[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0031] like Figures 1 to 2 As shown, in one embodiment, a flow channel 1 is provided on the heater 100. The flow channel 1 penetrates the heater 100 in a first direction. During use, external fluid can enter the heater 100 through the flow channel 1 and can flow out of the heater 100 through the flow channel 1. In addition, the heater 100 includes a support member 2, a first heating member 3, and a second heating member 4. The first heating member 3 and the second heating member 4 are spaced apart along the second direction on the support member 2 and enclose the support member 2 to form the flow channel 1. The first heating member 3 and the second heating member 4 are both used to heat the fluid in the flow channel 1.
[0032] In the prior art, the heating element of a heater can only heat the fluid in the flow channel 1 from one side. In contrast, in this embodiment, the first heating element 3 and the second heating element 4 can heat the fluid in the flow channel 1 from both sides of the flow channel 1, thereby improving the heating effect on the fluid in the flow channel 1. This can increase the heating power without increasing the size of the heater 100, thereby reducing the cost of the heater 100 and facilitating the installation and use of the heater 100.
[0033] It should be noted that both the first heating element 3 and the second heating element 4 can generate heat by being powered on. When in use, the first heating element 3 and the second heating element 4 are both connected to a power source so that the first heating element 3 and the second heating element 4 are powered by the power source. In this way, the first heating element 3 and the second heating element 4 can generate heat, thereby heating the fluid in the flow channel 1.
[0034] The flow channel 1 is a through-hole structure, and the fluid outside the heater 100 can flow into the flow channel 1 and can flow out of the heater 100 from the flow channel 1. When working, the flow channel 1 of the heater 100 can be connected in series in a corresponding fluid circuit.
[0035] In addition, when working, in a first direction, the heater 100 has a first side and a second side arranged opposite to each other, and the fluid flows into the heater 100 (i.e., into the flow channel 1) from the first side of the heater 100 and flows out of the flow channel 1 from the second side of the heater 100.
[0036] In one embodiment, the first direction and the second direction may be perpendicular to each other. Figure 1Of the directions shown, the first direction may be parallel to the Z axis, and the second direction may be parallel to the X axis.
[0037] Furthermore, the fluid may be a liquid such as water or a gas such as air.
[0038] like Figure 1 As shown, in one embodiment, at least a portion of the flow channel 1 is a curved structure, which can increase the area of the side wall of the flow channel 1 used to contact the fluid and increase the residence time of the fluid in the flow channel 1, thereby improving the heating effect on the fluid in the flow channel 1.
[0039] The side wall of the flow channel 1 includes at least a portion of the support member 2 , at least a portion of the first heating member 3 , and at least a portion of the second support member 2 .
[0040] In addition, the curved structure may be an arc-shaped curved structure, which can reduce the obstruction of the side wall of the flow channel 1 to the fluid.
[0041] In one embodiment, the flow channel 1 has a wavy structure, which can further increase the area of the sidewall of the flow channel 1 that is in contact with the fluid and increase the residence time of the fluid in the flow channel 1. The wavy shape of the flow channel 1 extends along the length of the flow channel 1, and the length of the flow channel 1 can be referred to as the first direction.
[0042] like Figures 1 to 2 As shown, in one embodiment, a first concave structure 31 is provided on a surface of the first heating element 3 close to the second heating element 4 (this surface is defined as the first surface), and a first convex structure 41 is provided on a surface of the second heating element 4 close to the first heating element 3 (this surface is defined as the second surface); in the second direction, the first concave structure 31 and the first convex structure 41 overlap.
[0043] In the second direction, the overlapping area of the first concave structure 31 and the first convex structure 41 forms a curved structure of the flow channel 1 .
[0044] In addition, in the second direction, the overlap of the first concave structure 31 and the first convex structure 41 may mean that: in an orthographic projection of a plane (defined as the first plane) perpendicular to the second direction, the projection of the first concave structure 31 and the projection of the first convex structure 41 at least partially overlap.
[0045] Preferably, in the orthographic projection of the first plane, the projection of the first concave structure 31 and the projection of the first convex structure completely overlap, that is, the projection of the first concave structure 31 is entirely located within the projection of the first convex structure 41, and the projection of the first convex structure 41 is entirely located within the projection of the first concave structure 31.
