Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heater. Background Art

[0002] Existing counterbalanced heaters use heat pipes for heating. The heat generated by the heat pipes is transferred to the thermal conductive sheet and dissipated into the air through natural convection, thus achieving the desired heating effect. On the one hand, the heat pipes and thermal conductive sheet are connected by a crimping method, resulting in a large contact thermal resistance. The heat generated by the heat pipes cannot be dissipated through the thermal conductive sheet in a timely manner, resulting in a high internal temperature rise. This requires an increased number of heat sinks to dissipate the heat, which results in a longer overall unit size. Furthermore, the connecting ring area between the heat pipes and the thermal conductive sheet is small, resulting in poor heat dissipation and low overall thermal efficiency. Furthermore, due to the power limitations of the heat pipes, existing counterbalanced heaters generally have only two power levels, making them incapable of being freely adjusted according to user needs. This demonstrates the significant limitations of heat pipe heating and their poor thermal conductivity.

[0003] In order to solve the limitations of heat pipe heating, electromagnetic heating has been considered. However, the conventional practice of electromagnetic heating is to set an electromagnetic heating coil on one side of the heating element. However, although this method can solve the defects of the existing technology to a certain extent, it still has shortcomings. Utility Model Content

[0050] Existing counterbalanced heaters use heat pipes for heating. The heat generated by the heat pipes is transferred to the thermal conductive sheet and dissipated into the air through natural convection, thus achieving the desired heating effect. On the one hand, the heat pipes and thermal conductive sheet are connected by a crimping method, resulting in a large contact thermal resistance. The heat generated by the heat pipes cannot be dissipated through the thermal conductive sheet in a timely manner, resulting in a high internal temperature rise. This requires an increased number of heat sinks to dissipate the heat, which results in a longer overall unit size. Furthermore, the connecting ring area between the heat pipes and the thermal conductive sheet is small, resulting in poor heat dissipation and low overall thermal efficiency. Furthermore, due to the power limitations of the heat pipes, existing counterbalanced heaters generally have only two power levels, making them incapable of being freely adjusted according to user needs. This demonstrates the significant limitations of heat pipe heating and their poor thermal conductivity.

[0051] In order to solve the limitations of heat pipe heating, electromagnetic heating has been considered. However, the conventional practice of electromagnetic heating is to set an electromagnetic heating coil on one side of the heating element. However, although this method can solve the defects of the existing technology to a certain extent, it still has shortcomings.

[0052] See also Figures 1 to 2 The utility model provides a heater 100, including a heating element 2 and an electromagnetic heating structure; the heating element 2 has an adjacent first side and a second side; the electromagnetic heating structure includes a first electromagnetic heating coil assembly 31 and a second electromagnetic heating coil assembly 32, the first electromagnetic heating coil assembly 31 is used to be set corresponding to the first side of the heating element 2, and the second electromagnetic heating coil assembly 32 is used to be set corresponding to the second side of the heating element 2, so as to electromagnetically heat the heating element 2 respectively.

[0053] In the heater 100 provided by the present invention, the electromagnetic heating structure includes the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32. When heating is required, alternating current is passed through the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32, and a high-frequency converted magnetic field is generated on the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32. The first side and the second side of the heating element 2 are respectively arranged corresponding to the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32. Therefore, the first side and the second side of the heating element 2 generate a high-frequency changing induced magnetic field due to cutting the magnetic flux lines, and eddy currents are generated on the metal surface. Due to the Joule heating effect, the bottom of the heating element heats the metal itself and generates heat. The heat generated on the heating element 2 is exerted on the surrounding The air is heated, wherein, since the heating element 2 is heated by the electromagnetic heating structure, there is no electrical connection between the heating element 2 and the electromagnetic heating structure, and the safety is greatly improved; as long as the position where the coil magnetic field exists belongs to the heating area, compared with the ring connection of the heat pipe, the contact thermal resistance is greatly reduced, and the heating efficiency and heat transfer efficiency of the whole machine are also significantly improved; the thermal conductivity of the heating element 2 is effectively improved. At the same time, since the electromagnetic heating structure includes the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32, heat can be generated at different positions corresponding to the heating element 2, and the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 correspond to different sides respectively, to achieve three-dimensional heating, so that the heating area of the heating element 2 is larger, the heat is more uniform, and the heating effect is better.

