In this specification, the space between the surfaces of the pair of electrically insulating supporting members 14 is defined as the inside of the electrically insulating supporting member 14. Accordingly, the outside of the curved portion 12 is inserted into the elongated hole 15 from the inside to the outside of the electrically insulating support member 14, and the curved portion 12 is inserted into the outside of the electrically insulating support member 14. And a ring-like stopper 16 having an outer diameter larger than the minor diameter of the long hole 15 for stopping the curved portion 12 from coming off from the long hole 15 is provided on each of the meandering cooling coils. At the outer periphery of the apexes of the two curved portions 12, that is, at the outer positions of the respective electrically insulating support members 14 (see FIGS. 3 and 4), the hermetically sealed heat exchanger B is fixed to the pair of electric It is supported between the insulating support members 14 and is piped (see FIG. 3). Preferably, the stopper 16 is hooked on the outer periphery of the apex of the curved portion 12 located near both ends of each electrically insulating support member 14.
It should be noted that even if the number of attachment points of the ring-like stopper 16 is increased in consideration of the assembling property and the attachment strength, it is within the scope of the present invention. For example, even if the stopper 16 is engaged with the curved portion 12 located at the intermediate portion of each electric insulating member 14, even if the number of the curved portions 12 to which the stopper 16 is attached is a majority, It is the scope of the invention.
The stopper 16 is formed of a ring-like band made of an elastic synthetic resin, and is fixed so as to surround at least ／ of the pipe of the curved portion 12.
The electrically insulating support member 14 is made of a channel material having a U-shaped cross section (see FIG. 5).
[0016]

Further, since each of the curved portions 12 is supported in a detached state by the stopper 16 attached from the outside of the electrically insulating support member 14, the brazed portion between the curved portion 12 and the pipe 11 is electrically insulated. Spraying water is also sprayed on a part of the U-shaped pipe near the brazed portion, which is located inside the elastic support member 14 (see FIG. 5), and the circulating cooling water flowing in the closed type heat exchanger B is indirect. Is cooled.
[0021]
Since the extreme tip of the curved portion 12 of the cooling coil in the heat exchanger B is supported by the pair of electrically insulating support members 14, the support span is slightly longer than the conventional one by a part of the U-tube. As a result, the contact area between the spray water sprinkled from the upper water tank and the heat exchanger B is somewhat increased, and the cooling capacity is somewhat increased.
