DISCRETE HEAT-INSULATED EXHAUST MUFFLER DEVICE AND REFRIGERATION COMPRESSOR USING SAME

摘要

A discrete heat-insulated exhaust muffler device (8) and a refrigeration compressor using the same. The exhaust muffler device (8) comprises metal cavities (9, 10) and intake pipe and exhaust pipe installation holes respectively arranged on the metal cavities (9, 10). Non-metal cases (17, 18) are further arranged outside the metal cavities (9, 10), and the exhaust muffler device (8) is disposed outside cylinder blocks (14, 20) and is separated from the cylinder blocks (14, 20). By additionally disposing a layer of non-metal cases (17, 18) outside the metal cavities (9, 10), the chances that the exhausted air contacts air inside a compressor are reduced owing to a better heat-insulation effect of the non-metal material, thereby reducing the heat transferred from the metal cavities (9, 10) to the outside, so that the air inside the compressor has a low temperature, and the efficiency of the compressor is improved. Meanwhile, the metal cavities (9, 10) are formed through stamping, thereby reducing the material cost and weight of the device, simplifying the manufacturing process, and leaving more room at the periphery of the cylinder blocks (14, 20).
