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

[0066] Both ends of the aluminum alloy profile frame 1 are connected to the tees 2 respectively. Multiple aluminum alloy profile frames 1 and multiple tees 2 are spliced and assembled to form a rectangular square frame. The tees 2 are located at the top corners of the square 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 in a right-angled L-shape, and includes a first straight side 111 and a second straight side 112 . The first straight side 111 and the second straight side 112 have the same length.

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

[0070] The second frame bodies 122 of the first aluminum alloy inner frame 12 are rectangular frames, and two second frame bodies 122 are provided. The two second frame bodies 122 are arranged perpendicular to each other and are connected by the first frame body 121 .

[0071] The first straight side 111 and the second straight side 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 thermal insulation strip 13, and the first straight side 111 and the first plastic thermal insulation strip 13 are arranged perpendicular to each other, and the second straight side 112 and the first plastic thermal insulation strip 13 are also arranged perpendicular to each other. The first straight side 111, the second straight side 112, the first plastic thermal 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 insulation strips 13 to form a thermally-insulated aluminum alloy profile frame 1 . The first plastic 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 side walls around the thermal insulation panel 3 are provided with steps.

[0074] When the insulation panel 3 is assembled, the side walls of the insulation panel 3 are abutted against the first plastic 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 is abutted against the right-angled top corner of the second frame body 122 of the first aluminum alloy inner frame 12. The insulation panel 3 closes the rectangular frame assembled by splicing the aluminum alloy profile frame 1 and the tee 2.

[0075] The first plastic heat-insulating 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 of the aluminum alloy profile frame are connected by a first plastic heat insulation strip. The first plastic heat insulation strip isolates the heat connection between the aluminum alloy outer frame and the aluminum alloy inner frame, effectively reducing the heat transfer between the aluminum alloy outer frame and the aluminum alloy inner frame. The air conditioner unit is installed in the box body and connected to the indoor unit through a connecting pipeline, which can effectively reduce the cold or heat loss of the air conditioner unit, improve the energy utilization efficiency, and reduce the energy consumption.

[0077] It is not difficult to find from the above content that for the cold-bridge prevention box body for the air conditioner unit in this embodiment, by setting the aluminum alloy profile frame, the tee joint and the heat preservation panel, the aluminum alloy profile frame and the tee joint are spliced into 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 edge and a second straight edge. The first aluminum alloy inner frame includes: a first frame body and two second frame bodies. The first straight edge and the second straight edge are respectively connected to the first frame body through the first plastic heat insulation strip. The heat preservation panel is fixed on the second frame body to enclose the square frame. For the cold-bridge prevention box body for the air conditioner unit in this embodiment, the first aluminum alloy outer frame is connected to the first aluminum alloy inner frame through the first plastic heat insulation strip to form a broken-bridge type aluminum alloy profile frame. The first plastic heat insulation strip isolates the connection between the inner and outer aluminum alloy frames, blocks the heat conduction path through the aluminum alloy profile frame, thereby reducing the heat transfer, playing a role in heat preservation and insulation, and improving the energy efficiency of the air conditioning system; and preventing the appearance of condensation on the surface of the box body frame during the operation of the air conditioner.

[0078] Optionally, as Figure 2 shown, for the cold-bridge prevention box body for the air conditioner unit in this embodiment, plug-in bumps 131 are provided at both ends of the first plastic heat insulation strip 13.

[0079] First plug-in slots 101 are provided at the ends of the first straight edge 111 and the second straight edge 112 of the first aluminum alloy outer frame 11, and second plug-in slots 102 are provided on both sides of the first frame body 121 of the first aluminum alloy inner frame 12.

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

[0081] Optionally, as Figure 2 and Figure 3 shown, for the cold-bridge prevention box body for the air conditioner unit in this embodiment, each connecting arm of the tee joint 2 is provided with a first sleeve 21, a second sleeve 22 and a third sleeve 23.

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

[0083] When the aluminum alloy profile frame 1 is connected to the three-way joint 2, the first sleeve 21, the second sleeve 22, and the third sleeve 23 of the three-way joint 2 are respectively sleeved inside the frame bodies of the first frame body 121, the second frame body 122, and the third frame body 123 of the aluminum alloy profile frame 1, realizing the quick connection between the three-way joint 2 and the aluminum alloy profile frame 1 and making the connection between the three-way joint and the aluminum alloy profile frame more convenient.

[0084] Furthermore, for the cold-bridge prevention box body for the air-conditioning unit in this embodiment, the three-way joint 2 includes: an outer frame body 201 and an inner frame body 202.

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

[0086] The material of the outer frame body 201 of the three-way joint 2 is zinc aluminum alloy. The third sleeve 23 of the three-way joint 2 is arranged on the outer frame body 201, that is, the material of the third sleeve 23 of the three-way joint 2 is zinc aluminum alloy.

