In the prior art, the including of air-conditioner outdoor unit: axial-flow leaf, baffle liner, compressor disk, panel (panel contains grid), condenser.Outdoor air drives through axial-flow leaf, enters in the air-conditioner outdoor unit from the air-conditioner outdoor unit outside, and air arrives flow region earlier by condenser and its generation heat exchange, flows in flow region.Compressor disk is used for compressor and ducting system are kept apart, and makes the heat exchange air smooth and easy mobile in flow region, avoids compressor hot-air and heat exchange air mixed influence heat pump performance on every side.
Therefore, further improve the structure of baffle liner, can improve the performance of air-conditioner outdoor unit and reduce noise.
Summary of the invention
The purpose of this utility model is to provide a kind of baffle liner, and has the air-conditioner of baffle liner, can improve the noise tonequality of air-conditioner outdoor unit effectively.In addition, this baffle liner can play certain guide functions, makes the air-flow by the axial-flow leaf acting flow out off-premises station more smoothly, thereby improves the efficient of axial flow blower.
The utility model is achieved through the following technical solutions:
Baffle liner, described baffle liner adopts the duct type cyclic structure; The inner via hole of described baffle liner is a gas channel; Wherein, on the internal face of described gas channel, be provided with one or more disturbing flow devices.
Described disturbing flow device is a kind of bulge-structure or groove structure.
Described disturbing flow device is attached on the internal face of described gas channel, is the center with the center line of described baffle liner, presses a plurality of bulge-structures that circular array is arranged.
Described bulge-structure has the smooth streamlined outline of transition.
Described bulge-structure has the water droplet shape of arranging by airflow direction; The head of described water droplet shape is towards the outflow direction of air-flow, and the afterbody of described water droplet shape is towards the inflow direction of air-flow.
Air-conditioner with baffle liner includes panel, shell, baffle liner, axial-flow leaf and condenser; From described panel backward, each position component is arranged and is followed successively by: baffle liner, axial-flow leaf, condenser, shell; Described panel is provided with the air port, and described baffle liner is positioned at the air port rear of described panel; Described baffle liner adopts the duct type cyclic structure; The inner via hole of described baffle liner is a gas channel; Wherein, on the internal face of described gas channel, be provided with one or more disturbing flow devices.
To sum up, the beneficial effects of the utility model are:
Baffle liner of the present utility model, by the smooth bulge-structure of some transition is set on the baffle liner surface, thereby make the axial flow blower fan blade afterbody whirlpool that comes off in the process of coming off, constantly bump and destroyed, thereby thereby the whirlpool that prevents to come off further enlarge and strengthen and the bump components downstream causes noise problem with these rat structures.In addition,, air-flow also there is certain guiding function, can improves the efficient of axial flow blower because bulge-structure is in the axial-flow leaf exit.
Baffle liner of the present utility model can destroy in the air-conditioner outdoor unit axial-flow leaf afterbody whirlpool that comes off, and weakens behind the vortex shedding the impacting of baffle liner, thereby weakens the noise of axial-flow leaf, improves the noise tonequality of air-conditioner outdoor unit.In addition, baffle liner of the present utility model can play certain guide functions, makes the air-flow by the axial-flow leaf acting flow out off-premises station more smoothly, thereby improves the efficient of axial flow blower.
When baffle liner of the present utility model was applied in the air-conditioner outdoor unit that refrigerating capacity is 3200W, air quantity had the increase about 2%, and noise reduces about 1dB (A) simultaneously.
