[0040] Example 1
[0041] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a flow channel plate device, including:
[0042] Housing 20, and fin assembly 10 disposed in housing 20;
[0043] The fin assembly 10 includes a fin mechanism 100 and a partition mechanism 200;
[0044] The fin mechanism 100 includes a plurality of fin units 110 arranged in parallel in sequence and a plurality of connecting plates 120; the fin unit 110 includes a first plate 111, a second plate 112 and a third plate 113 connected in sequence; the first plate 111 and the third plate 113 are disposed on both sides of the bottom of the second plate 112 to enclose and form a U-shaped groove flow channel with the opening facing downward; the bottom of the first plate 111 of one fin unit 110 is connected to the bottom of the third plate 113 of another adjacent fin unit 110 through the connecting plate 120 to enclose and form a U-shaped groove flow channel with the opening facing downward;
[0045] The partition mechanism 200 includes at least a top plate 210, a first vertical plate 211, and a first flat plate 212 connected in sequence; the first vertical plate 211 is hermetically disposed between the inlet 21 and the outlet 22 of the shell 20; the top plate 210 and the first flat plate 212 are respectively disposed at both ends of the first vertical plate 211 in the height direction, and the top plate 210 and the first flat plate 212 are opposite to each other; along the width direction of the fin assembly 10, a fin unit 110 located in the middle of the fin mechanism 100 is named the middle fin 101; the top plate 210 and the second plate 112 of the middle fin 101 are arranged coplanarly, the first vertical plate 211 and the first plate 111 or the second plate 112 of the middle fin 101 are arranged coplanarly, and the first flat plate 212 and the connecting plate 120 adjacent to the middle fin 101 are arranged coplanarly.
[0046] The baffle mechanism 200 can separate the inlet 21 and outlet 22 of the housing 20 to form two separate chambers, so that fluid flows out sequentially from the inlet 21, through the fin mechanism 100 and then from the outlet 22.
[0047] In this design, the baffle structure of the flow channel plate device is coplanar with the second plate 112 of the central fin 101, and the first vertical plate 211 is hermetically disposed between the inlet 21 and outlet 22 of the housing 20. This allows the baffle mechanism 200 to separate the inlet 21 and outlet 22 within the housing 20. Simultaneously, the first vertical plate 211 is coplanar with either the first plate 111 or the second plate 112 of the central fin 101, thus ensuring unobstructed flow. Furthermore, the top plate 210 is coplanar with the second plate 112 of the central fin 101, and the first flat plate 212 is coplanar with the adjacent connecting plate 120 of the central fin 101, ensuring smooth flow in the flow channel. This coplanar arrangement of the baffle mechanism 200 with the central fin 101 ensures both separation of the inlet 21 and outlet 22 and unobstructed flow, while also offering advantages such as simple structure and convenient installation.
[0048] Please continue reading. Figure 1 , Figure 2 , Figure 3 To understand more structural details of the flow channel plate device. It should be noted that the central fin 101 is not necessarily the fin unit 110 that is exactly centered along the width direction of the fin mechanism 100, but can also be any fin unit 110 on either side of the centered fin unit 110.
[0049] The first plate 111, the second plate 112, and the third plate 113 of the fin unit 110 shown in the figure are all flat plates, so that the cross-section of the fin unit 110 is rectangular. It is easy to understand that in other descriptions of this utility model, the fin unit 110 can also be wavy, trapezoidal, louvered, etc. Those skilled in the art should be able to make reasonable selections and designs according to actual needs, and no specific limitations are made here.
[0050] It should be noted that the shell 20 includes an upper plate and a lower plate, which together form a sealed inner cavity. The shell 20 has a through-hole inlet 21 and an outlet 22. A fin assembly 10 is disposed within the inner cavity, with its top abutting against the upper plate and its bottom abutting against the lower plate. A partition mechanism 200 is disposed between the inlet 21 and the outlet 22, with a top plate 210 abutting against the upper plate and a first flat plate 212 abutting against the lower plate, so that the partition mechanism 200 can seal the portion of the inner cavity directly opposite the inlet 21 and the outlet 22. Optionally, the top plate 210 is sealed-welded to the bottom of the upper plate, the first flat plate 212 is sealed-welded to the top of the bottom plate, and the first vertical plate 211 seals the portion of the inner cavity directly opposite the inlet 21 and the outlet 22.
