Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air conditioning device. Background Technology

[0002] With the improvement of living standards, air conditioning has become an indispensable appliance in homes. Air conditioning units are equipped with heat exchangers, whose main function is to release absorbed heat to the outdoor environment. To improve heat dissipation efficiency, outdoor units are usually equipped with fans to accelerate heat dissipation and promote faster heat diffusion into the surrounding environment. However, in current air conditioning designs, the heat exchanger typically exchanges air with the outdoor environment through grilles on the unit's walls. This grille design has many obstructions, resulting in insufficient ventilation between the heat exchanger and the outdoor environment, thus limiting the improvement of heat exchange efficiency. Furthermore, because the heat exchange area is limited by the overall size of the air conditioning unit, it may be insufficient to meet high-load heat exchange demands, thereby affecting the cooling and heating performance of the air conditioning unit. Utility Model Content

[0048] Please see Figure 1-4In one embodiment of this utility model, an air conditioning device includes a housing 10, a heat exchanger 20, and a fan assembly 30. The heat exchanger 20 is disposed inside the housing 10, and the fan assembly 30 is disposed inside the housing 10 and is used to guide the airflow outside the housing 10 to exchange heat with the heat exchanger 20. The housing 10 includes a top plate 11, a bottom plate 12 disposed below the top plate 11, and an air outlet plate 13 connecting the top plate 11 and the bottom plate 12. The air outlet plate 13 is provided with an air outlet 130, which is used to exchange airflow with the heat exchanger 20. After heat exchange, the airflow is discharged. In this embodiment, the heat exchanger 20 includes a coil 21, which is arranged on three inner sides of the housing 10 except for the air outlet plate 13. That is, the coil 21 is arranged on the left side, rear side and right side of the housing 10. The coil 21 arranged on the rear side is directly opposite to the air outlet plate 13. In other embodiments, the heat exchanger 20 can be designed to include coils 21 arranged on at least two inner sides of the housing 10, and at least a portion of the coils 21 are directly opposite to the air outlet plate 13, depending on the specific requirements.

[0049] In the above embodiment, the heat exchanger 20 of the air conditioning equipment is not connected to the outside through a grille. Without the barrier of a grille, it can be directly connected to the outside. The heat exchanger 20 includes a coil 21, which is arranged on the three inner sides of the housing 10 except for the air outlet plate 13. That is, the coil 21 is arranged on the left side, rear side and right side of the housing 10. The heat exchange area is large. With the help of the above structural design, the outdoor unit can increase the supply and return air area, reduce the air flow resistance in the outdoor unit, reduce the fan power consumption of the outdoor unit, and improve the heat dissipation efficiency of the outdoor unit, thereby achieving fan energy saving and increasing the air conditioning cooling capacity.

[0050] For more details, please refer to Figure 1-4 The coil 21 includes a first section 22, a second section 23, and a third section 24 respectively disposed on the inner side of the housing 10 excluding the air outlet plate 13. The top plate 11, the bottom plate 12, the air outlet plate 13, the first section 22, the second section 23, and the third section 24 enclose the housing 10, with the second section 23 facing the air outlet plate 13. The coil 21 is designed with three sections, which directly serve as the three uncovered sides of the housing 10, resulting in a large heat exchange area. Except for the air outlet plate 13, which is the air outlet surface, the other three sides are air inlet surfaces, increasing the air supply and return area of ​​the outdoor unit, reducing the air flow resistance inside the outdoor unit, reducing the fan power consumption of the outdoor unit, and improving heat dissipation efficiency, thus helping to achieve fan energy saving and increase the air conditioning cooling capacity.

[0051] In one embodiment, the air conditioning device is an outdoor unit or an indoor unit. When the coil 21 is applied to the condenser, the air conditioning device is an outdoor unit; when the coil 21 is applied to the evaporator, the air conditioning device is an indoor unit.

[0052] For further details, please refer to Figure 1-4 The coil 21 includes multiple sub-coils 210 arranged along the height direction of the casing 10. Each sub-coil 210 is U-shaped and has heat exchange fins on its outer wall. The sub-coils 210 of the outdoor unit heat exchanger 20 are U-shaped and arranged along the height direction of the casing 10, thus forming a three-section coil 21 structure. The three-section coil 21 directly serves as the three uncovered sides of the casing 10, resulting in a large heat exchange area.

