摘要： A heat exchanger for a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a shell having an inlet configured to receive refrigerant and an outlet configured to output the refrigerant. The heat exchanger also includes a refrigerant distributor disposed within the shell, and multiple evaporating tubes disposed within the shell and positioned below the refrigerant distributor. The refrigerant distributor includes a perforated plate having multiple holes, each hole extends from a top surface of the perforated plate to a bottom surface of the perforated plate, and a center point of each hole is substantially aligned with a centerline of a respective evaporating tube.

摘要： This application provides a gas-liquid separator, including a housing assembly and a plurality of first ribs. The housing assembly has an inner side wall defining a housing accommodation cavity. The housing assembly includes an inlet, a gas outlet, and a liquid outlet, the inlet. The gas outlet, and the liquid outlet are communicated with the housing accommodation cavity. The inlet is provided on the inner side wall of the housing accommodation cavity, the gas outlet is provided above the inlet, and the liquid outlet is provided below the inlet. The plurality of first ribs are arranged on the inner side wall of the housing assembly. Each of the plurality of first ribs is arranged at an angle with respect to a height direction of the housing assembly, and each of the plurality of first ribs includes a first rib windward end and a first rib leeward end. In a flow direction of a fluid entering the housing accommodation cavity from the inlet, the first rib windward end is located upstream of the first rib leeward end. In the height direction of the housing assembly, the first rib windward end is higher than the first rib leeward end. The gas-liquid separator has a compact structure, a small overall volume, and high separation efficiency.

摘要： Provided in the present application is a gas-liquid separator. The gas-liquid separator comprises a housing and a separation cylinder assembly. The housing comprises a cylindrical housing side wall, and a first end plate and a second end plate that are located at opposite ends of the housing side wall. The housing comprises a housing inlet and an upper housing outlet, the housing inlet being provided on the first end plate, and the upper housing outlet being provided on an upper part of the housing side wall. The separation cylinder assembly is arranged in a housing accommodating cavity, and the axis of the separation cylinder assembly is arranged transversely to the axis of the cylindrical housing side wall, and the separation cylinder assembly comprises an outer cylinder and an inner cylinder arranged in the outer cylinder, with the outer cylinder being supported at the bottom of the housing side wall; and the separation cylinder assembly further comprises a separation space defined between the outer cylinder and the inner cylinder and located at an upper part of the separation cylinder assembly, a lower space located at the lower part of the separation cylinder assembly and an upper outlet located at the upper part of the separation cylinder assembly, with the separation space being in communication with the housing inlet, and the upper outlet being in communication with the separation space and the housing accommodating cavity. The gas-liquid separator has advantages such as having a high separation efficiency, low noise and a small size.
