Abstract: A scroll compressor includes an orbiting scroll member, a non-orbiting scroll member, a spacing block, and an annular pressure piece. The non-orbiting scroll member is disposed on the orbiting scroll member. The spacing block has a first annular recess and at least one first through hole. The spacing block is disposed on the non-orbiting scroll member. The first through hole is located within the first annular recess and penetrates the spacing block. The annular pressure piece has a second annular recess and at least one second through hole. The second through hole is located within the second annular recess and penetrates the annular pressure piece. The annular pressure piece is accommodated within the first annular recess. One side disposed with the second annular recess of the annular pressure piece faces the spacing block. The annular pressure piece is located between the spacing block and the non-orbiting scroll member.

Abstract: A micro-channel heat exchanger module is respectively connected to a compressor and an expansion device. The micro-channel heat exchanger module includes a heat transfer tube module and a block. The block has a working fluid inlet channel, a working fluid outlet channel, a working fluid distribution chamber, a plurality of working fluid outlet openings, and a plurality of working fluid inlet openings. The working fluid inlet channel is connected to one of a compressor and an expansion device. The working fluid distribution chamber communicates with the working fluid inlet channel. The working fluid outlet openings communicate the working fluid distribution chamber with the heat transfer tube module. The working fluid inlet openings communicate the heat sink with the working fluid outlet channel. The working fluid outlet channel is connected to the other one of the compressor and the expansion device.

Abstract: A motor mechanism of DC inverter-fed compressor is disclosed, wherein a motor rotor includes a first rotor layer, a second rotor layer and a third rotor layer, made up respectively of a plurality of rotor units stacked together. The rotor units have a shaft hole in the middle and have at least one magnet slot that install a permanent magnet at every quarter surface area of the rotor units. The rotor units of the first rotor layer have a plurality of first holes at one of the quarter areas thereon, and the rotor units of the third rotor layer have a plurality of third holes, which are set up at an area opposing the first holes. The present invention can reduce the height of the compressor, the costs of parts and assembly, and increase the total efficiency of the motor and the compressor.
