[0001] This utility model relates to the field of heaters, and more specifically, to a heating component and a heater assembly. Background Technology In the existing technology, heaters come in various types, generally including plate heaters or tube heaters. Tube heaters typically have a chamber formed on the outside of the heating tube for fluid flow. When the fluid flows in the chamber, the heating tube is energized and heats up, thereby heating the fluid.

Simultaneously, due to the design of the flow divider, by reducing the flow rate entering the first inner flow channel and increasing the flow rate entering the first arc-shaped flow channel, the fluid is rationally divided. This effectively improves the situation where the high flow resistance of the first arc-shaped flow channel makes it difficult for fluid to enter, leading to burnout of the outer surface of the first heating tube. This improves the stability and reliability of the heating assembly's operation and reduces maintenance costs. Attached Figure Description

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] Please refer to Figures 1-2 This embodiment provides a heating assembly 100, including: A first heating tube 110, a first flow channel shell 120, and a flow divider plate 130 are provided. The first heating tube 110 has a first inner flow channel 111, and a first flow hole 112 communicating with the first inner flow channel 111 is provided on the tube wall of the first heating tube 110. The first flow channel shell 120 is provided with a first arc-shaped flow channel 123, the first heating tube 110 is inserted into the first flow channel shell 120, the first arc-shaped flow channel 123 surrounds the first heating tube 110, and the first flow hole 112 is exposed outside the first flow channel shell 120. The flow divider plate 130 is provided with a first flow divider hole 133, and the flow divider plate 130 is sealed to the port of the first inner flow channel 111 located in the first arc-shaped flow channel 123. The first flow divider hole 133 communicates with the first inner flow channel 111. The cross-sectional area of ​​the first flow divider hole 133 is smaller than the cross-sectional area of ​​the first inner flow channel 111.

[0025] As described above, the working principle of the heating component 100 in this embodiment is as follows: During normal operation, fluid enters the heating assembly 100 from one side of the flow divider 130. As the fluid flows through the heating assembly 100, it can flow not only within the first arc-shaped flow channel 123, contacting the outer wall of the heating tube for heating, but also within the first inner flow channel 111, contacting the inner wall of the heating tube for heating. This results in a large contact area between the fluid and the heating tube, leading to high heating efficiency and energy utilization. Simultaneously, the design of the flow divider 130 reduces the flow rate entering the first inner flow channel 111 and increases the flow rate entering the first arc-shaped flow channel 123, achieving reasonable fluid distribution. This effectively mitigates the problem of fluid difficulty entering the first arc-shaped flow channel 123 due to its high flow resistance, which could cause external burnout of the first heating tube 110. This improves the stability and reliability of the heating assembly 100 and reduces maintenance costs.

[0026] The details of the heating component 100 of this application are described below by way of example.

[0027] Please refer to Figures 1-2 In this embodiment, optionally, the heating assembly 100 includes a first heating tube 110, a first flow channel shell 120, and a flow divider 130. The first heating tube 110 passes through the first flow channel shell 120, and the first flow divider 130 is installed at one end of the first heating tube 110 and can reduce the flow rate entering the first heating tube 110.

[0028] Optionally, the first heating tube 110 can be configured as a circular tube, having a circular first inner flow channel 111. The first inner flow channel 111 has a first open end 113 and a first closed end 114. A circular first flow hole 112 is provided on the circumferential wall of the first heating tube 110, and the first flow hole 112 connects to the first inner flow channel 111. In other words, one end of the first flow hole 112 is located on the inner wall surface of the circumferential tube wall, and the other end is located on the outer wall surface of the circumferential tube wall, connecting the inner and outer spaces of the first heating tube 110.

[0029] It should be understood that the structural dimensions of the first flow channel shell 120 and the second flow channel shell 320 can be adapted to the size of the heating tube, making the processing flexible, facilitating product changeover, and reducing costs.

[0030] Optionally, the first flow channel shell 120 includes an integral outer shell 121 and multiple arc-shaped plates 122. The outer shell 121 has a circular mounting channel with open ends. Multiple arc-shaped plates 122 are located within the mounting channel, each extending spirally around the center line of the mounting channel. The multiple arc-shaped plates 122 are evenly spaced along the circumference of the mounting channel, dividing the mounting channel to form multiple first arc-shaped flow channels 123. Furthermore, the inner side of each arc-shaped plate 122 is spaced from the center line of the mounting channel, and the multiple arc-shaped plates 122 enclose an assembly space. A first heating tube 110 is inserted into the assembly space, with a clearance fit between the outer wall of the first heating tube 110 and the inner surfaces of the multiple arc-shaped plates 122 to facilitate medium flow. During assembly, the first open end 113 of the first heating tube 110 is inserted into the assembly space, and the first flow hole 112 on the first heating tube 110 is located outside the assembly space, that is, the first closed end 114 of the first heating tube 110 extends out of the assembly space, and at the same time, the first flow hole 112 extends out of the assembly space.

