The embodiment of the invention provides an air channel structure of a double-air-inlet centrifugal wind wheel. The structure is used for increasing air inlets on the premise of reserving round air inlets and solving the problem that the air channel area is limited, and the newly-increased air inlets enable air to be distributed more evenly when the air flows through a heat exchanger and enters a volute, so that the phenomenon of air congregation is avoided. According to the technical scheme, the air channel structure of the double-air-inlet centrifugal wind wheel comprises the centrifugal wind wheel, a motor, the volute and a seal shell; the motor is fixed into the centrifugal wind wheel and connected with the centrifugal wind wheel; the volute is arranged outside the centrifugal wind wheel, and the volute comprises a front volute body and a rear volute body; the front volute body comprises an outer layer and an inner layer, a first air inlet is formed in the inner layer, and one or more second air inlets are formed in the outer layer; the inner layer and the rear volute body form an inner layer air channel, and the outer layer and the seal shell form an outer layer air channel.
Description
Technical field [0001] The embodiment of the present invention relates to the technical field of air conditioners, in particular to an air duct structure of a double-inlet centrifugal wind wheel. Background technique [0002] With the development of various industries such as air conditioning, centrifugal fans have become more and more widely used, among which the most widely used is the double-inlet centrifugal fan. [0003] In the existing technology, such as figure 1 As shown, the air duct structure of the centrifugal wind wheel of the air conditioner includes: a front volute 1, a rear volute 3, and a centrifugal wind wheel 4 located between the front volute 1 and the rear volute 3. Under the action of the centrifugal wind wheel 4, After the indoor air flows through the heat exchanger, it is sucked into the wind wheel by the axial air inlet end of the wind wheel, and then discharged from the air outlet by the radial direction of the blades to the volute. Therefore, the axial air...