[0053] Please see Figure 1-4 In one embodiment of this utility model, the housing 10 further includes a first reinforcing fixing plate 14 and a second reinforcing fixing plate 15. The first reinforcing fixing plate 14 is connected to the front side of the middle section of the multiple sub-coils 210 in the heat exchanger 20, and the second reinforcing fixing plate 15 is connected to the rear side of the middle section of the multiple sub-coils 210 in the heat exchanger 20. One end of the first reinforcing fixing plate 14 and the second reinforcing fixing plate 15 are both connected to the top plate 11, and the other end is both connected to the bottom plate 12. The middle section of the U-shaped sub-coil 210 is suspended, and the sub-coil 210 may shift or loosen in the middle part. During transportation, excessive vibration may even cause significant displacement, leading to scrap. The first reinforcing fixing plate 14 and the second reinforcing fixing plate 15 are used to reinforce and fix the middle section of the sub-coil 210.

[0054] Please see Figure 1-4 In one embodiment of this utility model, both the first reinforcing fixing plate 14 and the second reinforcing fixing plate 15 are provided with multiple ventilation holes 140. The first reinforcing fixing plate 14 and the second reinforcing fixing plate 15 may partially obstruct the air intake into the outdoor unit, affecting heat exchange. Therefore, both the first reinforcing fixing plate 14 and the second reinforcing fixing plate 15 are provided with multiple ventilation holes 140 to facilitate air intake and heat exchange.

[0055] Please see Figure 1-4In one embodiment of this utility model, the housing 10 further includes a first support column 16 and a second support column 17 connected between the top plate 11 and the bottom plate 12, and located away from the air outlet plate 13. The first support column 16 and the second support column 17 are respectively located at the corners of the housing 10, with one end connected to the top plate 11 and the other end connected to the bottom plate 12. The ends of the top plate 11 and the bottom plate 12 away from the air outlet plate 13 are suspended. To strengthen the fixation, the first support column 16 and the second support column 17 are provided. One end of the first support column 16 and the second support column 17 are connected to the top plate 11, and the other end of the first support column 16 and the second support column 17 are connected to the bottom plate 12, thereby improving the structural strength of the housing 10.

[0056] Please see Figure 1-4 In one embodiment of this utility model, the air outlet plate 13 is provided with two air outlets 130, and the fan assembly 30 includes axial flow fans 31 that are arranged one-to-one with the air outlets 130. The axial flow fans 31 are used to forcibly absorb the outside natural wind from the housing 10 and exchange heat with the heat exchanger 20.

[0057] Please see Figure 1-4 In one embodiment of this utility model, the air conditioning equipment further includes a refrigerant pump 40 and an electrical control box 50. Both the refrigerant pump 40 and the electrical control box 50 are disposed inside the housing 10. The refrigerant pump 40 is used for forced convection circulation of the refrigerant, and the electrical control box 50 is used to control the operating status of the outdoor unit, specifically controlling the start-up, stop, cooling, and heating states of the outdoor unit. Because the refrigerant pump 40 is disposed inside the housing 10, when the outdoor temperature drops to a set value, the compressor is stopped, and a low-power refrigerant pump 40 is used for forced convection circulation of the refrigerant, reducing energy consumption. Arranging the refrigerant pump 40 and the electrical control box 50 inside the housing 10 improves the structural compactness and layout symmetry of the outdoor unit. This, in turn, improves the uniformity of temperature distribution in the outdoor unit (compact arrangement reduces gaps between components, thereby reducing heat accumulation in localized areas. When components are closely arranged, the heat they generate can be more evenly distributed throughout the entire outdoor unit, reducing the risk of localized overheating, resulting in uniform temperature distribution in all areas of the outdoor unit), while simultaneously reducing the structural volume of the outdoor unit.

[0058] For more details, please refer to Figure 1-4 The two axial flow fans 31 are located on one diagonal line inside the housing 10, and the electrical control box 50 and the refrigerant pump 40 are located on the other diagonal line inside the housing 10. This structural arrangement improves the compactness and symmetry of the outdoor unit, thereby reducing its size while improving the uniformity of temperature distribution.

[0059] Please see Figure 1-4 In one embodiment of this utility model, a liquid storage tank 60 is also included. The liquid storage tank 60 is used to store liquid refrigerant. The liquid storage tank 60 is connected to the inlet end of the refrigerant pump 40. The liquid storage tank 60 is used to provide refrigerant to the heat exchanger 20 and protect the refrigerant pump, ensuring that the refrigerant in the air conditioning system is always saturated.

[0060] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
