Embodiment Construction
[0023] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:
[0024] Such as figure 1 , 2 As shown, it is a heat-conducting oil furnace heater of the present invention, which includes an outer cylinder 1 and an electromagnetic heating coil 2 wound outside the outer cylinder 1. The outer cylinder 1 is a seamless steel pipe with a thickness of 1 cm, and a helical coil is arranged in its cavity. Shaped conduit 3, the conduit 3 is used to convey the medium, the axis of which is consistent with the axial direction of the outer cylinder 1, and the tube wall of the conduit 3 is closely attached to the inner wall of the outer cylinder 1 to reduce heat loss.
[0025] The above-mentioned conduit 3 is formed by butt jointing of multiple conduit units, and the joint is 31. The conduit units are made of copper tubes, aluminum tubes or steel pipes, and the materials selected for two adjacent conduit units are different.

The invention discloses a heat-conduction oil furnace heater comprising an outer barrel and an electromagnetic heating coil which is wound outside the outer barrel; a barrel cavity of the outer barrel is internally provided with at least one spiral conduit which is used for conveying mediums; an axis of the spiral conduit is consistent with the axial direction of the outer barrel; the spiral conduit is formed by a plurality of conduit units via butt joint; and calibers of the two adjacent conduit units at the joint of the two conduit units are less than the calibers at the middle parts of the two conduit units. Compared with the prior art, the heat-conduction oil furnace heater has the advantages as follows: the conduit is formed by a plurality of conduit units via butt joint and the calibers at the joints are arranged less, then when mediums flow through the conduit units, larger friction is generated by means of pressure change and the mediums are capable of generating certain available energies, so that the output power of the electromagnetic heating coil is decreased and the loss of electric energy is reduced.
Description
[0001] technical field [0002] The invention relates to a device for heating a fluid by electromagnetic induction, in particular to a heat conduction oil furnace heater. [0003] Background technique [0004] Heat-conducting oil furnaces are widely used in industrial production, and the heating device is a key component of heat-conducting oil furnaces. [0005] The existing heat conduction oil furnace heating devices all include an outer cylinder, an electromagnetic heating coil is wound outside the outer cylinder, and a plurality of tubes are installed in the outer cylinder, and these tubes are arranged in an array and extend along the length direction of the outer cylinder. One end of the tubes is input and flows in the tubes, the electromagnetic heating coil heats the tubes in the length direction of the outer tube, the heat is finally transferred to the medium in the tubes, and the higher temperature flows out at the output end of the tubes medium. During the use of ...
