Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an outdoor unit of an air conditioner. Background Art

[0002] Air conditioners are typically divided into indoor and outdoor units, with the outdoor unit primarily installed outdoors. The outdoor unit of a split, floor-standing air conditioner typically consists of a grille, front panel, heat exchanger, left side panel, chassis, bracket, fan blades, and windshield panels. When the outdoor unit is operating, the fan blades rotate, driving airflow through the heat exchanger, removing heat before being blown out through the vents.

[0003] The heat exchanger of a typical air conditioner outdoor unit covers a large area at the rear and left ends of the air conditioner. A guide ring is provided on the front panel to guide the air driven by the fan blades. During operation of the air conditioner outdoor unit, the air flowing through the air duct only passes through the heat exchanger once before being blown out, resulting in low heat exchange efficiency. However, there are currently some related technical solutions for air conditioner outdoor units in the prior art. For example, the invention patent with publication number: CN111256216A discloses an air conditioner outdoor unit and an air conditioner having the same, comprising: a chassis, a first heat exchanger, and a second heat exchanger, wherein the first heat exchanger is mounted on the chassis; the second heat exchanger is mounted on the chassis; a distance is provided between the first heat exchanger and the second heat exchanger; the first heat exchanger and the second heat exchanger are arranged sequentially in the direction of the air flow; or the air conditioner outdoor unit further comprises a first fan assembly, wherein the first fan assembly is arranged between the first heat exchanger and the second heat exchanger, and the fan blades of the first fan assembly are oriented toward the top of the air conditioner outdoor unit. In this technical solution, the first fan assembly is arranged between the first heat exchanger and the second heat exchanger, which can effectively eliminate the contact thermal resistance of the two heat exchangers, reduce wind resistance, and effectively improve the heat exchange efficiency of the heat exchanger.

[0004] However, in actual use, there is a problem: since there is an air supply gap between the two heat exchangers, the installation of two heat exchangers still results in low heat exchange efficiency. Utility Model Content

[0019] Compared with the existing technology, the technical effects achieved by adopting this technical solution are: the wind ring is located near the second long side; the guide ring is arranged around the fan blades and extends along the first direction to better guide the airflow discharged by the fan blades, while also improving the stability of the fan blade rotation and the installation strength, thereby improving the operating stability of the outdoor unit. In this application, the front panel is eliminated, and the wind ring is directly mounted on the chassis while providing a side panel structure. By replacing the front panel with the side panel structure and the wind ring, the air outlet area can be increased and the structural cost can be reduced.

[0043] In a specific embodiment, D1 is a first direction, D2 is a second direction, and D3 is a third direction; D1 is the width of the heat exchanger 300 and the air conditioner outdoor unit; D2 is the length of the heat exchanger 300 and the air conditioner outdoor unit; D3 is the extension direction of the side panel structure 120 and the height of the heat exchanger 300 and the air conditioner outdoor unit; and the first, second, and third directions are mutually perpendicular. The heat exchanger 300 includes a first long side 310 and a second long side 320 connected to each other, and the first long side 310 and the second long side 320 are respectively arranged on the air inlet and air outlet sides of the fan assembly. This allows air outside the heat exchanger 300 to flow through the first long side 310 on the air inlet side and then out through the second long side 320 on the air outlet side, resulting in a second flow through the heat exchanger 300, thereby increasing the air outlet area and improving heat exchange efficiency. At the same time, the fan assembly 400 is shielded by the heat exchanger 300, which reduces the exposed area of ​​the fan assembly 400, reduces the impact of external insects and harsh environments on the life of the fan assembly 400, and prevents users from touching the fan assembly 400, thereby improving safety performance; under the condition of meeting the strength of the air conditioner outdoor unit, the air conditioner front panel and grille can no longer be used, saving the cost of the air conditioner.

[0044] In other words, the heat exchanger 300 is provided with an accommodating groove 304 , which is used to accommodate the fan assembly 400 , and the accommodating groove 304 divides the heat exchanger 300 into a first long side 310 and a second long side 320 .
