Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a power supply box and an outdoor unit for an air conditioner. Background Technology

[0002] Power supply units for electrical equipment such as air conditioners typically require a power supply box and a cover, which are usually connected and secured with screws. With increasing user demands, the use of high-capacity inverter air conditioners has increased significantly. The inverter modules used in these units generate substantial heat due to their high switching speed and power consumption. This heat causes both the ambient temperature and the component's own temperature to rise, ultimately reducing its lifespan. To reduce heat generation in the power supply unit, heat sinks are typically installed on the outer surfaces of the inverter module components. The heat from the components is conducted to the heat sinks, and the outdoor unit's fan blows air to remove the heat from the heat sinks. However, the heat absorbed by the heat sinks is limited. The heat released by the components accumulates inside the power supply box and cannot dissipate. This results in a high ambient temperature inside the power supply box, causing the components to operate in a high-temperature environment for extended periods, leading to a decrease in both efficiency and lifespan. Utility Model Content

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a power supply box and outdoor unit for an air conditioner, which can effectively improve the heat dissipation performance of the power supply box, thereby reducing the internal temperature of the power supply box and preventing electronic components from being damaged by being in a high-temperature environment for a long time.

[0004] To achieve the above objectives, a first aspect of this utility model provides a power supply box for an air conditioner, comprising a power supply box body and a plurality of heat dissipation fins. The power supply box body is a hollow, closed structure. A refrigeration unit is disposed at the lower interior of the power supply box body. A mounting portion for mounting components is disposed on one side of the interior of the power supply box body. The plurality of heat dissipation fins are disposed on the outer side of the mounting portion. A heat dissipation area is disposed on the side of the power supply box body adjacent to the mounting portion. The heat dissipation area is square in shape and is composed of a plurality of rows of spaced ventilation holes, which communicate with the interior of the power supply box body.

[0005] In one embodiment, the length of the heat dissipation area is greater than or equal to 125 mm, and the width of the heat dissipation area is greater than or equal to 12 mm.

[0006] In one embodiment, the length of the heat dissipation area is 126mm and the width of the heat dissipation area is 12mm.

[0007] In one embodiment, the ventilation hole is a circular hole structure with a diameter of 3mm.

[0008] In one embodiment, the total area of ​​the plurality of ventilation holes is S, where S ≥ 465 mm. 2 .

[0009] In one embodiment, the total area S of the plurality of ventilation holes is 466 mm². 2 .

[0010] In one embodiment, several of the heat dissipation fins are arranged laterally and at equal intervals on the outer side of the mounting portion.

[0011] Therefore, the power supply box for an air conditioner according to this embodiment of the present invention has a heat dissipation area on one side of the power supply box near the mounting part, and a ventilation hole is formed through the heat dissipation area to connect to the inside of the power supply box. In this way, when the power supply box is installed inside the outdoor unit of the air conditioner, it can effectively dissipate heat through the heat dissipation fins, cool the internal components through the refrigeration unit inside the power supply box, and form an effective airflow loop through the ventilation hole in the heat dissipation area. This utilizes the heat dissipation airflow inside the outdoor unit to simultaneously remove heat from the heat dissipation fins and the ventilation hole, thereby improving the heat dissipation effect of the power supply box, reducing the overall temperature inside the power supply box, and preventing damage to electronic components from prolonged exposure to high temperatures. Furthermore, by limiting the total ventilation area and diameter of the ventilation holes, insects and other animals can be prevented from entering the inside of the power supply box, avoiding short circuits or damage to the components inside the power supply box.

[0012] A second aspect of this utility model provides an outdoor unit for an air conditioner, comprising a power supply box for an air conditioner as described in any of the preceding embodiments, and a heat dissipation duct, wherein the power supply box is disposed within the heat dissipation duct. The outdoor unit for an air conditioner according to this utility model can effectively improve the heat dissipation performance of the power supply box, thereby reducing the internal temperature of the power supply box and preventing electronic components from being damaged by prolonged exposure to high temperatures.

[0022] In related technologies, power supply units for electrical equipment such as air conditioners generally require a power supply box and a cover, which are typically connected and secured using screws. With increasing user demands, the use of high-capacity inverter air conditioners has significantly increased. The inverter modules used in these units generate substantial heat due to their high switching speed and power consumption. This heat causes both the ambient temperature and the component's own temperature to rise, ultimately reducing its lifespan.

The heat dissipation area 11 is square in shape and is composed of a plurality of rows of spaced ventilation holes 12.

[0025] In this embodiment of the invention, the length of the heat dissipation area 11 is greater than or equal to 125 mm, and the width of the heat dissipation area 11 is greater than or equal to 12 mm. For example, the length of the heat dissipation area 11 may be, but is not limited to, 126 mm, and the width of the heat dissipation area 11 may be, but is not limited to, 12 mm.

Furthermore, the ventilation hole 12 of the heat dissipation area 11 forms an effective air circulation loop, using the heat dissipation air duct inside the outdoor unit of the air conditioner to simultaneously remove heat from the heat dissipation fins 13 and the ventilation hole 12, thereby improving the heat dissipation effect of the power supply box body 10, reducing the overall temperature inside the power supply box body 10, and preventing electronic components from being damaged by prolonged exposure to high temperatures. In addition, by limiting the total ventilation area and the diameter of the ventilation hole 12, insects and other animals can be prevented from entering the interior of the power supply box body 10, avoiding short circuits or damage to the components inside the power supply box body 10.

[0027] A second aspect of this utility model provides an outdoor unit for an air conditioner, comprising a power supply box for an air conditioner as described in any of the preceding embodiments, and a heat dissipation duct, wherein the power supply box 10 is disposed in the heat dissipation duct.
