[0034] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 3 As shown, in one embodiment, the heater 10 includes a housing 1 and a partition 2; the housing 1 is provided with a medium flow channel 3; the partition 2 is disposed in the medium flow channel 3 to divide the medium flow channel 3 into a first flow channel 31 and a second flow channel 32 arranged in parallel; the surface of the partition 2 facing the first flow channel 31 is provided with at least one first recess 21, and the sidewall of the medium flow channel 3 is provided with a first diverter plate 4 located in the first flow channel 31, the first diverter plate 4 extending into the first recess 21 and spaced apart from the partition 2.

[0037] The medium flow channel 3 is divided into a first flow channel 31 and a second flow channel 32 arranged in parallel, which can reduce the width of a single flow channel and effectively prevent turbulence in the medium flow channel 3, thereby improving the heating effect of the shell 1 on the medium in the medium flow channel 3.

[0038] In addition, the first recess 21 can increase the residence time of the medium in the first flow channel 31, thereby improving the heating effect of the medium.

[0039] In addition, the sidewall of the medium flow channel 3 of the first diverter plate 4 extends to the first recess 21, which can further increase the residence time of the medium in the first flow channel 31. At the same time, it can also reduce the width of the flow channel in the area where the first recess 21 is located, so as to avoid the medium from generating turbulence in the first recess 21.

[0040] It should be noted that "the extension direction of the medium flow channel 3" refers to the flow direction of the medium within the medium flow channel 3. The "extension direction of the medium flow channel 3" can be a straight line or a curve. The medium can be water, etc.

[0041] like Figure 3 As shown, in one embodiment, the surface of the partition 2 facing the second flow channel 32 is provided with at least one second recess 22, and the sidewall of the medium flow channel 3 is provided with a second diverter 5 located in the second flow channel 32. The second diverter 5 extends into the second recess 22 and is spaced apart from the partition 2.

[0042] The second recess 22 can increase the residence time of the medium in the second flow channel 32, thereby improving the heating effect of the medium.

[0043] In addition, the extension of the sidewall of the medium flow channel 3 of the second diverter plate 5 to the second recess 22 can further increase the residence time of the medium in the second flow channel 32. At the same time, it can also reduce the width of the flow channel in the area where the second recess 22 is located, thus preventing the medium from generating turbulence in the second recess 22.

[0044] like Figure 3 As shown, in one embodiment, the first recess 21 and the second recess 22 are alternately arranged in the extending direction of the medium flow channel 3. In this case, the number of the first recess 21 and the second recess 22 can be the same, or one of them can have one more recess than the other.

[0045] In one embodiment, both the first diverter plate 4 and the second diverter plate 5 are located on the bottom surface of the medium flow channel, and their heights are both less than the height of the sidewall of the medium flow channel, meaning there is a height difference at their connection points with the sidewall of the medium flow channel. The surface of the first diverter plate 4 facing away from the bottom surface of the medium flow channel can be a plane, and it can be parallel to the bottom surface of the medium flow channel. Similarly, the surface of the second diverter plate 5 facing away from the bottom surface of the medium flow channel can be a plane, and it can be parallel to the bottom surface of the medium flow channel.

[0046] Additionally, the baffle 2 is also located on the bottom surface of the medium flow channel, and its height can be less than the height of the side wall of the medium flow channel. Of course, in some scenarios, the height of the baffle 2 can also be equal to or greater than the height of the side wall of the medium flow channel. The surface of the baffle 2 facing away from the bottom surface of the medium flow channel can be a plane, and it can be parallel to the bottom surface of the medium flow channel.

[0047] The surface on which the opening of the medium flow channel is located (defined as the connection surface) can be a plane. Furthermore, the bottom surface of the medium flow channel can also be a plane, parallel to the connection surface.

