[0040] Embodiment 1

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 , this embodiment provides a flow channel plate device, including:

[0042] A housing 20, and a fin assembly 10 disposed in the 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 and a plurality of connecting plates 120 which are sequentially arranged in parallel; the fin unit 110 includes a first plate 111, a second plate 112 and a third plate 113 which are sequentially connected; the first plate 111 and the third plate 113 are arranged on both sides of the bottom of the second plate 112 to enclose a U-shaped groove flow channel with an 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 a U-shaped groove flow channel with an opening facing downward;

[0045] The partition mechanism 200 at least includes 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 arranged between the inlet 21 and the outlet 22 of the shell 20; the top plate 210 and the first flat plate 212 are respectively arranged at both ends of the height direction of the first vertical plate 211, and the top plate 210 and the first flat plate 212 are separated from 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 as the middle fin 101; the top plate 210 is coplanarly arranged with the second plate 112 of the middle fin 101, the first vertical plate 211 is coplanarly arranged with the first plate 111 or the second plate 112 of the middle fin 101, and the first flat plate 212 is coplanarly arranged with the connecting plate 120 adjacent to the middle fin 101;

[0046] The partition mechanism 200 can separate the inlet 21 and the outlet 22 of the shell 20 from each other to form two chambers separated from each other, so that the fluid flows out from the inlet 21, the fin mechanism 100 and then the outlet 22 in sequence.

[0047] The partition structure of the flow channel plate device of the present solution is coplanar with the second plate 112 of the middle fin 101, and the first vertical plate 211 is sealed between the inlet 21 and the outlet 22 of the shell 20, so that the partition mechanism 200 can separate the inlet 21 and the outlet 22 in the shell 20 from each other; at the same time, the first vertical plate 211 is coplanar with the first plate 111 or the second plate 112 of the middle fin 101, so as not to affect the smooth flow of the flow channel. Furthermore, the top plate 210 is coplanar with the second plate 112 of the middle fin 101, and the first flat plate 212 is coplanar with the connecting plate 120 adjacent to the middle fin 101, thus ensuring the smooth flow direction of the flow channel. In this way, the partition mechanism 200 is coplanarly arranged with the middle fin 101, which not only ensures the separation of the inlet 21 and the outlet 22, but also ensures the smooth flow of the flow channel, and has the advantages of simple structure and convenient setting.

[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 middle fin 101 is not necessarily the fin unit 110 exactly centered along the width direction of the fin mechanism 100, and can also be located at any fin unit 110 on both sides 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 straight plates, so that the cross section of the fin unit 110 is rectangular. It is not difficult to understand that in other descriptions of the present invention, the fin unit 110 can also be wavy, trapezoidal, louvered, etc., and those skilled in the art should be able to make reasonable selections and designs according to actual needs, and no specific restrictions are made here.

[0050] It should be noted that the shell 20 includes an upper plate and a lower plate, which enclose a closed inner cavity; the shell 20 is provided with an inlet 21 and an outlet 22 that penetrate through; the fin assembly 10 is arranged in the inner cavity, and the top of the fin assembly 10 abuts against the upper plate, and the bottom of the fin assembly 10 abuts against the lower plate; the partition mechanism 200 is arranged between the inlet 21 and the outlet 22, and the top plate 210 abuts against the upper plate, and the first flat plate 212 abuts against the lower plate, so that the partition mechanism 200 can hermetically separate the part of the inner cavity that is directly opposite to the inlet 21 and the outlet 22. Optionally, the top plate 210 is hermetically welded to the bottom of the upper plate, the first flat plate 212 is hermetically welded to the top of the bottom plate, and the first vertical plate 211 hermetically separates the part of the inner cavity that is directly opposite to the inlet 21 and the outlet 22.

[0051] Optionally, the plurality of fin units 110 and the plurality of connecting plates 120 are integrally formed, which is conducive to ensuring the stability and reliability of the overall structure. Furthermore, the partition mechanism 200 and the fin mechanism 100 are also integrally formed, that is, the partition structure can be formed by extending the middle fin 101 or the fin unit 110 adjacent to the middle fin 101, and the connecting plate 120. In this way, the entire flow channel plate device can be integrally formed using a process that is conducive to stamping, etc., which is conducive to improving processing efficiency and ensuring the stability and reliability of the overall structure of the flow channel plate device.

[0052] It is not difficult to understand that in other embodiments, the flow channel plate device may only be partially integrated. For example, the parts of the fin unit 110 may be spliced ​​by welding or the like, or the fin unit 110 and the connecting plate 120 may be spliced ​​by welding or the like, or the partition structure and the fin mechanism 100 may be welded or the like. This is just an example and the specific setting method is not limited.

[0053] It can also be seen from the figure that along the width direction of the fin mechanism 100, a plurality of fin units 110 are arranged in parallel in sequence, 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 unit 110 forms a U-shaped groove structure with the notch facing downward.

