Abstract

PURPOSE: To dercease a temperature of a driving motor greatly without changing its configuration and dimensions by instituting monolithic cooling fins in an internal side of an impeller blade.
CONSTITUTION: A cold flow 112 is generated by providing an internal side of an impeller 103 with a plurality of cooling flow fins 105 causing agitations of an ambient air by means of the cooling flow fins 105 when the impeller rotates. Hence, a surface temperature of a driving motor 107, and a coil temperature, or a temperature of a bearing 109 and a temperature of a casing 101 are greatly lowered. Therefore, even though a carrier fluid inside the spiral flow type blower is a high temperature fluid, a bearing 109 is cooled and a sufficient capacity is obtainable without increasing its configuration and dimensions.