[0046] In one embodiment, the first concave structure 31 is a circular arc groove, and the first convex structure 41 is a circular arc protrusion. The inner diameters of the arc groove and the arc protrusion can be the same. In this case, the axis of the first concave structure 31 is parallel to the third direction. In this case, the axis of the arc structure of the first convex structure 41 is also parallel to the third direction. Furthermore, in an orthographic projection onto a plane perpendicular to the third direction, the line connecting the projections of the axes of the first concave structure 31 and the first convex structure 41 is parallel to the second direction.
[0047] In addition, in the third direction, the first concave structure 31 extends from one end surface of the first heating element 3 to the other end surface of the first heating element 3, and the first convex structure 41 extends from one end surface of the second heating element 4 to the other end surface of the second heating element 4. The first direction, the second direction and the third direction intersect with each other.
[0048] Preferably, the first direction, the second direction and the third direction are perpendicular to each other. Figure 1 , the third direction is parallel to the Y axis.
[0049] In addition, the first surface and the second surface may be arranged in parallel.
[0050] like Figures 1 to 2 As shown, in one embodiment, a second protruding structure 32 is provided on the surface of the first heating element 3 near the second heating element 4, and a second concave structure 42 is provided on the surface of the second heating element 4 near the first heating element 3. In the second direction, the second concave structure 42 and the second protruding structure 32 overlap. In addition, in the first direction, the first concave structure 31 and the second protruding structure 32 are spaced apart, and the second concave structure 42 and the first protruding structure 41 are spaced apart. This further increases the area of the sidewall of the flow channel 1 that is exposed to the fluid.
[0051] In the second direction, the overlapping area of the second concave structure 42 and the second convex structure 32 forms a curved structure of the flow channel 1 .
[0052] In addition, in the second direction, the second concave structure 42 and the second convex structure 32 overlap each other, which may mean that, in the orthographic projection of the first plane, the projection of the second concave structure 42 and the projection of the second convex structure 32 at least partially overlap.
[0053] Preferably, in the orthographic projection of the first plane, the projection of the second concave structure 42 and the projection of the second convex structure completely overlap, that is, the projection of the second concave structure 42 is entirely located within the projection of the second convex structure 32, and the projection of the second convex structure 32 is entirely located within the projection of the second concave structure 42.
[0054] In one embodiment, the second concave structure 42 is a circular arc groove, and the second protrusion 32 is a circular arc protrusion. The inner diameters of the arc groove and the arc protrusion can be the same. In this case, the axis of the second concave structure 42 is parallel to the third direction. In this case, the axis of the arc structure of the second protrusion 32 is also parallel to the third direction. Furthermore, in an orthographic projection onto a plane perpendicular to the third direction, the line connecting the projection of the axis of the second concave structure 42 and the projection of the axis of the second protrusion 32 is parallel to the second direction.
[0055] In addition, in the third direction, the second concave structure 42 extends from one end surface of the second heating element 4 to the other end surface of the second heating element 4 , and the second convex structure 32 extends from one end surface of the first heating element 3 to the other end surface of the first heating element 3 .
[0056] In one embodiment, the first surface is wavy, the second surface is also wavy, and the first surface is parallel to the second surface.
[0057] In one embodiment, the first concave structures 31 correspond to the first convex structures 41 one to one, and in the X-axis direction, each first concave structure 31 overlaps with its corresponding first convex structure 41 .
[0058] In addition, the number of the first concave structures 31 and the number of the first convex structures 41 can be multiple, and the first concave structures 31 are arranged at intervals along the Z-axis direction, and the first convex structures 41 are arranged at intervals along the Z-axis direction.
[0059] In one embodiment, the second concave structures 42 correspond to the second convex structures 32 in a one-to-one manner. In the X-axis direction, each second concave structure 42 overlaps with its corresponding second convex structure 32 .
[0060] In addition, the number of the second concave structures 42 and the second convex structures 32 can be multiple, and the second concave structures 42 are arranged at intervals along the Z-axis direction, and the second convex structures 32 are arranged at intervals along the Z-axis direction.
