Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger-related equipment, and more specifically to a uniformly distributed flow channel structure and a plate-type flow divider using this structure. Background Technology

[0002] In existing refrigeration equipment and other equipment, such as various evaporators, heat exchangers typically have a multi-hole distribution head on one side of the main body. This head has one inlet and multiple outlets. All outlets are connected to the corresponding inlets of the heat exchange tubes of the evaporator via connecting pipes. The distribution head is conical in shape. Then, one end of multiple copper tubes is connected to the outlet, and the other end is connected to the corresponding inlet of the heat exchange tube. This structure is large in size and located on one side of the main body, occupying a lot of external space. Its performance is not ideal, especially in some indoor air conditioning equipment. Installing this structure makes it occupy too much space, increasing the size of the indoor unit and taking up too much indoor space. The effect is not ideal. Moreover, due to the placement of the distribution head, it is impossible to guarantee that the material coming out of each outlet is consistent. For example, when placed horizontally, the material output from the upper part is definitely not as fast as that from the lower part.

[0003] Therefore, existing distributors employ cylindrical structures to reduce space and improve distribution efficiency, such as... Figure 1 As shown, by narrowing the lower liquid inlet, the refrigerant mixture can be transported upward along the vertical channel in the middle as much as possible. This ensures that the gas-liquid mixture coming out of the through holes formed on the side wall of the vertical channel can be discharged evenly, improving uniformity. However, its uniformity is still limited. Under the influence of gravity in a vertical state, the uniform discharge is still limited.

[0004] Another method uses a main pipe that branches into two channel pipes, and then the two channel pipes each flow through two branch pipes to form a four-channel pipe. The material is then discharged from the outlet end of the channel pipe, achieving equal distribution. This step-by-step equal distribution method can only distribute the material evenly to a number of outlets that is 2 to the power of N. When the number of outlets is not 2 to the power of N, this method cannot meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a uniform flow channel structure and a plate-type flow divider using this structure. It can evenly distribute the material entering the main feed channel to the discharge ends at a number that is not a power of 2, ensuring that the amount of material discharged from all discharge ends is basically the same, thus greatly improving the flow diversion effect.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A uniformly distributed flow channel structure includes a main feed channel, the outlet of which is connected to the middle of a first vertical channel, one end of the first vertical channel is connected to one end of a first transverse channel, and the other end of the first vertical channel is connected to one end of a second transverse channel.

[0008] The other end of the first transverse channel is connected to the first channel group, and the other end of the second transverse channel is connected to the second channel group. The final discharge end of the first channel group is an even number, and the first transverse channel is a horizontal straight channel. The final discharge end of the second channel group is an odd number other than 1, and the second transverse channel is an inclined channel. The total feed channel is an inclined channel.

[0009] Alternatively, the final discharge end of the first channel group is an odd number other than 1, the first transverse channel is an oblique channel, the final discharge end of the second channel group is an odd number other than 1, the second transverse channel is an oblique channel, the final discharge end number of the second channel group is the same as the final discharge end number of the first channel group, and the total feed channel is a horizontal straight channel.

[0010] Alternatively, the other end of the first transverse channel can be connected to the first channel group, the final discharge end of the first channel group is two, the other end of the second transverse channel is the discharge end, and the first transverse channel is a horizontal straight channel.

[0011] A plate-type distributor with a uniformly divided flow channel structure includes a main vertical channel plate. A transversely extending main feed channel is formed in the middle of the main vertical channel plate. The right end of the main feed channel is the feed inlet. The left end of the main feed channel is connected to the middle of a first vertical channel. The first vertical channel is formed in the middle of the main vertical channel plate. The upper and lower ends of the first vertical channel are respectively connected to the left ends of the horizontal straight extensions formed on the left ends of the first and second transverse channels formed on the main vertical channel plate. The other end of the first transverse channel is connected to a first channel group, and the other end of the second transverse channel is connected to a second channel group.

[0012] The first channel group and the second channel group have the same structure, and their final discharge ends are three discharge ends.

[0013] Both the first and second transverse channels include oblique channels, with the left end of the oblique channel forming a horizontal straight extension.

