Abstract

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.
