Description

Technical Field

[0001] This invention relates to the field of heating equipment technology, specifically to a heat-conducting coupling heater made of carbon fiber heating wire and aluminum alloy profile. Background Technology

[0002] Currently, electric heaters widely use heating elements such as electric heating tubes, PTC ceramic heating elements, or carbon fiber heating wires. Among these, carbon fiber heating wires are increasingly used in the heating field due to their advantages such as high electrothermal conversion efficiency, rapid heating, good far-infrared radiation effect, and long service life. In existing electric heating equipment, carbon fiber heating wires are usually fixed to the outer surface of the heat dissipation substrate (such as metal plates, fins, or profiles) by means of straight laying, coiling, or clipping, or embedded in shallow grooves opened in the substrate surface. The heat generated by the heating wire after being energized is transferred to the surrounding environment through convection and radiation, thereby achieving heating. Some products are equipped with temperature control switches, overheat protectors, and other devices to achieve basic temperature control.

[0003] However, in the aforementioned prior art, the carbon fiber heating wire only forms line contact or extremely narrow surface contact with the surface of the heat dissipation substrate or the bottom of the shallow groove, resulting in a very limited actual contact area between the two. Due to the extremely low thermal conductivity of air, the numerous microscopic gaps between the heating wire and the substrate create significant thermal resistance. This causes most of the heat generated by the heating wire to be unable to be effectively conducted to the heat dissipation substrate, instead accumulating around the heating wire and being slowly transferred through the air. This not only leads to low efficiency in heat transfer to the substrate and a slow heating rate, but also results in a significant amount of heat loss during the conduction process, making it difficult to improve the overall heating efficiency of the heater. Summary of the Invention

[0004] The purpose of this invention is to provide a heat-conducting coupling heater using carbon fiber heating wire and aluminum alloy profile, in order to solve the technical problems of low heat conduction efficiency and high heat loss caused by the small contact area and air gap between the carbon fiber heating wire and the heat dissipation substrate in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat-conducting coupling heater of carbon fiber heating wire and aluminum alloy profile, including a shell with a heat outlet window formed at its front end;

[0006] Aluminum alloy profiles are arranged at intervals along the length direction of the housing, each aluminum alloy profile is arranged vertically, and each aluminum alloy profile has a through hole extending along its length direction;

[0007] A connecting and fixing assembly is disposed on the outer sides of both ends of the multiple aluminum alloy profiles in the arrangement direction, for connecting adjacent aluminum alloy profiles together.

[0008] Carbon fiber heating wire, wherein the carbon fiber heating wire is inserted into the through hole of the aluminum alloy profile;

[0009] Metal wire, the metal wire being wound around the outer surface of the carbon fiber heating wire;

[0010] A thermally conductive medium is used to fill the gap between the outer surface of the carbon fiber heating wire and the inner wall of the through hole.

[0011] A temperature control component is disposed inside the housing and electrically connected to the carbon fiber heating wire, and is used to control the power supply and power cut-off of the carbon fiber heating wire.

[0012] Furthermore, a heat insulation layer is formed on the inner wall of the shell, and heat-conducting strips are arranged horizontally spaced on the heat outlet window of the shell, with both ends of the heat-conducting strips rotatably connected to the shell;

[0013] The top of the housing is symmetrically equipped with handles, and the bottom of the housing is equipped with support feet near both sides.

[0014] Furthermore, the aluminum alloy profile is arranged along the length direction of the housing, and the connecting and fixing assembly includes a first mounting plate, a threaded post and a locking bolt. The vertical section of the first mounting plate is L-shaped, and there are two of them. One of them is located at the bottom of one side of the aluminum alloy profile and is close to the heat outlet window, and the other is located on the other side of the aluminum alloy profile and is close to the top. The vertical L-shaped sections of the two first mounting plates face the aluminum alloy profile.

