[0062] The inventors of this application have discovered that current air conditioning units do not completely isolate the heat transfer path between the inside and outside, resulting in cold bridges and poor insulation performance.

[0065] like Figures 1 to 10 As shown, the anti-cold bridge housing for air conditioning units in this embodiment includes: an aluminum alloy profile frame 1, a tee 2, and an insulation panel 3.

[0066] The two ends of the aluminum alloy profile frame 1 are connected to the tee 2 respectively. Multiple aluminum alloy profile frames 1 and multiple tee 2 are spliced ​​and assembled to form a rectangular frame. The tee 2 is located at the top corner of the rectangular frame.

[0067] The aluminum alloy profile frame 1 includes: a first aluminum alloy outer frame 11, a first aluminum alloy inner frame 12, and a first plastic heat insulation strip 13.

[0068] The first aluminum alloy outer frame 11 is L-shaped with right angles, including: a first straight side 111 and a second straight side 112, wherein the lengths of the first straight side 111 and the second straight side 112 are the same.

[0069] The first aluminum alloy inner frame 12 includes: a first frame 121 and a second frame 122.

[0070] The second frame 122 of the first aluminum alloy inner frame 12 is a rectangular frame, and there are two of them. The two second frame 122 are arranged perpendicular to each other, and the two second frame 122 are connected through the first frame 121.

[0071] The first straight edge 111 and the second straight edge 112 of the first aluminum alloy outer frame 11 are respectively connected to the first frame body 121 of the first aluminum alloy inner frame 12 through the first plastic heat insulation strip 13. The first straight edge 111 and the first plastic heat insulation strip 13 are arranged perpendicular to each other, and the second straight edge 112 and the first plastic heat insulation strip 13 are also arranged perpendicular to each other. The first straight edge 111, the second straight edge 112, the first plastic heat insulation strip 13 and the first frame body 121 form a square third frame body 123.

[0072] The first aluminum alloy outer frame 11 and the first aluminum alloy inner frame 12 are connected by two first plastic heat insulation strips 13 to form a thermally broken aluminum alloy profile frame 1. The first plastic heat insulation strips 13 isolate the heat transfer path between the first aluminum alloy outer frame 11 and the first aluminum alloy inner frame 12.

[0073] The insulation panel 3 has steps on all four sides.

[0074] During assembly, the two side walls of the insulation panel 3 abut against the first plastic heat insulation strip 13 of the aluminum alloy profile frame 1, and are fixed to the second frame body 122 of the first aluminum alloy inner frame 12 by fixing screws. The step of the insulation panel 3 abuts against the right-angle apex of the second frame body 122 of the first aluminum alloy inner frame 12. The insulation panel 3 closes the rectangular frame formed by splicing and assembling the aluminum alloy profile frame 1 and the tee 2.

[0075] The first plastic heat insulation strip 13 is made of PVC (polyvinyl chloride).

[0076] In this embodiment, the first aluminum alloy outer frame and the first aluminum alloy inner frame are connected by a first plastic thermal insulation strip. The first plastic thermal insulation strip isolates the thermal connection between the aluminum alloy outer frame and the aluminum alloy inner frame, effectively reducing heat transfer between them. The air conditioning unit is installed inside the casing and connected to the indoor unit through connecting pipes, which can effectively reduce the loss of cooling or heating capacity of the air conditioning unit, improve energy utilization efficiency, and reduce energy consumption.

[0077] As can be seen from the above, the anti-cold bridge enclosure for air conditioning units in this embodiment uses an aluminum alloy profile frame, a tee, and an insulation panel. The aluminum alloy profile frame and the tee are spliced ​​together to form a square frame. The aluminum alloy profile frame includes a first aluminum alloy outer frame, a first aluminum alloy inner frame, and a first plastic heat insulation strip. The first aluminum alloy outer frame includes a first straight side and a second straight side. The first aluminum alloy inner frame includes a first frame body and two second frame bodies. The first straight side and the second straight side are respectively connected to the first frame body by the first plastic heat insulation strip. The insulation panel is fixed to the second frame body, thus enclosing the square frame. In this embodiment, the anti-cold bridge enclosure for air conditioning units connects the first aluminum alloy outer frame to the first aluminum alloy inner frame through the first plastic heat insulation strip, forming a broken-bridge aluminum alloy profile frame. The first plastic heat insulation strip isolates the connection between the inner and outer aluminum alloy frames, blocking the path of heat conduction through the aluminum alloy profile frame, thereby reducing heat transfer, playing a role in heat insulation, improving the energy efficiency of the air conditioning system, and preventing condensation on the surface of the enclosure frame during air conditioning operation.

