[0023] Example 1, Figures 1-4 and Figures 8-11 The present invention provides a technical solution: a heat dissipation structure for an electric heating wall panel with uniform heat dissipation, comprising: The electric heating base layer 1 has a back panel 6 attached to the side away from the room. The electric heating base layer 1 is equipped with a front and rear air circulation structure, with the airflow direction facing forward. The electric heating base layer 1 is fitted with a hot air flow cavity plate 2 on the side closest to the room, and its front and rear ends are connected to the same side of the front and rear air circulation structure. The front and rear ends of the hot air flow cavity plate 2 are detachably fixed to the edge of the back plate 6; A heat-equalizing layer 3 is attached to the side of the hot air flow cavity plate 2 closest to the room, and a heat-conducting layer 4 is attached to the side of the hot air flow cavity plate 2 closest to the room. The front and rear edges of the heat spreader 3 near the interior are fixedly connected to the hot air flow cavity plate 2 by first countersunk bolts 8; The heat spreader 3 has a cover 5 attached to the front and back sides of the side closest to the room, and the heat conduction layer 4 is located inside the cover 5; The back panel 6 and the outer side of the cover 5 are fitted with a spliced ​​thermal insulation protective shell 9, the side of which is closer to the indoor surface is the heat-conducting surface.

[0024] Specifically, in this embodiment, the electric heating base layer 1 serves as the mounting base for the heating plate 16. The electric heating base layer 1 is equipped with a front and rear air circulation structure with the airflow direction facing forward. The spliced ​​heat-insulating protective shell 9 has only one side near the interior as the heat-conducting surface, while the other sides are insulated with heat-insulating materials to reduce heat loss and allow heat to be concentrated and transferred from the heat-conducting surface to the interior. Furthermore, the electric heating base layer 1 generates heat when energized. The heat is blocked by the spliced ​​insulation protective shell 9, reducing heat loss from other directions. The heat is efficiently transferred to the hot air flow cavity plate 2 by the front and rear air circulation structure, and then evenly distributed to the heat equalization layer 3 from the hot air flow cavity plate 2. Finally, it is evenly dissipated through the heat conduction layer 4 to the heat conduction surface of the spliced ​​insulation protective shell 9 on the side closest to the room. The back plate 6 and the cover 5 are made of materials with good thermal conductivity to avoid affecting heat conduction. The heat equalization layer 3 rapidly diffuses and transfers heat from the front end of the hot air flow cavity plate 2, which has a high temperature concentration, to the surrounding areas, making the temperature distribution uniform, significantly eliminating local overheating and underheating points, avoiding ineffective overheating, and achieving high thermal energy utilization and greater energy saving. It fundamentally eliminates the safety hazards caused by local overheating and extends the product's service life. More specifically, the electric heating base layer 1 is sandwiched between the hot air flow cavity plate 2 and the back plate 6. The front and rear ends of the hot air flow cavity plate 2 are detachably fixed to the edges of the back plate 6 for easy maintenance after disassembly. The heat spreader layer 3 is fixedly connected to the hot air flow cavity plate 2 by the first countersunk bolt 8 for easy maintenance after disassembly. The cover 5 is pasted on the heat spreader layer 3 and can be peeled off for easy maintenance after disassembly. The spliced ​​thermal insulation protective shell 9 adopts a spliced ​​structure for easy maintenance after disassembly. When disassembling the above structures, they are disassembled layer by layer from the outside to the inside for easy inspection and maintenance. Understandably, the device is suitable for use in situations where heat is unidirectionally dissipated into the room.

[0025] In some embodiments, the heat exchange layer 3 includes: The first heat-conducting plate 31a has a thermal conductivity greater than that of the hot air flow cavity plate 2; The first heat-conducting plate 31a is equipped with a radial strip heat-conducting structure 32a on the side away from the room. The radial strip-shaped heat-conducting structure 32a includes: The upper, middle, and lower sides of the front end of the first heat-conducting plate 31a, which is away from the indoor area, all serve as radiation sources. The radial strip groove 321a is radially arranged on the side of the first heat-conducting plate 31a away from the room, with the upper, middle and lower radiation sources as the center. A heat-conducting cable 322a is inserted into the radial strip groove 321a, and ear plates 323a inserted into the corresponding radial strip groove 321a are fixedly connected at both ends. The ear plate 323a is fixedly connected to the bottom surface of the corresponding radial strip groove 321a by bolts.

