Description

Technical Field

[0001] This application relates to the technical field of heat exchangers, and particularly to a heat exchanger with a splicing type Rubik's Cube structure. Background Art

[0002] Under the limitations of processing capabilities and the limited size of single plates, a strategy of modular production needs to be adopted for manufacturing large-area plate heat exchangers. First, a detailed heat exchanger design is carried out to determine the required heat transfer area and performance indicators. Due to the limited area of a single plate, designers need to decompose the overall heat transfer area into multiple smaller modules. According to the processing capabilities, decide how to divide these modules. Usually, the heat exchanger will be divided into several modules of similar size to facilitate subsequent production and assembly, determine the processing sequence and process route for each module. Considering the size and complexity of the modules, it may be necessary to carry out processing and assembly in stages to ensure that each module meets the design requirements. At each production stage, strict quality control and process monitoring are carried out to ensure that the dimensional accuracy and quality of each module meet the design requirements. After all modules are manufactured, an overall finished product inspection is carried out. This includes checking key indicators such as welding quality, sealing performance, and heat transfer efficiency to ensure that the overall heat exchanger can meet the usage requirements and standards of customers.

[0003] However, in the case of a single heat exchanger with a large heat load and a large heat transfer area, there are the following problems: Large-sized heat exchangers require a larger welding and assembly space, and the size and weight of a single unit may exceed the handling capacity of conventional workplaces. This will make the welding and assembly processes more complex and may require special equipment and a longer cycle to complete the manufacturing. The huge volume and weight of a single heat exchanger may limit the transportation methods and handling operations, and special transportation tools and additional safety measures may be required during transportation, increasing the transportation cost and safety risks. It is more difficult to ensure the consistency and unity of each part in a heat exchanger manufactured integrally. For example, there may be greater fluctuations in welding quality, sealing performance, and material stress distribution in a large-sized structure, affecting the final quality and reliability of the product. Installing a large heat exchanger on-site may be restricted by space, especially around existing equipment or buildings. This will increase the complexity and adjustment workload during the installation process and may require customized solutions to adapt to the actual on-site situation. Summary of the Utility Model

[0004] Therefore, this application provides a heat exchanger with a splicing type Rubik's Cube structure to solve the problems of high installation space requirements, high installation complexity, long production cycle, insufficient product quality and reliability, and difficult transportation existing in large-sized fully welded heat exchangers in the prior art.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A detachable heat exchanger with a Rubik's Cube structure includes multiple heat exchanger modules. Each heat exchanger module includes a core body and a peripheral frame. The core body is composed of multiple heat exchange plates arranged and stacked in sequence. A stabilizer for strengthening all the heat exchange plates in the core body is provided on each core body. The peripheral frame wraps around the outside of the core body and the stabilizer to form a frame structure.

[0007] Optionally, the stabilizer includes multiple fixing blocks. Adjacent two heat exchange plates are spaced apart by the fixing blocks, and both sides of the fixing blocks are in contact with the adjacent two heat exchange plates respectively.

[0008] Optionally, the stabilizer includes a comb-shaped plate. The protruding teeth of the comb-shaped plate correspond one by one to the heat exchange plates, and each protruding tooth is located between two adjacent heat exchange plates.

[0009] Optionally, the distance between two adjacent protruding teeth matches the thickness of the heat exchange plates.

[0010] Optionally, the stabilizer includes a fixing cross bar which is fixed on the outside of the two outermost heat exchange plates.

[0011] Optionally, the stabilizer includes a positioning cross bar. The length direction of the positioning cross bar is consistent with the arrangement direction of the heat exchange plates. The positioning cross bar is fixed at the corner of the core body and is fixed to the heat exchange plates.

[0012] Optionally, multiple stabilizers are symmetrically provided on the core body.

[0013] Optionally, each heat exchanger module includes multiple core bodies, and the peripheral frame wraps multiple core bodies inside.

