Description

Technical Field

[0001] This utility model relates to the field of fluid heating technology, and in particular to a heater. Background Technology

[0002] Fluid heaters have a wide range of applications, such as in the semiconductor, photovoltaic solar energy, display panel, testing equipment and instruments, and micro-chemical industries.

[0003] Taking the semiconductor industry as an example, fluid heaters typically consist of heating wires, a cast aluminum shell, and fluid conduits. The cast aluminum shell has excellent thermal conductivity, essentially acting as a metal heat transfer element (or an intermediate heat transfer medium). Generally, the fluid conduits are placed inside the inner cavity of the cast aluminum shell, and the heating wires are then arranged in the remaining portion of the inner cavity.

[0004] When the heating wire is energized, it transfers the heat generated to the cast aluminum shell. The cast aluminum shell, with its excellent thermal conductivity, can then transfer the heat to the fluid in the fluid pipe. The heated fluid can then be pumped or naturally circulated back to the system that needs heating, thus achieving fluid heating.

[0005] However, current heating methods rely on cast aluminum shells. When the remaining space inside the cast aluminum shell is insufficient, the number of heating wires that can be installed is also reduced, resulting in lower heating efficiency. Moreover, the heating requirement can only be met by increasing the volume of the cast aluminum shell. Utility Model Content

[0006] The purpose of this invention is to solve the problem that the heating efficiency of existing fluid heaters is limited by the size of the metal heat transfer components, resulting in low heating efficiency. This invention provides a heater with a simple structure, which does not require the use of an intermediate heat transfer medium and has high heating efficiency.

[0007] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a heater, comprising:

[0008] A fluid conduit includes an inlet and an outlet, the inlet being for fluid to flow into the fluid conduit and the outlet being for fluid to flow out of the fluid conduit; the fluid conduit includes a first bend, one end of which is connected to the inlet and the other end of which is connected to the outlet.

[0009] At least one infrared heating element is disposed at a distance from or in contact with at least a portion of the outer wall of the fluid conduit.

[0010] Using the above technical solution, the heater in this embodiment combines a fluid conduit with an infrared heating element to achieve effective heating. Specifically, one or more infrared heating elements can be directly positioned in contact with or spaced from the fluid conduit, allowing the infrared heating elements to directly heat the fluid conduit without the need for a traditional intermediate medium (such as a cast aluminum shell as a heat transfer metal component) for heat conduction. This effectively improves heating efficiency and reduces energy loss. Furthermore, the heater in this embodiment has a simple structure, thus offering high design flexibility for the fluid conduit. Additionally, the placement of the infrared heating elements allows for a wide range of options, resulting in good applicability. Moreover, the fluid conduit in this embodiment is configured with a curved section, which can accommodate more fluid without occupying more space, effectively improving heating efficiency while also facilitating miniaturization.

[0011] According to another specific embodiment of the present invention, the infrared heating element includes an infrared heating tube.

[0012] According to another specific embodiment of the present invention, the first curved tube portion is spiral-shaped, and the infrared heating tube includes: a first straight tube, the first straight tube extending along a first direction and being spaced apart from or attached to at least a portion of the outer wall of the spiral-shaped first curved tube portion; the first direction is parallel to or intersects with the extending direction of the inlet portion and / or the outlet portion.

[0013] According to another specific embodiment of the present invention, the first curved tube portion defines a first receiving space, the first straight tube is disposed in the first receiving space, and is spaced apart from or attached to at least a portion of the outer wall of the first curved tube portion near the first receiving space.

[0014] According to another specific embodiment of the present invention, the first straight tube and at least a portion of the outer wall of the first curved tube portion away from the first accommodating space are spaced apart or attached together.

[0015] According to another specific embodiment of the present invention, the first curved tube portion is spiral-shaped and has a spiral gap. The infrared heating tube includes a spiral tube, which is accommodated in the spiral gap and is fitted to at least a portion of the outer wall of the spiral-shaped first curved tube portion.

[0016] According to another specific embodiment of the present invention, the first curved tube portion includes a plurality of curved portions along the axial direction, the plurality of curved portions being spaced apart and spirally connected, and the adjacent curved portions defining the spiral gap.

