Embodiment 1

[0014] Example 1, such as figure 2 Shown: a double-cylinder rotary compressor, the compressor includes a first cylinder 1, a second cylinder 2 and a partition 3 arranged between the first and second cylinders 1, 2, the first and second cylinders 1 , 2 are respectively provided with the first and second rotary compression units 5, 6 driven by the axial rotation of the motor 4; 31 and 32 are sandwiched to form a partition 3 , and a hollow cavity 7 is provided between the first and second metal sheets 31 and 32 . The hollow cavity 7 can be formed in various ways. As a special embodiment of the present invention, the inner and outer edges of the first metal sheet body 31 and the second metal sheet body 32 are respectively provided with convex ring edges 34. After the two metal sheet bodies are clamped, the inner and outer edges The convex ring 34 forms an annular groove, and the annular groove forms the hollow cavity 7 . As a person skilled in the art, there are many technical ...

Abstract

The invention relates to the technical field of refrigeration compressors, in particular to a duplex-cylinder rotary compressor. The duplex-cylinder compressor of the invention comprises a first cylinder, a second cylinder and a partition board, wherein the partition board is arranged between the first cylinder and the second cylinder; a first rotary compression unit and a second rotary compression unit which are axially and rotatably driven by a motor are arranged in the first cylinder and the second cylinder respectively; and a hollow chamber is arranged in the partition board. The duplex-cylinder compressor of the invention has the advantages of reducing heat transfer capability, saving the solid partition board used by the conventional duplex-cylinder compressors and greatly reducing heat transfer between a compression chamber and a suction chamber on the two sides of the partition board of the compressor due to the hollow chamber arranged in the partition board, and compared with the duplex-cylinder compressor in the prior art, improving the refrigerating capacity, reducing the power consumption of the motor and improving the energy efficiency.

Description

technical field [0001] The invention relates to the technical field of refrigeration compressors, in particular to a double-cylinder rotary compressor. Background technique [0002] The refrigeration compressor is the core equipment for compressing the refrigerant in the refrigerator and air-conditioning system to make it participate in the cycle. The liquid separator is one of the important parts of the compressor (especially the rotary compressor). The rotary compression unit can effectively reduce the eccentric effect of the compression unit, so it is widely used; the double-cylinder compressor generally includes the first cylinder 1, the second cylinder 2 and the first and second cylinders 1 and 2. Between the partitions 3 (see figure 1 ), the first and second cylinders 1 and 2 are respectively provided with the first and second rotary compression units 5 and 6 driven by the axial rotation of the motor 4; On both sides, when the compressor unit of one of the cylinders ...
