[0002] In industrial production, gas electric heaters play a crucial role and are widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry, and institutions of higher learning. However, traditional gas electric heaters often face technical problems such as high operation costs, limited heating efficiency, and low energy conversion efficiency during operation.

[0003] Traditional gas electric heaters often do not fully consider the layout of heating elements and heat dissipation effects in design, resulting in uneven heat distribution, which affects the heating effect and product quality. In addition, due to the unreasonable material and structure design of heating elements, burnout is likely to occur, which not only increases the maintenance cost but also reduces the service life. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel gas electric heater to solve the technical problem of how to balance reducing operation costs while improving heating efficiency in the existing technology.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0023] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0024] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0026] As Figures 1 to 2 shown, a novel gas electric heater provided by an embodiment of the present application includes:

[0027] A cylinder body 1, with an inlet 11 and an outlet 12 respectively provided at both ends of the cylinder body 1;

[0028] A heating assembly 2, and the heating assembly 2 is arranged in the cylinder body 1 through a connecting member.

[0029] Compared with the prior art, the novel gas electric heater provided by the present utility model can effectively reduce the operation cost and maximize the heating power within a limited space, that is, by arranging the heating assembly 2 in the cylinder body 1, the surface of the heating assembly 2 can be made to contact the gas to be heated as much as possible; in addition, the heating assembly 2 of the present utility model adopts electric heating technology, can operate without 24-hour boiler steam supply, and the cost of electric energy is relatively low.

[0030] In another embodiment of the present application, as Figure 1 and Figure 2 shown, the heating assembly 2 includes a heating rod 21 and spiral fins 22; the spiral fins 22 are arranged outside the heating rod 21. The heating rod 21 is the main heat-generating component, which converts electrical energy or other energy into heat energy to generate heat. The spiral fins 22 are cleverly arranged outside the heating rod 21. The function of the spiral fins 22 is to increase the contact area between the heating rod 21 and the surrounding environment, so as to more effectively dissipate heat. The design of the spiral fins 22 not only further increases the heat dissipation area, but also, due to its spiral shape, can guide the heat flow direction to a certain extent, making the heat distribution more uniform. This heating assembly combining the heating rod 21 and the spiral fins 22 can achieve more uniform heat distribution while maintaining efficient heating.

[0031] In another embodiment of the present application, as Figure 1 and Figure 2 shown, the heating rod 21 includes a PTC material resistor 211, conductive electrodes 212, an insulating layer, and a base tube 213; conductive electrodes 212 are provided at both ends of the PTC material resistor 211; an insulating layer and a base tube 213 are sequentially provided outside the PTC material resistor 211. PTC, that is, Positive Temperature Coefficient, is a material with a positive temperature coefficient. The characteristic of this material is that the resistivity increases with the increase of temperature. Therefore, during the heating process, when the temperature rises to a certain level, the resistivity of the PTC material resistor 211 will also increase accordingly, thereby restricting the passage of current and playing a role in automatic temperature control. This characteristic makes the PTC material resistor 211 very suitable for heating devices that require precise temperature control.

[0032] The conductive electrodes 212 are arranged at both ends of the PTC material resistor 211. Their main function is to connect the PTC material resistor to an external power source, enabling current to pass smoothly, thereby realizing the heating function. The conductive electrodes 212 are usually made of materials with good electrical conductivity to ensure the stable transmission of current.

[0033] To ensure the safety and stability of the heating rod 21, an insulating layer and a base tube 213 are sequentially provided outside the PTC material resistor 211. The insulating layer mainly plays the role of electrical insulation, preventing safety hazards such as current leakage or short circuits. The base tube 213 serves as the support and protection layer of the heating rod 21 and is usually made of materials with high temperature resistance and corrosion resistance to cope with problems such as high temperature or chemical corrosion that may occur during the heating process.

[0034] In another embodiment of the present application, as Figure 1 and Figure 2As shown, the spiral fin 22 is connected to the base tube 213 of the heating rod 21 by laser welding. As an advanced connection technology, laser welding has the advantages of fast welding speed, small heat-affected zone, high weld strength, good airtightness and sealing performance. Through laser welding, the connection between the spiral fin 22 and the base tube 213 is not only firm and reliable, but also can effectively resist the thermal stress generated by temperature changes, ensuring the stability and durability of the heating component under long-term and high-load working conditions. This connection method also helps to improve the overall efficiency of the heating component. Due to the small heat-affected zone of laser welding, the material properties of the base tube 213 and the spiral fin 22 are less affected, and their good thermal conductivity can be maintained. At the same time, the heat generated during the welding process can be quickly dissipated, avoiding thermal damage to other parts of the heating component. In addition, the weld quality of laser welding is high and the appearance is beautiful, meeting the aesthetic requirements of industrial products. This not only improves the overall quality of the heating component, but also provides strong support for its promotion in the market.

[0035] In another embodiment of the present application, as Figure 1 and Figure 2 shown, a heat insulation layer is provided on the inner wall of the cylinder. The main function of the heat insulation layer is to reduce heat dissipation and improve heating efficiency. Through this heat insulation layer, a higher temperature can be maintained inside the cylinder, enabling the heat of the heating component to act more concentratedly on the target object, thereby reducing energy waste.

[0036] In another embodiment of the present application, as Figure 1 and Figure 2 shown, a junction box is provided outside the cylinder.

[0037] In another embodiment of the present application, as Figure 1 and Figure 2 shown, a control system and a power supply line are provided inside the junction box; the control system controls the power supply line; the power supply line is connected to the conductive electrode and the external power supply. The setting of the junction box enables the power supply line and the control line of the device to be centrally managed, facilitating connection and operation by the user. At the same time, the junction box also plays a certain protective role, preventing the power supply line and the control line from being interfered with and damaged by the external environment. The control system realizes the switching and temperature adjustment of the heating component by controlling the on-off of the power supply line. This design enables the user to conveniently control the working state of the heating component and achieve precise temperature control. At the same time, the power supply line is connected to the conductive electrode and the external power supply, ensuring the stable transmission of current and providing guarantee for the normal operation of the heating component.

[0038] In another embodiment of the present application, as Figure 1 and Figure 2As shown, there are inlet and outlet pipes at both the inlet and outlet. The inlet and outlet pipes are provided with conical openings, and a circle of semi-circular grooves are provided on the end face of the conical openings. The semi-circular grooves facilitate the setting of sealing rings when connecting to other pipes subsequently, improving the sealing performance of the connection.

[0039] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