[0017] According to another specific embodiment of the present invention, the first curved tube portion is disc-shaped, and the infrared heating tube includes: a disc-shaped tube, the disc-shaped tube being attached to at least a portion of the outer wall of the disc-shaped first curved tube portion along a second direction; the second direction is parallel to the extending directions of the inlet portion and the outlet portion; or...

[0018] The first curved tube portion is disc-shaped, and the infrared heating tube includes: a bent tube, the bent tube being attached to at least a portion of the outer wall of the disc-shaped first curved tube portion along a second direction; the second direction is parallel to the extending directions of the inlet and the outlet portions; or...

[0019] The first curved tube portion is spiral-shaped, and the infrared heating tube includes an annular tube, which is spaced apart from or attached to at least a portion of the outer wall of the spiral-shaped first curved tube portion.

[0020] According to another specific embodiment of the present invention, the fluid pipeline includes: a second curved pipe section and a straight pipe section, the second curved pipe section and the straight pipe section being connected, one of the straight pipe sections being connected to the inlet section, and the other of the straight pipe sections being connected to the outlet section.

[0021] According to another specific embodiment of the present invention, the infrared heating tube includes: a second straight tube, the second straight tube extending along a third direction and being spaced apart from or attached to the outer wall of the straight tube portion; the third direction is parallel to the extension direction of the straight tube portion.

[0022] According to another specific embodiment of the present invention, the heater further includes: a flexible hose disposed inside the fluid conduit, the flexible hose being configured to allow fluid flow; the fluid conduit is made of quartz, and the flexible hose is made of plastic.

[0023] By adopting the above technical solution, a flexible hose is installed inside the fluid pipeline and the fluid flows inside the hose. When the fluid has a corrosive effect on the material of the fluid pipeline (such as quartz), the fluid can be prevented from corroding the fluid pipeline by flowing inside the hose, thereby extending the service life of the fluid pipeline.

[0024] According to another specific embodiment of the present invention, the outer wall of the hose and the inner wall of the fluid conduit define a second flow channel, the second flow channel being configured for the flow of a second fluid, which is different from the fluid in question.

[0025] By adopting the above technical solution, a second flow channel is set between the outer wall of the hose and the inner wall of the fluid pipe, and a second fluid different from the first fluid flows in the second flow channel. This allows for simultaneous heating of the first fluid and the second fluid (i.e., simultaneous heating of two different fluids), effectively improving heating efficiency and resulting in better economic benefits.

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0045] refer to Figure 1This application provides a heater 100, which includes a fluid conduit 110 and at least one infrared heating element 120.

[0046] First of all, it should be noted that Figure 1 The fluid pipe 110 shown is only one embodiment of this application. This application does not impose specific limitations on the structure of the fluid pipe 110. Various structures of fluid pipe 110 will be described in detail later. At the same time, this application does not impose limitations on the material of the fluid pipe 110. For example, fluid pipes made of quartz, ceramic, metal, or plastic can be used.

[0047] For example, the infrared heating element 120 in this application embodiment includes an infrared heating tube 121. The infrared heating tube 121 is used as an example for description. However, an infrared heating panel or an infrared lamp can also be selected as the infrared heating element 120. This application embodiment does not limit this.

[0048] Furthermore, the wavelength range of the infrared radiation emitted by the infrared heating tube 121 can be selected based on the material properties of the heated equipment, the type of fluid in the fluid pipe, and the actual application scenario; this embodiment does not impose any limitations on this. For example, in the field of optical communication, near-infrared (NIR) radiation with a wavelength range of approximately 0.74 μm to 1.4 μm can be used. As another example, mid-infrared (MIR) radiation with a wavelength range of approximately 1.4 μm to 3 μm can be used for fluids such as water and water-based liquids.

[0049] It should be further noted that the infrared heating tube 121 in this embodiment can be configured in different shapes, such as straight tube, coil tube, bent tube, etc., and can be adapted to the structure of the fluid pipe 110. This will also be described by example later.

[0050] like Figure 1 As shown, the fluid conduit 110 includes an inlet 1101 and an outlet 1102. The inlet 1101 is used to allow fluid (such as liquid, gas, gas-liquid mixture, etc.) to flow into the fluid conduit 110, and the outlet 1102 is used to allow fluid to flow out of the fluid conduit 110.

[0051] For example, Figure 1 The fluid conduit 110 shown is configured as a spiral and has a first receiving space 1100.

