Problems solved by technology
As the wind blows directly on the heat exchanger of the blower type unit, there is a local wind speed on the heat exchanger, and if the heat exchanger is installed at a certain angle to the unit, the wind direction when the wind passes through the heat exchanger will be related to the heat exchange rate. The direction of the fins on the heat exchanger is not horizontal, it is easy to scratch the fins, causing abnormal sound of the wind blowing the fins, especially for commercial patio machines, the wind direction and the direction of the fins have a certain angle, and due to space constraints, the heat exchanger The distance between the fan impeller and the fan impeller is relatively short. When the local wind speed on the heat exchanger is high, it is more likely to produce abnormal sound quality.
[0003] In the prior art, indoor units that reduce air-conditioning noise have appeared, such as the utility model patent whose notification number is CN205079340U. In the disclosed indoor unit structure, a spoiler is arranged on the inner wall of the heat exchanger, and the spoiler is located on the circle of the vortex fan. The windward side of the heat exchanger paper in the area with the smallest distance between the shapes. This structure can only adjust the wind speed in the area where the spoiler is located, and cannot achieve the effect of reducing noise comprehensively. There is still the possibility of large noise during use. possible

Embodiment Construction
[0031] Such as Figures 1 to 3 As shown, the air conditioner flow equalization structure proposed by the present invention includes: fan impeller 1 and heat exchanger 2, heat exchanger 2 is arranged on the periphery of fan impeller 1, and a circle of uniformity is arranged between fan impeller 1 and heat exchanger 2 The flow plate 3 surrounds the fan impeller 1, and the flow distribution holes 31 are distributed on the flow distribution plate 3. The wind blown by the fan impeller 1 hits the flow distribution plate 3, and the air flow is rectified by the flow distribution holes 31 before In contact with the surface of the heat exchanger 2, the wind speed and direction of the wind blowing on the surface of the heat exchanger 2 are changed by the equalizer 3, so as to prevent the airflow from scraping the fins on the heat exchanger 2 and eliminate the sound of the wind blowing the fins.
[0032] In a preferred embodiment, as image 3 As shown, the minimum distance between the eq...

The invention discloses an air conditioner flow homogenizing structure and an air conditioner. The air conditioner flow homogenizing structure comprises a draught fan impeller, a heat exchanger arranged on the periphery of the draught fan impeller and a circle of flow homogenizing plate surrounding the draught fan impeller. The flow homogenizing plate is located between the draught fan impeller and the heat exchanger. Flow homogenizing through holes are evenly distributed in the flow homogenizing plate. According to the air conditioner flow homogenizing structure and the air conditioner, the noise of the air conditioner can be effectively lowered, and air blowing fin noise is eliminated.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner flow equalization structure and the air conditioner. Background technique [0002] The existing air conditioner indoor unit structure is divided into blowing type and suction type according to the air outlet mode of the fan. The wind blown from the fan outlet first passes through the heat exchanger and then goes out from the unit outlet. The air does not go through the heat exchanger, and the way it goes out directly from the air outlet of the unit is the suction type. As the wind blows directly on the heat exchanger of the blower type unit, there is a local wind speed on the heat exchanger, and if the heat exchanger is installed at a certain angle to the unit, the wind direction when the wind passes through the heat exchanger will be related to the heat exchange rate. The direction of the fins on the heat exchanger is not horizontal, it is easy to sc...
