Description

Technical Field

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

[0002] An accumulator bottle plays a key role in an automotive thermal management system, mainly used to separate gas and liquid from the refrigerant to ensure that the compressor can only suck in gas to prevent liquid refrigerant from entering the compressor and causing damage. For example, the gas-liquid separator, automotive thermal management system and vehicle proposed in the prior art publication number CN215621285U. The gas-liquid separator includes a tank body and a first end cap. The first end cap is arranged on the top of the tank body. The tank body has a receiving cavity. A first flow pipe for gaseous refrigerant to flow through is arranged in the receiving cavity. The first flow pipe has an air inlet and an air outlet. A first inlet and a first outlet are arranged on the side wall of the first end cap. The first inlet and the air inlet are both communicated with the receiving cavity, and the air outlet is communicated with the first outlet. Thus, when arranging the gas-liquid separator, the first inlet and the first outlet can be directly docked with the components in the automotive thermal management system, making the gas-liquid separator easy to integrate with other components and reducing the production and manufacturing cost. Commonly used accumulator bottles usually integrate desiccants inside the tank body. Although this design is simple, it has a significant defect: once the desiccant fails or becomes saturated, the desiccant cannot be replaced separately, and the entire accumulator bottle must be replaced, which not only increases the maintenance cost but also causes waste, especially when the tank body itself is still intact. The traditional design lacks flexibility in replacing the desiccant, restricting the maintenance efficiency of the system. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model provides a novel gas-liquid separator that reduces the later maintenance cost, improves the convenience of maintenance and the durability of the system.

[0004] A novel gas-liquid separator of the utility model includes a sealing cover, a cylinder body assembly and a drying component. The sealing cover is connected to the cylinder body assembly. A maintenance port is reserved on the sealing cover. The cylinder body assembly is internally provided with a gas-liquid separation pipeline. The drying component is installed inside the cylinder body assembly through the maintenance port. The reserved maintenance hole facilitates the easy disassembly and replacement when the desiccant fails, enabling the desiccant to be replaced separately, reducing the maintenance cost and improving the maintenance efficiency.

[0005] Preferably, the drying component includes a desiccant cylinder, desiccant, spring, and maintenance cover. The desiccant cylinder is installed inside the cylinder assembly. The desiccant is located inside the desiccant cylinder. The maintenance cover is screwed at the maintenance opening, and an O-ring seal is provided on the maintenance cover. A spring is installed between the maintenance cover and the desiccant. The spring can fix the desiccant in the desiccant cylinder to prevent shaking. By providing the desiccant cylinder, the desiccant can be encapsulated in an independent cylinder, which can be conveniently disassembled and replaced from the main cylinder. The desiccant absorbs moisture in the refrigerant to keep the system dry. Unscrewing the maintenance cover facilitates easy disassembly and replacement when the desiccant fails, enabling the desiccant to be replaced individually. The O-ring seal is responsible for radial sealing to ensure airtightness.

[0006] Preferably, a flow deflector is installed inside the cylinder assembly; the flow deflector is used to guide the flow of the refrigerant to help better separate gas and liquid, and through the flow deflector and the gas-liquid separation pipeline, the high efficiency of gas-liquid separation is ensured.

[0007] Preferably, it further includes an oil return cover and a filter screen. The oil return cover is installed at the rear of the gas-liquid separation pipeline inside the cylinder assembly, and a filter screen is installed on the oil return cover; through the oil return cover, it can be ensured that the separated oil can return to the compressor, and at the same time, the filter screen can protect the system from being blocked by large particle impurities.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: The reserved maintenance hole facilitates easy disassembly and replacement when the desiccant fails, enabling the desiccant to be replaced individually, reducing the maintenance cost, and improving the maintenance efficiency.

The desiccant 7 absorbs the moisture in the refrigerant to keep the system dry. Unscrewing the maintenance cover 9 can facilitate the easy disassembly and replacement when the desiccant fails, so that the desiccant can be replaced separately. The O-ring seal is responsible for radial sealing and can ensure airtightness. The flow dividing plate 3 is used to guide the flow of the refrigerant to help better separate the gas and the liquid. Through the flow dividing plate 3 and the gas-liquid separation pipeline, the high efficiency of gas-liquid separation is ensured. Through the oil return cover 4, it can be ensured that the separated oil can return to the compressor, and at the same time, the filter screen 6 can protect the system from being blocked by large particle impurities.

[0018] As Figures 1 to 5 shown, for a new type of gas-liquid separator of the present utility model, when it works, the maintenance cover 9 is tightened on the cover 1 by threads.