[0026] Specifically, in this embodiment, ear plates 323a are fixed at both ends of the heat conduction tape 322a, and the ear plates 323a are fixed to the bottom surface of the radial strip groove 321a by bolts; the heat conduction tape 322a and the ear plates 323a are both located in the corresponding radial strip groove 321a, no longer protruding from the side of the first heat conduction plate 31a away from the room, so that the side of the first heat conduction plate 31a away from the room is in contact with the side wall of the hot air flow cavity plate 2, and some heat is directly conducted through the first heat conduction plate 31a; Furthermore, the radially distributed heat-conducting tape 322a uses the upper, middle, and lower sides of the front end of the first heat-conducting plate 31a away from the room as radiation sources, and evenly dissipates the relatively concentrated heat from the hot air inlet end near the hot air flow cavity plate 2 to the entire first heat-conducting plate 31a, so as to conduct heat evenly. More specifically, ear plates 323a are fixed at both ends of the heat-conducting tape 322a. The ear plates 323a are fixed to the bottom surface of the radial strip groove 321a by bolts. The heat-conducting tape 322a, which is radially distributed on the upper, middle and lower sides, is fixed to the side of the first heat-conducting plate 31a away from the room, and it is convenient to disassemble and replace the heat-conducting tape 322a. It is understandable that the heat conduction tape 322a is an existing technology application. The heat conduction tape 322a is a functional material used for efficient heat conduction. The heat conduction tape 322a is mainly divided into three categories: copper heat conduction tape, double-arm low temperature heat conduction tape, and silicone thermal conductive tape. The heat conduction tape 322a in this embodiment is a copper heat conduction tape.

The airflow of fan 15 is directed forward.

[0028] Specifically in this embodiment, the rectangular frame 11 is made of aluminum plate, steel plate or fire-resistant plate, and serves as support and insulation. Furthermore, the rectangular frame 11 is sealed off on the side away from the interior, which allows the heat emitted by the heating plate 16 to be better conducted to the side closer to the interior. More specifically, the grid frame 12 is ventilated through the front and rear ventilation holes 13 and the upper and lower ventilation holes 14, and the fan 15 is used to blow air forward, with the airflow circulating through the front and rear ventilation holes 13 and the upper and lower ventilation holes 14. Understandably, the heating plate 16 has an insulating layer on the outside to ensure electrical safety, and the entire structure is sealed with vacuum or sealant to prevent moisture and oxidation.

[0029] In some embodiments, the hot air flow cavity plate 2 includes: The cavity panel 21 has strip-shaped rectangular covers 22 fixedly connected to its front and rear edges on the side away from the interior. The inner sides of the front and rear strip-shaped rectangular covers 22 are provided with air inlet and outlet windows 23, which are connected to the same side of the front and rear air circulation structure. Second countersunk bolts 24 are evenly inserted through the front and rear edges of the cavity plate 21 on the side closest to the interior, and their ends are screwed to the same edge of the back plate 6.

[0030] Specifically in this embodiment, the cavity plate 21 is made of a material with good thermal conductivity, the front and rear strip rectangular covers 22 cover the outer wall of the electric heating base layer 1 on the same side, the air inlet and outlet windows 23 are used for air inlet and outlet, and the front and rear ventilation holes 13 opened on the front and rear side walls of the rectangular frame 11 are used for air inlet and outlet. Furthermore, a sealing ring is provided between the second countersunk bolt 24 and the reserved through hole on the cavity plate 21 and the strip rectangular cover 22 to prevent wind leakage; More specifically, the heat is more concentrated on the air intake side of the cavity plate 21, and the heat is evenly distributed through the heat equalization layer 3.