[0054] In addition, the electromagnetic heating structure is used to generate heat on the heating element 2 by inducing eddy currents, wherein the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 do not need to be kept in the same space as the heating element 2, as long as the heating element 2 is within the magnetic field range of the electromagnetic heating structure.

[0055] In one embodiment, the heater further comprises a housing 1, wherein the housing 1 is provided with a through hole 11 so that air can be exchanged with air outside the housing 1 through the through hole 11, and the heating element 2 is provided in the housing 1. The heating element 2 is built into the housing 1, and the housing 1 is provided with the through hole 11 so that air outside the housing 1 can be exchanged with air inside the housing 1 through the through hole 11. The air entering the housing 1 is heated by the heating element 2 and then flows out of the housing 1, that is, the heat generated by the heating element 2 is taken out of the housing 1, thereby meeting the heating function requirements of the heater 100.

[0056] Furthermore, the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 are disposed within the housing 1. Thus, the housing 1 protects the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32, preventing accidental damage to the electromagnetic heating structure. Furthermore, during power-on, current leakage from the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 can be avoided, potentially causing electric shock to the user.

[0057] In addition, the plurality of through holes 11 are provided, and the plurality of through holes 11 include an air inlet through hole 11a provided at the lower end of the housing 1, and an air outlet through hole 11b provided at the upper end of the housing 1. In the present application, the air inlet through hole 11a and the air outlet through hole 11b facilitate the housing 1 to achieve air intake at the lower end and air outlet at the upper end. When the heating element 2 generates heat, the hot air rises and rises out of the air outlet through hole 11b, and the cold air below the housing 1 is sucked in through the air inlet through hole 11a, completing the rapid exchange of air within the housing 1 and improving the heat output effect of the heater 100.

[0058] Furthermore, the air outlet holes 11b are provided at the top of the housing 1, and the air inlet holes 11a are provided at the bottom of the housing 1. In the present application, the air outlet holes 11b and the air inlet holes 11a are located at the top and bottom of the housing 1, respectively, so that air can be directly drawn in from the bottom and then rise out from the top. During the air exchange process, there will be no airflow obstruction, thereby improving the temperature exchange rate between the air and the housing 1.

[0059] In addition, there are multiple options for the first side and the second side, as long as the electromagnetic heating structure can heat the adjacent two sides of the heating element 2 at the same time.

[0060] In this application, please see Figures 3 and 4 The first side and the second side are arranged adjacent to each other, and the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 heat the adjacent two sides respectively, wherein the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 are arranged in an L shape to facilitate heating the adjacent two sides.

[0061] For details, please refer to Figures 5 and 6, the first side is the lower side of the heating element 2, and the second side is one side of the heating element 2 in the horizontal direction. In the present application, the electromagnetic heating structure heats the lower side and the horizontal side of the heating element 2 at the same time, so that the heating element 2 is surrounded by the electromagnetic heating structure on multiple sides. The heating element 2 can achieve electromagnetic induction heating on multiple sides at the same time, realizing three-dimensional heating, making the heating area of the heating element 2 larger and the heating more uniform, thereby improving the heating effect of the heating element 2. Heating from the bottom and horizontally allows the heat to naturally converge and rise, and will not be transferred to the electromagnetic heating structure.

[0062] It should be noted that, in this embodiment, the heating element 2 and / or the first electromagnetic heating coil assembly 31 are provided with air holes extending in the vertical direction. In this embodiment, the heating element 2 generates heat, and the air flow within the entire housing 1 rises from the bottom to the top. To facilitate the flow of air, the air holes can be provided in the heating element 2 and the first electromagnetic heating coil assembly 31 to ensure smooth airflow.

[0063] In this embodiment, the air holes are provided on the heating element 2 and the first electromagnetic heating coil assembly 31. The air holes on the heating element 2 not only facilitate the flow of air, but also improve the heat exchange rate between the heating element 2 and the air; the air holes on the first electromagnetic heating coil assembly 31 not only facilitate the flow of air, but also improve the heat dissipation of the first electromagnetic heating coil assembly 31.

[0064] See also Figures 7 and 8 Since the first side is the lower side of the heating element 2 and the second side is one side of the heating element 2 in the horizontal direction, the electromagnetic heating structure heats the lower side and the horizontal side at the same time, so that the electromagnetic heating structure is L-shaped, and the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 realize three-dimensional heating of the heating element 2.