[0078] Optional, such as Figure 2 As shown, in this embodiment, the anti-cold bridge housing for the air conditioning unit has plug-in protrusions 131 at both ends of the first plastic heat insulation strip 13.

[0079] The first straight edge 111 and the second straight edge 112 of the first aluminum alloy outer frame 11 are each provided with a first insertion groove 101, and the first frame body 121 of the first aluminum alloy inner frame 12 are provided with a second insertion groove 102 on both sides.

[0080] The insertion protrusions 131 at both ends of the first plastic heat insulation strip 13 are respectively inserted into the first insertion groove 101 and the second insertion groove 102 to realize the connection between the first plastic heat insulation strip 13 and the first aluminum alloy outer frame 11, and the first plastic heat insulation strip 13 and the first aluminum alloy inner frame 12.

[0081] Optional, such as Figure 2 and Figure 3 As shown, in this embodiment, the anti-cold bridge housing for the air conditioning unit has a first sleeve 21, a second sleeve 22 and a third sleeve 23 on each connecting arm of the tee 2.

[0082] There are two second sleeves 22, which are arranged perpendicular to each other. The first sleeve 21 is located at the intersection of the two second sleeves 22. The first sleeve 21, the second sleeve 22 and the third sleeve 23 of the tee 2 are respectively adapted to the first frame 121, the second frame 122 and the third frame 123 of the aluminum alloy profile frame 1.

[0083] When the aluminum alloy profile frame 1 is connected to the tee 2, the first sleeve 21, the second sleeve 22 and the third sleeve 23 of the tee 2 are respectively fitted into the first frame body 121, the second frame body 122 and the third frame body 123 of the aluminum alloy profile frame 1, so as to realize the quick connection between the tee 2 and the aluminum alloy profile frame 1 and make the connection between the tee and the aluminum alloy profile frame more convenient.

[0084] Furthermore, in this embodiment, the anti-cold bridge housing for the air conditioning unit, the tee 2 includes: an outer frame 201 and an inner frame 202.

[0085] The inner frame 202 is mounted on the outer frame 201 and is located inside the outer frame 201.

[0086] The outer frame 201 of the tee 2 is made of zinc-aluminum alloy, and the third sleeve 23 of the tee 2 is set on the outer frame 201, that is, the third sleeve 23 of the tee 2 is made of zinc-aluminum alloy.

[0087] The inner frame 202 of the tee 2 is made of PVC plastic. The first sleeve 21 and the second sleeve 22 of the tee 2 are set on the inner frame 202, that is, the first sleeve 21 and the second sleeve 22 of the tee 2 are made of plastic.

[0088] In this embodiment, a combination of zinc-aluminum alloy and plastic materials is used for the tee, which increases the rigidity and strength of the tee, while blocking the heat conduction path at the tee, reducing the internal and external heat transfer at the tee, preventing cold bridges at the tee, and further improving the thermal insulation performance of the enclosure.

[0089] Furthermore, in this embodiment, the cold bridge prevention box for the air conditioning unit has insulation cotton 4 between the insulation panel 3 and the second frame 122 of the first aluminum alloy inner frame 12.

[0090] Optional, such as Figure 5 and Figure 6 As shown, the insulation panel 3 of the anti-cold bridge housing for the air conditioning unit in this embodiment includes: an outer panel 31, an inner panel 32, a plastic heat insulation insert 33, and a polyurethane foam layer 34.

[0091] The outer panel 31 has protruding mounting portions 311 around its perimeter, and the plastic heat insulation insert 33 is disposed within the protruding mounting portions 311 of the outer panel 31.

