FIELD: heating systems. ^ SUBSTANCE: invention refers to design of tubular heat transfer surfaces of heat exchange devices for fluid media under pressure and can be used in oil, chemical and other industries, namely in oil and oil emulsion heaters. In single-flow tubular coil containing a row of straight tubes and connection elements on tube ends, connection element consists of a tube with holes along its generatrix for inserting straight tube in them; number of holes is equal to number of tubes in a row; in diametral planes of connection element there installed are plates comprising together with the wall of connection element the compartments through which cavities of tubes of the row, which are located in pairs, are connected. ^ EFFECT: simplifying the design, decreasing overall dimensions of coil, increasing surface area of tubes in overall volume of coil. ^ 2 dwg |