[0052] Furthermore, Figure 1Two sets of infrared heating tubes 121 are illustrated, each set comprising eight infrared heating tubes 121. One set of infrared heating tubes 121 is disposed within the first receiving space 1100 of the fluid conduit 110, and surrounds and adheres to the outer wall of the fluid conduit 110 (i.e., the outer wall near the first receiving space 1100). Exemplarily, this set of infrared heating tubes 121 may also be spaced apart from the outer wall of the fluid conduit 110 near the first receiving space 1100. Furthermore, since the eight infrared heating tubes 121 are circumferentially spaced, they can only adhere to a portion of the outer wall near the first receiving space 1100.

[0053] Continue to refer to Figure 1 Another set of infrared heating tubes 121 is disposed outside the heater 100, surrounding the outer wall of the fluid conduit 110 on the other side (i.e., the outer wall of the fluid conduit 110 away from the first receiving space 1100), and the eight infrared heating tubes 121 are respectively spaced apart from this other outer wall. Correspondingly, this other set of infrared heating tubes 121 may also be fitted to the outer wall of the fluid conduit 110 away from the first receiving space 1100. This embodiment of the application does not impose specific limitations on this, and the choice can be made according to the actual application.

[0054] Furthermore, this application embodiment does not impose specific restrictions on the number and placement of infrared heating tubes 121. For example, only one set of infrared heating tubes 121 may be provided, and this set of infrared heating tubes 121 may be placed at any position that is in contact with or spaced from the outer wall of the fluid pipe 110. For another example, each set may include one, two, three, four, or other numbers of infrared heating tubes 121, which can be adaptively selected and adjusted according to the actual application.

[0055] The following describes in detail, with reference to the accompanying drawings, the arrangement schemes between fluid pipes 110 of different structures and corresponding infrared heating tubes 121 using different embodiments.

[0056] Example 1

[0057] refer to Figures 1 to 6 In this first embodiment, the fluid conduit 110 includes a first curved pipe section 111, and the first end 111a of the first curved pipe section 111 is connected to the inlet section 1101, and the second end 111b of the first curved pipe section 111 is connected to the outlet section 1102.

[0058] refer to Figure 1 In some possible embodiments, the first bend 111 of the fluid conduit 110 is helical, and the fluid conduit 110 includes a first bend 111 (i.e., Figure 1The heater 100 shown includes a single-turn first curved tube portion 111. The first curved tube portion 111 defines a first receiving space 1100. The inlet portion 1101 and the outlet portion 1102 are respectively radially (e.g., ...) of the first curved tube portion 111. Figure 1 (Extends in the X direction shown in the figure).

[0059] At the same time, the infrared heating tube 121 is configured as the first linear tube 1211.

[0060] As can be seen, each first straight tube 1211 is along the first direction (e.g. Figure 1 Extending in the Z direction (as shown), the first straight tube 1211 includes a first heating tube body 12111 and a first wiring portion 12112. The first heating tube body 12111 is fitted against the outer wall of the first receiving space 1100 of the first curved tube portion 111, while another set of first heating tube bodies 12111 is spaced apart from the outer wall of the first curved tube portion 111 on the other side away from the first receiving space 1100. Exemplarily, the aforementioned first direction intersects the extending directions of the inlet portion 1101 and the outlet portion 1102.

[0061] When the first wiring part 12112 is energized, the resistance wire (not shown in the figure) of the first heating tube 12111 can generate heat, thereby transferring the heat to the outer wall of the first curved tube 111 by radiation, thereby heating the fluid inside the first curved tube 111.

[0062] refer to Figure 2 In some possible implementations, the first curved section 111 of the fluid conduit 110 is also spiral-shaped, and the first curved section 111 also defines a first receiving space 1100.

[0063] Figure 2 The heater 100 shown is Figure 1 The difference is that the heater 100 includes two first curved tube sections 111, two inlet sections 1101 and two outlet sections 1102. The first end 111a of each first curved tube section 111 is connected to the corresponding inlet section 1101, and the second end 111b of each first curved tube section 111 is connected to the corresponding outlet section 1102.

[0064] In other words, Figure 2 The heater 100 shown includes a double-loop first bend tube section 111, each of which can be used to flow fluid, and the two first bend tube sections 111 are fitted together.

[0065] Furthermore, the infrared heating tube 121 is also configured as a first linear tube 1211.

