[0025] 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.

[0026] like Figure 1 As shown, in one embodiment, the heater 100 includes a shell 1 and a heating component 2; the shell 1 has a first chamber 11 and a second chamber 12, both of which are suitable for accommodating fluid; the heating component 2 is connected to the shell 1 and is arranged between the first chamber 11 and the second chamber 12 so as to be able to exchange heat with the fluid in the first chamber 11 and the fluid in the second chamber 12.

[0027] In the prior art, heating element 2 only has a chamber for containing fluid on one side. Therefore, during operation, heat from the side of heating element 2 closest to the chamber quickly diffuses outward due to easier heat exchange with the fluid within the chamber, thereby lowering the temperature in that area. However, heat from the side of heating element 2 farther from the chamber loses less heat due to the inconvenience of heat exchange with the fluid within the chamber (i.e., heat diffuses outward more slowly), causing the temperature in that area to become excessively high, making it susceptible to burns.

[0028] In the present application, when the fluid in the first chamber 11 and the second chamber 12 is heated by the heating component 2, both sides of the heating component 2 can respectively achieve heat exchange with the fluid in the first chamber 11 and the second chamber 12. In this way, the heat on both sides of the heating component 2 can be quickly removed from the heating component 2, thereby improving the heat dissipation effect of the heating component 2, thereby effectively preventing the heating component 2 from being burned. The configuration of this embodiment is equivalent to providing an additional chamber so that the fluid in the chamber can cool the heating component 2, thereby preventing the heating component 2 from being burned.

[0029] Additionally, the fluid can be either a gas or a liquid.

[0030] like Figure 1 As shown, in one embodiment, the first chamber 11 and the second chamber 12 are respectively located on opposite sides of the heating assembly 2 .

[0031] exist Figure 1 In the illustrated example, the first chamber 11 and the second chamber 12 are spaced apart from each other along the X-axis direction.

[0032] like Figure 1 As shown, in one embodiment, the housing 1 includes a shell 13 and a partition assembly 14. The shell 13 has a accommodating cavity. The partition assembly 14 is arranged in the accommodating cavity and is used to divide the accommodating cavity into several chambers, including a first chamber 11 and a second chamber 12.

[0033] like Figure 1 As shown, in one embodiment, the shell 13 includes an annular side wall 131, a first cover plate 132, a second cover plate 133, a first connecting member 134 and a second connecting member 135; wherein, the first cover plate 132 and the second cover plate 133 are both connected to the annular side wall 131 and respectively close the two end openings of the annular side wall 131. Specifically, the first cover plate 132 is arranged on the end surface of one end of the annular side wall 131, and the second cover plate 133 is arranged on the end surface of the other end of the annular side wall 131; the first connecting member 134 is connected to the first cover plate 132 and is located on the surface of the first cover plate 132 facing away from the second cover plate 133; the second connecting member 135 is connected to the second cover plate 133 and is located on the surface of the second cover plate 133 facing away from the first cover plate 132.

[0034] A first hole 136 is provided on the surface of the first connecting member 134 facing away from the first cover plate 132. The first hole 136 extends through the surface of the first cover plate 132 near the second cover plate 133. In this case, the first hole 136 communicates with the annular hole of the annular side wall 131. A second hole 137 is provided on the surface of the second connecting member 135 facing away from the second cover plate 133. The second hole 137 extends through the surface of the second cover plate 133 near the first cover plate 132. In this case, the second hole 137 communicates with the annular hole of the annular side wall 131. Furthermore, the annular hole of the annular side wall 131 is a hole formed by the annular side wall 131. The first hole 136, the second hole 137, and the annular hole of the annular side wall 131 are connected to form the accommodating cavity of the housing 1.

[0035] In addition, along the circumference of the annular sidewall 131, the annular sidewall 131 includes a first wall panel 138, a second wall panel 139, a third wall panel, and a fourth wall panel. The first wall panel 138, the second wall panel 139, the third wall panel, and the fourth wall panel enclose an annular hole. Furthermore, the first wall panel 138 is spaced apart from the second wall panel 139, and the third wall panel is spaced apart from the fourth wall panel. The first wall panel 138 is connected to the third and fourth wall panels at both ends, and the second wall panel 139 is connected to the third and fourth wall panels at both ends. In one scenario, the first wall panel 138, the second wall panel 139, the third wall panel, and the fourth wall panel can be connected to form a rectangular tube structure, in which case the annular hole is a square hole.

