FIELD: heating engineering. ^ SUBSTANCE: developed heat-exchange surface can be used in heat exchangers, steam and hot water boilers, and boilers-exhausts. Developed heat-exchange surface has heat-exchange surface and set of hollow rods disposed inside holes of heat-exchange surface. Edges of rods are plugged at the sides from where the heat is supplied. Set of hollow rods can be disposed along both sides of heat exchange surface or only at the side from where the heat is supplied. Heat-exchange surface has cylindrical or flat shape. ^ EFFECT: improved accrual of heat exchange. ^ 7 cl, 12 dwg |