[0051] Optionally, the multiple fin units 110 and multiple connecting plates 120 are all integrally formed, which helps to ensure the overall structural stability and reliability. Furthermore, the partition mechanism 200 and the fin mechanism 100 are also integrally formed; that is, the partition structure can be formed by the central fin 101 or the adjacent fin units 110 of the central fin 101, and the extension of the connecting plate 120. In this way, the entire flow channel plate device can be integrally formed using processes such as stamping, thereby improving processing efficiency and ensuring the overall structural stability and reliability of the flow channel plate device.
[0052] It is easy to understand that in other embodiments, the flow channel plate device may be partially integrally formed. For example, the parts of the fin unit 110 may be spliced by welding, or the fin unit 110 and the connecting plate 120 may be spliced by welding, or the partition structure and the fin mechanism 100 may be welded. This is just an example, and the specific setting method is not limited.
[0053] As can be seen from the figure, multiple fin units 110 are arranged in parallel along the width direction of the fin mechanism 100, and adjacent fin units 110 are connected by a connecting plate 120. Along the width direction of the connecting plate 120, one end of the connecting plate 120 is connected to the bottom of the first plate 111 of one fin unit 110, and the other end of the connecting plate 120 is connected to the bottom of the third plate 113 of another adjacent fin unit 110. That is, the fin units 110 form a U-shaped groove structure with the groove opening facing downwards.
[0054] In an optional embodiment, the first plate 111 and the third plate 113 are parallel to each other in the fin unit 110. This makes the structure of the fin unit 110 more stable. It is easy to understand that in other embodiments, the first plate 111 and the third plate 113 may also have an included angle. For example, the first plate 111, the second plate 112, and the third plate 113 may form a trapezoidal shape, etc. This is just an example and is not a limitation.
[0055] In an optional embodiment, in the fin unit 110, both the first plate 111 and the third plate 113 are perpendicular to the second plate 112. This facilitates the installation of the first plate 111 and the third plate 113, thereby ensuring a more stable structure for the fin unit 110. It is easy to understand that in other embodiments, the first plate 111 and the third plate 113 also have acute or obtuse angles with the second plate 112; this is merely an example and not a limitation.
[0056] In an optional implementation, the first plate 111 and the third plate 113 in the fin unit 110 have the same height. This ensures that the height of the entire fin assembly 10 remains consistent. It is easy to understand that in other embodiments, the first plate 111 and the third plate 113 may not be exactly the same; this is merely an example and not a limitation.
[0057] In an optional embodiment, the top plate 210 and the second plate 112, which are coplanar with the middle fin 101, have the same width. It is easy to understand that in other embodiments, the width of the top plate 210 may be greater than or less than the width of the second plate 112; this is merely an example and is not intended to limit the scope.
[0058] In an optional embodiment, the first vertical plate 211 has the same height as the first plate 111 or the third plate 113 that are coplanar with the middle fin 101.
[0059] In an optional embodiment, the width of the first plate 212 is the same as that of the connecting plate 120, which is adjacent to and coplanar with the central fin 101. It is easy to understand that in other embodiments, the width of the first plate 212 may be greater than or less than the width of the connecting plate 120; this is merely an example and is not intended to limit the scope.
[0060] like Figure 1 and Figure 3 As shown, in one embodiment, the partition mechanism 200 includes only a top plate 210, a first vertical plate 211, and a first flat plate 212 connected in sequence. In this case, the longitudinal section of the partition mechanism 200 is a structure formed by bending the plate in an S-shape.