[0066] For example, it can be seen that, Figure 2Two first straight tubes 1211 are shown, but not limited to two. These two first straight tubes 1211 are along a first direction (e.g., Figure 2 Extending in the Z direction shown, the first heating tube body 12111 of the first straight tube 1211 is fitted to the outer wall of the first receiving space 1100 of the first curved tube portion 111.

[0067] Although Figure 2 Although not shown, it can be understood that the first straight tube 1211 can also be located on the outer wall of the two first curved tube portions 111 away from the first receiving space 1100 (i.e., outside the heater 100). Only one first straight tube 1211 can be provided, or multiple first straight tubes 1211 can be provided, surrounding the outside of the heater 100. Furthermore, the first straight tube 1211 and the outer wall of the corresponding first curved tube portion 111 can be spaced apart or fitted together.

[0068] refer to Figure 3A and Figure 3B In some possible embodiments, the first bend 111 of the fluid conduit 110 is also spiral-shaped, but... Figure 1 The heater 100 shown is different, Figure 3A and Figure 3B The first curved tube section 111 shown has a helical gap 1111 (as shown) Figure 3B As shown), the spiral gap 1111 is used to set an infrared heating tube 121 (i.e., a spiral infrared heating tube 121) with the same shape as the first bent tube section 111.

[0069] It can be understood that the first curved tube section 111 includes a plurality of curved sections 1110. Along the axial direction, the plurality of curved sections 1110 are spaced apart and spirally connected. Then, a connecting gap can be formed between adjacent curved sections 1110, and the gap as a whole can form the aforementioned spiral gap 1111.

[0070] Specifically, such as Figure 3A As shown, the infrared heating tube 121 is configured as a spiral tube 1212, which includes a second heating tube body 12121 and a second wiring portion 12122. The second heating tube body 12121 is spiral-shaped and is disposed in the spiral gap 1111 of the first bent tube portion 111. It can also be understood that the spiral-shaped second heating tube body 12121 is filled in the spiral gap 1111, so that the second heating tube body 12121 is fitted against the outer wall of the first bent tube portion 111.

[0071] When the second wiring part 12122 is energized, the resistance wire (not shown in the figure) of the second heating tube 12121 can generate heat, thereby transferring the heat to the outer wall of the first curved tube part 111 located at the spiral gap 1111 by radiation, thereby heating the fluid in the first curved tube part 111.

[0072] refer to Figure 4A and Figure 4B In some possible embodiments, the first curved section 111 of the fluid conduit 110 is disc-shaped, and, compared to Figures 1 to 3B The first curved tube section 111 shown is... Figure 4A and Figure 4B The first curved tube section 111, which is disc-shaped as shown, is located on the same plane.

[0073] As you can see, Figure 4A and Figure 4B The exemplary disc-shaped first curved tube portion 111 is similar to a "mosquito coil," but is not limited to this shape. (Continue to refer to...) Figure 4A and Figure 4B The inlet 1101 is located outside the first curved tube 111, and the outlet 1102 is located in the middle of the first curved tube 111. However, it is not limited to this. In some other possible embodiments, the outlet 1102 may also be located outside the first curved tube 111, and the inlet 1101 may be located in the middle of the first curved tube 111.

[0074] For example, the inlet portion 1101 and the outlet portion 1102 are respectively along the axial direction of the first curved tube portion 111 (e.g., Figure 4A and Figure 4B (Extended in the Z direction as shown in the diagram).

[0075] Based on this, the infrared heating tube 121 is configured as a disc tube 1213.

[0076] As can be seen, the coil-type tube 1213 includes a third heating tube body 12131 and a third wiring portion 12132. The third heating tube body 12131 is spiral-shaped like a mosquito coil. Figure 4A As shown, the shape of the third heating tube 12131 is approximately the same as that of the first curved tube 111; that is, both are spiral-shaped like a mosquito coil. However, the third heating tube 12131 has fewer coils than the first curved tube 111. However, this application embodiment does not limit this; for example, as... Figure 4B As shown, the shape of the third heating tube 12131 can also be the same as that of the first bent tube 111, that is, the number of turns of the third heating tube 12131 is the same as that of the first bent tube 111.

[0077] The third connection portion 12132 is along the axial direction of the first bent tube portion 111 (e.g., Figure 4A As shown in the Z direction, the extension direction of the third wiring section 12132 is parallel to the extension directions of the inlet section 1101 and the outlet section 1102.

