PURPOSE:To obtain a better cooling characteristic by a proper layout and shape of a fastening member between the container and coils and spacers between the adjacent conductive coils. CONSTITUTION:A fastening member 4 is arranged on a spacer 3 corresponding to a passage outlet C of the refrigerant in such a manner as to have a refrigerant guiding surface matching the refrigerant guiding surface the space 3. As a result, as the passage outlet C becomes level, air bubble generated during heat exchange of the refrigerant flows upward in the direction of the arrow without stallmating at this point. Cooling of the coil 2 by the air bubbles can be prevented enabling continuation of safe operation. |