[0061] In one embodiment, when the first heating element 3 includes both a first concave structure 31 and a second convex structure 32, at least one of the first concave structure 31 and the second convex structure 32 is provided in multiple numbers, and the first concave structures 31 and the second convex structures 32 are alternately arranged in the Z-axis direction. In this case, the second heating element 4 includes both a first convex structure 41 and a second concave structure 42, and the number of the first concave structures 31 is equal to the number of the first convex structures 41, and the number of the second concave structures 42 is equal to the number of the second convex structures 32. In this manner, the first convex structures 41 and the second concave structures 42 are alternately arranged in the Z-axis direction. This allows the flow channel 1 to form a wavy structure.
[0062] like Figures 1 to 2As shown, in one embodiment, the first heating element 3 includes a first heating film 33 and a first heat conducting plate 34 ; the first heat conducting plate 34 is connected to the support member 2 , and the first heating film 33 is arranged on the surface of the first heat conducting plate 34 facing away from the second heating element 4 .
[0063] The flow channel 1 formed by the first heating element 3, the second heating element 4, and the support member 2 actually refers to the first heat conducting plate 34, the second heating element 4, and the support member 2 forming the flow channel 1. The first heating film 33 is connected to a power source so that power is supplied to the first heating film 33. When powered, the first heating film 33 generates heat, and the first heat conducting plate 34 transfers the heat generated by the first heating film 33 to the fluid in the flow channel 1.
[0064] In addition, the first heating film 33 is arranged on the surface of the first heat conducting plate 34 facing away from the second heating element 4, which means that the first heating film 33 is located outside the flow channel 1. This can prevent the first heating film 33 from contacting the fluid in the flow channel 1, thereby improving the safety of the heater 100.
[0065] In one embodiment, the first heating film 33 is a graphene coating. This configuration facilitates the acquisition of materials for the first heating film 33 and reduces the manufacturing process temperature, thereby reducing the material cost and manufacturing difficulty of the heater 100. Of course, in other embodiments, the first heating film 33 may also be a silver-palladium resistor film or a nickel-chromium resistor film.
[0066] In one embodiment, the first heating film 33 may completely cover the surface of the first heat conducting plate 34 facing away from the second heating element 4 , or the first heating film 33 may only cover a portion of the surface of the first heat conducting plate 34 facing away from the second heating element 4 .
[0067] like Figures 1 to 2 As shown, in one embodiment, the first heat conducting plate 34 includes a first plate body 341 and a first heat dissipating fin 342; the first plate body 341 is connected to the support member 2, the first heating film 33 is arranged on the surface of the first plate body 341 away from the second heating member 4, and the first heat dissipating fin 342 is arranged on the surface of the first plate body 341 close to the second heating member 4.
[0068] The first heat conducting plate 34 , the second heating element 4 and the supporting element 2 enclose the flow channel 1 , which actually means that the first plate 341 , the second heating element 4 and the supporting element 2 enclose the flow channel 1 .
[0069] The first heat dissipation fins 342 are arranged in the flow channel 1, which can increase the contact area between the first heat conducting plate 34 and the fluid in the flow channel 1, thereby improving the heat exchange effect between the first heat conducting plate 34 and the fluid, thereby improving the heating effect of the fluid in the flow channel 1.
[0070] In addition, the first surface is the surface of the first plate 341 close to the second heating element 4 .
[0071] In one embodiment, the material of the first plate 341 may be stainless steel or aluminum alloy, and the material of the first heat dissipating fins 342 may also be stainless steel or aluminum alloy.
[0072] In one embodiment, at least a portion of the first plate 341 is curved, for example, the first plate 341 may be wavy. In this case, at least a portion of the surface of the first plate 341 facing away from the second heating element 4 is curved. This increases the area of the first plate 341 supporting the first heating film 33, thereby increasing the coverage area of the first heating film 33 and improving the heating effect on the fluid.
[0073] In one embodiment, the thickness of each region of the first plate 341 may be uniform, where the thickness of the first plate 341 refers to the size of a region thereof in the X-axis direction. Furthermore, the thickness of each region of the first heating film 33 may be uniform, where the thickness of the first heating film 33 refers to the size of a region thereof in the X-axis direction.
