Description

Technical Field

[0001] This utility model belongs to the field of automotive pipeline heating, and more specifically, it relates to a heating component. This utility model also relates to an electric heater that uses the above-mentioned heating component. Background Technology

[0002] The car engine is the device that provides power to a car; it is the heart of the vehicle and determines its power, economy, stability, and environmental performance. Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid engines, among others.

[0003] Both common gasoline and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement and output power. Gasoline engines have high speed, small mass, low noise, easy starting, and low manufacturing cost; diesel engines have a large compression ratio, high thermal efficiency, and better fuel economy and emissions performance than gasoline engines.

[0004] Maintaining unobstructed fuel lines is crucial for engine and vehicle operation. Especially in cold regions, heaters are necessary to prevent fuel from becoming viscous and to maintain its fluidity, which could damage the engine. However, under harsh operating conditions during normal engine operation, existing heaters are prone to poor contact, leading to inadequate heating performance. This, in turn, obstructs fuel flow, impacting engine performance and necessitates improvement. Utility Model Content

[0005] The purpose of this invention is to provide a heating component to solve the technical problem of poor contact in existing engine pipeline heating devices.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heating assembly is provided, including a power supply unit and a heating unit. The power supply unit includes two electrode plates, and the heating unit includes a heating shell and a heating plate. The two electrode plates are respectively located on both sides of the surface of the heating plate, and both electrode plates are located between the heating plate and the inner wall of the heating shell. An elastic support member is provided on the electrode plate, and the elastic support member can form an elastic connection between the electrode plate and the heating plate and / or the heating shell.

[0007] In one possible implementation, the heating element further includes an insulating heat conductor disposed between the electrode sheet and the heating housing.

[0008] In one possible implementation, the insulating thermal conductor is configured as a polyimide film, thermally conductive rubber, or ceramic plate.

[0009] In one possible implementation, the power supply unit further includes a wire harness and wires respectively connected to the two electrode plates, both of which are located inside the wire harness, and the wire harness is sealed to the heating housing.

[0010] In one possible implementation, the power supply unit further includes a sealing material disposed between the outer periphery of the heating housing and the wire harness sleeve, and the sealing material is capable of forming a sealed connection between the heating housing and the wire harness sleeve.

[0011] In one possible implementation, the insulating heat conductor is packaged in a bag, and both the electrode sheet and the heating plate are located within the insulating heat conductor.

[0012] In one possible implementation, the elastic support includes a plurality of elastic protrusions, each of which is evenly distributed on any side of the electrode sheet.

[0013] In one possible implementation, the elastic protrusion is configured as an elastic boss or a spring.

[0014] In one possible implementation, a connecting plate is integrally connected to the end of the electrode sheet, the connecting plate being clamped to the end of the wire and electrically connected to the wire.

[0015] Compared with the prior art, the beneficial effects of the heating component provided by this utility model are as follows: during the pressing process of the heating shell, the heating shell clamps the internal electrode sheet and heating plate. As the electrode sheet gradually adheres to the heating plate and heating shell, the electrode sheet can elastically position the heating plate through the elastic deformation of the elastic support member, or form elastic support for the electrode sheet and heating plate through the elastic deformation of the elastic support member. In this way, the electrical connection between the heating plate and the electrode sheet can remain stable in the working environment with frequent vibration, thereby solving the technical problem that the electrical connection between the internal structures of the existing heating equipment will be broken in the working conditions with frequent vibration.

[0016] Another objective of this invention is to provide an electric heater, including the heating components described above.

[0017] Compared with the prior art, the electric heater of this utility model has all the advantages of the above-mentioned heating components, which will not be elaborated here. Moreover, the electric heater of this utility model can adapt to the harsh working conditions of frequent vibration in motor vehicles or special operation vehicles during use. It maintains a stable internal structure under harsh working conditions, without short circuits or interruptions, thereby ensuring the stable operation of motor vehicles or special operation vehicles.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0029] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] Overall, please refer to the following: Figures 1 to 4 This utility model mainly solves the technical problem of poor internal structural contact in existing heaters under vibration conditions by setting an elastic structure on the electrode plate 21 to support the movable gap between the electrode plate 21, the heating plate 11 and the heating shell 12.

[0031] Based on the above design concept, in a more specific embodiment, the heating assembly includes a power supply unit 2 and a heating unit 1. The power supply unit 2 includes two electrode plates 21, and the heating unit 1 includes a heating shell 12 and a heating plate 11. The two electrode plates 21 are located on both sides of the heating plate 11, and both electrode plates 21 are located between the heating plate 11 and the inner wall of the heating shell 12. The electrode plates 21 are provided with elastic support members, which can form an elastic connection between the electrode plates 21 and the heating plate 11 and / or the heating shell 12.

[0032] In the specific implementation of this embodiment, the elastic support can be provided on the inner or outer side of the electrode sheet 21, or on both the inner and outer sides of the electrode sheet 21. The specific setting method can be flexibly set according to the material of the outer shell or the internal space, which will not be elaborated here.

[0033] Compared with the prior art, the beneficial effect of the heating component in this embodiment is that, during the pressing process of the heating shell 12, the heating shell 12 clamps the internal electrode sheet 21 and the heating plate 11. As the electrode sheet 21 gradually presses against the heating plate 11 and the heating shell 12, the electrode sheet 21 can elastically position the heating plate 11 through the elastic deformation of the elastic support member, or form elastic support for the electrode sheet 21 and the heating plate 11 through the elastic deformation of the elastic support member. In this way, the electrical connection between the heating plate 11 and the electrode sheet 21 can remain stable in the working environment with frequent vibration, thereby solving the technical problem that the electrical connection between the internal structures of the existing heating equipment will be broken in the working conditions with frequent vibration. Moreover, the arrangement of the various structures in the heating shell 12 in this embodiment is more compact, which is conducive to improving the internal integration of the heating component in this embodiment and reducing space occupation.