[0031] In some embodiments, the thermally conductive layer 4 includes: A thermally conductive adhesive layer 42 is coated between the graphene film 41 and the heat-spreading layer 3 on the indoor side. The thermally conductive adhesive layer 42 is specifically a thermally conductive paste, which fills the microscopic gaps between the heat-spreading layer 3 and the graphene film 41 to reduce contact thermal resistance. The graphene film 41 is an existing technology application with high thermal conductivity.

[0032] Example 2, please refer to Figure 5 The difference between it and Example 1 is that; The heat exchange layer 3 includes: The second heat-conducting plate 31b has a thermal conductivity greater than that of the hot air flow cavity plate 2; The upper, middle, and lower sides of the front end of the second heat-conducting plate 31b, which is away from the indoor area, all serve as radiation sources. The heat-conducting rib 32b is radially welded to the side of the second heat-conducting plate 31b away from the room, with the upper, middle and lower radiation sources as the center.

[0033] Specifically in this embodiment, the heat-conducting rib 32b protrudes from the side of the second heat-conducting plate 31b away from the room and is directly attached to the side wall of the hot air flow cavity plate 2. Heat is conducted to the second heat-conducting plate 31b through the heat-conducting rib 32b. Furthermore, the radially distributed heat-conducting ribs 32b use the upper, middle, and lower sides of the front end of the second heat-conducting plate 31b away from the room as radiation sources, so as to evenly dissipate the relatively concentrated heat from the hot air inlet end near the hot air flow cavity plate 2 to the entire second heat-conducting plate 31b, and conduct heat evenly. It is understandable that the heat-conducting rib 32b is an application of existing technology. As a key structure to improve heat conduction efficiency and uniformity, the heat-conducting rib 32b is made of high-efficiency heat-conducting materials.

The third heat-conducting plate 31c is fixedly assembled from front to back with the first longitudinal fixing structure 32c, the second longitudinal fixing structure 33c and the third longitudinal fixing structure 34c on the side away from the indoor area. The first longitudinal fixing structure 32c, the second longitudinal fixing structure 33c and the third longitudinal fixing structure 34c are internally fixedly equipped with micro heat pipes 35c. The miniature heat pipe 35c has a radial distribution centered on the radiation sources on its upper, middle and lower sides; The first longitudinal fixing structure 32c, the second longitudinal fixing structure 33c, and the third longitudinal fixing structure 34c have the same structure. The third longitudinal fixing structure 34c includes: A longitudinal strip plate 34c1 has an arched cover 34c2 integrally formed on it corresponding to the position of the micro heat pipe 35c. An arched cover 34c2 is fitted onto the outside of the corresponding micro heat pipe 35c; The upper and lower edges of the arched cover 34c2 are both pierced by fixing bolts 34c3, the ends of which are screwed to the side of the third heat-conducting plate 31c away from the room.

[0035] Specifically, in this embodiment, an arched cover 34c2 is provided on the longitudinal strip plate 34c1 and is fitted onto the outside of the corresponding micro heat pipe 35c. The position of the arched cover 34c2 is set according to the radially distributed micro heat pipes 35c. The longitudinal strip plate 34c1 is fixed to the side of the third heat-conducting plate 31c away from the room by the fixing bolts 34c3 on the upper and lower edges of the arched cover 34c2, thereby fixing the radially distributed micro heat pipes on the upper, middle and lower sides. Furthermore, the radially distributed micro heat pipes 35c use the upper, middle, and lower sides of the front end of the third heat-conducting plate 31c away from the room as radiation sources, and evenly dissipate the relatively concentrated heat from the hot air inlet end near the hot air flow cavity plate 2 to the entire third heat-conducting plate 31c, so as to conduct heat evenly. More specifically, the micro heat pipes 35c, which are radially distributed on the upper, middle and lower sides, are fixed on the side of the third heat-conducting plate 31c away from the room, and the micro heat pipes 35c are easy to disassemble and replace.
