Embodiment 1

[0037] Such as figure 1 - image 3 Shown is a specific embodiment of a heat exchange fan assembly, including a centrifugal fan and a heat exchanger 2 . The centrifugal fan includes centrifugal blades 1, the diameter of which is L2; ​​the heat exchanger 2 is arranged on the air inlet side of the centrifugal fan, and the width of the heat exchanger 2 is L1. In order to make the heat exchanger 2 completely in the flow field driven by the centrifugal fan 1, so that the heat exchanger 2 can fully exchange heat with the air, it is necessary to satisfy L2≥L1; the width of the heat exchanger 2 is the same as that of the centrifugal fan The ratio of the diameters of 1 is A, and in order to ensure the heat exchange area of ​​the heat exchanger 2, in this embodiment, 0.8≤A≤1. In this embodiment, in order to increase the contact area between the heat exchanger 2 and the air, the heat exchanger 2 adopts a bent heat exchanger, and the surface of the heat exchanger 2 close to the centrifug...

Embodiment 2

[0041] This embodiment provides an air conditioner, which includes the heat exchange fan assembly provided in the above embodiments. Since the heat exchange performance of the heat exchanger 2 is better, the performance of the air conditioner is better.

Abstract

The invention provides a heat exchange fan assembly and a heat exchanger. The heat exchange fan assembly comprises a centrifugal fan and the heat exchanger; the centrifugal fan comprises centrifugal fan blades, and the diameter of the centrifugal fan blades is L2; the heat exchanger is arranged on the air inlet side of the centrifugal fan, the width of the heat exchanger is L1, and the width of the heat exchanger refers to the distance of two end points, close to the centrifugal fan blade, of the heat exchanger in the horizontal direction; and L2 is greater than or equal to L1. The heat exchanger is completely located in the flow field driven by the centrifugal fan blades, so that the heat exchanger fully exchanges heat with air, and the heat exchange fan assembly has good heat exchange performance.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchange fan assembly and an air conditioner. Background technique [0002] With the rapid development of the household air conditioner industry today, users are paying more and more attention to the comfort of the air supply of the air conditioner. To better solve the problem of air supply comfort, it is necessary to start with improving the performance of the air conditioner and maximize the capacity of the heat exchanger. [0003] The prior art discloses an indoor unit of an air conditioner, which includes a bottom case on which at least two air ducts are arranged side by side; an air duct cover plate that cooperates with the bottom case and covers the at least two On the air duct, the air duct cover plate has a diversion opening corresponding to each of the air ducts; at least two centrifugal fans are respectively arranged in each of the air ducts, and are co...