[0061] Furthermore, the top plate 210 of the partition mechanism 200 is disposed on the top of the first vertical plate 211, and the first flat plate 212 is disposed on the bottom of the first vertical plate 211. The first vertical plate 211 maintains an angle with the top plate 210 and the first flat plate 212. The top plate 210 and the first flat plate 212 are respectively located on both sides of the width direction of the first vertical plate 211. Along the width direction of the fin mechanism 100, the partition mechanism 200 is disposed on the fin unit 110 in the middle of the fin mechanism 100. The top plate 210 is coplanar with the second plate 112 of the middle fin 101, the first vertical plate 211 is coplanar with the first plate 111 or the second plate 112, and the first flat plate 212 is coplanar with the connecting plate 120 adjacent to the middle fin 101.
[0062] Secondly, the present invention provides a heater, which includes the flow channel plate device of any of the foregoing embodiments.
[0063] Example 2
[0064] like Figure 4 As shown, this embodiment is largely the same as the previous one, except that the partition mechanism 200 in this embodiment further includes a second vertical plate 221 and a second flat plate 222 connected in sequence. The second vertical plate 221 is arranged opposite to the first vertical plate 211, and the second flat plate 222 is far away from the first flat plate 212.
[0065] The second vertical plate 221 is arranged coplanarly with the third plate 113 or the first plate 111 of the middle fin, and the second flat plate 222 is arranged coplanarly with the connecting plate 120 adjacent to the middle fin. This makes the structure of the partition mechanism 200 more stable. That is, the partition mechanism 200 encloses and forms an upward-facing U-shaped groove structure.
[0066] Furthermore, the second vertical plate 221 is disposed at the end of the top plate 210 away from the first vertical plate 211, so that the second vertical plate 221 is coplanar with the third plate 113 or the first plate 111 of the middle fin 101; the second bottom plate is disposed at the bottom of the second vertical plate 221, so that the second bottom plate is coplanar with the connecting plate 120 adjacent to the middle fin 101. Thus, the first vertical plate 211 and the second vertical plate 221 of the partition mechanism 200 simultaneously serve to separate the inlet 21 and the outlet 22 of the flow channel plate assembly.
[0067] Example 3
[0068] like Figure 5 As shown, this embodiment is largely the same as Embodiment 2, except that in this embodiment, the second vertical plate 221 is arranged coplanarly with the third plate 113 or the first plate 111 of another fin unit 110 adjacent to the middle fin, and the second flat plate 222 is arranged coplanarly with the second plate 112 of the aforementioned fin unit 110. That is, the partition mechanism 200 encloses and forms a U-shaped groove structure with the opening facing downward.
[0069] Furthermore, the second vertical plate 221 is disposed at the end of the first bottom plate away from the first vertical plate 211, so that the second vertical plate 221 is coplanar with the third plate 113 or the first plate 111 of another fin unit 110 adjacent to the central fin 101; the second bottom plate is disposed at the top of the second vertical plate 221, so that the second bottom plate is coplanar with the second plate 112 of another fin unit 110 adjacent to the central fin 101.
[0070] Thus, the first vertical plate 211 and the second vertical plate 221 of the partition mechanism 200 simultaneously serve to separate the inlet 21 and outlet 22 of the flow channel plate assembly.
[0071] Example 4
[0072] like Figure 6 As shown, this embodiment is largely the same as the three embodiments, except that multiple through holes 230 are provided on the first vertical plate 211 or the second vertical plate 221. In this embodiment, multiple through holes 230 are provided on the first vertical plate 211.
[0073] In this way, only the first vertical plate 211 can maintain the inlet 21 and outlet 22 of the separation flow channel plate assembly, while the second vertical plate 221 increases the fluid flow capacity of the U-shaped groove structure.
[0074] In summary, the present invention provides a flow channel plate device and a heater, which have at least the following advantages:
[0075] By extending a section of the fin as a partition, the configuration of the partition mechanism 200 can be simplified, and the overall structural performance is better.
[0076] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