[0015] Furthermore, on the L-shaped vertical and horizontal sections of the first mounting plate, first adjustment holes are provided at intervals along the length direction of the first mounting plate. The threaded post passes through each of the first adjustment holes, and one end of each threaded post passes through the first adjustment hole and is threaded into a hole pre-drilled on each of the aluminum alloy profiles. A protective washer is also fitted on the threaded post, and the two sides of the protective washer abut against the aluminum alloy profile and the first mounting plate, respectively. The locking bolt is threaded onto the threaded post for locking the first mounting plate.

[0016] Furthermore, a second mounting plate is provided on the outer side of the aluminum alloy profile and the first mounting plate respectively. The vertical section of the second mounting plate is also L-shaped. On the vertical and horizontal sections of the L-shape of the second mounting plate, second adjustment holes are provided at intervals along the length direction of the second mounting plate. A support plate is provided at the bottom of the horizontal section of the L-shape of the first mounting plate and the second mounting plate.

[0017] The first mounting plate is symmetrically provided with first locking members near both ends. The first locking members pass through the first adjustment hole on the L-shaped transverse section of the first mounting plate and are screwed into the support plate. The second mounting plate is symmetrically provided with second locking members near both ends. The second locking members pass downward through the second adjustment hole and the support plate and are screwed into the bottom plate of the housing.

[0018] Furthermore, the metal wire is a copper wire, and the metal wire is continuously wound in a spiral shape along the length direction of the carbon fiber heating wire, and the heat-conducting medium is a heat-conducting paste.

[0019] Furthermore, a vertical heat insulation plate is provided inside the housing. The aluminum alloy profile is located in the chamber on the left side of the heat insulation plate. An air switch and a leakage current protector are provided in the chamber on the right side of the heat insulation plate. The air switch and the leakage current protector are located on the side wall of the heat insulation plate. An inspection port is provided on the side plate of the housing near the leakage current protector. A cover plate is provided at the inspection port. The cover plate is rotatably connected to the housing.

[0020] Furthermore, the temperature control component includes a controller, a temperature sensor, and a temperature control panel. The temperature sensor is installed in a chamber on the side wall of the heat insulation plate and near the aluminum alloy profile, for detecting the temperature and transmitting the temperature signal to the controller. The controller is installed in a chamber on the side wall of the heat insulation plate and near the leakage current protector. The temperature control panel is installed on the front panel of the housing and is electrically connected to the controller.

[0021] Furthermore, it also includes a power cord, one end of which is connected to the input terminal of the air switch, the output terminal of the air switch is connected to the input terminal of the residual current device, and the other end of the power cord extends to the outside of the housing and is provided with a power plug.

[0022] Compared with existing technologies, the present invention provides a heat-conducting coupling heater for carbon fiber heating wire and aluminum alloy profile. The carbon fiber heating wire is inserted into the through hole of the aluminum alloy profile, and metal wire is wound around the surface of the heating wire. At the same time, the gap between the outer surface of the heating wire and the inner wall of the through hole is filled with a heat-conducting medium. This changes the original line contact between the heating wire and the inner wall of the profile to a multi-path surface contact through the combined action of the metal wire and the heat-conducting medium. The contact area is effectively increased, the air gap between the heating wire and the profile is filled with the heat-conducting medium, the contact thermal resistance is reduced, and the heat generated by the heating wire can be more smoothly conducted to the entire aluminum alloy profile, reducing heat loss during the conduction process and improving heating efficiency.

[0023] Multiple aluminum alloy profiles are fixed side-by-side inside the housing via connecting and fixing components. The heating wires within each profile can work simultaneously, forming a large, uniform heat dissipation surface for wider heating coverage. The heating wires are completely contained within the through holes of the profiles, preventing damage from external scratches or pressure, and eliminating the risk of electric shock from exposed heating wires, thus enhancing safety. When the heating wires need to be replaced, simply pull the old wire out of the through hole and insert the new wire; there is no need to disassemble the profiles or damage the housing structure, making maintenance simple.

