Technical Field
[0001] The utility model belongs to the technical field of air-conditioning cold-break bridges, and in particular relates to a square structural profile of a cold-break bridge air-conditioning box. 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 square structural profile is one of the components of the cold-break bridge air-conditioning box. Figure 2 The figure shows an existing 40x40cm square structural profile, which consists of an outer frame material 1, two cold-breaking connecting plates 2 and a corner frame material 3, wherein the cold-breaking connecting plates 2 are relatively short and cannot effectively cut off the cold transfer, and there is a gap A between the outer frame material 1, the two cold-breaking connecting plates 2 and the corner frame material 3, so that the area occupied by the thermal insulation filler inside the outer frame material 1 is relatively small, resulting in poor thermal insulation performance. Utility Model Content
[0004] Based on this, in order to solve the above technical problems, a square structural profile of a cold-break bridge air-conditioning box is provided.

[0007] The square structural profile of the cold-break bridge air-conditioning box provided by the utility model is composed of an outer plate, two cold-break connecting plates and corner pieces.

[0010] 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.
[0011] like Figure 1 As shown, the embodiment of the present application provides a square structural profile of a 40x40cm in size thermal insulation bridge air-conditioning box, including an outer plate 110, two thermal insulation connecting plates 120 and a corner piece 130.
[0012] The cross-section of the outer panel 110 is L-shaped, the two cold-breaking connecting plates 120 are parallel to the horizontal and vertical sections of the outer panel 110, the corner pieces 130 are arranged diagonally to the corners of the outer panel 110, and the four together form a square. The cavity formed by the enclosed is provided with an insulating filler 111, such as a polyurethane foam filler.
[0013] The outer plate 110 is made of aluminum alloy, and has first slots on the inner sides of both ends thereof.
[0014] In order to improve the strength, the thickness of the two ends of the outer plate 110 is greater than the thickness of the remaining parts thereof, and the thickness is further increased at the position where the first slot is set.
[0015] The cold-insulating connecting plate 120 is made of ABS plastic material, and has a first clamping portion 121 and a second clamping portion 122 at both ends thereof. The first clamping portion 121 is clamped with the corresponding first clamping slot. Figure 1 As shown, taking the horizontal cold-break connecting plate 120 as an example, the first clamping portion 121 at the right end thereof is clamped with the first clamping groove on the inner side of the vertical section of the outer plate 110 .
[0016] The angle piece 130 is made of aluminum alloy and has two second clamping grooves that are respectively clamped with the second clamping parts 122 of the corresponding cold-insulating connecting plates 120 .
[0017] Specifically, the corner piece 130 includes an L-shaped outer contour plate 131 opposite to the corner of the outer plate 110 and an L-shaped inner contour plate 132 connected to the L-shaped outer contour plate 131. The horizontal section and the vertical section of the L-shaped inner contour plate 132 respectively form second card grooves. Taking the horizontal cold-break connecting plate 120 as an example, the second card portion 122 at its left end is card-engaged with the second card groove on the vertical section of the L-shaped inner contour plate 132.
[0018] like Figure 2 As shown, in the existing structural profiles, there is a gap B between the corner frame material 3 and the outer frame material 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 end of the L-shaped outer contour plate 131 of the corner piece 130 and the corresponding end of the outer plate 110. The two ends of the cold-breaking connecting plate 120 are bent inwardly to form a first clamping portion 121 and a second clamping portion 122 respectively. Such a structure can avoid the formation of a gap between the L-shaped outer contour plate 131 and the outer plate 110.
[0019] Preferably, the outer surface of the cold-insulating connecting plate 120 is flush with the outer surface of the corresponding section of the L-shaped outer contour plate 131 and the end surface of the corresponding end of the outer plate 110 .
[0020] Taking the transverse cold-breaking connecting plate 120 as an example, it is located between the end of the transverse section of the L-shaped outer contour plate 131 and the end of the vertical section of the outer plate 110. The outer side surface of the cold-breaking connecting plate 120 is flush with the outer surface of the transverse section of the L-shaped outer contour plate 131 and the end face of the vertical section of the outer plate 110.
[0021] Wherein, the first card slot and the second card slot are both dovetail slots.
[0022] From the above, it can be seen that the square structural profile of the cold-break bridge air-conditioning box provided in the embodiment of the present application is composed of an outer panel, two cold-break connecting plates and corner pieces. Compared with the existing square structural profiles of the same specification, the length of the cold-break connecting plate is increased, which can effectively cut off the transfer of cold air, and the area of the insulating filler is also increased, thereby improving the thermal insulation performance.
[0023] In addition, the position of the cold-break connecting plate can avoid gaps between the outer plate and the corner fittings, preventing the occurrence of bite.
[0024] 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.
