Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid separators, and in particular to a gas-liquid separator. Background Technology

[0002] A gas-liquid separator is a separation device that uses centrifugal separation and wire mesh filtration to remove liquid. It mainly consists of a cylinder, cyclone separator, high-efficiency defoaming screen, and drain valve. Existing gas-liquid separator installation structures have several problems: 1. Sealing issues at interfaces and for individual components: Low-frequency and high-frequency vibrations (such as in engine compartment environments) pose a serious threat to the sealing performance of interfaces and components. When multiple components are connected by screws, the pressure on the rubber sealing rings can cause deformation of the plastic body, leading to sealing ring failure and leakage. 2. Limited installation location: Current engine compartment space is compact, and the installation location of the mounting bracket is often limited by pipes, wiring harnesses, or engine structure components, resulting in limitations on the installation angle and fixing method. Furthermore, when the gas-liquid separator is placed close to the engine or intake system, the bracket design is often forced to compromise, thus affecting separation efficiency or exacerbating the risk of vibration transmission. 3. Vibration and noise transmission issues: The gas-liquid separator is inevitably affected by the vibration of other components. When the bracket rigidity is insufficient or its natural frequency coincides with the engine vibration frequency band, resonance may be induced, leading to abnormal noise or the risk of bracket fatigue fracture. Conventional rubber bushings are prone to hardening and aging under long-term high-frequency vibration, leading to a decrease in bracket preload. Vibration energy is then transmitted through the vehicle body to the passenger compartment, significantly deteriorating NVH performance. 4. Maintenance and replacement difficulties: Some brackets are located in hard-to-reach locations (such as under the chassis), requiring the removal of other components during disassembly, increasing maintenance time. Furthermore, some brackets are custom-made for specific vehicle models, resulting in a scarcity of universal replacement parts and increased maintenance costs. 5. Design trade-offs and cost constraints: Some brackets use thin-walled or composite materials to reduce weight, sacrificing impact resistance. In some economy car models, brackets reduce reinforcing ribs to simplify the design, which can also lead to insufficient load-bearing capacity. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a gas-liquid separator in which an aluminum tube is added to both the inlet and outlet of the separator and connected to a flange, thereby extending the interface and facilitating installation, reducing the influence of other components on the installation position of the fixed bracket.

[0004] This utility model discloses a gas-liquid separator, comprising a connecting part, a baffle plate, a filter screen, mounting bolts, an end cap, a return pipe, a tank body, and foam. An end cap is connected to the top of the tank body, and a baffle plate is installed between the end cap and the tank body. A return pipe is installed on the end cap, located inside the tank body. Foam is installed outside the tank body. The connecting part is mounted on the top of the end cap via mounting bolts, and a sealing ring is provided at the interface of the connecting part. A filter screen is installed at the bottom of the return pipe, and gas molecules are located inside the connecting part. The design structure of the interface and flange connection is optimized, with an aluminum tube added in the middle. A fixed bracket improves the portability of installation, making it suitable for various complex working conditions. A return pipe is installed inside the gas-liquid separator, and centrifugal separation is achieved through rotating airflow, thereby improving separation efficiency. The inlet flow field is optimized, effectively preventing high-speed fluid from directly impacting the wall or liquid surface, which could lead to droplet splashing, breakage, and re-entrainment.

[0005] Preferably, the connection part is an integrated design of interface, flange, and fixed support. An aluminum tube is added at the inlet and outlet of the separator and connected to the flange and fixed support. The interface part is extended to facilitate installation and is suitable for various complex working conditions. The interface, flange, and aluminum tube are heat-welded together for integrated sealing, eliminating leakage paths at the source. The fixed support is welded to the flange and aluminum tube, and the corners are rounded to improve the overall accuracy of the sealing surface. The radius of the rounded corner is 5mm.

[0006] Preferably, the tank body is made of lightweight aluminum alloy material, and the pressure-bearing structure meets IP67 waterproof and dustproof standards. During assembly, the upper and lower shells are connected by threads, snaps, or welding to control the flatness of the sealing surface.

[0007] Preferably, the filter screen is made of corrosion-resistant 304L stainless steel wire, and the porosity of the multi-layer composite filter paper is in the range of 30%~50%, which enables it to intercept impurity particles larger than 50μm in the liquid refrigerant. During installation, the filter screen, return pipe, check valve and other sub-components are precisely positioned to avoid displacement that would cause airflow turbulence. Oil-resistant rubber sealing rings (such as fluororubber) or sealants (such as polyurethane) are used for sealing to ensure high temperature resistance (-0℃~150℃) and pressure resistance (≥0.5MPa).

[0008] Preferably, it also includes a mounting bracket, which is installed on the outer wall of the tank; the separator can be installed and fixed by the mounting bracket.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the connection design structure of the interface and flange is optimized, an aluminum tube is added in the middle, and the fixed bracket improves the portability of installation, thus making it suitable for a variety of complex working conditions. A return pipe is set inside the gas-liquid separator, and centrifugal separation is achieved through rotating airflow, thereby improving the separation efficiency. The inlet flow field is optimized to effectively avoid high-speed fluid directly impacting the wall or liquid surface, which would cause droplet splashing, breaking and re-entrainment.

The tank body 9 is made of lightweight aluminum alloy material, and the pressure-bearing structure meets IP67 waterproof and dustproof requirements. During assembly, the upper and lower shells are connected by threads, snaps or welding to control the flatness of the sealing surface. The filter screen 4 is made of corrosion-resistant 304L stainless steel wire, and the porosity of the multi-layer composite filter paper is 30%~50%, which enables it to intercept impurity particles larger than 50μm in the liquid refrigerant.

[0018] The extended interface facilitates installation and is suitable for various complex working conditions. The interface, flange, and aluminum pipe are heat-welded together for a unified seal, eliminating leakage paths at the source. The fixing bracket is welded to the flange and aluminum pipe, and the corners are rounded to improve the overall accuracy of the sealing surface. The radius of the rounded corner is 5mm. During installation, the filter screen 4, return pipe 8, check valve, and other sub-components are precisely positioned to avoid displacement that could cause airflow turbulence.

[0019] The main functions achieved by this utility model are as follows: 1.

A heat-welded integrated seal is used to heat-weld the interface, flange, and aluminum tube into a single seal, eliminating leakage paths, reducing process flow, and eliminating common problems such as easy loosening and failure of flange connections, easy leakage of threaded seals, and aging of gaskets. 3. The internal flow channel is designed with a return pipe to optimize the inlet flow field, effectively preventing high-speed fluid from directly impacting the wall or liquid surface, causing droplet splashing, breakage, and re-entrainment. Simultaneously, the return pipe design stabilizes the liquid surface and suppresses the influence of eddies on the internal flow field.
