This is the same part as in FIGS. 4 and 5. (12) is a pair of common liquid reservoirs mounted on both sides of the upper part of the vessel (5), and (13) is a common liquid reservoir (12) in parallel with the upper part of each coil (2). A plurality of liquid feed channels (13) that guide the (). The liquid feeding channel (13) may be an opening of a square member as shown in FIG. 3, or may be a tubular shape such as a square shape or a round shape.

It is forcibly guided only to each coil (2) by 3).
Therefore, the coil (2), which is a heating element, is intensively cooled by the refrigerant liquid dropped from the liquid feeding channel (13), and the refrigerant liquid (6) is involved in the portion such as the washer (3) that does not need to be cooled. Therefore, the refrigerant liquid (6) works efficiently, and the amount thereof can be reduced.