[0014] The first channel group and the second channel group both include a second vertical channel. The right ends of the first and second horizontal channels are connected to the middle of the corresponding second vertical channels. The ends of the two second vertical channels that are far apart are connected to one end of the third horizontal channel. The other end of the third horizontal channel is connected to the middle of the third vertical channel. The two ends of the third vertical channel are discharge ends. The other end of the second vertical channel is formed with a horizontally extending through groove, the end of which is a discharge end.

[0015] The center points of all the discharge ends are located on the same vertical axis.

[0016] A front end plate is fixed on the front wall of the main vertical channel plate. A main feed through hole is formed in the middle of the front end plate. The main feed through hole corresponds to and communicates with the feed port at the right end of the main feed channel. A feed pipe connector is welded and fixed in the middle of the front wall of the front end plate. The feed pipe connector communicates with the main feed through hole. The front end plate covers the front wall of the main vertical channel plate.

[0017] A rear fixed end plate is fixed on the rear wall of the main vertical channel plate. The front wall of the rear fixed end plate covers the rear end face of the entire main vertical channel plate. Multiple discharge through holes are formed on the rear fixed end plate, and the discharge through holes are connected to and correspond to the corresponding discharge ends.

[0018] Multiple rear discharge connecting pipe heads are fixed on the rear wall surface of the rear fixed end plate, and the rear discharge connecting pipe heads are connected to and correspond to the corresponding discharge through holes.

[0019] The outstanding effect of this utility model is:

[0020] Compared with existing technologies, it can evenly distribute the material entering the main feed channel to the discharge ends in stages to meet the requirement of a number of discharge ends that are not powers of 2, ensuring that the discharge volume of the material discharged from all discharge ends is basically the same, which greatly improves the diversion effect. Moreover, it is smaller in size, further reducing its space occupation, and making the volume of the heat exchanger with this component greatly reduced. Attached Figure Description

[0031] For example, see below. Figures 2 to 10 As shown, a uniformly distributed flow channel structure includes a main feed channel 1, the outlet of which is connected to the middle of a first vertical channel 2, one end of the first vertical channel 2 is connected to one end of a first transverse channel 3, and the other end of the first vertical channel 2 is connected to one end of a second transverse channel 4.

[0032] The other end of the first transverse channel 3 is connected to the first channel group 100, and the other end of the second transverse channel 4 is connected to the second channel group 200. The final discharge end of the first channel group 100 is an even number, the first transverse channel 3 is a horizontal straight channel, the final discharge end of the second channel group 200 is an odd number except 1, the second transverse channel 4 is an inclined channel, and the total feed channel 1 is an inclined channel.

[0033] When the final discharge end of the first channel group 100 is an even number, it includes a second vertical channel 101. The two ends of the second vertical channel 101 are respectively connected to one end of a third horizontal channel 102. The other ends of the two third horizontal channels 102 are connected to the middle of the corresponding two third vertical channels 103. The two ends of the third vertical channel 103 are discharge ends, or the two ends of the third vertical channel 103 are connected to the corresponding fourth horizontal channel, etc., and so on, forming a 2 to the power of N discharge ends. All its horizontal channels are horizontal straight channels and are set perpendicular to all vertical channels.

[0034] The final discharge end of the second channel group 200 is an odd number other than 1, including the second vertical channel 101. One end of the second vertical channel 101 is connected to one end of the third horizontal channel 102, and the other end of the third horizontal channel 102 is connected to the middle of the third vertical channel 103. Both ends of the third vertical channel 103 are discharge ends, and the other end of the second vertical channel 101 is a discharge end (in order to ensure that the central axis of all discharge ends is on the same vertical line, an extension channel part is formed at the corresponding end of the second vertical channel 101, and the end of the extension channel part is the discharge end). At this time, one end of the second horizontal channel 4 is connected to the middle of the corresponding second vertical channel 101. The second horizontal channel 4 is an oblique channel.

[0035] like Figure 3As shown, the first channel group 100 has two final discharge ends, and the second channel group 200 has three final discharge ends.

[0036] The principle of equal distribution in this embodiment is as follows: Figure 10 As shown:

[0037] A flow rate of q 0， A fluid with velocity u0 is incident on a plane at an angle θ. The mass flow rates q1 and q2 of the two streams should satisfy the following relationship with θ (where the flow rate of q1 is less than that of q2):

[0038] Excluding the influence of other minor factors, it can basically be set as a three-fluid system. Neglecting gravity, we can obtain the following from Bernoulli's equation:

[0039] It can be deduced that ;

[0040] Conservation of momentum in the horizontal direction:

[0041]

[0042] By solving the simultaneous equations, we can obtain:

[0043]

[0044] The above formula is an ideal formula. In specific embodiments, it still has certain deviations due to the influence of channel length, diameter and connection position.

