Abstract
The invention discloses an exhaust muffler and a refrigerating compressor. The refrigerating compressor comprises a housing, a core and the exhaust muffler, wherein the exhaust muffler comprises a muffler body in which a muffling cavity is formed; a refrigerant inlet and a refrigerant outlet which are communicated with the muffling cavity are formed in the muffler body; the muffler body comprises an inner wall and an outer wall; an insulation gap for wrapping the muffling cavity is formed between the inner wall and the outer wall; the exhaust muffler and a cylinder seat are individually arranged. According to the refrigerating compressor, the exhaust muffler is arranged to be a double-layer structure; the heat gap for wrapping the muffling cavity is formed between the inner wall and the outer wall, so that the air of which the heat is transmitted from the inner part of the exhaust muffler to the inner cavity of the compressor can be reduced; the exhaust muffler and the cylinder seat are individually arranged, thus the direct heat transfer due to integral casting of the exhaust muffler and the cylinder seat in the traditional technical scheme can be further reduced, and as a result, the heat exchanger from the exhaust system to the air intake system can be reduced; the performance of a refrigerator compressor can be improved, and the service life can be prolonged.

Technical field
The present invention is used for technical field of refrigeration compressors, particularly relates to a kind of muffler and refrigeration compressor.
Background technique
Refrigeration compressor, particularly freezer compressor, exhaust system temperature is high especially, and the inhalation temperature of freezer compressor is very low, therefore there is the very large temperature difference between vent systems and suction system, heat is easy to be delivered to suction system from vent systems, is unfavorable for the lifting of freezer compressor performance.The vent systems of traditional compressor and cylinder holes are made on same cylinder seat by casting technique, and metal heat transfer efficiency is high, and a large amount of heats has been delivered to suction system from vent systems.Newer corrective measure is, independent for the muffler of vent systems, is formed one " exhaust noise silencing bag ", then between vent systems and suction system no longer based on intermetallic heat trnasfer, but based on the thermaltransmission mode of gaseous exchange.But even so, " exhaust noise silencing bag " self-temperature is very high, is also easy to whole compressor inner chamber gas to be heated to higher temperature, and then is sucked high-temperature gas by air suction silencer, be unfavorable for the raising of compressor efficiency.Meanwhile, because compressor inner chamber gas temperature is high, also improve the temperature of motor winding, easily cause motor to burn machine, be unfavorable for protection compressor working life.
Summary of the invention
For solving the problem, the invention provides and a kind ofly reduce the heat transmission of vent systems to suction system, improving freezer compressor performance, and the muffler increased the service life and refrigeration compressor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of muffler, comprise the inner baffler body forming silencing cavity, described baffler body is provided with the refrigerant inlet and refrigerant outlet that are conducted with described silencing cavity, described baffler body comprises inner and outer wall, forms the heat insulation gap wrapping described silencing cavity between described inner and outer wall.
Be further used as the improvement of technical solution of the present invention, described heat insulation gap is airtight vacuum chamber.
Be further used as the improvement of technical solution of the present invention, described inner and outer wall is coated with mercury layer at the internal surface of described vacuum chamber.
Be further used as the improvement of technical solution of the present invention, described heat insulation inner space is filled with thermoinsulation material.
Be further used as the improvement of technical solution of the present invention, described thermoinsulation material is adiabatic molecular sieve.
Be further used as the improvement of technical solution of the present invention, described baffler body is metallic article.
Be further used as the improvement of technical solution of the present invention, described cryogen import and refrigerant outlet lay respectively at the two ends of described silencing cavity, and the cross section of described silencing cavity is rounded, and the two ends of described silencing cavity are heaved laterally in dome-shaped.
A kind of refrigeration compressor, comprise shell, movement and above-mentioned muffler, described movement comprises stator, rotor, cylinder block, the cylinder be contained on described cylinder block, the piston be contained in described cylinder, connecting rod with crankshaft and piston described in the bent axle of described rotor synchronous axial system and transmission, suction port and relief opening is provided with described cylinder conducting, described muffler and described cylinder block split are arranged, and the refrigerant inlet of muffler is connected with described relief opening by pipeline.
Beneficial effect of the present invention: the present invention redesigns muffler, first muffler is set to the double layer construction comprising inner and outer wall, form the heat insulation gap wrapping inner silencing cavity between inner and outer wall, and then reduce heat from muffler internal delivery to the gas of compressor inner chamber by heat insulation gap; Secondly, in the present invention, muffler and cylinder block adopt split design, be connected by pipeline between muffler with cylinder block, thus reduce further in conventional solution due to direct heat transmission that muffler and cylinder block integrally casting bring, final minimizing vent systems is to the exchange heat of suction system, improve freezer compressor performance, and increase the service life.
