<p>PURPOSE:To reduce the maximum temperature in a section by a method wherein a flow-controlling member is provided inside or outside insulating cylinder side forming the circuit space near each circuit space so that a cooling medium passing through each circuit space flows aslant on the side of the section. CONSTITUTION:Flow-controlling members 21, 22 are provided near circuit spaces 6, 7 so that a cooling medium passing through each of circuit spaces 6, 7 flows aslant on the side of the section. Means for arranging the flow-controlling members 21, 22 is optical, and an outside barrier 5 and an inside barrier 4 are integrally provided. Thus, a flow speed of the cooling medium can be made uniform and a difference in a temperature among respective sections can be averaged and the maximum temperature in the sections can be reduced.</p> |
