Electromagnetic heating temperature-control system and air cooling system thereof

Abstract

The invention provides an air cooling system of an electromagnetic heating temperature-control system. The air cooling system includes a heat radiation portion comprising heat conduction strips, a radiating fin and an air channel, and a wind power source. The heat conduction strips are at least two with length directions perpendicular or nearly perpendicular to a winding direction of an electromagnetic coil of the electromagnetic heating temperature-control system, and each are provided with a striped structure in close contact with an outer wall of a temperature-control object of the electromagnetic heating temperature-control system. The air channel is formed between the radiating fin and the outer wall of the temperature-control object and / or other parts of the heat radiation portion. An outlet of the wind power source is connected to an inlet of the air channel. The air cooling system and the electromagnetic heating temperature-control system using the air cooling system minimize leakage flux, improve heating efficiency and heat radiating efficiency, prevent vortex in air-cooled structural components, and achieve the purposes of stable temperature control and efficient energy-saving.

AI Technical Summary

Problems solved by technology

[0008] 1) The existing technology uses organic materials as the outer wall of the air duct, and under heating, the organic material will often soften or even decompose, making the air duct easy to collapse, resulting in poor cooling and prone to accidents due to overheating;

[0009] 2) Since the air duct in the prior art is inserted between the barrel and the heat insulation layer, and the electromagnetic coil is wrapped outside the heat insulation layer, the existence of the air duct leads to large leakage flux, low magnetic field utilization rate, and poor heating efficiency;

[0010] 3) Since the heat insulation layer is wrapped outside the air duct, the heating efficiency is low, the heat insulation effect is poor, and the heat dissipation effect is also poor