[0074] In one embodiment, along the third direction, the first heat dissipating fins 342 extend from one end surface of the first plate body 341 to the other end surface of the first plate body 341 .
[0075] In addition, there may be a plurality of first heat dissipation fins 342 , and the first heat dissipation fins 342 are sequentially spaced apart along the first direction.
[0076] In one embodiment, the first plate 341 and the first heat dissipating fins 342 may be an integrally formed structure; or, the first plate 341 and the first heat dissipating fins 342 may be split structures and assembled together by bonding, bolts, or other connecting members.
[0077] like Figure 1 As shown, in one embodiment, the second heating element 4 includes a second heating film 43 and a second heat conducting plate 44 ; the second heat conducting plate 44 is connected to the support member 2 , and the second heating film 43 is arranged on the surface of the second heat conducting plate 44 facing away from the first heating element 3 .
[0078] The flow channel 1 formed by the first heating element 3, the second heating element 4, and the support member 2 actually refers to the second heat conducting plate 44, the first heating element 3 (specifically, the first plate 341), and the support member 2. The second heating film 43 is connected to a power source so that power is supplied to the second heating film 43. When energized, the second heating film 43 generates heat, and the second heat conducting plate 44 transfers the heat generated by the second heating film 43 to the fluid in the flow channel 1.
[0079] In addition, the second heating film 43 is arranged on the surface of the second heat conducting plate 44 facing away from the first heating element 3, which means that the second heating film 43 is located outside the flow channel 1. This can prevent the second heating film 43 from contacting the fluid in the flow channel 1, thereby improving the safety of the heater 100.
[0080] In one embodiment, the second heating film 43 is a graphene coating. This configuration makes it easier to obtain the material for the second heating film 43 and reduces the manufacturing process temperature, thereby reducing the material cost and manufacturing difficulty of the heater 100. Of course, in other embodiments, the second heating film 43 can also be a silver-palladium resistor film or a nickel-chromium resistor film.
[0081] In one embodiment, the second heating film 43 may completely cover the surface of the second heat conducting plate 44 facing away from the second heating element 4 , or the second heating film 43 may only cover a portion of the surface of the second heat conducting plate 44 facing away from the second heating element 4 .
[0082] like Figure 1 As shown, in one embodiment, the second heat conduction plate 44 includes a second plate body 441 and a second heat dissipation fin 442; the second plate body 441 is connected to the support member 2, the second heating film 43 is arranged on the surface of the second plate body 441 away from the first heating member 3, and the second heat dissipation fin 442 is arranged on the surface of the second plate body 441 close to the first heating member 3.
[0083] The second heat conducting plate 44 , the first heating element 3 and the support element 2 enclose the flow channel 1 , which actually means that the first plate 341 , the second plate 441 and the support element 2 enclose the flow channel 1 .
[0084] The second heat dissipation fins 442 are arranged in the flow channel 1, which can increase the contact area between the second heat conducting plate 44 and the fluid in the flow channel 1, thereby improving the heat exchange effect between the second heat conducting plate 44 and the fluid, thereby improving the heating effect of the fluid in the flow channel 1.
[0085] In addition, the second surface is the surface of the second plate 441 close to the first heating element 3 .
[0086] In one embodiment, the second plate 441 may be made of stainless steel or aluminum alloy, and the second heat dissipating fins 442 may also be made of stainless steel or aluminum alloy.
[0087] In one embodiment, at least a portion of the second plate 441 is curved, for example, the second plate 441 may be wavy. In this case, at least a portion of the surface of the second plate 441 facing away from the first heating element 3 is curved. This increases the area of the second plate 441 supporting the second heating film 43, thereby increasing the coverage area of the second heating film 43 and improving the heating effect on the fluid.
[0088] In one embodiment, the thickness of each region of the second plate 441 may be uniform, where the thickness of the second plate 441 refers to the size of a region thereof in the X-axis direction. Furthermore, the thickness of each region of the second heating film 43 may be uniform, where the thickness of the second heating film 43 refers to the size of a region thereof in the X-axis direction.