[0048] like Figure 3 As shown, in one embodiment, the partition 2 includes a curved structure 23, which includes a drainage portion 231, a first connecting portion 232, and a second connecting portion 233. The number of drainage portions 231 is plurality of them. In the extending direction of the medium flow channel 3, the drainage portions 231 are arranged at intervals, and the first connecting portion 232 and the second connecting portion 233 are alternately arranged. The two ends of the first connecting portion 232 are connected to the ends of adjacent drainage portions 231 to form a first recess 21. The two ends of the second connecting portion 233 are connected to the ends of adjacent drainage portions 231 to form a second recess 22. This embodiment facilitates the processing of the first recess 21 and the second recess 22. "Number of" means two or more, and the meaning of "number of" is the same in all embodiments, and will not be repeated hereafter.

[0049] Furthermore, two adjacent drainage portions 231 are located on the same side of the first connecting portion 232 that connects them, and two adjacent drainage portions 231 are located on the same side of the second connecting portion 233 that connects them. In addition, the drainage portion 231 that connects both the first connecting portion 232 and the second connecting portion 233 is located between the first connecting portion 232 and the second connecting portion 233 to which it is connected.

[0050] In one embodiment, the drainage portion 231 has a linear structure, for example, it can be a cuboid structure. In addition, each drainage portion 231 can be arranged in parallel, and the spacing between adjacent drainage portions 231 can be equal.

[0051] In one embodiment, the first connecting portion 232 has an arc-shaped structure, and the concave part of the arc-shaped structure faces the space between the two drain portions 231 connected to it.

[0052] In one embodiment, the second connecting portion 233 has an arc-shaped structure, and the concave part of the arc-shaped structure faces the space between the two drain portions 231 connected to it.

[0053] In other embodiments, the drainage portion 231 may also be a non-linear structure, such as an arc-shaped structure. In other embodiments, both the first connecting portion 232 and the second connecting portion 233 may be linear structures, such as cuboid structures.

[0054] In addition, when both the first connecting part 232 and the second connecting part 233 are arc-shaped structures, a first connecting part 232, a second connecting part 233 and the drainage part 231 connecting the two can form an S-shaped structure.

[0055] It should be understood that the first diverter plate 4 and the second diverter plate 5 are both located between two adjacent drainage sections 231.

[0056] In one embodiment, the first diverter plate 4 can be a linear structure, for example, it can be a cuboid structure. Moreover, the first diverter plate 4 can be parallel to the drainage section 231.

[0057] In one embodiment, when there are multiple first recesses 21, there can also be multiple first diverter plates 4, and the first recesses 21 and the first diverter plates 4 correspond one-to-one, with one first diverter plate 4 extending into the corresponding first recess 21.

[0058] In one embodiment, when there are multiple second recesses 22, there can also be multiple second diverter plates 5, and the second recesses 22 and the second diverter plates 5 correspond one-to-one, with one second diverter plate 5 extending into its corresponding second recess 22.

[0059] In other embodiments, a first recess 21 may also contain a plurality of first diverter plates 4, and a second recess 22 may also contain a plurality of second diverter plates 5.

[0060] like Figure 3 As shown, in one embodiment, the housing 1 further has a first guide block 6 located in the first flow channel 31. The first guide block 6 is located at the angle between the first diversion plate 4 and the side wall of the medium flow channel 3, and is spaced apart from the first diversion plate 4, the side wall of the medium flow channel 3, and the partition plate 2. The housing 1 further has a second guide block 7 located in the second flow channel 32. The second guide block 7 is located at the angle between the second diversion plate 5 and the side wall of the medium flow channel 3, and is spaced apart from the second diversion plate 5, the side wall of the medium flow channel 3, and the partition plate 2.

[0061] Normally, there is a large space at the angle between the first diverter plate 4 and the side wall of the medium flow channel 3 (i.e., the intersection of the two), which makes it easy for the medium to generate turbulence in the space. By setting the first guide block 6, the medium can be diverted at this point to reduce the size of the channel used for the medium flow channel 3, thereby avoiding turbulence.

[0062] Similarly, the angle between the second diverter plate 5 and the sidewall of the medium flow channel 3 (i.e., the intersection of the two) has a large space, which makes it easy for the medium to generate turbulence in the space. By setting the second guide block 7, the medium can be diverted at this point to reduce the size of the channel used for the medium flow channel 3, thereby avoiding turbulence.