[0031] It should be understood that the number of curved plates 122 is designed as needed, and no specific limitation is made in this embodiment. Obviously, the number of curved plates 122 can be one, two, or three, etc.

[0032] In addition, the outer shell 121 and the arc plate 122 can be processed independently and then assembled into one piece.

[0033] In other embodiments, optionally, the outer peripheral surface of the housing 121 is provided with a positioning plane 124.

[0034] Optionally, the diverter plate 130 includes an integral central plate 131 and four connecting strips 132. The central plate 131 can be a circular plate, and a circular first diverter hole 133 is opened in the center of the central plate 131. The four connecting strips 132 are all fixed to the outer periphery of the central plate 131 and are evenly spaced around the axis of the central plate 131.

[0035] It should be understood that in other embodiments, the number of connecting strips 132 is not limited to four, but may also be one, two, or five, etc. Furthermore, the central plate 131 and the connecting strips 132 may also be fixedly connected in other ways.

[0036] In this embodiment, the diversion plate 130 can be connected to the outer casing 121. Specifically, all the connecting strips 132 are fixedly connected to the outer casing 121, so that the outer casing 121 and the diversion plate 130 cooperate to form four second diversion holes 134. Obviously, when the number of connecting strips 132 changes, the number of second diversion holes 134 changes accordingly. That is, the number of second diversion holes 134 can be selected as needed, and can be one, two, or three, etc. When there are multiple second diversion holes 134, the multiple second diversion holes 134 are evenly spaced around the first diversion hole 133, which can increase the flow rate.

[0037] It should be noted that the manifold 130 can be integrated with the housing 121. For example, the manifold 130 and the housing 121 can be integrally molded by injection molding, which is suitable for mass production and reduces processing costs.

[0038] In this embodiment, after the first heating tube 110 is inserted into the flow channel shell, the first open end 113 of the first heating tube 110 is attached to the flow divider plate 130. Specifically, the end face where the first open end 113 is located is sealed and attached to the central plate 131. The first flow divider hole 133 is connected to the first inner flow channel 111. The cross-sectional area of ​​the first flow divider hole 133 is smaller than the cross-sectional area of ​​the first inner flow channel 111, which can reduce the flow rate entering the first inner flow channel 111. In other words, when both the first flow divider hole 133 and the first inner flow channel 111 are circular holes, the diameter of the first flow divider hole 133 is smaller than the diameter of the first inner flow channel 111. Meanwhile, all the second branch channels are connected to the first arc-shaped flow channel 123. Under the premise of a constant flow rate, when the flow rate entering the first inner flow channel 111 decreases, the flow rate entering the first arc-shaped flow channel 123 increases. In this way, the problem of small flow rate of fluid entering the first arc-shaped flow channel 123 due to the large flow resistance of the arc plate 122 is effectively improved. Sufficient fluid can enter both the first inner flow channel 111 and the first arc-shaped flow channel 123. The inner and outer walls of the heating tube can fully contact the fluid, resulting in high heating efficiency.

[0039] It should be noted that the first arc-shaped flow channel 123 can be configured as a spiral flow channel, which can further increase the heat exchange area.

[0040] In this embodiment, the heating assembly 100 is operated by fluid entering from one side of the flow divider 130. Due to the design of the flow divider 130, the flow rate is reasonably adjusted so that the fluid can smoothly enter the first inner flow through the first flow divider hole 133 and enter the first arc-shaped flow channel 123 through the second flow divider hole 134. This ensures that the fluid can fully contact the outer and inner walls of the heating tube, resulting in high heating efficiency, the heating tube is not easily damaged by dry burning, low failure rate, long service life, and low maintenance cost.

[0041] Please refer to Figures 1-9 This embodiment also provides a heater assembly, which includes a housing 200, a heating element 100, and a heating unit 300. The heating element 100 and the heating unit 300 are connected in series and are both disposed within the housing 200. Fluid enters from the heating element 100, flows through the heating unit 300, and then flows out. By connecting the heating element 100 and the heating unit 300 in series, heating efficiency can be improved. Obviously, the number of heating elements 100 and heating units 300 is not limited to one; they can be designed as needed. This embodiment does not exhaustively list them, but uses one heating element 100 and one heating unit 300 connected in series as an example for explanation.