[0089] In one embodiment, along the third direction, the second heat dissipating fins 442 extend from one end surface of the first plate body 341 to the other end surface of the first plate body 341 .
[0090] In addition, there may be a plurality of second heat dissipation fins 442 , and the second heat dissipation fins 442 are sequentially spaced apart along the first direction.
[0091] In one embodiment, the second plate 441 and the second heat dissipating fins 442 may be an integrally formed structure; or, the second plate 441 and the second heat dissipating fins 442 may be split structures and assembled together by bonding, bolts, or other connecting members.
[0092] In one embodiment, the first heating element 3 and the second heating element 4 may adopt the same structural arrangement, which can reduce the production cost and preparation difficulty of the heater 100 .
[0093] like Figure 1 As shown, in one embodiment, a receiving hole 21 is provided on the support member 2. The receiving hole 21 extends through the support member 2 in a first direction, allowing fluid to pass through the support member 2 from the receiving hole 21. Both the first heating member 3 and the second heating member 4 are disposed within the receiving hole 21. The flow channel 1 is a portion of the receiving hole 21. After assembly, the wall of the receiving hole 21, the first heating member 3, and the second heating member 4 enclose the flow channel 1.
[0094] After assembly, in the third direction, both ends of the first heating element 3 are connected to the support member 2 , and both ends of the second heating element 4 are connected to the support member 2 . Moreover, the first heating element 3 and the second heating element 4 can be sealed and connected to the support member 2 .
[0095] In one embodiment, the support member 2 is further provided with a corresponding avoidance hole so that the corresponding power cord electrically connecting the first heating element 3 and the second heating element 4 can extend from the support member 2 through the receiving hole 21, wherein the power cord can be connected to a power source, and subsequently, the power source supplies power to the first heating element 3 and the second heating element 4 through the power cord. In addition, the method of connecting the power source to the first heating element 3 and the second heating element 4 to power both can be a conventional method.
[0096] like Figure 1As shown, in one embodiment, in the first direction, the receiving hole 21 includes a first section hole 211, a second section hole 212, and a third section hole 213, which are sequentially connected. A first step surface 22 is formed between the first section hole 211 and the second section hole 212, and a second step surface 23 is formed between the second section hole 212 and the third section hole 213. After assembly, the first heating element 3 and the second heating element 4 are both disposed within the second section hole 212, and in the first direction, the two ends of the first heating element 3 are connected to the first step surface 22 and the second step surface 23, respectively. The two ends of the second heating element 4 are connected to the first step surface 22 and the second step surface 23, respectively.
[0097] Specifically, the diameter of the first section hole 211 is smaller than that of the second section hole 212 , so as to form a first step surface 22 therebetween; the diameter of the third section hole 213 is smaller than that of the second section hole 212 , so as to form a second step surface 23 therebetween.
[0098] like Figure 1 As shown, in one embodiment, in the first direction, the support member 2 includes a first section structure 24, a second section structure 25 and a third section structure 26 arranged in sequence, wherein the diameter of the first section structure 24 is smaller than the diameter of the second section structure 25 so as to form a third step surface between the two; the diameter of the third section structure 26 is smaller than the diameter of the second section structure 25 so as to form a fourth step surface between the two.
[0099] In addition, the first section holes 211 are provided on the first section structure 24 , the second section holes 212 are provided on the second section structure 25 , and the third section holes 213 are provided on the third section structure 26 .
[0100] In one embodiment, the flow channel 1 includes the first section of holes 211 , the third section of holes 213 , and the portion of the second section of holes 212 located between the first heating element 3 and the second heating element 4 .
[0101] The support member 2 includes a first plate, a second plate, a third plate, a fourth plate, a fifth plate, and a sixth plate. The first plate and the second plate are spaced apart along the X-axis, the third plate and the fourth plate are spaced apart along the Y-axis, and the fifth plate and the sixth plate are spaced apart along the Z-axis. The first plate is connected to the third plate, the fourth plate, the fifth plate, and the sixth plate, respectively; the second plate is connected to the third plate, the fourth plate, the fifth plate, and the sixth plate, respectively; the third plate is connected to the fifth plate and the sixth plate, respectively; and the fourth plate is connected to the fifth plate and the sixth plate, respectively. The first plate, the second plate, the third plate, the fourth plate, the fifth plate, and the sixth plate enclose a second hole 212.
