Title:
ELECTROMAGNETIC INDUCTION HEATING DEVICE
Document Type and Number:
Japanese Patent JP2020024833
Kind Code:
A
Abstract:
To provide an electromagnetic induction heating device that, without reducing the efficiency in heating an object to be heated, can cool magnets for heating the object to be heated.SOLUTION: An electromagnetic induction heating device 100 comprises a table 101 that retains a plurality of magnets such that the magnets face an object to be heated WK. A heat sink 103 is formed on a back surface 101a of the table 101 opposite to the magnets 105, and the heat sink 103 is covered with a back-surface jacket 107. The heat sink 103 is formed annularly suspended from respective circumferences of four concentric circles having a center at the rotary drive center of the table 101, downward as shown in the figure and continuously along the circumferences. A cavity section 108 is formed between the back-surface jacket 107 and the back surface 101a of the table 101, and the back-surface jacket comprises a gas supplier 110 and a gas discharger 111 that respectively supply and discharge air to and from the cavity section 108.SELECTED DRAWING: Figure 1
