HEAT DISSIPATION SYSTEM FOR ELECTROMAGNETIC COIL

WIPO Patent Application WO/2019/000837

A1

A heat dissipation system for an electromagnetic coil, comprising an electromagnetic coil (10), an injection assembly (20), and an air extractor (30). The electromagnetic coil (10) is provided with channels (11); The air extractor (30) is configured to extract air out of the channels (11), so that the channels (11) are in a negative pressure state. The injection assembly (20) is configured to inject to the inner walls of the channels (11) an insulating coolant which is vaporized when the electromagnetic coil (10) emits heat and the channels (11) are in the negative pressure state. Through the use of a combined design of the electromagnetic coil (10), the injection assembly (20) and the air extractor (30), the injection assembly (20) can be used to inject the insulating coolant to be in a direct contact with the electromagnetic coil (10) for heat exchange; and meanwhile, a lot of heat can be taken away through the vaporization of the insulating coolant, so that the heat dissipation effect of the electromagnetic coil (10) can be greatly improved under double action of heat exchange through direct contact with jet flows and heat absorption through vaporization.