[0102] The first heating element 3 is connected to the third plate, the fourth plate, the fifth plate and the sixth plate respectively, and the second heating element 4 is connected to the third plate, the fourth plate, the fifth plate and the sixth plate respectively. The first plate, the first heating element 3, the second heating element 4 and the second plate are arranged in sequence in the X-axis direction.
[0103] In addition, support member 2 includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the fifth plate and is located on the side of the fifth plate facing away from the sixth plate. The second connecting portion is connected to the sixth plate and is located on the side of the sixth plate facing away from the fifth plate. A first hole 211 extends from the surface of the first connecting portion facing away from the fifth plate to the surface of the fifth plate facing away from the first connecting portion. A second hole 212 extends from the surface of the second connecting portion facing away from the sixth plate to the surface of the sixth plate facing away from the second connecting portion.
[0104] like Figure 1 As shown, in one embodiment, the heater 100 further includes a first guide plate 5 and a second guide plate 6; the first guide plate 5 and the second guide plate 6 are both arranged in the flow channel 1 and are spaced apart along the first direction; a first flow hole 51 is provided on the first guide plate 5, and a second flow hole 61 is provided on the second guide plate 6; in the first direction, the first flow hole 51 passes through the first guide plate 5, and the second flow hole 61 passes through the second guide plate 6, and the first flow hole 51 and the second flow hole 61 are staggered.
[0105] When the fluid flows in the flow channel 1, it passes through the first guide plate 5 at the first flow hole 51 and passes through the second guide plate 6 at the second flow hole 61. Because the first flow hole 51 and the second flow hole 61 are staggered, the flow direction of the fluid can be adjusted by disposing the first guide plate 5 and the second guide plate 6. This arrangement can increase the residence time of the fluid in the flow channel 1, thereby improving the heating effect of the heating element on the fluid in the flow channel 1. When the fluid flows in the flow channel 1, it can first pass through the first guide plate 5 at the first flow hole 51 and then pass through the second guide plate 6 at the second flow hole 61; alternatively, when the fluid flows in the flow channel 1, it can first pass through the second guide plate 6 at the second flow hole 61 and then pass through the first guide plate 5 at the first flow hole 51.
[0106] In addition, “in the first direction, the first flow hole 51 and the second flow hole 61 are staggered” means that in the first direction, the first flow hole 51 and the second flow hole 61 are staggered.
[0107] Definition: the opening formed by the first flow hole 51 on the surface of the first guide plate 5 close to the second guide plate 6 is the first opening, and the opening formed by the second flow hole 61 on the surface of the second guide plate 6 close to the first guide plate 5 is the second opening.
[0108] In the first direction, the staggered arrangement of the first flow hole 51 and the second flow hole 61 can be regarded as: in the orthographic projection on a plane perpendicular to the first direction (defined as the second plane), the orthographic projection of the first opening and the orthographic projection of the second opening have no overlapping area, or the orthographic projection of the first opening and the orthographic projection of the second opening have an overlapping area, but a part of the orthographic projection of the first opening does not overlap with the orthographic projection of the second opening, and a part of the orthographic projection of the second opening does not overlap with the orthographic projection of the first opening.
[0109] In one embodiment, the material of the first guide plate 5 can be stainless steel or aluminum alloy, and the material of the second guide plate 6 can also be stainless steel or aluminum alloy.
[0110] like Figure 1 As shown, in one embodiment, the first guide plate 5 is arranged between the first concave structure 31 and the first convex structure 41; the second guide plate 6 is arranged between the second concave structure 42 and the second convex structure 32; in the second direction, the first flow hole 51 is located on the side of the second flow hole 61 away from the second concave structure 42.
[0111] In addition, after assembly, each first guide plate 5 is spaced apart from the first step surface 22 and the second step surface 23 , and each second guide plate 6 is spaced apart from the first step surface 22 and the second step surface 23 .
