Description

Technical Field

[0001] The present invention relates to the technical field of liquid separation structures, and in particular to a liquid separation structure and a heat exchange component having the same. Background Art

[0002] In current refrigeration systems, two-phase refrigerant, after throttling by the expansion valve, is distributed to different flow paths of the evaporator by a liquid separator. During this process, the gas and liquid phases separate, causing uneven refrigerant distribution. The rationality of the liquid separator design determines the uniformity of refrigerant flow distribution across different flow paths, which in turn affects the performance of the refrigeration system.

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] like Figures 1 to 8 As shown, embodiment 1 of the present invention provides a liquid separation structure, which includes a first liquid separation shell 10 and a second liquid separation shell 20. The first liquid separation shell 10 has a liquid inlet 111, a connecting port 121 and a first liquid separation cavity connected to the liquid inlet 111 and the connecting port 121. The liquid inlet 111 is arranged opposite to the first liquid separation cavity, and the connecting port 121 is arranged between the liquid inlet 111 and the first liquid separation cavity. The second liquid separation shell 20 has an installation cavity, at least part of the first liquid separation shell 10 is installed in the installation cavity, the part of the first liquid separation shell 10 located in the installation cavity is spaced apart from the inner wall of the installation cavity to form a second liquid separation cavity, and the connecting port 121 is connected to the second liquid separation cavity. Among them, the second liquid separation shell 20 is provided with a liquid separation port 223 at one end away from the connecting port 121, and the liquid separation port 223 is connected to the second liquid separation cavity. Specifically, the liquid separation structure in this embodiment not only mixes and diverts liquids, but the liquid separation structure can also mix and divert mixed fluids of liquids and gases.

[0047] With the liquid separation structure provided in this embodiment, after the liquid enters through the liquid inlet 111, it collides with the inner wall of the first liquid separation chamber to increase the mixing uniformity of the fluid in the first liquid separation chamber. The liquid in the first liquid separation chamber then enters the second liquid separation chamber through the communication port 121 for further mixing to further increase the uniformity of the mixed distribution, and finally flows out through the liquid separation port 223. Therefore, the liquid separation structure provided in this embodiment can solve the technical problem of uneven liquid separation in the liquid separation structure of the prior art.

[0048] Specifically, the communication port 121 may be disposed in the second liquid separation chamber so that the communication port 121 is in communication with the second liquid separation chamber.

[0049] In this embodiment, the first liquid separation housing 10 includes a liquid inlet housing section 11, a connecting housing section 12, and a mixing housing section 13, which are connected in sequence. At least a portion of the liquid inlet housing section 11 extends out of the mounting cavity. A liquid inlet port 111 is formed at the end of the liquid inlet housing section 11 away from the connecting housing section 12. A connecting port 121 is provided on the side wall of the connecting housing section 12. The mixing housing section 13 is used to enclose the first liquid separation cavity. Both the connecting housing section 12 and the mixing housing section 13 are disposed within the mounting cavity. This structural arrangement optimizes the structural layout, simplifies the structure, improves liquid mixing, and ensures uniform liquid separation.

[0050] Specifically, the communication shell segment 12 is annular in structure and has multiple communication openings 121, which are spaced apart along the circumference of the communication shell segment 12. This structural arrangement facilitates the flow of liquid in the first liquid separation chamber through the multiple communication openings 121 into the second liquid separation chamber for mixing, resulting in a good mixing effect and improved uniformity in liquid separation.

[0051] In this embodiment, the mixing shell segment 13 includes a first side plate 131 and a first end plate 132 that are interconnected. The first side plate 131 and the first end plate 132 enclose a first liquid separation chamber. The first side plate 131 is connected to the connecting shell segment 12, and the first end plate 132 is disposed at the end of the first side plate 131 away from the connecting shell segment 12. The flow cross-section enclosed by the first side plate 131 gradually decreases along the distribution direction from the connecting shell segment 12 to the mixing shell segment 13. This structural arrangement can increase the mixing speed, thereby improving mixing uniformity and thus improving liquid separation uniformity.