[0045] like Figure 3 As shown, its q 1： When q2 is 2:3, we can obtain 78°. However, during manufacturing, the angle can vary depending on the actual cross-sectional size and length of the channel, as well as deviations in the connection positions between channels. For example, if the connection positions separate the channel into two pipes of different lengths, the angle will also differ. The angle can be adjusted during actual manufacturing; therefore, a specific value can be chosen. The angle between 48° and 108°, as shown in the diagram (a = 48° to 108°), indicates that the angle between the main feed channel 1 of the inclined channel and the first vertical channel 2 is 48° to 108°. Since the first channel group 100 has two final discharge ends, q at the first channel group 100... 1： q2 is 1:1, and the angle between its corresponding first horizontal channel 3 and its corresponding second vertical channel 101 is... 90°, take The angle is 60° to 120°, i.e., c = 60° to 120°. The final discharge end at the second channel group 200 has three outlets. Therefore, q at the second channel group 200...1： q2 is 1:2, so we can get 70°, but during manufacturing, the value is taken as... The angle between 40° and 100°, i.e., b=40° to 100° in the diagram, refers to the angle between the second vertical channel 101 and the second horizontal channel 4, which is an oblique channel, being 40° to 100°. The ±30° deviation is influenced by factors such as the actual connection position and the diameter and length of the channels, which will not be detailed here. In practice, a=78°, b=70°, and c=90° are used. When the values ​​are not 90°, the channels are not perpendicular.

[0046] The above settings ensure that the material entering through the main feed channel 1 can flow out evenly from all the discharge ends, thus ensuring the uniformity of the material flow.

[0047] like Figure 5 As shown, the first channel group 100 has four final discharge ends, and the second channel group 200 has three final discharge ends. Figure 3 The difference is that the first channel group has 4 final discharge ends at point 100, therefore, its q 1： q2 is 3:4, so we can get 82°, but during manufacturing, the value is taken as... The angle is 52° to 112°, which is a = 52° to 112° in the diagram. The final discharge end of the first channel group 100 is 4, which is a power of 2 discharge end. The q at the first channel group 100 is... 1： q2 is 1:1, and the angle c between its corresponding first horizontal channel 3 and the corresponding second vertical channel 101 is 90°. c can be set to 60° to 120°. The final discharge end at the second channel group 200 has three outlets, consistent with the five outlets mentioned above, with b = 40° to 100°. The ±30° deviation is influenced by factors such as the actual connection position and the diameter and length of the channels, which will not be detailed here. In practice, a = 82°, b = 70°, and c = 90° are used. When the values ​​are not 90°, the channels are not perpendicular.

[0048] And such Figure 4As shown, the final discharge ends of the first channel group 200 and the second channel group 200 are both odd numbers other than 1, and they have the same structure. They both include a second vertical channel 101. One end of the second vertical channel 101 is connected to one end of the third horizontal channel 102, and the other end of the third horizontal channel 102 is connected to the middle of the third vertical channel 103. The two ends of the third vertical channel 103 are discharge ends, and the other end of the second vertical channel 101 is a discharge end (in order to ensure that the central axis of all discharge ends is on the same vertical line, an extension channel part is formed at the corresponding end of the second vertical channel 101, and the end of the extension channel part is the discharge end). At this time, one end of the second horizontal channel 4 is connected to the middle of the corresponding second vertical channel 101. The second horizontal channel 4 is an oblique channel.

[0049] The first channel group 100 has three final discharge ends, and the second channel group 200 has three final discharge ends. 1： q2 is 1:1, so we can get 90°, which is a=90° in the diagram, can be taken as a=60° to 120°; and the final discharge ends of the first channel group 100 and the second channel group 200 are 3, therefore, q at the first channel group 100 and the second channel group 200 1： q2 is 1:2, and the angle between its corresponding first horizontal channel 3 and its corresponding second vertical channel 101 is... 70°, that is, c=70° in the diagram, but during manufacturing, the value is taken as... 40° to 100°, i.e., c=40° to 100° in the diagram. Similarly, b=40° to 100° at the second channel group 200.

