It is applicable to air conditioning systems with a resistance greater than 100 Pa. In recent years, with the accelerated development of fields such as medicine, semiconductors, lithium batteries, transportation tracks, and electronic factories, the combined air handling unit has also found new application scenarios. However, the requirements of these new scenarios often come with high air volume, high static pressure, high air quality, etc. This requires the air conditioning box to have strong mechanical strength, good sealing performance, and heat insulation performance.

The internal corners of the combined box body are designed in a right-angle shape. In high-end purification applications, the filter device and the corners of the unit are cleaned regularly.

[0045] In some embodiments of the present application, the heat insulation part 320 is a heat insulation cavity formed on the connecting member 300, and the inside of it is filled with polyurethane foam to achieve the heat insulation effect.

[0046] The rigid support 330 is assembled on the insertion part 310 to enhance the strength of the connecting member 300.

[0051] In some embodiments of the present application, the locking component is a locking screw, which passes through the panel and is locked and fixed on the rigid support 330 to connect the panel component 200 and the connecting member 300 together.

[0052] Through the provided rigid support member 330, not only the strength of the entire connecting member 300 is enhanced, but also the connection between the panel member 200 and the connecting member 300 is achieved.

[0053] In the combined air conditioner unit of this embodiment, adjacent panel members 200 are connected by a connecting member 300. The connecting member 300 uses a plastic member, and the plastic member has a low thermal conductivity, which can achieve a good heat insulation effect. On one side of the connecting member 300 close to the inner space of the box body, a heat insulation part 320 is formed. The heat insulation part 320 can achieve the heat insulation effect. Through the double cooperation of the plastic member and the heat insulation part 320, the overall heat insulation effect is ensured. Moreover, in this embodiment, the box body of the combined air conditioner unit adopts a structural mode of a plastic member cooperating with a rigid support member 330, which greatly reduces the cost on the basis of ensuring the structural strength.

[0056] In some embodiments of the present application, the connecting member 300 includes: A connecting body 350, with inclined portions 351 arranged obliquely on both sides. The inclined portions 351 are inclined surfaces formed on both sides of the connecting body 350, and a heat insulation cavity is formed inside the connecting body.

[0057] And a strengthened connecting portion 360 connected to the bottom of the connecting body 350, and a clamping portion 370 is formed between the strengthened connecting portion 360 and the connecting body 350.

[0058] The insertion portion 310 is formed by enclosing between the strengthened connecting portion 360 and the connecting body 350.

[0059] When arranging the rigid support member 330, it can be embedded in the strengthened connecting portion 360, or arranged along the inner side surface or the outer side surface of the strengthened connecting portion 360.

[0060] The clamping portion 370 is formed on the outer side surface at the connection position between the connecting body 350 and the strengthened connecting portion 360. It is a clamping groove, and the clamping groove is an arc-shaped clamping groove or a semi-circular clamping groove with one side open.

[0061] In some embodiments of the present application, the panel member 200 includes: an inner panel member 210, which is a rigid member, and a lower bending arm is formed above it; an outer panel member 220, which is a rigid member, and an upper bending arm is formed above it. The length of the outer panel member 220 is greater than that of the inner panel member 210.

[0062] a plastic heat insulation member 230, arranged around the inner panel member 210 and the outer panel member 220, and a filling cavity is formed between the plastic heat insulation member 230 and the inner panel member 210 and the outer panel member 220. Foaming material is arranged in the filling cavity; The plastic heat insulation member 230 includes: a plastic body 231, which has a mating inclined portion 232 adapted to the inclined portion 351; the mating inclined portion 232 is a mating inclined surface adapted to the inclined surface. When the connecting member 300 is arranged between the panel members 200, the inclined surface and the mating inclined surface are attached.

[0063] a protruding portion 233, extending outward from the bottom of the plastic body 231. The lower bending arm on the outer panel member 220 wraps around the outside of the protruding portion 233 to ensure the strength of the plastic heat insulation member 230.

[0067] When the connecting member 300 is assembled between two panel members 200, its inclined surface above is attached to and presses the mating inclined surface to squeeze the first flexible sealing protrusion 234 on the mating inclined surface to achieve a better sealing effect.

[0068] A second flexible sealing protrusion 235 is arranged below the first flexible sealing protrusion 234 and is arranged obliquely for being clamped in the clamping portion 370.

[0069] During assembly, the second flexible sealing protrusion 235 can be clamped in the clamping portion 370. Since the second flexible sealing protrusion 235 is arranged obliquely and is flexible, when the internal pressure of the box is less than the external pressure, it is pressed and fitted to the side of the clamping portion 370 close to the internal space of the box to achieve sealing; When the internal pressure of the box is greater than the external pressure, it is pressed tightly against the side of the clamping portion 370 away from the internal space of the box to achieve sealing, so as to ensure a good sealing effect regardless of whether the box is under positive pressure or negative pressure.

[0070] The plastic thermal insulation member 230 in this embodiment is made of PVC, and can be integrally formed through an extrusion process during molding. During molding, the hardness of the plastic member body 231 is made greater than the first flexible sealing protrusion 234 and the second flexible sealing protrusion 235, which not only ensures the structural strength of the panel component 200 surrounded by the plastic thermal insulation member 230, but also ensures the first flexible sealing protrusion 234 and the second flexible sealing protrusion 235 have a flexible sealing effect.

The cooperation of the three-layer sealing structure ensures the sealing effect between the two. Since the sealing structure is formed by the plastic insulation part 230 and the structure of the connecting member 300 itself, there is no need to perform gluing and sealing between the panel component 200 and the connecting member 300, which solves the problem of low production efficiency of gluing and sealing in existing combined air-conditioning units and greatly improves the production efficiency of the line.

[0072] In some embodiments of the present application, the connecting member 300 is a connecting frame, which is connected at the butt joint of two mutually perpendicular panel components 200 .

[0073] The box body is composed of a top panel component 200, a bottom panel component 200 and a side panel component 200, and the connecting frame is arranged at the docking position of any adjacent and mutually perpendicular panel components 200.

The three plug-in protrusions can be respectively inserted into the plug-in parts 310 of three connecting frames that intersect at a corner to connect the three, and a sealing gasket is arranged at the connection position of the plug-in tee and the connecting frame.

[0077] In some embodiments of the present application, the insertion portion 310 is an insertion cavity, and the insertion protrusion is inserted into the insertion cavity.