[0112] like Figures 1 to 2 As shown, in one embodiment, the two ends of the first guide plate 5 are respectively connected to the first heat dissipation fin 342 and the second heat dissipation fin 442, and the two ends of the second guide plate 6 are respectively connected to the first heat dissipation fin 342 and the second heat dissipation fin 442. In this way, the heat of the two heat dissipation fins can be transferred to the two guide plates. At this time, the fluid in the flow channel 1 can also be heated through the first guide plate 5 and the second guide plate 6.
[0113] like Figures 1 to 2 As shown, the first heat dissipation fin 342 is provided with a first latch 343 on the surface close to the second heating element 4, and the second heat dissipation fin 442 is provided with a second latch 443 on the surface close to the first heating element 3. The two ends of the first guide plate 5 are respectively disposed in the first opening and the second opening. Similarly, the two ends of the second guide plate 6 are respectively disposed in the first opening and the second opening.
[0114] In one embodiment, along the Y-axis direction, the first latch 343 penetrates from one end surface of the first heat dissipation fin 342 to the other end surface of the first heat dissipation fin 342 , and the second latch 443 penetrates from one end surface of the second heat dissipation fin 442 to the other end surface of the second heat dissipation fin 442 .
[0115] Furthermore, the first guide plate 5 is hermetically connected to the first and second heat dissipating fins 342 and 442, while the second guide plate 6 is hermetically connected to the first and second heat dissipating fins 342 and 442. Furthermore, along the Y-axis, both ends of the first guide plate 5 are hermetically connected to the support member 2, while both ends of the second guide plate 6 are hermetically connected to the support member 2. After assembly, fluid flowing within the flow channel 1 can only pass through the first guide plate 5 at the first flow hole 51 and can only pass through the second guide plate 6 at the second flow hole 61.
[0116] In one embodiment, in the Z-axis direction, the flow holes on the guide plate closest to the first step surface 22 are staggered with the first section holes 211 , and the flow holes on the guide plate closest to the second step surface 23 are staggered with the second section holes 212 .
[0117] exist Figure 1 In the illustrated example, the guide plate closest to the first stepped surface 22 in the Z-axis direction is the first guide plate 5 (defined as guide plate A). In this case, the first hole segment 211 is staggered with the first flow hole 51 on the first guide plate 5 (defined as flow hole A). The staggered arrangement of the first hole segment 211 and flow hole A can mean that, in the orthographic projection of the first plane, the projection of the opening formed by flow hole A on the surface of guide plate A near the first stepped surface 22 (defined as the third opening) does not overlap with the opening formed by the first hole segment 211 on the first stepped surface 22 (defined as the fourth opening). Alternatively, the orthographic projections of the third opening and the fourth opening overlap, but a portion of the orthographic projection of the third opening does not overlap with the orthographic projection of the fourth opening, and a portion of the orthographic projection of the fourth opening does not overlap with the orthographic projection of the third opening.
[0118] exist Figure 1 In the illustrated example, in the Z-axis direction, the guide plate closest to the second stepped surface 23 is the second guide plate 6 (defined as guide plate B). In this case, the second hole segment 212 is staggered with the second flow hole 61 on the second guide plate 6 (defined as flow hole B). The staggered arrangement of the second hole segment 212 and flow hole B can mean that, in the orthographic projection of the first plane, the projection of the opening formed by flow hole B on the surface of guide plate B near the second stepped surface 23 (defined as the fifth opening) does not overlap with the opening formed by the second hole segment 212 on the second stepped surface 23 (defined as the sixth opening). Alternatively, the orthographic projection of the fifth opening and the orthographic projection of the sixth opening overlap, but a portion of the orthographic projection of the fifth opening does not overlap with the orthographic projection of the sixth opening, and a portion of the orthographic projection of the sixth opening does not overlap with the orthographic projection of the fifth opening.
[0119] After assembly, the gap between the guide plate A and the first step surface 22, the gap between the guide plate B and the second step surface 23, and the gap between the adjacent first guide plates 5 and the second guide plates 6 can all be regarded as accommodating cavities, and in the X-axis direction, each accommodating cavity is located between the first heating element 3 and the second heating element 4, and a accommodating cavity can be divided into a first chamber and a second chamber that are connected, and the first chamber is located between the second chamber and the second heating element 4.
