The silencer barrel comprises a barrel body with uniform diameter and a plate body sealing and covering one end of the barrel body, and the silencer body is arranged on the plate body in a penetrating mode and is fixed on the plate body in a sealing mode. The utility model further provides an air cooled heat pump which comprises the silencer of the air cooled heat pump. The air cooled heat pump and the silencer of the air cooled heat pump solves the noise problem generated when the gas flow flowing at high speed enters a low pressure pipe line from a high pressure side in an air cooled heat pump system, the silencer of the air cooled heat pump can weaken the noise generated by the gas flow, and therefore the silencer of the air cooled heat pump reduces the disturbance and hurt brought to people, and improves the using comfortable degree of a user.
Description
Technical field
The utility model belongs to the noise control technical field, particularly a kind of air-cooled heat pump and air-cooled heat pump baffler thereof.
Background technique
Existing heat pump unit is when heating operation, and during lower than the limiting temperature moved, due to the compressor self-characteristic, too low low pressure can't guarantee the unit reliable operation when ambient temperature, and unit needs the on high-tension side gas of bypass, keeps the gettering quantity of compressor.The gas of coming from the high pressure side bypass can produce harsh noise when entering low pressure line.
The model utility content
The purpose of this utility model is to provide a kind of air-cooled heat pump baffler, is intended to solve the noise problem that produces when in air-cooled heat pump unit, swiftly flowing air-flow enters low pressure line from the high pressure side.
The utility model is achieved in that a kind of air-cooled heat pump baffler, it comprises hush pipe and stretches into the interior hush pipe of described hush pipe, described hush pipe comprises the dip section that stretches in described hush pipe, the endcapped of described dip section, offer some vents on the tube wall of described dip section, described hush pipe comprises the plate body of an end of the cylindrical shell of diameter homogeneous and the described cylindrical shell of capping, and described hush pipe is arranged on described plate body and is sealingly fastened on described plate body.
Further, the periphery full weld of the plate body of described hush pipe is connected in an end of the cylindrical shell of described hush pipe.
Further, the tube wall of described hush pipe outside full weld is connected on the plate body of described hush pipe.
Further, the plate body of described hush pipe offers through hole, and the aperture of described through hole is identical with the external diameter of described hush pipe, and described hush pipe is welded in described through hole.
Another purpose of the present utility model is to provide a kind of air-cooled heat pump, and described air-cooled heat pump comprises above-mentioned air-cooled heat pump baffler.
The utility model has solved the noise problem that produces when in the air-cooled heat pump unit, swiftly flowing air-flow enters low pressure line from the high pressure side, thereby this air-cooled heat pump baffler can weaken the noise minimizing of air-flow generation to people's interference and injury, has improved the comfort level that the user uses.

Fig. 2 is the structural representation of hush pipe of the air-cooled heat pump baffler of Fig. 1.
Fig. 3 is the structural representation of hush pipe of the air-cooled heat pump baffler of Fig. 1.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.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.
See also Fig. 1 to Fig. 3, it comprises air-cooled heat pump baffler that the utility model embodiment provides 10 hush pipe 11 and stretches into hush pipe 12 in described hush pipe 11.Described hush pipe 12 comprises the dip section 13 that stretches in described hush pipe 11.The endcapped of described dip section 13.Offer some vents 14 on the tube wall of described dip section 13.Described hush pipe 11 comprises the plate body 111 of the first end of the cylindrical shell 110 of diameter homogeneous and the described cylindrical shell 110 of capping.Described hush pipe 12 is arranged on described plate body 111 and is sealingly fastened on described plate body 111.
In the present embodiment, the structure of hush pipe 12 is straight tubes of an endcapped.Described hush pipe 12 also comprises external section 15 that is placed in outside described hush pipe 11.This external section 15 suction port 16 with standard-sized sheet makes swiftly flowing gas enter in hush pipe 11 from suction port 16.Swiftly flowing gas can only enter in hush pipe 11 by suction port 16.
The periphery full weld of the plate body 111 of described hush pipe 11 is connected in the first end of the cylindrical shell 110 of described hush pipe 11.Outside the tube wall of described hush pipe 12, full weld is connected on the plate body 111 of described hush pipe 11.Described hush pipe 12 and hush pipe 11 are by being welded to connect.
Described plate body 111 offers through hole 112.The aperture of described through hole 112 is identical with the external diameter of described hush pipe 12.Described hush pipe 12 is welded in described through hole 112.The second end relative with first end of described hush pipe 11 is the air outlet 113 of standard-sized sheet.
The working principle of air-cooled heat pump baffler 10 is take the frequency spectrum of jet noise as foundation, and baffler 10 directly is installed on the ingress that bypass flow enters the major cycle pipeline, and swiftly flowing gas enters in hush pipe 11 by the vent 14 of hush pipe 12.If keep the gross area of spout constant and replace with a lot of little spouts, when air-flow during through vent 14, the frequency spectrum of jet noise will shift to high frequency or ultra-high frequency, the audible sound composition in frequency spectrum is obviously reduced, thereby can weaken the noise of air-flow generation.Gas enters the rear flow velocity of hush pipe 11 by vent 14 to be reduced greatly, can not produce new noise again, and last air-flow enters systemic circulation by the air outlet 113 of hush pipe 11.
The utility model has solved the noise problem that produces when in the air-cooled heat pump unit, swiftly flowing air-flow enters low pressure line from the high pressure side, thereby this air-cooled heat pump baffler 10 can weaken the noise minimizing of air-flow generation to people's interference and injury, has improved the comfort level that the user uses.
The utility model also provides a kind of air-cooled heat pump, and it comprises above-mentioned air-cooled heat pump baffler 10.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