[0024] In addition, by setting a temperature control component to automatically control the power supply to the heating wire, the surface temperature at the heating window of the casing can be maintained within a set safe range; in conjunction with the setting of an air switch and a leakage protector, the power supply can be automatically cut off in case of circuit overload, short circuit or leakage, further ensuring safety in use.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] As attached Figure 1 To be continued Figure 8 As shown:

[0038] Example 1:

[0039] This invention provides a heat-conducting coupling heater using carbon fiber heating wire and aluminum alloy profile, comprising a housing 1, an aluminum alloy profile 3, a connecting and fixing component, a carbon fiber heating wire 4, a metal wire 5, a heat-conducting medium 6, and a temperature control component.

[0040] The casing 1 is the external protective structure of this heater, with a heat outlet window 2 formed at its front end. The casing 1 can be made of metal sheet or flame-retardant plastic. The interior of the casing 1 has a receiving space to accommodate the aluminum alloy profile 3 and other related components. The inner wall of the casing 1 has a heat insulation layer (not shown in the figure). The heat insulation layer can be made of heat insulation cotton or heat insulation felt and attached to the inner wall surface of the casing 1 to reduce heat loss to the outside of the casing 1 in the non-heat outlet direction, so that the heat is concentrated and transported outward through the heat outlet window 2.

[0041] A horizontally spaced heat-conducting strip 7 is provided on the heat outlet window 2. The two ends of the heat-conducting strip 7 are rotatably connected to the housing 1. The heat outlet direction or air outlet angle can be adjusted by rotating the heat-conducting strip 7. Handles 8 are symmetrically installed on the top of the housing 1 for easy carrying and moving of the heater. Support feet 9 are installed near the sides of the bottom of the housing 1 to support the housing 1 on the ground or table, creating a gap between the bottom of the housing 1 and the placement surface, which is conducive to air circulation and moisture prevention. By setting a heat insulation layer, heat loss to the outside of the housing 1 in the non-heat outlet direction is reduced, and heat is more concentratedly transferred to the outside through the heat outlet window 2, reducing unnecessary heat loss. The heat-conducting strip 7 can be rotated and adjusted, allowing users to adjust the heat outlet direction according to actual needs. The handles 8 facilitate the carrying and moving of the heater, and the support feet 9 make the housing 1 more stable, while the bottom gap facilitates air circulation.

[0042] As attached Figure 2 As shown, aluminum alloy profiles 3 are arranged at intervals along the length of the housing 1, with each profile 3 positioned vertically. Each aluminum alloy profile 3 is an extruded aluminum alloy profile with through holes extending along its length. The aluminum alloy profiles 3 can be any of the following: 40 series aluminum alloy profiles, 60 series aluminum alloy profiles, or European standard 60 series aluminum alloy profiles. These profiles are all commercially available standard industrial aluminum profiles with inherent through-hole structures, and can be used directly without additional processing.

[0043] The aluminum alloy profile 3 serves as the main heat dissipation base of this heater. Utilizing the excellent thermal conductivity of aluminum alloy, it can quickly conduct internal heat to the outer surface of the profile for heat dissipation. Multiple aluminum alloy profiles 3 are arranged at intervals along the length of the shell 1, forming a large heat dissipation surface. Appropriate spacing is maintained between the profiles to facilitate air circulation and heat dissipation.

[0044] As attached Figure 2 and Figure 3 As shown, the connecting and fixing components are located on the outer sides of both ends of the multiple aluminum alloy profiles 3 along their arrangement direction, used to connect adjacent aluminum alloy profiles 3 together, so that the multiple aluminum alloy profiles 3 form an integrated heat dissipation module. The connecting and fixing components include a first mounting plate 10, a threaded post 11, and a locking bolt 12. The vertical section of the first mounting plate 10 is L-shaped, and there are two of them. One is located at the bottom of one side of the aluminum alloy profile 3 and near the heat outlet window 2, and the other is located on the other side of the aluminum alloy profile 3 and near the top. The vertical sections of the L-shaped sections of the two first mounting plates 10 face the aluminum alloy profiles 3. The two L-shaped first mounting plates 10 clamp and fix each aluminum alloy profile 3 from the outer sides of both ends of the arrangement direction of the aluminum alloy profiles 3.

