[0019] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4As shown, an embodiment of the utility model provides a tungsten alloy variable current heating device, including a main body mechanism 1 and a heating mechanism 2. The heating mechanism 2 is installed inside the main body mechanism 1. The main body mechanism 1 includes a shell 11, an insulation layer 12, a controller 13 and a support plate 14. The heating mechanism 2 includes a center rod 21, a spiral tube 22, a spiral heating rod 23 and a temperature sensor 24. The spiral tube 22 is arranged inside the shell 11, and the spiral heating rod 23 is installed inside the spiral tube 22. Both ends of the spiral tube 22 pass through the shell 11.

[0022] In one embodiment, a temperature sensor 24 is installed on the inner wall of the spiral tube 22 ; the temperature of the fluid in the spiral tube 22 is detected by the temperature sensor 24 .

[0023] In one embodiment, the bottom of the spiral tube 22 is fixedly connected to a support plate 14 , and the bottom of the support plate 14 is fixedly connected to the inner wall of the shell 11 ; the spiral tube 22 is supported and fixed by the provision of the support plate 14 .

[0024] In one embodiment, the outer wall of the shell 11 is fixedly connected with a heat-insulating layer 12 ; through the provision of the heat-insulating layer 12 , the temperature inside the shell 11 is insulated, thereby improving thermal efficiency.

[0025] In one embodiment, a controller 13 is installed on one side of the housing 11 ; through the setting of the controller 13 , the power of the spiral heating rod 23 is adjusted according to the fluid temperature detected by the temperature sensor 24 .

[0026] In one embodiment, the spiral heating rod 23 is made of tungsten alloy. During the heating startup phase, due to the low temperature and high resistivity of the tungsten filament, a large voltage drop will be generated when current passes through, resulting in a slow heating rate. As the temperature of the tungsten filament increases, the resistivity gradually decreases, the number of collisions between electrons and tungsten filament atoms increases, and the heating rate accelerates until a dynamic equilibrium state is reached. During the constant temperature heating phase, the tungsten filament maintains a stable resistivity, achieving a constant heating power output.

[0027] When the present invention is working: first, one end of the spiral tube 22 is connected to the fluid delivery pipe, the fluid enters the spiral tube 22, and contacts the spiral heating rod 23 inside the spiral tube 22. A gap is maintained between the spiral tube 22 and the spiral heating rod 23 to ensure that the fluid can flow smoothly and be heated evenly. The fluid forms a vortex during the heating process, which improves the heat exchange efficiency. The temperature of the fluid in the spiral tube 22 is detected by the temperature sensor 24, and the controller 13 adjusts the power of the spiral heating rod 23 according to the fluid temperature detected by the temperature sensor 24.

[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
