Abstract

PURPOSE: To intend to increase circulating flow amount and improve cooling capacity, by forming the transformer such that riser part of piping from tank and under upper connecting part of radiator from tank are insulated.
CONSTITUTION: Under connecting part 11 with upper piping part 10 of radiator 5 of riser part 7 of piping from tank 3 in upper part piping 4 is insulated with insulating material 8, and also, the connecting part 11 is connected with member 9 such as flange, bolt and the like which are composed of stainless steel whose thermal conductivity is low. Therefore, oil which is raised by being heated in the tank 3 is cooled at the riser part 7, partially downward stream is generated, prevention of driving power of oil circulation is eliminated, and also, oil is insulated at the connecting part 11. From this circulation, oil is cooled from piping riser part 10 side, partial down stream to riser part 7 is eliminated and cooling capacity can be improved.