[0045] As attached Figure 3As shown, on the L-shaped vertical and horizontal sections of the first mounting plate 10, first adjustment holes 13 are provided at intervals along the length of the first mounting plate 10. Threaded posts 11 pass through each first adjustment hole 13, and one end of each threaded post 11 passes through the first adjustment hole 13 and is threaded into a hole pre-drilled on each aluminum alloy profile 3. That is, each aluminum alloy profile 3 corresponds to one threaded post 11, and one end of the threaded post 11 is screwed into the hole of the aluminum alloy profile 3 to achieve a fixed connection.

[0046] A protective washer 14 is fitted onto the threaded post 11, with its two sides abutting against the aluminum alloy profile 3 and the first mounting plate 10, respectively. The protective washer 14 can be made of rubber or plastic, and its function is twofold: firstly, it acts as a buffer during the tightening process, preventing the first mounting plate 10 from directly contacting the surface of the aluminum alloy profile 3 and causing scratches or indentations; secondly, it fills the small gaps between the aluminum alloy profile 3 and the first mounting plate 10, making the connection tighter and more stable. A locking bolt 12 is threaded onto the threaded post 11 and is used to lock the first mounting plate 10. That is, after tightening the locking bolt 12, the first mounting plate 10 is pressed and fixed to the outer end of the aluminum alloy profile 3. The first adjusting hole 13 is an elongated hole extending along the length of the first mounting plate 10, allowing the threaded post 11 to be adjusted along its length within the first adjusting hole 13, thereby accommodating different arrangements of the number of aluminum alloy profiles 3. By using the first mounting plate 10, threaded post 11 and locking bolt 12, multiple aluminum alloy profiles 3 are fixed side by side into an integral module. This not only ensures that the relative positions of each profile are fixed, but also allows users to increase or decrease the number of profiles according to actual needs and flexibly adjust the width of the heat dissipation surface.

[0047] As attached Figure 4 and Figure 5 As shown, the carbon fiber heating wire 4 is threaded through the through-holes of each aluminum alloy profile 3. The carbon fiber heating wire 4 is preferably made of long-filament carbon fiber, which has advantages such as rapid heating, high electrothermal conversion efficiency, and long service life. The carbon fiber heating wire 4 is routed as follows: it enters from one end of the through-hole of the first aluminum alloy profile 3, exits from the other end, then folds back and enters the through-hole of the second aluminum alloy profile 3, and so on, connecting multiple aluminum alloy profiles 3 in series. In other embodiments, each aluminum alloy profile 3 may also have a separate carbon fiber heating wire 4 threaded through it, with all carbon fiber heating wires 4 connected in parallel. Both ends of the carbon fiber heating wire 4 are led out from the end of the through-hole and connected to the power supply line. After being energized, the carbon fiber heating wire 4 generates Joule heat, which is conducted to the entire aluminum alloy profile 3 through the inner wall of the through-hole.

[0048] As attached Figure 5As shown, the metal wire 5 is wound around the outer surface of the carbon fiber heating wire 4. The metal wire 5 is preferably copper, but aluminum or silver wires, or other metal wires with good thermal conductivity, can also be used. The metal wire 5 is continuously wound in a spiral shape along the length of the carbon fiber heating wire 4, and the spiral pitch and wire diameter can be selected according to actual needs. The metal wire 5 forms a spiral protrusion structure on the outer surface of the carbon fiber heating wire 4. By setting the metal wire 5, on the one hand, the equivalent outer diameter of the carbon fiber heating wire 4 is increased, allowing for more contact points with the inner wall of the through hole; on the other hand, the high thermal conductivity of the metal wire 5 itself makes it an auxiliary heat conduction path, quickly transferring heat from the surface of the carbon fiber heating wire 4 to the inner wall of the through hole. Simultaneously, the spiral winding structure has a certain degree of elasticity, maintaining contact pressure with the inner wall of the through hole during thermal expansion and contraction of the carbon fiber heating wire 4, reducing contact loosening caused by thermal expansion and contraction.

