A deflector for a condenser. The condenser has an inlet in communication with a compressor, and a deflector for guiding a refrigerant gas flow from the compressor is arranged in the condenser and at a position close to the inlet. The deflector is provided with a deflecting structure projecting toward the inlet, and the deflecting structure is configured as impermeable to the refrigerant gas flow.

The present utility model relates to a deflector for a condenser. The condenser has an inlet in communication with a compressor, and a deflector for guiding a refrigerant gas flow from the compressor is arranged in the condenser and at a position close to the inlet. The deflector is provided with a deflecting structure projecting toward the inlet, and the deflecting structure is configured as impermeable to the refrigerant gas flow. The present utility model further provides a condenser having the deflector for a condenser and a refrigeration system equipped with the condenser. The deflector for a condenser according to the present utility model not only can alleviate the impact of high-temperature high-pressure gas from the compressor but also can reduce noise and vibration.

A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.
