright portion 212, and a connecting recess 211 is formed between the inner upright portion 212 and the outer upright portion 213.

[0104] A sealing element 230 is also provided between the connecting recess 211 and the connecting outer edge 222. The sealing element 230 is specifically a sealing strip. The connecting outer edge 222 and the bottom of the connecting recess 211 are respectively provided with connecting holes. Fasteners pass through the sealing strip and the corresponding connecting holes to fix the connecting outer edge 222 to the bottom of the connecting recess 211.

[0105] The cover 220 is connected to the connecting recess 211 via the connecting outer edge 222, so that the cover 220 and the inner liner 200 form a surface contact, improving the connection sealing. A sealing element 230 is provided between the connecting recess 211 and the connecting outer edge 222 to further improve the sealing effect and reduce heat leakage in the heat exchange cavity and volatilization of the phase change material.

[0106] refer to Figure 5 , Figure 8 as well as Figure 9 In some embodiments of this application, a reinforcing member 240 is provided between the heat exchange device 500 and the tank 210. The reinforcing member 240 includes a reinforcing vertical part 241, a hanging part 242, and a reinforcing horizontal part 243. The hanging part 242 and the reinforcing horizontal part 243 are respectively disposed at both ends of the reinforcing vertical part 241. The hanging part 242 is detachably connected to the tank 210, and the reinforcing horizontal part 243 is detachably connected to the heat exchange device 500.

[0107] After the heat exchanger 500 is installed into the heat exchange cavity, it is further connected and fixed to the inner liner 200 by the reinforcement 240, which helps to improve the stability of the heat exchanger 500 and prevent the heat exchanger 500 from shifting during transportation and operation, thereby improving equipment safety and working efficiency.

[0108] Specifically, the reinforcing horizontal part 243 is vertically arranged at the bottom of the reinforcing vertical part 241, and the hanging part is a bend formed on the top of the reinforcing vertical part 241 and away from the direction of the reinforcing horizontal part 243. After the heat exchanger is installed in the heat exchange cavity, the operator hangs the hanging part on the inner vertical part 212 to fix the reinforcing horizontal part 243 to the first side plate 540, the second side plate 550 or the first fixing part 531.

[0109] In some embodiments of this application, a plurality of protective uprights are provided at intervals on both sides of the first side plate 540 and the second side plate 550, and the protective uprights are used to protect the corresponding bending sections.

[0110] refer to Figure 5 , Figure 11 Specifically, the first side plate 540 is provided with a plurality of first protective uprights 541 on both sides, and the second side plate 550 is provided with a plurality of second protective uprights 551 on both sides.

[0111] Specifically, both the first side plate 540 and the second side plate 550 have bends perpendicular to the corresponding side plates on their periphery, and protective uprights are formed on the bends.

[0112] The end of the protective upright is higher than the bending section, which can protect the bending section during assembly and prevent the bending section from colliding with the outer wall of the heat exchange cavity or the outer packaging shell 100.

[0113] In addition, the protective upright can also play a guiding and positioning role during installation. Since the gap between the heat exchange device 500 and the inner tank 200 should be as small as possible, the protective upright design can effectively control the gap and make it as small as possible. In addition, it can also avoid the problems of excessive bending height on the first side plate 540 and the second side plate 550, which would lead to increased overall weight, waste of material costs, and encroachment on some phase change material volume, reducing heat exchange efficiency.

[0114] In some embodiments of this application, the heat storage pipeline 521 includes a heat storage input end and a heat storage output end. The heat storage input end is connected to a corresponding DC section located at the bottom of the heat exchange device 500 through the heat storage input pipeline, and the heat storage output end is connected to a corresponding DC section located at the top of the heat exchange device 500 through the heat storage output pipeline.

[0115] The heat release pipeline 522 includes a heat release input end and a heat release output end. The heat release pipeline 522 is connected to the DC section located at the bottom of the heat exchange device 500 through the heat release input pipeline, and the heat release output end is connected to the corresponding DC section located at the top of the heat exchange device through the heat release output pipeline.

[0116] Both the heat storage input pipeline and the heat release input pipeline are connected to the bottom of the heat exchange device 500, adopting a bottom-in, top-out design. This design can promote convection and improve the charging and releasing efficiency.

[0117] The heat release input pipeline and heat release output pipeline are connected to the inlet and outlet of the domestic water supply, respectively, for inputting low-temperature water and outputting high-temperature water; the heat storage input pipeline and heat storage output pipeline are connected to the heat pump system for heat storage.

[0118] Continue to refer to Figure 5 , Figure 11 In some embodiments of this application, a first bracket 560 is provided on the heat exchange device 500, and both ends of the first bracket 560 are fixed to corresponding first fixing members 531. The heat storage input pipe, heat storage output pipe, heat release input pipe, and heat release output pipe located at the top of the heat exchange device 500 are fixed to the first bracket 560 by clamps; and / or

[0119] A second bracket 570 is provided on the heat exchange device 500. The two sides of the second bracket 570 are fixed on the corresponding protective uprights. The heat storage input pipeline and the heat release input pipeline are fixed on the second bracket 570 by clamps.

[0120] At least a portion of the heat storage input pipeline and the heat release input pipeline are fixed on the first bracket 560 or the second bracket 570, which improves the stability of the pipeline connection, limits the relative position of the pipeline and protects the pipeline, and helps to smoothly complete the assembly of the heat exchange device 500 in the inner tank 200.

[0121] For ease of arrangement, both the heat storage input pipeline and the heat release input pipeline extend from the outside of the first side plate 540 to the bottom of the heat exchange device 500. The two ends of the second bracket 570 are fixed on the first protective upright 541 to fix the passing heat storage input pipeline and heat release input pipeline.