[0054] In an optional embodiment, in the fin unit 110, the first plate 111 and the third plate 113 are parallel to each other. This makes the structure of the fin unit 110 more stable. It is not difficult to understand that in other embodiments, the first plate 111 and the third plate 113 may also have an angle. For example, the first plate 111, the second plate 112 and the third plate 113 may form a trapezoid or the like. This is just an example and is not limiting.

[0055] In an optional embodiment, in the fin unit 110, the first plate 111 and the third plate 113 are both perpendicular to the second plate 112. This facilitates the installation of the first plate 111 and the third plate 113, thereby ensuring that the structure of the fin unit 110 is more stable. It is not difficult to understand that in other embodiments, the first plate 111 and the third plate 113 also have an acute angle or an obtuse angle with the second plate 112, which is only an example and is not limited thereto.

[0056] In an optional embodiment, in the fin unit 110, the first plate 111 and the third plate 113 have the same height. In this way, the height of the entire fin assembly 10 remains consistent. It is not difficult to understand that in other embodiments, the first plate 111 and the third plate 113 may also be not completely the same, which is only an example and is not limiting.

[0057] In an optional embodiment, the width of the top plate 210 is the same as that of the coplanar second plate 112 of the middle fin 101. It is not difficult to understand that in other embodiments, the width of the top plate 210 can also be greater than or less than the width of the second plate 112, which is only an example and not limiting.

[0058] In an optional embodiment, the first vertical plate 211 has the same height as the coplanar first plate 111 or the third plate 113 of the middle fin 101 .

[0059] In an optional embodiment, the first flat plate 212 has the same width as the adjacent and coplanar connecting plate 120 of the middle fin 101. It is easy to understand that in other embodiments, the width of the first flat plate 212 can also be greater than or less than the width of the connecting plate 120, which is only an example and not limiting.

[0060] like Figure 1 and Figure 3 As shown, in one embodiment, the partition mechanism 200 only includes a top plate 210, a first vertical plate 211 and a first flat plate 212 connected in sequence. At this time, the longitudinal section of the partition mechanism 200 is a structure formed by bending the plate into an S shape.

[0061] Furthermore, the top plate 210 of the partition mechanism 200 is arranged on the top of the first vertical plate 211, and the first flat plate 212 is arranged 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; and 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 arranged on the fin unit 110 in the middle of the fin mechanism 100, and the top plate 210 is arranged coplanar with the second plate 112 of the middle fin 101, the first vertical plate 211 is arranged coplanar with the first plate 111 or the second plate 112, and the first flat plate 212 is arranged coplanar with the connecting plate 120 adjacent to the middle fin 101.

[0062] In a second aspect, the present invention provides a heater, the heater comprising the flow channel plate device of any one of the aforementioned embodiments.

[0063] Embodiment 2

[0064] like Figure 4 As shown, this embodiment is substantially the same as the embodiment, except that the partition mechanism 200 of 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 a U-shaped groove structure with an opening facing upward.

[0066] Furthermore, the second vertical plate 221 is disposed at one end of the top plate 210 away from the first vertical plate 211, so that the second vertical plate 221 is arranged coplanarly 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 arranged coplanarly with the connecting plate 120 adjacent to the middle fin 101. In this way, the first vertical plate 211 and the second vertical plate 221 of the partition mechanism 200 simultaneously play the role of separating the inlet 21 and the outlet 22 of the flow channel plate assembly.

[0067] Embodiment 3

[0068] like Figure 5As shown, this embodiment is substantially the same as the second embodiment, except that the second vertical plate 221 of this embodiment is coplanarly arranged 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 coplanarly arranged with the second plate 112 of the above 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 arranged at one end of the first bottom plate away from the first vertical plate 211, so that the second vertical plate 221 is arranged coplanar with the third plate 113 or the first plate 111 of another fin unit 110 adjacent to the middle fin 101; the second bottom plate is arranged on 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 middle fin 101.

[0070] In this way, the first vertical plate 211 and the second vertical plate 221 of the partition mechanism 200 simultaneously play the role of separating the inlet 21 and the outlet 22 of the flow channel plate assembly.

[0071] Embodiment 4

[0072] like Figure 6 As shown, this embodiment is substantially the same as the third embodiment, except that a plurality of through holes 230 are provided on the first vertical plate 211 or the second vertical plate 221. In this embodiment, a plurality of through holes 230 are provided on the first vertical plate 211.

[0073] In this way, only the first vertical plate 211 can maintain the separation of the inlet 21 and the outlet 22 of the flow channel plate assembly, while the second vertical plate 221 increases the flow capacity of the fluid in the U-shaped groove structure.

[0074] In summary, the embodiments of the present invention provide a flow channel plate device and a heater, which have at least the following advantages:

[0075] By extending a section of the fin to serve as a partition, the arrangement of the partition mechanism 200 can be simplified, and the overall structural performance is better.

[0076] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
