HEAT-TRANSFER TUBE FOR SINGLE-PHASE FLOW IN TUBE

摘要

An objective of the present invention is to provide a heat-transfer tube for a single-phase flow in a tube. According to the present invention, a heat-transfer tube for a single-phase flow in a tube includes a corrugated tube having a spiral groove on the outer surface. The heat-transfer tube for a single-phase flow in a tube has single-phase fluid flowing in a tube to perform heat exchange between the single-phase fluid with fluid, substance, or radiant heat outside the tube. The heat-transfer tube for a single-phase flow in a tube has an outer diameter (OD) of a tube 6-20 mm, an inner diameter (ID) 5-19 mm, and a pitch (Pc) in an axial direction of the groove 15-25 mm. In addition, the heat transfer tube for a single-phase flow in a tube has copper or copper alloy as material of the tube. Also, if Dc refers to the depth of the corrugated groove, Dc/ID is 0.051-0.097.;COPYRIGHT KIPO 2015