[0034] Considering that the heating shell 12 is generally made of metal, in order to prevent leakage, based on the above embodiments, in one possible implementation, an insulating heat conductor 25 is provided between the electrode sheet 21 and the heating shell 12, thereby forming insulation between the electrode sheet 21 and the heating shell 12 through the insulating heat conductor 25, preventing leakage of the heating shell 12.

[0035] Based on the same embodiment, in a further possible implementation, the insulating heat conductor is set as a polyimide film, thermally conductive rubber, or ceramic plate. Among them, the polyimide film is preferred due to its high temperature resistance, good flexibility, and high insulation. Of course, considering factors such as cost, using thermally conductive rubber or ceramic plate as the insulating heat conductor is also an optional implementation.

[0036] In addition to the above-mentioned feasible implementation methods, the insulating heat conductor 25 can be configured as a bag. After the electrode sheet 21 and the heating plate 11 are assembled, they are installed inside the insulating heat conductor 25. Then, the wrapped electrode sheet 21 and the heating plate 11 are placed inside the heating shell 12. In this way, by pressing the heating shell 12, the electrode sheet 21 and the heating plate 11 can be stably set inside the heating shell 12 to prevent loosening inside.

[0037] In some feasible embodiments, the power supply unit 2 also includes a wire harness 23 and wires 22 connected to the two electrode plates 21 respectively, so as to perform photoelectric stimulation on the two electrode plates 21. Both wires 22 are located inside the wire harness 23. The wire harness 23 is sealed to the heating shell, forming a seal between the heating shell and the internal structure, preventing external moisture or foreign objects from entering the interior of the heating shell, thereby improving the stability of the heating component in the present invention during operation.

[0038] To prevent gaps from forming between the cable tie 23 and the heating housing 12, a more preferred embodiment is proposed. Specifically, the power supply unit 2 in this embodiment further includes a sealing material 24, which is disposed between the outer periphery of the heating housing 12 and the cable tie 23, and the sealing material 24 can form a sealed connection between the heating housing 12 and the cable tie 23.

[0039] Optionally, the sealing material 24 can be a rubber sleeve, which is first fitted around the outer periphery of the wire harness sleeve 23, thereby forming a sealed connection between the heating housing 12 and the wire harness sleeve 23 during the pressing of the heating housing 12. The sealing material 24 can also be a sealant, or the rubber can be filled between the wire harness sleeve 23 and the heating housing 12 by vulcanization molding. The process is carried out by pressing the heating housing 12 first and then filling the sealing material 24, which makes the processing more convenient and reduces the number of parts required for the entire heating assembly.

[0040] In some feasible embodiments, the elastic support includes a plurality of elastic protrusions 211, each elastic protrusion 211 being evenly distributed on any side of the electrode sheet 21. The even distribution of the elastic protrusions 211 forms a stable elastic support for the internal electrode sheet 21, heating plate 11, and insulating heat conductor, preventing poor contact and other problems from occurring in the electrode sheet 21 or heating plate 11 during the vibration of the heating shell 12, thereby improving the reliability and stability of the heating component in this utility model. Based on this embodiment, in a more preferred embodiment, the elastic protrusions 211 are configured as elastic bosses or spring sheets to facilitate the processing of the above-mentioned elastic structure on the electrode sheet 21.

[0041] In some feasible implementations, a connecting plate 212 is integrally connected to the end of the electrode plate 21. The connecting plate 212 is clamped to the end of the wire 22 and electrically connected to the wire 22 to form a stable connection between the wire 22 and the electrode plate 21, preventing the connection between the electrode plate 21 and the wire 22 from loosening during vibration.

[0042] In summary, compared with the prior art, the heating assembly provided by this utility model, during the pressing process of the heating shell 12, the metal heating shell 12 gradually deforms and tightens the internal electrode plate 21 and heating plate 11. As the electrode plate 21 gradually presses against the heating plate 11 and the heating shell 12, the electrode plate 21 can elastically position the heating plate 11 through the elastic deformation of the elastic support member, and form elastic support for the electrode plate 21 and the heating plate 11 through the elastic deformation of the elastic support member (elastic boss or spring). Thus, in working environments with frequent vibrations, the heating assembly of this utility model ensures that the heating plate 11 and the heating plate 11 are elastically supported. The electrical connection between the electrode plates 21 can remain stable, thus solving the technical problem that the electrical connection between the internal structures of existing heating equipment will be broken under frequent vibration conditions. Moreover, this utility model can also assemble the electrode plates 21 and the heating plate 11 together and put them into a polyimide insulating heat-conducting bag. After the above three are assembled, they are placed in the heating shell 12. A seal is formed between the heat dissipation shell port and the wire bundle sleeve 23 of the wire 22 by pressing. This makes the interconnection and relative position relationship of the internal structure of the entire heating assembly more stable, which helps to solve the problem that the internal structure of existing heating assemblies is prone to breakage due to vibration and other reasons.

[0043] Based on the same inventive concept, this utility model also proposes an electric heater, which includes the heating component mentioned above.

[0044] The electric heater of this utility model has all the advantages of the above-mentioned heating components, which will not be repeated here. Moreover, the electric heater of this utility model can adapt to the harsh working conditions of frequent vibration in motor vehicles or special operation vehicles during use. It maintains a stable internal structure under harsh working conditions, without short circuits or interruptions, thereby ensuring the stable operation of motor vehicles or special operation vehicles.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
