[0002] Currently, the existing air handling unit housing structure (referred to as heat exchange housing) is usually formed by welding multiple complex plates. The welded heat exchange housing structure has the following main disadvantages: 1. Welding quality affects overall performance; if the welding process is not handled properly, welding defects such as cracks, pores, and lack of fusion may occur. These problems will directly affect the sealing and strength of the housing, and may even lead to water leakage; 2. High processing and installation complexity; welding usually requires specialized welding equipment and skills, which may increase time and cost in the production process. Furthermore, on-site welding of large enclosures may be limited by site constraints, making the installation process more complex; 3. Maintenance and repair are difficult; once a problem occurs in a part of the enclosure and welding repair is required, not only are suitable welding conditions and environments needed, but the repair process may also damage the original integrity and sealing, causing greater losses; 4. Material and structural limitations; welding is suitable for metallic materials, but for non-metallic materials or thin-plate metallic materials, welding may not be applicable or may easily cause material damage; in addition, some complex structures or thin-walled structures may deform during welding, affecting the final assembly accuracy and performance; 5. Low flexibility; enclosures formed by welding are difficult to disassemble and reassemble, which means that when design changes are made or internal components need to be replaced, at least a part of the enclosure may need to be reprocessed, reducing the flexibility and upgradeability of use.

[0003] Therefore, the existing welded heat exchanger box structure has problems such as cumbersome processing and assembly, low production efficiency, and inconvenience for subsequent maintenance and upgrades. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a heat exchange box structure, including: a plurality of sheet metal parts 10 and a plurality of connecting parts; at least a portion of the plurality of sheet metal parts 10 has a bent edge 17, and the bent edge 17 on one sheet metal part 10 is detachably connected to an adjacent sheet metal part 10 through a connecting part; the plurality of sheet metal parts 10 surround to form at least a portion of the heat exchange box structure, and the surrounding space forms a receiving cavity for accommodating heat exchange equipment.

[0033] This invention, by using multiple sheet metal parts 10 and multiple connectors, makes the heat exchanger box structure easier to assemble and disassemble, facilitating subsequent maintenance and upgrades, while also reducing potential quality problems and safety risks caused by welding. The use of bent edges 17 in conjunction with the connectors not only facilitates reliable connection between thin sheet metal parts 10 but also enhances the sealing and stability of the box structure. The use of multiple sheet metal parts 10 further reduces processing difficulty and costs. Furthermore, the use of sheet metal parts 10 avoids the material and structural limitations of welding, allowing the sheet metal parts 10 to be made of non-metallic materials or thin metal sheets. When the heat exchanger box structure needs to be disassembled and reassembled, no reprocessing is required; only the corresponding connectors need to be removed, thus improving usability. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of cumbersome processing and assembly, low production efficiency, and inconvenience for subsequent maintenance and upgrades in existing heat exchanger box structures, making it suitable for large-scale promotion and use.

[0034] It should be noted that, in a specific embodiment of this utility model, sheet metal part 10 refers to a part processed from metal sheet (commonly known as sheet metal) through processes such as shearing, stamping, bending, stretching, and welding. Sheet metal, as a common form of metal processing, has wide applications in manufacturing. The following details some key features and processing steps of sheet metal part 10 in this utility model: Basic properties of sheet metal: Thickness: The thickness of sheet metal is usually relatively uniform, typically between 0.5mm and 6mm, but thicker or thinner products can be made according to application requirements; Material: Commonly used sheet metal materials include, but are not limited to, stainless steel, galvanized steel sheet, aluminum sheet, and copper sheet. Each material is suitable for different application scenarios due to its physical and chemical properties; Surface treatment: To prevent corrosion, improve aesthetics, or enhance the specific performance of the parts, sheet metal part 10 often undergoes surface treatment after processing, such as painting, anodizing, and plating. Processing steps of sheet metal part 10: Shearing: The metal sheet is cut according to the dimensions and shape of the design drawings using a shearing machine or laser cutting equipment. Stamping: Applying pressure to metal sheets using molds and presses to deform them into the desired shape, enabling operations such as bending, forming, and punching. Bending: Bending sheet metal materials along straight or curved lines using a bending machine to form the required geometric shapes and structures. Stretching: With the assistance of specific molds, applying tension allows the material to extend in a plane or space, forming complex curved shapes. Welding: Using methods such as electric welding, argon arc welding, and laser welding, multiple sheet metal parts 10 are connected together to form an integral structure. Surface Treatment and Painting: The processed sheet metal parts 10 undergo surface cleaning, anti-corrosion treatment, and painting to meet appearance and functional requirements; compared to castings or forgings, sheet metal parts 10 are generally lighter, helping to reduce the overall weight of equipment; in mass production, the cost of sheet metal parts 10 is relatively low because of their fast processing speed and the ability to reduce material waste through optimized design; sheet metal parts 10 can also be formed into various complex shapes according to design requirements, providing a high degree of design freedom; through reasonable design and processing, sheet metal parts 10 can achieve high strength and rigidity, meeting the needs of practical use.

