Oil separation device for condenser, condenser having it and refrigeration system

An oil separation device for a condenser, the condenser comprising:

• a housing having an accommodating chamber;
• and an oil separation partition arranged inside the housing and extending along a length direction of the housing, where the oil separation partition divides the accommodating chamber into an oil separation chamber and a condensation chamber, and the oil separation chamber has a first end and a second end along its length direction, wherein the oil separation device comprises:
• a first refrigerant inlet port and a second refrigerant inlet port, arranged on the housing for guiding refrigerant gas into the oil separation chamber;
• and
• a first refrigerant outlet port, a second refrigerant outlet port, a third refrigerant outlet port, and a fourth refrigerant outlet port, arranged on the housing for guiding refrigerant gas separated from oil out of the oil separation chamber,
• wherein, the first refrigerant outlet port is arranged at the first end of the oil separation chamber, the second refrigerant outlet port is arranged at the second end of the oil separation chamber, the third refrigerant outlet port is arranged in a middle of the oil separation chamber, while the first refrigerant inlet port is arranged between the first refrigerant outlet port and the third refrigerant outlet port, and the second refrigerant inlet port is arranged between the second refrigerant outlet port and the third refrigerant outlet port, wherein the fourth refrigerant outlet port is arranged in the middle of the oil separation chamber, and the third refrigerant outlet port and the fourth refrigerant outlet port are symmetrically arranged relative to a centerline of the oil separation chamber.
