Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger-related equipment, and more specifically to a power-two equal distribution structure and a plate distributor 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. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a power-two equal distribution structure and a plate-type distributor using this structure. It divides the material entering the main feed channel into equal parts step by step, ensuring that the amount of material discharged from all discharge ends is basically the same, thus greatly improving the diversion effect.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A 2 to the power of N equal-division structure includes a main feed channel, the outlet of which is connected to the middle of a first vertical channel. Both ends of the first vertical channel are connected to one end of a corresponding first horizontal channel. The other end of the first horizontal channel is connected to the middle of a corresponding second vertical channel. Both ends of the second vertical channel are connected to one end of a corresponding second horizontal channel. The other end of the second horizontal channel is connected to the middle of a corresponding third vertical channel. The two ends of the third vertical channel are the discharge ends. The main feed channel is thus divided into a corresponding number of discharge ends in a 2 to the power of N equal-division manner.

[0007] All vertically extending channels, such as the first vertical channel and the second vertical channel, are parallel to each other. All horizontally extending channels, such as the main feed channel and the first horizontal channel, are parallel to each other. All horizontally extending channels are perpendicular to all vertically extending channels.

[0008] A plate-type distributor with a power of two equal-division 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 a feed inlet, and the left end of the main feed channel connects 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 two first transverse channels formed on the main vertical channel plate. The right end of the first transverse channel connects to the middle of a corresponding second vertical channel formed on the main vertical channel plate. The upper and lower ends of the second vertical channel connect to the right ends of the corresponding second transverse channels formed on the main vertical channel plate. The left end of the second transverse channel connects to the middle of a corresponding third vertical channel formed on the main vertical channel plate. The two ends of the third vertical channel have discharge ends.

[0009] A front fixing plate is welded and fixed to the front wall of the main vertical channel plate. The front fixing plate covers the front wall of the main vertical channel plate. A feed inlet is formed in the middle of the front fixing plate, and the feed inlet is connected to the feed port of the main feed channel.

[0010] A feed inlet is welded and fixed to the front wall of the middle part of the front fixing plate, and the feed inlet is connected to the feed through hole.

[0011] The main vertical channel plate has a vertical return channel formed in the middle, and the front fixed plate has a return hole formed, which communicates with the vertical return channel.

[0012] A return flow connection port is welded and fixed on the front wall of the front fixing plate, and the return flow connection port communicates with the return flow hole.

[0013] The outstanding effect of this utility model is:

[0014] Compared with existing technologies, it distributes the material entering the main feed channel in stages in a power of two manner, ensuring that the amount of 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 size of the heat exchanger with this component much smaller. Attached Figure Description

[0022] For example, see below. Figures 2 to 6 As shown, a power-of-two (POW) equal-division structure includes a main feed channel 1. The outlet of the main feed channel 1 is connected to the middle of a first vertical channel 2. Both ends of the first vertical channel 2 are connected to one end of a corresponding first horizontal channel 3. The other end of the first horizontal channel 3 is connected to the middle of a corresponding second vertical channel 4. Both ends of the second vertical channel 4 are connected to one end of a corresponding second horizontal channel 5. The other end of the second horizontal channel 5 is connected to the middle of a corresponding third vertical channel 6. The two ends of the third vertical channel 6 are the outlet ends. The main feed channel 1 is thus divided into a corresponding number of outlet ends in a power-of-two manner. That is, it can be divided step by step as needed, such as... Figure 2As shown, it is divided into 8 discharge ends by a main feed channel 1. At this time, the two ends of the third vertical channel 6 are discharge ends, i.e., 2 to the power of 3. If 2 to the power of 4 is divided into 16 discharge ends by a main feed channel 1, then the two ends of the last vertical channel 6 are discharge ends, i.e., 2 to the power of 2. If 2 to the power of 4 is divided into 4 discharge ends by a main feed channel 1, then the two ends of the last vertical channel 6 are discharge ends. In this way, it can be divided into equal discharge ends as needed to achieve a basically uniform discharge (due to gravity and some errors in manufacturing, there will be very small deviations, which are negligible).

[0023] Its principle of equal division is as follows: Figure 7 As shown:

[0024] 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:

[0025] 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:

[0026] It can be deduced that ;

[0027] Conservation of momentum in the horizontal direction:

[0028]

[0029] By solving the simultaneous equations, we can obtain:

[0030]

[0031] When q 1： When q2 is 1:1, we can obtain A 90° angle means that all horizontal and vertical channels are perpendicular to each other. At the same time, one end of the horizontal channel is connected to the middle of the corresponding vertical channel, which ensures the uniformity of the material flow.

[0032] All vertically extending channels, such as the first vertical channel 2 and the second vertical channel 4, are parallel to each other. All horizontally extending channels, such as the main feed channel 1 and the first horizontal channel 3, are parallel to each other. All horizontally extending channels are perpendicular to all vertically extending channels.