[0014] Optionally, multiple heat exchanger modules are spliced by welding.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] Manufacturing a detachable heat exchanger in modules, decomposing an all-welded heat exchanger into multiple heat exchanger modules can simplify the complexity of on-site installation. Especially when the equipment needs to be installed in a limited space, this flexibility is particularly important. In addition, the production processes of multiple heat exchanger modules can be processed in parallel, shortening the overall production cycle. Each heat exchanger module can be independently processed and assembled on a specially designed workstation, reducing production delays caused by the busyness of a single large device. Each heat exchanger module can be inspected under special quality control steps to ensure that the welding quality, material strength and structural stability meet the design requirements, improving the overall quality and reliability of the product. Moreover, by decomposing into heat exchanger modules, the size and weight of individual components can be reduced, simplifying the transportation and loading processes and reducing the risk of damage during transportation.

[0023] The following further details the present application through specific embodiments in conjunction with the drawings.

[0024] In the description of the present application: Unless otherwise specified, "a plurality of" means two or more. Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0025] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in the present application are generally indications of the general relative positional relationship for the convenience of intuitively understanding with reference to the drawings, and are not absolute limitations on the positional relationship in the actual product.

[0026] A Rubik's cube structure spliceable heat exchanger, referring to Figures 1-3 , includes a plurality of heat exchanger modules 1, and a complete heat exchanger can be spliced by welding the plurality of heat exchanger modules 1.

[0027] Each heat exchanger module 1 is composed of one or more cores 4 and a peripheral frame 2. Each core 4 is formed by stacking and welding a plurality of heat exchange plates 3 in sequence to increase the heat exchange area. In this embodiment, in order to improve the overall strength of the core 4, a stabilizer is provided on each core 4 for strengthening all the heat exchange plates 3 inside the core 4. The peripheral frame 2 wraps around the outside of the core 4 and the stabilizer to form a frame structure, which is used to support and connect multiple cores 4, provide structural support for the entire heat exchanger module 1, and provide integration and connection points during multi-module assembly.

[0028] In one embodiment, the stabilizer includes a plurality of fixing blocks 5. Two adjacent heat exchange plates 3 are spaced apart by one fixing block 5, and both sides of the fixing block 5 are in contact with the two adjacent heat exchange plates 3 respectively. The fixing block 5 is used to support the heat exchange plates 3 to ensure the stability and reliability of the internal structure of the core 4 and improve the overall strength.

[0029] In another embodiment, the fixing block 5 can be replaced with a comb-shaped plate 6, and either one can be used. The number and position of the protruding teeth of the used comb-shaped plate 6 correspond to those of the heat exchange plates 3 one by one, so that each protruding tooth can be located between two adjacent heat exchange plates 3, and the distance between two adjacent protruding teeth is adapted to the thickness of the heat exchange plates 3, so that the protruding teeth can support the heat exchange plates 3.

[0030] In the specific implementation process, multiple groups of the fixing blocks 5 or the comb-shaped plates 6 can be arranged at intervals along the height direction of the heat exchange plates 3 to fix the heat exchange plates 3 at different positions.

[0031] Furthermore, the stabilizer also includes a fixing cross bar 7. The fixing cross bar 7 is fixed on the outside of the two outermost heat exchange plates 3 and serves as a part of the support structure to help the core 4 maintain its overall shape and stability, especially in the vibration and pressure environments that may be faced during the operation of the equipment.

[0032] A plurality of fixing cross bars 7 are arranged along the height direction of the heat exchange plates 3, and the number and position correspond to those of the fixing blocks 5 or the comb-shaped plates 6, and then they are connected together by welding to achieve a better support effect.

[0033] For the convenience of production, the stabilizer also includes a positioning cross bar 8. The length direction of the positioning cross bar 8 is the same as the arrangement direction of the heat exchange plates 3, and the positioning cross bar 8 is respectively arranged at the four corners of the core 4, that is, the left and right sides of the upper and lower ends of the plate bundle. The positioning cross bar 8 is fixed to the heat exchange plates 3 and is used to fix and position the position of the plate bundle and the outer dimensions of the core 4 to compensate for the dimensional errors during the forming process of the heat exchange plates 3.

[0034] In the embodiment of the present application, in order to improve the overall stability of the core 4, the stabilizers are symmetrically arranged on the core 4.

[0035] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be considered as falling within the scope described in this specification.
