METHOD FOR TRANSFERRING HEAT USING PRINCIPLE OF HEAT TRANSFER TUBE

摘要

PURPOSE: To optimize a heat transfer efficiency by so vibrating liquid in a vibrating frequency that an area ratio of a boundary layer of a sectional area in a connecting tube to the other part becomes a special value. ;CONSTITUTION: When liquid is vibrated by a vibration generator 4 and heat is transferred from a high temperature tank 1 to a low temperature tank 2, a ratio of an area A of a boundary layer 5 part to an area B of the other part is varied, if a vibrating frequency of the liquid is constant, in response to an inner diameter of a connecting tube 3, thereby altering a heat transfer efficiency. Here, the vibrating frequency of the liquid is so decided that the ratio A/B of the area A of the layer 5 part to that B of the other part falls within a range of 0.8-1.7, and the vibration is vibrated in the frequency. According to this method, a heat transfer efficiency of the tube having an arbitrary inner diameter can be substantially optimized.;COPYRIGHT: (C)1993,JPO&Japio
