Description

Technical Field

[0001] This utility model belongs to the field of air conditioning packaging technology, and in particular relates to a box panel and a panel air conditioning unit box. Background Technology

[0002] Air handling units, also known as air conditioning units or air handling boxes, mainly consist of a casing and various internal air handling functional sections. Their primary function is to process air for cleanliness, temperature, humidity, harmful gases, and noise before delivering it to air-conditioned rooms. In recent years, due to the explosive growth of commercial real estate and the industrial economy, air handling units have been widely used. Among the existing air handling unit casing structures, one type uses a frame-plate structure. This involves inserting various aluminum alloy profiles (frames, middle frames, tees, etc.) to form a casing frame, which is then fastened with fasteners to form an external or internal casing frame. Polyurethane foam wall panels (or rock wool foam wall panels) are then embedded into the frame and secured with appropriate fasteners. Finally, decorative strips and sealing strips are inlaid. The advantages of this type of box structure are: simple structure, single wall panel, and high wall panel foaming efficiency; however, it also has some obvious disadvantages: complex box assembly and low assembly efficiency; large amount of aluminum alloy is used, resulting in high box cost; the sheet materials (color plate, back panel) require cutting, corner cutting, bending and other processes, which inevitably generates waste and the utilization rate of sheet materials is low.

[0003] Another type is the pure panel enclosure structure with aluminum alloy edge strips. This type of enclosure has no aluminum alloy frame; the enclosure is formed solely by splicing together wall panels with aluminum alloy edge strips. Its characteristic is that the aluminum alloy edge strips and inner and outer panels are directly foamed and molded as a single unit. These wall panels have aluminum alloy profiles with male (or female) grooves embedded around their perimeter. During assembly, the male and female aluminum alloy profiles around the perimeter of the wall panels interlock, and then are tightened with rivet nuts and bolts to form the enclosure of the air handling unit. The advantages of this enclosure structure are: the enclosure consists only of wall panels, making assembly simple; the enclosure has no aluminum alloy frame, resulting in relatively less aluminum alloy usage; and the inner and outer wall panels only require cutting, not bending, leading to high material utilization. This type of aluminum alloy pure panel enclosure structure also has some obvious shortcomings: First, the wall panel foaming process is complex, and the wall panel requires high precision; second, this type of enclosure cannot withstand high positive pressure inside the enclosure because the inner and outer panels are not embedded with aluminum alloy edge strips and are not fixed with fasteners. The inner and outer panels are only bonded by foam material, which makes them prone to expansion under high positive pressure; third, this type of enclosure uses aluminum alloy profile edge strips around the wall panels, and the cost of aluminum alloy material for making foamed wall panels is relatively high. Summary of the Invention

[0004] This utility model provides a box panel and a panel air conditioning unit box to solve the problems mentioned in the background art, such as high box material cost and complex foaming process.

[0005] One technical solution of this utility model is as follows: A box panel includes: a side strip, a front panel, a back panel, and foam material. The side strip includes a first support, a second support, and a connecting strip. The first support and the second support are respectively vertically arranged at one end of the upper side and the other end of the lower side of the connecting strip. A first slot is vertically formed on the first support, and a second slot is vertically formed on the second support. Both sides of the front panel are provided with first folded edges, and the first folded edges of the front panel are inserted into the first slots. Both sides of the back panel are provided with second folded edges, and the second folded edges of the back panel are inserted into the second slots. Foam material is filled between the front panel and the back panel.

[0006] Furthermore, the number of edge strips is four, and the four edge strips form a frame structure by interlocking corners.

[0007] Furthermore, the edge strip is provided with a material injection port.

[0008] Furthermore, the panel, back panel, and edge strip are fixed with self-tapping screws.

[0009] Furthermore, the edge strip is made of PVC material.

[0010] Furthermore, the insert is made of ABS material.

[0011] Another technical solution of this utility model is as follows: a panel air conditioning unit housing, comprising six housing panels as described above, wherein the edge strips of adjacent housing panels are spliced ​​together to form a six-sided housing structure and the adjacent housing panels are fixed by self-tapping screws.

[0012] Furthermore, sealing strips are provided between the edge strips of adjacent box panels.

[0013] The beneficial effects of this utility model are:

[0014] 1. The enclosure is directly assembled from stepped foamed wall panels, without the frame made of aluminum alloy profiles such as borders, middle frames, and tees. The enclosure panels do not use aluminum alloy profile edge strips but instead use embedded plastic profiles, thus significantly reducing the cost of enclosure materials.

