Abstract
Description
technical field
[0001] The invention relates to the technical field of electronic communication, in particular to a frequency conversion electromagnetic heating energy-saving system. Background technique
[0002] The existing electromagnetic heating technology is not very mature, and has the following disadvantages: large heat loss, the traditional electric heating industry generally adopts resistance wire, electric heating rod, electrode and quartz heating methods, and this traditional heating method, its thermal efficiency In comparison, resistance wires, electric heating rods, electrodes and quartz mainly generate heat by themselves after being energized and then transfer the heat to the barrel or container, thereby heating the objects. The heat utilization rate of this heating effect is the highest. Only about 50%-80%, heat loss as high as 20%-50% or more; short service life: large amount of maintenance. Because the electric heating tube uses resistance wire, electric h...
