Title:
ELECTROMAGNETIC INDUCTION HEATING UNIT AND AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/079570
Kind Code:
A1
Abstract:
Provided are an electromagnetic induction heating unit and an air conditioning device, wherein even if electromagnetic induction heating is performed by generating a magnetic field using an electromagnetic induction heating unit, the magnetic field leaking to the outside of a refrigerant pipe can be reduced. An electromagnetic induction heating unit (6) for electromagnetic induction-heating a refrigerant pipe (F) is comprised of a coil (68), a shielding cover (75), and ferrites (98, 99). The coil (68) is disposed in the vicinity of the refrigerant pipe (F). The shielding cover (75) is arranged around the refrigerant pipe (F), and contains a magnetic substance. The ferrites (98, 99) are disposed on the outer side of the coil (68), which is opposite to the inner side of the coil (68) adjacent to the refrigerant pipe (F), and on the inner side of the shielding cover (75), and contain a magnetic substance having a magnetic permeability higher than that of the shielding cover (75). In a direction in which the refrigerant pipe (F) extends, the opposed ends of the shielding cover (75) are disposed at a position further inside than the opposed ends of the ferrites (98, 99).
