[0039] 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.

[0040] 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.

[0041] like Figure 1 Figure 2 as well as Figure 5 As shown, in one embodiment, the heater 100 includes a housing 10, an electric heating component 20, and a heat-conducting component 30; the housing 10 is provided with a medium flow channel 3; the electric heating component 20 connects the housing 10 and the heat-conducting component 30; the heat-conducting component 30 is located in the medium flow channel, and one end of the heat-conducting component 30 away from the electric heating component 20 abuts against the housing 10.

[0042] In this application, the electric heating component 20 can generate heat after being energized, thereby heating the medium in the medium flow channel 3. At the same time, the heat-conducting element 30 extends into the medium flow channel and can contact the medium in the medium flow channel 3. Subsequently, the heat generated by the electric heating component 20 can be transferred to the medium in contact with it through the heat-conducting element 30, which can improve the heat transfer effect and thus improve the heating effect on the medium.

[0043] In addition, when the heat-conducting component 30 touches the outer shell 10, its length extending into the medium flow channel 3 is at its maximum. Therefore, the arrangement in this embodiment can also allow the heat-conducting component 30 to extend into the medium flow channel 3 as much as possible, increasing its contact area with the medium, thereby further improving the heating effect on the medium.

[0044] In one embodiment, the heat-conducting element 30 is elastically deformable in the arrangement direction of the outer shell 10 and the heat-conducting element 30. This can compensate for errors during parts processing and assembly, and facilitate the assembly of the heater 100.

[0045] like Figures 5 to 7 As shown, in one embodiment, the heat-conducting component 30 includes a heat-conducting plate 301 and a plurality of heat-conducting fins 302; the heat-conducting plate 301 has a first mounting surface and a second mounting surface arranged opposite to each other; the first mounting surface is connected to the heating assembly 20; the heat-conducting fins 302 are connected to the second mounting surface and abut against the housing 10; the heat-conducting fins 302 are elastically deformable in the arrangement direction of the housing 10 and the heat-conducting component 30.

[0046] The heat-conducting plate 301 is attached to the electric heating element 20, which can improve the heat transfer effect of the electric heating element 20 to the heat-conducting element 30. At the same time, the heat-conducting fins 302 can improve the heat transfer effect between the heat-conducting plate 301 and the medium.

[0047] Furthermore, the heat-conducting fins 302 abut against the housing, thereby ensuring that the end of the heat-conducting component 30 facing away from the heating assembly 20 abuts against the housing. The heat-conducting fins 302 are elastically deformable, thereby enabling the elastic deformation of the heat-conducting component 30.

[0048] In one embodiment, the heat-conducting plate 301 and the heat-conducting fins 302 are an integral structure. This facilitates the production of the heat-conducting component 30 and the assembly of the heater 100.

[0049] like Figure 5 and Figure 6 As shown, in one embodiment, the heat-conducting plate 301 is provided with weight-reducing holes 303; the weight-reducing holes 303 penetrate the heat-conducting plate 301 in the arrangement direction of the first mounting surface and the second mounting surface. This can reduce the weight of the heater 100.

[0050] The heat-conducting component 30 can be formed from a metal plate through processes such as punching and bending. Specifically, the metal plate is first punched to remove a portion of its area to form a weight-reducing hole 303. At this point, the portion of the metal plate retained includes the heat-conducting plate 301 and a protrusion connected to the heat-conducting plate 301 and located within the weight-reducing hole 303. Subsequently, the protrusion is bent to extend beyond the heat-conducting plate 301, forming a heat-conducting fin 302.

[0051] The angle between the heat-conducting fins 302 and the heat-conducting plate 301 can be an acute angle.

[0052] Subsequently, when the heat-conducting fins 302 are pressed in the direction toward the heat-conducting plate 301, the heat-conducting fins 302 can undergo elastic deformation to move closer to the heat-conducting plate 301. At this time, the angle between the heat-conducting fins 302 and the heat-conducting plate 301 can become smaller.

[0053] In one embodiment, there are multiple heat-conducting fins 302, which are spaced apart from each other. "Multiple" means two or more, and the meaning of the term "multiple" is the same in all embodiments, and will not be repeated hereafter.

[0054] like Figure 3 As shown, in one embodiment, the outer casing 10 includes a housing 1 and a partition 2; a medium flow channel 3 is disposed in the housing 1; 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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 3, and their heights are both less than the height of the sidewall of the medium flow channel 3, meaning there is a height difference at their connection points with the sidewall of the medium flow channel 3. 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 3. Similarly, the surface of the second diverter plate 5 facing away from the bottom surface of the medium flow channel 3 can be a plane, and it can be parallel to the bottom surface of the medium flow channel 3.

[0064] 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 3. 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 3. The surface of the baffle 2 facing away from the bottom surface of the medium flow channel 3 can be a plane, and it can be parallel to the bottom surface of the medium flow channel 3.

[0065] The surface on which the opening of the medium flow channel 3 is located (defined as the connecting surface) can be a plane. Furthermore, the bottom surface of the medium flow channel can also be a plane, parallel to the connecting surface.

[0066] In one embodiment, at least one heat-conducting fin 302 abuts against the partition 2; and / or, at least one heat-conducting fin 302 abuts against the first diverter plate 4; and / or, at least one heat-conducting fin 302 abuts against the second diverter plate 5. Of course, in other embodiments, there may be only one or two heat-conducting fins 302 abutting against the partition 2, the first diverter plate 4, and the second diverter plate 5.

[0067] In this context, the heat-conducting fin 302 touching the partition plate 2 can represent the heat-conducting component 30 touching the outer shell, the heat-conducting fin 302 touching the first diversion plate 4 can also represent the heat-conducting component 30 touching the outer shell, and the heat-conducting fin 302 touching the second diversion plate 5 can also represent the heat-conducting component 30 touching the outer shell.

[0068] In addition, when the medium flows in the medium channel 3, its flow velocity is relatively large at the first flow divider 4 and the second flow divider 5. When the medium is in this area, its heating effect is usually poor. Therefore, the heating effect of the medium can be improved by contacting the heat-conducting fins 302 with the first flow divider 4. Similarly, the heating effect of the medium can be improved by contacting the heat-conducting fins 302 with the second flow divider 5.

[0069] In one embodiment, each first diverter plate 4 has at least one heat-conducting fin 302 abutting against it, and similarly, each second diverter plate 5 has at least one heat-conducting fin 302 abutting against it.

[0070] like Figure 3As 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] In one embodiment, the heat-conducting fin 302 abuts against the drainage portion 231, thereby achieving contact between the heat-conducting fin 302 and the partition 2.

[0083] When the medium flows in the medium channel 3, its flow velocity is relatively high at the flow guide. When the medium is in this area, its heating effect is usually poor. Therefore, the heating effect of the medium can be improved by contacting the heat-conducting fins 302 with the flow guide 231.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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 surface 61 of the first guide block 6 located in the third receiving cavity 35 is opposite to the third side wall 13.

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.

This can improve the supporting effect of the housing 1 on the heating element 20 and prevent the heating element 20 from bending and deforming due to its own weight and other factors.

[0112] like Figure 8 and Figure 9 As shown, the electric heating assembly 20 includes an insulating plate 201 and an electric heating unit 202.
