The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present embodiment discloses a specific structure of a thermal conductive agent-based electric heating device, which includes an electric heat source 1, a thermal conductive filling layer 2, a thermal conductive insulating protective layer 3, and a device housing 4, which are sequentially sleeved from inside to outside, and a thermal conductive agent is filled between the thermal conductive insulating protective layer 3 and the device housing 4.

In other words, the heat conductive filling layer 2 is sleeved outside the electric heat source 1, and the heat conductive insulating protection layer 3 is sleeved outside the heat conductive filling layer 2. The heat conducting agent (i.e. the first heat conducting agent a) filled between the heat conducting insulating protective layer 3 and the device housing 4 forms a heat conducting layer for absorbing and conducting the heat transferred from the heat conducting insulating protective layer 3. When the heat conduction agent works, the electric heat source 1 converts electric energy into heat energy, and the heat energy is sequentially conducted into the first heat conduction agent a through the heat conduction filling layer 2 and the heat conduction insulation protection layer 3.

The device case 4 is provided with a heat pipe 5. One end of the heat pipe 5 penetrates through the outer wall of the device housing 4 and then is immersed in the heat conducting agent, and the other end extends to the outside of the device housing 4, the heat pipe 5 is kept closed, and the inside is filled with the heat conducting agent (i.e. the second heat conducting agent b). Correspondingly, the heat energy that holds in the first heat-conducting agent a conducts in heat pipe 5, conducts to the one end that heat pipe 5 kept away from heat conduction insulating protective layer 3 through the flow of the second heat-conducting agent b in heat pipe 5, transmits the liquid of treating the heating evaporation by this end then, accomplishes whole heat-conduction process.

As mentioned before, the electric heat source 1 is used for converting electric energy into heat energy. The electric heat source 1 is implemented in various forms, and exemplarily, the electric heat source 1 may be a resistance heating rod or a dry-fire heating rod.

The electric heating source 1 can be powered by a power supply battery arranged in the electric heating device, and can also be powered by an external power supply independent of the electric heating device. Exemplarily, one end of the device housing 4 is provided with an electrical connector 6, one end of the electrical connector 6 is electrically connected to the electric heating source 1, and the other end is used for connecting an external power source (e.g., a commercial power network). Wherein, the electric connector 6 is also positioned at the inner side of the heat-conducting insulating protective layer 3, so that the electric connector 6 is not contacted with the electric heating device and the liquid of the electric boiler, and the electric safety is ensured.

The heat conducting filling layer 2 is a good heat conductor, and exemplarily, the heat conducting filling layer 2 is filled with a vacuum-free heat conducting agent or a heat conducting filling glue. The vacuum-free heat conducting agent is a vacuum-free heat conducting agent, generally a heat conducting liquid, and is applied without vacuum, such as vacuum-free superconducting liquid.

The heat-conducting insulating protective layer 3 has two main performances of heat conduction and electric insulation, and ensures good heat conduction capability and insulating safety. The thermally conductive, insulating, and protective layer 3 is illustratively made of a thermally conductive ceramic, such as typically polycrystalline diamond ceramic, silicon carbide ceramic, or the like.

Exemplarily, the first heat-conducting agent a is a vacuum-free heat-conducting agent with a boiling point of 120 ℃ and a freezing point of-45 ℃; alternatively, the first thermal conductive agent a may be a vacuum thermal conductive agent with a start-up temperature of 30 ℃. The above-mentioned setting conditions make the heat conduction efficiency of the first heat-conducting agent a more excellent.

As described above, the heat conductive pipe 5 is used to transfer the heat energy in the first heat conductive agent a to the evaporation end, and the liquid is evaporated to realize the boiler function. Exemplarily, the heat conductive pipe 5 has a spiral configuration or a closed loop configuration. It can be understood that the inside of the heat conducting pipe 5 also forms a flow channel with a corresponding shape structure for the second heat conducting agent b to flow and conduct heat.

Exemplarily, the second thermal conductive agent b is a vacuum thermal conductive agent with a start-up temperature of 30 ℃. The volume of the second heat conducting agent b is 10-30 ml. The above-mentioned setting conditions make the heat transfer efficiency of the second heat-conducting agent b more excellent.

Exemplarily, the electric heating source 1, the heat-conducting filling layer 2, the heat-conducting insulating protective layer 3 and the device shell 4 have a coaxial distribution relationship, so that the electric heating device is easy to manufacture and achieve and has good heating efficiency.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
