Description

1one

Известны полые проводники, например, дл  обмоток электрических машин, на внутренней поверхности которых выполнены продольные пазы.Hollow conductors are known, for example, for windings of electrical machines, on the inner surface of which longitudinal grooves are made.

Предложенный полый проводник отличаетс  от известных тем, что, с целью повышени  эффективности охлаждени  продольные пазы выполнены по винтовой линии.The proposed hollow conductor differs from the known ones in that, in order to increase the cooling efficiency, the longitudinal grooves are made along a helical line.

На фиг. 1 показан полый проводник в продольном разрезе; на фиг. 2 - то же, в поперечном разрезе.FIG. 1 shows a hollow conductor in longitudinal section; in fig. 2 - the same in cross section.

Дл  циркул ции теплоносител  в теле проводника 1 имеетс  канал 2 с пазами 3. Пазы 3 выполнены по винтовой линии. При циркул ции теплоносител  по каналу 2 осуществл етс  поступательно-вращательное движение потока , вследствие чего происходит интенсивное перемешивание холодных и теплых слоев теплоносител .For the circulation of the coolant in the body of the conductor 1 there is a channel 2 with grooves 3. The grooves 3 are made along a helix. During circulation of the coolant through the channel 2, the translational-rotational flow is carried out, as a result of which there is an intensive mixing of cold and warm layers of the coolant.

Предмет изобретени Subject invention

Полый проводник, например, дл  обмоток электрических машин, на внутренней поверхности которого выполнены продольные пазы, отличающийс  тем, что, с целью повышени  эффективности охлаждени , каждый из указанных пазов выполнен по винтовой линии.A hollow conductor, for example, for windings of electrical machines, on the inner surface of which longitudinal grooves are made, characterized in that, in order to increase the cooling efficiency, each of said grooves is made along a helical line.