[0087] The material of the inner frame body 202 of the three-way joint 2 is PVC plastic. The first sleeve 21 and the second sleeve 22 of the three-way joint 2 are arranged on the inner frame body 202, that is, the materials of the first sleeve 21 and the second sleeve 22 of the three-way joint 2 are plastic.

[0088] In this embodiment, the combined three-way joint made of zinc aluminum alloy material and plastic material not only increases the rigidity and strength of the three-way joint, but also blocks the heat conduction path at the three-way joint, reduces the internal and external heat transfer at the three-way joint, prevents the occurrence of cold bridges at the three-way joint, and further improves the heat preservation performance of the box body.

[0089] Furthermore, for the cold-bridge prevention box body for the air-conditioning unit in this embodiment, there is a heat preservation cotton 4 between the heat preservation panel 3 and the second frame body 122 of the first aluminum alloy inner frame 12.

[0090] Optionally, as Figure 5 and Figure 6 shown, for the cold-bridge prevention box body for the air-conditioning unit in this embodiment, the heat preservation panel 3 includes: an outer panel 31, an inner panel 32, a plastic heat insulation plug-in 33, and a polyurethane foam layer 34.

[0091] The outer panel 31 is provided with a protruding mounting portion 311 around its perimeter, and the plastic heat insulation plug-in 33 is arranged inside the protruding mounting portion 311 of the outer panel 31.

[0092] The plastic heat-insulating insert 33 is provided with a connecting slot on the side away from the outer panel 31, and the inner panel 32 is provided with a protruding plug-in portion 321. The protruding plug-in portion 321 of the inner panel 32 is snapped into the connecting slot of the plastic heat-insulating insert 33, so that the inner panel 32 is connected to the plastic heat-insulating insert 33, and at the same time, the inner panel 32 and the outer panel 31 do not contact each other.

[0093] The side wall of the outer panel 31 is provided with foaming holes, and the polyurethane foaming agent is filled into the sandwich cavity surrounded by the outer panel 31, the inner panel 32 and the plastic insulation insert 33 to form a polyurethane foam layer 34 in the sandwich cavity.

[0094] In this embodiment, the insulation panel adopts a double-layer sandwich structure, with the outer and inner panels made of steel plates, each connected to a plastic insulation insert without contacting the other. This blocks the heat transfer path at the side walls of the insulation panel, reduces heat exchange between the inside and outside, and eliminates the occurrence of cold bridges.

[0095] Furthermore, in the anti-cold bridge box for the air-conditioning unit in this embodiment, the thermal insulation panel 3 further includes: a sheet metal insert 35 .

[0096] The plastic heat-insulating insert 33 is provided with receiving grooves on both the inner and outer sides. The two sheet metal inserts 35 are respectively inserted into the two receiving grooves of the plastic heat-insulating insert 33 .

[0097] In this embodiment, the sheet metal inserts not only increase the strength of the insulation panel itself, but also when the insulation panel is assembled, 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 box for the air-conditioning unit in this embodiment further includes: an inspection door 5 and a center support 6.

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

[0100] Inspection doors 5 are provided on the left and right sides of the square frame, one side of the inspection door 5 is hinged to the center support 6, and the other side of the inspection door 5 is provided with a door lock structure for locking the inspection door 5. Through the inspection door 5, it is convenient to inspect and maintain the air conditioning unit in the box.

[0101] Further, such as Figure 8 , Figure 9 and Figure 10 As shown, in the cold bridge prevention box for the air-conditioning unit in this embodiment, the middle support 6 includes: a second aluminum alloy outer frame 61 , a second aluminum alloy inner frame 62 and a second plastic 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 in the shape of a rectangular frame and is also provided with insertion slots.

[0104] Both ends of the second plastic heat insulation strip 63 are provided with insertion bumps, and its material is PVC.

[0105] Both ends of the second aluminum alloy outer frame 61 are respectively connected to the second aluminum alloy inner frame 62 through the second plastic heat insulation strip 63, so that the middle support 6 is also formed into a broken bridge aluminum alloy profile frame structure, blocking the heat transfer path at the middle support, reducing heat loss, and preventing the occurrence of cold bridges.

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

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

[0108] A heat preservation cotton 4 is provided between the heat preservation panel 3 and the second aluminum alloy inner frame 62.

[0109] Furthermore, the cold bridge prevention box body for the air conditioner unit in this embodiment further includes: a channel steel bottom frame 7.

[0110] The channel steel bottom frame 7 is in the shape of a rectangular frame, and the aluminum alloy profile frame 1 and the rectangular frame formed by splicing and assembling a plurality of tees 2 are arranged on the channel steel bottom frame 7, so that the cold bridge prevention box body is set off the ground, reducing the heat exchange between the box body and the ground, and also preventing the ground water vapor from damaging the box body, such as causing the box body to corrode and mildew, etc., and extending the service life of the box body.
