Description
Technical field
The present invention is used for compressor field, more particularly to a kind of compressor air-discharging muffler.
Background technology
Traditional compressor is provided with muffler (22), is connected by air inlet pipeline (21) with movement (3), passes through exhaust
Pipeline (23) is connected with lower casing (1), forms the current path of exhaust, plays a part of muffler.It is right during compressor operating
Gas is compressed.After gas is compressed, temperature is significantly raised, and produces very high delivery temperature, compressor gas
Temperature is then relatively low, forms a thermograde.Muffler (22) largely passes heat by modes such as heat transfer, free convections
It is delivered among compressor internal gas.Simultaneously as muffler (22) position is relatively low, the freezing splashed during compressor operation
Machine oil is constantly splashed on muffler (22), is then flowed back in housing.Because refrigerator oil temperature is relatively low, exhaust is adhered to
The heat of muffler (22) above is absorbed after on muffler (22).In this case, muffler (22)
Heat is largely remained in inside compressor, is not discharged outside compressor, is improved compressor air suction temperature, is reduced compressor
Efficiency.Simultaneously as compressor internal temperature is high, easily cause motor to burn machine, be unfavorable for protecting the service life of compressor.
The content of the invention
To solve the above problems, the present invention, which provides one kind, can reduce compressor internal temperature, while keeping silencing function
Compressor air-discharging muffler.
The technical solution adopted for the present invention to solve the technical problems is：A kind of compressor air-discharging muffler, including provided with
The cavity (32) of air inlet pipeline (31) and gas exhaust piping (33), cavity (32) shape between air inlet pipeline (31) and gas exhaust piping (33)
Into silencing cavity, cavity (32) is formed by being sealed with certain thickness thin walled metallic materials, and the cavity (32) is arranged on compression
In machine shell, the shell includes upper casing (2) and lower casing (1).
The improvement of technical solution of the present invention is further used as, cavity (32) is arranged on the upper end inner surface of upper casing (2), chamber
The upper surface shape of body (32) and upper casing (2) inner surface configuration are similar.After installation, the upper surface of cavity (32) and upper casing (2) are interior
Fit completely on surface.
The improvement of technical solution of the present invention is further used as, the lower surface of cavity (32) is equidistant by the upper surface of cavity (32)
From skew generation, the distance of lower surface each point to upper surface is equal.
Be further used as the improvement of technical solution of the present invention, air inlet pipeline (31) if geometry by some straightways with
Dry transition arc bending is constituted, and the geometry of gas exhaust piping (33) is by some straightways and several transition arc bending structures
Into.
The improvement of technical solution of the present invention is further used as, cavity (32) is a profile and upper casing (2) inner surface configuration
The similar cavity being fully sealed, air inlet pipeline (31) and gas exhaust piping (33) are arranged on cavity (32), form an air-flow
Path, cavity (32) is arranged on the upper end of upper casing inner surface, and cavity (32) is connected by air inlet pipeline (31) with movement (3), chamber
Body (32) is connected by gas exhaust piping (33) with lower casing (1).
Beneficial effects of the present invention：In this compressor air-discharging muffler, cavity (32) profile and upper casing inner surface are similar, peace
Fitted completely with upper casing inner surface after dress.The high temperature of cavity (32) is directly delivered on upper casing (2).Due to cavity (32) and upper casing
(2) all it is made up of metal material, heat transfer efficiency between the two is very high, can rapidly reduces the temperature of cavity (32).Due to upper
Shell (2) external surface area is big, is directly contacted with surrounding air, good heat dissipation effect, good cooling effect is played to cavity (32).By
In cavity (32) position in the upper end of whole compressor inner chamber, the refrigerator oil splashed during compressor operating is difficult to be splashed to cavity
(32) on, therefore the heat exchange of refrigerator oil is also greatly reduced.Simultaneously as the lower surface of cavity (32) is by the upper of cavity (32)
The equidistant skew generation in surface, the space curved surface geometry of lower surface is similar to upper casing, maintains the original housing of compressor and sets
The noise radiation characteristic of meter, the noise level of compressor complete machine is not influenceed.Resultant effect is that cavity (32) is greatly reduced, compressor
Internal temperature is greatly reduced, and compressor air suction temperature is greatly reduced, and compressor performance is larger to be improved, and compressor service life is obtained
Preferably ensure, while keeping good noise level.
