[0029] Example 1

[0030] Please refer to Figure 1-Figure 4 The utility model provides a heating device, and takes its use for heating water as an example to explain the principle. The utility model comprises a main body 1, wherein the main body 1 comprises a carrier 11, an insulating layer 12, a heat-conducting layer 13 and an electrode 14. The carrier 11 is used for the circulation of liquid and the conduction of receiving heat. The insulating layer 12 is used to separate the carrier 11 from the heat-conducting layer 13. The heat-conducting layer 13 is used to conduct heat to the insulating layer 12 and the carrier 11 at the same time. The electrode 14 is used to conduct power to the heat-conducting layer 13 to realize electrical heating of the heat-conducting layer 13. The insulating layer 12 is arranged on the outer surface of the carrier 11, and the heat-conducting layer 13 is arranged on the outer surface of the insulating layer 12. The electrode 14 is electrically connected to the heat-conducting layer 13. The liquid only flows through the carrier 11 and does not contact the heat-conducting layer 13. In addition, the insulating layer 12 separates the carrier 11 and the heat-conducting layer 13, which well solves the problem of the liquid being charged after being heated, and is safer to use. In addition, the insulating layer 12 is used to wrap the carrier 11, which can extend the life of the heating device.

[0031] Specifically, the heat conducting layer 13 is a nano-metal layer, the insulating layer 12 is a quartz glass layer, and the carrier 11 is a stainless steel tube.

[0032] It is worth mentioning that nanometals have a larger specific surface area, which means that nanometals of the same mass have a larger surface area than metals of traditional size, and are therefore more likely to exchange heat with the surrounding environment; secondly, due to the nanoscale effect, electron transmission between nanometal particles is faster, resulting in higher electrical conductivity and lower resistivity, thereby improving heating efficiency; finally, nanometals may also exhibit quantum scale effects, such as localized surface plasmon resonance, which can further improve their ability to absorb and convert light energy, thereby enhancing heating efficiency.

[0033] The reasons for designing the insulating layer 12 to wrap the carrier 11 are: first, since this product needs to heat the liquid instantly, its power can reach 3KW-4KW, and the quartz glass tube has a very high thermal expansion coefficient. If the temperature changes rapidly, the tube wall will be subjected to greater stress, which will make it easy to break; second, since the nanometal layer has a certain lifespan, when the nanometal layer reaches its limit, the nanometal layer will break. At this time, the insulating layer 12 plays an isolating role to prevent the power supply from directly contacting the carrier 11; third, the thermal conductivity coefficient of stainless steel is higher than that of quartz glass, and it can transfer heat to the liquid more effectively; fourth, quartz glass has good thermal conductivity and a more uniform temperature distribution. The thermal conductivity of stainless steel tubes is poor, and there will be local high temperatures. Quartz glass can make the temperature distribution on the stainless steel tube uniform and reduce the precipitation of scale.

[0034] In addition, the nano-metal layer includes nano-titanium, nano-nickel and nano-tungsten, or one of nano-titanium, nano-nickel and nano-tungsten, or any two of nano-titanium, nano-nickel and nano-tungsten.

[0035] Furthermore, when the electrode 14 is a copper electrode 141 and a silver electrode 142, the silver electrode 142 is located at the bottom of the copper electrode 141. Silver is an excellent conductive metal with very high electrical conductivity and thermal conductivity. Therefore, the use of silver in the electrode material can effectively transmit electrical energy and thermal energy, and improve the heating efficiency and performance. Copper is also an excellent conductive metal and thermal conductive metal. Although its electrical conductivity and thermal conductivity are slightly inferior to silver, it still has high electrical conductivity and thermal conductivity, and the cost is relatively low. The use of the silver electrode 142 and the copper electrode 141 in superposition can effectively improve the heat transfer efficiency and performance of the heating device, and also has a relative advantage in cost control.

[0036] Reference Figure 2Three electrodes 14 and two thermostats 2 are arranged on the outer surface of the heat-conducting layer 13, one of the thermostats 2 is electrically connected to one of the electrodes 14 by a power line, and the other thermostat 2 is also connected to the other two electrodes 14 by a power line; the thermostat 2 automatically controls the power conduction of the heating layer according to the temperature change of the working environment, and a temperature sensor 4 is arranged therein for automatic sampling and monitoring of the ambient temperature. The detected temperature value is converted into an electrical signal by the temperature sensor 4, and then transmitted to the control circuit for processing and judgment. The control circuit processes and judges the electrical signal transmitted by the temperature sensor 4, and controls the power conduction of the heating layer by controlling the actuator according to the difference between the set temperature value and the actually detected temperature value.

[0037] Furthermore, it also includes a connection nozzle 3 and a temperature sensor 4, the connection nozzle 3 is arranged at both ends of the main body 1, and the temperature sensor 4 is arranged on the connection nozzle 3. When the heating device is installed on a water pipeline, it needs to connect the water inlet pipe and the water outlet pipe, and the connection nozzle 3 is arranged to make the connection more convenient. The temperature sensor 4 used is an NTC temperature sensor, which can monitor the liquid temperature of the water inlet pipe and the liquid temperature of the water outlet pipe through the temperature sensor 4, and receive accurate temperature information.

[0038] Furthermore, a sealing member 5 is provided at the connection between the connection nozzle 3 and the main body 1 , and the sealing member 5 is a silicone sleeve, so that the liquid flowing through the connection nozzle 3 flows into the carrier 11 without liquid leakage in the process.

[0039] Furthermore, it also includes a shell 6, the shell 6 half surrounds the main body 1, and the shell 6 is made of aluminum alloy. Figure 2 The housing 6 exposes one side of the heat-conducting layer 13, and the electrode 14 and the temperature controller 2 are both arranged on the exposed side.

[0040] Furthermore, it also includes two mounting supports 7, which are connected to the connecting nozzle 3, specifically arranged on the end surface of the connecting nozzle 3, and the mounting supports 7 are provided with holes for mounting screws, and the heating device can be fixed in position through the mounting supports 7.

[0041] Example 2

[0042] The difference from the first embodiment is that the carrier 11 is omitted and the insulating layer 12 is directly used as the carrier 11 .

[0043] Example 3

[0044] The difference from the first embodiment is that the electrode 14 only uses a copper electrode 141 or a silver electrode 142 .

[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