[0036] In addition, the first wall plate 138 , the second wall plate 139 , the third wall plate and the fourth wall plate are all connected to the first cover plate 132 and the second cover plate 133 .

[0037] exist Figure 1 In the embodiment, the first cover plate 132 and the second cover plate 133 are arranged at intervals along the Z axis direction, the first wall plate 138 and the second wall plate 139 are arranged at intervals along the X axis direction, and the third wall plate and the fourth wall plate are arranged at intervals along the Y axis direction.

[0038] like Figure 1 As shown, in one embodiment, the baffle assembly 14 includes a first baffle 141 and a second baffle 142. In the axial direction of the annular sidewall 131 (i.e., the arrangement direction of the first cover plate 132 and the second cover plate 133), the first cover plate 132, the first baffle 141, the second baffle 142, and the second cover plate 133 are sequentially spaced apart. The first baffle 141 is connected to the first wall plate 138, the third wall plate, and the fourth wall plate, and is spaced apart from the second wall plate 139. The second baffle 142 is connected to the first wall plate 138, the third wall plate, and the fourth wall plate, and is spaced apart from the second wall plate 139. The end of the first baffle 141 near the second wall plate 139 and the end of the second baffle 142 near the second wall plate 139 are both connected to the heating assembly 2.

[0039] The first partition plate 141 , the second partition plate 142 , the heating assembly 2 , the first wall plate 138 , the third wall plate and the fourth wall plate enclose a first chamber 11 . Furthermore, the second chamber 12 is located between the second wall plate 139 and the heating assembly 2 .

[0040] like Figure 1 As shown, in one embodiment, the housing 1 further has an input cavity 15 and an output cavity 16; both the input cavity 15 and the output cavity 16 are connected to the first chamber 11; the input cavity 15 forms a first opening on the outer surface of the housing 1, and the output cavity 16 forms a second opening on the outer surface of the housing 1. The first opening is the input port of the accommodating cavity, and the second opening is the output port of the accommodating cavity.

[0041] exist Figure 1 In the example shown, the input chamber 15 includes at least a portion of the space where the annular hole is located between the first partition plate 141 and the first cover plate 132 and the first hole 136; the output chamber 16 includes at least a portion of the space where the annular hole is located between the second partition plate 142 and the second cover plate 133 and the second hole 137.

[0042] In addition, a first connecting hole 143 is provided on the first partition plate 141 . The first connecting hole 143 passes through the first partition plate 141 along the axial direction of the annular side wall 131 . At this time, the first connecting hole 143 connects the first chamber 11 and the input chamber 15 .

[0043] The second partition plate 142 is provided with a second connecting hole 144 , which passes through the second partition plate 142 along the axial direction of the annular side wall 131 . At this time, the second connecting hole 144 communicates with the second chamber 12 and the output chamber 16 .

[0044] like Figure 1 As shown, in one embodiment, the housing 1 further has a first communicating hole 17 and a second communicating hole 18. The first communicating hole 17 connects the second chamber 12 and the input chamber 15, respectively. That is, the first communicating hole 17 connects with the second chamber 12 and the input chamber 15, so that the second chamber 12 and the input chamber 15 can communicate through the first communicating hole 17. The second communicating hole 18 connects the second chamber 12 and the output chamber 16, respectively. That is, the second communicating hole 18 connects with the second chamber 12 and the output chamber 16, so that the second chamber 12 and the output chamber 16 can communicate through the second communicating hole 18. In addition, the heater 100 further includes a switch assembly 3, which is switchable between a first state and a second state. When the switch assembly 3 is in the first state, the switch assembly 3 closes the first communicating hole 17; when the switch assembly 3 is in the second state, the switch assembly 3 opens the first communicating hole 17.

[0045] When the switch assembly 3 closes the first communicating hole 17, the fluid in the input chamber 15 cannot flow from the first communicating hole 17 to the second chamber 12; when the switch assembly 3 opens the first communicating hole 17, the fluid in the input chamber 15 can flow from the first communicating hole 17 to the second chamber 12.

