The specific structure of the heat exchanger connecting assembly will be mainly described below.
Referring to fig. 1 to 2, in an embodiment of the present invention, the heat exchanger connecting assembly is used for an air conditioner including a first heat exchanger 140 and a second heat exchanger 150, and includes:
a first connector 910, wherein the first connector 910 includes a first connection portion 911 and a second connection portion 912 fixedly connected to the first connection portion 911;

Specifically, in this embodiment, the air conditioner is exemplified by a ceiling fan. This smallpox machine includes:
the air conditioner comprises a machine body 100, wherein the machine body 100 is provided with an air inlet, an air outlet and an air duct communicated with the air inlet and the air outlet;
the panel 800 is provided with a first through opening 810 corresponding to the air inlet, a second through opening 820 corresponding to the air outlet, and the panel 800 between the first through opening 810 and the second through opening 820 is fixedly connected with the machine body 100.
Specifically, in the present embodiment, the main body 100 is a cuboid (a cuboid with a concave or convex shape according to actual needs), and the air inlet and the air outlet are disposed on the same side of the main body 100. In some embodiments, the number of the air outlets is multiple, and the multiple air outlets are arranged around the air inlet to form a layout of the middle air inlet and the peripheral air outlets.
The fuselage 100 comprises a surrounding plate 110 heat-insulating layer 130, the surrounding plate 110 and the chassis 200 form an installation cavity, a heat exchanger 120 of the air conditioner is arranged in the installation cavity, and the heat-insulating layer 130 is arranged between the heat exchanger 120 and the surrounding plate 110. The number of the enclosing plates 110 can be two or four, and when the number of the enclosing plates 110 is four, the four enclosing plates 110 are arranged on four side walls of the seat installation cavity, and the bottom of the seat installation cavity of the chassis 200. The heat exchanger 120 is disposed in the mounting cavity, and the heat exchanger 120 may be detachably connected to the enclosure 110 and may also be detachably connected to the chassis 200. The insulating layer 130 may be made of various materials, such as cotton fabric, and the foam layer is taken as an example in this embodiment. The heat insulation layer 130 is disposed between the surrounding plate 110 and the heat exchanger 120 to insulate the heat exchanged gas and prevent the heat exchanged gas from directly exchanging heat with the gas outside the body 100. The insulating layer 130 is fixedly connected to the surrounding plate 110 and/or the base plate 200.
The shroud 110 and the chassis 200 are required to provide support for the components of the ceiling engine, so that the shroud 110 and the chassis 200 are made of hard materials, such as steel plates. In order to increase the load-bearing strength of the chassis 200, a plurality of reinforcing ribs 930 are arranged on the chassis 200. The panel 800 is disposed on the machine body 100 on a side opposite to the chassis 200, and the panel 800 is provided with openings corresponding to the air inlet and the air outlet, respectively, for air to flow into or out of the air duct. Of course, in some embodiments, the ceiling fan further includes a flow guide ring 400, and the flow guide ring 400 is disposed corresponding to the air inlet, so that the air flow can enter the air duct more stably and accurately. A water pan 500 is further arranged below the heat exchanger 120, so that condensed water on the heat exchanger 120 can flow out in time, and the heat exchange efficiency of the heat exchanger 120 is ensured. Of course, in some embodiments, in order to control the ceiling fan more stably, an electronic control box 300 is needed to be disposed on the circuit control board for protecting the ceiling fan, so as to ensure that the control circuit board is not affected by the outside world and works stably.

Since the first through opening 810 and the second through opening 820 are opened at the same side of the panel 800, the position where the panel 800 is connected to the body 100 is not at the edge of the panel 800 but at a position where the panel 800 is eccentric. The panel 800 is fixedly connected to the body 100 between the first opening 810 and the second opening 820, and the panel 800 is attached to the heat exchanger 120 and the insulating layer 130. The fixing connection mode has a plurality of modes, and the fixing connection mode can be realized through screws or can be realized through gluing. It should be noted that the range of the panel 800 between the first through opening 810 and the second through opening 820 is very flexible, and can be defined according to actual needs, and the maximum range can be defined until all the panels 800 except the first through opening 810 and the second through opening 820 are attached and fixed to the body 100, and only the panel 800 needs to be partially connected to the body 100 at a deviated position. The first through opening 810 is rectangular, the second through opening 820 is elongated, and the second through opening 820 extends along the length of the first through opening 810 in a square shape or along the width direction of the first through opening 810. Of course, in other embodiments, the relative position relationship between the first through hole 810 and the second through hole 820 can be adjusted according to actual requirements.
The part between the first through opening 810 and the second through opening 820 of the panel 800 is fixedly connected with the machine body 100, so that the connection position of the panel 800 and the machine body 100 is close to the middle part of the panel 800 (far away from the edge of the panel 800), when the panel 800 acts by the self weight, the connection position of the panel 800 and the machine body 100 can better overcome the gravity of the panel 800, when the panel 800 is stressed or affected by temperature difference, the panel 800 has higher deformation resistance strength, the panel 800 is more difficult to deform, the stability of the panel 800 after being installed is favorably improved, the air flow in an air duct is prevented from leaking out from the space between the panel 800 and the machine body 100, the condensation phenomenon caused by cold leakage is avoided, the potential safety hazard of accidents caused by condensation is eliminated, and meanwhile, the phenomenon that the temperature sensor of the air conditioning system is interfered due to air leakage is also avoided.

In order to improve the connection stability between the refrigerant pipes of the first heat exchanger 140 and the second heat exchanger 150 and the first connection member 910, the first connection portion 911 includes a first connection plate, and the second connection portion 912 includes a second connection plate, and the first connection plate and the second connection plate are fixedly connected in an L shape. The first limiting holes 913 are arranged along the length direction of the first connecting plate, and the second limiting holes 914 are arranged along the length direction of the second connecting plate. The first connecting plate is attached to and detachably connected with an end plate of the first heat exchanger 140; and/or the second connecting plate is attached to and detachably connected with an end plate of the second heat exchanger 150.
In this embodiment, the first connecting plate and the second connecting plate may have various shapes, such as a square shape, a circular shape, a polygonal shape, or even an irregular shape. The first connecting plate and the second connecting plate are integrally formed, the first connecting plate and the second connecting plate are arranged at an included angle, the included angle is larger than zero degree and smaller than 180 degrees, and the included angle is 90 degrees as an example. The first limiting hole 913 and the second limiting hole 914 are both slotted holes, the length direction of the first limiting hole 913 is arranged along the length direction of the first connecting plate, and the length direction of the second limiting hole 914 is arranged along the length direction of the second connecting plate.
