[0015] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clear and explicit, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0016] As shown in Figures 1-14 , an air conditioner heat preservation plate structure comprises a heat insulation profile 1 and a support frame 8, the opening of the heat insulation profile 1 is spliced into a rectangular frame through a plastic foot plug 2; A panel assembly is inserted into the rectangular frame, the panel assembly is filled with heat preservation material 6, the heat preservation material adopts high-density foamed polyurethane material, and double-layer sealing design is realized to reduce the air leakage rate of the box body; The heat insulation profile 1 is fixedly connected with the support frame 8 through a fastener 10, and a second sealing strip 7 is installed between the opposite surfaces of the heat insulation profile 1, the plastic foot plug 2 and the support frame 8, so as to ensure the sealing performance between the heat insulation profile 1, the plastic foot plug 2 and the support frame 8.

[0017] Specifically, the heat insulation profile 1 is made of polymer material and is formed by extrusion molding process into a W-shaped plastic strip with a panel insertion slot in the cross section, which facilitates the insertion of the inner panel or the outer panel. At the same time, the heat insulation profile can ensure that the edge of the panel is not easily in contact with the air, thereby preventing the panel from rusting. Furthermore, a rectangular cavity is provided on the inner side wall of one end of the heat insulation profile 1, which can play a role in strengthening the support. Furthermore, the size of the panel insertion slot that plugs into the inner panel is larger than the size of the panel insertion slot that plugs into the outer panel, and the panel insertion slot that plugs into the outer panel is designed with a beveled edge to facilitate plugging into the outer panel. The plastic pin 2 is an L-shaped plastic part with two pins, formed by injection molding of polymer material. The plastic insulation profiles and plastic feet are not only easy to process and manufacture, but also form thermal bridges to prevent heat transfer between the inner and outer panels, thus ensuring the insulation effect.

[0018] Specifically, the panel assembly includes an inner panel 3 and an outer panel 5. The four sides of the inner panel 3 are bent upwards and then outwards to form a lidless box-like structure with flange edges. The four sides of the outer panel 5 are bent in the same direction to form a lidless box-like structure, and a through hole is provided on the outer panel 5. A hole cover 9 is installed at the opening of the through hole. The edges of the inner panel 3 and the outer panel 5 are fastened to the panel insertion slot.

[0019] Specifically, a first sealing strip 4 is provided between the outer panel 5 and the opposite surface of the rectangular frame, and the first sealing strip 4 ensures the sealing performance between the outer panel and the rectangular frame.

[0020] An assembly process for an air conditioning insulation panel structure includes the following steps: Step 1, such as Figures 1-2 As shown, the three thermal insulation profiles are connected into a U-shaped structure using two plastic feet. Step 2, as follows Figures 3-4 As shown, insert the three flange edges of the inner panel into the U-shaped panel insertion slot; Step 3, as follows Figures 5-6 As shown, connect the other two plastic feet to the openings at both ends of another thermal insulation profile, and then insert this assembly into the remaining flange edge of the inner panel to form a rectangular structure. Step 4, as follows Figures 7-8 As shown, a sealing frame is attached to the rectangular structure formed by the plastic profile and plastic feet; Step 5, as follows Figures 9-10 As shown, the outer panel is fastened into the panel insertion slot to form a hollow, closed box-shaped assembly with inner and outer panels, and the outer panel abuts against the sealing frame. Step 6: Drill injection holes on the inner panel, and then use an integrated polyurethane foaming process to form the core. Step 7: Apply a sealing strip to each of the two stepped surfaces of the thermal insulation profile for sealing with the box frame.

[0021] Through steps one through seven, an air conditioning unit panel with two sealing effects, thermal break bridges, and rust-resistant inner edges is formed.