[0046] The first communicating hole 17 connecting the second chamber 12 and the input chamber 15 may mean that the first communicating hole 17 penetrates the surface enclosed to form the second chamber 12 and the surface enclosed to form the input chamber 15. The second communicating hole 18 connecting the second chamber 12 and the output chamber 16 may mean that the second communicating hole 18 penetrates the surface enclosed to form the second chamber 12 and the surface enclosed to form the output chamber 16.

[0047] exist Figure 1 In the example shown, the first communication hole 17 may be a portion of the space between the first partition plate 141 and the first cover plate 132 , and the second communication hole 18 may be a portion of the space between the second partition plate 142 and the second wall plate 139 .

[0048] In one embodiment, the switch assembly 3 is adapted to sense the pressure in the input chamber 15 so as to switch between a first state and a second state; wherein, when the pressure in the input chamber 15 is less than a predetermined value, the switch assembly 3 is in the first state; and when the pressure in the input chamber 15 is greater than or equal to the predetermined value, the switch assembly 3 is in the second state.

[0049] When the pressure of the input chamber 15 is less than a predetermined value, the flow rate of the fluid is small. After the fluid enters the input chamber 15, it cannot enter the second chamber 12 from the input chamber 15. Subsequently, the fluid enters the first chamber 11 from the input chamber 15, and then enters the output chamber 16 from the first chamber 11, and finally flows out of the heater 100 from the output chamber 16.

[0050] When the pressure of the input chamber 15 is greater than or equal to a predetermined value, the flow rate of the fluid is large. After the fluid enters the input chamber 15, it can enter the second chamber 12 from the input chamber 15. Subsequently, the fluid in the second chamber 12 will enter the output chamber 16. In addition, after the fluid reaches the input chamber 15, it can also enter the first chamber 11 from the input chamber 15, and then enter the output chamber 16 from the first chamber 11. Finally, the fluid can flow out of the heater 100 from the output chamber 16.

[0051] like Figure 1As shown, in one embodiment, the switch assembly 3 includes an elastic member 31 and a piston 32; the elastic member 31 connects the housing 1 and the piston 32; when the switch assembly 3 is in a first state, the piston 32 closes the first communicating hole 17; when the switch assembly 3 is in a second state, the piston 32 opens the first communicating hole 17, and the elastic member 31 is in an elastically deformed state. Subsequently, when the pressure in the input chamber 15 decreases to less than a predetermined value, the piston 32 can close the first communicating hole 17 under the elastic force of the elastic member 31.

[0052] In one embodiment, when the piston 32 closes the first communicating hole 17, the piston 32 can be located between the first partition plate 141 and the first cover plate 132, and the piston 32 is in sealing contact with the first partition plate 141, the first cover plate 132, the third wall plate and the fourth wall plate; when the piston 32 opens the first communicating hole 17, the piston 32 can be moved into the second chamber 12.

[0053] like Figure 1 As shown, in one embodiment, one end of the elastic member 31 is connected to the second wall plate 139, and the other end of the elastic member 31 is connected to the piston 32. When the pressure in the input chamber 15 is greater than or equal to a predetermined value, the fluid in the input chamber 15 will push the piston 32 toward the second wall plate 139, at which time the elastic member 31 can be compressed, thereby causing the elastic member 31 to elastically deform. When the pressure in the input chamber 15 is less than the predetermined value, the elastic member 31 can push the piston 32 toward the first wall plate 138 until the first connecting hole 17 is closed. Of course, in other embodiments, the elastic member 31 can also be connected to the first wall plate 138. When the pressure in the input chamber 15 is greater than or equal to the predetermined value, the fluid in the input chamber 15 will push the piston 32 toward the second wall plate 139, at which time the elastic member 31 can be stretched, thereby causing the elastic member 31 to elastically deform.

[0054] In one embodiment, the elastic member 31 may be a coil spring. In addition, the material of the piston 32 may be rubber, stainless steel or a plastic layer.

[0055] like Figure 2 As shown, in one embodiment, the heating component 2 includes a heating element 21, a first insulating layer 22, a second insulating layer 23, a first heat-conducting layer 24 and a second heat-conducting layer 25; the heating element 21 is capable of generating heat when powered on; the first insulating layer 22 is arranged on the surface of the heating element 21 close to the first chamber 11; the first heat-conducting layer 24 is arranged on the surface of the first insulating layer 22 close to the first chamber 11; the second insulating layer 23 is arranged on the surface of the heating element 21 close to the second chamber 12; and the second heat-conducting layer 25 is arranged on the surface of the second insulating layer 23 close to the second chamber 12.