[0063] In addition, the outer surface of the first guide block 6 can be tilted according to the flow direction of the medium to reduce the obstruction to the flow of the medium.

[0064] like Figure 3 As shown, in one embodiment, the first guide block 6 is a trapezoidal block, having a first surface 61 and a second surface 62, a third surface 63 and a fourth surface 64, and a fifth surface 65 and a sixth surface arranged opposite to each other. The first surface 61 intersects with the third surface 63, the fourth surface 64, the fifth surface 65, and the sixth surface; the second surface 62 intersects with the third surface 63, the fourth surface 64, the fifth surface 65, and the sixth surface; the third surface 63 also intersects with the fifth surface 65 and the sixth surface; and the fourth surface 64 also intersects with the fifth surface 65 and the sixth surface. The first surface 61, the second surface 62, the third surface 63, the fourth surface 64, the fifth surface 65, and the sixth surface constitute the six planes of the trapezoidal block. Additionally, in actual products, the corners of the trapezoidal block may also have chamfered structures.

[0065] Additionally, the first surface 61 faces the sidewall of the medium flow channel 3 (which is used to enclose and form the first flow channel 31), the second surface 62 faces the first diverter plate 4, the third surface 63 faces the angle between the sidewall of the medium flow channel 3 and the first diverter plate 4, the fourth surface 64 faces the partition plate 2, the fifth surface 65 faces the opening of the medium flow channel 3, and the sixth surface is connected to the bottom surface of the medium flow channel 3.

[0066] The first surface 61 may be parallel to a portion of the inner surface of the sidewall of the medium flow channel 3 (this portion is opposite to the first surface 61 and is used to enclose and form the first flow channel 31), and the second surface 62 may be parallel to the surface of the first diverter plate 4 near the first guide block 6.

[0067] Furthermore, the angle between the first surface 61 and the third surface 63 is obtuse, the angle between the first surface 61 and the fourth surface 64 is acute, the angle between the second surface 62 and the third surface 63 is obtuse, and the angle between the second surface 62 and the fourth surface 64 is acute. The third surface 63 is the top surface of the trapezoidal block, and the fourth surface 64 is the bottom surface of the trapezoidal block. Additionally, the fifth surface 65 and the sixth surface can be parallel and both can be perpendicular to the first surface 61, the second surface 62, the third surface 63, and the fourth surface 64.

[0068] In actual products, first guide blocks 6 can be installed at all the angles between the first diverter plate 4 and the medium flow channel 3, or only at some of the angles between the first diverter plate 4 and the medium flow channel 3. In addition, the height of the first guide block 6 is less than the height of the side wall of the medium flow channel 3, that is, the distance between the fifth surface and the sixth surface is less than the distance between the connecting surface and the bottom surface of the medium flow channel.

[0069] In one embodiment, the outer surface of the second guide block 7 may be tilted according to the flow direction of the medium to reduce obstruction to the flow of the medium.

[0070] like Figure 3 As shown, in one embodiment, the second guide block 7 is a trapezoidal block, having a first end face 71 and a second end face 72, a third end face 73 and a fourth end face 74, and a fifth end face 75 and a sixth end face, all arranged opposite to each other. The first end face 71 intersects with the third end face 73, the fourth end face 74, the fifth end face 75, and the sixth end face; the second end face 72 intersects with the third end face 73, the fourth end face 74, the fifth end face 75, and the sixth end face; the third end face 73 also intersects with the fifth end face 75 and the sixth end face; and the fourth end face 74 also intersects with the fifth end face 75 and the sixth end face. The first end face 71, the second end face 72, the third end face 73, the fourth end face 74, the fifth end face 75, and the sixth end face constitute the six planes of the trapezoidal block. Additionally, in actual products, the corners of the trapezoidal block may also have chamfered edges.