[0052] Specifically, the second liquid-separating housing 20 has an installation opening that communicates with the installation cavity. The first liquid-separating housing 10 also includes a sealing cover plate 14, which is disposed within the communicating housing section 12 and protrudes from the sidewall of the communicating housing section 12. The sealing cover plate 14 conforms to the shape of the installation opening and seals the installation opening. This structural arrangement facilitates effective sealing and plugging of the installation opening by the sealing cover plate 14.

[0053] In this embodiment, the second liquid separation housing 20 includes a first shell segment 21 and a second shell segment 22 connected to each other. The first shell segment 21 is arranged opposite the connecting shell segment 12, and the first shell segment 21 and the connecting shell segment 12 are spaced apart. The second shell segment 22 is arranged opposite the mixing shell segment 13, and the second shell segment 22 and the mixing shell segment 13 are spaced apart. With this structural arrangement, the gap between the first shell segment 21 and the connecting shell segment 12 and the gap between the second shell segment 22 and the mixing shell segment 13 can be easily formed into a second liquid separation chamber.

[0054] Specifically, the shape of the inner wall of the first shell section 21 is adapted to the shape of the outer wall of the communicating shell section 12 to facilitate liquid discharge and mixing.

[0055] Specifically, the shape of the inner wall of the second shell segment 22 is adapted to the shape of the outer wall of the mixing shell segment 13 , so as to facilitate better mixing of the fluids in the second liquid separation chamber.

[0056] In this embodiment, the connecting shell section 12 is a first annular shell, the first shell section 21 is a second annular shell, and the connecting shell section 12 is located in the middle of the first shell section 21. This structural arrangement allows for a gap to be created around the edges of the connecting shell section 12 and the first shell section 21, thereby facilitating smooth liquid discharge through the connecting port 121.

[0057] Specifically, the symmetry axis of the communicating shell segment 12 is arranged to coincide with the first shell segment 21 .

[0058] In this embodiment, the second shell segment 22 includes a second side plate 221 and a second end plate 222 that are interconnected. The second end plate 222 is disposed on a side of the second side plate 221 away from the first shell segment 21, and the liquid separation port 223 is disposed on the second end plate 222. The flow cross-section defined by the second side plate 221 gradually decreases along the direction extending from the first shell segment 21 to the second shell segment 22. This structural arrangement facilitates a gradual increase in the flow velocity of the fluid within the second liquid separation chamber along the direction extending from the first shell segment 21 to the second shell segment 22, thereby effectively improving the uniformity of fluid mixing.

[0059] Specifically, the mixing shell segment 13 includes a first side plate 131 and a first end plate 132, which are connected to each other. The first end plate 132 is disposed at the end of the first side plate 131. Along the extension direction from the connecting shell segment 12 to the mixing shell segment 13, the flow cross-section enclosed by the first side plate 131 gradually decreases, and the shape of the second side plate 221 matches the shape of the first side plate 131. This structural arrangement facilitates a gradual increase in the flow velocity of the fluid within the first side plate 131 along the extension direction from the connecting shell segment 12 to the mixing shell segment 13, thereby effectively improving the uniformity of fluid mixing within the first liquid separation chamber.

[0060] Specifically, the first side plate 131 is a first conical plate with a simple structure and good mixing effect.

[0061] Specifically, the second side plate 221 is a second conical plate with a simple structure and good mixing effect.

[0062] In this embodiment, the liquid separation port 223 is disposed opposite to the gap between the first side plate 131 and the second side plate 221 , so as to better allow the evenly mixed fluid to flow out.

[0063] Specifically, in this embodiment, there are multiple liquid separation ports 223 , and the multiple liquid separation ports 223 are arranged around the first end plate 132 to better improve the uniformity of liquid separation.

[0064] Furthermore, the liquid separation structure further includes a liquid outlet pipe 30, which is disposed outside the second liquid separation housing 20 and connected to the liquid separation port 223. This structural arrangement facilitates connection with other pipelines to be connected through the liquid outlet pipe 30.

