Abstract

Przedmiotem zgłoszenia jest układ chłodzenia czół uzwojenia (1) silnika trakcyjnego bazujący na żywicy termoprzewodzącej (2) wypełniającej przestrzeń pomiędzy czołami uzwojenia (1) i kadłubem (3). W żywicy (2) są umieszczone łukowe elementy (4) z materiału o dużej przewodności cieplnej. Każdy z elementów (4) wykonany jest z materiału o dużej przewodności cieplnej, korzystnie z aluminium lub korundu i ma kształt wycinka pierścienia o łuku α, i długości osiowej L. Liczba elementów (4) korzystnie jest równa lub większa od liczby biegunów maszyny, (α ≤ ), gdzie p jest liczbą par biegunów. Po obu stronach elementu (4) znajduje się żywica termoprzewodząca (2), lecz elementy (4) nie stykają się z izolacją czół (1) uzwojenia i z powierzchnią kadłuba (3). Korzystnie jest, żeby elementy (4) stykały się czołowo z pakietem blach stojana (5), a ich (4) długość osiowa L była zbliżona do długości wysięgu czół uzwojenia (1).The subject of the application is a cooling system for the winding faces (1) of a traction motor based on thermally conductive resin (2) filling the space between the winding faces (1) and the hull (3). In the resin (2) arc elements (4) made of a material with high thermal conductivity are placed. Each element (4) is made of a material with high thermal conductivity, preferably aluminum or corundum, and has the shape of a section of a ring with arc α and axial length L. The number of elements (4) is preferably equal to or greater than the number of poles of the machine, ( α ≤ ), where p is the number of pairs of poles. On both sides of the element (4) there is a thermally conductive resin (2), but the elements (4) are not in contact with the insulation of the winding faces (1) and the surface of the hull (3). It is preferable that the elements (4) are in frontal contact with the stator plate pack (5), and their (4) axial length L is close to the projection length of the winding ends (1).