[0015] 2. When making the box panel, the outer frame of the wall panel is directly connected by PVC profile edge strips and ABS corner pieces, and then the inner and outer sheet metal panels are embedded to form the enclosure structure and then directly foamed. This wall panel structure has a simple foaming process, does not require positioning and clamping devices during foaming, and has high foaming efficiency.

[0016] 3. The enclosure is directly assembled from stepped enclosure panels. Adjacent enclosure panels are connected and fastened together by drilling a row of self-drilling self-tapping screws at designated positions using the same method. This ensures that the sheet metal back panels and sheet metal front panels of all the enclosure panels are securely connected, resulting in better strength for this type of enclosure assembled from pure wall panels.

[0017] 4. Since the sheet metal back panel and sheet metal front panel are separated by PVC profiles and foam material, the inner and outer sheet metal do not come into direct contact, so there is no cold bridge phenomenon in the enclosure.

[0018] 5. The stepped wall panel has three contact surfaces. When assembled into a box, the three surfaces are in close contact. The stepped vertical surface is covered with a sealing strip. This three-sided sealed box has a good sealing effect. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] In one technical solution of this utility model, Figure 1 and Figure 2 This is a structural diagram illustrating the specific structure of a box panel according to this utility model, as shown below. Figure 1 and Figure 2 As shown, the present invention includes: a side strip 2, a panel 1, a back panel 4, and a foam material 5. The side strip 2 includes a first support 21, a second support 22, and a connecting strip 33. The first support 21 and the second support 22 are respectively vertically arranged at one end of the upper side and the other end of the lower side of the connecting strip 33, so that the side strip 2 presents a stepped shape.

[0025] The first support 21 has a first slot vertically formed, the second support 22 has a second slot vertically formed, the panel 1 has a first folded edge on both sides, the first folded edge of the panel 1 is inserted into the first slot, the back plate 4 has a second folded edge on both sides, the second folded edge of the back plate 4 is inserted into the second slot, and foam material 5 is filled between the panel 1 and the back plate 4.

[0026] The number of edge strips 2 is four, and the four edge strips 2 form a frame structure by interlocking corners 3.

[0027] The edge strip 2 is provided with a material injection port 8.

[0028] The panel 1, back plate 4 and edge strip 2 are fixed by self-tapping screws 7.

[0029] The edge strip 2 is made of PVC material.

[0030] The insertion angle 3 is made of ABS material.

[0031] The foamed box panel consists of four stepped PVC profile side strips, four ABS corner pieces, one folded sheet metal panel, one corresponding folded sheet metal back panel, and polyurethane foam material.

[0032] During the fabrication of the foamed enclosure panels, four stepped PVC profile strips are first joined together using four ABS corner pieces to form a rectangular frame. Then, the corresponding folded edges of the front and back panels are embedded into the first and second slots of the strips, forming the enclosure structure. Finally, an injection hole is made in the middle of one of the PVC profile strips. The sealed enclosure structure is placed on a foaming table, and polyurethane foam is injected through the foaming agent injection hole, completing the foaming process. The finished foamed wall panels are then cleaned and used to assemble the enclosure.

[0033] In another technical solution of this utility model, Figure 3 and Figure 4 This is a structural diagram illustrating the specific structure of a panel air conditioning unit housing according to this utility model, as shown below. Figure 3 and Figure 4 As shown, including

[0034] The six box panels described above are joined together by the edge strips of adjacent box panels to form a six-sided box structure, and the adjacent box panels are fixed by self-tapping screws.

[0035] Sealing strips are installed between the edge strips of adjacent box panels.

[0036] The enclosure of this invention is formed by directly splicing together six enclosure panels without using aluminum alloy profiles. Specifically, during the splicing of the enclosure panels, a 1mm thick sealing strip is adhered to the inner surface of the steps of adjacent enclosure panels. Then, self-drilling self-tapping screws (7) are drilled into the designated positions to connect and secure the front and back panels of adjacent wall panels into a single unit. This ensures that the back panels of all wall panels constituting the enclosure are firmly connected, guaranteeing the enclosure's airtightness and mechanical strength. Because the front and back panels are separated by PVC profile edge strips and foam material, the inner and outer sheet metal do not directly contact each other, avoiding cold bridging.

[0037] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
