A HEAT TRANSFER METHOD AND DEVICE

摘要

A heat transfer device and method is disclosed. The heat transfer device comprises: a conduit having at least one mini dimension of less than 1 cm; and a viscoelastic fluid operable to flow through the conduit and to transfer heat from a heat source in thermal contact with the conduit. The conduit comprises one or more obstructions arranged at locations in the conduit, the obstructions are configured to partially block fluid flow and generate local instabilities in the fluid flow upstream of the obstruction thereby increasing heat transfer from the heat source at a location upstream of the predetermined location.
