[0025] like Figure 2 As shown, it is a chassis of an embodiment of the utility model.
[0026] See also Figure 2 As shown, the chassis 100 of the embodiment of the utility model includes a disk body 10 and a bracket 20. The disk body 10 is provided with a heat exchanger installation area 11 and a drainage hole 12. The drainage hole 12 is located beside the bracket 20. A plurality of brackets 20 are provided. The plurality of brackets 20 are arranged at intervals in the heat exchanger installation area 11. The bracket 20 includes a support plate 21 and side plates 22 arranged on both sides of the support plate 21. A through groove 211 is opened on the support plate 21. The support plate 21 is installed on the disk body 10 through the side plates 22, and a gap is formed between the support plate 21 and the disk body 10.
[0027] In this embodiment, the support plate 21 and the side plate 22 are an integrated structure, which can provide better overall stability and strength, making the connection between the support plate 21 and the side plate 22 more secure and reducing the possibility of loosening or deformation.
[0028] In this embodiment, the area of the through groove 211 is at least half of the area of the support plate 21 . By providing a through groove 211 with a larger area on the support plate 21 , the water leakage speed can be accelerated.
[0029] In this embodiment, the plate body 10 is a CNC-bent part.
[0030] In this embodiment, the bracket 20 is a metal part, specifically, the bracket 20 is a stainless steel bracket 20. The stainless steel bracket 20 has high strength and hardness, and can effectively support the heat exchanger 200 to ensure the stability and safety of the heat exchanger 200 during normal operation.
[0031] The chassis 100 of the utility model embodiment is provided with a support 20 on the dish body 10, and the support 20 is used to lift the heat exchanger 200, so that the bottom of the heat exchanger 200 is not in direct contact with the dish body 10, which can prevent the heat exchanger 200 from forming ice when the ambient temperature is low or the defrosting is not good. In addition, a through groove 211 is provided on the support plate 21 of the support 20, and a gap is formed between the support plate 21 and the dish body 10, so that water can be leaked in time to discharge the accumulated water.
[0032] See also Figure 2 As shown, in certain embodiments, exemplarily, a notch 221 is provided in the middle of the side panel 22, that is, the edge of the plate is hollowed out, which can further accelerate the water leakage speed and reduce the contact area between the bottom of the heat exchanger 200 and the support 20 to prevent ice from forming when the ambient temperature is low or the defrosting is poor.
[0033] In this embodiment, the area of the notch 221 accounts for at least one third of the area of the side plate 22 , which can speed up the water leakage.
[0034] See also Figure 2 As shown, in some embodiments, illustratively, a plurality of drainage holes 12 are provided, and the plurality of drainage holes 12 are spaced apart on the inner sides of the plurality of support members 20 , which can increase the drainage speed.
[0035] Furthermore, the drainage hole 12 is arranged in a cone shape, so that the bottom of the drainage hole 12 is narrower, and water can be discharged more quickly, thereby reducing the time of water accumulation in the tray body 10 and improving drainage efficiency.
[0036] In this embodiment, a drainage pipe (not shown) may also be installed at the bottom of the drainage hole 12 to facilitate drainage.
[0037] See also Figure 2 As shown, in certain embodiments, exemplarily, an electric heating belt 30 is provided on the disk body 10, and the electric heating belt 30 is installed in the gap formed by the support plate 21 and the disk body 10. By providing the electric heating belt 30, the phenomenon of frost condensation on the disk body 10 can be further prevented. At the same time, the support 20 can protect and fix the electric heating belt 30, so that the electric heating belt 30 can better serve the defrosting and smooth drainage of the heat exchanger 200 above.
[0038] In this embodiment, when t≤0°C and the fan state of the air conditioning unit is on, the electric heating belt 30 is turned on; when t≥2°C or the fan state of the air conditioning unit is off, the electric heating belt 30 is turned off.
[0039] In this embodiment, the shape of the electric heating belt 30 corresponds to the shape of the heat exchanger 200. For example, when the radiator is an L-shaped radiator or a U-shaped heat exchanger 200, the electric heating belt 30 is also an L-shaped electric heating belt 30 or a U-shaped electric heating belt 30.
[0040] Furthermore, a mounting groove (not shown) is provided in the heat exchanger mounting area 11, and the mounting groove is provided below the support plate 21, and the electric heating belt 30 is installed in the mounting groove. Such a design can position and install the electric heating belt 30, and further fix the electric heating belt 30.

[0042] In this embodiment, the radiator is an L-shaped radiator or a U-shaped heat exchanger 200. The L-shaped heat exchanger 200 or the U-shaped heat exchanger 200 has a compact structure and occupies little space. The L-shaped or U-shaped heat exchanger 200 has a large heat exchange area, which can effectively improve the heat exchange efficiency, quickly transfer heat, and achieve good heat dissipation effect.
[0043] The air-conditioning unit of the utility model embodiment is provided with a support 20 on the disk body 10, and the support 20 is used to lift the heat exchanger 200, so that the bottom of the heat exchanger 200 is not in direct contact with the disk body 10, which can prevent the heat exchanger 200 from forming ice when the ambient temperature is low or the defrosting is not good. In addition, a through groove 211 is formed on the support plate 21 of the support 20, and a gap is formed between the support plate 21 and the disk body 10, so that water can be leaked in time to discharge the accumulated water.