[0035] In one specific embodiment of the present invention, in at least a portion of the sheet metal parts 10, two adjacent sheet metal parts 10 are detachably and fixedly connected by at least one connector.

[0036] like Figure 1 and Figure 2 As shown, the heat exchange box structure also includes a base 20, which is disposed at the lower part of the heat exchange box structure; the plurality of sheet metal parts 10 include a plurality of vertically arranged sheet metal parts 10, at least a portion of the plurality of vertically arranged sheet metal parts 10 are respectively disposed around the base 20 and are detachably connected to the base 20.

[0037] Using the base 20 as a support and fixing foundation, the box structure is constructed through detachable sheet metal parts 10, which facilitates the overall movement and installation of the box. The above design makes the installation and movement of the heat exchange box structure more flexible, reduces installation and transportation costs, and improves the deployment efficiency of the equipment. Practical application scenarios include occasions where heat exchange equipment needs to be moved between different locations, such as temporary buildings and mobile air conditioning systems. This design can meet the needs of rapid deployment and flexible adjustment of the equipment.

[0038] like Figure 1 As shown, the heat exchange box structure also includes a water receiving tray 30, which is disposed on the base 20 and located at the bottom of the receiving cavity. The water receiving tray 30 is used to receive condensate in the receiving cavity; and / or, the base 20 has a limiting groove, which is used to limit and cooperate with the sheet metal part 10 disposed on the base 20.

[0039] By setting up a water collection tray 30 to collect condensate generated during the heat exchange process, the condensate is prevented from directly contacting the heat exchange equipment, thus preventing corrosion and damage. The setting of the limiting groove not only increases the installation strength of the sheet metal parts 10 set on the base 20, but also facilitates the quick positioning and installation of the sheet metal parts 10 on the base 20. This setting also improves the waterproof performance of the heat exchange box structure and the service life of the equipment, and reduces maintenance costs. Practical application scenarios include all heat exchange equipment that needs to handle condensate, such as air conditioning systems, industrial cooling systems, etc., especially in high humidity environments, this design can effectively protect the heat exchange equipment and avoid failures caused by condensate.

[0040] like Figure 1 and Figure 2 As shown, the water receiving tray 30 is inclined relative to the horizontal plane towards the bottom wall of the receiving cavity to guide the condensate to flow in a directional manner under the action of gravity; and / or, the heat exchange box structure also includes a drain pipe 40, one end of which is connected to the outside and the other end is connected to the water receiving tray 30, and the drain pipe 40 is used to drain the condensate collected in the water receiving tray 30.

[0041] By utilizing gravity and the inclined bottom wall design of the drip tray 30, condensate is guided to the drain pipe 40, achieving automatic condensate discharge. The implementation effect of the above design is to improve the condensate discharge efficiency, reduce the risk of condensate accumulation in the tank, and improve the operational safety and efficiency of the equipment. Practical application scenarios include all heat exchange equipment that requires efficient condensate discharge, such as air conditioning systems in high humidity environments and industrial cooling systems that require continuous operation. This design can ensure that the equipment can effectively discharge condensate under any operating conditions, avoiding equipment failure caused by condensate accumulation.

[0042] like Figure 1As shown, the heat exchanger box structure also includes a support bracket 50 for installing the heat exchange equipment. The lower part of the support bracket 50 is fixedly installed on the bottom wall of the water receiving pan 30 facing the interior of the receiving cavity, and the upper part is used to support the heat exchange equipment so that the heat exchange equipment is spaced apart from the condensate in the water receiving pan 30; and / or, the heat exchanger box structure also includes an insulation layer 60. The insulation layer 60 is made of insulation material, and at least one side of the water receiving pan 30 has an upwardly folded edge 31. A portion of the insulation layer 60 is sealed and fitted with the folded edge 31 and the sheet metal part 10 respectively.

[0043] The heat exchange equipment is isolated from the condensate in the water receiving pan 30 by the support bracket 50. At the same time, the heat loss during the heat exchange process is reduced and the heat exchange efficiency is improved by the sealing cooperation of the insulation layer 60 and the folded edge 31. This configuration improves the thermal efficiency of the heat exchange box structure, reduces the energy consumption of the equipment, and improves the economic and environmental performance of the equipment. The above design can significantly improve the heat exchange performance and energy efficiency of the equipment, reduce operating costs, and reduce the impact on the environment.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, multiple sheet metal parts 10 include a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, and a top plate 15.

The first side plate 11 and the third side plate 13 are spaced apart and correspond to each other, and the second side plate 12 and the fourth side plate 14 are spaced apart and correspond to each other. The top plate 15 is disposed on the first side plate 11. 1. The top of the second side plate 12, the third side plate 13 and the fourth side plate 14, and detachably connected to at least one of the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 via a connector; wherein, the plurality of sheet metal parts 10 further include a maintenance plate 16, the receiving cavity having a maintenance port communicating with the outside, the maintenance plate 16 being disposed at the maintenance port for opening and closing the maintenance port; the maintenance plate 16 being detachably connected to at least one of the first side plate 11, the fourth side plate 14 and the top plate 15 via a connector.