[0049] As attached Figure 5 As shown, the thermally conductive medium 6 fills the gap between the outer surface of the carbon fiber heating wire 4 and the inner wall of the through hole. Since the diameter of the through hole is larger than the diameter of the carbon fiber heating wire 4, an annular gap will inevitably exist after the carbon fiber heating wire 4 is inserted. If no medium is filled, the gap will be filled with air, which has a low thermal conductivity and will form a large contact thermal resistance. In this embodiment, the thermally conductive medium 6 is thermally conductive paste (also known as thermally conductive silicone grease), which has a higher thermal conductivity than air. Filling the gap between the carbon fiber heating wire 4 and the inner wall of the through hole with thermally conductive paste can effectively fill all the microscopic gaps between them, changing the heat conduction mode between the carbon fiber heating wire 4 and the inner wall of the through hole from low thermal conductivity air conduction to high thermal conductivity paste conduction, and significantly reducing the contact thermal resistance. Through the dual effects of increasing the contact area by winding the metal wire 5 and eliminating the air gap by filling with the thermally conductive medium 6, the thermal conductivity between the carbon fiber heating wire 4 and the aluminum alloy profile 3 is improved. The heat generated by the carbon fiber heating wire 4 can be more smoothly conducted to the entire aluminum alloy profile 3, reducing heat loss during the conduction process.

[0050] As attached Figure 2 and Figure 8As shown, a vertical heat insulation plate 20 is installed inside the housing 1. The aluminum alloy profile 3 is located in the chamber on the left side of the heat insulation plate 20, and an air switch 21 and a residual current device (RCD) 22 are installed in the chamber on the right side of the heat insulation plate 20. The air switch 21 and the RCD 22 are mounted on the side wall of the heat insulation plate 20. The heat insulation plate 20 divides the interior of the housing 1 into a heating chamber and an electrical chamber, separating the aluminum alloy profile 3 from electrical components such as the air switch 21 and the RCD 22. This reduces heat transfer from the heating chamber to the electrical chamber, allowing the electrical components to operate at a suitable temperature. Furthermore, it prevents the electrical components from being directly exposed to a high-temperature environment, extending their service life. An inspection port is provided on the side plate of the housing 1 near the RCD 22, and a cover plate 23 is provided at the inspection port. The cover plate 23 is rotatably connected to the housing 1. When it is necessary to inspect or reset the air switch 21 or the RCD 22, the cover plate 23 can be opened for operation without disassembling the housing 1, making it convenient to use.

[0051] As attached Figure 8 As shown, the temperature control component is located inside the housing 1 and electrically connected to the carbon fiber heating wire 4, used to control the energization and de-energization of the carbon fiber heating wire 4. The temperature control component includes a controller 24, a temperature sensor 25, and a temperature control panel 26. The temperature sensor 25 is installed in the cavity on the side wall of the heat insulation plate 20, close to the aluminum alloy profile 3, i.e., the temperature sensor 25 is located on the heating chamber side, used to detect the temperature inside the heating chamber in real time and transmit the temperature signal to the controller 24. The temperature sensor 25 can be a thermocouple or a thermistor.

[0052] The controller 24 is installed on the side wall of the heat insulation plate 20 and in the chamber near the leakage current protector 22, that is, the controller 24 is located on the side of the electrical chamber, which reduces the impact of heat from the heating chamber on the controller 24. The temperature control panel 26 is installed on the front panel of the housing 1 and is electrically connected to the controller 24. The temperature control panel 26 is equipped with temperature setting buttons or knobs and a temperature display screen, and the user can set the desired surface temperature value (e.g., 70°C) through the temperature control panel 26.

