Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning unit housings for modular air conditioning units, and specifically relates to a housing. Background Technology

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners (such as stand-alone units or VRV systems), this system centrally processes air to achieve comfort requirements. The heating system provides the necessary heat to the air conditioning system to offset the indoor heat load. The heating principle of a central air conditioning system is as follows: the compressor draws in low-pressure gas, compresses it into high-temperature, high-pressure gas, and then the high-temperature gas passes through a heat exchanger to raise the water temperature. At the same time, the high-temperature gas condenses into a liquid, which then enters the evaporator for evaporation. After passing through the evaporator, the liquid becomes low-pressure, low-temperature gas, which is then drawn in by the compressor for compression. This cycle continues, and the circulating water on the air conditioning side becomes hot water at around 45-55 degrees Celsius. The hot water is then piped to the rooms that need heating. Fan coil units are installed in the rooms to exchange heat between the hot water and the air to achieve the heating purpose. The insulated and sealed box is an important component of the central air conditioning system for delivering heat.

[0003] Patent CN222747471U discloses a fully sheet metal bending interlocking high-sealing and heat-insulating box body, comprising several outer panels, which are spliced ​​together to form a square outer box body; several inner panels, which are positioned corresponding to the outer panels, and a sealing and heat-insulating mechanism is provided between the inner and outer panels. The sealing and heat-insulating mechanism includes a sealing strip, a heat insulation plate, and a rubber layer. Two symmetrically distributed heat insulation plates are movably provided at the inner ends of the outer panels, and a sealing strip is provided between two adjacent heat insulation plates. One end of each heat insulation plate is spliced ​​to an inner panel. A cavity is formed between the inner panels, the heat insulation plates in contact with the inner panels, and the inner sides of the outer panels in contact with the heat insulation plates. The cavity is filled with a rubber layer. A connecting component is provided between two adjacent outer panels. This utility model facilitates the connection and assembly between the box panels, allows for repeated disassembly and disassembly of the box body, and increases the sealing and heat insulation performance of the box body.

[0004] The aforementioned patented box structure employs a two-step design; please refer to the appendix of the patent. Figure 5 Furthermore, the irregularly shaped panels also have two steps, which makes the structure longer. However, since irregularly shaped panels are made of sheet metal, they are more prone to bending after becoming longer, which can lead to instability after installation. Utility Model Content

[0024] This utility model provides, for example Figure 1-5 The box shown includes

[0025] The main body consists of six sheet metal panels 1 spliced ​​together to form a square box. The splicing method is to fix the sheet metal panels 1 together with bolts 7 to form a square box. The inside of the square box is hollow. At the bend of the outer panel 2, a reinforcement 8 is placed to fit against its inner wall. The reinforcement 8 is also made of sheet metal and its shape matches the bend. The reinforcement 8 at the upper and lower ends of the outer panel 2 does not have rivet nuts 6. The reinforcement 8 at the middle ends of the outer panel 2 is equipped with rivet nuts 6. In this way, the upper and lower ends of the outer panel 2 are fixed to the middle outer panel 2 with bolts 7. Specifically, the bolts 7 pass through the reinforcement 8 from the outside of the outer panel 2 and connect with the rivet nuts 6 on the reinforcement 8 of the middle outer panel 2 to complete the fixation.

[0026] Both the upper and lower parts are made of two plates 1 spliced ​​in parallel. After the two plates 1 are spliced, the closer ends are recessed inward to form a groove. A foam board segment connector 4 is placed in the groove of the upper part. A rivet nut 6 is set on the reinforcement 8 of the two plates 1 at the position of the foam board segment connector 4. The two plates 1 are fixed by connecting the foam board segment connector 4 and the rivet nut 6 in the plate 1 with bolts 7. A connector 9 is placed in the groove of the lower part, and a rivet nut 6 is set on the connector 9. The bolts 7 pass through the outer plate 2 from the outside of the outer plate 2 and fix the two plates 1 to the rivet nut 6 on the connector 9.

[0027] The sheet material 1 includes an outer panel 2 and an inner panel 3, both of which are sheet metal parts. The two ends of the outer panel 2 are bent inwards, and after bending, both ends are inserted into the outer panel slots 53 of the two foamed insulation profiles 5. The two ends of the inner panel 3 are directly inserted into the inner panel slots 51 of the two foamed insulation profiles 5. The inner panel slots 51 and the outer panel slots 53 are located on different sides. Thus, the sheet material 1 forms a cavity structure composed of the outer panel 2, the inner panel 3, and the foamed insulation profiles 5. For the specific structural shape, see [reference needed]. Figure 1 This is just one embodiment. A rubber layer can be provided inside the cavity. The rubber layer is not existing technology. For details, please refer to patent number 202421269171.X. The foamed board heat insulation profile 5 is a step 52 located at the outer plate slot 53. In this way, during installation, the outer plate 2, the connector 9 or the foamed board segment connector 4 fits against the step 52.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