[0078] For ease of explanation, Figure 4A Only exploded views of the fluid conduit 110 and the infrared heating tube 121 are shown, but it can be understood that the third heating tube body 12131 of the disc tube 1213 can be positioned along the second direction (e.g., Figure 4A The direction E shown is attached to the top outer wall of the disc-shaped first curved tube section 111. That is, the outlet section 1102 of the first curved tube section 111 can penetrate and extend into the first gap 12130 of the third heating tube body 12131, so that the third heating tube body 12131 can rest on the top outer wall of the first curved tube section 111. Exemplarily, the second direction is parallel to the first direction described above, and the second direction is parallel to the extending direction of the inlet section 1101 and the outlet section 1102.

[0079] refer to Figure 5 In some possible embodiments, the first curved section 111 of the fluid conduit 110 is disc-shaped, but... Figure 4A Unlike the heater 100 shown, an infrared heating tube 121, either straight (not shown) or bent, can also be used, configured as a bent tube that fits against the top outer wall of the disc-shaped first bent tube portion 111. That is, the infrared heating tube 121 is configured as a bent tube 1214.

[0080] refer to Figure 6 In some possible embodiments, the first curved section 111 of the fluid conduit 110 is helical and annular, and the helical first curved section 111 defines an annular second receiving space 1112 for accommodating an annular infrared heating tube 121.

[0081] Specifically, the infrared heating tube 121 is configured as an annular tube 1215, which includes a fourth heating tube body 12151 and a fourth wiring portion 12152. Exemplarily, the fourth heating tube body 12151 is made of a flexible material, allowing it to be inserted into the annular second receiving space 1112, such that the fourth heating tube body 12151 is spaced apart from or fitted against at least a portion of the outer wall of the first curved tube portion 111 (i.e., the outer wall located in the second receiving space 1112). Exemplarily, only one annular tube 1215 may be provided, or two, three, or more annular tubes 1215 may be provided; this embodiment of the application does not limit this.

[0082] It should be noted that the annular tube 1215 in this application embodiment refers to an infrared heating tube in which the fourth heating tube body 12151 is annular or can be actively bent into annular shape. Any annular tube 1215 that can be set in the second accommodating space 1112 is within the protection scope of this application embodiment.

[0083] In the above embodiment, the fluid flows directly into the fluid pipe 110 (i.e., into the first curved pipe section 111), meaning that the fluid is in contact with the inner wall of the first curved pipe section 111.

[0084] refer to Figure 7A In other possible embodiments, a flexible hose 130 (e.g., a plastic hose) may be provided inside the fluid conduit 110 (e.g., the first bend in the conduit 111). The flexible hose 130 is fixed to the inner wall of the fluid conduit 110 (e.g., the hose is embedded in the fluid conduit 110), and the fluid flows within the flexible hose 130 (that is, the fluid does not come into contact with the fluid conduit 110). Thus, in some applications, when the fluid (e.g., sodium hydroxide solution, etc.) is corrosive to the material of the fluid conduit 110 (e.g., quartz), by allowing the fluid to flow within the flexible hose 130 (e.g., the plastic hose), corrosion of the fluid conduit 110 can be avoided, thereby extending the service life of the fluid conduit 110.

[0085] In other possible implementations, the hose 130 can be directly inserted into the fluid conduit 110, meaning the hose 130 is not fixed to the inner wall of the fluid conduit 110. Therefore, in some scenarios where temporary heating of the fluid is required, and the heated fluid is corrosive to the material of the fluid conduit 110, the hose 130 can be directly inserted into the fluid conduit 110, allowing the fluid to flow within the hose 130. This prevents corrosion of the fluid conduit 110 and extends its service life.

[0086] For example, in this embodiment of the application, the inner walls of the hose 130 and the fluid pipe 110 are fitted together, but this is not a limitation. In other possible implementations, the inner walls of the hose 130 and the fluid pipe 110 may also be spaced apart.

[0087] It is understood that this application does not impose special restrictions on the material of the hose, and can be adapted to the actual application scenario.