[0053] The controller 24 compares the temperature signal fed back by the temperature sensor 25 with the set temperature threshold. When the detected temperature reaches the set value, the controller 24 cuts off the power supply to the carbon fiber heating wire 4; when the detected temperature is lower than the set value (e.g., 5°C lower), the controller 24 reconnects the power supply to the carbon fiber heating wire 4. This on / off control method maintains the surface temperature at the heater's heat outlet 2 within a set safe range. The carbon fiber heating wire 4 itself can reach temperatures of 150°C or even higher, but through the adjustment of the temperature control component, the surface temperature of the profile is limited to a safe value. The temperature sensor 25 monitors the temperature in real time and feeds it back to the controller 24. The controller 24 automatically controls the on / off state of the carbon fiber heating wire 4 according to the set value, achieving automatic temperature regulation and maintaining the surface temperature within a safe range without manual intervention. The temperature control panel 26 allows users to adjust the set temperature according to their actual needs, making operation intuitive and convenient.

[0054] As attached Figure 8 As shown, this heater also includes a power cord 27. One end of the power cord 27 is connected to the input terminal of the air switch 21, and the output terminal of the air switch 21 is connected to the input terminal of the residual current device (RCD) 22. The other end of the power cord 27 extends to the outside of the housing 1 and is equipped with a power plug 28. The power cord 27 passes through the side wall or bottom wall of the housing 1. A cable sleeve or cable clip can be installed at the exit point to prevent the power cord 27 from being cut by the edge of the housing 1, while also serving a fixing and sealing function. The power plug 28 is used to connect to an external power socket to introduce power to the entire heater. The air switch 21 is used to automatically cut off the power supply in case of circuit overload or short circuit, and the RCD 22 is used to automatically cut off the power supply in case of leakage. The two are connected in series in the power supply line to jointly constitute electrical safety protection. By setting the air switch 21 and the RCD 22, the power supply can be automatically cut off in case of circuit overload, short circuit or leakage, which helps to ensure safe use.

[0055] Example 2:

[0056] The difference between this embodiment and Embodiment 1 is as follows: (See attached diagram) Figure 6 and Figure 7 As shown, a second mounting plate 15 is respectively provided on the outer side of the aluminum alloy profile 3 and the first mounting plate 10. The vertical section of the second mounting plate 15 is also L-shaped, and second adjustment holes 16 are provided at intervals along the length of the second mounting plate 15 on the vertical and horizontal sections of the L-shape. A support plate 17 is provided at the bottom of the horizontal section of the L-shape of the first mounting plate 10 and the second mounting plate 15. The support plate 17 is horizontally positioned below the first mounting plate 10 and the second mounting plate 15 to support the first mounting plate 10 and the second mounting plate 15 from the bottom, making the overall structure more stable.

[0057] First mounting plate 10 has first locking members 18 symmetrically arranged near both ends. The first locking members 18 pass through the first adjustment hole 13 on the L-shaped transverse section of the first mounting plate 10 and are screwed into the support plate 17. Second mounting plate 15 has second locking members 19 symmetrically arranged near both ends. The second locking members 19 pass downward through the second adjustment hole 16 and the support plate 17 and are screwed into the bottom plate of the housing 1. The first locking members 18 and the second locking members 19 can be bolts or screws. The first adjustment hole 13 and the second adjustment hole 16 are both elongated holes, allowing the first locking members 18 and the second locking members 19 to move and adjust along their length within the adjustment holes, thereby accommodating different arrangements of different numbers of aluminum alloy profiles 3 and different sizes of housing 1.

[0058] By setting the second mounting plate 15 and the support plate 17, the first mounting plate 10 and the second mounting plate 15 clamp and fix the aluminum alloy profile 3 from both sides, and the support plate 17 provides support from the bottom, making the connection of multiple aluminum alloy profiles 3 more firm and reliable, and the overall heat dissipation module is less likely to loosen or deform during transportation and use. At the same time, the second adjustment hole 16 allows the installation position of the second mounting plate 15 to be flexibly adjusted according to the number and spacing of the aluminum alloy profiles 3, improving the product's versatility and assembly convenience.

