Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.
A kind of indoor set reducing air conditioner noises of the utility model, lift the indoor set used on the ceiling, it comprises casing 10 and is positioned at the turbofan 20 of casing 10 and is positioned at the heat exchanger 30 of turbofan 20 periphery, existing heat exchanger, for U-shaped heat exchanger, can certainly be back-shaped heat exchanger, straight parallel plate type heat exchanger.The heat exchanger of such indoor set has the nearest of two positions, place and turbofan 2, with the description of prior art, when heat exchanger 30 and turbofan 20 close together, because the wind speed of turbofan 20 surrounding is herein higher, when higher wind speed blows on this part region fin of heat exchanger 30, blow over from the gap between fin, be easy to the noise forming similar " whistle sound ", for reducing " whistle sound " noise of air-conditioning, on the inwall of heat exchanger 30, flow-disturbing parts are provided with in the utility model, flow-disturbing parts comprise the spoiler be obliquely installed, spoiler is positioned at the windward side of the region heat exchanger fin minimum with the spacing in turbofan 20 center of circle, the incline direction of spoiler is along the rotation direction of turbofan 20.
Concrete structure of the present utility model and operation principle is elaborated below by two specific embodiments.
Embodiment one
With reference to Fig. 2 to Fig. 5, in the present embodiment, flow-disturbing parts only comprise the spoiler 40 be obliquely installed, as mentioned above, spoiler 40 is positioned at region A heat exchanger fin (Fig. 2 minimum with the spacing in turbofan 20 center of circle, region in Fig. 3 in dotted line frame) the windward side (indoor set shown in Fig. 2 and Fig. 3, the rotation direction of its turbofan 20 is clockwise), namely when turbofan 20 operates, before air-flow blows on heat exchanger fin A, direction and the speed of air-flow is first changed by spoiler 40, the high velocity air that turbofan is blown out can not directly blow on this part fin, and then eliminate the factor producing " whistle sound " noise, then reduce " whistle sound " noise even eliminating air-conditioning.
Particularly, spoiler 40 can be formed by PP materials processing, and the tilt angle alpha between itself and the inwall of heat exchanger 30 is 100 °-130 °.Why adopt this angular range, because learn according to the wind field CFD analogue simulation analysis of indoor set, can farthest reduce the wind speed blown on the A heat exchanger fin of region on the basis taking into account heat transfer effect when spoiler 40 is in this range of tilt angles, the determination at the concrete angle of inclination of spoiler 40 should be learnt according to the analysis of CFD analogue simulation in conjunction with factors such as wind field distributions in the rotating speed of the distance of concrete type, turbofan 20 and heat exchanger 30, turbofan 20, indoor set.
Further, as shown in Figure 4 and Figure 5, the present embodiment spoiler 40 is a strip plate, its length direction is consistent with the short transverse of heat exchanger 30, a side on its length direction installs side 41 for it, another relative side is free side 42, and spoiler 40 is installed side 41 with it and is installed on the heat exchanger tube of heat exchanger 30, can adopt and clamp fixing or other fixed forms.
Preferably, install on side 41 at it and be provided with claw 43, by the mode of claw 43 by elastic deformation, spoiler 40 is installed on the heat exchanger tube of heat exchanger 30, installs simple and convenient, substantially increase production efficiency.
Owing to arranging spoiler 40, the wind speed blown on A place, region heat exchanger fin is decreased, then inherently affect heat transfer effect, because spoiler in the present embodiment 40 is a strip, width is less, the number of fins of blocking is less, for reaching the effect of reduction " whistle sound " noise, the present embodiment spoiler 40 is particularly useful for the lower indoor set that can meet heat transfer requirements of the requirement of air quantity.
Because turbofan 20 and heat exchanger 30 are positioned at the cavity that casing 10 surrounds, according to mechanical oscillation and noise basic law, noise when indoor set runs constantly can be reflected by casing 10 inner surface, can noise be amplified in the cavity that casing 10 surrounds, affect the action effect of spoiler 40.For head it off, effective solution " whistle sound " noise problem, as shown in Figures 2 and 3, be coated with sound-absorbing material in the present embodiment on the inwall of casing 10, this sound-absorbing material can be installed in acoustical cotton 60 on casing 10 inwall or other sound-absorbing materials by bonding mode.Like this, when sound wave arrives on casing 10 inwall, a part can be absorbed by sound-absorbing material, reduce the sound wave of reflection, thus the noise reflex of indoor set casing can well be improved.
Embodiment two
With reference to Fig. 6 to Fig. 8, with embodiment one unlike, in the present embodiment, flow-disturbing parts also include extension board 50 except spoiler 40, extension board 50 is positioned at the side, free side 42 place of spoiler 40, and covering the region A heat exchanger fin minimum with the spacing in turbofan 20 center of circle, extension board 50 is connected with free side 42 rounding off of spoiler 40 with a side 51 of its length direction.The shape of extension board 50 is more round and smooth better, and the connecting portion of itself and spoiler 40 also adopts rounding off, produces eddy current noise to avoid there is sharp-pointed position.
Extension board 50 can be one-body molded or connected as one by syndeton such as buckle etc. with spoiler 40, by setting up extension board 50 on the basis of spoiler 40, the area of flow-disturbing parts and volume are increased, the fin at A place, a fairly large number of region can be blocked, and then can eliminate better " the whistle sound " that blow fin, be particularly useful for the higher indoor set that could meet heat transfer requirements of air quantity requirement.
For installing firmly, to adapt to higher air quantity, another side 52 of extension board 50 length direction being provided with the claw 53 be installed on heat exchanger 30 heat exchanger tube, this side is also fixed on heat exchanger tube by the mode clamped, fixing more reliable.
Although the flow-disturbing parts that same spoiler 40 and extension board 50 are formed can be eliminated " whistle sound " better, but because the number of fins at its A place, region of blocking is more, the heat transfer effect impact of heat exchanger is larger, for making up this impact, spoiler 40 and extension board 50 are laid with through hole 44,54, fraction can be allowed to blow over spoiler 40 and extension board 50 arrives heat exchanger 30, to reduce the impact of heat exchanger heat transfer effect as much as possible.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
