Description

Technical Field

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

[0002] As people's demands for comfortable living environments increase, panel heaters have gradually become one of the mainstream products in the market due to their high efficiency, energy saving, and aesthetic appeal. Currently, most aluminum panel heaters on the market are produced using aluminum extrusion molding, which involves extruding aluminum material into a specific shape using a mold, and then embedding or fixing the heating element inside the profile. While this process is mature, it still has the following technical limitations: Width limitations and aesthetic shortcomings: Due to the physical limitations of aluminum extrusion dies, the width of the profiles cannot be significantly increased, thus restricting the overall size of the heater. Increasing the number of heating elements requires a larger heater, necessitating an increase in the size of the aluminum material and consequently, the size of the die. However, the die cannot be increased indefinitely due to cost and physical constraints. Therefore, the die limits the size of the heater and the number of heating elements. Furthermore, profiles formed by die extrusion typically have uneven surfaces or reinforcing ribs, making it difficult to achieve a completely flat appearance, thus reducing the product's aesthetics and market acceptance.

[0003] Structural deformation and high cost: During aluminum extrusion, uneven stress can easily cause panel deformation. To enhance structural stability, multiple reinforcing ribs and increased thickness are required inside the profile. This not only increases the complexity and manufacturing cost of the mold but also increases the amount of material used. At the same time, the special nature of the mold limits the choice of aluminum material. The aluminum material must be selected from those suitable for mold production, further increasing production costs.

[0004] Therefore, there is an urgent need for a panel heater that can overcome mold limitations, reduce costs, and improve product aesthetics. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a plate heater made of heating tubes. A top plate and a bottom plate are fixedly connected to the top and bottom of a frame, respectively, forming the internal space of a first shell. The overall structure of the first shell is simple. When the number of heating tubes increases, the size of the first shell (including the frame, top plate, and bottom plate) is correspondingly increased to accommodate the heating tubes, thus the external dimensions of the plate heater are not limited. The bottom plate is flat, aesthetically pleasing, and thinner, saving on mold costs and the amount of material required for the first shell, resulting in a lower overall cost.

[0006] This utility model provides a plate heater made of heating tubes, including a heating assembly. The heating assembly includes a first shell and multiple heating tubes disposed within the first shell. The first shell includes a frame, a top plate, and a bottom plate. The top plate and the bottom plate are fixedly connected to the top and bottom of the frame, respectively, and enclose the internal space of the first shell. The bottom plate is a flat plate, and the multiple heating tubes are fixedly connected to the bottom plate and disposed within the internal space of the first shell. The heating tubes are arranged parallel to each other and with equal spacing.

[0007] Furthermore, the first housing is rectangular, the frame is square, the top plate is flat, the heating element is straight, and the heating element is set to be parallel to the inner wall of the frame.

[0008] Furthermore, the first housing is cylindrical, the frame is a circular frame, the top plate is a flat plate, and the heating element includes an arc portion and a straight tube portion; the arc portion is fixedly connected to the bottom plate and parallel to the inner wall of the frame, the center of multiple arc portions coincides with the center of the frame, and the diameter of each arc portion is different; the straight tube portion is fixedly connected to one end of the arc portion, and the straight tube portion is inclined upward.

[0009] Furthermore, the projected area of ​​the base plate is larger than the projected area of ​​the frame body and the top plate, and the base plate is used to dissipate the heat of the heating tube.

[0010] Furthermore, the heating element also includes a heat insulation layer, which is disposed in the internal space of the first housing and above the heating tube near the top plate. The heat insulation layer is heat insulation cotton.

[0011] Furthermore, the panel heater also includes a lighting assembly and a connecting pipe. The lighting assembly includes a second housing and a light strip disposed within the second housing. The second housing is configured to surround the side of the first housing. The connecting pipe is a hollow tube, and its two ends are fixedly connected to the side of the frame body and the second housing, respectively.

[0012] Furthermore, the second housing includes an upper frame and a lampshade. The bottom of the upper frame has a groove surrounding the first housing. The lamp strip is fixedly disposed in the groove. The top of the lampshade protrudes and is inserted into the groove for fixed connection.

