Embodiment Construction

[0015] Such as figure 1 As shown, the intermediate frequency heating rod is composed of a magnetic core rod (1), a copper coil (2), an insulating layer (3), a ferromagnetic tube (4), a magnetic ring (5), a PTC temperature sensitive resistor (6) and a sealing end Part (7) is composed.

[0016] The magnetic core rod (1) is located on the central axis of the ferromagnetic tube (4), and the top of the magnetic core rod (1) is closed by a magnetic ring (5), and the outer diameter of the magnetic ring (5) is the same as the inner diameter of the ferromagnetic tube (4). Similarly, the copper coil (2) is tightly wound on the magnetic core rod (1), and the copper coil (2) is connected to an external intermediate frequency power supply. The copper coil (2) is mainly used to generate an intermediate frequency alternating magnetic field, and the magnetic force line forms a closed loop through the magnetic core rod (1), the magnetic ring (5) and the ferromagnetic tube (4); the magnetic ri...

Abstract

The invention discloses a medium-frequency heating bar and a structure thereof. The medium-frequency heating bar comprises a magnetic core bar, a copper coil, an insulation and heat-insulating layer, an iron magnetic tube, a magnetic ring, a PTC temperature-sensitive resistor and a sealing end, wherein the magnetic core bar, the copper coil and the insulation and heat-insulating layer are arranged in the iron magnetic tube, the magnetic ring and the sealing end perform sealing, and the built-in heating structure is formed. The heating bar is arranged in a heated object. When medium-frequency current flows in the copper coil, the iron magnetic tube generates heat, and therefore the heated object in contact with the outer wall of the iron magnetic tube is heated. The medium-frequency heating bar is small in energy consumption, high in efficiency, good in insulation sealing performance, convenient to control, long in service life, safer and applicable to various occasions needing the heating bar to perform heating.

Description

technical field [0001] The invention relates to a general heating rod, in particular to an intermediate frequency heating rod and its structure. It can be used in various occasions that need to use heating rods for heating. Background technique [0002] At present, heating rods made of resistance wire heating principles are widely used. The heating rods with this structure have disadvantages such as high energy consumption, low efficiency, poor insulation and sealing performance, inconvenient control, short life, and potential safety hazards. Therefore, the present invention makes corresponding improvements aiming at the deficiencies of the prior art. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an intermediate frequency heating rod and its structure with low energy consumption, high efficiency, good insulation and sealing performance, convenient control, long life and safety. [0004] The techn...
