Description

Technical Field

[0001] This utility model relates to a built-in oil separator. Background Technology

[0002] In vapor compression refrigeration systems, the compressed refrigerant vapor is in a high-temperature, high-pressure, and high-speed state. The refrigerant, along with lubricating oil vapor and oil droplets, is discharged from the compressor. When the lubricating oil enters the condenser and evaporator along with the refrigerant, it forms an oil film on the heat transfer walls, increasing thermal resistance and thus reducing the heat transfer efficiency of the condenser and evaporator. Therefore, an oil separator is usually installed between the compressor and the condenser to separate the lubricating oil carried in the compressor discharge gas, reducing the oil content in the unit's exhaust and the amount of lubricating oil in the unit.

[0003] In existing oil separators, the specific internal temperature of the oil separator cannot be obtained when separating lubricating oil and refrigerant, which affects the separation efficiency of lubricating oil and refrigerant. At the same time, as the temperature rises, it will cause heat overload and damage to the equipment, reducing the service life of the oil separator. Utility Model Content

[0004] The purpose of this invention is to provide a technical solution with a built-in oil separator to address the shortcomings of existing technologies. This solution not only allows for real-time monitoring of the internal temperature of the oil separator, but also enables the adjustment of the internal temperature of the oil separator through heat exchange tubes based on the detected temperature. This prevents the equipment from overheating and being damaged due to temperature rise, and extends the service life of the oil separator.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A built-in oil separator, including

[0007] A housing with an arched structure and an air intake pipe at the top;

[0008] A bottom groove plate is welded to the bottom of the shell, and an oil return assembly is provided between the bottom groove plate and the shell;

[0009] And a side sealing plate, which is located between the bottom groove plate and the shell, and has an exhaust port to form a separation cavity;

[0010] Its features are:

[0011] It also includes a temperature control component, which consists of a temperature sensor and heat exchange tubes. The temperature sensor is located on the inner wall of the shell, and the heat exchange tubes are located on the bottom plate. Both the inner surfaces of the shell and the bottom plate are provided with insulation layers. Through the design of the above structure, not only can the internal temperature of the oil separator be monitored in real time, but the internal temperature of the oil separator can also be adjusted according to the detected temperature through the heat exchange tubes. This avoids the equipment from overheating and being damaged due to temperature rise, and extends the service life of the oil separator.

[0012] Furthermore, the oil return assembly includes an oil outlet and an oil return pipe. The oil return pipe is connected to the bottom plate and the housing through the oil outlet. Through the design of the oil return pipe, the separated lubricating oil can be discharged from the oil return pipe and flow back to the compressor's exhaust port to prevent the compressor from running out of oil.

[0013] Furthermore, the housing is equipped with a first oil collecting plate and a second oil collecting plate, which are located close to the return oil pipe. The design of the first and second oil collecting plates can prevent backflow at the oil outlet and improve the stability of the conveying process.

[0014] Furthermore, both the first and second oil collecting plates have an L-shaped structure.

[0015] Furthermore, a filter assembly is provided between the housing and the bottom plate. The filter assembly includes a filter baffle and a filter screen. The filter baffle is vertically connected to the housing and the bottom plate, and the filter screen is welded between the housing and the filter baffle and adheres to the inner wall of the housing. Through the design of the above structure, the refrigerant can pass through while the lubricating oil is blocked and thus filtered out.

[0016] Furthermore, it also includes an air baffle, which is located within the separation chamber and between the filter assembly and the side sealing plate.

[0017] Furthermore, a baffle is provided at the outlet end of the intake pipe, and a notch is provided on the side of the outlet end of the intake pipe near the baffle, which facilitates the introduction of refrigerant mixed with lubricating oil into the housing along the notch.

[0018] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0019] This invention can not only monitor the internal temperature of the oil separator in real time, but also adjust the internal temperature of the oil separator through the heat exchange tube according to the detected temperature, so as to avoid the equipment from overheating and being damaged due to temperature rise, and extend the service life of the oil separator.