[0033] It ensures uniform material flow by vertically distributing the flow in the middle, with the center lines of all discharge ends on the same vertical line.

[0034] However, in actual manufacturing, the actual connection location and channel diameter and length, among other factors, can influence the final value. 60° to 120°.

[0035] A plate-type distributor employing the above-described power of two equal-division structure 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, with the right end of the main feed channel 1 serving as a feed inlet. The left end of the main feed channel 1 connects to the middle of a first vertical channel 2, which is formed in the middle of the main vertical channel plate 10. The upper and lower ends of the first vertical channel 2 connect to the left ends of two first transverse channels 3 formed on the main vertical channel plate 10, respectively. The right end of the first transverse channel 3 connects to the middle of a corresponding second vertical channel 4 formed on the main vertical channel plate 10. The upper and lower ends of the second vertical channel 4 connect to the right ends of a corresponding second transverse channel 5 formed on the main vertical channel plate 10. The left end of the second transverse channel 5 connects to the middle of a corresponding third vertical channel 6 formed on the main vertical channel plate 10. The two ends of the third vertical channel 6 have discharge ends.

[0036] Furthermore, a front fixing plate 20 is welded and fixed to the front wall of the main vertical channel plate 10. The front fixing plate 20 covers the front wall of the main vertical channel plate 10. A feed through hole 21 is formed in the middle of the front fixing plate 20. The feed through hole 21 communicates with and corresponds to the feed inlet of the main feed channel 1.

[0037] Furthermore, a feed inlet 22 is welded and fixed to the front wall of the middle part of the front fixing plate 20, and the feed inlet 22 communicates with the feed through hole 21.

[0038] Furthermore, a vertical return channel 12 is formed in the middle of the main vertical channel plate 10, and a return hole 23 is formed on the front fixing plate 20. The return hole 23 communicates with and corresponds to the vertical return channel 12.

[0039] Furthermore, a return flow connection port 24 is welded and fixed on the front wall surface of the front fixing plate 20, and the return flow connection port 24 communicates with the return flow hole 23.

[0040] Furthermore, a rear vertical connecting plate 30 is welded and fixed to the rear wall of the main vertical channel plate 10. The rear vertical connecting plate 30 covers the rear wall of the main vertical channel plate 10. A main return flow groove 31 and a plurality of vertically arranged feed holes 32 are formed on the rear vertical connecting plate 30. The feed holes 32 correspond to and communicate with the corresponding discharge ends.

[0041] Furthermore, a rear thickened connecting plate 40 is welded and fixed to the rear wall of the rear vertical connecting plate 30. The rear thickened connecting plate 40 covers the rear wall of the rear vertical connecting plate 30. A second main return flow groove 41 and a plurality of second sub-feed through holes 42 arranged vertically are formed on the rear thickened connecting plate 40. The second sub-feed through holes 42 are connected to and correspond to the corresponding sub-feed through holes 32. The second main return flow groove 41 is aligned with and connected to the corresponding main return flow groove 31.

[0042] A rear pipeline connecting plate 50 is welded and fixed to the rear wall of the rear thickened connecting plate 40. The rear pipeline connecting plate 50 covers the rear wall of the rear thickened connecting plate 40. Multiple forward-extending connecting pipe sleeves 51 are formed on the rear pipeline connecting plate 50. All connecting pipe sleeves 51 are arranged vertically in two rows. All connecting pipe sleeves 51 in one row are inserted into the second main return flow groove 41, and all connecting pipe sleeves 51 in the other row are inserted into the corresponding second feed through hole 42.

[0043] During manufacturing, one end of the heat exchange circulation pipe is connected to the corresponding connecting pipe sleeve 51, which serves as a flow divider for the heat exchanger. The gas-liquid mixed refrigerant enters from the feed inlet 22 and then into the main feed channel 1. It then flows sequentially through the first vertical channel 2, the first horizontal channel 3, the second vertical channel 4, the second horizontal channel 5, and the third vertical channel 6, and finally flows out from the outlet end of all the third vertical channels 6. In this embodiment, it is a 2 to the power of 3 evenly divided structure. Then, the material at the outlet end flows through the heat exchange circulation pipe to the circulation component (such as a U-shaped connecting pipe) installed at the other end, and flows back to the vertical return circulation channel 12 through the connecting pipe connected to the other end of the circulation component (the vertical return circulation channel 12 is connected to the return end of all the connecting pipes). Finally, it flows out from the return connecting pipe port 24, realizing circulation.

[0044] In this embodiment, the central feeding channel 1 is divided into equal parts in stages, resulting in good distribution and ensuring that the material flow rate and velocity from the discharge end are basically equal.

[0045] 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.

[0046] In this embodiment, the structure integrates the feeding and discharging sections. However, in use and manufacturing, it can also consist only of the feeding section; for example, the vertical return flow channel 12 can be omitted. (See attached diagram.) Figures 2 to 6 In this case, simply remove half of the parts with vertical return grooves 12 and their corresponding portions from all the components.

[0047] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
