Трубчатые ребристые поверхности с интенсифицированным теплообменом и технология их изготовления для аппаратов воздушного охлаждения топливно-энергетического комплекса

The paper presents designs of bimetallic ridge pipes (BRP) with spirally-wound aluminium KLM-edges for heat exchange air coolers. Heat exchange BRP differ from the applied ones in heat-transfer coefficient which is higher by 10–15 %, extended temperature of applicability up to 320 °С for a cooled heat carrier at the pipe input, higher thermal reliability at alternating thermal burdens, current consumption for their manufacturing which is less by 1.8–2.5-fold, aluminium consumption which is less up to 1.8-fold, manufacturability in batch production,  availability high-production equipment.