[0059] Example 3:

[0060] The difference between this embodiment and Embodiment 1 or Embodiment 2 is as follows: (See attached diagram) Figure 8 As shown, inside the housing 1, an air switch 21 and a residual current device (RCD) 22 are installed in the right-side chamber of the heat insulation plate 20. The air switch 21 and RCD 22 are fixedly installed on the side wall of the heat insulation plate 20. One end of the power cord 27 is connected to the input terminal of the air switch 21, and the output terminal of the air switch 21 is connected to the input terminal of the RCD 22. The output terminal of the RCD 22 is connected to the carbon fiber heating wire 4 and the temperature control component. That is, external power is supplied to the carbon fiber heating wire 4 and the temperature control component after passing through the air switch 21 and the RCD 22 in sequence. Because the air switch 21 and the RCD 22 are connected in series on the power supply line, when an overload, short circuit, or leakage fault occurs in the circuit, the air switch 21 or the RCD 22 automatically trips and cuts off the power supply, protecting the circuit and reducing the risk of electrical faults causing safety accidents.

[0061] The heat insulation plate 20 separates the heating chamber (the area where the aluminum alloy profile 3 is located) from the electrical chamber (the area where the air switch 21, the residual current device 22, and the controller 24 are located), making it difficult for heat from the heating chamber to be transferred to the electrical chamber. This allows the air switch 21, the residual current device 22, and the controller 24 to operate under suitable temperature conditions, reducing the possibility of performance degradation or accelerated aging of electrical components due to high temperatures. Simultaneously, the inspection port and cover 23 on the side panel of the housing 1 near the residual current device 22 allow personnel to reset, inspect, or replace the air switch 21 and the residual current device 22 without disassembling the housing 1, improving maintenance convenience.

[0062] Example 4:

[0063] The difference between this embodiment and embodiments one, two, or three is that two or more carbon fiber heating wires 4 are inserted into the through holes of each aluminum alloy profile 3. Multiple carbon fiber heating wires 4 can be connected in parallel to increase the total heating power, or they can be connected to different temperature control circuits to achieve zoned control. When multiple carbon fiber heating wires 4 are used, each heating wire can be inserted from both ends of the through hole and arranged in parallel inside the through hole. Each heating wire is wound with a metal wire 5, and a heat-conducting medium 6 is filled between each heating wire and the inner wall of the through hole. By setting multiple carbon fiber heating wires 4, some or all of the heating wires can be turned on according to actual heating needs, which is beneficial for achieving power regulation and energy-saving operation.

[0064] Working principle:

[0065] Combined with appendix Figure 1 To be continued Figure 8 The working principle of this invention is as follows:

[0066] When the carbon fiber heating wire 4 is energized, it generates Joule heat. The heat is first conducted to the metal wire 5 wrapped around its outer surface. The metal wire 5, with its high thermal conductivity, quickly conducts the heat to the inner wall of the through hole it contacts. At the same time, the heat-conducting medium 6 filling the gap between the outer surface of the carbon fiber heating wire 4 and the inner wall of the through hole effectively conducts the heat in the gap to the inner wall of the through hole. Under the synergistic effect of the above dual heat conduction paths, the heat generated by the carbon fiber heating wire 4 is efficiently conducted to the entire aluminum alloy profile 3. Multiple aluminum alloy profiles 3 are fixedly connected into a large-area heat dissipation module by connecting and fixing components (first mounting plate 10, threaded post 11, locking bolt 12, and second mounting plate 15, support plate 17, first locking member 18, and second locking member 19). The heat is evenly released to the surrounding space through the surface of each aluminum alloy profile 3 and the heat-conducting strip 7 on the heat outlet window 2, achieving the purpose of heating.

[0067] The temperature sensor 25 of the temperature control component monitors the temperature inside the heating chamber in real time and transmits the signal to the controller 24. The controller 24 controls the on / off state of the carbon fiber heating wire 4 according to the temperature value set on the temperature control panel 26, so that the surface temperature at the heat outlet window 2 of the heater is maintained within the set safe range. The air switch 21 and the leakage protection device 22 automatically cut off the power supply in the event of overload, short circuit or leakage in the circuit to ensure safe use.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
