Abstract: The scroll compressor (2) comprises a hermetic enclosure (3) comprising an outer shell (4); a compression unit (11) arranged within the hermetic enclosure (3); an electric motor (21) configured to drive the compression unit (11), the electric motor (21) including a rotor (22) and a stator (23); and an inner shell (26) in which the electric motor (21) is arranged. A baffle (34) is arranged inside the inner shell (26) at a stator end winding (25) of the electric motor (21), the baffle (34) comprising deflecting means configured to deflect at least a part of a main refrigerant flow, flowing inside the inner shell (26), towards said stator end winding (25).

Abstract: The scroll compressor (1) includes a compressor shell (2) having a discharge outlet (4); a fixed scroll (7) arranged within the compressor shell (2) and including a fixed base plate (11) and a discharge passage (16) which is formed in the fixed base plate (11) and which is provided with a discharge port (17) emerging into a discharge pressure volume (18) at least partially defined by the compressor shell (2) and the fixed scroll (7); and a deflector (29) arranged in the discharge pressure volume (18), the deflector (29) covering the discharge port (17) and at least partially delimiting a discharge opening (31) facing the discharge outlet (4) of the compressor shell (2), the deflector (29) being configured to force a compressed refrigerant gas flow emerging from the discharge port (17) to smoothly shift from an axial direction to a radial direction and being configured to direct said compressed refrigerant gas flow towards the discharge outlet (4).
