Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0028] When the outdoor unit of a conventional upper air conditioner is in operation, air enters from the side of the heat exchanger and blows out from the top of the outdoor unit. The air flow in the upper part of the heat exchanger is shorter, and the air flow in the lower part of the heat exchanger is longer, and after the air in the lower part of the heat exchanger enters the outdoor unit, it will be blocked by the internal components, so the air flow in the upper part of the heat exchanger The flow velocity is higher, and the air velocity at the lower part is lower. By measuring the wind v...

The invention provides an air grid and an air conditioner. The air grid comprises a grid body and air deflectors installed on the grid body, and the air guiding distance of the air deflectors located on the upper portion of the grid body is larger than that of the air deflectors located on the lower portion of the grid body. According to the technical scheme, the air guide distance of the air deflectors located on the upper portion of the grid body is larger than that of the air deflectors located on the lower portion of the grid body, so that the resistance of the lower portion of the air grid is larger than that of the upper portion of the air grid, the air speed of the lower portion of the air grid is increased, the air flow speed of the lower portion of the heat exchanger is increased, the wind speed distribution uniformity of the heat exchanger is improved, the heat exchange performance of the heat exchanger is improved, and the problem that the overall performance of the heat exchanger is poor is solved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air grill and an air conditioner. Background technique [0002] The outdoor unit of the air conditioner with the upper air outlet structure usually has uneven distribution of the air volume of the heat exchanger due to its own structural limitations. The head-on wind velocity at the upper part of the heat exchanger is 2-4 times that of the lower part. In the case of evaporation, the superheat of the top flow path is very large, and the superheat of the bottom flow path is very small. [0003] In the prior art, it is usually possible to balance the difference in superheat between the upper part and the bottom by adjusting the design of the flow path and the length of the capillary tube, but to a certain extent, the pressure loss of the flow path at the bottom is increased, and the overall performance of the heat exchanger has not been brought into full play. maximum. ...