[0071] Additionally, the first end face 71 faces the side wall of the medium flow channel 3 (which is used to enclose and form the second flow channel 32), the second end face 72 faces the second diverter plate 5, the third end face 73 faces the angle between the side wall of the medium flow channel 3 and the second diverter plate 5, the fourth end face 74 faces the partition plate 2, the fifth end face 75 faces the opening of the medium flow channel 3, and the sixth end face is connected to the bottom surface of the medium flow channel 3.

[0072] The first end face 71 may be parallel to a portion of the inner surface of the sidewall of the medium flow channel 3 (this portion is opposite to the first end face 71 and is used to enclose and form the second flow channel 32), and the second end face 72 may be parallel to the surface of the second diverter plate 5 near the second guide block 7.

[0073] Furthermore, the angle between the first end face 71 and the third end face 73 is obtuse, the angle between the first end face 71 and the fourth end face 74 is acute, the angle between the second end face 72 and the third end face 73 is obtuse, and the angle between the second end face 72 and the fourth end face 74 is acute. The third end face 73 is the top surface of the trapezoidal block, and the fourth end face 74 is the bottom surface of the trapezoidal block. Additionally, the fifth end face 75 and the sixth end face can be parallel, and both can be perpendicular to the first end face 71, the second end face 72, the third end face 73, and the fourth end face 74.

[0074] In actual products, second guide blocks 7 can be installed at all the angles between the second diverter plate 5 and the medium flow channel 3, or only at some of the angles between the second diverter plate 5 and the medium flow channel 3. In addition, the height of the second guide block 7 is less than the height of the side wall of the medium flow channel 3, that is, the distance between the fifth end face and the sixth end face is less than the distance between the connecting surface and the bottom surface of the medium flow channel.

[0075] like Figure 3 As shown, in one embodiment, in the extending direction of the medium flow channel 3, the medium flow channel 3 includes a first receiving cavity 33, a second receiving cavity 34, and a third receiving cavity 35 that are sequentially connected; the first receiving cavity 33 and the third receiving cavity 35 are located on the same side of the second receiving cavity 34. In this case, the medium flow channel 3 has a U-shaped structure, which can increase the residence time of the medium in the medium flow channel 3, thereby improving the heating effect on the medium.

[0076] like Figure 3As shown, the partition 2 includes a first plate 24, a second plate 25, and a third plate 26 connected in sequence; the first plate 24 is located in the first receiving cavity 33 to divide the first receiving cavity 33 into a first cavity 331 and a second cavity 332; the second plate 25 is located in the second receiving cavity 34 to divide the second receiving cavity 34 into a third cavity 341 and a fourth cavity 342; the third plate 26 is located in the third receiving cavity 35 to divide the third receiving cavity 35 into a fifth cavity 351 and a sixth cavity 352; the first cavity 331, the third cavity 341, and the fifth cavity 351 are connected to form a first flow channel 31; the second cavity 332, the fourth cavity 342, and the sixth cavity 352 are connected to form a second flow channel 32.

[0077] Both the first plate 24 and the third plate 26 can be curved structures 23, and both have a first recess 21 and a second recess 22. Simultaneously, both the first receiving cavity 33 and the third receiving cavity 35 can be provided with a first diverter plate 4, a second diverter plate 5, a first guide block 6, and a second guide block 7. The second plate 25 can be a straight plate, mainly used to connect the first plate 24 and the second plate 25.

[0078] like Figure 3 As shown, in one embodiment, the sidewalls of the medium flow channel 3 include a first sidewall 11, a second sidewall 12, a third sidewall 13, a fourth sidewall 14, and a fifth sidewall 15; the first sidewall 11, the second sidewall 12, and the third sidewall 13 are arranged sequentially at intervals; the two ends of the first sidewall 11 are respectively connected to the fourth sidewall 14 and the fifth sidewall 15; the second sidewall 12 is connected to the fourth sidewall 14 and is spaced apart from the fifth sidewall 15; the two ends of the third sidewall 13 are respectively connected to the fourth sidewall 14 and the fifth sidewall 15; the first receiving cavity 33 is located between the first sidewall 11 and the second sidewall 12, the second receiving cavity 34 is located between the second sidewall 12 and the fifth sidewall 15, and the third receiving cavity 35 is located between the second sidewall 12 and the third sidewall 13.