[0065] By adopting the liquid separation structure provided by the present invention, by arranging a mixing shell section 13 in the flow direction of the refrigerant, the high-speed refrigerant is evenly broken up after vertically colliding with the mixing shell section 13, flowing in all directions, and entering the second liquid separation cavity that is 360° fully connected. The refrigerant is further mixed in the second liquid separation cavity, and the flow distribution is uniform. At the same time, after the refrigerant enters the second liquid separation cavity, the flow channel area gradually shrinks, the speed of the gas-liquid two-phase fluid gradually increases, and the control flow type is fully developed into a mist flow in the flow channel. At this time, the gas-liquid two-phase fluid is evenly mixed. The evenly distributed refrigerant flow, coupled with the evenly mixed gas-liquid phase fluid, allows the refrigerant to be evenly distributed to each liquid outlet pipe 30. The liquid separator of the present invention can evenly distribute the refrigerant, has a simple and reliable structure, low resistance, no fine structure, no clogging problem, good machinability, and has practical application value.

[0066] In this embodiment, the liquid separation structure utilizes impact-type separation, with the high-speed fluid vertically impacting the mixing shell 13, rapidly dispersing to all sides and achieving uniform flow distribution. The second liquid separation chamber provides a 360° through-flow distribution channel, further mixing the refrigerant within the second liquid separation chamber. The second liquid separation chamber's tapering cross-section increases the velocity of the gas-liquid two-phase flow, allowing the two-phase flow to fully develop into a mist flow within the flow channel. A mist flow is the ideal state for uniform mixing of the two-phase fluid.

[0067] Specifically, the sidewall of the sealing cover plate 14 is welded to the inner surface of the cylindrical first housing to achieve a sealed connection. The liquid outlet pipe 30 is also welded to the liquid outlet hole on the second end plate 222. The first and second liquid outlet housings 10 and 20 are assembled to form a second liquid outlet chamber with a 360° through-flow distribution channel.

[0068] The liquid inlet shell section 11 is connected to the expansion valve through a copper tube. The side wall surface of the sealing cover plate 14 is welded and fixed to the inner surface of the first shell of the cylindrical structure to play a sealing and fixing role. The connecting shell section 12 includes a plurality of support columns, and a connecting port 121 is formed between two adjacent support columns. The plurality of support columns connect the liquid separation plate and the upper cover plate to play a fixing role. The support columns adopt a streamlined structure to reduce flow resistance and are not limited to a cylindrical shape. The upper surface of the mixing shell section 13 is connected to the support columns, and the bottom of the mixing shell section 13 has a first end plate 132, and the first side plate 131 is in seamless sealing contact with the first end plate 132. The difference between the diameter of the first end plate 132 and the diameter of the second end plate 222 is the diameter of the connecting port 121, so that the flow channel width is basically equal to the diameter of the liquid outlet hole, which is convenient for better improving the uniformity of the liquid outlet.

[0069] The inner diameter of the first shell is equal to the inner diameter of the second shell near the first shell, and the outer diameter of the first shell is greater than or equal to the outer diameter of the second shell, so as to play a reinforcing role in the structure.

[0070] The refrigerant enters the liquid distributor from the liquid inlet shell section 11. The high-speed refrigerant vertically impacts the first side plate 131 of the connecting shell section 12. It then rapidly disperses evenly in all directions, flows through the support column, and enters the second liquid separation chamber of the 360-degree, fully through-flow distribution channel. The two-phase refrigerant continues to mix and flow within the distribution channel. Along the flow direction, the channel cross-section gradually decreases, the velocity of the gas-liquid two-phase fluid gradually increases, and the two-phase flow pattern fully develops within the channel, forming a mist flow with a uniform gas-liquid mixture. The mist flow is evenly distributed to each liquid outlet pipe 30 through the connecting port 121 and enters the different flow paths of the evaporator.

[0071] A second embodiment of the present invention provides a heat exchange assembly, which includes the liquid separation structure and a heat exchanger provided in the above embodiment, wherein the heat exchanger is connected to the liquid separation structure.

[0072] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: solving the poor uniformity of refrigerant distribution in the liquid separator and improving the heat exchange performance of the evaporator; solving the problems of poor distribution uniformity, large pressure drop or easy clogging in the existing liquid separator to varying degrees; solving the method of solving the uneven distribution of refrigerant in each flow path of the evaporator resulting in a decrease in heat exchange performance, usually by increasing the heat exchange area of ​​the evaporator and adding unnecessary costs.
