Abstract

The utility model relates to a refrigerator compressor with a noise reduction structure, which comprises a compressor body and a shell for enwrapping the compressor body; a plurality of reinforced ribs are arranged on the inner wall of the shell; and the inner wall of the shell between the two adjacent reinforced ribs is depressed into a groove inwards.

Description

A kind of freezer compressor with denoising structure
(1) technical field
The utility model relates to a kind of refrigeration compressor, particularly relates to a kind of freezer compressor.
(2) background technique
Compressor mainly is suction, compression and the conveying that realizes refrigeration agent, in compressor operation, and its noise source more complicated, conclusion is got up, mainly from three major types: mechanical noise, aerodynamic noise and electromagnetic noise.The method that reduces noise at present is generally all comparatively complicated, fix a silencer more, utilize the unexpected expansion of pipeline section or contraction to cause acoustic impedance sudden change in the passage, make along the sound wave of some frequency of the purling ripple of pipeline and can't pass silencing apparatus and the reflected back source of students is gone, or improve the electric machine structure design.As open day be on December 07th, 2005 application number be 200410019404.1 hermetic motor compressor exhaust structure and silencer thereof, this structure includes compressor case, electronic and press part composition, shell between electronic and the press part is provided with outlet pipe, and the exhaust honeycomb duct is set at the exhaust side of cylinder assembly, the exhaust honeycomb duct is communicated with outlet pipe, the cold media air water conservancy diversion of discharging in outlet pipe.A kind of silencer that is used for the hermetic motor compressor exhaust structure also is provided, promptly is provided with the silencer that makes the sound attenuation band resonant cavity when discharging refrigerant, and have the exhaust honeycomb duct of certain-length and internal diameter its outlet setting in the discharge side of compression volume.Howsoever, a compressor finally still produces noise with the closed casing vibration to extraradial form, so design of shell is considerable.
(3) summary of the invention
In order to overcome the deficiency of above-mentioned technical problem, the utility model provides a kind of shell is carried out the improved freezer compressor that can reduce noise greatly.
The technical scheme in the invention for solving the technical problem is:
A kind of freezer compressor with denoising structure, the shell that comprises compressor body and coat compressor body, outer casing inner wall is provided with plurality of strengthening ribs, and stiffening rib caves inward into groove with outer casing inner wall between the stiffening rib.
After on the housing stiffening rib being set, changed the internal structure of housing, improved the rigidity and the natural frequency of housing, reduce the vibration of housing, a part of in addition acoustic irradiation is in the cavity of stiffening rib and groove composition, and part energy is cancelled out each other, thereby greatly reduces noise.The setting of groove has also reduced the material composition to offset the material that stiffening rib increases in addition.
As improvement, groove is spherical, and the degree of depth of groove is greater than the radius of the ball at spherical crown place.Its opening of shape that is groove is little, and is inner big, and after the groove of this structure, sound wave repeatedly reflected in groove, energy significantly reduced, and its radiation intensity of sound wave of revealing from opening is very little, greatly reduces noise.
Spacing between the stiffening rib is identical, and the size of each groove is all identical with the degree of depth.Stiffening rib and groove can rule be distributed in outer casing inner wall, also can irregularly be distributed in outer casing inner wall, the size of groove also can be different with the degree of depth in addition.
The beneficial effects of the utility model are: the utility model wall in the enclosure is provided with stiffening rib and groove, the rigidity and the natural frequency of shell have been improved, reduced the noise that compressor produces effectively, and do not increased material, increased surface area and made heat sinking function also improve greatly.
(4) description of drawings
Fig. 1 is a kind of sectional structure schematic representation of the utility model shell;
Fig. 2 is a kind of sectional structure schematic representation of the utility model shell.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of freezer compressor with denoising structure, comprise shell 1 and compressor body, shell coats compressor body, the inwall of shell 1 is provided with some stiffening ribs 2, and stiffening rib caves inward into groove 3 with inwall between the stiffening rib, but plurality of strengthening ribs 2 regular distribution, distance between each is identical, also can become irregular distribution.Groove 3 is spherical, and the opening of groove is less, less than the diameter of the ball at spherical crown place, as shown in Figure 2.Sound wave repeatedly reflects and cancels out each other in the chamber at stiffening rib and groove place, and energy reduces greatly, and the shell of this structure increased rigidity and improved fixed frequency, greatly reduces noise.

Claims (3)

1. freezer compressor with denoising structure comprises compressor body and the shell that coats compressor body, it is characterized in that described outer casing inner wall is provided with plurality of strengthening ribs, and stiffening rib caves inward into groove with outer casing inner wall between the stiffening rib.
2. a kind of freezer compressor with denoising structure according to claim 1 it is characterized in that described groove is spherical, and the degree of depth of groove is greater than the radius of the ball at spherical crown place.
3. a kind of freezer compressor with denoising structure according to claim 1 and 2 is characterized in that the spacing between the described stiffening rib is identical, and the size of each groove is all identical with the degree of depth.