[0013] Furthermore, the bottom surface of the second housing and the bottom surface of the base plate are located on the same horizontal plane, and the distance between the second housing and the frame body is greater than or equal to the distance between the second housing and the base plate.

[0014] Furthermore, there is a gap between the second housing and the base plate, and the shape of the second housing is configured to surround the base plate at equal intervals.

[0015] Furthermore, the panel heater also includes a hanging assembly, which includes a first hanger and a second hanger. The first hanger and the second hanger are detachably connected by a snap fastener. The first hanger is fixedly connected to the top plate, and the second hanger is fixedly connected to the ceiling or wall. Wiring holes are provided on the first hanger and the second hanger.

[0016] In summary, this embodiment of the invention uses a top plate and a bottom plate fixedly connected to the top and bottom of the frame body, respectively, to form the internal space of the first shell. The overall structure of the first shell is simple. When the number of heating elements increases, the size of the first shell (including the frame body, top plate, and bottom plate) is increased accordingly to accommodate the heating elements, thus the appearance size of the plate heater is not limited. The bottom plate is flat, aesthetically pleasing, and thinner, saving on mold costs and the amount of material required for the first shell, resulting in a lower overall cost.

[0017] Furthermore, by fixing multiple heating elements parallel to each other and at equal intervals to the base plate, the heating elements not only generate heat but also act as reinforcing ribs, strengthening the structural strength of the base plate and preventing deformation. The base plate is flat, aesthetically pleasing, and thinner, saving not only on the cost of the base plate mold but also on the amount of material required for the base plate. This allows for a wider range of material choices for the base plate, resulting in a lower overall cost.

[0018] Moreover, the first shell can be rectangular or cylindrical in shape to suit different appearance requirements.

[0019] Moreover, the projected area of ​​the base plate is larger than that of the frame and the top plate. The base plate is used to dissipate the heat of the heating element, and the large area of ​​the base plate helps to improve the heat dissipation efficiency.

[0020] Furthermore, the base plate is not limited to mold making, allowing for a wider range of manufacturing methods, including cheaper options. The base plate is flat, without any raised or recessed structures or reinforcing ribs, achieving a completely smooth appearance. There's also no need to specifically select the type of aluminum used in the mold; a wider selection of aluminum materials is available, including lower-cost options. The heating element is directly fixed to the base plate, acting as reinforcement, resulting in a more aesthetically pleasing base plate that is more readily accepted by the market.

[0033] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0037] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0038] The following detailed explanation uses specific examples: like Figures 1 to 5 As shown, the first embodiment of this utility model provides a plate heater made of heating tubes 120, including a heating assembly 100. The heating assembly 100 includes a first housing 110 and multiple heating tubes 120 disposed within the first housing 110. The first housing 110 includes a frame body 111, a top plate 112, and a bottom plate 113. The top plate 112 and the bottom plate 113 are fixedly connected to the top and bottom of the frame body 111, respectively, and enclose the internal space of the first housing 110. The bottom plate 113 is a flat plate, and the multiple heating tubes 120 are fixedly connected to the bottom plate 113 and disposed within the internal space of the first housing 110. The heating tubes 120 are arranged in parallel with equal spacing.

[0039] Specifically, the heating element 120 is directly fixed to the base plate 113, so the base plate 113 can be a flat panel. The flat panel structure is simple and does not require extrusion molding; it can be directly cut, eliminating the risk of deformation during manufacturing. In existing technologies, when the base plate 113 is manufactured using an extrusion mold, it is prone to deformation during the pressing process, thus requiring multiple reinforcing ribs. However, in this embodiment, the base plate 113 is a flat panel, so there is no need to add reinforcing ribs during its manufacture; it can be directly cut and shaped. The heating element 120, after being fixed to the base plate 113, also acts as a reinforcing rib, increasing the structural strength of the base plate 113.

[0040] In this embodiment, the first housing 110 is rectangular, the frame 111 is a square frame made of aluminum profile, the top plate 112 is a flat plate, and the heating element 120 is a straight tube, which is set to be parallel to the inner wall surface of the frame 111. The bottom plate 113 is rectangular, which is suitable for different appearance requirements.