[0045] The main structure of the heat exchanger enclosure is constructed using the first side plate 11, the second side plate 12, the third side plate 13, the fourth side plate 14, and the top plate 15. A maintenance panel 16 is also provided to facilitate inspection and maintenance of the enclosure's interior. This design improves the ease of maintenance and upgradeability of the heat exchanger enclosure, reduces maintenance costs and downtime, and enhances equipment availability and maintenance efficiency. Practical applications include heat exchange equipment requiring regular inspection and maintenance, such as air conditioning systems and industrial cooling systems. Especially in space-constrained environments, the maintenance panel 16 provides sufficient maintenance space without affecting normal equipment operation.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, the heat exchanger box structure also includes an adjusting bolt 70 and a fastener 80. The adjusting bolt 70 is threaded into one of the first side plate 11, the fourth side plate 14, and the top plate 15. The fastener 80 is disposed on the adjusting bolt 70. The adjusting bolt 70 presses the fastener 80 against the outer surface of the inspection plate 16 to fix the inspection plate 16.

[0047] The maintenance plate 16 can be quickly fixed and disassembled by adjusting the combination of bolt 70 and fastener 80. A handle 90 is provided for easy opening of the maintenance plate 16, and the ventilation holes ensure airflow inside and outside the enclosure, improving heat exchange efficiency. This design improves the fixing efficiency and opening convenience of the maintenance plate 16, reduces maintenance costs and downtime, and enhances the thermal efficiency of the heat exchange enclosure structure, reducing energy consumption during equipment operation.

[0049] By using a first and second filter, the incoming and outgoing airflow is filtered to prevent dust and impurities from entering, thus protecting the normal operation of the heat exchange equipment. This design improves the cleanliness of the heat exchange chamber structure and the operational stability of the equipment, reducing the equipment failure rate and maintenance costs. Practical applications include all heat exchange equipment that requires protection from dust and impurities, such as cooling systems for electronic equipment and air handling systems for food processing. This design ensures that the equipment maintains good operating conditions in any environment, extends its service life, and reduces maintenance costs.

[0050] like Figure 1 and Figure 5 As shown, the heat exchange box structure also includes an insulation layer 60, which is made of insulation material. At least a portion of the insulation layer 60 is pasted and fixed to at least a portion of the sheet metal parts 10 facing the inner wall of the receiving cavity, for the purpose of insulating the receiving cavity; and / or, at least a portion of the insulation layer 60 is disposed between two adjacent sheet metal parts 10 for sealing the gap between the two adjacent sheet metal parts 10.

[0051] By incorporating the insulation layer 60, heat loss during heat exchange is reduced, improving heat exchange efficiency. Simultaneously, the bends 17 and connectors enhance the sealing and stability of the enclosure structure. This design improves the thermal efficiency of the heat exchange enclosure structure and the operational stability of the equipment, reduces energy consumption and maintenance costs, and enhances the equipment's economic and environmental performance.

[0054] The heat exchanger 100 and the fan assembly 110 work together to achieve efficient heat exchange and circulation of air. Meanwhile, the inlet pipe 101 and outlet pipe 102 ensure the normal operation of the heat exchanger 100. This design improves the heat exchange efficiency and operational stability of the air handling unit, reduces energy consumption and maintenance costs, and enhances its economic and environmental performance.

[0055] The specific working process and principle of one embodiment of this utility model will now be described in detail as follows:

[0056] Insulation material can be adhered to the sheet metal parts 10 surrounding the heat exchanger box structure to form an insulation layer 60, such as... Figure 5 As shown, the sheet metal part 10, the insulation layer 60, and the water receiving tray 30 are pressed and sealed together; the water receiving tray 30 is integrally welded, resulting in better overall strength; the heat exchanger box structure uses sheet metal + insulation cotton material to achieve sealing and heat insulation effects. The sheet metal part 10 has a simple structure, as shown... Figure 1 As shown, apart from the water tray 30, the heat exchange box structure uses only five sheet metal parts 10, which is convenient to assemble; the inspection plate 16 adopts a bolt + fastener 80 fixed sealing method, which is convenient to disassemble and assemble, solving the problems of poor sealing in traditional methods and the easy stripping of screws due to repeated disassembly and assembly when directly fixed with screws; the water tray 30 is inclined relative to the horizontal plane towards the bottom wall of the cavity, and has at least one inclined angle to promote the flow and rapid discharge of condensate.

[0057] Furthermore, existing air handling unit enclosures have significant shortcomings in terms of drainage, sealing, and structural simplicity.

Furthermore, the use of multiple sheet metal parts 10 further reduces processing difficulty and lowers costs. The cost is reduced. In addition, by using sheet metal parts 10, the material and structural limitations of welding are avoided, allowing the sheet metal parts 10 proposed in this utility model to be made of non-metallic materials or thin metal sheets. When the heat exchanger box structure needs to be disassembled and reassembled, no reprocessing is required; only the corresponding connecting parts need to be disassembled, thereby improving the flexibility of use.
