Abstract
The utility model discloses a parallel flow heat exchanger and an air conditioner. The parallel flow heat exchanger comprises a plurality of flat pipes and two header pipes connected with the two ends of the flat pipes, wherein the two ends of the header pipes are sealed; at least one header pipe is internally provided with partitions; and through holes are formed in the partitions. Sound waves generated by flowing noise of a refrigerant allow air in the header pipes to generate vibration and to be transmitted forwards; friction generated when the air pass through the through holes allows sound energy to be converted into heat energy; in addition, vortexes are generated near the through holes due to airflow turbulence and allow the pressure of the sound waves to be reduced so as to weaken the sound waves; and finally, the flowing noise of the refrigerant is reduced.

The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 1-parallel-flow heat exchanger of the present utility model the first embodiment shown in Figure 3, described parallel-flow heat exchanger comprises some flat tubes 200, header 100, refrigerant pipe 300, flow distribution plate 500 and has the dividing plate 400 of some through holes 410, wherein header is 100 two, is connected to flat tube 200 two ends; Header 100 two ends are by two end cap 110 sealings; Header 100 sidewalls that are connected in as shown in the figure flat tube 200 upper ends connect a refrigerant pipe 300, and the header 100 that is connected in flat tube 200 lower ends is middle by flow distribution plate 500 isolation, and respectively connects a refrigerant pipe 300 on the sidewall at two ends; Has the dividing plate 400 that radially extends at least one header 100, specifically, the sidewall of header 100 is provided with otch 120, dividing plate 400 by this otch 120 insert headers 100 inner and with its sidewall butt, become a kind of acoustical panel owing to having some through holes 410 on the dividing plate 120, as a kind of optimal way, present embodiment has all inserted dividing plate 400 in two headers 100; Header 100 is interior can to only have a dividing plate 400, and present embodiment is distributed in respectively header 100 two ends in header 100 interior insertion two dividing plates 400, dividing plate 400 and the about 20 ~ 30mm of distance that closes on header 100 ends of this dividing plate.
When refrigerant enters the right-hand member cavity of lower end header 100, the sound wave that the noise that refrigerant flows produces forces the air in the header 100 to produce vibration and propagates forward, when air passes through the through hole 410 of right-hand member dividing plate 400, produce friction and make acoustic energy be converted into heat energy with hole wall; Simultaneously near the through hole 410 because air turbulence produces whirlpool, acoustic pressure is descended and be weakened; Remaining sound wave enters in dividing plate 410 and the formed narrow and small cavity in header 100 ends, is consumed the noise that final realization reduces even the elimination refrigerant flows after the friction of cavity inner wall Multi reflection; In like manner, after refrigerant entered the header 100 of upper end, Refrigerant noise was reduced by the dividing plate 400 at header 100 two ends respectively or eliminates, enter the left end cavity of lower end header 100 after, Refrigerant noise is reduced by the dividing plate 400 of its left end or eliminates.
Referring to Fig. 4-parallel-flow heat exchanger of the present utility model the second embodiment shown in Figure 6, it is that from the maximum difference of above-described embodiment dividing plate 400 is different, has an axially extended dividing plate with holes 400 in the present embodiment at least one header 100, concrete, dividing plate 400 length are suitable with header 100 length, header 100 inwalls are provided with axially extended groove, dividing plate 400 inserts in the header 100 by this groove, present embodiment arranges two relative grooves in header 100 inwalls, more firmly is fixed in the header 100 so that dividing plate 400 both sides all are sticked in the groove; As a kind of optimal way, present embodiment has all inserted dividing plate 400 in two headers 100.Refrigerant pipe 300 is connected in the end cap 110 of header 100 ends, with convenient processing.After refrigerant entered header 100, the noise that refrigerant flows was reduced by dividing plate 400 equally or eliminates, and its principle is same as the previously described embodiments, is not giving unnecessary details at this.
Further, the dividing plate 400 among the second embodiment is vertical with flat tube 200, so that refrigerant flows out the rear through hole 410 that directly passes through dividing plate 400 from flat tube 200, Refrigerant noise is able to rapid elimination.
Further, the dividing plate 400 among above-mentioned first, second embodiment can be metallic plate or plastic plate, the preferred aluminium sheet of present embodiment, and its erasure effect is better; Dividing plate 400 thickness are advisable with 1 ~ 3mm, and through hole 410 apertures on the dividing plate 400 are preferably 1 ~ 3mm, and concrete numerical value is decided on different air-conditioners, particularly decide for the frequency of header 100 interior refrigerant hydrodynamic noises.
Present embodiment proposes a kind of air-conditioner simultaneously, it comprises a parallel-flow heat exchanger, and this parallel-flow heat exchanger comprises some flat tubes and is connected in two headers at flat tube two ends, described header closed at both ends, and have dividing plate at least one header, this dividing plate is provided with through hole.Parallel-flow heat exchanger described in the present embodiment is the related parallel-flow heat exchanger of above-described embodiment in the utility model, does not repeat them here.
Should be understood that; it below only is preferred embodiment of the present utility model; can not therefore limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
