The invention relates to a heat supply device for a high-frequency eddy pipeline, and belongs to the technical field of electric heating. The heat supply device comprises a pipeline, wherein a coil is wound on the pipeline; an insulating layer is arranged between the pipeline and the coil; the coil is electrically connected with an inverter circuit; and the inverter circuit is electrically connected with a rectification circuit. In the heat supply device, the heat efficiency is more than 95 percent, the preheating time is shortened by 2 / 3, and compared with a resistance-type heating device, the heat supply device saves electricity by more than 25 percent under the same condition. The heat supply device can prevent scales and microbial membranes, prolong the service life, prevent the pollution of chemical cleaning to environment and save energy.
Description
technical field [0001] The invention belongs to the technical field of electric heating, and in particular relates to a high-frequency eddy current pipeline heating device. Background technique [0002] The existing metal pipeline system, because the internal liquid will freeze at low temperature, or the internal scale and microbial film will be generated when it is used for a long time, a heating device is required, and a resistance heater is generally used. The thermal efficiency of the device is low, and the preheating time is long. Electricity. Contents of the invention [0003] The object of the present invention is to provide a high-frequency eddy current pipeline heating device with high thermal efficiency, short preheating time, environmental protection and energy saving. [0004] The object of the present invention is achieved in this way: the high-frequency eddy current pipeline heating device includes a pipeline, a coil is wound on the pipeline, an insulation l...
