[0036] Please refer to Figures 1-4 The embodiment provides a flow channel plate 100, which comprises a shell 110 and a plurality of guide plates 120.

[0037] The shell 110 is provided with a liquid inlet 111 and a liquid outlet 112 which are communicated with the inside of the shell 110.

[0038] The plurality of guide plates 120 are sequentially arranged in the shell 110 along the direction from the liquid inlet 111 to the liquid outlet 112, and the adjacent guide plates 120 are arranged in staggered manner and form a main flow channel (the main flow channel extension direction is shown by arrow A in Figure 2 and Figure 3 ).

[0039] Please refer to Figures 1-4 The working principle of the flow channel plate 100 is as follows:

[0040] The flow channel plate 100 comprises a shell 110 and a plurality of guide plates 120; wherein the shell 110 is provided with a liquid inlet 111 and a liquid outlet 112 which are communicated with the inside of the shell 110; and the plurality of guide plates 120 are sequentially arranged in the shell 110 along the direction from the liquid inlet 111 to the liquid outlet 112, and the adjacent guide plates 120 are arranged in staggered manner and form a zigzag structure, so that the plurality of guide plates 120 can form a main flow channel which linearly extends from the liquid inlet 111 to the liquid outlet 112 together with the shell 110 through the array arrangement and the zigzag structure, and such flow channel structure can not only simplify the structure and manufacturing cost, but also improve the heating efficiency.

[0041] Further, please refer to Figures 1-4In the embodiment, according to the foregoing, the multiple guide plates 120 are arranged in the shell 110, and the multiple guide plates 120 are arranged in staggered manner, and then the staggered structure is formed in the shell 110 after being assembled in the shell 110, so that the heat exchange efficiency is improved by the staggered structure design, thereby improving the heating efficiency. Therefore, when the guide plates 120 are arranged, each guide plate 120 forms multiple sub-flow channels together with the shell 110 along the extension direction of the guide plate 120, each sub-flow channel extends along the direction from the liquid inlet 111 to the liquid outlet 112, and because the multiple guide plates 120 are arranged in the staggered direction when arranged in the shell 110, that is, the staggered structure is formed, so that each sub-flow channel formed by the adjacent two guide plates 120 is arranged in the partially corresponding conduction manner, thereby making each sub-flow channel correspond to two sub-flow channels formed by the adjacent guide plates 120.

[0042] Because the arrangement direction of the multiple guide plates 120 is consistent with the extension direction of the main flow channel, each sub-flow channel correspond to two sub-flow channels formed by the adjacent guide plates 120 along the extension direction of the main flow channel, thereby enabling the liquid to flow in the main flow channel to converge and diverge in different sub-flow channels during the heating process, thereby improving the heating efficiency.

[0043] In addition, when the guide plates 120 are arranged, each guide plate 120 can form multiple sub-flow channels after being installed in the shell 110, therefore, the guide plates 120 are arranged in the bent manner, specifically, the guide plates 120 are continuously bent to form multiple bent segments 121, the bending directions of the adjacent two bent segments 121 are opposite, and each bent segment 121 corresponds to a sub-flow channel. In addition, when the bent segments 121 are arranged, the multiple sub-flow channels are arranged in sequence, and the staggered arrangement form is formed by the adjacent guide plates 120, therefore, the length of each bent segment 121 is consistent along the extension direction of the guide plate 120. In order to improve the heating efficiency, the bottom of each bent segment 121 is a flat surface that is attached to the inner wall of the shell 110, thereby increasing the contact area with the shell 110 to improve the heat exchange efficiency.

[0044] It should be noted that in the embodiment, the bent segments are rectangular, and in other embodiments of the utility model, the shape of the bent segments can be adjusted according to actual use requirements, for example, the shape of the bent segments can be set as a wave shape, a rectangular shape, a trapezoidal shape, or a louver shape.

[0045] Please refer to Figures 1-4 , and combine Figure 5For the convenience of the plurality of flow channel plates 100 corresponding to the conduction, and the communication with the external liquid inlet pipe 220 and liquid outlet pipe 230, therefore, the liquid inlet 111 and the liquid outlet 112 are both configured with liquid inlet connecting pipe 113 and liquid outlet connecting pipe 114; the liquid inlet connecting pipe 113 is used for communicating with the liquid inlet 111 of the adjacent flow channel plate 100 or the external liquid inlet pipe 220, and the liquid outlet connecting pipe 114 is used for communicating with the liquid outlet 112 of the adjacent flow channel plate 100 or the external liquid outlet pipe 230. Thus, through the above-mentioned liquid inlet connecting pipe 113 and liquid outlet connecting pipe 114, the liquid inlet connecting pipe 113 and liquid outlet connecting pipe 114 of one of the flow channel plates 100 can be communicated with the external liquid inlet pipe 220 and liquid outlet pipe 230, and the adjacent two flow channel plates 100 are communicated, and the liquid inlet connecting pipe 113 and liquid outlet connecting pipe 114 of one of the flow channel plates 100 are communicated with the liquid inlet 111 and liquid outlet 112 of the other flow channel plate 100, respectively.

[0046] In addition, please refer to Figures 1-4 When the plurality of flow channel plates 100 in the foregoing are installed in the shell 110 to form the main flow channel, the plate group structure formed by the plurality of flow channel plates 100 is spaced from the four walls of the inner cavity of the shell 110, that is, the four walls of the shell 110 and the plurality of flow channel plates 100 located in the shell 110 form a flow guide area, so that the edge area of the inner cavity of the flow channel plate 100 can play a role in guiding the flow.

[0047] Based on the above-mentioned flow channel plate 100, please refer to Figures 1-6 The embodiment also provides a heating core 200, which comprises a heating assembly 210, a liquid inlet pipe 220, a liquid outlet pipe 230 and a plurality of the above-mentioned flow channel plates 100.

[0048] The plurality of flow channel plates 100 are sequentially stacked; the heating assembly 210 comprises a plurality of heating plates 211, and at least one heating plate 211 is arranged between any two adjacent flow channel plates 100.

[0049] The liquid inlet pipe 220 and the liquid outlet pipe 230 are connected with one of the flow channel plates 100, and the liquid inlet 111 of each flow channel plate 100 is communicated with the liquid inlet pipe 220, and the liquid outlet 112 of each flow channel plate 100 is communicated with the liquid outlet pipe 230.

[0050] The heating core 200 is made of the flow channel plate 100, and has the advantages of simple structure and high heating efficiency. When the heating plate 211 is arranged, the main flow channel in the flow channel plate 100 is a straight flow channel structure, so the heating plate 211 can be arranged between the liquid inlet end and the liquid outlet end, so that the liquid inlet pipe 220 and the liquid outlet pipe 230 are arranged along the extension direction of the main flow channel, and the heating plate 211 is located between the liquid inlet connecting pipe 113 and the liquid outlet connecting pipe 114.

[0051] Based on the above, Figures 1-6 The embodiment further provides a heater comprising the heating core 200. The heater comprises the heating core 200, and has the advantages of simple structure, low manufacturing cost and high heating efficiency.

[0052] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
