[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A heat-resistant and corrosion-resistant alloy electromagnetic heater is provided, comprising an oscillation circuit, a mounting shell, and a heating mechanism. The oscillation circuit includes a field-effect transistor, an inductor coil, a power supply, a capacitor, and copper wire. One end of the copper wire away from the field-effect transistor is fixedly connected to an interface. The heating mechanism includes a heat-insulating shell and a heating coil. A heat-resistant tube is fixedly connected inside the heat-insulating shell, and a corrosion-resistant coating is fixedly disposed inside the heat-resistant tube. The heating coil is spirally sleeved on the outer wall of the heat-resistant tube, and the two ends of the heating coil are... The heat insulation shell is fixedly connected to a joint. A mounting plate and a sleeve are fixedly connected to one side of the outer wall of the heat insulation shell. A support column and a locking plate are fixedly connected to the outer wall of the mounting shell. The mounting plate is movably connected to the locking plate. Sliding grooves are opened near the front and rear positions of the locking plate. Pressure plates are slidably connected in both sliding grooves. Sliding rods are fixedly connected in both pressure plates. Side holes are opened on the front and rear outer walls of the mounting plate. Sliding rods are movably connected in the side holes. Springs are fixedly connected between the pressure plates and the inner walls of the sliding grooves.

[0007] Optionally, the heat-resistant pipe is made of silicon carbide, and the corrosion-resistant coating is made of modified epoxy resin.

[0008] Optionally, the interface is fixedly connected to the outer wall of the mounting housing, and the opening of the interface extends through the mounting housing, with the connector and interface being mutually matched.

[0009] Optionally, both ends of the heat-resistant tube are provided through the heat-insulating shell, and the spring is movably connected to the outer end of the slide rod.

[0010] Optionally, the support column is movably connected inside the sleeve, and there are two of each support column and sleeve. The two support columns are respectively located on the front and rear sides of the locking plate, and the two sleeves are respectively located on the front and rear sides of the mounting plate.

[0011] Optionally, a radiator and an exhaust pipe are fixedly connected inside the mounting housing. An insulating gasket is fixedly connected between the upper end of the radiator and the field-effect transistor by bolts. The air outlet of the exhaust pipe is located on one side of the heat dissipation fins of the radiator. An air guide box is fixedly connected to the air inlet of the exhaust pipe. A fan is connected inside the air guide box. A filter screen is fixedly connected inside the air inlet of the air guide box. The air guide box is installed through the side plate of the mounting housing. A heat dissipation vent is opened on one side of the mounting housing. The heat dissipation vent is located on the side of the radiator away from the exhaust pipe.

[0012] Optionally, a pin is fixedly connected to one side of the field-effect transistor, and a resistor and a rectifier diode are soldered onto the pin respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model includes an interface, a support column, a heating mechanism, a locking plate, a pressure plate, a slide rod, and a spring. It allows the heating coil to operate via a connector sleeve, and a sleeve fitted onto the outer wall of the support column for guidance. The connection between the support column and the sleeve reduces the gravitational load at the interface and connector connection. Furthermore, the mounting plate is movably fitted into the locking plate, and the slide rod is fitted into the side hole of the mounting plate for fixation. This prevents deformation of the interface and connector due to the weight of the heating mechanism, improving the stability of the connection. By pulling the slide rod away from the side hole of the mounting plate, the oscillation circuit can be separated from the heating mechanism, facilitating repair and replacement of the corresponding components in case of malfunction. In addition, the heat-resistant tube and the corrosion-resistant coating sprayed on the inner wall of the tube enhance the heat and corrosion resistance of this utility model.

[0016] 2. This utility model is equipped with a heat dissipation port, a heat sink, an exhaust pipe, an air guide box, a fan, and a filter. During operation, the heat sink dissipates heat from the field-effect transistor, which generates significant heat. In conjunction with the fan, external airflow is drawn through the air guide box into the exhaust pipe and blown between the multiple fins of the heat sink, expelling the high-temperature gas from the heat dissipation port. This further improves the heat dissipation efficiency of this utility model, thereby enhancing its heat resistance. Attached Figure Description
