Technical Field

[0001] The utility model relates to the technical field of gas-liquid separators, in particular to a hot gas bypass gas-liquid separator. Background Art

[0002] The gas-liquid separator plays an important role in the automotive thermal management system, ensuring that the compressor only inhales gaseous refrigerant, thereby preventing liquid refrigerant from damaging the compressor.

[0003] Existing gas-liquid separators, such as the prior art with application number CN201420746559.4, include a gas-liquid separator cylinder, a gas-liquid separator cover, a gas inlet, a gas outlet, and a liquid storage section. Due to the different densities of gas and liquid, when the liquid flows with the gas, the liquid will be affected by gravity and produce a downward speed, while the gas still flows in the original direction. That is to say, the liquid and gas tend to separate in the gravitational field, and the downward liquid adheres to the wall surface, gathers together, and is discharged through the discharge pipe.

[0004] However, the existing technology does not have the function of replacing the desiccant, and when the desiccant fails, the entire gas-liquid separator needs to be replaced, which increases maintenance costs. In addition, in cold environments, the temperature of the separated gas is low, resulting in a significant decrease in the efficiency of the compressor. Utility Model Content