[0042] Optionally, the housing 200 includes a controller housing 210 and a water chamber housing 220, which are connected and cooperate to clamp the heating assembly 100 and the heating unit 300. For example, the water chamber housing 220 has a first partition 221 inside, and a first notch 222 is provided on the first partition 221. The first partition 221 divides the interior of the water chamber housing 220 into a first groove 223 and a second groove 224. The heating assembly 100 is engaged in the first groove 223, and the heating unit 300 is engaged in the second groove 224. The controller housing 210 has a second partition 211 inside, which divides the controller housing 210 into a third groove 213 and a fourth groove 214. The controller housing 210 can be fixed to the water chamber housing 220 by welding, bolting or bonding. The first groove 223 and the third groove 213 are joined to form a first sealing cavity, and the second groove 224 and the fourth groove 214 are joined to form a second sealing cavity. The first partition 221 and the second partition 211 are sealed together to block the first sealing cavity and the second sealing cavity, and a transition cavity connecting the first sealing cavity and the second sealing cavity is formed at the first notch 222.

[0043] It should be understood that the first groove 223, the second groove 224, the third groove 213 and the third groove 213 can all be provided with a snap-fit ​​surface, which can cooperate with the positioning surface 124 to prevent the heating component 100 and the heating unit 300 from rotating and improve the structural stability.

[0044] To improve sealing, a first sealing ring 400 can be provided between the controller housing 210 and the water chamber housing 220.

[0045] To ensure that the fluid can smoothly enter the second sealing chamber from the first sealing chamber, a second notch 212 can be provided on the second partition 211, and the first notch 222 and the second notch 212 are connected.

[0046] Furthermore, the water chamber shell 220 is provided with a first inlet 225 and a second inlet 226 located on the same side. The first inlet 225 is connected to the first sealing cavity, and the second inlet 226 is connected to the second sealing cavity. The fluid enters the first sealing cavity, then flows through the heating assembly 100, enters the second sealing cavity through the first notch 222, flows through the heating unit 300, and is discharged from the second inlet 226.

[0047] In addition, the water chamber shell 220 is provided with a first assembly countersunk hole 227 and a second assembly countersunk hole 228, which are located on the other side of the water chamber shell 220 opposite to the first inlet and outlet 225.

[0048] Please combine Figures 10-11Optionally, the heating unit 300 includes a second heating tube 310 and a second flow channel shell 320. The second heating tube 310 has a second inner flow channel 311, which has a second open end and a second closed end. A second flow hole 312 communicating with the second inner flow channel 311 is provided on the tube wall of the second heating tube 310. The second open end of the second heating tube 310 passes through the second flow channel shell 320, which has a second arc-shaped flow channel 321 surrounding the second heating tube 310. The second flow hole 312 is located outside the second arc-shaped flow channel 321.

[0049] During assembly, the heating assembly 100 and the heating unit 300 can be connected to the water chamber shell 220 first, and then the controller shell 210 can be connected to the water chamber shell 220, so that the first flow channel shell 120 and the second flow channel shell 320 are both clamped between the controller shell 210 and the water chamber shell 220. That is, the first groove 223 and the third groove 213 cooperate to clamp the first flow channel shell 120, and the second groove 224 and the fourth groove 214 cooperate to clamp the second flow channel shell 320.

[0050] During operation, the fluid enters from the first inlet / outlet 225, flows through the heating assembly 100, enters the second inner flow channel 311 through the second flow hole 312 from the transfer cavity, and simultaneously enters the second arc flow from one side of the second arc flow, and then exits from the second inlet / outlet 226.

[0051] In this embodiment, optionally, the heater assembly further includes a mounting plate 500, which is fixedly connected to the housing 200 by bolts. The mounting plate 500 and the housing 200 cooperate to clamp and fix the first heating tube 110 and the second heating tube 310. That is, the first heating tube 110 is inserted into the first mounting countersunk hole 227, and the second heating tube 310 is inserted into the second mounting countersunk hole 228. The mounting plate 500 is connected to the water chamber shell 220, pressing the first heating tube 110 and the second heating tube 310 against the water chamber shell 220.

[0052] To improve sealing, a second sealing ring 600 can be installed between the first heating tube 110 and the second heating tube 310 and the water chamber shell 220. That is, there can be two second sealing rings 600, which are located in the first assembly countersunk hole 227 and the second assembly countersunk hole 228, respectively.

[0053] Optionally, both the first heating element 110 and the second heating element 310 can be MCH heating elements, which can be directly purchased and obtained with reference to existing known structures, resulting in low cost. To avoid repetition and redundancy, the structure and principle of the first heating element 110 and the second heating element 310 will not be described in detail; it is sufficient that they can convert electrical energy into heat energy.

[0054] In addition, in order to improve the stability of the first heating tube 110 and the second heating tube 310 with the water chamber shell 220, anti-rotation blocks can be set at the closed ends of the first heating tube 110 and the second heating tube 310. The anti-rotation blocks can be engaged with the anti-rotation groove in the assembly countersunk hole.

[0055] It should be noted that the second arc-shaped flow channel 321 can be configured as a spiral flow channel, which can further increase the heat exchange area.

[0056] The heater assembly provided in this embodiment has high heating efficiency, high energy utilization efficiency, and is energy-saving and environmentally friendly.
