Zusammenfassung: | electrical engineering for rail transport and other industries. SUBSTANCE: proposed case has walls with longitudinal and transverse groups of parallel ribs on their surfaces. Novelty is that mentioned groups of ribs are arranged on different sides of walls and are made of L-shaped strips. Longitudinal groups of parallel ribs are arranged on inner or outer sides of wall and transverse groups, on outer or inner sides. EFFECT: improved heat transfer; reduced mass and increased mechanical strength of case. 3 dwg |