[0041] Specifically, the top plate 112 is also called the sealing plate or back plate, the heating tube 120 is an aluminum heating tube 120, and the first housing 110 is composed of a frame body 111 spliced ​​from aluminum profiles, a top plate 112 made of aluminum plate and a bottom plate 113.

[0042] In this embodiment, the projected area of ​​the base plate 113 is larger than the projected area of ​​the frame body 111 and the top plate 112. The base plate 113 is used to dissipate the heat of the heating tube 120.

[0043] Specifically, a larger projected area for the base plate 113 increases the heat dissipation area. In this embodiment, the first housing 110 (including the frame 111, top plate 112, and base plate 113) has a simple structure. The frame 111 is constructed from aluminum profiles, and its enclosed area can be increased by extending the profile length. The top plate 112 and base plate 113 can be manufactured without molds, thus avoiding size limitations imposed by mold manufacturing methods. With an increased number of heating elements 120, the lateral dimension of the first housing 110 can be set larger than in the prior art. The corresponding dimensions of the frame 111, top plate 112, and base plate 113 can be increased to accommodate the number of heating elements 120.

[0044] In this embodiment, the heating component 100 further includes a heat insulation layer 130, which is disposed in the internal space of the first housing 110 and is located above the heating tube 120 near the top plate 112. The heat insulation layer 130 is heat insulation cotton.

[0045] In this embodiment, the panel heater also includes a light assembly 200 and a connecting pipe 300. The light assembly 200 includes a second housing 210 and a light strip 220 disposed in the second housing 210. The second housing 210 is configured to surround the side of the first housing 110. The connecting pipe 300 is a hollow tube, and the two ends of the connecting pipe 300 are fixedly connected to the side of the frame body 111 and the second housing 210, respectively.

[0046] Specifically, the connecting tube 300 is a hollow bolt, with both ends fixedly connected to the first housing 110 and the second housing 210 respectively via press-fit nuts. Specifically, both ends are fixedly connected to the side of the upper frame 211 and the side of the frame 111 respectively. The main function of the connecting tube 300 is connection; its hollow design also allows for the routing of lamp wires, resulting in a cleaner and less exposed appearance.

[0047] In this embodiment, the second housing 210 includes an upper frame 211 and a lampshade 212. The bottom of the upper frame 211 has a groove 2111 that surrounds the first housing 110. The lamp strip 220 is fixedly disposed in the groove 2111. The top of the lampshade 212 protrudes and is inserted into the groove 2111 for fixed connection.

[0048] Specifically, the upper frame 211 is made of aluminum profile, the lampshade 212 is a convex-shaped lampshade 212, and the light emitted by the light strip 220 is emitted after being reflected by the lampshade 212.

[0049] In this embodiment, the bottom surface of the second housing 210 and the bottom surface of the base plate 113 are located on the same horizontal plane, and the distance between the second housing 210 and the frame body 111 is greater than or equal to the distance between the second housing 210 and the base plate 113.

[0050] In this embodiment, there is a gap between the second housing 210 and the base plate 113, and the shape of the second housing 210 is set to surround the base plate 113 with equal spacing.

[0051] Specifically, the distance between the second housing 210 and the base plate 113 can prevent the second housing 210 from being too close to the first housing 110. When the heating tube 120 is working, some of the heat will be dissipated from the frame body 111 to the side. If the second housing 210 is too close to the first housing 110, this heat will heat the LED beads of the light strip 220 and reduce the service life of the light strip 220.

[0052] In this embodiment, the panel heater also includes a hanging assembly 400, which includes a first hanger 410 and a second hanger 420. The first hanger 410 and the second hanger 420 are detachably connected by a snap fastener. The first hanger 410 is fixedly connected to the top plate 112, and the second hanger 420 is fixedly connected to the ceiling or wall. Wiring holes 411 are provided on the first hanger 410 and the second hanger 420.

