    摘要: In a totally-enclosed type motor, internal cooling air is passed through internal ventilation passages (4a) provided inside a stator frame (4) by an internal fan (9), and external cooling air is passed through external ventilation passages (4b) provided on the outside of the stator frame (4) by an external fan (12). Archly extending inner heat radiation ribs (4c) are provided on the inner surface of the ventilation passages (4a). The raise in temperature is reduced by an improvement in the cooling characteristic, thereby permitting a compact totally-enclosed type motor.

    摘要: A heat transfer wall and a method of producing same, including a multiplicity of minute tunnels parallelly extending and spaced a minuscule distance from each other under an outer surface of the wall in contact with liquid, and a multiplicity of tiny hole portions formed at the outer surface of the wall above the tunnels and located at regular intervals along the tunnels to maintain same in communication with the outside. Each hole portion includes a projection located in the hole portion including a hole itself and extending from the vicinity of the hole portion into the hole portion in a manner to traverse same, so that a flow of liquid into the tunnels and a flow of vapor out of the tunnels can be optimally regulated by the projections to enable the heat transfer wall to exhibit a high heat transfer performance.
