Description

Technical Field

[0001] The invention belongs to the technical field of air-conditioning boxes, and in particular relates to a novel composite thermal insulation box board for air-conditioning boxes. Background Art

[0002] The air-conditioning unit box panel has developed from the traditional frame structure to a frameless structure, achieving advantages such as lower air leakage rate, more energy saving, and significantly improved assembly efficiency.

[0003] At present, due to structural limitations, the existing market frameless air-conditioning box panels are all made of polyurethane foam. When the inner temperature of the air-conditioning box panel is greater than 60°C, the polyurethane foam will shrink and deform. The only option is to use a frame structure plus a rock wool handmade board structure. However, such a structure has low installation efficiency and high air leakage rate. Summary of the invention

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: a new type of composite insulation box panel for an air-conditioning box, which includes an inner panel, an outer panel, a first frameless panel frame profile, a second frameless panel frame profile, a plurality of panel reinforcement ribs, a rock wool insulation layer and a polyurethane insulation layer, the rock wool insulation layer is laid on the polyurethane insulation layer, the inner panel is attached to the rock wool insulation layer, the outer panel is attached to the polyurethane insulation layer, the first frameless panel frame profile and the second frameless panel frame profile are respectively clamped to the opposite ends of the polyurethane insulation layer and the opposite ends of the outer panel, the opposite ends of the inner panel are connected to the first frameless panel frame profile and the second frameless panel frame profile, a plurality of panel reinforcement ribs are penetrated into the rock wool insulation layer and the polyurethane insulation layer, and a plurality of panel reinforcement ribs connect the inner panel and the outer panel.

[0006] As a further description of the above technical solution:

[0007] The first frameless panel frame profile and the second frameless panel frame profile are both provided with slots, and the opposite ends of the outer panel are respectively inserted into the two slots.

[0008] As a further description of the above technical solution:

[0009] The inner panel is connected to the first frameless panel frame profile and the second frameless panel frame profile via a heat insulation strip.

[0010] As a further description of the above technical solution:

[0011] The panel reinforcement ribs are U-shaped light steel keels.

[0012] As a further description of the above technical solution:

[0013] The polyurethane thermal insulation layer is provided with two protrusions, and the protrusions wrap the side surfaces of the rock wool thermal insulation layer.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] In the present invention, the inner layer is a rock wool insulation layer combined with the inner panel, the outer layer is a flame retardant polyurethane insulation layer combined with the outer panel, the polyurethane insulation layer and the rock wool insulation layer are tightly combined and wrapped, and the panel reinforcement ribs are embedded inside. This ensures the strength of the panel, the flatness of the outside, the strong sealing, and the ability to withstand high temperatures above 90°C inside. It also meets the A-level fire protection requirements as a whole and has high installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
