Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning cold-break bridges, and in particular relates to a cold-break bridge air-conditioning box frame structure. Background Art

[0002] Cold bridge breaking technology is an important measure to save energy and improve efficiency in air conditioning systems. It mainly involves the thermal insulation performance of the air conditioning box, and by cutting off the path of cold transfer, it reduces the loss of cold and energy and improves the energy efficiency of the air conditioning system.

[0003] The frame structure of the cold-break bridge air-conditioning box is usually composed of a rectangular structural profile and a straight plug-in. The straight plug-in has a plug, and after the plug is plugged into the rectangular structural profile, it is fixed by screws. Figure 4 The existing 40x80cm rectangular structural profile is shown, which is composed of two outer frame materials 1 and two cold-breaking connecting plates 2, wherein the two corners of the outer frame material 1 form a frame 11 for plugging with a straight plug-in, and the straight plug-in is connected to the frame 11 by screws. Such a structure will form a closed loop between the high-pressure section and the low-pressure section in the air-conditioning box. At the same time, due to the existence of the corner frame, the cold-breaking connecting plate 2 is shorter and cannot effectively cut off the cold transfer, and the area occupied by the internal insulation filler is smaller, resulting in poor insulation performance, and condensation is easily formed on the air-conditioning box in summer. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, a cold-bridge air-conditioning box frame structure is provided.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A frame structure of an air-conditioning box with an insulated cold bridge comprises a rectangular structural profile and a straight plug-in, wherein the straight plug-in has a plug, the plug is plugged into the rectangular structural profile and fixed by screws, and is characterized in that the rectangular structural profile comprises two horizontal plates and two vertical insulated cold connecting plates, the two horizontal plates are arranged in parallel front to back, the insulated cold connecting plates are shorter than the horizontal plates, and the two insulated cold connecting plates are arranged in parallel left to right between the two horizontal plates, the four together form a rectangle, and a heat-insulating filler is provided in the cavity formed by the insulated cold bridge, the inner sides of both ends of the horizontal plates are provided with a card slot, and the two ends of the insulated cold connecting plates are respectively provided with a card portion, the card portion is carded with the corresponding card slot, and a socket for plugging with the plug is formed on the heat-insulating filler.

[0007] The utility model provides a rectangular structural profile of a frame structure of an air-conditioning box with an insulated cold bridge, which is formed by two horizontal plates and two vertical insulated cold connecting plates. Compared with the existing rectangular structural profiles of the same specification, the horizontal plates are used to replace the original outer frame materials. On the one hand, the area of ​​the heat insulating filler is increased, and the heat insulating performance is improved. When connected with the straight plug-in, the screws are directly driven into the heat insulating filler, which can avoid the connection between the high-pressure section and the low-pressure section of the air conditioner. On the other hand, the length of the insulated cold connecting plate is increased, which can effectively cut off the cold transfer, so that condensation is not easy to form on the air-conditioning box in summer.

[0012] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0013] like Figure 1 As shown, an embodiment of the present application provides a cold bridge air conditioning box frame structure, including a rectangular structural profile 100 and a straight plug-in 200.

[0014] The rectangular structural profile 100 has a specification of 40x80cm, such as Figure 2 As shown, it includes two horizontal plates 110 and two vertical cold-insulating connecting plates 120 .

[0015] The two horizontal plates 110 are arranged in parallel front and back, the cold-breaking connecting plate 120 is shorter than the horizontal plate 110, and the two cold-breaking connecting plates 120 are arranged in parallel left and right between the two horizontal plates 110. The four together form a rectangle, and the cavity formed by the enclosed is provided with an insulating filler 130, such as a polyurethane foam filler.

[0016] The transverse plate 110 is made of aluminum alloy, and has slots on the inner sides of both ends thereof. In this embodiment, the slots are dovetail slots.

[0017] In order to improve the strength and to provide screw holes, the two ends of the cross plate 110 are thicker, with a thickness of 2.5 mm, while the middle section is relatively thinner, with a thickness of 1.8 mm.

[0018] The cold-insulating connecting plate 120 is made of ABS plastic material, and has a clamping portion 121 at both ends, and the clamping portion 121 is clamped with the corresponding clamping slot. Figure 1 As shown, taking the left side cold-break connecting plate 120 as an example, the upper clamping portion 121 thereof is clamped with the left clamping slot of the upper horizontal plate 110 , and the lower clamping portion 121 is clamped with the left clamping slot of the lower horizontal plate 110 .

[0019] like Figure 4 As shown, in the existing rectangular structural profile, there is a gap A between the two outer frame materials 1, which causes a bite with the adjacent plate during installation. In order to overcome this problem, in this embodiment, the cold-breaking connecting plate 120 is located between the corresponding ends of the two horizontal plates 110, and the two ends of the cold-breaking connecting plate 120 are bent inwardly to form a clamping portion 121 respectively. Such a structure can avoid the formation of a gap between the two horizontal plates 110.

[0020] Preferably, the outer surface of the cold-insulating connecting plate 120 is flush with the end surface of the corresponding end of the transverse plate 110 .

[0021] like Figure 1 As shown, taking the left side cold-break connecting plate 120 as an example, it is located between the left side ends of the two transverse plates 110 , and its outer surface is flush with the end surfaces of the left side ends of the two transverse plates 110 .

[0022] like Figure 1-3 As shown, the straight plug 200 is made of ABS plastic material, which includes a rectangular plate 210. The front of the rectangular plate 210 forms a plug 220. The plug 220 is tubular. In order to improve the strength, a reinforcing plate 222 is provided inside the plug 220, so that the radial cross-section of the plug 220 is in the shape of a Japanese character. Accordingly, a socket for plugging with the plug 220 is formed on the thermal insulation filler 130. After the two are plugged in, they are fixed by screws, and the screws are directly driven into the thermal insulation filler.

[0023] like Figure 2 As shown, in this embodiment, the outer circumference of the plug 220 is adapted to the inner circumference of the cavity where the thermal insulation filler 130 is located, so that after the plug 220 is inserted into the socket, most of its outer circumference is in contact with the inner circumference of the cavity, thereby improving the stability of the plug-in.

[0024] like Figure 2As shown, the four corners of the outer peripheral surface of the plug 220 respectively have arc grooves 221 extending along the length direction of the plug and concave inward, and the slope of the arc groove 221 is 1.5-2 degrees, so that the connection between the straight plug 200 and the rectangular structural profile 100 is more secure.

[0025] like Figure 1 and Figure 3 As shown, the middle of the long side of the rectangular plate 210 has a connecting plate 211 perpendicular to it, and the connecting plate 211 has two fixing screw holes for connecting and fixing with other components of the cold bridge air conditioning box, such as connecting and fixing with the corners of the cold bridge air conditioning box.

[0026] It can be seen from the above that the rectangular structural profile of the cold-break bridge air-conditioning box frame structure provided in the embodiment of the present application is formed by two horizontal plates and two vertical cold-break connecting plates. Compared with the existing rectangular structural profiles of the same specification, horizontal plates are used instead of the original outer frame materials. On the one hand, the area of ​​the thermal insulation filler is increased and the thermal insulation performance is improved. When connecting with the straight plug-in, the screws are directly driven into the thermal insulation filler to avoid the connection between the high-pressure section and the low-pressure section of the air conditioner. On the other hand, the length of the cold-break connecting plate is increased, which can effectively cut off the cold transfer, so that condensation is not easy to form on the air-conditioning box in summer.

[0027] In addition, the position of the cold-break connecting plate can avoid the formation of gaps between the two horizontal plates and prevent the occurrence of biting.

[0028] Obviously, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