[0120] like Figure 1 As shown, in one embodiment, the heater 100 further includes a first temperature sensor 7 , which is disposed on the first heating element 3 and is used to detect the temperature of the first heating element 3 . This allows the temperature of the fluid in the flow channel 1 to be detected.
[0121] Specifically, the first temperature sensor 7 may be connected to the first plate 341 and located on a side of the first plate 341 away from the second heating element 4 .
[0122] In addition, in one embodiment, the external fluid enters the flow channel 1 through the first hole 211 and exits the flow channel 1 through the second hole 212. To improve the accuracy of temperature detection of the fluid in the flow channel 1, the first temperature sensor 7 can be disposed near the second hole 212. For example, the first temperature sensor 7 can be disposed on the second step surface 23.
[0123] In addition, a corresponding avoidance hole is provided on the support member 2 so that the signal line of the first temperature sensor 7 can pass through the support member 2 .
[0124] like Figure 1 As shown, in one embodiment, the heater 100 further includes a second temperature sensor 8, which is disposed on the second heating element 4 and is used to detect the temperature of the second heating element 4. This allows the temperature of the fluid in the flow channel 1 to be detected.
[0125] Specifically, the second temperature sensor 8 may be connected to the second plate 441 and located on a side of the second plate 441 facing away from the second heating element 4 .
[0126] In addition, in order to improve the temperature detection accuracy of the fluid in the flow channel 1 , the second temperature sensor 8 may be disposed close to the second hole 212 . For example, the second temperature sensor 8 may be disposed on the second step surface 23 .
[0127] In addition, a corresponding avoidance hole is provided on the support member 2 so that the signal line of the second temperature sensor 8 can pass through the support member 2 .
[0128] The present invention also provides a vehicle, which includes the heater 100 described in any one of the above embodiments. The heater 100 can be used to heat the air-conditioning system of the vehicle. Specifically, the air-conditioning system has a fluid circuit, and the support member 2 of the heater 100 is connected to the corresponding pipe of the fluid circuit, so that the flow channel 1 is connected in series with the fluid circuit. When working, the water pump of the fluid circuit is started, which can make the fluid flow in the corresponding pipe of the fluid circuit and make the fluid enter the flow channel 1. In this way, the first heating element 3 and the second heating element 4 can heat the fluid in the flow channel 1, and the heated fluid can flow along the pipe of the fluid circuit to the corresponding position of the air conditioner, thereby heating the air entering the passenger compartment.
[0129] When the air conditioner needs to send warm air into the passenger compartment, the passenger can issue a command to the control device, which then controls the operation of the air conditioning system and the heater 100. The control device can be an onboard host, etc. The passenger can issue the command by touching or toggling a corresponding switch.
[0130] During use, the occupants can send a warm air command according to the required temperature, and the control device will control the air-conditioning system to operate so that fluid passes through the fluid circuit of the air conditioner. Specifically, it can control the water pump to start and control the corresponding switch module to be turned on so that the power supply can supply power to the heater. The action of controlling the water pump to start and the action of controlling the switch module to be turned on can be performed simultaneously, or the water pump can be started first and then the switch module can be controlled to be turned on so that the heater 100 works at the first power.
[0131] After the heater 100 operates at the first power for a certain period of time, for example, 5 seconds, the outlet water temperature of the flow channel 1 is detected. The outlet water temperature of the flow channel 1 can be detected by the first temperature sensor 7 and / or the second temperature sensor 8. When the outlet water temperature is detected by both the first temperature sensor 7 and the second temperature sensor 8, if the detection results are different, the lower detected temperature can be used as the outlet water temperature, or the higher detected temperature can be used as the outlet water temperature.
[0132] The control device is connected to the first temperature sensor 7 and the second temperature sensor 8 and can compare the outlet water temperature detected by the first temperature sensor 7 and / or the second temperature sensor 8 with a target temperature, which is the temperature required by the occupants. If the outlet water temperature is lower than the target temperature, the heater 100 continues to operate at the first power. If the outlet water temperature is greater than or equal to the target temperature, the heater 100 continues to operate at the second power, which is lower than the first power.
[0133] In addition, the switch module may be an IGBT module or the like.
[0134] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
[0135] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