[0065] At the same time, since the first side is the lower side of the heating element 2, the cold air entering through the air inlet hole 11a below can flow through the electromagnetic heating structure, thereby taking away the heat generated by the electromagnetic heating structure.

[0066] Specifically, the housing 1 is elongated and extends laterally; the first side is the lower side of the heating element 2, and the second side 2 is the side of the heating element 2 in the transverse direction. In the present application, the heating element 2 is also surrounded by the side surrounds, so that the heating element 2 can generate heat at the bottom and one side in the transverse direction at the same time, thereby improving the heating effect. The second electromagnetic heating coil 32 is provided on one side in the transverse direction, so that the housing 1 can be made thinner, avoiding the housing 1 being too wide, and can be more suitable for the environment of household skirting boards, and can be placed between the gaps of the clamps.

[0067] In one embodiment, the heating element 2 has two opposing second sides; the electromagnetic heating structure includes two second electromagnetic heating coil assemblies 32, which are arranged corresponding to the two second sides of the heating element 2. In the present application, the two second electromagnetic heating coil assemblies 32 heat the two opposing sides of the heating element 2, thereby increasing the range of the magnetic field on the second electromagnetic heating coil assemblies 32, allowing the magnetic fields on both sides to act simultaneously, thereby increasing the coverage of the magnetic field on the heating element 2, increasing the heat generation area, and improving the heat generation effect.

[0068] Furthermore, the ends of the two second electromagnetic heating coil assemblies 32 are connected to each other through a connecting portion, so that the two second electromagnetic heating coil assemblies 32 are arranged as one body, so as to facilitate the installation of the two second electromagnetic heating coil assemblies 32, and the two second electromagnetic heating coil assemblies 32 and the connecting portion are arranged in a U shape.

In this application, the electromagnetic coil is formed by winding the coil on the bracket, so as to generate a magnetic field through electromagnetic induction, thereby generating heat on the heating element 2.

[0070] In one embodiment, the first bracket and the second bracket of the first electromagnetic heating coil assembly 31 and the second electromagnetic heating coil assembly 32 are integrally arranged to form an integrated bracket.

[0072] In addition, in one embodiment, the first electromagnetic heating coil assembly 31 includes multiple first coils, and the multiple first coils are used to electromagnetically heat the heating element 2; in the present application, the multiple first coils can be used to achieve separate control of different positions of the first electromagnetic heating coil assembly 31. At the same time, since multiple first coils are provided, maintenance and replacement can be facilitated. When problems arise, there is no need to disassemble all the coils, and multiple first coils can be used to simultaneously control the heating of different positions of the heating element 2.

The heat-insulating plate 4 also shields the magnetic field generated by the coil.

[0077] Furthermore, the plurality of through holes 11 are provided, including an air inlet through hole 11a provided at the lower end of the housing, and an air outlet through hole 11b provided at the upper end of the housing 1; the heat insulation board 4 is provided corresponding to the side of the housing 1, so as to enclose the side of the housing 1 together to form the heat insulation cavity. In the present application, the heat insulation cavity is located between the side of the housing 1 and the heat insulation board 4, isolating the electronic control component 5 from the heating element 2. The heat insulation cavity can be formed within the housing 1 together with the side simply by dividing the housing 1, resulting in a simple structure and low cost.

[0078] Furthermore, the heat insulation board 4 is correspondingly provided on the inner side of each side portion of the housing 1, so that the heat insulation cavity is formed on the surrounding side of the heating element 2. In the present application, the heat insulation cavity is formed on the surrounding side of the heating element 2, so that different electronic control components 5 can be arranged in different heat insulation cavities to perform different functional controls, facilitate space arrangement, and facilitate subsequent maintenance processes.

In the present application, the fan is used to cool the electronic control component 5 in the insulation cavity to prevent the electronic control component 5 from overheating.

[0080] Among them, the air outlet can be set at the top of the shell 1 to quickly remove the temperature in the insulation cavity, or it can be set on the insulation board 4 to transfer the heat on the electronic control component 5 to the heating element 2, thereby improving the heat utilization rate of the heater 100 and avoiding heat waste.

[0081] Furthermore, the second electromagnetic heating coil assembly 32 is disposed on a side of the housing 1; at least a portion of the side of the housing 1 is configured as a metal plate capable of being electromagnetically heated by the electromagnetic heating coil assembly.