[0056] The heating element 21 can generate heat when powered on, thereby heating the fluid in the first chamber 11 and the second chamber 12 .

[0057] In addition, by providing the first insulating layer 22, the second insulating layer 23, the first heat-conducting layer 24 and the second heat-conducting layer 25, the heat exchange efficiency between the heating element 21 and the fluid in the first chamber 11 and the second chamber 12 can be improved, and leakage can be avoided, thereby improving the safety performance of the heater 100.

[0058] It should be noted that the first insulating layer 22 may completely cover the surface of the heating element 21 close to the first chamber 11 , and the second insulating layer 23 may completely cover the surface of the heating element 21 close to the second chamber 12 .

[0059] In one embodiment, the heating element 21 may be a film-shaped structure. Of course, the heating element 21 may also be a PTC or the like.

[0060] The first insulating layer 22 can be a silicon carbide layer, and the second insulating layer 23 can also be a silicon carbide layer. The first thermally conductive layer 24 can be an aluminum plate or a stainless steel plate, and the second thermally conductive layer 25 can be an aluminum plate or a stainless steel plate. In the Z-axis direction, the two ends of the heating element 21 can be connected to the first partition 141 and the second partition 142, respectively. The two ends of the first insulating layer 24 can be connected to the first partition 141 and the second partition 142, respectively. The two ends of the second insulating layer 25 can be connected to the first partition 141 and the second partition 142, respectively.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment, the heater 100 further includes heat dissipation fins 4, which are disposed on the second heat conducting layer 25 and located in the second chamber 12, thereby further improving the heat exchange effect between the heating element 21 and the fluid in the second chamber 12.

[0062] The heat dissipation fins 4 may be made of aluminum plates or stainless steel plates.

[0063] In addition, after assembly, the heat dissipation teeth are spaced apart from the second wall plate 139 .

[0064] like Figure 1 As shown, in one embodiment, there are multiple heat dissipation teeth, and the heat dissipation fins 4 are sequentially spaced apart along the axial direction of the annular side wall 131 .

[0065] like Figure 1 and Figure 2 As shown, in one embodiment, the heater 100 further includes a temperature sensor 5, which is disposed on the heating assembly 2 and located in the second chamber 12. The temperature sensor 5 can be disposed on the second heat-conducting layer 25 and close to the output chamber 16.

[0066] In addition, each heat dissipation fin 4 is located between the temperature sensor 5 and the first cover plate 132 .

[0067] It should be understood that the above-mentioned related designs can also be replaced by other methods, such as:

[0068] In other embodiments, the partition assembly 14 may further include a third partition and a fourth partition, wherein the third partition is disposed between the first partition 141 and the first cover plate 132, and the third partition is connected to the third wall plate and the fourth wall plate, respectively. The third partition, the first wall plate 138, and the second wall plate 139 are spaced apart. The fourth partition is connected to the second partition 142, the second wall plate 139, the third wall plate, and the fourth wall plate. The first cover plate 132, the fourth partition, and the second cover plate 133 are spaced apart in sequence.

[0069] At this time, the first connecting part, the first cover plate 132, the first partition plate 141, the third partition plate and the first wall plate 138 enclose the input chamber 15, the second connecting part, the second cover plate 133, the second partition plate 142, the fourth partition plate, the first wall plate 138 and the second wall plate 139 enclose the input chamber 15, and the third partition plate, the fourth partition plate, the second wall plate 139, the third wall plate, the fourth wall plate, the first cover plate 132 and the heating component 2 enclose the second chamber 12.

[0070] The first communication hole 17 is provided on the third partition plate and extends through the third partition plate along the alignment of the first wall plate 138 and the second wall plate 139. The second communication hole 18 is provided on the fourth partition plate and extends through the fourth partition plate along the alignment of the first cover plate 132 and the second cover plate 133. In this embodiment, the switch assembly 3 can be located between the third partition plate and the second wall plate 139. In this case, the elastic member 31 can be connected to the second wall plate, with the piston 32 located between the elastic member and the third partition plate. The piston 32 can contact the third partition plate to close the first communication hole 17. The piston 32 can move closer to the second wall plate to open the first communication hole 17.