[0053] The plate heater in this embodiment mainly solves the following two problems: 1. Existing aluminum panel heaters on the market are generally produced using aluminum extrusion molds. However, due to mold limitations, the profiles cannot be made wider. In this embodiment, the top plate 112 and the bottom plate 113 are fixedly connected to the top and bottom of the frame body 111, respectively, forming the internal space of the first shell 110. The overall structure of the first shell 110 is simple. When the number of heating elements 120 increases, the size of the first shell 110 (including the frame body 111, top plate 112, and bottom plate 113) is increased accordingly to accommodate the heating elements 120, thus the appearance size of the panel heater is not limited. The bottom plate 113 is flat, aesthetically pleasing, and thinner, saving on mold costs and the amount of material required for the first shell 110, resulting in a lower overall cost.

[0054] 2. Aluminum extrusion die production is prone to deformation. To strengthen the panel structure and prevent deformation, multiple reinforcing ribs are required, along with increased thickness, leading to higher die and material costs. In this embodiment, the base plate 113 is a flat plate without any protrusions or reinforcing ribs, achieving a completely flat appearance. The three heating elements 120 are directly or indirectly welded to the base plate 113, acting as reinforcing ribs. The base plate 113 is more aesthetically pleasing and more readily accepted by the market.

[0055] like Figures 6 to 10 As shown, the second embodiment of this utility model provides a plate heater made of a heating element 120. The main difference from the first embodiment is that the first housing 110 in the second embodiment is cylindrical, and the heating element 120 includes an arc portion 121 and a straight tube portion 122. The base plate 113 is circular, suitable for different appearance requirements.

[0056] In this embodiment, the first housing 110 is cylindrical, the frame body 111 is a circular frame formed by aluminum profiles, the top plate 112 is a flat plate, and the heating tube 120 includes an arc portion 121 and a straight tube portion 122. The arc portion 121 is fixedly connected to the bottom plate 113 and is parallel to the inner wall surface of the frame body 111. The centers of the multiple arc portions 121 coincide with the center of the frame body 111, and the diameter of each arc portion 121 is different. The straight tube portion 122 is fixedly connected to one end of the arc portion 121 and is inclined upward.

[0057] Specifically, multiple heating tubes 120 are evenly spaced on the base plate 113. On the one hand, this can improve the heat dissipation effect, making it more uniform and efficient. On the other hand, it can also serve as reinforcing ribs to improve the structural strength of the base plate 113.

[0058] In summary, the present invention uses a top plate 112 and a bottom plate 113 to be fixedly connected to the top and bottom of the frame body 111, respectively, to form the internal space of the first housing 110. The overall structure of the first housing 110 is simple. When the number of heating tubes 120 increases, the size of the first housing 110 (including the frame body 111, top plate 112 and bottom plate 113) is increased accordingly to match the heating tubes 120. The appearance size of the plate heater is not limited.

[0059] Furthermore, by fixing multiple heating elements 120 parallel to each other and at equal intervals to the base plate 113, the heating elements 120 not only provide heat but also act as reinforcing ribs, strengthening the structural strength of the base plate 113 and preventing deformation. The base plate 113 is flat, aesthetically pleasing, and thinner, saving not only the cost of the base plate 113 mold but also the amount of material required for the base plate 113. This allows for a wider range of material choices for the base plate 113, resulting in a lower overall cost.

[0060] Moreover, the first housing 110 can be in the shape of a cuboid or a cylinder to accommodate different appearance requirements.

[0061] Moreover, the projected area of ​​the base plate 113 is larger than that of the frame body 111 and the top plate 112. The base plate 113 is used to dissipate the heat of the heating tube 120. The large area of ​​the base plate 113 is conducive to improving heat dissipation efficiency.

[0062] Furthermore, the base plate 113 is not limited to mold making, allowing for a wider range of manufacturing methods, including cheaper options. The base plate 113 is flat, without any raised or recessed structures or reinforcing ribs, achieving a completely smooth appearance. The type of aluminum used in the mold is also less critical, allowing for a wider selection of lower-cost aluminum materials. The heating element 120 is directly fixed to the base plate 113, acting as a reinforcing rib, making the base plate 113 more aesthetically pleasing and more readily accepted by the market.

[0063] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