[0088] refer to Figure 7BIn other possible embodiments, the hose 130 can be secured to the inner wall of the fluid conduit 110 (e.g., the first bend in the conduit 111) by fasteners such as clamps, and the outer wall of the hose 130 and the inner wall of the fluid conduit 110 define a second flow channel 131 for the passage of a second fluid. The second fluid in the second flow channel 131 is a different type of fluid from the fluid in the hose 130. For example, in some scenarios, the fluid is corrosive to the fluid conduit 110, while the second fluid is not. In this case, the second fluid can flow in the second flow channel 131, allowing the fluid to flow within the hose 130, thus simultaneously heating both fluids and effectively improving the heater's economic efficiency.

[0089]

Example 2

[0090] refer to Figures 8 to 10 The difference between this second embodiment and the first embodiment is that in this second embodiment, the fluid pipe 110 includes a second curved pipe section 112 and a straight pipe section 113, which are connected together. One of the straight pipe sections is connected to the inlet section 1101, and the other straight pipe section is connected to the outlet section 1102.

[0091] For example, the second curved tube portion 112 is a U-shaped tube, but it is not limited to this. It can also be an arc shape, a C-shaped shape, etc. The embodiments of this application do not limit this.

[0092] It should be noted that in this second embodiment, based on the above-described structure of the fluid pipe 110, the straight pipe in the first embodiment, i.e., the second straight pipe, can be used. The arrangement of the second straight pipe is the same as that of the first straight pipe in the first embodiment (e.g., Figure 1 , Figure 2 As shown in the figure, therefore, the same parts will not be described in detail.

[0093] like Figure 8 and Figure 9 As shown, Figure 8 The exemplary fluid conduit 110 is a single-loop three-dimensional structure. Figure 9 The exemplary fluid conduit 110 is a double-loop three-dimensional structure, as shown below. Figure 10 As shown, Figure 10 The fluid conduit 110 shown as an example has a planar structure.

[0094] Furthermore, in this second embodiment, the infrared heating tube 121 can be configured as a second linear tube. The second linear tube is along a third direction (e.g., Figures 8 to 10 The straight tube 113 extends in the direction F shown in the diagram and is spaced apart from or fitted to the outer wall of the straight tube 113. For example, the third direction is parallel to the extension direction of the straight tube 113.

[0095] In some possible implementations, similar to Embodiment 1 above, in Embodiment 2, a flexible hose (e.g., a plastic hose, not shown in the figure, but exemplarily applicable) may also be provided inside the fluid conduit 110 (e.g., the second curved section 112 and the straight section 113). Figure 7A The hose is fixed to the inner wall of the fluid conduit 110 (e.g., the hose is embedded inside the fluid conduit), and the fluid flows inside the hose (meaning the fluid does not come into contact with the fluid conduit 110). Therefore, in some applications, when a fluid (e.g., sodium hydroxide solution) is corrosive to the material of the fluid conduit 110 (e.g., quartz), allowing the fluid to flow inside the hose (e.g., a plastic hose) can prevent corrosion of the fluid conduit 110, thus extending its service life.

[0096] In other possible implementations, the hose can be directly inserted into the fluid conduit 110, meaning the hose is not fixed to the inner wall of the fluid conduit 110. Therefore, in some scenarios where temporary heating of the fluid is required, and the heated fluid is corrosive to the material of the fluid conduit 110, the hose can be directly inserted into the fluid conduit 110, allowing the fluid to flow within the hose. This prevents corrosion of the fluid conduit 110 and extends its service life.

[0097] For example, in this embodiment of the application, the inner walls of the hose and the fluid conduit 110 are fitted together, but this is not a limitation. In other possible implementations, the inner walls of the hose and the fluid conduit 110 may also be spaced apart.

[0098] It is understood that this application does not impose special restrictions on the material of the hose, and can be adapted to the actual application scenario.

[0099] For example, similar to Embodiment 1 above, in this Embodiment 2, the hose can also be secured to the fluid conduit 110 by fasteners such as clamps (e.g., in the second bend section 112 and the straight section 113, although...). Figure 8 and Figure 9 Not shown in the figure, but can be referenced by example. Figure 7B The inner wall of the hose and the outer wall of the hose, along with the inner wall of the fluid conduit 110, define a second flow channel for the flow of a second fluid. The second fluid in the second flow channel is a different type of fluid from the fluid in the hose. For example, in some scenarios, the fluid in the hose is corrosive to the fluid conduit 110, while the second fluid is not. In this case, the second fluid can flow within the second flow channel, allowing both fluids to flow simultaneously within the hose, thus improving the heater's economic efficiency.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