[0081] like Figure 1 and Figure 3 As shown, in one embodiment, an input hole 16 is also provided on the outer surface of the housing 1, extending to the medium flow channel 3; an output hole 17 is also provided on the outer surface of the housing 1, extending to the medium flow channel 3. During operation, external medium can be input into the medium flow channel 3 through the input hole 16, and at the same time, the medium in the medium flow channel 3 can flow out of the medium flow channel 3 through the output hole 17.

[0082] In one embodiment, the input port 16 forms a first opening 161 on the inner surface of the medium flow channel 3, and the partition 2 is spaced apart from and opposite to the first opening 161; the output port 17 forms a second opening 171 on the inner surface of the medium flow channel 3, and the partition 2 is spaced apart from and opposite to the second opening 171. The inner surface of the medium flow channel 3 is the surface in the housing 1 used to enclose and form the medium flow channel 3.

[0083] That is, the medium flow channel 3 also includes a first connecting cavity 36 and a second connecting cavity 37. The first connecting cavity 36 connects the end of the first flow channel 31 near the input hole 16 and the end of the second flow channel 32 near the input hole 16. The second connecting cavity 37 connects the end of the first flow channel 31 near the output hole 17 and the end of the second flow channel 32 near the output hole 17. During operation, after the medium enters the input hole 16, it flows into the medium channel from the first opening 161. It first enters the first connecting cavity 36, and then flows from the first connecting cavity 36 to the first flow channel 31 and the second flow channel 32. Subsequently, when the medium flows from the medium flow channel 3 to the output hole 17, the medium in the first flow channel 31 and the second flow channel 32 first gathers in the second connecting cavity 37, and then the medium in the second connecting cavity 37 flows into the output hole 17 from the second opening 171.

[0084] In one embodiment, the housing 1, the partition 2, and the first diversion plate 4 are integrally formed, which facilitates production.

The heating plate 8 can generate heat when energized to heat the medium in the medium flow channel 3. This can improve the support effect of the housing 1 on the heating plate 8 and prevent the heating plate 8 from bending and deforming due to its own weight and other factors.

[0087] The heating plate can be connected to the connecting surface and form an opening on the surface that seals the medium flow channel.

[0088] The heating plate includes an insulating plate and a heating element. The insulating plate is connected to the housing and seals the opening formed by the medium flow channel on the connecting surface. The heating element is connected to the insulating plate and located on the side of the insulating plate opposite to the medium flow channel. The heating element is capable of generating heat when energized.

[0089] like Figure 2 As shown, the housing 1 is provided with an installation groove, and the medium flow channel is set on the bottom surface of the installation groove; the heater 10 also includes a first cover plate 91, which is connected to the housing 1 and closes the opening of the installation groove; the heating plate 8 is located between the medium flow channel 3 and the first cover plate 91.

[0090] The first cover plate 91 and the shell 1 enclose a complete chamber, which is divided into two parts by the heating plate. The part between the medium flow channel 3 and the heating plate is the medium receiving chamber, and the medium flow channel 3 is a part of this chamber. Alternatively, the medium flow channel 3 can be sealed by the heating plate to form the chamber. The part between the first cover plate 91 and the heating plate is the heating chamber.

[0091] like Figure 4 As shown, in one embodiment, the housing 1 is further provided with a mounting cavity 18, and the mounting cavity 18 and the medium flow channel 3 are respectively located on opposite sides of the housing 1; the heater 10 also includes a second cover plate 92 (see reference). Figure 2 The second cover plate 92 is connected to the housing 1 and closes the opening of the mounting cavity 18.

[0092] The mounting cavity 18 can be used for corresponding electrical components, such as circuit boards, which can be electrically connected to the heating plate 8, and the operation of the heating plate 8 can be controlled through the circuit board.

[0093] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0094] In other embodiments, the first flow channel 31 may also be located inside the second flow channel 32, that is, compared with the above embodiments, the positions of the first flow channel 31 and the second flow channel 32 are interchanged.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
