[0021] See also Figure 1-3 The utility model provides a technical solution: a heater, comprising a shell 1 and a high-frequency power controller 2 arranged in the shell 1, an induction heating coil 3 arranged outside the shell 1 and connected to the high-frequency power controller 2, the front end of the shell 1 is provided with a conductive heat sink 4, the two conductive heat sinks 4 are symmetrically provided, an isolation gap is provided between the two conductive heat sinks 4, and the two conductive heat sinks 4 are respectively connected to one end of the power output of the high-frequency power controller 2, the two ends of the induction heating coil 3 are correspondingly connected to the two conductive heat sinks 4, a cooling fan 5 is provided at the rear end of the conductive heat sink 4 in the shell 1, the high-frequency power controller 2 is installed at the rear end of the cooling fan 5, and the high-frequency power controller 2 is provided with cooling fins 6, and ventilation holes 7 are respectively provided at the front end of the shell 1 and the rear end of the high-frequency power controller 2.

[0022] The high-frequency power supply is output to the induction heating coil 3 through the high-frequency power supply controller 2, so that the induction heating coil 3 generates high-frequency electromagnetic waves for heating the workpiece. During the operation of the high-frequency power supply controller 2, the cooling fan 5 starts to run synchronously, and the cooling fan 5 draws air from the ventilation holes 7 at the rear end of the shell 1 and blows it out from the ventilation holes 7 at the front end of the shell 1, so that the air flow passes through the shell 1, and the heat generated by the operation of the high-frequency power supply controller 2 passes through the heat dissipation fins 6 and the heat generated during the heating of the workpiece and is introduced into the interior of the shell 1 through the induction heating coil 3 and located on the conductive heat sink 4. The heat is dissipated by the penetrating air flow, so that the shell 1 is in a preset cooling effect, thereby improving the product operation effect and service life.

[0023] The conductive heat dissipation element 4 includes a substrate 41, a heat dissipation plate 42 and a mounting plate 43. A plurality of heat dissipation plates 42 are evenly and vertically arranged on the substrate 41. Heat dissipation ducts are arranged between the heat dissipation plates 42 at intervals, and the direction of the heat dissipation ducts is consistent with the direction of the two ventilation holes 7 in the shell 1. The mounting plate 43 is arranged on the substrate 41 in parallel with the heat dissipation plates 42. Heat dissipation ridges 44 are evenly distributed on the surface of the heat dissipation plates 42. The setting direction of the heat dissipation ridges 44 on the heat dissipation plates 42 is consistent with the direction of the heat dissipation ducts.

[0024] The mounting plate 43 is located in the middle of the base plate 41 , and the base plate 41 , the mounting plate 43 , the heat dissipation plate 42 and the heat dissipation ridges 44 are integrally formed by metal injection molding.

[0025] By providing multiple heat dissipation plates 42, heat dissipation ribs 44 and integral injection molding, the heat conduction efficiency and heat dissipation efficiency of the conductive heat dissipation element 4 are improved, further improving the cooling effect of the product.

[0027] The provision of the jack 45, the positioning screw hole 46 and the set screw facilitates the maintenance and replacement of the induction heating coil 3, and allows the replacement of induction heating coils 3 of different specifications according to the size of the workpiece to be heated. The provision of the high-temperature resistant insulating hand-tightening screw reduces the need for intervention of other tools, thereby improving the use effect.

[0028] The front end of the shell 1 is provided with a high-temperature resistant insulating fixing frame 8 for fixing two conductive heat dissipation parts 4, the front end of the shell 1 is provided with a protective cover 9 that is sleeved on the outside of the high-temperature resistant insulating fixing frame 8, the front end surface of the protective cover 9 is provided with ventilation holes 7, the front end of the high-temperature resistant insulating fixing frame 8 is provided with an indicator light 10 connected to the high-frequency power supply controller 2, and the indicator light 10 extends to the outside of the protective cover 9.

At the same time, in actual application, the indicator light 10 can be set as a multi-color indicator light 10, and the indicator light 10 displays different colors according to the actual operating status of the product.