[0092] The plastic heat insulation insert 33 has a connecting slot on the side away from the outer panel 31, and the inner panel 32 has a protruding plug-in part 321. The protruding plug-in part 321 of the inner panel 32 is engaged in the connecting slot of the plastic heat insulation insert 33, so that the inner panel 32 is connected to the plastic heat insulation insert 33, while ensuring that the inner panel 32 and the outer panel 31 do not contact each other.

[0093] The outer panel 31 has foaming holes on its sidewalls. Polyurethane foaming agent is filled into the cavity formed by the outer panel 31, the inner panel 32 and the plastic heat insulation insert 33, forming a polyurethane foam layer 34 in the cavity.

[0094] In this embodiment, the insulation panel adopts a sandwich structure with two layers, and the outer and inner panels are steel plates, which are respectively connected to plastic thermal insulation plugs. The two panels do not contact each other, blocking the heat transfer path at the side wall of the insulation panel and reducing heat exchange between the inside and outside. This eliminates the occurrence of cold bridges.

[0095] Furthermore, in this embodiment, the insulation panel 3 of the anti-cold bridge housing for the air conditioning unit also includes: sheet metal inserts 35.

[0096] The plastic heat insulation insert 33 has receiving grooves on both its inner and outer sides, and two sheet metal inserts 35 are respectively inserted into the two receiving grooves of the plastic heat insulation insert 33.

[0097] In this embodiment, the sheet metal inserts increase the strength of the insulation panel itself, and during assembly, the fixing screws pass through the aluminum alloy profile frame and engage with the threaded holes of the sheet metal inserts, thereby increasing the connection strength of the fixing screws.

[0098] Optionally, the anti-cold bridge housing for the air conditioning unit in this embodiment further includes: an inspection door 5 and a central support 6.

[0099] The central support 6 is vertically installed on the square frame, and its upper and lower ends are connected to the aluminum alloy profile frame 1, respectively.

[0100] The access doors 5 are located on the left and right sides of the square frame. One side of the access door 5 is hinged to the central support 6, and the other side of the access door 5 is equipped with a door lock structure for locking the access door 5. The access doors 5 facilitate the inspection and maintenance of the air conditioning unit inside the unit.

[0101] Furthermore, such as Figure 8 , Figure 9 and Figure 10 As shown, the anti-cold bridge housing for the air conditioning unit in this embodiment includes a central support 6 comprising: a second aluminum alloy outer frame 61, a second aluminum alloy inner frame 62, and a second plastic heat insulation strip 63.

[0102] The second aluminum alloy outer frame 61 is plate-shaped and has insertion slots at both ends.

[0103] The second aluminum alloy inner frame 62 is rectangular and also has a plug-in slot.

[0104] The second plastic heat insulation strip 63 has plug-in protrusions at both ends, and its material is PVC.

[0105] The two ends of the second aluminum alloy outer frame 61 are connected to the second aluminum alloy inner frame 62 by the second plastic heat insulation strip 63, so that the middle support 6 also forms a thermally broken aluminum alloy profile frame structure, which blocks the heat transfer path at the middle support, reduces heat loss, and prevents cold bridges from occurring.

[0106] When the central support 6 is connected to the aluminum alloy profile frame 1, an adapter is set on the aluminum alloy profile frame 1, and the central support 6 is sleeved on the adapter of the aluminum alloy profile frame 1.

[0107] During assembly, the insulation panel 3 is fixed to the second aluminum alloy inner frame 62 of the central support 6, and the side wall of the insulation panel 3 abuts against the second plastic heat insulation strip 63.

[0108] Insulation cotton 4 is provided between the insulation panel 3 and the second aluminum alloy inner frame 62.

[0109] Furthermore, the anti-cold bridge housing for the air conditioning unit in this embodiment also includes: a channel steel base frame 7.

[0110] The channel steel base frame 7 is rectangular. The rectangular frame formed by splicing and assembling the aluminum alloy profile frame 1 and multiple tees 2 is set on the channel steel base frame 7, so that the anti-cold bridge box is set off from the ground, reducing the heat exchange between the box and the ground, and preventing ground moisture from damaging the box, such as causing corrosion or mold, thus extending the service life of the box.