[0122] For details, please refer to Figure 12 Both the first support 560 and the second support 570 include a support crossbeam 501 and a support upright 502 disposed at both ends of the support crossbeam 501 and perpendicular to the support crossbeam 501.

[0123] The first bracket 560 is fixed to the first fixing member 531 by the support frame 502, and the second bracket 570 is fixed to the protective uprights formed on both sides of the second side plate 550 by the support frame 502.

[0124] To improve connection strength, the end dimension of the support frame 502 is designed to be larger than the dimensions at other locations, thereby improving the connection strength with the first fixing member 531 or the protective stand.

[0125] For example, but not limited to, two fasteners are provided on each support frame 502 for connecting and fixing to the first fixing member 531 or the protective frame.

[0126] In some embodiments of this application, the clamp fixes at least one pipe to the first bracket 560 or the second bracket 570. The clamp includes an arched snap-fit ​​portion 503 and connecting legs 504 formed at both ends of the snap-fit ​​portion 503. The connecting legs 504 are connected to the support crossbeam 501 by fasteners, and the pipe is fixed in the gap between the snap-fit ​​portion 503 and the support crossbeam 501.

[0127] The clamps can limit the relative position of the pipeline and protect the piping, which can help to smoothly complete the assembly of the heat exchanger into the inner tank 200.

[0128] In addition, limiting all pipelines to the first bracket 560 or the second bracket 570 helps to control the gap between the heat exchanger 500 and the inner tank 200, preventing the gap from becoming uncontrollable due to the influence of the pipelines.

[0129] In some embodiments of this application, the heat exchange device 500 is further provided with a lifting component 580, which is detachably connected to the first bracket 560 by fasteners.

[0130] The lifting component 580 specifically includes a connecting screw and a lifting ring set on the upper end of the connecting screw. The first bracket 560 is provided with a through mounting hole. The connecting screw passes through the corresponding mounting hole and is connected to the first bracket 560 by fastening nuts, etc., which facilitates lifting and avoids problems such as interference or entanglement between the lifting rope and the pipeline.

[0131] Multiple lifting components 580 are provided and distributed on the top of the heat exchanger 500 to facilitate lifting during the assembly and disassembly of the heat exchanger 500.

[0132] In some embodiments of this application, a reinforcing member 400 is also provided on the outer wall of the inner liner 200. The reinforcing member 400 includes at least two reinforcing crossbars 410 that are spaced apart along the height direction of the inner liner 200 on the outer wall of the inner liner 200.

[0133] Because phase change media have high latent heat, the heat absorption and release processes of phase change media are accompanied by volume changes. When the phase change media undergoes changes, it mainly relies on the inner liner 200 to bear the pressure. The reinforcing member 400 set on the outside of the inner liner 200 helps to improve the structural strength of the inner liner 200 and reduce the deformation of the inner liner 200 during the volume change process of the phase change media.

[0134] Strengthening the spacing of the crossbeams 410 can reinforce different locations of the inner liner 200, improving the overall structural strength of the inner liner 200 and reducing the risk of deformation.

[0135] Combination Figure 3 , Figure 4 The cover 220 is also provided with a rubber sleeve 221, and the heat storage input end, heat storage output end, heat release input end and heat release output end extend to the outside of the inner liner 200 through the corresponding rubber sleeve 221.

[0136] After the top cover is installed, the rubber sleeve 221 is tightened with the heat storage input end, heat storage output end, heat release input end and heat release output end to achieve a seal and prevent the phase change material from volatilizing and leaking.

[0137] Heat pumps, solar energy, and natural gas, among other energy sources, deliver heated high-temperature water from the heat storage input end to the heat storage pipe 521. The heat is then transferred to the phase change medium for storage via heat exchange fins 510. In use, low-temperature water is delivered from the heat release input end to the heat release pipe 522 of the heat exchange device 500. The heat in the phase change medium is transferred to the heat release pipe 522 via the heat exchange fins 510. After being heated, the low-temperature water in the heat release pipe 522 is output to the user terminal from the heat release output end.

[0138] In some embodiments of this application, a reinforcing member 400 is also provided on the outer wall of the inner liner 200, the reinforcing member 400 being used to improve the structural strength of the inner liner 200.

[0139] Because phase change media have high latent heat, the heat absorption and release processes of phase change media are accompanied by volume changes. When the phase change media undergoes changes, it mainly relies on the inner liner 200 to bear the pressure. The reinforcing member 400 set on the outside of the inner liner 200 helps to improve the structural strength of the inner liner 200 and reduce the deformation of the inner liner 200 during the volume change process of the phase change media.

[0141] Strengthening the spacing of the crossbeams 410 can reinforce different locations of the inner liner 200, improving the overall structural strength of the inner liner 200 and reducing the risk of deformation.

[0142] In some embodiments of this application, the reinforcing crossbeam 410 is a frame structure, and the reinforcing crossbeam 410 is arranged horizontally around the outer periphery of the inner liner 200.

[0143] The reinforcing crossbeam 410 is installed around the outer periphery of the inner liner 200, which can reinforce the periphery of the inner liner 200 and prevent bulging and denting in the unreinforced areas around the inner liner 200.

[0144] In some embodiments of this application, the bottom of the outer casing 100 is provided with a support foot, which is connected to the fixed base 700 by a support member 710. There are at least two support members 710, and each support member 710 includes a support bottom, a support upright formed on both sides of the support bottom and perpendicular to the support bottom, and a support horizontal formed on each support upright. The support bottom is detachably connected to the fixed base 700, and the outer support foot is detachably connected to the support horizontal.

[0145] Specifically, the support bottom, support uprights, and support horizontals are integrally formed structures. The support bottom is provided with connecting holes, which are elongated holes to avoid connection errors.
