[0031] like Figure 1As shown, this embodiment provides a housing assembly including a cylindrical shell 100, a first shell member 200, a second shell member 300, and a connecting assembly 400. The cylindrical shell 100 has a tubular structure; the first shell member 200 and the second shell member 300 are installed at both ends of the cylindrical shell 100; the connecting assembly 400 includes a threaded member 410 and an intermediate member 420. The threaded member 410 connects the first shell member 200 and the second shell member 300, and the intermediate member 420 abuts against the first shell member 200 and the second shell member 300 at both ends, respectively. The intermediate member 420 limits the minimum distance between the first shell member 200 and the second shell member 300. The intermediate member 420 and the threaded member 410 are independent components.
[0032] The first shell 200 and the second shell 300 are connected to each other by a threaded component 410, which limits and fixes the end caps to both ends of the cylindrical shell 100. The intermediate component 420 is located between the first shell 200 and the second shell 300, with its two ends abutting against the first shell 200 and the second shell 300 respectively. During the process of operating the threaded component to reduce the distance between the first shell 200 and the second shell 300, the gap between the first shell 200 and the second shell 300 will not shrink indefinitely. When they get close to each other to a certain extent, the first shell 200 and the second shell 300 will be close to both ends of the cylindrical shell 100. At this time, the first shell 200 and the second shell 300 will touch the two ends of the intermediate component, and thus the distance between the first shell 200 and the second shell 300 cannot be reduced further, preventing the first shell 200 and the second shell 300 from squeezing the cylindrical shell 100 due to excessive distance, which would cause the cylindrical shell 100 to deform. The threaded part 410 and the intermediate part 420 are set up and processed independently, which can reduce the number of processing steps and lower the cost. In some embodiments, the threaded part 410 and the intermediate part 420 can even be purchased as standard parts to reduce costs.
[0033] like Figure 1As shown, in some embodiments, the first shell 200 has a first fixing block 210, and the second shell 300 has a second fixing block 310. The first fixing block 210 and the second fixing block 310 correspond to each other. A threaded component 410 connects and installs the first fixing block 210 and the second fixing block 310. An intermediate component 420 limits the movement of the first fixing block 210 and the second fixing block 310. The first fixing block 210 is disposed on the edge of the first shell 200, and the second fixing block 310 is also disposed on the edge of the second shell 300. A connecting component 400 is disposed between the first fixing block 210 and the corresponding second fixing block 310. Multiple first fixing blocks 210 and second fixing blocks 310 are provided around the first shell 200 and the second shell 300, and multiple connecting components 400 are disposed between multiple first fixing blocks 210 and second fixing blocks 310, fixing the first shell 200 and the second shell 300 to both ends of the cylindrical shell 100. The arrangement of multiple connecting components 400 around the first shell 200 and the second shell 300 can make the first shell 200 and the second shell 300 be subjected to uniform force, and make the fixation between the first shell 200, the second shell 300 and the cylindrical shell 100 more balanced and stable.
[0034] like Figure 1 As shown, in some embodiments, the first fixing block 210 and the second fixing block 310 have smooth through holes that mate with the threaded component 410. The threaded component 410 is used to install the first fixing block 210 and the second fixing block 310 at both ends of the cylindrical shell 100 via nuts 411. The nuts 411 are installed on the threaded component 410. The threaded component 410, through the smooth through holes, enables the first shell component 200 and the second shell component 300 to be connected in series. The nuts 411 are screwed into the threaded component 410 from one end, thereby limiting the positioning of the first shell component 200 and the second shell component 300, placing them at both ends of the cylindrical shell 100. As the nuts 411 are gradually screwed in, the gap between the first shell component 200 and the second shell component 300 becomes smaller and smaller until the first shell component 200 and the second shell component 300 are fixed at both ends of the cylindrical shell 100, thus achieving the purpose of fixing the first shell component 200 and the second shell component 300 at both ends of the cylindrical shell 100. The method of fixing by screwing the nut 411 into the threaded part 410 has strong adaptability. Since the specifications of the threaded part 410 are relatively fixed, when assembling cylindrical shells 100 of different lengths, the screwing distance of the nut 411 can be adjusted to adapt to the assembly of different cylindrical shells 100.