[0050] Further expansion can be made as needed, which will not be elaborated here. The ±30° deviation is affected by other factors such as the actual connection position and the diameter and length of the channel, which will not be elaborated here. Here, a=90°, b=70°, c=70° are actually taken. When the values ​​are not 90°, the channels are not perpendicular.

[0051] And such Figure 2 As shown, the first channel group 100 has two final discharge ends, the other end of the second transverse channel 4 is a discharge end, and the first transverse channel 3 is a horizontal straight channel. When the first channel group 100 has two final discharge ends, it includes a second vertical channel 101, with both ends of the second vertical channel 101 being discharge ends, and one end of the first transverse channel 3 connecting to the middle of the second vertical channel 101.

[0052] At this time q 1： q2 is 1:2, meaning the angle between the main feed channel 1 and the first vertical channel 2 is 1:2. 70°, where a = 70° in the diagram, but the actual value used during manufacturing is different. The angle is 40° to 100°, as shown in the diagram (a = 40° to 100°). At this point, the second vertical channel 101 is perpendicular to the first horizontal channel 3, i.e., c = 90°. In practice, c can be taken as 60° to 120°. Similarly, the second horizontal channel 4 is perpendicular to the first vertical channel 2, i.e., b = 90°. b can be taken as 60° to 120°. The ±30° deviation is influenced by the actual connection position and the diameter and length of the channels, etc., and will not be detailed here. In practice, a = 70°, b = 90°, and c = 90° are used. When the values ​​are not 90°, the channels are not perpendicular.

[0053] The above settings ensure that the material entering through the main feed channel 1 flows out evenly from all the discharge ends, thus guaranteeing the uniformity of the flowing material. Decimal values ​​in this embodiment are omitted.

[0054] Subsequent equal-division channels such as 1 to 9 and 1 to 11 can be continuously extended and expanded in the same way as described above, which will not be elaborated here.

[0055] A plate-type flow divider with a uniformly divided flow channel structure, manufactured in the above manner, includes a main vertical channel plate 10. A transversely extending main feed channel 1 is formed in the middle of the main vertical channel plate 10. The right end of the main feed channel 1 is the feed inlet.

The other end of the first transverse channel 3 is connected to the first channel group 100, and the other end of the second transverse channel 4 is connected to the second channel group 200.

[0056] The first channel group 100 and the second channel group 200 have the same structure, and their final discharge ends are three discharge ends.

[0057] Both the first transverse channel 3 and the second transverse channel 4 include oblique channels, with the left end of the oblique channel forming a horizontal straight extension.

The other end of the third horizontal channel 102 is connected to the middle of the third vertical channel 103. The two ends of the third vertical channel 103 are discharge ends. The other end of the second vertical channel 101 is formed with a horizontally extending through groove, the end of which is a discharge end.

[0059] The center points of all the discharge ends are located on the same vertical axis.

[0060] A front end plate 20 is welded and fixed to the front wall of the main vertical channel plate 10. A total feed through hole 21 is formed in the middle of the front end plate 20. The total feed through hole 21 corresponds to and communicates with the feed inlet at the right end of the total feed channel 1. A feed pipe connector 22 is welded and fixed to the middle of the front wall of the front end plate 20. The feed pipe connector 22 communicates with the total feed through hole 21. The front end plate 20 covers the front wall of the main vertical channel plate 10.

[0061] A rear fixed end plate 30 is welded and fixed on the rear wall of the main vertical channel plate 10. The front wall of the rear fixed end plate 30 covers the entire rear end face of the main vertical channel plate 10. Multiple discharge through holes 31 are formed on the rear fixed end plate 30.

[0062] Multiple rear discharge connecting pipe heads 32 are welded and fixed on the rear wall surface of the rear fixed end plate 30. The rear discharge connecting pipe heads 32 are connected to and correspond to the corresponding discharge through holes 31.

[0063] It has a structure of one to six. In this embodiment, the main feed channel 1 is divided into six equal parts in the middle, which results in a good distribution effect and ensures that the flow rate and velocity of the material coming out from the discharge end are basically equal.

[0064] Furthermore, according to the embodiment shown in the attached drawings, it is a plate-type connection method with a very small thickness, which makes its space occupation very small, greatly reducing the volume of the heat exchanger it is installed in and reducing space occupation.
