Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid separator technology, and in particular to a liquid separator structure. Background Technology
[0002] The distributor head is a component installed between the throttling mechanism and the evaporator. The inlet of the distributor head is connected to the outlet pipe of the throttling mechanism, and multiple dispensing capillary tubes are welded to the outlet of the distributor head. The outlet end of the dispensing capillary tubes is connected to the evaporator. The purpose of the distributor head is to distribute the refrigerant from the throttling mechanism evenly to each process of the evaporator after it is distributed through the dispensing capillary tubes, so as to achieve uniform and equal liquid supply to the evaporator, so that the refrigerant can evaporate and absorb heat with maximum efficiency, thereby optimizing the performance of the evaporator and achieving the best cooling effect.
[0003] Currently, liquid separators are mainly classified into four types according to their liquid separation principle: pressure drop type, Venturi type, centrifugal type, and storage type. However, existing Venturi type liquid separators still have certain defects in use. Although the manufacturing process is relatively simple, only the outer part of the inlet is machined internally, resulting in low precision. Furthermore, only the inlet portion can be machined into a Venturi shape, while the internal channels are machined by drilling and rotating the head. This cannot meet the requirements of Venturi gas-liquid mixing injection, especially when the pressure inside the pipe is low, the uneven gas-liquid mixing becomes more severe, which affects the performance of the evaporator. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a liquid separator structure, which has a guide vane inside, enabling the gas and liquid to mix more evenly.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A liquid distributor structure includes a liquid distributor body and an inlet pipe connected to one end of the liquid distributor body. The bottom of the other end of the liquid distributor body is provided with a plurality of diversion holes. A diversion cone is provided inside the liquid distributor body. A spirally arranged guide vane is provided inside the inlet pipe. The guide vane can cause the medium passing through the inlet pipe to generate swirling flow.
[0006] Compared with existing technologies, this technical solution has the following technical advantages: In this application, a spiral guide vane is installed inside the inlet pipe. The guide vane can generate a swirling flow of the medium flowing in from the inlet pipe, thereby mixing the gas and liquid. This makes the flow distribution cone more uniform after the flow distribution, and makes the medium state in each capillary more uniform, ensuring uniform and equal liquid supply to the evaporator, thus ensuring the working efficiency of the evaporator. This structural design can improve the uniformity of liquid outlet from the flow distribution hole by 15%-20%.
[0007] As a further description of the above technical solution: the side wall of the guide vane is fixed to the inner wall of the inlet pipe by welding.
[0008] As a further description of the above technical solution: a Venturi structure is also provided at the rear end of the guide vane.
[0009] As a further description of the above technical solution: the length of the guide vane is 5cm-20cm, and the angle between the guide vane and the horizontal line is 30°-70°.
[0010] As a further description of the above technical solution: the guide plate is made of stainless steel or copper. Attached Figure Description

[0012] 1. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Reference Figures 1-4 One embodiment provided by this utility model: A liquid distributor structure includes a liquid distributor body 1 and an inlet pipe 2 connected to one end of the liquid distributor body 1. Multiple diversion holes 3 are provided at the bottom of the other end of the liquid distributor body 1. A diversion cone 4 is provided inside the liquid distributor body 1, and a spirally arranged guide vane 5 is provided inside the inlet pipe 2. The guide vane 5 enables the medium flowing through the inlet pipe 2 to swirl. In this application, by providing a spirally arranged guide vane 5 inside the inlet pipe 2, the medium flowing through the inlet pipe 2 can be swirled, thereby mixing the gas and liquid. This makes the diversion cone 4 more uniform after diversion, resulting in a more uniform medium state in each capillary, ensuring a uniform and equal liquid supply to the evaporator, thus guaranteeing the evaporator's working efficiency. This structural design can improve the uniformity of liquid output from the diversion holes 3 by 15%-20%.
[0014] In this embodiment, the side wall of the guide vane 5 is fixed to the inner wall of the inlet pipe by welding, which makes the fixation more secure and prevents it from falling off.
[0015] In this embodiment, a Venturi structure 6 is also provided at the rear end of the guide vane 5. In this way, the guide vane 5 and the Venturi structure 6 are combined. First, the flow is mixed through the guide vane 5, and then the flow velocity is further increased by the Venturi structure 6. This increases the flow velocity of the medium while maintaining the swirling characteristics, ensuring that the flow divider cone 4 can evenly distribute the medium to each flow divider hole 3.
[0016] In this embodiment, the length of the guide vane 5 is 5cm-20cm, and the angle between the guide vane 5 and the horizontal line is 30°-70°. This ensures sufficient swirling intensity while avoiding energy loss due to excessive rotation.
[0017] In this embodiment, the guide plate 5 is made of stainless steel or copper, which facilitates production and processing.
[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