[0035] like Figures 1 to 4As shown, in some embodiments, the threaded component 410 is configured as a bolt, and the second fixing block 310 has a positioning groove 311 that mates with the nut 411 of the threaded component 410; when the housing assembly is installed, the nut 411 of the threaded component 410 can be embedded in the positioning groove 311. The bolt is a standard part, and the nut 411 is placed in the positioning groove 311. The bolt is inserted through the first fixing block 210 and screwed into the nut 411 in the second fixing block 310, connecting the first housing component 200 and the second housing component 300. As the bolt is gradually screwed in, the gap between the first housing component 200, the second housing component 300 and the cylindrical shell 100 gradually decreases until the first housing component 200 and the second housing component 300 are tightly attached to both ends of the cylindrical shell 100. Since the nut 411 is embedded in the positioning groove 311, when it is necessary to separate the first housing component 200, the second housing component 300 and the cylindrical shell 100, they can be separated by rotating the bolt. The bolts are standard parts, which can be directly purchased during production, eliminating the need for bolt processing and reducing costs. The first shell 200 and the second shell 300 are installed by fixing with nuts 411 and screwing in bolts. The assembly and disassembly of the shell components can be completed by operating only the bolts, which can save on the assembly tools required in production and thus save costs.
[0036] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, in some embodiments, the threaded component 410 is configured as a screw with threads at both ends, and both ends of the threaded component 410 mate with nuts 411. When the housing assembly is installed, the nuts 411 install the first fixing block 210 and the second fixing block 310 at both ends of the cylindrical shell 100. The screw passes through the smooth through holes of the first fixing block 210 and the second fixing block 310, and the nuts 411 are screwed in from both ends of the screw towards the middle, fixing the first housing component 200, the second housing component 300, and the cylindrical shell 100 together. Compared with using bolts, the method of using nuts 411 to screw the first housing component 200 and the second housing component 300 from both ends towards the middle of the screw to limit their position, and simultaneously using nuts at both ends to fasten them, provides a more uniform clamping force and stronger load-bearing capacity because the nuts at both ends participate in the load-bearing, thus preventing the intermediate objects from loosening or displacing under vibration or external force.
[0037] like Figures 1 to 4 As shown, in some embodiments, the first fixing block 210 and the second fixing block 310 have grooves 211 that mate with the intermediate member 420, and both ends of the intermediate member 420 are installed in the grooves 211. The mating installation of both ends of the intermediate member 420 in the grooves 211 can effectively fix the intermediate member 420 and prevent the intermediate member 420 from shifting during installation and use, which would lead to limit failure.
[0038] like Figures 1 to 4As shown, in some embodiments, the intermediate component 420 is tubular. A tubular intermediate component 420 uses less material, is less expensive, lighter, and easier to transport compared to a solid intermediate component 420.
[0039] like Figures 1 to 4 As shown, in some embodiments, the threaded component 410 is inserted into the intermediate component 420. The threaded component 410 needs to be installed in corresponding through holes on the first fixing block 210 and the second fixing block 310, and the intermediate component 420 needs to be installed in the groove 211 that mates with it. By inserting the threaded component 410 into the intermediate component 420, and similarly, by setting the through holes of the first fixing block 210 and the second fixing block 310 in the groove 211 that mates with the intermediate component 420, the area occupied by the through holes and the groove 211 on the first fixing block 210 and the second fixing block 310 can be reduced, thereby reducing the volume of the first fixing block 210 and the second fixing block 310, reducing the material used for the first fixing block 210 and the second fixing block 310, and thus reducing the production cost of the housing assembly.
[0040] like Figures 1 to 4 As shown, in some embodiments, the first shell 200 and the second shell 300 have slots 312, and a sealing strip 313 is provided in the slots 312; the cylindrical shell 100 is inserted into the slots 312 and abuts against the sealing strip 313. The edges of the first shell 200 and the second shell 300 have slots 312. Before the connecting assembly 400 is installed, both ends of the cylindrical shell 100 are inserted into the slots 312 to achieve positioning between the cylindrical shell 100 and the first shell 200 and the second shell 300. After the connecting assembly 400 is installed, the ends of the cylindrical shell 100 abut against the sealing strip 313 in the slots 312, so that a sealed environment is formed inside the cylindrical shell 100, reducing heat loss during product use.
[0041] like Figures 1 to 6 As shown, this utility model also provides a heat exchanger, including a shell assembly of any of the above embodiments. When the heat exchanger using the above shell assembly is installed, the first shell member 200 and the second shell member 300 are connected and fixed to both ends of the cylindrical shell 100 by threaded members 410. The intermediate member 420 is located between the first shell member 200 and the second shell member 300 to prevent the first shell member 200 and the second shell member 300 from pressing the cylindrical shell 100 due to being too close, which would cause the cylindrical shell 100 to deform. The threaded member 410 and the intermediate member 420 are independently set and independently processed, which can reduce the processing steps and lower the cost. In some embodiments, the threaded member 410 and the intermediate member 420 can even be purchased as standard parts to reduce costs.
[0042] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
